New Construction in East Irvine
Most new construction projects in East Irvine begin with a lot that already has a structure on it. Because residential development here grew from the 1970s onward under the Irvine Company master plan, the typical home is a stucco tract house or attached townhome on a slab foundation, and many of those older layouts simply cannot support a second story without rebuilding most of the structure anyway. In those cases, a tear-down rebuild is often the cleaner path forward. Horizon Construction and Remodeling manages new construction in East Irvine from the initial lot review through design, engineering, permits, demolition, and final inspection, all under one contract.

Our New Construction Process in East Irvine
How We Approach New Construction in East Irvine
New construction in East Irvine starts with the lot, not the floor plan. Because East Irvine falls within the City of Irvine, permits go through the City of Irvine Building and Safety Division, and we account for that process from day one. A zoning review, boundary and topographic survey, and soils report tell us what the site will support and what the foundation will need. Structural engineering and Title 24 energy documents are prepared alongside the drawings so the plan set enters plan check complete. If HOA architectural review applies, as it does across many of the master-planned villages here, we coordinate that review in parallel to avoid delays.
While plans are in review, we answer city comments, line up utility work, and handle the asbestos survey and air district notification required before demolition. Once permits issue, the build runs in order: foundation, framing, rough plumbing, electrical, mechanical and fire sprinkler lines, insulation, then exterior and interior finishes. One project manager runs the job from start to finish and is present for every inspection through final sign-off.

Permits for new construction in East Irvine run through the City of Irvine Building and Safety Division, because East Irvine is a district within the City of Irvine rather than a separate municipality. That means a single new house typically moves through several review desks before a permit issues. Planning checks the design against zoning requirements such as setbacks, height limits, lot coverage, and floor area. Building plan check reviews structural and energy documents, the fire department evaluates sprinkler systems and site access, and public works covers grading, drainage, street trenching, and any new driveway approach. If an older structure is coming down first, demolition needs its own permit, and most building departments require the gas and electric service to be disconnected and the sewer lateral capped before that permit is released. The regional air district, South Coast AQMD for most of this area, also requires an asbestos survey and advance notification before demolition begins. Two additional layers apply here specifically: Old Town Irvine carries the designation of California Historical Landmark No. 1004, and the villages surrounding it operate under homeowners association architectural review, so plans may need HOA approval alongside city review.
Utilities are sized for the new house, not for whatever stood there before. Required fire sprinklers often call for a larger water meter and service line. A bigger home with solar panels and modern electrical loads may also need a new service from the utility, and that upgrade carries its own lead time that needs to be built into the schedule early.
A geotechnical report comes before foundation design. It documents expansive clay, old fill, groundwater depth, and slope stability, and in state-mapped liquefaction or landslide zones a site-specific investigation is required. The structural engineer draws on that report to size footings, design a post-tensioned slab or grade beams, and lay out the shear walls, hold-downs, and beams that California seismic requirements demand. On sloped lots, the same report drives the retaining wall design and grading plan, and the soils engineer typically must sign off on footing excavations before any 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. Certain 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, ember-resistant vents, ignition-resistant exterior materials, and multipane windows with tempered glass. Inspections follow each phase of construction, from foundation forms and reinforcing steel through framing, rough mechanical and electrical, and insulation, all the way to the final sign-off.

That structure matters in East Irvine, where permits run through the City of Irvine Building and Safety Division and where villages like Northwood, West Irvine, and Portola Springs sit under homeowners association architectural review. Having one team handle plan check comments, HOA submittals, and field construction keeps the process from fragmenting. California energy and CALGreen requirements are factored into the design from the start, not added later as change orders.

New Construction FAQ
Should I rebuild or remodel my house in East Irvine?
The right path depends on your specific house and lot. A full rebuild tends to make sense when the foundation has serious problems, when nearly every system needs replacing and most walls are moving anyway, or when you want a second story the existing structure cannot support. In East Irvine, where many homes are stucco tract houses on slab foundations built under the Irvine Company master plan, zoning and HOA architectural review can also shape whether a rebuild or a whole-home remodel is the more practical route. If the structure is sound and the goal is mainly a new layout and updated finishes, a remodel is usually simpler to permit through the City of Irvine Building and Safety Division. We walk the property with you and give you a straight comparison before you commit to anything.
What permits does a new home need?
Replacing an existing house in East Irvine typically requires a demolition permit, a building permit for the new structure, and separate grading, utility, and driveway permits from public works. Because East Irvine is a district within the City of Irvine rather than a standalone city, all plans go through the City of Irvine Building and Safety Division, with planning, fire, and public works departments each signing off. Properties in a fire hazard severity zone receive additional fire-code review. We prepare every submittal and manage all comments and resubmittals on your behalf.
How long does it take to build a new home?
Realistic timelines vary by project, but design and permitting routinely take as long as the construction phase itself. In East Irvine, permits run through the City of Irvine Building and Safety Division, and plan check alone can span several months, with additional time added when HOA architectural review applies, as it does across many of the master-planned villages here. Custom home construction often runs close to a year, longer for larger homes or lots requiring heavy site work. Weather, utility scheduling, and inspection availability all shape the final schedule, so we work through the specifics with you after the feasibility review.
What drives the cost of building a new home?
Budget for new construction in East Irvine is driven first by size and complexity, particularly second stories, long roof spans, and plans with many corners. Because most homes here sit on slab foundations over master-planned tracts built from the 1970s onward, foundation decisions still depend on current soil conditions and any grading or retaining work your specific lot requires, and those costs can shift considerably from one parcel to the next. Demolition, utility upgrades, and site prep add their own line items. The finish level throughout the home, plus City of Irvine impact fees and school fees tied to new square footage, round out the major variables. If the work falls within a homeowners association village, architectural review requirements can influence materials and massing as well. Once we complete a feasibility review, we break the budget into each of these categories so you can see exactly where your decisions carry the most weight.
Do new homes in California need solar and fire sprinklers?
Yes, new single-family homes in East Irvine are subject to California’s automatic fire sprinkler requirement, which affects both water service sizing and how ceilings are laid out. Solar PV has been mandatory under the 2019 energy standards, and the 2025 Title 24 update adds further requirements for permits filed from January 1, 2026. CALGreen layers on top of that with rules covering water use, construction waste recycling, indoor air quality, and EV charging readiness. We account for all of it from the first design conversation.
Can you build an ADU along with the new house?
Yes, and new construction is often the simplest time to include an ADU or guest house. Sizing water, sewer, and electrical service for both units at once is far more efficient than returning later to expand capacity, and the site plan can position each unit with its own entry and outdoor space from the start. State law allows ADUs on most single-family lots, though setbacks, height, and parking rules still apply. In East Irvine, permits route through the City of Irvine Building and Safety Division, and projects within HOA-governed villages typically require architectural review alongside the standard building permit. We can permit the ADU together with the main house or handle it as a separate project.
