Full Breakdown

LDC § 12-2-404(B)(2) lists physical-feature restrictions that apply to every home-based business permitted under Table 12-2-302. Subsection (a) prohibits the posting or installation of signs to advertise the business outright: there's no size or number allowance the way there is for other temporary signage in the LDC. The same subsection bars exterior modifications, new dedicated entrances, and outdoor storage or displays that would alter the residential character of the lot, so the sign ban is part of a broader rule keeping home businesses invisible from the street.

Violations & Fines

Posting any advertising sign for a home-based business violates § 12-2-404(B)(2)(a) and can jeopardize the business's required City license.
