No verified online portal was located in the reviewed public materials. Contact 315-785-5130 and request the current application route before preparing a final submittal.
How long might review take?
N/A; no standard plan-review interval is published.
How are inspections scheduled?
Submit the completed building-permit application, construction specifications, plot plan, construction plans, and local zoning permit to 175 Arsenal Street. The County performs plan review, issues permits, conducts construction and fire-safety inspections, and issues certificates of occupancy for municipalities it serves.
Which codes and exemptions should I review?
Jefferson County enforces the New York State Uniform Fire Prevention and Building Code in 31 municipalities that chose not to enforce it locally. The applicable program uses the 2025 New York State Uniform Fire Prevention and Building Code and 2025 Energy Conservation Construction Code, effective December 31, 2025, with local zoning and any municipal standards; some municipalities retain their own code offices. County materials state that most new residential and commercial construction, alterations, conversions, and renovations require permits. Limited Uniform Code exemptions may apply to ordinary nonstructural repairs and specified minor work; confirm with the County Code Office before starting.
