Tustin homes from Old Town to Tustin Legacy
Tustin runs from the older streets around Old Town, where Main Street and El Camino Real still have buildings from the 1880s, to Tustin Legacy, the newer district where homes sit alongside shops, parks and schools and part of it crosses into Irvine. Most calls we get here come from homeowners who want to close in a back patio or add a room they can use more of the year, the same calls we take in Santa Ana and Garden Grove.
The age of the house usually decides where the hard part of the job is. Older homes near Old Town often have lower rooflines and add-ons from past owners, so tying a new roof in cleanly takes the most planning, while on newer houses the question is more often how much yard there is and where the room fits.

Our services in Tustin, CA
- Patio-to-sunroom conversion
Plenty of Tustin backyards already have a concrete patio right off the back door, and it's usually the first place homeowners picture a room. We keep the slab where it's sound, add proper footings where it isn't, and build the walls, glass and roof so the room ties into the house.
- Three season sunrooms
If you mostly want the patio to be usable more often, our three season sunrooms close it in with glass or screen panels under a solid roof, with no heating and cooling to add. That keeps the build simpler than a fully conditioned room, which suits a lot of the patio calls we get here.
- Four season sunrooms
When the room is meant to be part of the house all year, a four season sunroom gets insulated walls, roof and glass, plus a plan for heating and cooling. We settle that heating and cooling choice first, because it changes the walls, the wiring and the base, and it's much harder to add once the room is up.
- Deck-to-sunroom conversion
Some Tustin houses have a raised wood deck instead of a slab, and a deck built for chairs isn't always built for walls and a roof. We'll tell you whether the framing can be strengthened to hold a room or whether starting fresh makes more sense.
- Patio cover installation
If shade over the back patio is all you're after, a solid or lattice patio cover gets you there with far less work than a closed room. We set the posts and attach the cover to the house, and we can plan it so walls could be added later if you change your mind.
- Sunroom remodeling
Older sunrooms and closed-in patios around Tustin often have leaky seams, single-pane glass or a roof that was never tied in well. We find where the trouble starts, then repair or replace the glass, roof panels and trim so the room is comfortable to use again.
What Tustin houses ask of a new sunroom
Every sunroom we build in Tustin comes down to what it sits on and how it meets the house. A patio slab poured for a table and a grill wasn't always poured to carry walls and a roof, and a deck can look fine on top while the posts underneath say otherwise, so we look at the base before anything else. The price moves with the room's size, the glass and roof you pick, whether it gets heating and cooling, and how much work the base needs, and the schedule mostly turns on that base work and the city's plan review. Your own figure comes from the estimate, once I've seen the house.
A sunroom is a room addition, and in Tustin the city's Building Division issues the permits for room additions, reviews the plans and inspects the work. We're licensed and fully insured, and when your room needs a permit, we prepare the plans, file them with the city and meet the inspector, and we keep you posted along the way.

Sunrooms and patio rooms
Tustin sunroom questions answered
Do I need a permit for a patio cover or deck in Tustin?
Yes, in most cases, because the city's permit FAQ says solid cover patios, lattice patios and decks need a building permit. An older city guide exempts open concrete slabs and wood decks no more than 30 inches above the ground that aren't over a story below, so the two don't agree on low decks. We check the current rule with the Building Division before we plan, rather than guess.
Do I need a permit to add outlets or air conditioning to a sunroom in Tustin?
Yes, the city requires a permit for any new or changed electrical, plumbing or mechanical system, which covers new outlets, lights and a heating and cooling unit. The older city guide lets you swap an existing light fixture or outlet without one, but wiring a new room is new work. That's one reason we settle heating and cooling at the start, so it's on the plans from the first submittal.
How do I know if my sunroom project needs a grading permit in Tustin?
You need a grading permit in Tustin if the job moves more than 50 cubic yards of earth, uses a foot of fill, or cuts a slope taller than 5 feet. A room on an existing flat patio usually stays well under that, but a new pad on a sloped yard can cross it. The application goes to the Building Division with grading plans and preliminary soil reports, so we flag it at the first visit if your lot might need one.
How long does a building permit last in Tustin?
A Tustin building permit is good for 180 days, and it stays valid until the project is done as long as the work is active and moving. The city wants plans submitted before any building or grading starts and checks them against its zoning, grading and building rules. We file once the plan is settled and schedule the build so the work keeps moving once it starts.
How do I pay Tustin permit fees safely?
Pay Tustin permit fees only through the city's Citizen Self Service portal or in person at the Finance counter at City Hall, as its permits process page explains. The city says fraud tied to permit fees is on the rise and that it doesn't ask for a bank routing or wire number. If anyone asks you for one, don't send it.
How much does a sunroom cost in Tustin?
A Tustin sunroom costs what its size, glass, roof, heating and cooling and base work add up to, so the only honest number for yours comes after I've measured and looked at what it sits on. Local costs can come into it too, like the plans and permit for a room addition, and on a sloped lot a grading permit with its plans and soil reports. Call (657) 205-6766 or send us the form and I'll come out to look.
