Do I need a property inspection when buying a new construction condo in Mexico?

Yes — though the inspection looks different than for a resale property. On a completed new construction or newly delivered pre-construction unit, an inspection should verify: that the unit as built matches the approved plans and your purchase agreement specifications (square footage, finishes, fixture models), that all building systems are installed and operational (electrical, plumbing, HVAC, water systems), that the structural concrete shows no construction defects (honeycomb concrete, insufficient rebar coverage), and that the common areas are completed as represented in the developer's marketing materials. For pre-construction properties being inspected before final payment, the inspection is your primary mechanism for documenting punch-list defects that the developer must repair before you close. Have your inspector document every defect in writing with photographs — deliver the list to the developer in writing and require written confirmation of cure before releasing your final payment. A new build inspection costs $200–$400 USD and protects your leverage in negotiations over defects and construction quality.

What is a cistern and tinaco, and why do they matter for a property inspection?

In Mexico's coastal and semi-urban markets, municipal water supply is frequently intermittent — available for a few hours per day or at insufficient pressure for direct use. The residential water system consists of two storage components: the cistern (aljibe or cisterna), an underground concrete or polyethylene tank typically holding 10,000–20,000 litres, which stores incoming municipal water; and the tinaco, a rooftop polyethylene or fiberglass tank of 500–2,500 litres that is filled by a pump from the cistern and provides gravity-fed pressure to all interior fixtures. For a property inspection, the cistern condition matters because concrete cisterns can crack and contaminate the water supply, while polyethylene models can leach chemicals if aged beyond their useful life. The tinaco condition matters because UV-degraded polyethylene becomes brittle and can fail structurally, and a small, deteriorated tinaco means low water pressure throughout the property. A functioning, properly sized cistern-tinaco system is the water infrastructure of the property — not a backup system. Inspectors should physically open cistern access hatches and visually inspect interior condition.

What does an ejido risk check involve for a property in Mexico?

Ejido land originates from Mexico's post-revolutionary agrarian reform, which distributed millions of hectares of land to farming collectives (ejidos) who held it communally. Under the 1992 amendment to Article 27 of the Constitution, ejido land can be converted to private title through a process called dominio pleno — but only after a formal assembly vote by the ejido's members and registration with the Registro Agrario Nacional (RAN). Properties built on ejido land that was never properly converted to private title have a legally defective ownership chain. Foreign buyers have lost entire properties — including completed structures — when ejido members or courts ruled that the conversion was invalid, incomplete, or fraudulently documented. In Tulum and parts of Oaxaca's coast in particular, rapid development outpaced the legal conversion process, leaving a legacy of title complications. An ejido risk check requires your buyer's attorney to search the Registro Agrario Nacional for any ejido designation on the property's parcel, review the conversion history if applicable, and obtain a legal opinion on whether the title chain is clean from both the Public Registry (private title) and the agrarian registry (ejidal tenure) perspectives. Properties with any history of ejidal tenure deserve heightened scrutiny and a clear legal opinion before you commit.

What hurricane-related construction features should I check in a Mexico property?

For properties in Quintana Roo, the Caribbean coast, and parts of BCS, hurricane resilience is a material property feature — not a nice-to-have. Construction standards for hurricane-zone properties in Mexico include: impact-resistant glazing (required by code for new construction in high-risk zones), concrete block or reinforced concrete construction (wood-frame structures are extremely rare in coastal Mexico and represent a serious hurricane risk), adequate column and beam dimensions per Mexico's seismic and wind codes (NTC-Viento for Mexico City; state building codes for coastal states), and roof system designed for the wind uplift loads applicable to the location. Ask your inspector specifically: Is the glazing impact-rated or hurricane-film-treated? What is the roof structure — is it a concrete slab (best), a concrete beam system, or a wood/metal roof deck over concrete walls? Are there proper lintels over all openings? Is the roof-to-wall connection hurricane-strapped? For a property in a Cat 4/5 hurricane risk zone (Cancún, Playa del Carmen, Tulum, Cozumel), the difference between a properly engineered structure and one that was built to minimum pre-code standards is the difference between post-hurricane repairs and post-hurricane total loss.

