General Contractor in Tustin, CA
A general contractor in Tustin, CA works with the City's own Building Division, a Cultural Resources District in Old Town, a soils policy for additions and an East Tustin hillside with its own roof rule. Several City documents disagree, so each point gets a phone call. MDG Builders, CSLB #1040337, manages all eleven trades here.
Eleven trade guides for a city of groves, tracts and an old air base
Every guide starts from the Tustin handouts and ordinance text we could open, plus Census housing counts. The prices are Los Angeles planning ranges and not Tustin bids, and no permit fee is printed anywhere on these pages.

Tustin began in 1868, when Columbus Tustin, a carriage maker from Northern California, and Nelson Stafford bought 1,300 acres of the old Rancho Santiago de Santa Ana and platted a townsite around 1870. Lots were given away when sales dragged, the Southern Pacific terminus went to Santa Ana in 1877, and apricot and walnut groves slowly gave way to Valencia oranges. The city incorporated on September 21, 1927 with just over 900 residents and counted only 1,143 in 1950. Then the Santa Ana Freeway arrived in 1955, citrus disease pushed growers to sell, and tracts replaced groves; the City reports its population climbing from 2,006 to 22,313 during the 1960s. The Census Bureau's 2024 estimates count 30,118 housing units, with 55.4 percent of occupied homes rented, about 46 percent built before 1980 and the 1960s the largest decade at 23.7 percent. Only about 4 percent predate 1960. That mix means a kitchen remodel or bathroom remodel often opens walls to 1960s wiring and supply lines, house painting and window replacement fall under EPA's lead-safe rule on many homes, and flooring jobs meet slabs that have aged for decades.
Tustin issues its own permits. The Building Division sits under Community Development, takes applications through the Citizen Self Service portal, and offers plan check by appointment of up to one hour for minor jobs such as patio covers, fences, pools and kitchen or bath remodels. Plan reviews submitted on or after January 1, 2026 fall under the 2025 California codes plus local amendments in Ordinance 1569. The City's web page still calls that ordinance proposed, yet the November 18, 2025 council packet shows it passed and adopted that day, so we treat it as adopted and ask you to confirm. The same split runs through other documents. One City page says a permit stays valid for 180 days while work is active, another voids it after 360 days without a start, and the ordinance allows 12 months to begin. Fences and sheds are muddier still: the ordinance exempts fences up to 6 feet and small sheds, while the City's FAQ asks for a permit on every shed and on fences over 3 feet. We state both sides on each trade page and send you to the Building Division at 714-573-3130 before you buy materials. We never read the official code on Municode, so the fence and Cultural Resource District text comes from a labelled Zoneomics mirror, and the City should confirm it. Fire service comes from the Orange County Fire Authority, not a Los Angeles County agency.
Roofs, fences and soil show how Tustin's rules stack. Ordinance 1569 makes Class B the floor for a new roof, or one more than half replaced within a year, outside the state fire zones, while the City's older reroofing guide asks for Class A across the East Tustin Specific Plan Hillside District. That guide predates the 2025 code cycle, so the hillside answer today is a question for Building, and a roof repair or replacement on the hill starts there. Deteriorated roofs, shake, slate, clay or cement tile and roofs with two coverings must be torn off. Fences may reach 6 feet 8 inches, but nothing over 3 feet may stand in the required front setback, which frames most fence work. The City says portions of Tustin sit in the state's fire hazard zones, but we could not read which streets, so check your parcel on CAL FIRE's viewer. Under the soil sits the flat Santa Ana River plain. The City's soils policy waives the report only for additions under 500 square feet outside a liquefaction zone, and for 500 to 1,000 square feet only with a geotechnical engineer's certification, which decides the budget of any room addition. Masonry walls need 24 inch footings in a liquefaction zone, concrete flatwork must drain to the street and never onto a neighbor, and a deck or patio cover meets that document conflict about low decks. The window guide's egress sizes and 0.30 U-factor are the City's 2019 code figures, so we label them that way.
