New Construction in Montclair
In Montclair, most new construction starts with a lot that already has a house on it. The city grew out of the postwar tract boom on what had been citrus grove land, and the homes that filled neighborhoods along corridors like Holt Boulevard and Monte Vista Avenue tend to be compact single-story houses with attached garages and walled-off kitchens. Those houses can be worth remodeling, but when one sits on a tired foundation, runs too small, or cannot carry 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 Montclair from the first lot review through design, engineering, permits with the City of Montclair Building Division, demolition, and final inspection, all under one contract.

Our New Construction Process in Montclair
Pursuing new construction in Montclair means starting with the land itself before a single floor plan is sketched. Most lots here trace back to the postwar tract era, and because the building code and the age of the existing structure are the primary governing factors, we open with a zoning review, a boundary and topographic survey, and a soils report. Those findings shape the foundation design and tell us exactly what can be built. From there, site plans, floor plans, and elevations are developed alongside structural engineering and Title 24 energy documents, so the plan set that goes to the City of Montclair Building Division for plan check is complete from day one.
While plans are under review, we respond to any comments, coordinate utility work, and handle the asbestos survey and air district notification required before demolition. Once the City issues permits, the old structure comes down and the build moves in sequence: foundation, framing, rough plumbing, electrical, mechanical, fire sprinkler lines, insulation, and then exterior and interior finishes. One project manager oversees every phase and attends each inspection through final.

Building something new in Montclair means working through a permit process that touches several city departments before a single footing is poured. The City of Montclair Building Division is the central office, but a new house typically moves through more than one desk. Planning reviews setbacks, height limits, lot coverage, and floor area against zoning. Building plan check covers structural drawings and energy compliance documents. The fire department evaluates sprinkler systems and site access, and public works addresses grading, drainage, driveway approaches, and any trenching work that reaches into the street.
Demolition of an existing structure carries its own permit and its own sequence. Most building departments require the gas and electric service to be disconnected and the sewer lateral capped before that permit issues. Because so much of Montclair’s housing stock dates to the postwar tract boom of the late 1950s, materials like asbestos were common in original construction. The South Coast AQMD requires an asbestos survey and advance notification before most demolitions proceed, regardless of how straightforward the teardown looks on paper. No unusual local overlay applies in Montclair, so what governs is the state building code combined with the age and condition of whatever sits on the lot today.
Utilities get sized for the new house, not the one being replaced. Required fire sprinklers often mean a larger water meter and service line. A new home with modern electrical loads and a mandatory solar PV system may need a completely new service from the utility, which adds lead time to the schedule. The geotechnical report comes before 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 post-tensioned slabs or grade beams, and lay out shear walls and hold-downs for California seismic requirements.
Energy compliance follows the applicable 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 falls within a CAL FIRE Fire Hazard Severity Zone, wildland-urban interface standards apply: a Class A roof assembly, ember-resistant vents, ignition-resistant exterior materials, and multipane windows with tempered glass. Inspections run from foundation forms and reinforcing steel through framing, rough mechanical and electrical work, and insulation, all the way to the final sign-off before occupancy.

Why Choose Horizon Remodeling For New Construction in Montclair
Horizon Construction & Remodeling Inc. has been a licensed and bonded Class B general building contractor since 2009, and new home construction is the most complex work we take on. Montclair’s postwar tract housing stock means many lots in areas like North Montclair and along the Monte Vista Avenue corridor were built out decades ago on relatively compact footprints, so ground-up new construction here typically starts with a careful look at what the parcel can support under current zoning and building code.
We work design-build, which means design, engineering coordination, and construction all run under one contract with one project manager. Permits for new construction in Montclair go through the City of Montclair Building Division, and because no unusual local overlay applies, it is the California Building Code and your specific site conditions that govern. Having the same team manage plan check, respond to comments, and build the structure keeps that process from creating costly gaps.
Requirements like CALGreen compliance and Title 24 energy calculations are part of the design from the start, not items that surface later as change orders. Call (714) 449-9035 to tell us about your lot and we will give you a free estimate on what new construction there can realistically look like.

New Construction FAQ
Should I rebuild or remodel my house in Montclair?
Whether a rebuild makes sense depends on the house and the lot. On the compact postwar single-story homes that make up most of Montclair’s housing stock, a new construction project tends to be the right call 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 or better-placed house. If the structure is sound and you mostly want a new layout and finishes, a whole-home remodel is usually simpler to permit through the City of Montclair Building Division. We walk the property and give you a straight comparison before you commit.
What permits does a new home need?
The City of Montclair Building Division reviews the plans, with planning, fire, and public works typically signing off as well. On a tear-down project you can expect a demolition permit for the existing house, a building permit for the new one, and usually separate grading, utility, and driveway permits from public works. Because Montclair sits inland on what were once citrus grove tracts, no coastal development permit applies, and fire hazard severity zone overlays are not a standard factor here, so the building code and the age of the house are what govern the review. We prepare the submittals and manage every round of comments and resubmittals on your behalf.
How long does it take to build a new home?
Design and permitting can take as long as construction itself. Plan check with the City of Montclair Building Division commonly runs several months, and construction of a new home on a lot where postwar tract houses have stood since the 1950s often runs around a year, with larger footprints or heavy site work adding more time. Weather, utility company scheduling, and inspection availability all affect the pace, so we give you a schedule built around your specific lot after the feasibility review.
What drives the cost of building a new home?
The honest answer is that new construction costs depend on a short list of variables, and understanding them early keeps decisions clear. Structural complexity drives the largest share, particularly second stories, long spans, and plans with many corners. Foundation design follows soil conditions and slope, and site work such as demolition, grading, retaining walls, and utility upgrades can shift significantly from one Montclair lot to the next, especially on parcels that date to the postwar tract era when utility infrastructure was sized for smaller homes. Finish level throughout the structure affects cost at every stage. City impact fees and school fees tied to new square footage vary by jurisdiction and district, so we factor those in during feasibility. Once we have that picture, we break the budget into these categories so you can see exactly where your choices land.
Do new homes in California need solar and fire sprinklers?
Yes, new single-family homes in Montclair must meet several statewide requirements that shape the design before a single wall goes up. The California Residential Code mandates 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 extend those requirements for permits filed from January 1, 2026. CALGreen adds rules covering water use, construction waste recycling, indoor air quality, and EV charging readiness. We account for all of it from the start of design.
Can you build an ADU along with the new house?
Yes, and starting from the ground up is the most practical time to incorporate an ADU. Sizing water, sewer, and electrical service for both units at once is far more efficient than retrofitting later, and the site plan can give each unit a private entry and outdoor space from day one. State law allows ADUs on most single-family lots, though setbacks, height, and parking rules still apply and permits run through the City of Montclair Building Division. We can permit the ADU alongside the main house or as a separate project, and we build guest houses as well.
