Speeds up housing approvals. Cities and counties must approve infill housing administratively if it matches nearby density and current standards—no rezoning or public hearings—and treat it as conforming. They can’t deny or delay housing for being incompatible when next to other housing. Limits design rules for single/two-family homes with narrow exceptions for older local boards. Bans value-based fees; review fees must reflect actual, itemized costs. Likely more homes, less red tape.