How do I check if a property has proper building permits in Mexico?

Building permit records in Mexico are held by the municipal Dirección de Desarrollo Urbano (or equivalent department — municipality name varies). Your buyer's attorney should visit the municipal office in person or submit a formal request to obtain the permit history for the property's address or parcel number. They are looking for: the original construction permit (licencia de construcción) and the final occupancy certificate (licencia de uso de suelo or constancia de terminación), plus any subsequent permits for renovations, expansions, or additions. Permit records should match the physical property — if the property has three bedrooms and the permit covers two, the third bedroom is an unauthorized addition. In practice, minor informal additions (a storage room, a small covered terrace) are common in older Mexican properties and are not necessarily deal-breakers — the question is whether they can be retroactively regularized (through a process of regularización with the municipality) and at what cost. Major structural additions without permits, or construction in ecological protection zones, zoning setbacks, or coastal buffer zones, are harder to regularize and may be uninsurable or subject to demolition orders.

Should I hire a Canadian home inspector or a Mexican inspector for a property in Mexico?

A Mexican inspector with specific experience in the market and property type you're purchasing is the right choice, not a Canadian inspector. The reasons are concrete: Canadian inspectors are trained to assess properties built to Canadian Building Code standards — wood-frame construction, forced-air HVAC, basements, high-slope roofs, four-season weatherproofing, and 120/240V electrical systems. None of these features are present in Mexican coastal construction. A Canadian inspector in Mexico is encountering cisterns, tinacos, azotea flat roofs, 127V single-phase electrical systems, septic fields in tropical soil, concrete block and column construction, and ejido-adjacent title risks for the first time. Their report will miss Mexico-specific failure modes and may flag things that are completely normal in the Mexican context. Conversely, a good Mexican inspector who regularly works in the specific market (Puerto Vallarta, Playa del Carmen, Los Cabos) knows exactly where these properties fail, what the local construction quality range looks like, and which red flags are actionable versus cosmetic. Ask your buyer's attorney or other Canadian expat owners in the community for inspector recommendations with verifiable recent experience in your target market.

What should I look for in a condo's HOA reserve fund when buying in Mexico?

A condo HOA in Mexico should maintain a reserve fund adequate to cover major common area repairs without requiring emergency special assessments from unit owners. Best practice is a reserve fund equal to at least 3–6 months of total HOA operating expenses — in a well-run development, the reserve fund study (estudio de reservas) projects capital replacement needs for common area assets over a 10–20 year horizon and ensures contributions are matched to depletion rates. In Mexico's beach condo market, where hurricane damage events can generate $100,000–$500,000 in common area repairs, an underfunded reserve is a liability that becomes your liability the moment you close. Request: the current reserve fund balance in USD, the most recent HOA audit or financial summary, and a list of any pending special assessments. If the HOA has no reserve fund study, no independent audit, and a reserve balance below one month of operating expenses, price the risk of a future special assessment into your offer — or walk away. For a $400,000 USD condo unit in a 50-unit building with a $300,000 depleted reserve, your proportional exposure to a major repair event is $6,000+ in special assessments on top of the purchase price.

Property Inspection Checklist for Mexico — What Canadian Buyers Must Check

A property inspection in Mexico covers fundamentally different items than a Canadian home inspection. The critical Mexico-specific checks are: cistern and tinaco water system condition, electrical voltage compatibility (127V standard), flat roof membrane integrity, salt-air foundation corrosion, hurricane-rated glazing and construction, ejido land status, building permit history, and HOA reserve fund adequacy for condos. A professional Mexican inspector costs $200–$500 USD — one of the highest-ROI expenditures in any foreign property transaction.

This guide provides a complete inspection checklist organized by system, with Mexico-specific failure modes Canadian buyers and Canadian home inspectors routinely miss. It covers structural inspection, water and electrical systems, hurricane resistance features, condo-specific HOA checks, ejido verification, title search methodology, and building permit review.

