Tent Permit Guide: Common Questions

Do I need a permit for my event tent?

It depends on your city and fire department. Rules vary a lot from place to place. In California, a common trigger under the California Fire Code (2025 CFC Section 3103.2) is a tent over 400 sq ft. Canopies open on all sides get more room, up to 700 sq ft, if they meet the spacing rules. Many cities add their own triggers too, like cooking, generators, food trucks, crowd size, or a special event permit. The safest move is to check with your local fire department. If you start a plan with me, I'll check your fire department's requirements.

What size tent needs a permit?

There's no single answer for everywhere. In California the 400 sq ft and 700 sq ft numbers above come up a lot. A 20x20 is exactly 400 sq ft, so anything bigger usually gets a look. Some fire departments are stricter, and some count several small pop-ups together. Outside California, your local fire code and fire department decide.

What does a fire department want to see in a tent site plan?

Usually a drawing of the site showing:

Bigger tents or bigger crowds can also need a floor plan with seating and exits. Some departments ask for proof the tent is anchored and stable, too. Each department has its own checklist.

What's the difference between a stamped engineered plan and a non-engineered site plan?

Both are based on your jurisdiction's requirements. A stamped plan is also built to engineering requirements, and it's prepared and signed by a licensed engineer. It can cover things like anchoring, wind load, and structural stability. Some fire departments require one, usually for larger tents or when they ask for structural documents. A non-engineered site plan is a clear, accurate layout drawing with no stamp. Plenty of fire departments only need the layout. If yours doesn't ask for a stamp, the simpler plan can save you money. Not every city requires a stamp. When one isn't required, a stamped plan can still help, since fire departments tend to review and approve stamped plans more readily. If your city does require a stamp, you'll need the engineered plan.

What do you offer and what does it cost?

Both are based on your jurisdiction's requirements, and either way, you see a draft of your plans with your exact price before you pay.

How long does it take?

Either plan, stamped engineered or the $149 non-engineered site plan, usually takes 1 to 2 business days. Leave yourself time for the fire department too. Their review can take a while, and many departments want your application a week or two before the event, sometimes more. Check your department's deadline early.

Can you help me file the permit?

Yes. Filing help with the fire department is an add-on, and I'll quote it for your job. Or you can take the plans and submit them yourself.

What if the fire department comes back with comments?

On the $149 unstamped site plan, one map revision after fire department comments is free. If the comments call for calcs or engineering, that goes beyond a site plan, and we'd talk about a stamped plan (California) or an engineer in your state. Stamped plans include one revision.

Do you work outside California?

The unstamped site plans, yes, in any state. Stamped engineered plans are California only for now.

Who's behind X Marks the Site?

I'm a California-licensed civil engineer (PE) with 10+ years of civil engineering experience. Before that I spent 10+ years in the party and tent rental business installing tents, so I know how tents actually go up.
