NATIONWIDE PRELIMINARY PLANNING
Know what to check before you build.
Build a practical starting checklist for your project. PermitPreflight helps homeowners and contractors identify common approvals, documents, and local offices to contact before work begins.

Tell us a little about the project.
Important: Nationwide access does not mean every local rule has been verified. Requirements vary by city, county, zoning district, property, and project details. Confirm requirements with the local building and zoning offices before relying on this checklist.
What PermitPreflight does
A clearer first step—not a substitute for the authority having jurisdiction.
- Organizes common permit and zoning questions.
- Helps you prepare before contacting a local office.
- Creates a printable project checklist.
- Separates general planning guidance from locally verified requirements.
We do not currently perform parcel lookups, issue permits, or certify that a project is permit-exempt. Always obtain written guidance from the responsible local authority.
Your preliminary checklist
This is a general planning checklist, not a determination of legal requirements. Ask the local building department and zoning office to confirm what applies to your exact property and scope of work.
