Whole Home Remodeling in La Habra
Whole home remodeling in La Habra is what most of our calls are about from homeowners who like their street, like their neighbors, and have no interest in moving, but are done living around a floor plan that stopped making sense years ago. The postwar ranch houses that fill neighborhoods like Arbolita and the streets near downtown were built for a different way of living. The kitchen was its own separate room, the hallways ate up square footage, and the bathrooms were sized for a different era. The hillside tracts in areas like Westridge and Country Hills East came later with more open plans, but those homes carry their own dated layouts and deferred updates.
A whole home remodel addresses the house as a single project rather than a series of disconnected fixes. We move walls to change how rooms connect, update the plumbing and wiring so the house meets current standards, and pull one permit through the City of La Habra Building and Safety Division that covers the full scope of work. That coordination is the difference between a real remodel and a series of patches, and it shapes how we plan the job from the first walk-through forward.

Our Whole Home Remodeling Process in La Habra
A whole home remodel in La Habra starts well before any drawings are made. We walk the entire house, not just the rooms you have in mind. That means the attic, the electrical panel, the supply lines, and the slab. Many of the postwar ranch homes in La Habra were built in the 1950s and 1960s, and decades of smaller repairs and additions can leave the framing altered in ways that are not obvious until someone looks carefully. Where something is in doubt, we investigate before we draw. That might mean a sewer camera, asbestos testing on textured ceilings common to that era, or a closer look at structural members that were cut or notched by a previous owner.
Once we know what the house is actually doing, we draw it. We produce a set of existing and proposed floor plans so you can move walls and openings on paper, where changes cost nothing. Structural engineering and Title 24 energy documents go into the same plan set, and the whole package goes to the City of La Habra Building and Safety Division as one submission. Before demolition begins, every cabinet, tile, fixture, and finish for every room is selected at our design center in Fullerton. That step matters because the two-story hillside plans in areas like Westridge often have an open kitchen and family room where finish decisions in one space directly affect how the next space reads.
Construction follows a fixed order: demolition, structural work, rough plumbing, electrical, and mechanical, then inspections, insulation, drywall, and finishes. Because it is one coordinated plan, the plumber reroutes lines once and the flooring runs through every room without the threshold seams that show up when projects are done in separate phases. One project manager carries the job from the first walk-through to final inspection.

A whole home remodel in La Habra almost always requires a full building permit with plan check, because the work touches structure, plumbing, electrical and mechanical systems at the same time. Permits for this scope go through the City of La Habra Building and Safety Division, which reviews drawings before work begins and schedules inspections at key stages through completion. One practical point worth knowing early: no unusual local overlay applies here, so the California Building Code and any applicable association rules are what govern your project. We check both against your scope at the start, since they can shape exterior material choices, setbacks or the review path before a single wall comes down.
The age of the house drives most of what we find once work begins. La Habra’s postwar ranch homes and the older properties near downtown were built through eras when lead-based paint and asbestos-containing materials were standard. Homes built before 1978 may have lead paint on walls, trim and windows, and contractors who disturb those surfaces must follow the EPA Renovation, Repair and Painting rule. Popcorn ceilings, some resilient flooring and older duct wrap can contain asbestos, so suspect materials are tested before any demolition, and removal is handled by a licensed abatement contractor. Galvanized supply lines and undersized electrical panels show up regularly in houses of that era, and a whole home remodel is the right time to address them while the walls are already open.
Two state requirements come up on nearly every whole house job in 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 include them in the fixture schedule at the design stage rather than discovering the requirement at final inspection. California’s Title 24 energy code applies to remodels as well as new construction, covering windows, insulation, lighting and HVAC changes. We prepare the compliance documents with the plans so the project moves through plan check without avoidable delays.
Structure is the other variable that surfaces regularly in La Habra’s housing stock. Opening a kitchen to a living or family room, which is a common goal in both the older ranch-style homes and the hillside two-story plans in areas like Westridge and Country Hills East, means an engineered beam, proper posts and sometimes new footings. Unpermitted additions, enclosed patios and garage conversions are common in homes of this age, and they typically need to be legalized, brought up to current standards or rebuilt before the city will sign off on the broader remodel. If additional living space is part of the plan, state law allows an ADU on most single-family lots, and coordinating that alongside the main remodel can simplify both the permit process and the construction schedule.