Key Takeaways

A professional property inspection in Mexico costs $200–$500 USD for a standard resale home or condo — one of the highest-value expenditures in a foreign property transaction given the difficulty of warranty claims after closing.
Mexico-specific inspections differ fundamentally from Canadian ones: water pressure, cistern and tinaco (rooftop tank) condition, septic vs municipal sewer connection, 127V single-phase vs 220V transformer access, and hurricane-rated construction are checks your Canadian home inspector has never performed.
Structural inspection priorities in coastal Mexico include: foundation condition (salt air corrosion accelerates rebar deterioration), roof membrane integrity (flat roofs are dominant and fail silently), water infiltration behind tiles, and column-beam connections on upper floors.
For condos, the HOA financial health is as important as the physical condition of the unit — a condo with a $400,000 USD price and a bankrupt HOA is a more dangerous purchase than a structurally imperfect property with a well-funded reserve.
Ejido verification is mandatory on any rural or non-standard property near beach areas — ejido (communal agricultural land) cannot be legally transferred to foreigners, and properties with unresolved ejido complications have been lost entirely by foreign buyers.
A title search (certificado de libertad de gravamen plus a historical title chain review) must be performed by your buyer's attorney before committing — title irregularities caught in due diligence cost nothing; those caught after closing can be catastrophic.
Building permits are a commonly missed due diligence step — construction without a valid licencia de construcción or that deviates significantly from the approved plans is technically an unauthorized structure and can affect your ability to insure, mortgage, or legally renovate the property.
Water infrastructure in coastal Mexico is categorically different from Canadian norms: municipal water supply is intermittent or non-potable in many areas; cisterns and tinacos provide the functional water supply; and septic systems (not sewer) are standard in all but the most urban areas.

Why a Mexico Property Inspection Is Nothing Like a Canadian One

Canadian home inspections are designed for wood-frame construction, forced-air HVAC, potable-from-tap municipal water, 120/240V electrical systems, sloped roofs designed for snow loads, and basements. A typical Canadian home inspection report runs 40–60 pages and covers items that simply do not exist in a Mexican coastal property. Conversely, every building system that dominates Mexican coastal construction — cisterns, tinacos, flat azotea roofs, 127V single-phase electrical, concrete block with column and beam structure, septic fields in tropical soil, and salt-air rebar corrosion — is unfamiliar territory to a Canadian inspector and routinely missed in their reports.

The consequences of a missed inspection in a foreign property transaction are more severe than in Canada. In a Canadian resale transaction, sellers have statutory disclosure obligations, there is title insurance readily available, and you have Canadian legal recourse through courts operating in your language and jurisdiction. In Mexico, disclosure obligations exist in law but are less consistently enforced, title insurance is available but less comprehensive than the Canadian equivalent, and legal recourse for post-closing defect claims is available — in Spanish, through a Mexican court, on a Mexican timeline. The optimal point to identify problems is during the inspection period, before condition removal, when you have full bargaining power and the right to walk away.

Mexican coastal properties fail in predictable, specific ways. A well-maintained property is excellent — Mexico's tropical climate is benign in the absence of humidity-driven infiltration, salt air corrosion, and hurricane damage. The problems that appear in under-maintained or poorly constructed properties are: flat roof failure from pooled water, rebar corrosion in salt air, cistern contamination or pump failure, septic system overload, electrical systems that are overloaded or incorrectly wired, and buildings that were constructed without permits and cannot be legally renovated or insured. Every item on this checklist corresponds to a real, documented failure mode in Mexican coastal real estate.

Structural Inspection Checklist: Foundation, Roof, Walls, and Openings

Structural due diligence in Mexican coastal construction focuses on the intersection of concrete-and-rebar construction with salt air, high humidity, and hurricane wind loads — a combination that accelerates certain failure modes significantly faster than temperate Canadian climates. The following checklist covers the primary structural items your inspector should evaluate.

