How Gaithersburg Handles Sign Regulations: A Practical Guide
Gaithersburg maintains 95 local ordinances across all categories, and 3 of those deal specifically with sign regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Gaithersburg falls on the strict-to-permissive spectrum compared to other cities.
Window Signs
Gaithersburg caps permanent window signs at 25 percent of a window's surface under City Code § 24-8.29, with temporary window signs subject to the same 25 percent limit under § 24-8.30, except that a vacant non-residential storefront may cover up to 95 percent of its window space for up to nine months a year. Window signs are exempt from a permit but still count toward regulatory limits.
Key details: Permanent window sign cap: 25% of window surface, § 24-8.29. Temporary window sign cap: 25% of window surface, § 24-8.30. Vacant storefront exception: Up to 95% for up to 9 months. Frame clearance: 4 inches minimum from window frame. Temporary display limit: 3 months per calendar year.
Because window signs still count toward article 8's regulatory limits even without a permit, exceeding the twenty-five percent coverage cap or the display-time limits is enforceable under § 24-15.1(C): the city manager or a designee may order a noncompliant window sign removed, and if the owner does not comply, the city can remove it and bill the cost to the owner. Removal or denial decisions may be appealed to the board of appeals under § 24-12.9, Administrative review.
Digital Billboards
Gaithersburg bans billboard signs outright under City Code § 24-8.3(E). Electronic message display signs are allowed only as part of a building, monument or geographic-area sign, are banned on single-family lots and in the RB zone, and are capped at one per 10 to 15 acres depending on zone, with brightness limited to 5,000 nits by day and 500 nits between dusk and dawn.
Key details: Billboards: Prohibited outright, § 24-8.3(E). RB zone / single-family lots: Electronic displays not permitted at all. Non-residential/floating zone count: 1 per 10 acres (1 per 15 in CB). Brightness, daytime: 5,000 nits maximum. Brightness, dusk to dawn: 500 nits maximum.
Sign violations fall under § 24-15.1(C): the city manager or a designee enforces Article 8, can inspect property at reasonable times, and may order the removal of any sign that does not conform, including an unpermitted or oversized electronic display or an outright-banned billboard. If an owner fails to comply with a removal order, the city may remove the sign itself and bill the permittee or owner for the cost. Owners can appeal a removal, denial, revocation or suspension order to the board of appeals under § 24-12.9.
This is one of the stricter rules in Gaithersburg's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
Holiday Displays
Gaithersburg exempts holiday and seasonal signs from permits under City Code § 24-8.4(A)(7): a temporary sign of 20 square feet or less and 8 feet or shorter, with no foundation, can go up within 20 days of a recognized holiday or seasonal event and may be illuminated. Larger seasonal signs on multifamily or nonresidential property lose the regulatory exemption and need a permit.
Key details: Exempt size: 20 sq ft or smaller, 8 ft or shorter. Display window: Within 20 days of the holiday/event. Illumination: Permitted for exempt seasonal signs. Multifamily oversize threshold: Over 12 sq ft or 6 ft tall. Non-residential oversize threshold: Over 20 sq ft or 8 ft tall.
Because seasonal signs above the exempt thresholds still need a permit, installing one without applying under § 24-8.6 is enforceable the same as any other unpermitted sign: the city manager or a designee can inspect the property, order the sign removed under § 24-15.1(C), and remove it directly and bill the owner if the order is not followed. A denial or removal order can be appealed to the board of appeals under § 24-12.9, Administrative review.
If you are coming from a city with tighter rules, you will find Gaithersburg gives residents more flexibility on holiday displays.
The Bottom Line
Gaithersburg's sign regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Gaithersburg is broadly strict or permissive.
