Luxury Remodeling in Tustin
In Old Town, a pool or addition that needs a permit also needs historic approval.
Building Here
Historic Old Town, Planned Tustin Ranch
There are effectively two building environments here. Old Town sits in the Cultural Resources District, where improvements that need a building permit also need a Certificate of Appropriateness. Its historic stock runs from Victorian-era houses through Arts and Crafts, Period Revival and mid-century homes, many with raised foundations and undersized services.
The Ranch and Legacy tracts are the opposite: newer construction, engineered pads, and an association design committee that reviews color, roof and fence details before the city ever sees plans.
The historic core has generous, deep lots with detached garages and alley access behind period homes. Ranch and Legacy tracts are engineered pads with tighter, walled rear yards and association oversight.
The team that plans your Tustin project is the team that builds it.

The Ground Rules in Tustin
Permits in Tustin
City of Tustin Community Development Department, Building Division
The Community Development Department covers Planning, Building, Code Enforcement, Historic Preservation, Housing and Economic Development; the Building Division provides plan review, permit issuance and inspections, and plans are submitted electronically with an inspection request line for scheduling.
Permits are valid for 180 days unless work is active and progressing, in which case validity continues until completion. The city offers plan check by appointment for minor projects including patio covers, fences, block walls, pools and spas, and residential kitchen and bath remodels.
Properties inside the Cultural Resources District (which was surveyed in the city's 2021 Historic Resources Survey) require historic review and a Certificate of Appropriateness for exterior changes, and staff apply published style guides when assessing compatibility.
Permit details checked September 2026 against City of Tustin. Rules change, so we confirm them again for your parcel.
What We Plan For
- Certificate of Appropriateness packages
- Historic-compatible exterior detailing
- Panel and service upgrade planning
Pre-war and early postwar homes in the historic core sit on raised foundations with crawl spaces, undersized electrical services and original galvanized supply lines that surface as soon as a real scope opens up.
Deep, mature street trees and long-established rear-yard canopy mean root systems frequently conflict with pool shells, footings and trenching routes.
Newer master-planned tracts sit on engineered pads with expansive clay below, requiring moisture-conditioned subgrade and deepened footings for structures and heavy hardscape.
Alley-served and zero-lot-line configurations in parts of the newer product limit staging and often require crane or conveyor access for backyard work.
