681, are excluded from that 50 percent cap.

Violations & Fines
Paving a driveway or parking area with an unapproved surface, or letting paved parking, aisles and driveways cover more than half of a residential lot's required front yard setback, violates SCCC § 13.16.060(H). Changing the approved number of parking spaces without first obtaining a minor site development permit or permit amendment under Chapter 18.10 SCCC is also a violation; property owners may instead apply to the Zoning Administrator for a minor exception under the same chapter.
