New Construction in West Covina
For most new construction projects in West Covina, the starting point is a lot that already has a house sitting on it. The city’s housing stock is largely a product of the postwar boom, when West Covina grew more than tenfold in a single decade following its 1923 incorporation, leaving the area filled with single-story tract homes on suburban lots. Those houses can be solid candidates for remodeling, but when a home is too cramped, carries foundation problems, or simply cannot support a second story without rebuilding most of the structure anyway, a tear-down and rebuild is often the more practical choice. Horizon Construction and Remodeling manages new construction in West Covina from the initial lot review through design, engineering, City of West Covina permitting, demolition, and final inspection, all under a single contract.

Our New Construction Process in West Covina
New construction in West Covina begins before a single drawing is made, because the lot itself sets the rules. We open with a zoning review, a boundary and topographic survey, and a soils report, so the foundation design is grounded in what the ground actually requires. From there, the design phase produces a site plan, floor plans, and elevations, worked through with you until the layout fits how you actually live. Structural engineering and Title 24 energy documents are prepared alongside those drawings, so the plan set enters the City of West Covina building department complete and ready for review.
While plans are in review, we respond to any comments, coordinate utility work, and arrange the asbestos survey and air district notification required before demolition can begin. Many West Covina homes date to the postwar tract-building era, so that survey step is rarely skipped. Once permits issue, the sequence runs in order: foundation, framing, rough plumbing, electrical, mechanical, insulation, and finishes. One project manager carries the job from groundbreaking through every inspection to the final sign-off.

Pulling permits for new construction in West Covina means working through the City of West Covina’s building department, which issues all permits for work inside city limits. Because no unusual local overlay applies here, the governing factors are the California Building Code and the specifics of your lot and existing conditions. That is straightforward in one sense, but a full new-home build still moves through several review desks before a permit issues. Planning checks setbacks, height, lot coverage and floor area against zoning requirements. Building plan check reviews structural drawings and energy compliance documents. The fire department evaluates sprinkler systems and site access, and public works handles grading, drainage, any street trenching and a new driveway approach.
If an older structure is coming down first, demolition carries its own permit and its own sequence. Most building departments require the gas and electric services to be disconnected and the sewer lateral capped before that permit issues. The South Coast AQMD also requires an asbestos survey and advance notification for most demolitions. West Covina’s housing stock is predominantly postwar construction from the 1950s, the decade when the city grew more than tenfold and tract homes went up across suburban lots throughout the area. Homes from that era can contain asbestos in flooring, insulation and joint compound, so the survey step is rarely just a formality on a teardown here.
Once demolition is cleared, utility sizing begins for the new house rather than the old one. Required fire sprinklers often mean a larger water meter and service line. A bigger home with modern electrical loads and mandatory solar PV may also need an upgraded service from the utility, and that coordination carries its own lead time outside the building department’s control.
Foundation design follows a geotechnical report, which identifies expansive clay, old fill, groundwater and slope stability concerns. In state-mapped liquefaction or landslide zones a site-specific investigation is required. The structural engineer uses those findings to size footings or design a post-tensioned slab, then lays out shear walls, hold-downs and beams to meet California’s seismic requirements. Energy compliance follows the applicable Title 24 standards, and new single-family homes must include solar PV. If the lot falls within a CAL FIRE Fire Hazard Severity Zone, wildland-urban interface standards apply, covering roof class, ember-resistant vents, ignition-resistant exterior materials and tempered multipane windows. Inspections follow each construction phase, from foundation forms and reinforcing steel through framing, rough-ins and insulation to the final sign-off.

Why Choose Horizon Remodeling For New Construction in West Covina
Horizon Construction & Remodeling Inc. has been building in Southern California since 2009, and new construction is among the most involved work we take on. We hold a Class B general building contractor license and are bonded, which you can confirm directly through the CSLB before you commit to anything.
We work design-build, meaning design, engineering coordination, permits, and construction all move under one contract with one project manager. That structure matters in West Covina because permits go through the City of West Covina’s building department, and having the same team answer plan check comments that drew the plans keeps things moving. CALGreen compliance, fire sprinkler requirements, and Title 24 energy standards go into the design from the start, not as surprises mid-project.
West Covina’s housing stock is largely postwar tract construction from the 1950s building boom, so many lots carry older infrastructure and site conditions that a new build has to account for from the ground up. The age of the existing house and the current building code are what govern the scope. Call (714) 449-9035 and we will take a look at your West Covina lot and tell you what it can realistically support.

New Construction FAQ
Should I rebuild or remodel my house in West Covina?
Whether a rebuild makes sense depends on the condition of your lot and the house sitting on it. In West Covina, where most homes are postwar single-story tract houses built in the 1950s, a new construction project often becomes the stronger choice when the foundation has serious issues, when nearly every system needs replacement and most walls would move anyway, or when zoning allows a larger or better-positioned house than the existing structure supports. If the bones are solid and the changes are mostly layout and finishes, a whole-home remodel is usually simpler to permit through the City of West Covina. We walk the property with you and give a straight comparison before you decide anything.
What permits does a new home need?
Tearing down an existing house and building new in West Covina typically requires a demolition permit, a building permit for the new structure, and grading, utility, and driveway permits through public works. The City of West Covina issues building permits for work inside city limits, and planning, fire, and public works departments usually all sign off during review. Because no unusual local overlay applies here, the building code and the age of the existing house are the main factors that shape the submittal. We prepare the documents and manage every round of comments and resubmittals.
How long does it take to build a new home?
New construction in West Covina moves at a pace shaped by the City of West Covina permit process, your lot conditions, and the scope of the build. Plan check alone commonly runs several months, so design and permitting can take as long as construction itself. A custom home often runs around a year to build, more for larger footprints or sites requiring heavy grading. Weather, utility scheduling, and inspection availability all factor in, so we put a realistic schedule together after the feasibility review.
What drives the cost of building a new home?
What drives new construction costs in West Covina comes down to size, complexity, and what the site demands before framing even begins. Second stories, long spans, and irregular footprints add to structural requirements, and foundation design depends on soil conditions and slope, which can differ from one lot to the next across neighborhoods like South Hills or Cortez Park. Site work, including demolition, grading, retaining walls, and utility upgrades, varies widely. Finish level throughout the home, plus City of West Covina impact fees and applicable school fees on new square footage, shape the final number. Once feasibility is confirmed, we break the budget into these categories so you can see exactly where your decisions matter.
Do new homes in California need solar and fire sprinklers?
Yes, new homes in West Covina must meet current California building requirements, and we design to all of them from the start. The California Residential Code requires automatic fire sprinklers in new one- and two-family homes, which affects both water service size and ceiling layout. Solar PV has been required on new single-family homes since the 2019 energy standards, and the 2025 Title 24 standards build on that for permits filed from January 1, 2026. CALGreen adds rules covering water use, construction waste recycling, indoor air quality, and EV charging readiness.
Can you build an ADU along with the new house?
Yes, an ADU can absolutely be included with a new construction project, and building both at the same time is the most practical approach. Utility connections for water, sewer, and electrical can be sized to serve both units from the start, and the site plan can position each unit with its own entry and outdoor space. This is worth considering in West Covina, where many postwar lots were laid out with room to the rear. State law permits ADUs on most single-family lots, though setbacks, height limits, and parking requirements still apply. Horizon can permit the ADU alongside the main house or handle it as a separate permit, and we build guest houses as well.
