Home scores

Compare the environmental and school district data around a home.

Scoring grid Unconfirmed

Street address + city; ZIP is optional. California only. Submit to send this address through HomeScore's Cloudflare service to Geocodio for location matching. Addresses are not sent to Google Analytics.

Location accuracy

Geocodio may return an address point or estimate a location along a street. If a house number cannot be matched, one additional city or ZIP lookup may locate its area. The area-center pin is clearly labeled and does not load a home score; select the actual home on the map to see nearby grid scores. Neighboring-home matches are not accepted. New homes may be missing. Scores describe a nearby 100 m grid point, not a measurement of the home. Geocodio may retain lookup logs for up to 45 days.

About the scores and their limits

HomeScore turns environmental and school district data around a home into reference scores for early-stage comparisons. It does not certify a home's condition, market value or safety, and is not an individual property investigation.

Los Angeles Metropolitan Area is our navigation label for Los Angeles, Orange, Riverside, San Bernardino and Ventura counties, not an official statistical boundary. San Diego Metropolitan Area covers San Diego County. San Francisco Bay Area covers Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano and Sonoma counties. Region and county selection move the map; all 15 counties remain visible, with aggregated scores at wider zoom levels. The basemap may include places outside these counties. Grid sample points are not homes or parcel boundaries.

Each layer is colored only when that individual score is determined. Uncolored areas have incomplete data or no coverage, not a high score; you can still select them to see what is missing.

San Diego has flood-data gaps, including FEMA Zone D; unknown areas stay uncolored in the flood layer. U.S. and California facility sources do not establish complete coverage of facilities in Mexico.

Current rules: v4.3, updated September 26, 2026. The 15 counties use 100 m grid sample points; wider views show averages of saved point scores. The 100 m spacing is a calculation interval, not property-assessment accuracy.

Aviation facilities are grouped by FAA/BTS type. H heliports (including helipads) use distance anchors of 100 / 300 / 500 / 1,000 m; airports and other or unknown types use 1,000 / 3,000 / 5,000 / 10,000 m. Both correspond to 25 / 50 / 75 / 100 points. Each group uses its nearest distance, rounded up to a whole meter with linear interpolation; the lower group score applies. Missing evidence in either group retains an uncertain range. The 1 km and 10 km limits are scoring cutoffs, not noise boundaries or safe distances. Flight paths, schedules and operating frequency are not included.

Mean ELA and math proficiency is the school district score: the mean of the two official 2024–25 CAASPP proficiency rates. It drives the individual score and school layer. Where elementary and high school districts differ, the lower mean applies; incomplete data remains unknown. Same-type statewide percentiles are reference only, not part of scoring. These are district-wide results, not individual school scores, school-fit measures or enrollment guarantees.
