Summary
A home-based business in the District can post exactly one sign, and it has to be small, flat, and unlit. 11 DCMR-U § 251.4 caps a home occupation sign at 144 square inches, requires it to be flush-mounted with no illumination, and limits its text to the practitioner's name and occupation type.
(a) No more than one (1) exterior sign may be displayed on a dwelling or other building in which a home occupation is practiced, regardless of the number of home occupations permitted in the dwelling or building; (b) The sign shall not exceed one hundred forty-four square inches (144 sq. in.) in area; (c) The sign shall be flush-mounted; (d) The sign shall not be illuminated; and (e) The sign may state only the name of the practitioner and the type of home occupation.
Full Breakdown
4 governs signage for any dwelling or building where a home occupation is practiced. 1 still gets a single sign, not one per business. Subsection (b) caps that sign at 144 square inches, roughly the size of a standard sheet of paper. Subsection (c) requires the sign to be flush-mounted against the building rather than freestanding or projecting, and subsection (d) bars any illumination, ruling out backlit or neon signage. Subsection (e) also restricts the sign's content: it may state only the practitioner's name and the type of home occupation being conducted, so advertising copy, hours, phone numbers, or pricing cannot appear on it.
2, meaning a sign that meets the size and content rules still doesn't excuse the underlying business from needing a permit. A noncompliant home occupation sign is treated as a zoning violation subject to the same enforcement standards as any other unauthorized sign in a residential zone.
Violations & Fines
A home occupation sign that exceeds 144 square inches, is illuminated, projects from the building, or carries more than the practitioner's name and occupation type violates 11 DCMR-U § 251.4. Under § 305.1, that is punishable by a fine of up to $100 per day the sign remains posted, and under § 305.2 a neighbor specially harmed by the sign can seek a court order to have it removed.
