Mount Vernon, NY Building Safety: Building Permits (2026)

L. No. 6-2024), bars starting any Uniform Code or Energy Code work, including construction, enlargement, alteration, improvement, removal, relocation or demolition of a building, or installing a solid-fuel-burning heating appliance, chimney or flue, without first getting a building permit from the City. Listed exemptions cover one-story detached tool sheds and playhouses under 144 square feet, temporary movie or theater sets, window awnings on one- and two-family homes, partitions or movable cases under five feet nine inches tall, interior painting and plastering, and listed portable electrical, plumbing or HVAC equipment; an exemption never authorizes work that otherwise violates the Codes.

Applications go to the Code Enforcement Officer in writing and, for most projects, must include a topographical survey, plot plan showing setbacks and drainage, a description of the work, the Tax Map number, occupancy classification, and construction documents sealed by a licensed architect or engineer. A building permit must be displayed at the work site, and all work must follow the accepted construction documents; any change requires immediate notice to the Code Enforcement Officer and may require an amended permit. Under Section 102-4J, a permit becomes invalid if work is not started within 12 months and expires 12 months after issuance, though it can be renewed on application and payment of the fee set under Section 102-18.

The Code Enforcement Officer can revoke or suspend a permit issued in error or where the work violates the Uniform Code or Energy Code, under Section 102-4K.
