Summary

Washington County, Maryland lets a home business operate as a zoning-exempt "Home Occupation" only if it does not generate vehicular parking, freight, delivery, or other nonresidential traffic beyond what a normal household would produce. The Zoning Ordinance's Article 28A definition ties this traffic limit to four other conditions a home business must meet at once.

These county ordinances apply to unincorporated areas of Washington County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Home Occupation: Any use of a dwelling or accessory building conducted solely by a member or members of the family residing therein, which is incidental or subordinate to the main use of the building for dwelling purposes and meets all of the following criteria: ... B. The use does not generate vehicular parking, freight and delivery traffic or other nonresidential traffic to a greater extent than would normally result from residential occupancy;

Full Breakdown

Article 28A of the Washington County Zoning Ordinance defines "Home Occupation" as any use of a dwelling or accessory building conducted solely by a member of the resident family, incidental or subordinate to the dwelling's residential use, and meeting five criteria at once. " That comparison point is an ordinary house, not a commercial baseline, so a business that brings in a steady stream of client vehicles, delivery vans, or freight trucks beyond what a family home would generate loses its Home Occupation status. The definition does not set a numeric trip cap or a client-visit count; it is measured against what neighbors would expect from a residence.

3(b) in the "RU" Residential, Urban District. 11, or is barred outright in the district. The same Article 28A definition also requires (criterion A) that the use not exceed 2,500 square feet of floor space, (criterion C) that it generate no outside storage of equipment or supplies, and (criterion E) that no exterior evidence indicate the dwelling is used for anything but residential purposes.

Violations & Fines

A home business that outgrows the residential traffic threshold in criterion B stops qualifying as a Home Occupation and becomes an unpermitted use. The Zoning Administrator, under Section 24.2(d), issues written notice by certified mail ordering discontinuance of the illegal use; a property owner who continues faces a misdemeanor under Section 26.1 with a fine up to $1,000 per day, or a civil citation under Section 26.2.1 capped at $500.

Frequently Asked Questions

Is there a set number of client visits allowed for a home business in Washington County, Maryland?
Criterion B of the Article 28A Home Occupation definition says the use "does not generate vehicular parking, freight and delivery traffic or other nonresidential traffic to a greater extent than would normally result from residential occupancy." There is no fixed number of client visits in the ordinance; the county measures the traffic against what a typical household would generate, not against a set daily count.
What happens if my home business generates too much traffic?
If your business brings in regular delivery trucks, freight vehicles, or a steady flow of client cars beyond what a household normally produces, you no longer meet criterion B of the Home Occupation definition. The Zoning Administrator can order the use discontinued under Section 24.2(d), and continuing to operate can bring a misdemeanor fine of up to $1,000 per day under Section 26.1.
Are there other conditions besides traffic for a home business to qualify?
Yes. The Home Occupation definition in Article 28A requires the traffic limit (criterion B) alongside a 2,500 square foot floor space cap (criterion A), a ban on outside storage of equipment or supplies (criterion C), a signage limit, and a requirement that nothing visible, audible, or odoriferous from outside the dwelling suggest a nonresidential use (criterion E).
