Full Breakdown

Posting an advertising sign, window display, or other identification of a Home Occupation beyond a house number and nameplate violates §8.64.030.Q and is a violation of the Chapter's Limitations on Use, enforced under §8.64.060 through Chapter 8.144 (Enforcement) and Chapter 4.04 (Business Registration).
