New Construction in South Laguna
In South Laguna, new construction almost always begins with a lot that already holds an existing house. Most of the housing stock here dates to the mid-twentieth century, long before the 1987 annexation that folded the area into Laguna Beach, and the typical property is a modest cottage perched on a steep coastal or hillside lot that has been added onto repeatedly over the decades. When a structure is too small, carries a worn foundation, or cannot support a second story without rebuilding most of it anyway, a tear-down rebuild is often the cleaner solution. Horizon Construction and Remodeling manages new construction in South Laguna from the first lot review through design, engineering, permitting with the City of Laguna Beach Building Division, demolition, and final inspection, all under one contract.

Our New Construction Process in South Laguna
New construction in South Laguna starts with the land itself, because the steep coastal and hillside lots common here demand a zoning review, a topographic survey, and a soils report before a floor plan can mean anything. Design follows those findings, moving through site plan, floor plans, and elevations until the layout fits the way you actually live. Structural engineering and Title 24 energy documents are prepared alongside the drawings so the plan set enters the City of Laguna Beach Building Division complete, which matters in a coastal zone jurisdiction where plan check comments are common.
While plans are under review, we respond to comments, coordinate utility work, and handle the asbestos survey and air district notification required before any demolition. Once permits issue, the sequence runs in order: foundation, framing, rough plumbing, electrical, mechanical, and fire sprinkler lines, then insulation and finishes inside and out. One project manager carries the job from groundbreaking through every inspection to the final sign-off.

Because South Laguna was annexed into Laguna Beach in 1987, permits for new construction there go through the City of Laguna Beach Building Division rather than any separate South Laguna authority. That single permit destination covers several distinct review desks. Planning checks setbacks, height limits, lot coverage, and floor area against current zoning. Building plan check reviews structural calculations and energy documents. The fire department evaluates sprinkler systems and site access, and public works handles grading, drainage, street trenching, and new driveway approaches. Demolition of an existing structure requires its own separate permit, and most building departments will not issue it until gas and electric service is disconnected and the sewer lateral is capped. The South Coast AQMD also requires an asbestos survey and advance notification before most demolitions can proceed.
South Laguna sits inside the coastal zone governed by Laguna Beach’s certified Local Coastal Program, with the South Laguna Community Design and Landscape Guidelines adopted in 2022 forming part of that program. On a hillside lot in areas like Coast Royal or Camel Point, where much of the housing stock dates to the mid-twentieth century and lots are steep and modestly sized, those guidelines add a layer of design review on top of standard zoning. A geotechnical report is required before foundation design can begin. It documents expansive clay, old fill, groundwater depth, and slope stability. On sloped parcels the soils engineer typically must inspect footing excavations before any concrete is placed, and the same report drives both the retaining wall design and the overall grading plan.
The structural engineer uses the geotechnical findings to size footings, design post-tensioned slabs or grade beams where conditions call for them, and lay out shear walls, hold-downs, and beams sized for California seismic loads. Utilities get designed for the new house rather than carried over from the old one. Required fire sprinklers often mean a larger water meter and service line. A larger home with solar and modern electrical loads may need a new utility service, which adds its own lead time to the schedule.
Energy compliance follows Title 24 standards current at the time permits are filed, 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, the home must meet wildland-urban interface standards: a Class A roof assembly, ember-resistant vents, ignition-resistant exterior cladding, and multipane windows with tempered glass. Inspections are staged throughout construction, covering foundation forms and reinforcing steel, framing, rough mechanical and electrical work, insulation, and a final walkthrough before the certificate of occupancy is issued.

New construction in South Laguna carries permit and design requirements that go beyond a standard residential build. Because South Laguna was annexed into the City of Laguna Beach in 1987, permits run through the Laguna Beach Building Division rather than a separate local agency. The site also falls within the coastal zone under Laguna Beach’s certified Local Coastal Program, and the South Laguna Community Design and Landscape Guidelines adopted in 2022 are part of that program, meaning your plans need to satisfy those standards before they move forward. We coordinate the engineering, handle plan check comments, and keep the project on track through every review stage.
We work under a single contract covering design coordination, permitting, and construction, so nothing gets handed off between disconnected teams. California Title 24 energy requirements and CALGreen compliance are built into the drawings from the start. Call us at (714) 449-9035 to discuss what your South Laguna lot can support.

New Construction FAQ




Should I rebuild or remodel my house in South Laguna?
Whether a rebuild or a whole home remodel makes more sense depends on the condition of the house and what the lot allows. In South Laguna, where many homes in areas like Three Arch Bay and Coast Royal are mid-century cottages that have been added onto repeatedly on steep hillside lots, a rebuild often becomes the practical choice when the foundation has serious problems, when nearly every system needs replacement, or when zoning allows a larger or better-positioned structure the existing framing cannot support. If the bones are sound and the goal is a new layout with updated finishes, a remodel is typically simpler to permit through the City of Laguna Beach Building Division, which also administers coastal zone review under the Local Coastal Program. We walk the property with you and give a straight comparison before you commit to either path.
What permits does a new home need?
Pulling permits for new construction in South Laguna means working through the City of Laguna Beach Building Division, which has governed the area since the 1987 annexation. Expect a demolition permit for the existing structure, a building permit for the new one, and typically grading, utility, and driveway permits through public works, with planning, fire, and public works departments each signing off. Lots inside the coastal zone commonly require a coastal development permit, and fire hazard severity zone sites draw additional fire-code review. We handle the submittals, comments, and resubmittals throughout.
How long does it take to build a new home?
Custom home timelines in South Laguna vary considerably by lot and scope, so we give you a project schedule tied to your specific parcel after a feasibility review rather than quoting a number upfront. Design and permitting alone can run as long as the build itself, and plan check through the City of Laguna Beach Building Division frequently stretches several months, longer when a coastal permit under the Local Coastal Program or a hillside and fire-zone review is also required. Construction of a custom home commonly runs close to a year, and steep lots like those throughout Coast Royal or Camel Point, along with heavy site work, push that further. Weather, utility scheduling, and inspection availability all play a role.
What drives the cost of building a new home?
What drives the cost of new construction in South Laguna is size and complexity above everything else, particularly second stories, long spans, and plans with many corners. Foundation type is determined by soil conditions and slope, and on the steep hillside and coastal lots that are common throughout neighborhoods like Three Arch Bay and Camel Point, site work covering demolition, grading, retaining walls, and utility upgrades can differ dramatically from one parcel to the next. Coastal zone requirements under Laguna Beach’s Local Coastal Program add another layer of cost, as does the finish level you choose throughout the home. 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 each of these categories so you can clearly see where your decisions will have the most effect.
Do new homes in California need solar and fire sprinklers?
Yes, new construction in South Laguna must meet several state-level requirements that shape the project from day one. The California Residential Code requires automatic fire sprinklers in new one- and two-family homes, which affects both water service sizing and how ceilings are laid out. Solar PV has been mandatory on new single-family homes since the 2019 energy standards, and Title 24 requirements tighten 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. We account for all of it during design, well before anything goes to the City of Laguna Beach Building Division for review.
Can you build an ADU along with the new house?
Yes, a new build is the right time to add an ADU, because water, sewer, and electrical service can be sized for both units in a single effort and the site plan can give each unit a private entry and outdoor space. On the steep coastal and hillside lots common across South Laguna neighborhoods like Camel Point and Coast Royal, that kind of upfront planning matters. State law allows ADUs on most single-family lots, though setbacks, height, and parking rules still apply. We can permit the ADU alongside the main house or as its own project, and we build guest houses as well.
