Home occupations in The Bronx are governed by NYC Zoning Resolution Section 12-10 and allowed in residential districts only if they meet strict conditions: incidental to the residence, no more than 25 percent of unit floor area (max 500 sq ft), no non-resident employees, and no external evidence of business.
Zoning Resolution 12-10 defines home occupation narrowly. Allowed uses include professional offices (lawyer, architect, accountant), dressmaking, teaching up to 4 pupils, and artist studios. Prohibited in the home include advertising signs, stock-in-trade retail, restaurants, animal hospitals, and medical offices open to the public. DOB requires the unit to retain its residential C of O. Certain professions (doctors, dentists) are allowed under Use Group 6B in some districts with additional conditions. DCWP business license may still apply depending on activity.
DOB illegal-use violations start at $800. Exceeding 500 sq ft or having employees converts the home to commercial use without proper C of O and can trigger $10,000+ fines.
