Permit Timelines by Structure Type

|---|---|
| Agricultural Barn | 6–12 weeks(when clearly ag-use) |
| Residential Accessory Structure | 8–16 weeks |
| Estate Pavilion / Assembly Structure | 4–10 months |
| Winery / Ag-Tourism Structures | 6–12+ months |
Timeline expansion is usually driven by use classification, Fire Marshal review, septic coordination, overlays, or site plan requirements.
