Coverage grows as we mine the archive. Six Bay Area cities today — more every month.

Predicted corrections

Predictions are drawn from anonymized patterns in 15+ years of issued permits and correction letters — they flag what reviewers usually catch, not a guarantee of what they'll catch on your set. The $95 Pre-Flight Check puts a human on your actual plans before filing.

Why this exists

Every permit shop files and hopes. We file knowing — because we've read the correction letters. Oakland's 4LEAF reviewers send formal Comments-and-Conditions packages. SFFD redlines plan sheets in clouds. Berkeley runs a two-document system most filers don't expect. The Pass Predictor turns those patterns into your pre-flight list.

Built from our permit archive: 241 approved job folders, 2,000+ plan sets, and correction artifacts across 15+ Bay Area jurisdictions. Only aggregated, anonymized patterns ever leave the building.
