Tips
- The Building Addition Permit Application requires only a $50.00 minimum deposit, versus $200 for new residential construction.
- Like-for-like replacement of hardwired electrical, plumbing, or mechanical systems/appliances in a single-family or 2-family home is a flat $30 permit, regardless of the standard valuation-based fee formula.
- Repairs using similar materials for maintenance only (painting, floor coverings, cabinetry, storm doors/windows) do not require a permit at all, per § 18.15.040 — but this exemption does not cover design changes or new fixtures/equipment.
