Tips
- If you're building a shed or garage before your main house, the accessory structure's building permit is issued together with the principal structure's permit, and its final inspection waits until the principal structure passes rough framing inspection.
- Retaining walls are capped at 8 feet in height and fences in residential zones at 6 feet above natural grade per the Zoning Regulations' Standards of General Applicability — confirm any taller structure with the Building Division before applying.
- Call 811 before digging to locate underground utility lines; fences with gates/removable sections may cross municipal utility easements only with written Public Works Director approval.
