Whole Home Remodeling in Fullerton
Whole home remodeling in Fullerton draws a specific kind of homeowner: someone who has lived on their street long enough to know they are staying, but who has spent years working around a floor plan that was never quite right. Fullerton’s housing stock tells that story clearly. The pre-war bungalows and Spanish Colonial Revival houses in older neighborhoods were built with compartmentalized rooms, a tight kitchen, and a service porch that made sense in a different era. The postwar ranch houses that filled in the rest of the city after World War II have their own version of the same problem: a kitchen sealed off from the living room by a load-bearing wall, dated wiring, and plumbing that has never been touched since the Eisenhower administration.
A whole home remodel addresses all of that under a single project plan. We are talking about several rooms reworked at once, walls relocated to open up the floor plan, electrical and plumbing systems brought current, and one permit pulled to cover the scope. For properties that carry a local landmark designation, qualifying work also typically requires a Certificate of Appropriateness through the City of Fullerton’s Landmarks Commission process, and we account for that from the first walk-through. This is a fundamentally different undertaking than a single-room renovation, and we plan it that way.

Our Whole Home Remodeling Process in Fullerton
A whole home remodel in Fullerton starts long before anyone picks up a tool. We walk the entire house, not just the rooms on your wish list. That means the attic, the crawl space or the slab, the electrical panel, and the supply lines. In a pre-war bungalow or Spanish Colonial Revival, decades of patchwork can hide surprises behind lath-and-plaster walls or under an old service porch. Where something looks uncertain, we investigate before we draw. That might mean running a sewer camera, testing textured ceilings for asbestos common in mid-century finishes, or taking a structural look at framing someone rerouted years ago. If the home carries a local landmark designation, we also account for the Certificate of Appropriateness process through the Fullerton Landmarks Commission before the design is finalized.
Once we know what we are working with, we draw the existing house and the proposed layout in the same document. You review it and make changes on paper, where revisions cost nothing. Structural engineering and Title 24 energy calculations go into that same plan set, and we submit everything together to the City of Fullerton Building and Safety Division as one permit package. Before demolition begins, cabinets, tile, flooring, and fixtures for every room are selected at our design center in Fullerton, so material lead times do not stall construction later.
Construction follows a fixed sequence: demolition, structural work, rough plumbing, rough electrical and HVAC, inspections, insulation, drywall, and finishes. In a postwar ranch where the original layout kept the kitchen walled off from the living room, that single coordinated plan means the plumber reroutes lines once and the new flooring runs continuously through the open plan without a threshold marking where an old project stopped. One project manager carries the job from the first walk-through to the final inspection sign-off.

A whole home remodel in Fullerton moves through the City of Fullerton Building and Safety Division for permitting, and in most cases that means a full building permit with plan check. Because the work touches structure, plumbing, electrical and mechanical systems at the same time, the city treats it as a comprehensive project rather than a series of small trades. We prepare the drawings, submit the application and track the plan check on your behalf, so you are not navigating that process alone. One factor that does not come up in most cities is worth flagging early: Fullerton has a Landmarks Commission and a local landmark ordinance, and designated properties require a Certificate of Appropriateness before qualifying work can begin. We check your address against that list at the start of every project, because it can affect exterior materials, setbacks and the review path before a single wall comes down.
The age of the house shapes almost everything we find once work begins. Fullerton’s older neighborhoods along Golden Hill and Raymond Hills contain pre-war bungalows and Spanish Colonial Revival homes from the 1900s through the 1930s, and the postwar tract ranches that filled in the rest of the city after World War II are now well past the fifty-year mark themselves. Homes built before 1978 may contain lead-based paint, and federal EPA Renovation, Repair and Painting rules require certified firms to follow specific containment and work practices when that paint is disturbed. Popcorn ceilings, certain resilient flooring and older duct wrap can contain asbestos, so we test suspect materials before any demo begins and send confirmed asbestos to a licensed abatement contractor. Galvanized supply lines corrode from the inside out and restrict flow noticeably in houses of that era. Undersized electrical panels are just as common, and a whole home remodel is the practical time to address both, while the walls are already open.
Two state rules come up on nearly every whole house job in California. Civil Code Section 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 discovering it at final inspection. California’s Title 24 energy code applies to remodels as well as new construction, and the current standards govern insulation, windows, lighting and any HVAC changes included in the scope. We prepare the compliance documentation with the plans so that piece does not slow down the permit.
Structure is the other variable that surprises homeowners. Removing a load-bearing wall to open a walled-off kitchen to the living area, which is one of the most common requests we see in both the bungalow and the ranch floor plan, requires an engineered beam, posts and sometimes new footings below grade. Raised-floor homes may also benefit from foundation bolting and cripple-wall bracing while the work area is accessible. Unpermitted additions, enclosed patios and garage conversions are common throughout Fullerton, and the city typically requires those conditions to be legalized, brought up to current code or rebuilt before it will sign off on the rest of the remodel. If you need more living area on top of updating what you have, state law allows an accessory dwelling unit on most single-family lots, and coordinating the ADU with the remodel under one permit process is often the most efficient path forward.