Structural inspection checklist for Mexican coastal property
Inspection Area	What to Check	Mexico-Specific Concern	Red Flag
Foundation	Visible cracking, settlement, water pooling at base	Salt air accelerates rebar corrosion in concrete; look for rust stains at cracks which indicate active rebar oxidation	Horizontal cracks in foundation walls (indicating lateral pressure); rust bleeding through concrete surface; visible rebar exposure
Roof	Flat roof membrane condition, drain placement, standing water evidence, sealant integrity	Flat roofs (azoteas) dominate Mexican coastal construction — they fail more quickly than sloped roofs and often show no interior evidence of leakage until damage is significant	Blistering or bubbling membrane; pooled water marks; visible cracks in concrete slab; soft or spongy areas underfoot when walking the roof
Columns and beams (upper floors)	Column-beam connections, cracking at column bases, visible corrosion, load path continuity	Coastal construction without adequate concrete cover on rebar shows spalling and delamination; high humidity accelerates oxidation in any visible metal	Spalling concrete exposing rebar at column bases; diagonal cracking at column-beam junctions; uneven floor levels suggesting settlement
Walls and tiles	Tile hollow spots (tap test), grout integrity, moisture behind walls, efflorescence (white salt deposits)	Water infiltration behind wall tiles is a leading cause of structural damage in coastal Mexico and is invisible until tiles are removed	Hollow sound when tiles are tapped (de-bonded); white mineral deposits (efflorescence) at wall bases or grout lines; visible mold on walls or ceiling
Windows and doors	Frame seal integrity, glass condition, operation smoothness, hurricane-rated rating plates	Impact-resistant glass is required by code in Quintana Roo and BCS for new construction; many older and non-compliant properties have standard glass that becomes lethal projectile shrapnel in hurricane conditions	Non-impact glass in a hurricane zone; deteriorated frame sealant showing water staining below windows; frames that bind or won't close fully (indicating foundation settlement)
Stairs and balconies	Railing rigidity, balcony edge sealant, drainage, floor-to-balcony transition	Balcony slab-to-wall junctions are a primary water infiltration point; balcony drains must be clear and functional to prevent pooling that accelerates slab deterioration	Loose or wobbly railings; water staining below balcony edges on exterior; visible cracking at balcony-to-wall junctions; non-functional drains

For Playa del Carmen and the Riviera Maya specifically, the combination of limestone karst geology (highly porous, not a soil type that provides uniform bearing capacity) and frequent construction without full geotechnical investigation means differential settlement is more common than in other markets. Properties built on fill over natural cavities or poorly characterized ground can show ongoing settlement even on 5–10 year old buildings. Your inspector should note any evidence of differential settlement — door frames that are racked, floors that are noticeably uneven, cracks that follow settlement patterns rather than thermal expansion patterns.

Water and Electrical Systems: Mexico-Specific Checks

Water infrastructure and electrical systems in Mexican coastal properties are both categorically different from Canadian standards. Canadian buyers unfamiliar with these systems often make incorrect assumptions — that tap water is potable, that the electrical voltage matches Canadian appliances, or that municipal sewer service is available. These assumptions are wrong in most coastal Mexican markets, and discovering them post-closing creates immediate maintenance problems.

