New Construction in Placentia
A tear-down rebuild is often the cleaner path when an existing home is too small, sits on a tired foundation, or cannot carry a second story without rebuilding most of it anyway. Placentia was largely built out during the 1960s and 1970s, when the population jumped from roughly 5,000 to nearly 25,000 in a single decade, leaving the city with a stock of flat-lot tract houses that can be good candidates for that approach. Horizon Construction and Remodeling manages new construction in Placentia from the initial lot review through design, engineering, permits with the City of Placentia Development Services Department, demolition, and final inspection, all under one contract.

Our New Construction Process in Placentia
New construction in Placentia typically starts well before anyone draws a floor plan. We open with a zoning review, a boundary and topographic survey, and a soils report, because those documents tell us what the site will support and what the foundation will require. Placentia’s Development Services Department handles plan check, and if your property falls within the Old Town Placentia Revitalization Plan area, it carries its own adopted development standards, so we confirm which rules apply before design begins. Structural engineering and Title 24 energy documents are prepared alongside the drawings so the plan set enters review complete.
While plans are under review, we respond to any comments, coordinate utility work, and arrange the asbestos survey and air district notification required before demolition. Once permits issue, the old structure comes down and the build follows a set sequence: foundation, framing, rough plumbing, electrical, mechanical and fire sprinkler lines, insulation, then exterior and interior finishes. One project manager stays on the job from groundbreaking through every inspection to final sign-off.

Building a new home in Placentia means working through a multi-step review process before a single footing is poured. Permits go through the City of Placentia Development Services Department, and for new construction that typically means more than one review desk. Planning checks your design against zoning requirements, including setbacks, height limits, and lot coverage. Building plan check reviews the structural drawings and energy compliance documents. The fire department looks at sprinkler systems and site access, and public works covers grading, drainage, and any new driveway approach. If you are demolishing an existing structure first, that work requires its own separate permit, and most building departments want gas and electric services disconnected and the sewer lateral capped before that permit is issued. The South Coast AQMD also requires an asbestos survey and advance notification before most demolitions proceed.
One detail that matters depending on where your lot sits: properties within the Old Town Placentia Revitalization Plan area are subject to their own adopted development standards, which run separately from the standard building and zoning code that applies everywhere else in the city. Most of Placentia’s housing stock was built out during the 1960s and 1970s, when the city grew rapidly, so many of these sites carry older infrastructure. Utilities serving a new house get sized for the new structure, not whatever was there before. Required fire sprinklers often call for a larger water meter and service line, and a house with modern electrical loads and mandatory solar may need a new utility service entirely, which adds its own lead time to the schedule.
A geotechnical report comes before foundation design. It identifies expansive clay, old fill, and groundwater conditions, and in state-mapped liquefaction 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 to meet California seismic requirements. The soils engineer typically signs off on footing excavations before any concrete is placed.
Energy compliance follows current Title 24 standards, and new single-family homes are required to include solar PV. Some measures require field verification by a third-party HERS rater. If the lot falls within a designated Fire Hazard Severity Zone, wildland-urban interface construction standards apply, covering roof class, ember-resistant vents, exterior materials, and window glazing. Inspections are required at each stage, from foundation forms and rebar through framing, rough-in trades, insulation, and the final walkthrough with the building department.

Why Choose Horizon Remodeling For New Construction in Placentia
Horizon Construction and Remodeling has been operating as a licensed and bonded Class B general building contractor since 2009, and new home construction is the most complex project we take on. Before you sign any contract, you can verify our license and bond status directly through the CSLB public database. We bring design, engineering coordination, permitting, and construction together under a single contract managed by one point of contact throughout the job.
Because most of Placentia’s housing stock dates to the 1960s and 1970s tract-home boom, vacant lots suitable for new construction are relatively uncommon inside the established neighborhoods. When a buildable parcel does come available, permits run through the City of Placentia Development Services Department. Properties within the Old Town Placentia area are also subject to that district’s adopted development standards, which shape what can be built there and how the design review process works.
We coordinate California Title 24 energy requirements, CALGreen compliance, and fire-protection needs from the earliest design stage so those items are never a late surprise. Specialty trade work is performed by appropriately licensed subcontractors we manage directly. Call (714) 449-9035 to talk through what your Placentia lot can support and to request a free estimate.

New Construction FAQ
Should I rebuild or remodel my house in Placentia?
Whether a rebuild makes sense depends on the condition of the house and what the lot allows. On the flat suburban lots that are typical throughout Placentia, where most homes went up during the tract-building boom of the 1960s and 1970s, the decision usually comes down to the foundation, the systems, and the walls. A new build tends to make more 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 or better-placed house. If the structure is sound and the goal is mainly a new layout and updated finishes, a whole-home remodel is generally simpler to permit through the City of Placentia Development Services Department. 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?
New construction in Placentia requires several permits working in parallel: a demolition permit for the existing structure, a building permit for the new one, and typically grading, utility, and driveway permits through public works. The City of Placentia Development Services Department reviews plans, with planning, fire, and public works each signing off. Properties within the Old Town Placentia area fall under that district’s adopted development standards, which adds a layer to the review process. We handle all submittals, agency comments, and resubmittals.
How long does it take to build a new home?
Custom new construction in Placentia moves on its own timeline, and the design and permitting phase can run as long as the build itself. Plan check commonly takes several months, and projects that trigger additional planning review stretch longer. Construction of a custom home often runs around a year, with larger homes adding more time. Because most Placentia lots are flat postwar parcels rather than hillside sites, heavy grading rarely slows things down, but utility scheduling and inspection availability still affect the calendar. We give you a schedule tied to your specific lot after the feasibility review.
What drives the cost of building a new home?
Budget for a new construction project in Placentia breaks down into a handful of categories, and complexity drives cost more than anything else. Second stories, long spans, and irregular floor plans add to the structural scope, while foundation type depends on soil conditions at the specific lot. Because most of the city was built out during the 1960s and 1970s on flat suburban parcels, site work is often straightforward, though demolition, utility upgrades, and any retaining needs still vary. City impact fees and school fees on new square footage are set by the City of Placentia and the applicable district, so we account for those during feasibility. Properties within the Old Town Placentia area may also fall under that district’s adopted development standards, which can affect design decisions. Finish level throughout the home is another significant variable. We walk through each of these categories with you early so you can see clearly where your decisions carry the most weight.
Do new homes in California need solar and fire sprinklers?
Yes, new homes in Placentia must meet several overlapping state 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 sizing and ceiling layout. Solar PV has been mandatory on new single-family homes since the 2019 energy standards, and the 2025 Title 24 standards add further requirements for permits filed from January 1, 2026. CALGreen also covers water use, construction waste recycling, indoor air quality, and EV charging readiness.
Can you build an ADU along with the new house?
Yes, adding an ADU during new construction is straightforward. Sizing water, sewer, and electrical service for two units at the same time is far simpler than retrofitting later, and the site plan can give each unit a private entry and outdoor area from the start. Most single-family lots in Placentia’s postwar tracts qualify under state law, though setbacks, height limits, and parking rules still apply. Permits run through the City of Placentia Development Services Department, and properties in the Old Town area fall under its own adopted development standards.