Why Choose Horizon Remodeling For Whole Home Remodeling in Fullerton
Fullerton homeowners hire us for whole-home remodeling because a project that touches several rooms, multiple trades, and structural work is exactly what a Class B general building contractor is licensed to handle. One permit, one contract, and one project manager covering everything from framing to finish work means the job moves in a coordinated way rather than waiting on three separate parties to compare notes. We have held that license since 2009, and we carry a contractor’s bond, so the credentials behind the work are straightforward to verify.
The design-build approach is a practical advantage on a project this size. The drawings, engineering coordination, and permitting all sit under the same roof as the crew doing the construction. When the floor plan changes during framing, the people who drafted it already know about it. Finishes for every room are selected together, so the kitchen, bathrooms, and flooring read as one house rather than a series of unrelated decisions made months apart.
We are also direct about the things homeowners sometimes hear too late. Older houses in the area routinely have surprises behind the walls, and we talk through what is likely before work starts rather than after. We will tell you honestly whether living in the house during construction is realistic for your situation, and we can identify which items on your list can be phased later without driving up the overall cost when you do get to them.

Whole Home Remodeling FAQ
How is a whole home remodel different from a regular home remodel?
A typical remodel focuses on one room at a time, while a whole home remodel treats the entire house as a single project. Walls come down, floor plans change, and plumbing, electrical, and HVAC are updated throughout in one coordinated sequence. That matters in Fullerton, where many postwar ranch homes still have walled-off kitchens and original systems that need to be addressed together. Everything is drawn, permitted, and scheduled as one scope so trades move through once without reopening finished work later.
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 the layout or finishes, while a renovation focuses on restoring what the house already has: structure, windows, plumbing, wiring, and heating and cooling. In practice, most whole home remodeling projects in Fullerton involve both, especially in the older bungalows and ranch houses where systems are decades past their useful life. We scope everything together, addressing what protects the house first, then the systems that are 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?
It depends on the scope of work. If the kitchen and every bathroom are coming out at the same time, or drywall and flooring are being removed throughout the house, most families find it easier to move out for at least the heaviest phases of construction. In older Fullerton homes, where the kitchen and bathrooms are often compact and tightly connected, that overlap happens more than you might expect. If the project can be phased to keep one bathroom functional and a temporary kitchen in another room, some homeowners do stay. Phasing adds time to the schedule, so 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 that does not count design and permitting, which can take just as long. Plan check with the City of Fullerton Building and Safety Division can run several weeks on its own, and older homes in neighborhoods like Golden Hill or Raymond Hills sometimes reveal hidden conditions behind the walls that add time. We give you a project-specific schedule with your proposal, and starting drawings early is the biggest lever on your move-back-in date.
Who handles the permit for a whole home remodel in Fullerton?
We handle the permit from start to finish. For a whole home remodel, applications go through the City of Fullerton Building and Safety Division, and our team prepares the full plan set, including structural engineering and Title 24 energy documents, submits everything, and works through plan-check comments until the permit is issued. If your home is a designated local landmark, a Certificate of Appropriateness from the Fullerton Landmarks Commission may also be required, and we account for that in the project schedule. During construction we coordinate all required inspections and close out the permit at final.
What drives the cost of a whole home remodel?
Cost on a whole home remodel is driven by the complexity of the work, not just the square footage. Structural changes like removing a load-bearing wall or relocating a kitchen or bathroom add significant labor and engineering, and repositioning plumbing on a slab foundation is especially involved. Older Fullerton homes, particularly the pre-war bungalows and Spanish Colonial Revivals in neighborhoods like Golden Hill, often need repiping, rewiring, panel upgrades, or hazardous material handling before finish work even begins. Added square footage and the finish level you choose push costs further. Our proposals separate must-do items from optional upgrades so you can see exactly where the money goes.
