Whole Home Remodeling in Tustin
Whole home remodeling in Tustin draws a specific kind of homeowner to us: someone who has already decided to stay put and wants the house to finally work the way they need it to. Tustin’s housing stock spans nearly a century, and the gap between what these homes look like on the outside and what they need on the inside is often wide. A pre-war bungalow in Old Town might carry original knob-and-tube wiring and a floor plan built for a different era of family life. A 1960s ranch in Tustin Meadows might have load-bearing walls sitting exactly where an open layout wants to go. A two-story Tustin Ranch house from the 1990s might need every finish, fixture, and system brought forward at once.
A whole home remodel is one coordinated project, not a series of separate jobs. We move walls, update plumbing and electrical through licensed subcontractors we coordinate, reconfigure the floor plan, and rebuild finishes across multiple rooms, all under a single permit pulled through the City of Tustin Building Division. If your home sits in Old Town, that process also runs through the Cultural Resources District design review, which adds steps we plan for from the start.

Our Whole Home Remodeling Process in Tustin
A whole home remodel in Tustin starts before a single wall comes down. We walk the entire house, not just the rooms on your list. The attic, the crawl space or slab, the electrical panel, the supply lines, every part of the structure gets a look. For older homes in the Old Town core, where bungalows dating to the 1920s and 1930s are common, that first walk-through often turns up textured ceilings that may contain asbestos, framing that was altered at some point without documentation, or plumbing that has been partially updated over several decades. Where something is in doubt, we investigate before we draw anything: a sewer camera, asbestos testing, a structural assessment of the framing. For a 1980s or 1990s Tustin Ranch two-story, the issues shift toward HVAC routing, second-floor load paths, and Title 24 energy compliance, but the approach is the same.
Once we know what we are working with, we draw the existing house and your proposed layout in the same plan set. Structural engineering and Title 24 energy documents go in with that set, so we submit one permit application to the City of Tustin Building Division rather than chasing approvals in stages. If your property is in Old Town, we account for the Cultural Resources District design review and the certificate of appropriateness that overlay requires. Cabinets, tile, flooring, and fixtures for every room are selected at our design center in Fullerton before demolition begins, so materials are ready when construction reaches that phase.
Construction follows a fixed sequence: demolition, structural work, rough plumbing, electrical, and HVAC, then inspections, insulation, drywall, and finishes. Because every trade works from one coordinated plan, the plumber reroutes lines once and the finish flooring runs continuously through the house without a threshold marking where an old project stopped. One project manager carries the job from that first walk-through to final inspection.

A whole home remodel in Tustin is almost always a full building permit with plan check, because the work touches structure, plumbing, electrical and mechanical systems at the same time. All of that goes through the City of Tustin Building Division, which reviews plans and schedules inspections at key stages of the project. One factor worth knowing early: if your house sits inside Old Town, it falls under the Cultural Resources District overlay established in 1988. That overlay requires design review and a certificate of appropriateness before exterior changes are approved, which can shape your material choices, setbacks and the overall review path. We check that against your scope at the very start of planning, since it is far easier to design around those requirements than to revise plans after submission.
The age of the house drives most of what we find once work begins. Homes built before 1978 may contain lead-based paint, and federal law requires contractors who disturb it to follow the EPA Renovation, Repair and Painting rule; Horizon is an EPA Lead-Safe Certified Firm. Popcorn ceilings, certain older resilient flooring and duct insulation wrap from the same era can contain asbestos, so suspect materials are tested before demo begins and any confirmed asbestos removal goes to a licensed abatement contractor. Galvanized supply lines and undersized electrical panels show up regularly in the pre-war Old Town bungalows and the 1960s ranch tracts of Tustin Meadows alike, and a whole home remodel is the right time to replace them while the walls are already open.
Two state requirements come up on nearly every project. California Civil Code 1101.4 requires that older high-flow toilets, showerheads and faucets be replaced with water-conserving fixtures on many permitted remodels of homes built before 1994, so we build that into the fixture schedule from the start rather than catching it at final inspection. California’s Title 24 energy code applies to remodels as well as new construction, and the 2025 standards govern permits filed on or after January 1, 2026. New windows, insulation, lighting and any HVAC changes all have to comply, and we prepare the compliance documentation as part of the plan set.
Structure is the other major variable, particularly in older homes. Removing a load-bearing wall to open a kitchen to the living area means an engineered beam, posts and sometimes new or reinforced footings below. Raised-floor houses common in Old Town may also benefit from foundation bolting and cripple-wall bracing while the work area is exposed. Unpermitted additions, enclosed patios and garage conversions from past decades are common across Tustin’s housing stock, and the city typically requires those to be legalized, brought up to current code or rebuilt before it will sign off on the broader remodel. If additional living space is part of the goal, state law allows an ADU on most single-family lots, and it can be planned alongside the remodel to consolidate permitting and construction into a single coordinated project.

