Building on your lot in Sierra Madre
Sierra Madre sets its own limits on fences, accessory structures and home businesses. A home business that meets all standards gets ministerial review; others may qualify for discretionary review.
Key points
- Fence height: R-1, R-2 and R-3 zones: fences at most 42 inches in the required front yard, 6 feet on interior side or rear lines.
- Accessory structures: Single-story detached accessory structures of 600 sq ft or less are limited to 15 feet; larger or 2-story ones follow main-building standards.
- Home businesses: Under ministerial review, a home business may use 25% of the home's floor area or 400 sq ft, whichever is greater.
