Zoning Certificate Requirement
Before a building permit is issued, applicants must secure zoning approval from their township or municipality. Without a zoning certificate, the building division cannot release a construction permit.
Local Zoning Approval Process
Zoning officials verify property setbacks, land use compliance, lot coverage limits, and height restrictions. Projects involving floodplains, stormwater drainage, sewer access, or water availability may require additional clearance from MSD or GCWW before final approval.
When a Building Permit Is Required
Permits are mandatory for most structural construction and major alterations. Beginning work without approval may result in penalties, stop-work orders, or increased inspection costs.
Projects That Require Permits
- New residential buildings
- New commercial buildings
- Structural additions
- Basement finishing
- Detached garages and carports
- Decks and porches
- Swimming pools
- Major structural repairs
Minor maintenance such as siding replacement or same-size window replacement typically does not require a permit.
Building Permit Fees and Cost Structure
Permit costs vary based on project size, square footage, and type of construction. Fees include multiple components regulated by county and state requirements.
Fee Breakdown Table

|---|---|
| Upfront Application Fee | Paid at submission; varies by permit type |