Why Choose Horizon Remodeling For Whole Home Remodeling in Tustin
Homeowners in Tustin hire us for whole home remodeling because a project of that scale needs a contractor whose license actually covers it. A Class B general building license is built for jobs that cross multiple trades, involve structural work, and move through a single permit process. We have held that license since 2009, and we carry a contractor’s bond. That foundation matters when walls are coming down, load paths are changing, and several trades need to coordinate on the same schedule.
The design-build structure we use makes that coordination easier to manage. The drawings, engineering coordination, permits, and construction all sit under one contract with one project manager on our end. You are not relaying information between an architect, a separate engineer, and individual trade contractors who have never met each other. The people who worked out your floor plan are in direct contact with the crew building it, which reduces the gaps where details get missed or costs shift unexpectedly. Finishes across every room are selected together, so the kitchen, bathrooms, and flooring stay visually consistent from one end of the house to the other.
We are also straightforward about the parts of a whole home remodel that homeowners sometimes do not hear until mid-project. Older housing stock in Tustin frequently has conditions behind the walls that need to be addressed before finish work begins. We talk through those realities early, including what can reasonably wait and what cannot, so your budget and schedule reflect the actual job rather than a best-case version of it.

Whole Home Remodeling FAQ
How is a whole home remodel different from a regular home remodel?
A typical remodel updates one room while the rest of the house stays untouched, but a whole home remodel treats the house as a single system. Walls come down, floor plans change, and plumbing, electrical, and HVAC are updated throughout, all drawn, permitted, and sequenced together so trades move through once without reopening finished work later. In Tustin, where the housing stock ranges from compact Old Town bungalows to sprawling Tustin Ranch two-stories, that coordinated approach matters because the scope and structural conditions vary widely from one era of construction to the next.
What's the difference between a whole home remodel and a complete home renovation?
The two terms overlap more than most people realize. A remodel typically focuses on changing the layout and updating finishes, while a renovation focuses on restoring what the house already has: structure, windows, plumbing, wiring, and heating and cooling systems. In practice, most whole home remodeling projects in Tustin involve both, especially in older Old Town bungalows where the bones need attention before anyone talks about countertops. We scope them together, addressing anything that protects the house first, then systems that are hard to reach once the walls close, then the finishes you see every day.
Do we have to move out during a whole home remodel?
It depends on the scope of work. If we are pulling out every bathroom and the kitchen at the same time, or taking floors and drywall down throughout the house, most families move out for at least the heaviest phases of construction. In a larger Tustin Ranch two-story that can stretch across several rooms, that disruption adds up quickly. If the project can be phased, keeping one bathroom functional and setting up a temporary kitchen, some homeowners stay put, though phasing adds time to the schedule. We walk through that trade-off once the plan is drawn.
How long does a whole home remodel take?
A whole home remodel typically runs several months in construction alone, and the full timeline from first drawings to move-in is often twice that once you factor in design, selections, and plan check. If your home is in Old Town Tustin, the Cultural Resources District overlay adds a design review and certificate of appropriateness step that can extend the front end further. Structural work, additions, or surprises behind the walls stretch the schedule too. We build a timeline specific to your house into every proposal, and starting drawings early is the single biggest factor in shortening the wait.
Who handles the permit for a whole home remodel in Tustin?
We handle the permit from start to finish. For a whole home remodel in Tustin, that means preparing the plan set, including structural engineering and Title 24 energy documents, submitting everything to the City of Tustin Building Division, and responding to plan-check comments until the permit is issued. During construction we schedule and attend every required inspection, and we close out the permit at final. If your home is in Old Town Tustin, where the Cultural Resources District overlay may require design review and a certificate of appropriateness, we build that extra step into the schedule from the beginning.
What drives the cost of a whole home remodel?
Cost is driven mainly by how much of the structure you are changing, what the house needs mechanically, and how you finish it out. Removing a load-bearing wall, relocating a kitchen or bathroom on a slab foundation, repiping, rewiring, panel upgrades, and any lead or asbestos handling all add to the base cost before you pick a single fixture. Homes in Old Town Tustin can carry additional design review requirements that affect both scheduling and scope. Finish level matters too. Two houses of the same square footage can land far apart in total cost, which is why our proposals break every item out line by line and separate the must-do work from the choices you get to make.
