Gaithersburg's Home Business: The Rules That Matter

Every city handles home business a little differently. In Gaithersburg, Maryland, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Home Daycare

Gaithersburg zones small family day care as a by-right accessory use in every residential district, permitted by right in single-family, duplex, townhouse and stacked dwellings under Table 24-3.1-1. Large family day care needs a special exception from the board of appeals in every residential zone. Both classifications must follow the home-based-business signage standards under section 24-5.4.

Key details: Small family day care: By-right accessory use in most zones. Large family day care: Special exception required, all zones. Live/work dwellings: Both classifications prohibited. Signage: Must follow home-based-business sign rules. Approving body: Board of appeals for special exceptions.

Operating a large family day care without board of appeals approval, or exceeding the sign standards incorporated by section 24-5.4, is a zoning violation enforced as a municipal infraction under section 24-15.1 and chapter 1, section 1-9. The city manager or designee can order the use discontinued, and Planning and Code Administration investigates complaints. Fines run up to the council-set maximum, with an added penalty of up to $1,000 for late payment, and section 1-11 permits a lien against the property for correction costs.

Zoning & Home Occupation Permits

Gaithersburg permits home-based businesses under section 24-5.5 as either a no impact, minor impact, or material impact use, with permit requirements scaling from simple registration to a board of appeals special exception. Every home business is capped at one-third of the property's total floor area, needs a city license before opening, and cannot be a cannabis business or a short-term rental.

Key details: Classifications: No impact, minor impact, material impact. Floor area cap: 1/3 of all structures on the lot. License required: Before business may commence operation. Barred businesses: Cannabis businesses and short-term rentals. Registration term: 3 years, renewed triennially.

Operating a home-based business without the required registration or special exception, exceeding the one-third floor-area cap, or running a business the code categorically bars, such as a cannabis business or short-term rental, from a home is a zoning violation under section 24-15.1, enforced as a municipal infraction under chapter 1, section 1-9. The city manager can suspend or revoke approval, fines run to the council-set maximum with up to $1,000 added for nonpayment, and section 1-11 allows a lien against the property for correction costs.

Customer Traffic Restrictions

A Gaithersburg home business classified as minor impact may host no more than 20 client, customer or business-associate visits per week, counted per stopping vehicle, and no more than one non-resident employee. Exceeding either limit pushes the business into the material impact category, which requires a special exception from the board of appeals instead of simple city registration.

Key details: Weekly visit cap: 20 visits for minor impact tier. Visit definition: One vehicle per stop with clients/customers. Non-resident employees: One permitted in minor impact tier. Registration term: 3 years, renewed triennially. Over the cap: Reclassified as material impact, special exception.

Running a minor impact home business over the 20-visit weekly cap, or with more than one non-resident employee, without seeking material impact special exception approval is a zoning violation under section 24-15.1, enforced as a municipal infraction under chapter 1, section 1-9. The city manager can suspend or revoke the registration for noncompliance, and continued violation can be referred as a citation carrying an added fine of up to $1,000 for late payment, with section 1-11 allowing a lien for correction costs.

Signage Rules

A Gaithersburg home-based business may display exactly one non-illuminated, permanent building sign, capped at 9 inches by 12 inches and 0.75 square feet, and it cannot protrude more than 2 inches from the wall. Section 24-5.5(E) requires the sign to face a public street or entrance and be installed under the city's sign permit process.

Key details: Signs allowed: One non-illuminated permanent building sign. Maximum size: 9 in. by 12 in., 0.75 sq ft. Maximum protrusion: 2 inches from the building. Placement: Facade facing a public street or entrance. Permit required: Sign permit under § 24-8.6.

Installing a sign larger than 0.75 square feet, an illuminated sign, a freestanding sign, or any sign without a permit under section 24-8.6 for a home-based business violates section 24-5.5(E) and is enforced as a municipal infraction under section 24-15.1(C) and chapter 1, section 1-9. The city manager or designee can order a noncompliant sign removed, and if the owner does not comply, the city may remove it and bill the owner for removal costs.

The Bottom Line

Gaithersburg's home business 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.
