New Construction in Crestline
A tear-down rebuild is often the cleaner path when an existing cabin is too small, sits on a tired foundation, or cannot carry a second story without rebuilding most of it anyway. Crestline grew out of a weekend cabin community that took shape after the Lake Gregory dam was completed with Works Progress Administration funding in the late 1930s, and most lots today are narrow and sloped, with small one or two story structures that have had additions stacked uphill or downhill over the decades. Horizon Construction and Remodeling handles new construction in Crestline from the first lot review through design, engineering, permits, demolition, and the final inspection, all under one contract.

How We Approach New Construction in Crestline
New construction in Crestline starts with understanding the lot before anything else is decided. Because Crestline is unincorporated county territory, permits run through San Bernardino County Land Use Services, Building and Safety, and we prepare a complete plan set before submission so we are not chasing comments after the fact. That means a zoning review, boundary and topographic survey, and soils report come first, followed by site plans, floor plans, elevations, structural engineering, and Title 24 energy documents developed alongside the drawings. While plans are in review we answer county comments, coordinate utility work, and arrange the asbestos survey and air district notification required before any demolition begins.
Once permits issue, the old structure comes down and the build moves in sequence: foundation set to the Mountain Region frost line depth, framing designed for local snow load requirements, then rough plumbing, electrical, mechanical, and fire sprinkler lines, insulation, and exterior and interior finishes. One project manager runs the job from groundbreak through every county inspection to final sign-off.

Building a new house in Crestline means working through San Bernardino County Land Use Services, Building and Safety, not a city hall, because Crestline sits in unincorporated county territory. That distinction matters in practice. A new home typically moves through several review desks before a permit issues: planning checks setbacks, height, lot coverage, and floor area against zoning rules; building plan check reviews the structural drawings and energy documents; the fire department evaluates sprinkler systems and site access; and public works covers grading, drainage, any trenching near the street, and the driveway approach. If an older cabin is coming down first, demolition carries 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 South Coast AQMD also requires an asbestos survey and advance notification before most demolitions proceed.
Crestline’s Mountain Region design rules add requirements that do not apply in lower-elevation parts of Southern California. Footings must reach at least 18 inches below grade to get below the frost line. Any new or substantially altered roof must be engineered for snow load. Where a down-slope eave pitches steeper than 4:12, exits beneath it need protection from sliding snow and ice. These are not optional upgrades; they are baseline county requirements for building in this elevation zone, and the structural drawings need to address each one before plan check will sign off.
Before the foundation can be designed, a geotechnical report has to characterize the soil. On Crestline’s narrow, sloping lots, that report identifies expansive clay, old fill, groundwater depth, and slope stability. In state-mapped landslide zones, a site-specific investigation is required. The structural engineer uses those findings to size footings or specify a post-tensioned slab or grade beams, and to lay out shear walls, hold-downs, and beams for California seismic requirements. On a sloped lot the soils engineer typically has to observe and approve footing excavations before concrete is placed, and the same report drives both the retaining wall design and the grading plan.
Utilities get sized for the new house, not whatever the old cabin required. Fire sprinklers often call for a larger water meter and a bigger service line. A house with modern electrical loads and required solar PV may need a new utility service, which carries its own lead time independent of the building permit schedule. Energy compliance follows 2025 Title 24 standards for permits filed on or after January 1, 2026, and a third-party HERS rater must field-verify certain measures. If the lot falls within a CAL FIRE Fire Hazard Severity Zone, wildland-urban interface standards apply: a Class A roof assembly, ember-resistant vents, ignition-resistant exterior materials, and multipane windows with tempered glass. Inspections then follow each construction stage, from foundation forms and reinforcing steel through framing, rough-ins, and insulation to the final walkthrough and sign-off.

