Do You Need a Permit for Your Business Sign? A Small Business Primer
In most US cities you need a permit for any permanent exterior sign attached to your building or standing on your property, while temporary signs like banners, yard signs and window graphics are usually allowed without a permit up to a size and time limit set by local code. The rules live in your city or county zoning ordinance, they vary block by block with zoning districts, and the sign shop cannot get the permit for you unless you hire them to, so the safe sequence is: read the local sign code first, design second, print third.
Key takeaways
- Permanent signs, wall signs, monument signs, projecting signs and most illuminated signs generally require a permit before installation.
- Temporary signage, banners, A boards, window graphics and yard signs, is often exempt but nearly always capped by size, quantity and duration.
- Sign codes are content neutral since the Supreme Court decision in Reed v. Town of Gilbert in 2015, meaning cities regulate size, placement and duration rather than what the sign says.
- Landlords and shopping centers add a second layer of rules through lease criteria, often stricter than the city.
- Unpermitted permanent signs risk fines, forced removal and a stalled certificate of occupancy.
Which signs typically need a permit?
| Sign type | Permit usually required? | Common limits |
|---|---|---|
| Channel letters or wall sign on the building | Yes | Square footage tied to storefront width |
| Monument or pylon sign | Yes | Height, setback and area caps |
| Illuminated sign, including exposed neon look | Yes | Brightness and hours in some districts |
| Vinyl banner on the facade | Often no, time limited | Commonly 30 to 90 day windows, size caps |
| Window graphics | Usually no | Percent of glass coverage, often 25 to 50 percent |
| Yard and site signs | Usually no | Size, count and right of way rules |
Treat this table as the pattern, not your law. The actual numbers come from your municipal code, usually searchable online under sign regulations or the zoning chapter.
How does the permit process work?
- Find your zoning district on the city map, then read the sign section for that district.
- Check landlord sign criteria in your lease. Centers often dictate letter style, color and mounting.
- Prepare a simple site plan and sign drawing with dimensions, materials and mounting method. For illuminated signs, electrical details.
- Submit to the building or planning department with the fee, commonly tens to a few hundred dollars for small business signs.
- Install after approval, and schedule any required inspection.
What can you put up without a permit while you wait?
Most storefronts bridge the gap with temporary and interior signage that codes treat lightly: a printed vinyl banner announcing coming soon within the temporary display window, window vinyl and perforated window film inside the glass coverage limits, interior acrylic lobby signs which need no permit at all, and LED neon hung inside the window, though some cities count interior illuminated signs facing the street, so check that clause specifically.

Why did sign codes change after Reed v. Town of Gilbert?
In Reed v. Town of Gilbert, the US Supreme Court held that regulating signs differently based on their message is content based and presumptively unconstitutional. Since 2015 cities have rewritten codes to regulate only physical characteristics, size, height, location, lighting, duration. For a small business this cuts both ways: the city cannot privilege or punish your message, but neutral limits on size and duration are enforceable and enforced.
Five expensive mistakes to avoid
- Ordering the permanent sign before reading the code, then discovering the allowed area is half your design.
- Ignoring landlord criteria and having to reprint in a mandated color.
- Leaving a temporary banner up past the allowed window and collecting citations.
- Placing yard signs in the public right of way, where crews remove them. Related rules in our yard sign rules guide.
- Skipping the electrical inspection on an illuminated sign, which surfaces at lease end or sale.

Frequently asked questions
Do I need a permit for a temporary banner?
Usually not, but most cities cap banner size and limit display to a window such as 30 to 90 days per year. Check the temporary sign section of your local code.
Who is responsible for getting a sign permit?
The business or property owner by default. Sign companies can file as your agent if arranged, but printing a sign never includes permitting unless stated.
Can my city regulate what my sign says?
Generally no. After Reed v. Town of Gilbert, sign codes must be content neutral, regulating size, placement, lighting and duration instead of message.
What happens if I install a sign without a permit?
Typical outcomes are fines, orders to remove or retrofit, and trouble at inspection time. Retroactive permits often cost more than filing first.
