Whole Home Remodeling in Santa Ana
Whole home remodeling in Santa Ana draws homeowners who genuinely like their neighborhood but have outgrown the way their house is laid out. A lot of the calls we get come from owners of single-story Craftsman cottages near French Park or Washington Square, Spanish Colonial Revival homes in Floral Park, and postwar ranch houses in the tracts that filled in through the 1950s and 1960s. These are solid homes on good lots, but they were designed for a different era, and the floor plans, plumbing, and wiring often show their age.
A whole home remodel addresses that all at once. Rather than redoing one room and living with the rest, we plan a single project that may move walls to open up the floor plan, update the plumbing and electrical systems through licensed subcontractors we coordinate, and bring the home in line with current Title 24 energy requirements. One permit covers the scope, which keeps inspections organized and the schedule predictable. In historic districts like Floral Park and French Park, alterations typically also require a Certificate of Appropriateness, and we build that review process into the timeline from the start.

Our Whole Home Remodeling Process in Santa Ana
A whole home remodel in Santa Ana starts before any drawings are made. We walk the entire house, not just the rooms on your list. That means the attic, the crawl space or slab, the electrical panel, and the supply lines. In the older Craftsman and Spanish Colonial Revival cottages around downtown, framing has often been altered over the decades, and we look at that carefully before we commit anything to paper. If a ceiling has the texture common in postwar construction, we test it before disturbing it. A sewer camera can answer questions about original clay lines that nobody wants to discover mid-project. Asbestos screening, structural review, a methodical look at what is actually there rather than what the original plans assumed, all of that investigation happens first, because surprises found on paper cost far less than surprises found in the wall.
Once we understand the house, we draw it as it exists, then draw what you want it to become. You review the layout on paper, where moving a wall is a line and an eraser rather than labor and drywall. Structural engineering and Title 24 energy compliance documents are prepared as part of the same plan set and submitted together to the City of Santa Ana Building Safety Division as a single permit application. If your home falls within a designated historic district such as Floral Park or French Park, alterations will also require a Certificate of Appropriateness reviewed against the Secretary of the Interior’s Standards, and we account for that review in the schedule from the start. Cabinets, tile, flooring, and fixtures for every room are selected at our design center in Fullerton before demolition begins, so materials are confirmed before a wall comes down.
Construction follows a fixed sequence: demolition first, then structural work, then rough plumbing, electrical, and HVAC, followed by inspections before insulation and drywall close everything in. Because the entire house is on one plan, the plumber reroutes lines once and the new flooring runs continuously through rooms without the threshold that marks where an old project ended and the original house began. One project manager oversees the work from that first walk-through through final inspection, coordinating the licensed subcontractors who handle the specialty trade portions and keeping the schedule moving between stages.

A whole home remodel in Santa Ana almost always requires 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 Santa Ana Building Safety Division, part of the city’s Planning and Building Agency. Before we submit anything, we also check whether your property falls inside one of the city’s designated historic districts. Floral Park and French Park are two of the areas covered, and alterations there require a Certificate of Appropriateness reviewed against the Secretary of the Interior’s Standards. That review can shape exterior materials, setbacks and the approval path, so we sort it out at the very beginning rather than discovering it after a wall comes down.
The age of the housing stock in Santa Ana is the biggest driver of what we find once work begins. The tracts around downtown were largely built before World War II, and the outlying neighborhoods filled in through the 1950s and 1960s. That means most houses we work on in areas like Washington Square or Heninger Park are old enough to carry real hazards. Homes built before 1978 may have lead-based paint, and any contractor who disturbs it must follow the EPA Renovation, Repair and Painting rule. Popcorn ceilings, certain flooring materials and older duct wrap can also contain asbestos, so we test suspect materials before disturbing them and send any confirmed material to a licensed abatement contractor. Galvanized supply lines corrode from the inside out over decades, and undersized electrical panels are a consistent finding in houses of this era. A whole home remodel is the practical moment to address both, while the walls are already open.
Two state requirements show up on nearly every whole house job regardless of neighborhood. California Civil Code 1101.4 requires older high-flow toilets, showerheads and faucets to 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, covering new windows, insulation, lighting and HVAC changes, and we prepare the compliance documents as part of the plan set.
Structure is its own chapter. Opening the kitchen to the living area in a prewar Craftsman or a postwar ranch plan typically means an engineered beam, new posts and sometimes upgraded footings below. Raised-floor houses common to this region can also benefit from foundation anchor bolting and cripple-wall bracing while the work area is already exposed. Unpermitted additions and enclosed patios are a recurring find in older Santa Ana homes, and the city will require that work to be legalized, brought up to code or rebuilt before it will sign off on the rest of the project. If additional square footage is part of your goals, state law allows an accessory dwelling unit on most single-family lots, and planning it alongside the remodel keeps the permit process consolidated.

