Petaluma FAQ
Do I need a permit for a standard 6-foot backyard fence?
No. Under the post-2025 standards, a fence up to 6 feet in a side or rear yard does not require a county permit, provided it sits at least 6 inches outside any right-of-way or easement and uses permitted materials.
When do I need a building permit?
A building permit is required when a solid wood, concrete, or masonry fence exceeds 7 feet, or when any fence (regardless of material) exceeds 10 feet. Fences over 8 feet must also be designed by a licensed architect or engineer.
Are use permits still required for tall residential fences?
No. Ordinance No. 6547, adopted Dec. 16, 2025, eliminated the use-permit requirement and replaced it with objective height, material, and design standards reviewed administratively.
What is Administrative Design Review?
ADR is a staff-level review (no public hearing) required for solid fences 3 to 6 feet tall in front or street-side yards and for non-exempt fences in the SR Scenic Resources combining district.
Santa Rosa FAQ
Do I need a permit to build a 6-foot wood fence in my Santa Rosa backyard?
No zoning or building permit is required for a 6-foot fence (or a 6-foot fence with up to 2 feet of lattice) in your interior side or rear yard outside the front/street-side setback. Permits are only required if the fence exceeds 7 feet total or if you wish to exceed the standard Table 3-1 height limits.
What permit do I need for an 8-foot solid fence in Santa Rosa?
An 8-foot solid fence in a residential setback requires both a Minor Director Conditional Use Permit (to exceed Table 3-1 height limits) and a Building Permit (because the fence is over 7 feet). The Conditional Use Permit application is processed by the Planning Division.
Are temporary construction fences exempt from permits?
Yes. Section 20-30.060.F states that 'nothing in this Zoning Code shall be deemed to prohibit the erection of a temporary fence around construction works in compliance with the Building Code and other applicable provisions of the City Code.'
