Riverside, California
Additions are where setback and height violations happen most often. Your existing house was built compliant — but adding square footage changes the math on lot coverage, FAR, and setbacks. What was legal before may not be legal after the addition. A second-story addition, for example, can trigger increased side setback requirements in many California cities.
