Tips
- Per the City's published Plan Review Timeline, 'Single Family Residential and Duplexes - Remodel' averages 15 business days for the first review round and 7 business days for additional rounds — the same timeline as new single-family construction.
- Decks under 30 inches high, under 200 sq ft, not part of required egress, and detached from the house are the narrowest category still requiring a permit per the City's 'What Needs a Permit' matrix — there is no fully permit-exempt residential addition/deck category in Prescott.
- Historic Preservation District properties (13 Local and 13 National Districts citywide) may require additional review for work affecting exterior appearance.
