Fee schedule

Building permit fee
This guide does NOT print Mount Vernon's per-bracket building permit fees. Show full citationThis guide does NOT print Mount Vernon's per-bracket building permit fees. The city publishes them as a table whose valuation brackets and fee amounts do not stay aligned when the document is read mechanically — the amount beside a bracket can belong to a different bracket. Rather than print a real number against the wrong valuation band, the fee authority is named here and the schedule should be read directly: the Development Services Fees schedule published by the Development Services Department.
