YOUR CENTRAL ORANGE COUNTY SUNROOM CONTRACTOR

One Contractor for Old Town, Tustin Ranch and Everything Between

Adding a room in Tustin is rarely the same job twice. Around Main Street and El Camino Real, homes sit inside the city's Cultural Resources District, where exterior changes can call for a Certificate of Appropriateness alongside the building permit. A few miles north, Tustin Ranch homes answer to homeowners associations with their own architectural guidelines. Knowing which rulebook applies is half the work.

We take that off your plate. A sales designer visits for a free in-home quote, we run a site check, then prepare the engineering, HOA submittal and City of Tustin permit package ourselves. Installation is handled by factory-trained crews, and our Buena Park showroom is about 20 to 25 minutes away if you want to walk through full-size rooms first. For service-by-service detail, see our neighboring Orange sunroom contractor pages.

WHY HOMEOWNERS HIRE US IN TUSTIN

We Know How Tustin Builds

Historic blocks, HOA communities and new construction each come with their own approvals. We handle all three.

01

Old Town Sensitivity

For homes in the Cultural Resources District, we design additions that respect the original house and prepare the documentation design review expects.

HOA Paperwork, Done

Tustin Ranch and other master-planned neighborhoods have architectural committees. We assemble drawings, specs and color samples for your HOA application.

03

Newer-Home Know-How

Homes at Tustin Legacy and other recent communities often come with compact yards and builder patio slabs. We plan rooms that make the most of that footprint.

04

California-Made, Close By

C-Thru is built in Riverside, Duralum in Sacramento, and Four Seasons manufactures in California. See them in person at our Buena Park showroom.