Water and electrical system inspection checklist for Mexican coastal property
System	What to Test	Mexico-Specific Standard	What Good Looks Like
Cistern	Capacity, condition (cracks, biological growth), pump operation, float valve function	Mexico's municipal water is often intermittent or non-potable; the cistern is the property's water reserve, not a backup system — it IS the system	Clean concrete or polyethylene cistern, 10,000+ litres for a full-time residence, functioning submersible pump, working float valve, annual cleaning access
Tinaco (rooftop tank)	Tank condition (UV degradation on polyethylene models), capacity, connecting pipe integrity, screen coverage	The tinaco provides gravity-fed pressure to interior fixtures — low pressure at faucets is almost always tinaco-related, not municipal supply	Polyethylene tinaco in good condition without UV brittleness, properly screened against insects and debris, adequate elevation above fixtures for usable pressure
Water pressure	Run multiple fixtures simultaneously — shower, kitchen tap, toilet fill	In multi-unit buildings, peak-hour pressure drops are common; test at different times of day if possible	Consistent pressure with two fixtures running simultaneously; toilet fill completes in under 5 minutes; shower pressure adequate without electric booster pump
Plumbing pipes	Visible corrosion, pipe material (PVC vs galvanized vs copper), drain slopes, p-trap presence	Older construction may use galvanized steel pipes that corrode from inside; PVC is standard in newer builds and performs well in coastal conditions	PVC or CPVC supply lines with no visible corrosion; functional p-traps at all drains (prevents sewer gas entry); drainage with appropriate slope
Electrical panel	Breaker labeling, amperage capacity, grounding wires, breaker age and condition	127V single-phase is Mexican residential standard; 220V requires either a split-phase upgrade from CFE or a transformer — critical if you plan to operate North American appliances or HVAC equipment	Labeled, organized panel with modern breakers; clear ground wires; no double-tapped breakers; capacity adequate for the property's appliance load
Electrical outlets and wiring	Polarization, grounding (3-prong), visible wiring condition in utility areas	Ungrounded 2-prong outlets are common in older construction — not automatically a hazard, but limits appliance compatibility and is a code violation in newer builds	Grounded 3-prong outlets in kitchen and bathrooms at minimum; no exposed wiring; GFCI protection at wet-area outlets
Septic system (where applicable)	Last pump-out date, tank access cover condition, drain field location and condition	Municipal sewer is unavailable in most of Tulum, large portions of Riviera Maya, rural Jalisco, and most of BCS — septic is the standard; pump-out every 2–4 years is normal maintenance	Documented pump-out within the past 3 years; no sewage smell at ground level near tank; functioning drain field; proper setback from well or cistern

Hurricane Resistance: Checking Construction Compliance in High-Risk Zones

The Caribbean coast of Mexico — including all of Quintana Roo and the northern Yucatán Peninsula — is in one of the most active hurricane zones in the Western Hemisphere. In 2005, Hurricane Wilma caused catastrophic damage to Playa del Carmen and Cancún. Hurricane Delta struck in 2020. Hurricane Beryl made a direct landfall on the Riviera Maya in July 2024. The question for a property buyer in this zone is not whether hurricanes will occur — they will — but whether the specific property is constructed to a standard that survives them with manageable damage.

Compliant modern construction in Quintana Roo should include: reinforced concrete structure with column-and-beam frames; walls of concrete block or monolithic concrete (not wood frame or wood infill); impact-resistant glazing rated to at least 180 km/h wind loads (required by the 2015+ municipal building codes); properly anchored roof slab with hurricane straps at all wall-to-roof connections; and no large unsupported overhangs without adequate hurricane tie-down engineering. Verify with your inspector: are windows single-pane, non-impact glass? Is the roof slab properly tied to the walls? Are there any structural wood elements (a critical vulnerability in a direct hit)? Does the property have a documented construction permit from after the 2015 code upgrades?

For Puerto Vallarta and the Pacific coast, the hurricane risk profile is different — the Pacific hurricane season is active but storms of Cat 3+ making direct landfall on the Jalisco/Nayarit coast are less frequent than Caribbean landfalls. However, Pacific storms have struck Manzanillo, Puerto Vallarta, and Cabo San Lucas in recent decades. The Pacific coast building code is less universally prescriptive on impact glazing, and inspection focus should shift toward seismic resistance — Jalisco is in an active seismic zone where structural integrity checks remain critical.

Condo-Specific Due Diligence: HOA, Reserve Funds, and Common Areas

A condo purchase in Mexico is two investments: the physical unit you can inspect, and the HOA-managed common infrastructure and financial position you cannot see without requesting documentation. The majority of Canadian buyers in Mexico are purchasing condominiums — in beachfront tower developments, boutique low-rise projects, and hotel-branded condo-hotel units. For all of these, the HOA's financial and governance health is a critical diligence item.

