San Bernardino County Height Limits Rules (2026) — What You Need to Know

San Bernardino County's fence and wall regulations are codified in Chapter 83.06 of the Development Code, which covers fences, hedges, and walls in unincorporated areas. The heights allowed in required setback areas are set out in Table 83-6, referenced by Section 83.06.030 (General Height Limitations).

For standard residential zones (RS — Single Residential), the maximum fence height in the front yard is 4 feet. Side and rear yard fences may be up to 6 feet tall. Properties zoned RC (Resource Conservation) or RL (Rural Living) receive an exception allowing front yard fences up to 5 feet, reflecting the more rural character of these zones.

Fence height is measured from the finished grade at the location where the fence will be installed, per Section 83.06.040. When there is a difference in ground level between two adjacent parcels, the height is determined using the finished grade of the lower parcel. This prevents property owners on higher ground from effectively building oversized fences relative to their neighbors.

Fences and walls built within the height limitations of Chapter 83.06 are explicitly exempt from the minimum setback requirements of the Development Code, meaning they can be placed right up to the property line. A Walls and Fences Permit is required for construction of masonry walls, retaining walls, and chain link or iron fencing. Plans and supporting documentation must be submitted for review and approval before construction begins, verifying compliance with both the California Building Codes and the San Bernardino County Development Code.
