Earthquake faults
Every mapped fault near the address from the U.S. Geological Survey fault database, drawn on a map, with the nearest faults named and the distance to each.
Home hazard report by address
How close is the nearest earthquake fault?
Send an address. APEX Engineering returns a report of the natural hazards at that home: the earthquake faults nearby and how far away they are, the seismic shaking the site is designed for, liquefaction, landslide and tsunami zones, wind, snow, flood zone and soils, with aerial and street views. Prepared by a licensed structural engineer from the same public hazard data used to design buildings.

The report
Nine sections, one address.
Each hazard is mapped, its value for the address is stated, and its source is named, in one PDF.
Seismic shaking
ASCE 7-22 ground motion for the address: Ss, S1, SDS, SD1 and the seismic design category, the values used to design new construction there.
Liquefaction and landslide
Whether the address is inside a mapped liquefaction or landslide zone, where the state has mapped them.
Tsunami
Whether the address is inside a mapped tsunami hazard area on the coast, where the state has mapped one.
Wind and tornado
Basic wind speed, exposure from the land cover around the site, the hill effect from ground profiles in eight directions, and tornado data.
Snow and ice
Ground snow load and ice thickness for the address and its elevation.
Flood zone
The FEMA flood zone at the address and the flood map around the home.
Soils
The mapped soil under the home from the national soil survey, including shrink-swell clay where it is mapped.
Aerials and street views
Aerial views from four directions and from above, and street views of the property.
Who orders it
Before you buy, build or insure.
Home buyers
Know what is under the home and nearby before the contingency period ends.
Homeowners
Understand the earthquake, flood and wind exposure of the home you own, for retrofit and insurance decisions.
Builders and designers
Design values for an ADU, addition, solar array or new home, stamped where the permit calls for it.
Agents and lenders
A clear, engineer-prepared summary to hand a client with a disclosure packet.
Pricing
One report, one price.
Home Hazard Report
$150
- All nine sections, mapped and stated for the address, with aerial and street views of the property.
- Sealed and signed by a licensed Professional Engineer, with the design wind, snow and seismic values certified for the address.
- Its own report number, so a call about the house picks up where the report leaves off.
- One PDF by email.
Where the seal applies
- Sealed in Arizona, California, Colorado, Florida, Nevada, New York, Oregon, Texas and Washington.
- Any other U.S. address: the same report, issued without the seal, at the same price.
- A specific concern about the structure is addressed separately; call (408) 379-2068 with the report number.
Scope. The report is an engineer's summary of published hazard data for the address. It is not a site visit, a home inspection, a structural evaluation of the home or a geotechnical investigation, and it is not a California Natural Hazard Disclosure statement. Zones are reported where a public agency has mapped them.
Questions
Common questions.
Is my house near an earthquake fault?
The report maps every fault in the U.S. Geological Survey Quaternary Fault and Fold Database within reach of the address, names the nearest faults and gives the distance from the home to each one.
What seismic design category is my address in?
The report lists the ASCE 7-22 ground motion values for the address (Ss, S1, SDS and SD1) and the seismic design category that follows from them, the same values an engineer uses to design a new building there.
Is the home in a liquefaction, landslide or tsunami zone?
Where a state has mapped these zones, the report states whether the address is inside one. California maps them through the California Geological Survey; where a state has not mapped a zone, the report says so.
What wind speed and snow load apply to my address?
The report gives the basic wind speed, the wind exposure worked out from the land cover around the site, the hill effect (topographic factor) from ground profiles in eight directions, the tornado data, the ground snow load and the ice thickness.
Is the home in a flood zone?
The report shows the FEMA flood zone at the address and the flood map around it.
Is this a home inspection or a soils report?
No. The report is an engineer's summary of published hazard data for the address. It is not a site visit, a home inspection, a structural evaluation or a geotechnical investigation, and it is not a California Natural Hazard Disclosure statement.
Is the report sealed by an engineer?
Yes. The report is sealed and signed by a licensed Professional Engineer in Arizona, California, Colorado, Florida, Nevada, New York, Oregon, Texas and Washington, with the design wind, snow and seismic values certified for the address. In other states it is issued without the seal.
What if I have a concern about my house itself?
Every report carries its own report number. Call APEX Engineering at (408) 379-2068 with the report number in hand to have a specific concern about the structure addressed.
