Climate
Tropical lowlands, wetter Caribbean areas and cooler uplands create very different building conditions. Many Pacific areas have a pronounced wet and dry season; exposure changes with elevation and terrain.
Geographic hazards
- Earthquakes & volcanic areas
Check seismic design and locally relevant volcanic hazards. Older unreinforced masonry, unsupported additions and weak structural connections need professional review.
- Heavy rain, flooding & landslides
Steep plots, cuts into hillsides and river corridors require careful drainage and geotechnical checks. Confirm wet-season access as well as the building platform.
- Coastal flooding & tsunami exposure
Use local coastal hazard and evacuation information. A sea view does not compensate for unsafe elevation, erosion or an exposed access route.
- Storm rainfall, heat & dry-season fire
Tropical weather systems can cause heavy rain even without a direct hurricane landfall. Drier areas also need shade, water planning and local wildfire checks.
Insects and rot
In warm, humid locations, ask specifically about termites and timber-boring insects. Roof leaks, wet end-grain, soil contact and poorly ventilated concealed spaces can lead to decay. Upland and coastal exposure should not be treated as identical.
Best-fit building approaches
- Engineered concrete & reinforced masonry
Ductile reinforced concrete or properly designed reinforced masonry can be suitable when seismic detailing, foundations and quality control are verified. Avoid equating unreinforced block walls with an engineered system.
Read the concrete & block guide - Engineered timber framing
A lighter, well-engineered frame can be suitable with seismic connections, local pest protection and a ventilated, rain-resistant envelope. Confirm local approval and reliable workmanship.

Buyer checks
Review seismic design, alterations and permit records with a local engineer.
Investigate slope, drainage and access in the wet season.
Check coastal or volcanic hazard zones and commission a pest/moisture inspection.

Print or save as PDF using your browser. Includes country guidance, official links and blank spaces for handwritten notes. No property details are saved.
These official resources help you ask better questions; they do not provide a parcel-level risk assessment. A map does not guarantee safety, and an unmapped or blank area does not mean no hazard. We do not assign automatic property risk scores.
- Collect the address, region/municipality, cadastral parcel reference and coordinates from the seller or surveyor. Check the map pin against the actual plot, not just the postcode or village centre.
- Open the relevant resource below. Where there is no address search, use coordinates, local landmarks or the named regional map sheet. Check the plot, access roads and evacuation routes.
- Read the legend, scale, publication date, model scenario and coverage. A “100-year” event is a probability scenario, not a promise of one event per century. Check current official warnings separately before visiting.
- Ask the responsible authority for the latest local study and restrictions. Give the findings to a qualified surveyor, structural/geotechnical engineer and insurer before relying on them in a purchase.

CNE — provincial and cantonal hazard maps
Authority: Comisión Nacional de Prevención de Riesgos y Atención de Emergencias, Costa Rica
Hazards: Flooding, landslides, seismic and volcanic hazards as shown in each canton
Coverage: Costa Rica; choose province, then canton.
How to locate the property: Select the province and canton, open its map and explanatory text, and locate the district, settlement, rivers and slopes around the parcel. Give the municipality the cadastral plan and coordinates for a local check.
Limits: CNE calls these preliminary maps, mostly based on 1:50,000 or broader sources. Blank areas can reflect missing data; the maps must not replace detailed technical studies or be enlarged into parcel boundaries.
Editorial review: 2026-10-14. Published edition [not-recorded]: Edition or layer dates were not recorded in the initial research; verify with the publisher. This is not a live status or property assessment.
Confirm locally — including gaps in mapping
Ask the municipal planning office and local emergency committee/CNE for current land-use restrictions, flood and slope studies, coastal/tsunami routes and relevant volcanic advice. No complete public parcel-level wildfire or cyclone/coastal map was verified here; ask the municipality and fire service about local vegetation, storm runoff and safe access.
