Violations & Fines
A home occupation that spills outside the house, runs with more than one outside worker, or operates loud equipment or deliveries outside the 7:00 a.m. to 10:00 p.m. window is a zoning violation the Department of Planning and Development can cite through the Zoning Enforcement Officer; because home occupations must be disclosed in any conditional use permit, the county can also attach or revoke conditions limiting an operation found out of compliance.
