ALL BUILDING PROJECTS REQUIRE A PERMIT* (i.e., new construction, remodeling, deck, etc.) EXCEPT for small projects and repairs with a value of less than $500.00. The building inspector is responsible for issuing building permits and overseeing the construction of all phases of projects being done within the city limits. See Quick Links for more information on the inspectors covering projects located in the Town of Hudson, Town of Troy, Town of St. Joseph, and the Village of North Hudson.
The city uses a combination permit system with one permit issued per project to include all work associated with the project. The building, electrical, plumbing, mechanical, structural, etc., will share the same building permit.
All payments for permits must be CASH OR CHECK ONLY; the city can not accept any credit/debit cards.
An application with all supporting documents can be dropped off at city hall (505 3rd Street), mailed, or emailed directly to the inspector. A minimum of 2-3 days for processing is standard. Additional days may be necessary for complex projects or periods of heavy workloads. Once processed and approved, the applicant will be contacted. The applicant must come to city hall during business hours (8 a.m. to 4:30 p.m. Monday through Friday) to sign the building permit and make payment (cash or check only) before any work is started**.
*New or replacement roofing, siding, and/or same size window/door DO NOT require a building permit if there are no structural changes/repairs.
**Projects started before issuance and permit pickup are subject to additional fees.
