New Construction in Santa Ana
Most new construction in Santa Ana begins with a lot that already has a structure on it, because the city was built out over a long period and very little vacant residential land remains. The tracts around downtown were largely complete before World War II, and the outlying neighborhoods filled in through the 1950s and 1960s, leaving a housing stock of single-story Craftsman and Spanish Colonial Revival cottages alongside postwar ranch homes. When one of those houses is too small, carries a compromised foundation, or simply cannot support a second story without essentially rebuilding anyway, a tear-down and new build is often the more practical path. Horizon Construction and Remodeling manages new construction in Santa Ana from the initial lot review through design, engineering, permitting with the City of Santa Ana Building Safety Division, demolition, and final inspection, all under a single contract.

How We Approach New Construction in Santa Ana
New construction in Santa Ana begins well before anyone picks a floor plan. We open with a zoning review, a boundary and topographic survey, and a soils report, because the lot dictates what the foundation needs and what the City of Santa Ana Building Safety Division will expect to see. From there, design takes shape through site plans, floor plans, and elevations developed alongside you. Structural engineering and Title 24 energy documents are assembled with the drawings so the plan set enters plan check complete, not piecemeal.
If the existing structure sits in one of Santa Ana’s designated historic districts, such as Floral Park or French Park, alterations require a Certificate of Appropriateness reviewed against the Secretary of the Interior’s Standards, and we account for that review in the schedule. While plans are in review, we address comments, coordinate utility work, and arrange any required asbestos survey and air district notification before demolition begins. Once permits issue, the build runs in sequence from foundation through framing, rough trades, insulation, and finishes, with one project manager present for every inspection through final.

Getting a permit for new construction in Santa Ana means working through multiple agencies before a shovel touches the ground. Submittals go to the City of Santa Ana Building Safety Division, which sits inside the city’s Planning and Building Agency. From there, the project typically moves across several review desks at once. Planning checks setbacks, building height, lot coverage, and floor area against the zoning code. The building plan check team reviews structural calculations and energy documentation. The fire department evaluates sprinkler systems and site access, and public works addresses grading, drainage, driveway approaches, and any street trenching the utility connections require.
If the lot currently has a structure on it, demolition 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 is issued. The South Coast AQMD, which covers this region, requires an asbestos survey and advance notification for most demolitions. Once the site is clear, utilities get sized for the new house rather than the old one. A larger home with required fire sprinklers may need a bigger water meter and service line, and modern electrical loads combined with mandatory solar can mean a new service from the utility, which adds lead time to the schedule.
Santa Ana also includes several designated historic districts, among them Floral Park and French Park, where the older Craftsman and Spanish Colonial Revival housing stock has been protected under local historic designation. Any alteration or new construction within those boundaries requires a Certificate of Appropriateness, reviewed against the Secretary of the Interior’s Standards. That review adds a step that sits outside the standard building permit path and needs to be coordinated early so it does not delay the rest of the approval sequence.
On the technical side, a geotechnical report precedes foundation design. It identifies expansive clay, old fill, groundwater conditions, and slope stability, and in state-mapped liquefaction or landslide zones a site-specific investigation is required. The structural engineer uses that report to size footings or specify a post-tensioned slab, then designs the shear walls, hold-downs, and beams California’s seismic requirements demand. Energy compliance follows Title 24 standards, and solar PV is required on new single-family homes. A third-party HERS rater must field-verify certain energy measures. Inspections follow every stage, from foundation forms and reinforcing steel through framing, rough mechanical and electrical work, insulation, and the final walkthrough.

New Construction FAQ
Should I rebuild or remodel my house in Santa Ana?
Whether a rebuild makes more sense than a remodel depends on the condition of the house and what the lot allows. If the foundation has serious problems, if nearly every system needs replacing, if walls are moving anyway, or if zoning permits a larger or better-positioned structure, new construction is often the more practical path. Adding a second story the existing framing cannot carry is another common reason to start fresh. In Santa Ana’s older neighborhoods like Floral Park or French Park, any work on a designated historic property also requires a Certificate of Appropriateness reviewed against the Secretary of the Interior’s Standards, which can affect how far a remodel can realistically go. When the structure is sound and the goal is mainly a new layout and updated finishes, a whole-home remodel is typically simpler to permit through the City of Santa Ana Building Safety Division. We walk the property with you and give you a straightforward comparison before you decide.
What permits does a new home need?
New construction in Santa Ana typically requires a demolition permit for the structure coming down, a building permit for the new build, and separate grading, utility, and driveway permits through public works. The City of Santa Ana Building Safety Division, part of the Planning and Building Agency, reviews plans alongside planning, fire, and public works departments. Lots in a fire hazard severity zone receive additional fire-code review. We prepare all submittals and manage comments and resubmittals through each round of review.
How long does it take to build a new home?
Permitting and design can consume as much time as the build itself. Plan check with the City of Santa Ana Building Safety Division commonly runs several months, and that timeline stretches further when planning review or fire-zone considerations enter the picture. Construction of a custom home often takes close to a year, and larger footprints, difficult site conditions, or heavy grading work push that out further. Utility scheduling and inspection availability also shape the calendar, so we provide a realistic schedule tied to your specific lot after the feasibility review.
What drives the cost of building a new home?
New construction costs in Santa Ana are shaped first by size and complexity, with second stories, long spans, and irregular footprints all adding to the overall budget. Foundation design depends on soil conditions and how much the lot slopes, and site work, including demolition, grading, retaining walls, and utility upgrades, can differ considerably from one parcel to the next. Finish level throughout the home affects cost as well, and city impact fees and school fees on new square footage vary by jurisdiction and district. Once we complete a feasibility review, we break the budget into these categories so you can see exactly where your decisions matter most.
Do new homes in California need solar and fire sprinklers?
Yes, new single-family homes in Santa Ana 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 since the 2019 energy standards, and the 2025 Title 24 cycle raises the bar further 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 at the design stage, before anything goes to the City of Santa Ana Building Safety Division.
Can you build an ADU along with the new house?
Yes, and starting from the ground up is actually the simplest time to plan for an ADU. Water, sewer, and electrical service can be sized for both units during the same phase of work, and the site layout can give each unit a private entry and outdoor area from the start. State law permits ADUs on most single-family lots, though setbacks, height limits, and parking requirements still apply. On a Santa Ana lot, we submit the ADU through the City of Santa Ana Building Safety Division, either alongside the main house permit or as a separate application, and we build guest houses as well.