Why Choose Horizon Remodeling For Whole Home Remodeling in La Habra
La Habra homeowners tend to hire us for whole home remodeling because the scope of that work matches exactly what a Class B general building contractor is licensed to do. Structural changes, multiple trades, and a single permit package are the core of a Class B project, and that is where we are most useful. Horizon Construction and Remodeling has been doing this work since 2009, and we are licensed and bonded.
One reason clients tell us the process felt manageable is that we operate as a design-build contractor. The drawings, engineering coordination, permits, and construction all sit under one contract with one project manager on your side. You are not passing messages between an architect, a separate engineer, and independent trade contractors. The people who worked out the floor plan are in direct contact with the crew executing it, which cuts down on the gaps where things go wrong. Finish selections for every room, kitchen, baths, flooring, and everything in between, are worked out together, so the house reads as a coherent whole rather than a collection of separate projects.
We also try to be straightforward about the parts of a remodel that homeowners do not always want to hear. Older homes in the area frequently need work behind the walls that does not show up in the finished product. We will tell you early whether living in the house during construction is realistic for your situation, and which items can reasonably wait without costing more down the road.

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 structure as a single system. Several rooms are updated at once, walls are moved or removed to reshape the floor plan, and plumbing, electrical, and HVAC are brought up to date throughout. For the postwar ranch homes common across La Habra, that often means opening the separate kitchen into the living area. Everything is drawn, permitted, and sequenced together so trades move through once instead of reopening finished work on a later project.
What's the difference between a whole home remodel and a complete home renovation?
The terms overlap more than most people realize. A remodel typically means changing the layout or finishes, while a renovation focuses on restoring the house itself: structure, windows, plumbing, wiring, and mechanical systems. Most whole home projects in La Habra end up being a mix of both, especially in the postwar ranch homes where original systems are due for replacement. We scope everything together, addressing what protects the house first, then the systems buried inside walls, 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 entirely on the scope of your remodel. If the kitchen and every bathroom are being torn out at the same time, or drywall and floors are coming out throughout the house, most families find it easier to relocate for the heaviest phases of work. If the project can be phased to keep one bathroom functional and a temporary kitchen set up elsewhere, staying home is sometimes possible. Phasing adds time to the schedule, so we work through that trade-off with you 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 design and permitting often take just as long before a crew ever sets foot inside. Plan check at the City of La Habra Building and Safety Division can run several weeks on its own. Older postwar ranch homes in La Habra sometimes reveal surprises behind the walls that add time. We build a project-specific schedule into every proposal, and starting your drawings early is the single biggest factor in how soon you move back in.
Who handles the permit for a whole home remodel in La Habra?
We handle the permit from start to finish. For a whole home remodel in La Habra, that means preparing the plan set, including structural engineering and Title 24 energy documents, submitting everything to the City of La Habra Building and Safety Division, and responding to plan-check comments until the permit is issued. During construction we schedule and attend all required inspections and close out the permit at final. If your neighborhood, such as Westridge or Country Hills East, has HOA rules that apply, we build that review into the schedule as well.
What drives the cost of a whole home remodel?
Cost is driven by the scope of structural and mechanical work your house actually needs, not just its square footage. Moving a kitchen or a bathroom on a slab foundation adds real money because the concrete has to be opened for drain relocation. Older postwar ranch homes in La Habra frequently need panel upgrades, repiping, or hazardous material handling before finish work can even begin. Load-bearing wall removal, added square footage, and the finish level you select all move the number significantly. Our proposals break every item out line by line so you can see what is required and what is a choice.
