Full Breakdown
Rockville's Zoning Ordinance splits home occupations into two tiers. 'Little to No Impact' businesses -- one non-resident employee, up to four customer visits daily -- are permitted outright. 'Material Impact' businesses, with two or more employees or five to eight visits a day, need a Special Exception from the City's Board of Appeals under Article 4, Division 4.3, disclosing parking, hours, staffing, and licensing, and are subject to inspection by the Chief of Zoning. Either tier is capped at 35% of the dwelling's gross floor area or 400 square feet, must stay accessory to the residence, and the operator must live on-site at least 220 days a year.
Violations & Fines
Operating a Material Impact home business without the required Special Exception, or exceeding the floor-area, employee, or visitor caps, is a zoning violation enforceable by the City's Zoning Administrator under Article 13.
