Summary
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).
Office in residence of a professional person and customary home occupations. ... In districts where permitted, one office of a professional person or a customary home occupation may be established in a dwelling unit subject to the following: ... No signs shall be permitted for a customary home occupation. For the office of a professional person, one sign meeting the requirements of Chapter 267, Article XIII, Sign Ordinance, shall be permitted.
Full Breakdown
A of the zoning code, Additional Regulations for Residence Districts, lets a resident run one office of a professional person or a customary home occupation inside a dwelling unit where the district permits it, subject to a tight set of conditions. Subsection A(2) draws a sharp line on signage: no signs shall be permitted for a customary home occupation, while the office of a professional person is allowed exactly one sign, and that sign must meet the requirements of Chapter 267, Article XIII, the Sign Ordinance.
A frames how narrow the home-business allowance is generally: the use must be located entirely inside the practitioner's own dwelling unit, not in any accessory building; the practitioner must actually live there; only one nonresident partner, associate or employee may work on site, and only after site plan approval or, for an existing structure, registration with the Building Department; the space used cannot exceed 25% of one floor's area or 500 square feet, whichever is less; and no more than one client, patient or customer may be present at any time.
A home-based business that is not a licensed professional's office, such as a hairdresser, tutor, or crafts seller working from home, cannot post a yard sign, window sign, or any other sign advertising the business under this section, no matter how small.
Violations & Fines
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.
