New Construction in Midway City
Most new construction in Midway City begins with a lot that already carries an existing structure. Because the community’s street grid dates to 1922 and the bulk of its housing went up around 1956, a large share of properties hold small single-story postwar houses with compact enclosed kitchens, along with duplexes and mobile home units. Those homes can be worth remodeling, but when a foundation is tired, the footprint is too tight, or adding a second story would require rebuilding most of the structure anyway, a tear-down rebuild is often the cleaner path. Midway City is an unincorporated county community, so permits and inspections go through OC Development Services rather than a city building department, which affects the approval timeline and the standards that apply. Horizon Construction and Remodeling manages new construction in Midway City from the initial lot review through design, engineering, permitting, demolition, and final inspection, all under one contract.

Our New Construction Process in Midway City
New construction in Midway City moves through county channels rather than a city building department, because the community is unincorporated, which means permits and inspections go through OC Development Services and county standards apply throughout the build. We account for that from the first day. Before a floor plan takes shape, we work through a zoning review, a boundary and topographic survey, and a soils report, then carry structural engineering and Title 24 energy documents through the full plan set so nothing is missing when it enters county plan check.
Most lots here carry postwar single-story houses from the 1950s, and replacing one means coordinating an asbestos survey and air district notification before demolition begins. Once permits issue, the sequence runs foundation, framing, rough mechanical and utility lines, insulation, and then finishes, with one project manager present at every county inspection from groundbreaking through final sign-off.

Because Midway City is an unincorporated county community rather than an incorporated city, permits for new construction here go through OC Development Services rather than a local city hall. That distinction matters more than it might appear. The streets along the Bolsa Avenue corridor or the Hoover Street area can look and feel continuous with Westminster or Huntington Beach on either side, but Midway City is actually divided into four separate unincorporated county islands. County standards apply throughout, and county inspectors are the ones who show up, regardless of which city surrounds a given parcel.
A new house typically moves through more than one review desk at OC Development Services. Planning checks setbacks, height, lot coverage and floor area against zoning requirements. Building plan check reviews the structural documents and energy calculations. The fire department looks at sprinkler systems and site access. Public works covers grading, drainage, any trenching in the street and a new driveway approach. If an older structure is coming down first, demolition requires its own separate permit. Before that permit issues, most reviewing agencies want gas and electric service disconnected and the sewer lateral capped. The South Coast AQMD also requires an asbestos survey and advance notification prior to most demolitions.
Utility sizing follows the new house, not whatever was there before. Fire sprinkler requirements often drive the need for a larger water meter and service line. A bigger home with solar and modern electrical loads may require a new utility service entirely, and that carries its own lead time from the utility company. A geotechnical report comes before foundation design. It identifies expansive clay, old fill, groundwater conditions and slope stability. 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 for California seismic requirements. A 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. Where a 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 tempered-glass windows. Inspections cover every stage, from foundation forms and reinforcing steel through framing, rough-ins and insulation to the final sign-off.

Why Choose Horizon Remodeling For New Construction in Midway City
Horizon Construction and Remodeling is a licensed Class B general building contractor, bonded, and has been active since 2009. New construction is the most complex job a residential contractor takes on, and you can verify our license and bond directly through the CSLB before any contract is signed.
We work design-build, meaning design, engineering coordination, permits, and construction fall under one contract with one project manager. Because Midway City is an unincorporated county community, permits run through OC Development Services and county inspectors apply the standards, even where the streets look continuous with Westminster or Huntington Beach. We account for that from the start, so plan check comments do not catch the team off guard. CALGreen requirements and fire sprinkler provisions go into the drawings at the first pass rather than arriving as change orders later.
Most lots here trace back to the postwar street grid laid out decades ago, and the typical parcel was sized for a small single-story house. Understanding what a given lot can actually hold under county standards is the right first conversation to have. Call (714) 449-9035 and we will take a look at your Midway City lot and tell you what is realistic.

New Construction FAQ




Should I rebuild or remodel my house in Midway City?
Whether a rebuild or a whole home remodel makes more sense depends on the condition of the house and what the lot allows. A rebuild tends to be the right call when the foundation has serious problems, when nearly every system needs replacing and most walls would move anyway, when you want a second story the existing structure cannot carry, or when zoning allows a larger or better-placed house. In Midway City, because the community is an unincorporated county area, permits and inspections go through OC Development Services rather than a city building department, and county standards apply even where the streets run continuous with Westminster or Huntington Beach, so that process shapes the comparison too. If the structure is sound and the goal is mainly a new layout and updated finishes, a whole home remodel is usually simpler to permit. We walk the property with you and give you a straight comparison before you commit to anything.
What permits does a new home need?
Permitting a new build in Midway City runs through OC Development Services rather than a city hall, because the community is an unincorporated county area, which means county standards and county inspectors apply even where the streets flow without interruption into Westminster or Huntington Beach. Plan review typically involves planning, fire, and public works sign-off alongside the core building permit, and you should expect separate demolition, grading, utility, and driveway permits as well. Lots near the coast may require a coastal development permit, and any parcel in a fire hazard severity zone will face additional fire-code scrutiny. We prepare the submittals and manage the comments and resubmittals.
How long does it take to build a new home?
New construction timelines in Midway City vary more than most homeowners expect, and design and permitting can take as long as the build itself. Plan check commonly runs several months, and longer when planning review or other overlays are involved. Because Midway City is an unincorporated county community, permits go through OC Development Services rather than a city building department, and county standards and inspectors apply throughout. Construction of a custom home often runs around a year, more for larger homes or sites with heavy site work. Weather, utility scheduling, and inspection availability all affect the schedule, so we give you a timeline specific to your lot after the feasibility review.
What drives the cost of building a new home?
Budget for new construction in Midway City depends on several overlapping factors, and the biggest driver is usually the size and complexity of what you are building, particularly second stories, long spans, and irregular footprints. Foundation type is determined by soil conditions and slope, and site work, including demolition, grading, retaining walls, and utility upgrades, can shift considerably from one lot to the next on the postwar street grid laid out here in the 1920s. Finish level throughout the home adds another layer of cost variation. Because Midway City is an unincorporated county community, impact fees and school fees on new square footage run through Orange County rather than a city, so the numbers can differ from what neighbors in Westminster or Huntington Beach have paid. After 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 Midway City must meet several layered 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 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 updates apply to permits filed from January 1, 2026. CALGreen adds rules covering water use, construction waste recycling, indoor air quality, and EV charging readiness. Because Midway City is an unincorporated county community, all of this runs through OC Development Services rather than a city building department.
Can you build an ADU along with the new house?
Yes, building a new home is the ideal time to include an ADU or guest house on the same lot. Sizing water, sewer, and electrical service for both units at once is far more efficient than adding a unit later, and the site plan can give each unit a private entry and usable outdoor space. State law permits ADUs on most single-family lots, though setbacks, height limits, and parking requirements still apply. Because Midway City is an unincorporated county community, permits go through OC Development Services and county inspectors review the work, so we build that process into the schedule from the start. We can permit the ADU alongside the main house or handle it as a separate project, and we also build stand-alone guest houses.
