Full Breakdown

Violations & Fines
A structure built into a required front, side or rear yard setback is a zoning violation subject to the enforcement provisions of Title 17; the community development department can withhold or revoke a building permit and require removal or relocation of an encroaching structure. Building without first obtaining an approved permit that reflects the correct district setbacks compounds the violation and can trigger a stop-work order until a variance under Chapter 17.62 is approved or the structure is brought into conformance.
