New Construction in San Fernando
Most new construction in San Fernando begins with a lot that already carries a structure on it. The city grew outward from a townsite incorporated in August 1911, and housing filled in steadily across the twentieth century as the valley urbanized around it, leaving a dense grid of small single-family and two-family homes where narrow lot widths can limit what a remodel can realistically accomplish. When a house sits on a tired foundation, runs too small, or cannot support a second story without rebuilding most of it anyway, a tear-down rebuild is often the cleaner path. Horizon Construction and Remodeling manages new construction in San Fernando from the first lot review through design, engineering, permits with the City of San Fernando Building and Safety Division, demolition, and final inspection, all under one contract.

How We Approach New Construction in San Fernando
New construction in San Fernando starts with understanding what the lot will actually allow, because on the dense grid that defines most of this city, lot width shapes every decision before a floor plan is ever drawn. We open with a zoning review, a boundary and topographic survey, and a soils report, then develop the site plan, floor plans, and elevations alongside structural engineering and Title 24 energy documents so the package that goes to the City of San Fernando Building and Safety Division is complete from day one. If demolition is involved, the asbestos survey and air district notification happen during plan review, not after.
Once permits issue, the build runs in a defined order: foundation, framing, rough plumbing, electrical, mechanical, and fire sprinkler lines, then insulation, exterior cladding, and interior finishes. Because many homes here date back to mid-twentieth-century construction, the age of the existing structure and the current building code are what govern scope and materials. One project manager stays on from start to final inspection.

Permits, Engineering, and Code Compliance for New Construction in San Fernando
San Fernando’s housing stock grew in layers across the twentieth century, filling a tight grid that incorporated as a city in August 1911. That history matters when you pull a permit today, because the building code and the age of any existing structure on the lot are the primary factors that govern the review. No unusual local overlay applies here, which keeps the process straightforward, but it does not make it short. Permits go through the City of San Fernando Building and Safety Division, and on a new house the application touches more than one desk. Planning reviews setbacks, height, lot coverage, and floor area against zoning. The building plan check covers structural and energy documents. The fire department examines sprinkler requirements and site access. Public works handles grading, drainage, street trenching, and a new driveway approach.
If demolition is part of the scope, it requires its own permit. Most building departments want gas and electric service disconnected and the sewer lateral capped before that permit issues. The South Coast AQMD requires an asbestos survey and advance notification ahead of most demolitions in this region. Once the site is clear, utilities get sized for the new house, not the old one. Required fire sprinklers frequently mean a larger water meter and service line. A bigger house carrying solar panels and modern electrical loads may also need a new utility service, and coordinating that connection adds lead time to the schedule.
A geotechnical report precedes foundation design. It identifies expansive clay, old fill, groundwater conditions, and slope stability. In state-mapped liquefaction or landslide zones, a site-specific investigation is required. The structural engineer uses those findings to size footings, design a post-tensioned slab or grade beams, and lay out shear walls, hold-downs, and beams to meet California seismic standards. On a sloped lot the same report drives retaining wall design and the grading plan, and the soils engineer typically signs off on footing excavations before concrete is placed.
Energy compliance follows Title 24 standards, and new single-family homes must include solar PV. Some measures require field verification by a third-party HERS rater. If the lot sits within a CAL FIRE Fire Hazard Severity Zone, wildland-urban interface standards apply: a Class A roof, ember-resistant vents, ignition-resistant exterior materials, and multipane windows with tempered glass. Inspections mark each stage of the build, from foundation forms and reinforcing steel through framing, rough-ins, and insulation, all the way to final sign-off.

