01 — Survey

Before you build, know the rules.

A backyard is a legal drawing before it is a lifestyle photo. Height, setbacks, and a permit question sit on the lot — whether you sketch them or not.

02 — Program

What are you building?

Hover a project. The lot highlights the structure. Every card is a path into typical rules, cost bands, and a calculator — not a legal opinion.

03 — Permit checker

Do I need a permit?

Pick a project and a state. You will get a typical pattern — not a yes stamped by a clerk. City pages exist so we can attach sources as they are verified.

Unit

per linear foot

Often none for a standard-height rear/side fence; often yes for taller fences, front-yard fences, or work in easements. Always verify.

California cities tend to be specific about fence height in front yards, accessory-dwelling rules, and wildfire-adjacent building. State ADU law overlays local zoning — it does not erase building permits.

05 — Visual calculator

Change the fence. Watch the takeoff.

Length and height drive posts, panels, and bagged concrete. Cost is a labeled national band — not a contractor’s bid.

06 — Location

Rules vary by location.

State → county → city. These pages hold patterns and a place to attach building-department sources as they are verified. Nothing here is your permit.

09 — Methodology

Trust, on purpose.

Regulations

We describe typical U.S. patterns and keep a slot for city, county, and code citations. Unverified numbers stay labeled as patterns.

Costs

Ranges are 2026 national bands from published contractor-cost literature and takeoff math — not a quote for your lot.

Calculations

Volume, posts, joists, board feet: dimensional formulas with visible assumptions. You can edit spacing, waste, and depth.

Updates

Each guide carries a last-reviewed date. Location pages are built to accept a source URL and a verification stamp.

Read the methodology

Requirements vary by jurisdiction and by the specifics of a project. YardPermit publishes educational patterns and labeled estimates — not legal determinations, not construction documents, and not a bid. Verify with your local building department and a licensed contractor before you build.

10 — Begin

Build with fewer surprises.

Start with dimensions and choices. Leave with a takeoff, a permit-question list, and one scope every contractor can price.
