Whole Home Remodeling in Lemon Heights
Whole home remodeling in Lemon Heights draws a specific kind of homeowner to our phone: someone who already loves the lot, the views, and the quiet of the North Tustin hills, but has run out of patience with a floor plan that no longer makes sense. These houses were built across several decades, from the citrus-era parcels of the 1920s through the custom hillside construction that continued into the mid-twentieth century. At three thousand square feet or more, spread across four or five bedrooms on a large sloped lot, the bones are usually solid. What tends to fall short is how the interior lives day to day, cramped circulation between the kitchen and main living areas, outdated plumbing and wiring that predate modern load demands, rooms sized for a different era.
A whole home remodel addresses all of that under a single project. We move walls to open the floor plan, coordinate plumbing and electrical updates through appropriately licensed subcontractors, and pull one permit that covers the full scope of work. Because Lemon Heights sits in unincorporated Orange County rather than the City of Tustin, permits run through OC Development Services, and the North Tustin Specific Plan adds a layer of land use and height requirements on top of standard county zoning. We account for both from the start, so the design process does not stall once it reaches the county.

Our Whole Home Remodeling Process in Lemon Heights
A whole home remodel in Lemon Heights starts before any drawings are made. We walk every part of the house, not just the rooms on your list. That means the attic, the crawl space or slab, the electrical panel, and the supply lines. On a custom hillside house built in the 1940s or 1950s, we frequently find framing that was modified by a previous owner, galvanized supply lines past their service life, or textured ceilings that test positive for asbestos. We look at those conditions first, and where something is uncertain we investigate before we draw, using a sewer camera, material testing, or a structural review as the situation calls for it. Surprises found on paper are cheap. Surprises found during demolition are not.
Once we understand what the house actually is, we draw the existing layout and the proposed new one in the same document. Structural engineering and Title 24 energy calculations go into that same plan set, which we submit as a single permit application to OC Development Services. Because these large hillside parcels fall inside the North Tustin Specific Plan, the county reviews the project against both the zoning code and the specific plan standards for height and land use, so a complete and coordinated submittal matters. Selections for cabinets, tile, flooring, and fixtures for every room are made at our design center in Fullerton before demolition begins, so materials are on order while the permit is in review.
Construction follows a fixed sequence: demolition first, then structural work, then rough plumbing, electrical, and HVAC, then inspections, insulation, drywall, and finishes. Because the entire house is permitted as one project, the plumber reroutes lines once through the finished path and the flooring runs continuously from room to room without the thresholds and height mismatches that appear when additions or partial remodels are layered on top of each other over the years, as is common in the older custom homes throughout this area. One project manager carries the job from that first walk-through to the final county inspection and the walkthrough with you at the end.

A whole home remodel in Lemon Heights moves through OC Development Services, not the City of Tustin, because the area is unincorporated county territory. That distinction matters from the first phone call. The permit is almost always a full building permit with plan check, because the scope touches structure, plumbing, electrical and mechanical work together. On top of the standard county zoning code, most of Lemon Heights sits inside the County of Orange North Tustin Specific Plan, which adds land use districts and height limits of its own. We review your scope against those requirements before any work is planned, because the Specific Plan can affect exterior materials, setbacks and the review path in ways that surprise homeowners who assumed county zoning was the only layer to satisfy.
The age of the housing stock is where the practical complexity lives. Homes built before 1978 may contain lead-based paint, and any contractor who disturbs it must follow the EPA Renovation, Repair and Painting rule. Horizon is an EPA Lead-Safe Certified Firm, so we handle that requirement as part of normal operations rather than as an afterthought. Popcorn ceilings, certain resilient flooring and older duct wrap installed through the mid-twentieth century can contain asbestos. We treat those materials as suspect until tested, and any confirmed removal goes to a licensed abatement contractor before our crews open the area further. Galvanized supply lines and undersized electrical panels show up regularly in houses of that era. A whole home remodel, with walls already open, is the right time to address both, and the permit process will typically require it.
Two California rules come up on nearly every whole house job in this area. 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 discovering it at final inspection. Title 24 energy standards apply to remodels as well as new construction. New windows, insulation, lighting and any mechanical changes all have to comply, and we prepare the energy compliance documents as part of the plan set.
Structure is the other variable that shapes the budget and the timeline on custom hillside houses. Removing a load-bearing wall to connect a kitchen and living area means an engineered beam, posts and sometimes new footings, all of which require engineering documents and inspection. The raised-floor construction common in this part of North Tustin also creates an opportunity: while the work area is open, foundation bolting and cripple-wall bracing can be added to improve seismic performance in a cost-effective way. Unpermitted additions, enclosed patios and garage conversions from earlier decades are common on these large lots, and OC Development Services will typically require them to be legalized, upgraded or rebuilt before signing off on the rest of the house. If additional living area is part of your goal, state law allows an accessory dwelling unit on most single-family parcels, and planning it alongside the primary remodel keeps the permit process and the construction work coordinated.

