Tustin, CA Fence Regulations: Fence Requirements (2026)

Under the City of Tustin's user guide, a fence or wall over three feet requires approved plans and a permit issued by the Building Division, and a City Building Inspector must inspect and final the construction. Submittals require two copies of a plot plan showing the owner, address and APN, lot dimensions and boundary lines, and the dimensioned location and yard setbacks of the proposed fence/wall with notes on height, color and materials, plus foundation/wall design specifications as required by the Building Official (footing details, reinforcement, engineering calculations). It is the permit applicant's duty to keep the work accessible and exposed for inspection. Required inspections are: (1) when footing excavation is complete and reinforcing is in place but before concrete is poured; (2) for masonry walls, a pre-grout inspection after the block is laid and reinforcing is in place but before grout is poured (block may be laid up to 6 feet before calling for pre-grout); and (3) a final inspection when work is complete. A separate City requirement applies to pools: swimming pools, spas and hot tubs must be enclosed by a barrier. California's Swimming Pool Safety Act sets a minimum barrier (commonly a 60-inch / 5-foot enclosure) with self-closing, self-latching gates and limited gaps; pool owners should confirm the current enclosure standard with the City Building Division and the adopted California Building Code. Within the Cultural Resources District, additional design review may apply to fences and walls.
