Pulling the parcel record, FEMA flood zone, USGS seismic + terrain, USFS wildfire, EPA radon and zoning standards. First run on an address takes up to 30 seconds — after that it's cached.
Zoning coverage: This jurisdiction publishes its zoning in a source we can’t read yet — the district identity (R-1A) is here, the dimensional standards are not.

12435 West Castlewood Drive, Boise, Idaho 83709, United States carries a Buildability Score of 92 out of 100 (grade A+). The score is composed from 7 weighted factors — each cited to its federal or jurisdictional source and re-runnable live on this page.
Grade A+ reads as a scored buildability read across zoning, flood, seismic, soil, radon, wildfire, and utility factors. The grade is derived from the numeric score (92/100) on the published Buildability™ scale.
The weakest factor at this address is radon (scored 75). That's the factor most likely to constrain what a design can carry, and the one to inspect first before committing capital.
Flood scores 95 out of 100 — the highest of the 7 factors read for this address.
Every factor cites the federal or jurisdictional dataset it came from — FEMA (flood), USGS (seismic), USFS (wildfire), EPA (radon), USDA/NRCS (soil), and the local jurisdiction's own zoning record where available. Sources are queried live and re-run on refresh; the score cannot outrun its data.
When Ada County, ID's zoning record is on our roster, the score reads the jurisdiction's own dimensional standards for the district this parcel sits in. When it isn't, the zoning factor drops out rather than being estimated — which is why parcels in un-rostered jurisdictions still return a score, just one that doesn't count zoning.
No. The Buildability Score™ is a preliminary due-diligence read, not an entitlement or permit approval. Governing bodies retain sole authority over binding land-use decisions. The score's role is to make the diligence conversation faster and better-grounded, not to replace it.
