Summary

In the City of Tustin, Sec. 8101 amends the 2025 California Building Code's administrative rules on when a permit is required: grading, moving a building, and demolishing a building or structure, including an in-ground swimming pool, all need a Building Official permit before work starts, with fees set by City Council resolution.

105.1.3 Grading Permits. The Building Official may issue permits for grading and for construction, demolition, addition, alteration, and installation of improvements. Improvements subject to permit requirements include but are not limited to: streets, parking lots, curb and gutter, driveways, sidewalks, disabled access ramps and signage, ... storm drains, junction structures, catch basins, sewer mains and laterals, water mains and services, landscaping irrigation, and miscellaneous on-site improvements. In addition, all improvements shall comply with the Grading Ordinance and the Water Quality Ordinance of the Tustin City Code. ... 105.1. ... 4 Relocation of Buildings. No building or structure shall be moved or relocated unless and until the necessary permits to relocate the building or structure have been issued by the Building Official. ... 105.1.5 Demolition of Building or Structure, including in-ground swimming pool. No building or structure, including in-ground swimming pool, shall be demolished unless and until the necessary permits to demolish the building or structure have been issued by the Building Official.

Full Breakdown

Sec. 8101(e) adds three permit provisions to the City's adopted Building Code. Under 105.1.3, the Building Official may issue permits for grading and for construction, demolition, addition, alteration and installation of improvements, and the section lists what counts: streets, parking lots, curbs and gutters, driveways, sidewalks, disabled access ramps and signage, storm drains, junction structures, catch basins, sewer mains and laterals, water mains and services, landscaping irrigation, and other on-site improvements, all of which must also comply with the City's Grading Ordinance and Water Quality Ordinance.

Section 105.1.4 requires a permit before any building or structure is moved or relocated, with the Building Official determining which year's codes apply to the relocated structure. Section 105.1.5 requires a permit before any building or structure, including an in-ground swimming pool, is demolished, and the Building Official can collect a refundable cash deposit or surety bond, set at $5,000 plus $2 per square foot over 1,000 square feet, to cover cleanup or repair if the permittee defaults. Beyond these additions, Sec. 8101(b) broadens the underlying Building Code's scope to reach every property in the City except work primarily in a public right-of-way, public utility towers and poles, unregulated mechanical equipment, hydraulic flood control structures and local-agency water or electrical facilities.

Sec. 8101(g) and (h) cap a permit application at 12 months before it expires unused, and cap an issued permit at 12 months to start work or 180 days of suspension before it lapses, with up to two 180-day extensions available on written request.

Violations & Fines

Building without the required permit exposes an owner to the City's building-and-safety-code penalty track under Sec. 1121: a first infraction fined up to $100, a second up to $500, and a third or later violation within a year up to $1,000, or prosecution as a misdemeanor carrying up to $1,000 and six months in the Orange County jail. Sec. 8101(e) also lets the Building Official charge an investigation fee, on top of the permit fee, for any work started without a permit before one can be issued.
