Whole Home Remodeling in San Gabriel
Most homeowners who ask us about whole home remodeling in San Gabriel are happy with their neighborhood but frustrated with how their house actually functions. San Gabriel incorporated as a mission town in April 1913 with around 1,500 residents, and most of the housing stock that fills its modest valley lots arrived in the mid to late twentieth century, meaning many of these single-family homes and small multi-unit buildings carry the layouts, wiring, and plumbing of a different era. A whole home remodel addresses all of that in one coordinated project: rooms reworked together, walls moved to open the floor plan, and mechanical systems brought current, with permits issued through the City of San Gabriel covering the full scope rather than one trade at a time. That is a fundamentally different undertaking than a single-room update, and we approach the planning accordingly from the first walk-through.

Our Whole Home Remodeling Process in San Gabriel
Whole home remodeling in San Gabriel begins long before any wall comes down. We walk the entire house first, from the attic to the slab or crawl space, checking the electrical panel, supply lines, and anything else that could create a problem mid-project. Homes here were mostly built in the mid-to-late twentieth century, and that age often means textured ceilings worth testing for asbestos, framing that has been altered over the decades, and plumbing that needs a camera before we commit to a layout. Once we know what we are working with, we draw the existing house and the proposed layout together so changes happen on paper, where they are still inexpensive. Structural engineering and Title 24 energy documents go into a single plan set submitted to the City of San Gabriel for one building permit.
After permit approval, construction follows a fixed sequence: demolition, structural work, rough plumbing, electrical, and mechanical, then inspections, insulation, drywall, and finishes. Because all trades work from one coordinated plan, plumbing lines are rerouted once and flooring runs continuously through every room. One project manager oversees the work from the first inspection to the final walkthrough.

Whole home remodeling in San Gabriel almost always means a full building permit with plan check, because the work touches structure, plumbing, electrical and mechanical systems at the same time. Permits go through the City of San Gabriel, which issues building permits for work inside city limits. No unusual local overlay applies here, so what actually governs the project is the building code and the age of the house itself. We review both against your scope early on, because that review shapes exterior material choices, setback questions and the plan-check path well before any walls come down.
The age of the housing stock matters in a practical way. San Gabriel grew steadily through the middle and later twentieth century, and many of the single-family homes and small multi-unit buildings on valley lots in areas like the Vincent Lugo Park neighborhood or near the Broadway blocks around Smith Park were built in eras when materials and systems were very different from today’s standards. Homes built before 1978 may contain lead-based paint, and any work that disturbs it must follow the EPA Renovation, Repair and Painting rule. Suspect materials such as popcorn ceilings, older flooring and duct wrap are tested before work begins, and any abatement goes to a licensed specialty contractor. Galvanized supply lines and undersized electrical panels also 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 job. 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 that in 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, covering new windows, insulation, lighting and HVAC changes, and we prepare the compliance documentation as part of the plan set.
Structure adds another layer of planning. Removing a load-bearing wall to open up a kitchen or living area typically requires an engineered beam, posts and sometimes new footings. Unpermitted additions, enclosed patios and garage conversions are common across the city, and they need to be legalized, upgraded or rebuilt before the city will sign off on the broader project. If additional square footage is the goal, state law allows an ADU on most single-family lots, and it can be planned alongside the remodel from the beginning.

Why Choose Horizon Remodeling For Whole Home Remodeling in San Gabriel
Horizon Construction and Remodeling has held an active Class B general building contractor license since 2009, and we are licensed and bonded. A whole home remodel is exactly the kind of work that license covers: multiple trades, structural coordination, and a single permit pulled through one contractor of record. In San Gabriel, that permit goes through the City of San Gabriel, and because no unusual local overlay applies, the building code and the age of the house are the two things that govern what the scope looks like on paper.
Most homes in San Gabriel are single-family houses built during the mid to late twentieth century, and behind the walls of a house that age there is often wiring, plumbing, or framing that has to be addressed before finish work can start. We are direct about that from the beginning. We tell you what the house likely needs, which items can reasonably wait, and whether living on site during construction is a practical plan for your specific layout and timeline.
Our process runs under one contract with one project manager handling drawings, trade coordination, inspections, and construction. The people working through the design are communicating directly with the crew building it, so nothing gets lost between planning and execution. Finishes across every room are selected together, keeping the kitchen, bathrooms, and living spaces consistent throughout the house.

Whole Home Remodeling FAQ
How is a whole home remodel different from a regular home remodel?
A whole home remodel treats the house as one connected system rather than a series of separate jobs. Instead of updating one room while the rest stays put, several spaces are redesigned at once, walls are moved or removed to reshape the floor plan, and plumbing, electrical, and HVAC are updated throughout. In San Gabriel, where a large share of the housing stock dates to the mid-twentieth century, that kind of comprehensive scope is often what it takes to bring an older single-family home in line with how a household actually lives today. Every scope item is drawn, permitted through the City of San Gabriel, and sequenced together, so the 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?
A remodel changes layouts and finishes, while a renovation restores what the house is built from, covering structure, windows, plumbing, wiring, and heating and cooling systems. In practice, most whole home remodeling projects in San Gabriel combine both, especially in the mid-century single-family homes that make up a large share of the city’s housing stock. We scope them together, addressing anything that protects the structure first, then systems hidden behind walls, then the finishes you live with every day.
Do we have to move out during a whole home remodel?
The honest answer is that it depends on how much work is happening at once. Homes along the Broadway blocks near Smith Park or anywhere else in San Gabriel tend to follow the same pattern: if the kitchen and every bathroom are being gutted together, or floors and drywall are coming out throughout the house, most families find it easier to move out during the heaviest phases. Phased work, where one bathroom stays functional and a temporary kitchen is set up, lets some households stay put, though phasing does add time to the overall schedule, and we walk through that trade-off once the plan is drawn.
How long does a whole home remodel take?
How long a whole home remodel in San Gabriel takes depends on the scope of work, how fast plan check moves, and how quickly you lock in your selections. The City of San Gabriel issues building permits for work inside city limits, and plan check alone can run several weeks or more, often matching the length of construction itself. For a typical single-family house in the valley, construction runs several months, and structural work or hidden conditions behind the walls push that further. We put a project-specific schedule in your proposal, and getting drawings started early is the single biggest factor in shortening your time out of the house.
Who handles the permit for a whole home remodel in San Gabriel?
Yes, we handle permits for whole home remodeling in San Gabriel from start to finish. Our team prepares the full plan set, including structural engineering and Title 24 energy documents, then submits everything to the City of San Gabriel and responds to plan-check comments until the permit is issued. We schedule and attend all required inspections during construction and close out the permit at final. Many older homes along corridors like Valley Boulevard carry decades of deferred work, so we build realistic timelines from the beginning.
What drives the cost of a whole home remodel?
Whole home remodeling costs in San Gabriel vary widely, and two houses of similar square footage can land far apart in price, so we do not publish ranges. The biggest cost drivers are structural changes such as removing a load-bearing wall, relocating a kitchen or bathroom on a slab foundation, the extent of repiping and rewiring the house needs, hazardous material handling, added square footage, and finish level. Many homes in San Gabriel date to the mid-twentieth century, which means the age of the structure often shapes what the building code requires before anything else can move forward. Every proposal we put together breaks all of that out line by line, separating work that must be done from choices that are up to you.
