The Permit Process
Step 1: Pre-Application (1-4 weeks)
- Research zoning requirements
- Confirm property is eligible for proposed use
- Meet with building department (recommended)
- Identify any special requirements (wetlands, historic, HOA)
Step 2: Plan Submission (1-2 weeks preparation)
- Complete architectural and engineering plans
- Prepare site plans showing setbacks and utilities
- Compile all required documentation
- Submit application with fees
Step 3: Plan Review (2-12 weeks)
This is typically the longest step. The building department reviews plans for compliance with:
- Building codes (structural, fire, energy)
- Zoning requirements (setbacks, height, lot coverage)
- Environmental regulations
- Accessibility requirements
- Utility capacity
Step 4: Revisions (1-4 weeks if needed)
If the plan reviewer identifies issues, plans must be revised and resubmitted. This can add significant time if revisions are substantial.
Step 5: Permit Issuance (1-2 weeks)
Once plans are approved, the permit is issued and construction can begin.
Step 6: Construction Inspections (ongoing)
During construction, inspections are required at key milestones:
- Foundation
- Framing
- Mechanical rough-in (plumbing, electrical, HVAC)
- Insulation
- Final inspection