Why Choose Horizon Remodeling For New Construction in San Fernando
Horizon Construction and Remodeling has been building across Southern California since 2009 as a licensed Class B general building contractor, and we are bonded. New construction is the most demanding work a residential contractor takes on, and we encourage every homeowner to verify our credentials directly through the CSLB before signing a contract.
We work design-build, which means design, engineering coordination, permits, and construction all move under one contract with one project manager. In San Fernando, permits go through the City of San Fernando Building and Safety Division, and because no unusual local overlay applies, the governing factors are the California building code and the age of the property. We account for CALGreen requirements, fire sprinkler systems, and solar provisions from the earliest design sketch, so those items do not arrive late as change orders.
San Fernando’s dense grid of small lots, many of them sized during the town’s early twentieth-century buildout, means a plan drawn for a wide suburban lot rarely fits here without adjustment. We look at your specific parcel and work within what it can realistically hold. Call us at (714) 449-9035 to talk through your lot and get a free estimate.

New Construction FAQ
Should I rebuild or remodel my house in San Fernando?
The right choice depends on the condition of your house and what your lot allows. A full rebuild tends to make sense when the foundation has serious problems, when you would be replacing nearly every system and moving most walls anyway, when you want a second story the existing structure cannot carry, or when zoning allows a larger footprint than what stands today. On the dense grid of San Fernando, where lot width can limit how far a floor plan can grow sideways, rebuilding sometimes opens options a remodel cannot. If the structure is sound and the changes are mostly layout and finishes, a whole-home remodel is usually simpler to permit through the City of San Fernando Building and Safety Division. We walk the property with you and give a straight comparison before you commit to anything.
What permits does a new home need?
Permits for new construction in San Fernando run through the City of San Fernando Building and Safety Division, which coordinates review with planning, fire, and public works before anything gets approved. A typical project requires a demolition permit for the structure coming down, a building permit for the new one, and grading, utility, and driveway permits from public works as well. Because no unusual local overlay applies here, the building code and the age of the existing house are what drive the requirements. We prepare the submittals and manage every round of comments and resubmittals.
How long does it take to build a new home?
Design and permitting together can take as long as the build itself. Plan check with the City of San Fernando Building and Safety Division commonly runs several months, and construction of a new custom home often runs close to a year, longer for larger footprints or sites requiring heavy prep work. On the dense grid that defines most of San Fernando, lot width and existing utility connections shape the schedule as much as anything else. Weather, inspection availability, and utility company coordination all shift timelines, so we work out a realistic schedule for your specific lot after the feasibility review.
What drives the cost of building a new home?
What drives the cost of new construction in San Fernando is scope and site conditions more than anything else. A second story, long structural spans, or an irregular footprint all add to the budget, and foundation decisions depend on the soils beneath your specific lot. Because the city incorporated in 1911 and housing filled in gradually across the twentieth century, site work, including demolition, grading, retaining walls, and utility upgrades, can vary considerably from one block to the next. Finish level throughout the home matters too. The City of San Fernando Building and Safety Division sets the permit and fee requirements, and school fees on new square footage depend on the district. Once we assess feasibility, we break the budget into these categories so you know exactly where your decisions carry the most weight.
Do new homes in California need solar and fire sprinklers?
Yes, new one- and two-family homes in San Fernando must include automatic fire sprinklers under the California Residential Code, which affects both water service sizing and how ceilings are laid out. Solar PV has been required on new single-family homes since the 2019 energy standards, and the 2025 Title 24 update raises the bar further for permits filed on or after January 1, 2026. CALGreen layers on top of that with requirements covering water use, construction waste recycling, indoor air quality, and EV charging readiness. On the dense grid streets around corridors like Maclay Avenue, where lots run narrow and the City of San Fernando Building and Safety Division reviews every permit, meeting all of these standards from the first drawing session is the only practical approach, and that is exactly how we work.
Can you build an ADU along with the new house?
Building an ADU alongside new construction in San Fernando is straightforward because water, sewer, and electrical service can be sized for both units at once, and the site plan can give each unit a separate entry and outdoor space from the start. On the dense residential grid that fills much of the city, state law allows ADUs on most single-family lots, though setbacks, height, and parking rules still apply. The City of San Fernando Building and Safety Division handles permitting, and we can include the ADU in the main house permit or run it as its own project. We also build guest houses.
