Why an engineer writes these
Most property advice in Puerto Rico comes from people selling the transaction. As a licensed professional engineer, I write from the other side of the table: what holds up a building, what the permit record actually says, what a flood map means for your insurance, and where the boundary really sits.
The buyers who reach me fall into two camps. Some are diaspora families and stateside investors who cannot walk the property on a Tuesday afternoon. Others are local buyers who know the island but want a technical read before they commit. Both run into the same trap: a house can look freshly painted and move-in ready, yet still be undocumented, structurally compromised, in a high-risk zone, or sitting on a lot whose boundaries do not match the deed. "Looks fine" is not the same as sound, legal, permitted, and insurable. These guides exist to close that gap before you sign.
The guide index
Start here
The full picture in one place: how structure, permits, flood risk, and boundaries fit together, and how engineering due diligence works alongside your attorney, notary, and lender. Read this first, then go deep on whatever applies.
Permits
How to tell whether a home and its additions were ever legally permitted, why an undocumented structure can stall financing or insurance, and what an engineer looks for in the OGPe record.
Hazards
What makes a house resilient to the island's real hazards. The 2018 Puerto Rico Building Code sets coastal design winds in the range of roughly 145 to 170 mph, and the southwest faults are active. What to read in the framing, connections, and foundation.
Flood
How to read a flood map, what a high-risk zone means for required insurance and buildability, and the engineering questions to ask before the flood zone becomes your problem.
Title
The difference between the cadastre (the tax and ID record), a real survey or mensura, and clear title, and why the boundaries on the ground sometimes do not match the paperwork. Where the engineer's work ends and your attorney or notary's begins.
Prefab
Puerto Rico has a statute written for prefabricated houses, and it gives the buyer real rights: an engineer-certified construction plan, a seller liable for its defects, and a permit obtained before you acquire the unit. What to demand before you pay.
Done reading? Get a property-specific read
The guides above are general. This is the service itself: a licensed structural assessment and records check on your specific property before you close, with a written go, conditions, or no-go you can act on.
Talk it through
Reading is the start. The next step is a property-specific read from someone who has stood in hundreds of Puerto Rico homes, before a purchase that looks fine and is not.
