New Construction in Claremont
Most new construction in Claremont begins with a lot that already carries an existing house. The city grew in two distinct phases: an early-1900s college town core following incorporation on October 3, 1907, and a mid-century push northward through what had been citrus groves. That history left Claremont with Craftsman and bungalow houses near the Village and ranch houses further north, most of them small, compartmentalized, and sitting on foundations that were never meant to support a second story. When a structure is too far gone to remodel sensibly, a tear-down rebuild is often the cleaner path. Horizon Construction and Remodeling manages new construction in Claremont from the first lot review through design, engineering, permitting with the City of Claremont Building Division, demolition, and final inspection, all under one contract.

Our New Construction Process in Claremont
New construction in Claremont starts well before any floor plan is drawn. Because the city runs permits through the Building Division and applies design guidelines across its neighborhoods, we open every project with a zoning review, a boundary and topographic survey, and a soils report. Those documents tell us what the lot will support and what the foundation needs before a single elevation is sketched. From there, design moves forward with site plans, floor plans, and structural drawings developed alongside Title 24 energy documents, so the full plan set enters plan check complete and ready for review comments.
While plans are under review, we coordinate utility work, respond to city comments, and arrange the asbestos survey and air district notification required before any demolition. Claremont’s Preservation Ordinance adds a layer of review when a project touches a designated or eligible historic resource, which matters in the early-1900s blocks near the Village. Once permits issue, the build runs in sequence from foundation through framing, rough trades, insulation, and finishes, with one project manager on site for every inspection through final signoff.

Permits, Design Review, and Site Engineering in Claremont
All permits for new construction in Claremont run through the City of Claremont Building Division, and the review process typically touches more than one department. Planning checks the design against zoning standards, including setbacks, height limits, lot coverage, and floor area ratios. Building plan check covers the structural drawings and energy compliance documents. The fire department reviews sprinkler systems and site access, while public works handles grading, drainage, and any work in the public right of way such as a new driveway approach or street trenching. Because Claremont’s older neighborhoods, particularly around the Village, include properties that may qualify as historic resources, the city’s Preservation Ordinance can add a layer of review. Any project that touches a designated or eligible historic resource, or that sits in an area subject to citywide design guidelines, goes through a separate procedural review before building plan check moves forward.
Demolition of an existing structure requires its own permit and carries several prerequisites. Most building departments require gas and electric disconnection and sewer lateral capping before a demolition permit issues. The South Coast AQMD, which covers this part of the region, requires an asbestos survey and advance notification for most demolitions. Utilities serving the new house are then sized from scratch. Required fire sprinklers often call for a larger water meter and service line than the original house had, and a larger home with modern electrical loads and a solar array may need an upgraded service from the utility, which adds its own lead time to the schedule.
A geotechnical report comes before foundation design and drives several downstream decisions. The report identifies expansive clay, old fill, groundwater depth, and slope stability. In state-mapped liquefaction or landslide zones, a site-specific investigation is required. The structural engineer uses the soils data to size footings or design a post-tensioned slab or grade beams, and lays out shear walls, hold-downs, and beams to meet California seismic requirements. On sloped lots, which are common in areas like Claraboya and the foothills above the mid-century ranch neighborhoods, the same report informs the retaining wall design and grading plan. The soils engineer typically signs off on footing excavations before concrete is placed.
Energy compliance follows the 2025 Title 24 standards for permits filed on or after January 1, 2026, 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, the home is built to wildland-urban interface standards: a Class A roof assembly, ember-resistant vents, ignition-resistant exterior cladding, and multipane windows with tempered glass. Inspections cover each construction stage, from foundation forms and reinforcing steel through framing, rough-in trades, and insulation, all the way to the final sign-off.

Why Choose Horizon Remodeling For New Construction in Claremont
How We Handle New Construction in Claremont
Horizon Construction and Remodeling has been building in Southern California since 2009 as a licensed Class B general building contractor, bonded, and operating under a single contract that covers design, engineering coordination, permits, and construction. One project manager carries the job from the first sketch through final inspection, so the people who drew the plans are the same ones responding to plan check comments at the City of Claremont Building Division and building the house.
Claremont’s citywide design guidelines and Preservation Ordinance mean that even a new build on a lot near the Village or the mid-century neighborhoods to the north can face review requirements that affect setbacks, materials, and massing. We account for those considerations early, and California Title 24 energy requirements, CALGreen standards, and fire sprinkler obligations go into the design from the start rather than arriving as change orders later.
Before you sign anything, you can verify our license and bond status directly on the CSLB website. Call (714) 449-9035 to talk through your Claremont lot and find out what it can realistically support.

New Construction FAQ
Should I rebuild or remodel my house in Claremont?
The right choice depends on the condition of the house and what the lot allows. A full rebuild tends to make sense when the foundation has serious problems, when nearly every system needs replacing and most walls would move anyway, or when you want a second story the current structure cannot carry. In Claremont, where many homes near the Village carry historic or eligible status under the city’s Preservation Ordinance, that review process can also weigh into the decision. If the bones are sound and you mainly want a new layout and updated finishes, a whole-home remodel is usually simpler to permit through the City of Claremont Building Division. We walk the property with you and give you a straight comparison before you commit to either path.
What permits does a new home need?
Claremont’s permit process for new construction typically involves a demolition permit for the existing house, a building permit for the new structure, and separate grading, utility, and driveway permits through public works. Plans go to the City of Claremont Building Division, with planning, fire, and public works each reviewing their portion. Properties in a fire hazard severity zone face additional fire-code scrutiny. Because many Claremont lots sit within or near historically significant areas, design guidelines and preservation review procedures may also apply. We prepare and manage every submittal through approval.
How long does it take to build a new home?
Timelines for new construction in Claremont vary by project, and the design and permitting phase can take as long as the build itself. Plan check commonly runs several months, and projects touching a designated or eligible historic resource also move through the city’s Preservation Ordinance review process, which adds time. Construction of a custom home often runs close to a year, longer on sloped lots or where significant site work is involved. Weather, utility scheduling, and inspection availability all affect the pace, so we give you a realistic schedule after the feasibility review.
What drives the cost of building a new home?
Cost on a new construction project in Claremont is shaped first by size and complexity, particularly second stories, long spans, and lots of corners. Foundation type follows soil conditions and slope, and site work such as demolition, grading, retaining walls, and utility upgrades can differ significantly from one lot to the next. Finish level throughout the home also moves the number considerably. City impact fees and school fees on new square footage vary by jurisdiction and district, so after a feasibility review we break the budget into these categories so you can see clearly where your choices are.
Do new homes in California need solar and fire sprinklers?
Yes, new single-family homes in Claremont are subject to several overlapping state requirements that we build into the design from day one. The California Residential Code mandates automatic fire sprinklers, which affects water service sizing and how ceilings are laid out. Solar PV has been required 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 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, and starting from the ground up is the most efficient time to include an ADU. When we are already running water, sewer, and electrical service for the main house, we can size all of it for both units in a single coordinated effort and give each unit a separate entry and outdoor area on the site plan. State law permits ADUs on most single-family lots, though setbacks, height limits, and parking rules still apply and are reviewed by the City of Claremont Building Division. We can permit the ADU alongside the primary residence or handle it as a separate project, and we build guest houses as well.
