Violations & Fines
Building without the required site development permit, or constructing within the minimum setback without an approved encroachment, exposes the property to a code enforcement stop-work order and permit denial until the structure is brought into conformance or removed. Because setbacks are baked into the site development permit findings under Chapter 18.10 SCCC, a violation typically blocks final inspection and certificate of occupancy rather than triggering a standalone fine schedule.
