HomeSense Construction & Remodeling delivers new construction in Chatsworth, CA — from ground-up custom homes and teardown-rebuilds to accessory dwelling units and SB 9 lot-split projects. As a licensed general contractor (CA Lic #1125001) building across the San Fernando Valley since 2011, we handle architecture, structural engineering, LADBS permitting, and every trade under one roof, so your Chatsworth home is built on schedule, on budget, and to 2026 California code.

Ground-Up Home Building in Chatsworth

Chatsworth sits at the northwest edge of the San Fernando Valley, where larger lots, established ranch-style homes, and the Santa Susana foothills create some of the Valley’s best opportunities for building new. Many of our Chatsworth clients buy an older single-story home on a generous lot and rebuild a modern two-story residence, add a detached ADU for family or rental income, or develop two units on one parcel under California’s SB 9. Because our headquarters is minutes away in West Hills, we know the local lots, soil conditions, and the LADBS plan-check process that governs this part of the Valley.

We build single-family custom homes, spec homes, teardown-and-rebuild projects, and second dwellings — and we manage the entire project from the first site visit to your final certificate of occupancy.

What Our New-Construction Service Includes

Site & feasibility review — lot survey, soils and geotechnical coordination, setbacks, and zoning check.
Architectural design & structural engineering — full plans built around how you live and Chatsworth’s terrain.
Title 24 2026 energy compliance — cool roofing, high-performance insulation, efficient HVAC, and solar-ready wiring.
LADBS permits & plan check — we prepare, submit, and shepherd your permit package through the city.
Complete build — foundation, framing, roofing, plumbing, electrical, HVAC, drywall, and finish carpentry.
Final inspections & closeout — sign-offs, certificate of occupancy, and a walkthrough of your finished home.

Chatsworth New-Construction Costs in 2026

In 2026, ground-up home building in the San Fernando Valley generally runs $350–$450 per square foot for builder-grade or spec work, $450–$650 per square foot for mid-range custom homes, and $700–$1,000+ per square foot for high-end or hillside builds in the Santa Susana foothills. A typical 2,500-square-foot custom home in Chatsworth commonly lands between $1.1M and $1.8M for construction, with land purchased separately. Budgets should also plan for soft costs — architecture, engineering, and permits — plus a 5–10% contingency for site surprises. Hillside lots add soils reports, retaining walls, grading, and specialized foundations. For a full breakdown by project type, see our remodeling & construction cost guides, and we always provide a detailed, fixed written estimate before any work begins.

Permits, Zoning & 2026 California Codes

Every Chatsworth build we manage is permitted through LADBS and engineered to current California code. That includes the 2026 Title 24 energy standards (cool-roof and building-envelope requirements that also lower your utility bills), seismic and soils requirements, and the newest housing laws. Under SB 9, many single-family lots in Chatsworth can be split or developed with two units, and updated 2026 ADU rules (SB 1211 and AB 2533) make it easier to add detached living space. We evaluate what your specific lot allows and design the project to maximize its legal potential. Weighing a smaller footprint first? Compare a detached ADU or a home addition against a full rebuild before you commit.

How Long Does a New Home Take to Build?

A ground-up home in Chatsworth typically takes 14 to 24 months from contract to move-in: roughly 3–6 months for design and engineering, 2–5 months for LADBS plan check and permits, and 10–16 months of active construction depending on size, site conditions, and finishes. We give you a realistic milestone schedule up front and keep you updated at every phase, so there are no surprises.

What we actually see on Chatsworth new construction

Chatsworth has the largest lots and the most varied terrain in the northwest Valley, and both of those shape a new build more than the house design does.

Rock is a real budget line here. The Santa Susana formation runs through Chatsworth, and on the northern and western parcels we hit sandstone and boulders during excavation with some regularity. Rock changes trenching, foundation excavation and utility runs from a known quantity into an hourly one. A geotechnical investigation before design is not optional in this part of the Valley — it is the difference between a firm budget and an open one.

Very High Fire Hazard Severity Zone across much of the area. Chapter 7A applies to the exterior envelope: ignition-resistant materials, ember-resistant vents, Class A roofing and multi-pane glazing, plus defensible space and a noncombustible Zone 0 within five feet of the structure. On larger Chatsworth lots the fuel-modification plan can also affect where the house is allowed to sit.

Equestrian and K-district zoning still applies in places. Parts of Chatsworth carry equestrian overlays and larger minimum lot sizes, which change setbacks, accessory structure rules and what can be built alongside the main house. Homeowners are often surprised that the barn or accessory building they want has its own approval path.

Some parcels are not on city sewer. On the outer lots we still encounter septic systems. A new build on a septic parcel requires county environmental health review of the system capacity, and that review runs on its own timeline in parallel with LADBS plan check. Finding this out at design is routine; finding it out at permit is a delay.

Long driveways and long service runs. Large lots mean the distance from the street to the pad can be substantial — which affects fire-department access requirements, driveway grade and turnaround, and the cost of every utility run. Fire access alone has sunk more than one otherwise workable site plan.