Why Choose Horizon Remodeling For New Construction in Crestline
Why Homeowners in Crestline Choose Horizon for New Construction
Horizon Construction and Remodeling has been building in Southern California since 2009, and we carry a Class B general building contractor license that stays current and active. We work design-build, meaning design coordination, engineering, permit submissions, and construction all fall under one contract with one project manager. That matters in Crestline because permits here run through San Bernardino County Land Use Services rather than a city building department, and plan check comments on mountain-region projects can move slowly. Having the same team that drew the plans answer those comments cuts delays that a split design-and-build arrangement typically creates.
Mountain Region design rules add real requirements to any new build on these slopes. Footings must reach eighteen inches below grade for frost protection, roofs must be engineered for snow load, and exits under down-slope eaves steeper than four-in-twelve need protection from sliding snow and ice. We work those details into the drawings from the start, so they do not appear later as change orders.
CALGreen and Title 24 energy requirements are also part of the first sketch, not an afterthought. Specialty trade work, including electrical, plumbing, and any required fire sprinkler systems, is performed by appropriately licensed subcontractors we coordinate directly.

New Construction FAQ
Should I rebuild or remodel my house in Crestline?
Whether a full rebuild or a whole home remodel makes more sense depends on the condition of the house and what the lot allows. In Crestline, where most homes started as weekend cabins built after the Lake Gregory dam was completed in the late 1930s, we often find foundations with serious issues, nearly every system due for replacement, and walls that would move regardless. When that is the case, or when the current structure cannot carry a second story and zoning allows a larger footprint, new construction is usually the cleaner path. If the framing is still solid and you mainly want a different layout and updated finishes, a whole home remodel typically permits more simply. San Bernardino County Land Use Services handles building permits for unincorporated Crestline, and Mountain Region rules add requirements like an 18 inch frost line depth and snow load design on any new or altered roof. We walk the property and give you a straight comparison before you decide anything.
What permits does a new home need?
Building new in Crestline means navigating several permits at once: demolition for the existing structure, building for the new one, and typically grading, utility, and driveway permits through public works as well. Because Crestline is unincorporated county territory, plans go through San Bernardino County Land Use Services, Building and Safety, with planning, fire, and public works each signing off. Lots in a fire hazard severity zone receive additional fire-code review. We prepare the submittals and manage all comments and resubmittals on your behalf.
How long does it take to build a new home?
Design and permitting can take as long as the build itself, and in Crestline that reality hits early. San Bernardino County Land Use Services handles plan check for this unincorporated mountain community, and review cycles commonly run several months, longer when hillside grading, fire-zone conditions, or Mountain Region structural requirements such as snow load and frost line depth enter the picture. Construction of a custom home typically runs around a year, more for larger plans, steep terrain, or substantial site work. Weather, utility scheduling, and inspection availability all shape the timeline, so we give you a project schedule tied to your specific lot after the feasibility review.
What drives the cost of building a new home?
Budget for new construction in Crestline is driven first by size and structural complexity, particularly second stories, long spans, and irregular floor plans. Because most lots here are narrow and steeply pitched, site work such as grading, retaining walls, and utility upgrades can shift significantly from one parcel to the next, and foundation design depends on both soil conditions and slope. San Bernardino County Land Use Services handles permitting for this unincorporated area, and Mountain Region rules add requirements for frost-depth footings, snow-load roof design, and snow and ice protection at certain exits. Fire-zone material requirements, finish level choices, and county or school district fees on new square footage round out the major cost categories, and once we complete a feasibility review we break the estimate into those areas 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 Crestline require automatic fire sprinklers under the California Residential Code, which affects how water service is sized and how ceilings are laid out. Solar PV has been mandatory since the 2019 energy standards, and permits filed from January 1, 2026 fall under updated 2025 Title 24 requirements. CALGreen adds rules for water use, construction waste recycling, indoor air quality, and EV charging readiness. Because Crestline is unincorporated county territory, all of this runs through San Bernardino County Building and Safety, and we design to every requirement from the first drawing.
Can you build an ADU along with the new house?
Yes, a new construction project is the easiest point at which to add an ADU, because water, sewer, and electrical service can be sized for both units in a single scope of work and the site plan can give each unit a separate entry and outdoor space from the start. State law allows ADUs on most single-family lots, though setbacks, height, and parking rules still apply. On the sloping lots common throughout areas like Valley of Enchantment and Cedarpines Park, that site planning matters more than most people expect. Permits for both the main house and the ADU go through San Bernardino County Land Use Services, Building and Safety, since Crestline is unincorporated county territory, and Mountain Region requirements covering frost line depth, snow load, and ice protection at roof exits factor into the structural design for any new build here. We can permit the ADU alongside the main house or carry it as a separate project, and we build guest houses as well.
