Rockville, MD Home Business: Zoning Restrictions (2026)

Under Rockville's Chapter 25 Zoning Ordinance, a home-based business enterprise is defined as any occupation that provides a service or product and is conducted within a dwelling unit or accessory structure by a resident of the dwelling unit without diminishing its residential character. The ordinance specifically excludes certain activities from the home-based business classification: bed-and-breakfast establishments, boardinghouses, day care facilities, display of goods not associated with a home-based business enterprise, landscape contractors, private educational institutions, tourist homes, and motor vehicle repair and maintenance. These excluded uses have their own zoning classifications and may require separate approvals. Home-based businesses must comply with general residential zoning standards including limits on noise, traffic, signage, and storage of materials. The business may not alter the exterior appearance of the residence or generate traffic, parking, or noise inconsistent with the residential neighborhood. Montgomery County also requires registration for home occupations classified as low-impact or major, and Rockville residents must comply with both city and county requirements.