Why Choose Horizon Remodeling For Whole Home Remodeling in Santa Ana
Santa Ana homeowners 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 structured for jobs that cross multiple trades, involve structural work, and move through the permitting process as a single coordinated effort. That is exactly what a whole home remodel is, and it is the kind of work we have been doing since 2009.
Our approach puts drawings, engineering coordination, permits, and construction under one contract with one project manager. You are not passing information between an architect, a separate engineer, and individual trade crews. The people who worked out the floor plan are in direct contact with the crew executing it, which reduces the gaps where details get lost. Finishes for every room, kitchen, bathrooms, flooring, and everything in between, come together at our design center in Fullerton, so the selections stay consistent across the whole house rather than looking like separate decisions made at separate times.
We are also straightforward about the parts of a remodel that are easy to gloss over. We will tell you honestly whether living in the house during construction is realistic for your situation, what an older home is likely to need once walls are open, and which items on your list can be deferred without creating bigger costs down the road. That kind of honesty is part of working with a contractor who is licensed and bonded and has been doing this work in Southern California for over fifteen years.

Whole Home Remodeling FAQ
How is a whole home remodel different from a regular home remodel?
A typical remodel focuses on one room while the rest of the house stays put, but a whole home remodel treats the entire structure as a single project. Walls come down, floor plans change, and plumbing, electrical, and HVAC are updated throughout in one coordinated effort. Everything is drawn, permitted, and sequenced together, so trades move through once instead of tearing into finished work later. In older Santa Ana neighborhoods, that unified approach also makes it easier to manage any historic review requirements from the start.
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 generally means changing layouts and finishes, while a renovation focuses on restoring what the house already has: structure, windows, plumbing, wiring, and mechanical systems. Most whole home remodeling projects in Santa Ana end up being both, especially in the older Craftsman cottages and postwar ranch homes where the bones are sound but the systems are well past their useful life. We scope everything together, addressing what protects the house first, then the systems that become hard to reach once walls close, then the finishes you live with every day.
Do we have to move out during a whole home remodel?
Whether you need to move out depends on the scope of the remodel and how the work is phased. If the kitchen and every bathroom are being torn out at the same time, or drywall and flooring are coming out through the whole house, most families find it easier to relocate for at least the heaviest part of construction. In smaller single-story homes, which make up much of Santa Ana’s housing stock, there is often less flexibility to section off a livable area. When phasing is possible, keeping one bathroom operational and setting up a temporary kitchen in another room can let some families stay, though phasing does add time to the overall schedule. We walk through that trade-off with you once the plan is drawn.
How long does a whole home remodel take?
A whole home remodel typically takes several months of construction, and that number grows when structural work, an addition, or surprises behind the walls come into the picture. Design and plan check can take just as long as the build itself, and review at the City of Santa Ana Building Safety Division can run several weeks on its own. We put a schedule specific to your house in the proposal, and starting drawings early is the single biggest lever on your move-back-in date.
Who handles the permit for a whole home remodel in Santa Ana?
We handle the permit from start to finish. For a whole home remodel, applications go through the City of Santa Ana Building Safety Division, part of the city’s Planning and Building Agency. We prepare the full plan set, including structural engineering and Title 24 energy documents, submit it, and respond to plan-check comments until the permit is issued. If your home sits in a designated historic district like Floral Park or French Park, we factor the Certificate of Appropriateness review into the schedule from the beginning. Throughout construction we schedule and attend every required inspection, then close out the permit at final.
What drives the cost of a whole home remodel?
Cost varies widely even between two houses of the same size, so we never publish a standard price range. The biggest drivers are structural changes such as removing a load-bearing wall, relocating a kitchen or bath on a slab foundation, how much repiping, rewiring, and panel work the house needs, any lead or asbestos remediation, added square footage, and the finish level you choose. In older Santa Ana neighborhoods, those factors come up often. Your proposal breaks everything out line by line, separating required work from optional upgrades.
