Buffalo ADU Permit Fees & Cost Calculator
Buffalo has a city fee schedule for building permits, but the publicly available result set does not expose a clear ADU-specific fee table. The most relevant official source confirms building permit fees exist and directs applicants to the Permit Office for details, while a secondary guide suggests ADU permit fees are commonly calculated from project value and may range widely; exact ADU fee amounts should be verified with the city.[4][1]