Request from the seller or HOA administrator: two years of audited HOA financial statements, the current reserve fund balance and study, a schedule of current maintenance fees and any increases in the past three years, documentation of any pending or recently levied special assessments, the HOA's insurance policy with coverage limits for common areas and the building shell, and the HOA's governing documents (reglamento de condominio). Review the insurance coverage specifically for hurricane events — many Mexican condo HOA policies have coastal exclusions, sublimits, or named-storm deductibles of 2–5% of insured value that can generate enormous out-of-pocket costs after a major storm.

In some Mexican condo developments — particularly those where the original developer retains majority control of HOA governance — the HOA may have been operating without independent financial oversight, with maintenance fees held below market-rate (artificially attractive to buyers) and reserve contributions deliberately underfunded. This creates deferred liability that becomes the buyer community's problem after the developer exits. If the HOA administrator is still the developer or an entity connected to the developer, ask whether an independent management company will be assumed at turnover, and on what timeline. The transition from developer-controlled to owner-controlled HOA governance is a predictable inflection point where underfunded reserves become visible.

Buying a Property in Mexico and Need a Trusted Inspector?

We can connect you with experienced buyer's attorneys and inspectors in Puerto Vallarta, Playa del Carmen, Los Cabos, and beyond — professionals who know exactly what to look for in each market.

Full Inspection and Due Diligence Process: Step by Step

The complete inspection and due diligence process for a Mexican resale property covers physical inspection, legal title review, permit verification, and ejido status checks in a coordinated sequence. Here is the recommended order:

Hire an Independent Inspector Before Removing Conditions

Your purchase agreement should contain a condition allowing you time to complete a physical inspection — typically 10–20 business days in Mexican purchase agreements. Use this period, not after condition removal. An independent inspector in Mexico is not the seller's agent, the developer's agent, or someone recommended by the listing realtor — they work exclusively for you. AMPI-affiliated inspectors (Asociación Mexicana de Profesionales Inmobiliarios) in major markets like Puerto Vallarta, Playa del Carmen, and Los Cabos are the most common starting point for referrals; ask other Canadian buyers in expat forums or your buyer's attorney for inspectors they have used and trust. Inspection cost ($200–$500 USD) is trivially small against the purchase price — there is no reason to skip this step.

Conduct a Water Infrastructure Test on the Day of Inspection

Request that the cistern pump and tinaco system be fully operational on inspection day. Run every faucet, shower, and toilet in the property simultaneously to test pressure under load. Check the cistern for biological growth (green algae indicates the tank needs cleaning or sealing), crack evidence, and float valve function. Inspect the tinaco for UV-related brittleness on polyethylene tanks (surface crazing or discoloration indicates degradation). Ask when the cistern was last cleaned — the answer should be within the past 2 years for a well-maintained property. If the seller or agent says the municipal supply handles everything without the cistern, that is a red flag — it suggests unfamiliarity with the property's actual water supply infrastructure.

Verify Electrical Voltage and Transformer Access

Mexican residential properties run on 127V single-phase power from CFE (Comisión Federal de Electricidad). Most North American appliances and electronics are designed for 120V and work without issue. However, HVAC systems rated for 220–240V (common in Canada) require either a voltage transformer or a CFE upgrade to 220V service — a process that requires a formal CFE application, can take weeks or months, and costs $1,000–$4,000 USD depending on the required infrastructure. Ask your inspector to identify the service entry point and confirm the voltage. If the property has a pool pump, large HVAC unit, or commercial kitchen appliances, confirm these are operating on the correct voltage. A 220V-rated appliance being run on 127V will run poorly, overheat, or fail — and replacing it in Mexico at North American appliance prices is expensive.

