Whether you're buying a house or looking to become an inspector, it pays to know exactly what an inspection covers — and what it doesn't. This guide walks through, system by system, what a competent inspector checks in a Mexican property.
Why Mexico needs its own checklist
Mexican construction is different: block and concrete walls, flat waterproofed rooftops, virtually no basements, water stored in a cistern and pumped up to a rooftop tank, LP gas instead of natural gas, and a climate — especially on the coast — that accelerates corrosion, salt damage, and moisture. A checklist copied from the US checks things that don't exist here and skips exactly the ones that fail most. That's why a serious inspector works from a checklist adapted to Mexico.
The systems an inspection covers
Structure and foundation
Cracks, settlement, the condition of slabs, beams, and load-bearing walls. The inspector distinguishes a cosmetic crack from a structural one and, when in doubt, recommends a structural engineer's opinion.
Rooftop and waterproofing
The flat rooftop is one of the most failure-prone points in Mexico. The inspector checks the waterproofing membrane, slopes, drains, and any sign of water intrusion into the levels below.
Water system: cistern, rooftop tank, and pump
Storage (cistern), elevation (rooftop tank), pressurization (pump or pressure system), leaks, and pressure at taps and showers. The water heater — tankless or storage (boiler) — and its installation are checked too.
LP gas
Stationary tank or cylinders, regulator, hoses, connections, ventilation, and signs of a leak. A gas installation in poor condition is one of the most serious safety findings.
Electrical
Panel and capacity, the CFE service connection, polarity and grounding, wiring condition, and protection (GFCI) in wet areas like bathrooms and the kitchen.
Plumbing and drainage
Pipes, pressure, drains, leaks under sinks, toilet operation, and — where applicable — septic systems.
Interiors, windows, and climate
Floors, ceilings, doors, aluminum window frames and seals, plus climate units (mini-splits): power-on and general condition.
Moisture, salt damage, mold, and pests
Rising damp (the salt that climbs up walls), leaks, mold, and pests such as termites (comején) — especially relevant in hot, coastal climates.
Exteriors and surroundings
Perimeter walls, site drainage, the carport, and — if the property has one — the pool and its visible equipment.
What an inspector should flag (beyond the physical)
An inspector doesn't perform an appraisal or give legal advice, but should raise flags so the buyer can verify them with the right specialist:
- Hidden defects (vicios ocultos): non-apparent defects worth documenting.
- In coastal areas: property held under a fideicomiso and ZOFEMAT (federal maritime-terrestrial zone) restrictions.
- Ejido risk and construction permits worth confirming.
The inspector documents what they observe and recommends confirming it with a notary or an expert as needed. For rental properties, that same condition record is the basis of a solid move-in/move-out inventory.
What an inspection is NOT
- It's not a guarantee that nothing will fail later.
- It's not destructive: the inspector doesn't open walls or lift floors.
- It doesn't certify building-code compliance — there's no uniform national residential code in Mexico.
- It's not an appraisal (that determines value, not condition).
Setting these expectations with the client up front is part of a professional service.
What a good report looks like
All of the above only matters if it's documented clearly. InspectoMX comes with a Mexico-specific checklist — cistern, rooftop tank, LP gas, moisture, termites, coastal flags — and turns your findings into a professional, bilingual, photo-documented PDF, ready to deliver under your own brand. You can see sample reports to know the deliverable.

How long does a home inspection take?
It depends on the size and complexity of the property, but a typical house or condo inspection takes 2 to 4 hours on site, plus the time to produce the report.
What does a home inspection NOT include?
It doesn't include destructive testing (no opening walls or lifting floors), it isn't an appraisal, it doesn't certify compliance with a building code, and it isn't a guarantee that nothing will fail in the future. It's a visual assessment of condition on the inspection date.
Does the inspection detect termites?
The inspector documents visible signs of termites, moisture, and mold, and recommends a pest-control specialist for treatment. It doesn't perform fumigation or a specialized pest report.
What is a hidden defect (vicio oculto)?
It's a defect that wasn't visible at the time of purchase and that, had it been known, would have changed the decision or the price. An inspection report with dated photos is your best evidence of the condition in which the property was handed over.
