You’ve designed the perfect storefront sign. But before you call the installer, there’s one step too many business owners skip: sign permits and regulations.
Most cities require permits for commercial signage. Skipping this step can cost thousands in fines and forced removal. This guide covers everything you need to know about business sign permits, sign regulations, and sign code compliance.
Do You Need a Permit for a Storefront Sign?
In almost every case, yes. Most municipalities require a storefront sign permit for any new sign installation, replacement, or substantial modification.
Some exceptions exist for very small signs (under 6 square feet) or temporary sandwich boards, but these vary by location. Permanent illuminated signs, projecting signs, and signs over size thresholds almost always require a permit. Working with a professional sign design company helps navigate these requirements efficiently.
Types of Sign Permits
- Building Permit — Required for signs attached to a structure, especially those involving structural modifications or mounting hardware that penetrates the building envelope.
- Electrical Permit — Required for illuminated signs, channel letters, and LED displays connected to the building’s electrical system. An electrical inspection verifies proper wiring.
- Sign Permit — The specific permit for the sign itself. This involves submitting design drawings, dimensions, materials, and proposed location for city review.
- Historic District Review — Required in historic preservation areas. These districts enforce stricter rules on materials, colors, illumination, and mounting styles.
Permit costs range from $50 for a basic sign permit to over $500 for larger illuminated signs in major cities.
Common Sign Regulations by City Type
While every city has its own code, most sign regulations center on a few key parameters:
- Size Limits — Typically 1 to 2 square feet per linear foot of storefront frontage, with absolute maximums of 100-200 square feet.
- Height Limits — Maximum mounting height for wall signs and maximum height for freestanding signs like monument or pylon signs.
- Illumination Restrictions — Rules on internal vs. external illumination, brightness levels, and whether neon, LED, or backlit signs are permitted.
- Projection Limits — How far a sign can extend from the building face. Typical limits: 12-18 inches for wall signs, up to 4 feet for projecting signs with 8-10 feet of clearance.
- Movement and Animation — Many cities restrict animated or flashing signs, especially near residential zones.
Zoning Codes & Sign Restrictions
Your property’s zoning classification directly affects allowable signage:
- Commercial Zones — Most permissive. Larger size allowances, more illumination options. But even commercial zones have limits.
- Historic Districts — Most restrictive. Expect limits on materials (no plastic, prefer wood or metal), external lighting only, and strict color and lettering guidelines.
- Mixed-Use and Residential Zones — Tighter size limits, strict illumination rules, and caps on the number of signs per business.
Knowing your zoning designation is the first step in understanding your local sign code compliance requirements.
What Happens If You Don’t Get a Permit?
Skipping permits carries real risks:
- Fines — Daily fines of $100 to $1,000 for unpermitted signs until compliance or removal.
- Forced Removal — The city can order removal at your expense, typically costing $500-2,000 for a standard wall sign.
- Lease Violations — Many commercial leases require compliance with local codes. An unpermitted sign can put your lease at risk.
- Legal Liability — If an unpermitted sign fails and causes injury, insurance may not cover the claim.
The cost of a permit is small compared to these potential consequences.
How to Check Your Local Sign Regulations
- Visit your city’s planning department website. Most cities publish their sign code online. Search for “sign ordinance [your city name]”.
- Check the zoning map. Identify your property’s zoning classification to determine which regulations apply.
- Review the sign code. Look for allowable sign types, size limits, illumination rules, and fee schedules.
- Contact the permitting office. A phone call can clarify ambiguous rules quickly.
- Consult a professional sign company. Experienced sign contractors handle commercial sign permitting daily and know local codes intimately.
How Professional Sign Companies Handle Permitting
One of the best reasons to work with a professional sign company is that most handle the entire permitting process for you:
- Site survey — Assessing your location, measuring available space, and identifying code constraints.
- Permit-ready drawings — Preparing engineered drawings with dimensions, mounting details, materials, and structural calculations.
- Application submission — Submitting the complete package to the permitting office, including site plans, elevations, and sign details.
- Permit tracking and follow-up — Handling revisions and communications with the city.
- Inspections — Scheduling and coordinating electrical and final sign inspections after installation.
Frequently Asked Questions
How long does it take to get a sign permit?
Typical processing ranges from 1 to 4 weeks. Simple wall signs in small towns may take days, while large illuminated signs in major cities can take 6-8 weeks.
Can I install my own sign without a contractor?
Yes, property owners can apply for permits themselves. However, you still need the same design drawings and specifications, and the sign must meet all codes.
Do digital signs have different permit requirements?
Yes. Electronic message centers face additional restrictions on brightness, message dwell time, and animation. Some cities prohibit them entirely in certain zones.
Do I need a permit to change sign copy?
Minor copy changes like updating a phone number typically don’t need a permit. Replacing the entire sign face or changing dimensions likely does.
What information do I need to apply?
Most applications require: property address and zoning, detailed sign drawings with dimensions, location on the building, materials specifications, electrical details (if illuminated), structural calculations, and landlord authorization for leased spaces.
