Understanding Building Safety in San Francisco
San Francisco has 206,181 buildings in our database, scored from 0 to 100 based on government violation records. The average safety score is 80/100, with 100% of buildings having at least one violation on record. This is relatively good — most buildings maintain acceptable safety standards.
Before signing a lease in San Francisco, we recommend checking your potential building's safety score. Buildings with scores below 50 may have unresolved structural, fire safety, or habitability issues. Open violations are especially important — they indicate problems that have been officially documented but not yet fixed by the landlord.
What do the scores mean?
- 80–100: Excellent — minimal or no violations, well-maintained building
- 60–79: Good — some past violations but generally resolved promptly
- 40–59: Fair — multiple violations, some may still be open
- Below 40: Poor — significant unresolved safety concerns, proceed with caution