Walk the Roof Yourself with the Inspector

Flat roofs (azoteas) are the dominant roof type in Mexican coastal construction, and they are the most common source of major maintenance problems in resale properties. Water that pools on a flat roof due to inadequate drainage, membrane failure, or improperly sealed penetrations infiltrates the slab slowly and silently — by the time ceiling stains appear in the unit below, significant structural damage is often already present. Walk the entire roof surface with your inspector. Look for: pooled water marks (white mineral rings), blistered or separated membrane, cracked or deteriorated sealant around any roof penetration (drainage pipes, electrical conduit, mechanical equipment), and soft or spongy areas that indicate water-saturated concrete. Any evidence of prior membrane repair should be evaluated — patched roofs require understanding of what caused the original failure.

Verify Ejido Status for Any Non-Urban or Waterfront Property

Ejido land — communal agricultural land held collectively under Mexico's agrarian law reform framework — constitutes approximately 53% of Mexico's total territory. Ejido parcels cannot be freely transferred to foreign buyers without a formal conversion process (known as dominio pleno) that transforms ejidal tenure into private titled property. This process requires a vote by the ejido's general assembly and formal registration with the Registro Agrario Nacional. Properties that were developed on ejido land without properly completing this conversion — which includes some beach developments in Tulum and parts of Oaxaca's coast — carry title defects that can result in expropriation or loss of the property entirely. Your buyer's attorney should check the title chain against the Registro Agrario Nacional database before you sign anything. Any property described as having recently converted from ejidal tenure deserves extra scrutiny — verify the conversion is complete, registered, and not subject to ongoing legal challenge by ejido members.

Order a Building Permit Verification

Every constructed element of a property in Mexico requires a valid licencia de construcción (building permit) from the municipal government. Properties that were expanded, renovated, or built without permits — or that deviate significantly from the approved plans — are technically irregular structures. The consequences range from minor (a need to retroactively regularize minor additions) to severe (a mandatory demolition order for structures built in violation of setback requirements, environmental protection zones, or building height limits). Your buyer's attorney should request from the municipal development office the building permit history for the property address and compare it against the physical structure. Additions built after the original construction are particularly common and often unpermitted — a second bedroom added to a palapa, a rooftop terrace enclosed into living space, a bodega converted to a casita rental unit. Each addition needs a permit, and unpermitted square footage technically does not exist in the legal record.

For Condos: Review the HOA Financial Statements Before Proceeding

In any condominium purchase, the HOA's financial health is as material to your investment as the physical condition of the unit. Request: the last two years of audited HOA financial statements, the current reserve fund balance and the HOA's reserve fund study (or lack thereof), any outstanding special assessments passed or pending, the HOA's insurance policy coverage limits, and the current maintenance fee schedule. A reserve fund should hold at minimum 3–6 months of operating expenses — preferably more in hurricane-zone properties where a single storm event can generate $50,000–$500,000 in common area repairs. An HOA that is carrying unpaid common area expenses, has a depleted reserve fund, or has outstanding special assessments that haven't been disclosed is a material issue. In some Mexican condo developments, HOA governance is opaque or dominated by the original developer — verify independently who controls the HOA, how decisions are made, and whether annual meetings are held.

Title Search and Boundary Survey: The Legal Due Diligence Your Inspection Cannot Cover

A physical property inspection establishes the condition of the structure. It cannot establish whether the property's title is clean, its boundaries are accurately described, or whether there are competing claims, unregistered liens, or legal encumbrances that will become your problem after closing. These are legal due diligence items performed by your buyer's attorney, not your inspector.

The minimum title review package for a Mexican property purchase includes: (1) a current certificado de libertad de gravamen from the Registro Público de la Propiedad confirming no registered liens or encumbrances, (2) a title chain review going back at minimum 30 years or to the property's original agrarian or government grant, (3) a search of the Registro Agrario Nacional for any ejidal tenure history, and (4) a boundary survey by a registered DRO surveyor confirming that the physical property footprint matches the legal description in the title deed. Boundary disputes with adjacent properties are a persistent source of litigation in Mexican real estate — particularly in coastal areas where original survey monuments may have been destroyed by construction or storm events. A formal boundary survey ($500–$1,500 USD) is inexpensive insurance against a boundary dispute that can take years to resolve.