Why Choose Horizon Remodeling For Whole Home Remodeling in Lemon Heights
Homeowners in Lemon Heights tend to have older properties with character worth keeping and square footage worth improving. A whole home remodel touches the kitchen, bathrooms, living areas, and often the structure itself, which means electrical, plumbing, framing, and finishes all need to move together. That is exactly the kind of project a Class B General Building license covers, and it is the kind of work we have been doing since 2009. Horizon Construction and Remodeling is licensed and bonded, and our focus has always been projects that cross multiple trades under a single contract.
The design-build approach matters more on a whole home remodel than on any other job. The drawings, engineering coordination, permits, and construction all sit under one agreement with one project manager. You are not relaying decisions between an architect, a separate engineer, and individual trade contractors. The people who worked out the floor plan are in direct contact with the crew building it, which reduces the gaps where details get lost or costs climb without explanation. Finishes for every room are selected together, so the kitchen, bathrooms, and flooring read as one cohesive project rather than a series of independent choices.
We are also straightforward about the things homeowners in Lemon Heights and across Southern California sometimes find uncomfortable to hear: whether living in the house during construction is actually realistic, what an older home is likely to need once walls open up, and which upgrades can reasonably wait without creating bigger expenses later. Honest answers early save significant frustration once work begins.

Whole Home Remodeling FAQ
How is a whole home remodel different from a regular home remodel?
A typical remodel focuses on one room or area while leaving the rest of the house alone, but a whole home remodel treats the house as a single system. Several rooms are addressed at once, walls are often moved or removed to change the floor plan, and plumbing, electrical, and HVAC are updated throughout. For the large custom houses common in Lemon Heights, that integrated approach means everything is drawn, permitted, and sequenced together, so trades come 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 two terms overlap more than most people realize. A remodel typically means changing the layout, adding space, or updating finishes, while a renovation focuses on restoring what the house already has: structure, windows, plumbing, wiring, and mechanical systems. In practice, most whole home remodeling projects in Lemon Heights involve both, because the custom hillside houses here often need structural and systems work before the finish work even starts. We scope them together, addressing anything that protects the building first, then the systems that become hard to reach once 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 the work. If the kitchen and every bathroom are being gutted at the same time, or demolition is running through most of the house at once, most families move out for at least the heaviest phases. Given the size of many homes in Lemon Heights, often four or five bedrooms across more than 3,000 square feet, phasing is sometimes possible, keeping one bathroom live and setting up a temporary kitchen in another room so the family can stay. Phasing does add time to the schedule, and 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 design through final inspection is often twice that or more. For a larger custom house in Lemon Heights, where plan check runs through OC Development Services and the North Tustin Specific Plan can add review layers, permitting alone may take several weeks. Structural work, additions, or surprises behind the walls stretch the schedule further. We build a project-specific timeline into every proposal, and starting drawings early is the single biggest factor in when you move back in.
Who handles the permit for a whole home remodel in Lemon Heights?
We handle the permits. For a whole home remodel in Lemon Heights, that means submitting to OC Development Services, because this area is unincorporated county territory inside North Tustin rather than part of the City of Tustin. Our team prepares the plan set, including structural engineering and Title 24 energy documents, responds to plan-check comments, and schedules every required inspection through final. Because many homes here also fall under the North Tustin Specific Plan, we account for those review layers from the start.
What drives the cost of a whole home remodel?
Cost is driven by the scope of structural and systems work your house actually needs, not just its square footage. Two homes the same size can land far apart in price. 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 move the number significantly. In Lemon Heights, where many custom homes are large and were built across several decades, the condition of existing systems varies widely. Finish level is the other major variable. Your proposal breaks everything out line by line.
