Permit checkpoints

  • Set your state for localized rules

    Permit thresholds, frost-line depth, and fence-height caps vary a lot by state. Pick your state above to tailor this checklist.

  • Call 811 before digging footings

    Free U.S. utility locate. Required before setting concrete post holes. Schedule 3 business days out.

  • Check property line setbacks

    Pergolas are structures — most cities require the same 5–10ft setbacks as sheds. Confirm before locating your corners.

  • HOA / neighborhood approval

    Many HOAs restrict outdoor structures. Get written approval before ordering lumber.

  • Confirm the residential-accessory exemption

    120 sq ft pergolas often fall under the accessory-structure exemption, but always verify — a 5-minute call to the building department.

  • Required approvals to line up

    • Zoning setback approval • Building permit if over 200 sqft or 10 ft tall • HOA architectural approval Call your local building department to confirm which of these apply in your jurisdiction — requirements vary city to city.

Rules vary by city and county — always confirm with your local building department. Estimates only, not a permit determination.