Old Town is the district to check first. The Cultural Resources District, created June 20, 1988, covers the original townsite near First Street, Newport Avenue, I-5 and SR-55, where homes date to the 1870s and 1880s, and exterior work that needs a building permit calls for a Certificate of Appropriateness from Planning at 714-573-3140. We have not read the Old Town design guidelines or the East Tustin Specific Plan, so we cannot say what they allow. The ADU guide carries the other open question: the City's Ordinance 1517 dates to December 2021, the state housing department wrote Tustin on February 27, 2026 that it may be outdated, and whether Ordinance 1578 was adopted is unverified, so state law and a Planning call decide. Unincorporated North Tustin sits just northeast and follows county rules, so confirm that a Tustin mailing address is inside city limits. MDG Builders holds CSLB #1040337 and acts as the general contractor: we scope the job, assemble the permit file and run the schedule, while licensed subcontractors build, and you can request each one's license number and insurance certificate. Neighbors with their own guides are Santa Ana, about 4.1 miles west, Orange, about 5.1 miles north, Irvine, Costa Mesa and Newport Beach. Fountain Valley has no hub page yet, so call us about work there.

Tustin contractor and permit questions, answered
Who issues building permits in Tustin?
The City of Tustin does, through the Building Division of Community Development, which handles applications in its Citizen Self Service portal. Zoning and design review sit with Planning at 714-573-3140. The City says it collects fees only through the portal or at City Hall and never asks for a wire. We print no fee amounts.
What roof class does Tustin require?
Class B is the minimum under Ordinance 1569 for a new roof or one with more than half replaced in a year, outside the state fire zones. The City's older reroofing guide asks for Class A in the East Tustin hillside. That guide predates the 2025 codes, so ask the Building Division which applies to your street.
How tall can a fence be in Tustin?
Up to 6 feet 8 inches in general, with nothing over 3 feet in the required front yard setback, according to the City's fence guide. The City's code text we read comes from a Zoneomics mirror and not the official code. Fences at a driveway or street corner also face sight distance limits, so confirm your lot with Planning.
Do a fence, a shed or a low deck need a permit in Tustin?
It depends on which City document you read. Ordinance 1569 exempts fences to 6 feet and small sheds of 120 square feet or less. The City's FAQ says every shed and any fence over 3 feet needs one, and an older guide exempts low decks. Ask the Building Division at 714-573-3130 first.
How long does a Tustin building permit last?
The City's documents give three answers: 180 days unless work is active, void if not started within 360 days, and under Ordinance 1569 12 months to start and 180 days of suspension. The City page calls the ordinance proposed, yet the council packet shows adoption on November 18, 2025. Ask the Building Division which clock applies.
Do I need approval for exterior work in Old Town Tustin?
Usually yes. The Cultural Resources District requires a Certificate of Appropriateness for exterior alterations that need a building permit, and the City says any window replacement needs one. Ordinary maintenance that changes nothing is excepted. We have not read the Old Town design guidelines, so call Planning before ordering materials or choosing colors.
Can I build an ADU in Tustin?
Yes, state law allows ADUs and the City publishes size and setback rules. Its Ordinance 1517 dates to 2021, and the state housing department wrote in February 2026 that it may be out of date. Whether Ordinance 1578 was adopted is unverified, so ask Planning for the current standards before you design anything.
Are the prices on the Tustin pages quotes from MDG Builders?
No. They are Los Angeles planning ranges with their sources named on each trade page, and none is a Tustin quote or includes a permit fee. A real number comes only from our written proposal, after we visit the property and learn which overlay, soil or roof rule applies to your address.
Send MDG Builders your Tustin address
Tell us the neighborhood, whether Old Town, Tustin Ranch, Tustin Legacy, East Tustin or a 1960s tract, roughly when the house was built and whether an HOA is involved. We check the overlay and soils questions first, then the roof class and fence limits, before any plans are drawn.
