Home Business in Mount Vernon, NY

If you live in Mount Vernon or are thinking about moving there, home business are one of those things you probably won't think about until they affect you directly. Mount Vernon has 3 specific rules on the books covering different aspects of home business, and some of them might surprise you.

Zoning & Home Occupation Permits

Mount Vernon allows one home occupation or a professional's home office inside a residence, but City Code § 267-18.A limits it tightly: no sign for a customary home occupation, floor space capped at 500 square feet or 25% of one story, whichever is smaller, and only one client served at a time, enforced by the Building Department.

Key details: Governing section: City of Mount Vernon Code § 267-18.A. Floor area cap: 25% of one story or 500 sq ft, whichever less. Signage: No sign for a customary home occupation. Nonresident help: One employee, needs site plan approval or registration. Clientele limit: One visitor served at a time.

A home business that blows past the 500-square-foot/25%-of-floor cap, hangs a sign it isn't entitled to, brings on a second outside worker without site plan approval or registration, or serves more than one visitor at a time stops being a lawful 'customary home occupation' under § 267-18.A. The Building Department can cite it as an illegal use and deny or revoke the certificate of occupancy; citywide, Code § 1-4 sets the penalty for uncured Code violations at up to a $250 fine, 15 days in jail, or both, and up to $500 for a corporation.

Customer Traffic Restrictions

A licensed home occupation or professional office in a Mount Vernon dwelling may serve only one patient, client, customer or other visitor at any one time. Section 267-18.A(6) caps in-person traffic at a single visitor at all times.

Key details: Visitor limit: One patient/client/customer at a time. Governing section: City of Mount Vernon Code § 267-18.A(6). Employee limit: One nonresident partner, associate or employee. Space limit: 25% of one floor or 500 sq ft.

Serving more than one client, patient or customer at a time under the home-occupation exception violates § 267-18.A(6) and removes the use from the protections of that section, exposing it to enforcement as an unpermitted use under Chapter 267's general penalty provision, § 267-56: a fine up to $1,000, imprisonment up to 15 days, or both, per conviction, with each day of continued violation a separate offense.

Signage Rules

Mount Vernon allows a customary home occupation in a dwelling unit but bans it from having any sign at all. Only the narrower category of a professional person's home office may post one sign meeting the standards of the Sign Ordinance, under § 267-18.A(2).

Key details: Home occupation signs: None permitted (§ 267-18.A(2)). Professional office signs: One sign meeting Sign Ordinance standards. Governing section: City of Mount Vernon Code § 267-18.A(2). Related limit: Max 25% of one floor or 500 sq ft.

Posting a sign for a customary home occupation, or a professional-office sign that does not meet the Sign Ordinance standard, violates § 267-18.A(2) and is enforced as a Chapter 267 offense under § 267-56: a fine up to $1,000, imprisonment up to 15 days, or both, per conviction, with each day the sign remains a separate violation.

This is not one of those rules that cities tend to ignore. Mount Vernon actively enforces its signage rules requirements.
