ADU Company in Newhall, CA
An ADU in Newhall is rarely a simple backyard project. The foothill parcels, older housing stock, and fire-zone requirements that define this part of the Santa Clarita Valley shape nearly every build we take on. Lodgewick ADU Builders handles accessory dwelling units, garage conversions, and home additions here with written pricing before any work starts, plus a 365-Day Done Right Promise on every job. If you’re weighing an ADU in Newhall, call (254) 602-5618 and we’ll walk you through what your specific lot actually needs.
Our Main Newhall Services
Most Newhall homeowners come to us for one of three things: a detached ADU in the backyard, a garage conversion that turns an old single-car structure into rentable or family space, or a home addition that adds square footage to the main house. Each has its own page with local pricing and specifics, linked below.
Home Addition Contractor in Newhall
Adding onto a Newhall home means working around the valley’s heat, the occasional Chapter 7A fire-zone requirement on hillside lots, and an original footprint that often dates to the 1940s or 1950s. The goal is square footage that feels like it was always there, with a foundation, roof, and HVAC plan matched to a lot that may slope more than you realize. For the full local breakdown, see our Home Addition Contractor in Newhall page.
Garage Conversion Contractor in Newhall
Those single-car detached garages scattered through Old Town Newhall and the surrounding core neighborhoods are ideal conversion candidates, but they almost always need more than drywall and a floor. Undersized 100-amp panels, original galvanized supply lines, and decades of valley heat take their toll, and the City of Santa Clarita won’t final a permit until the electrical and plumbing are brought current. See the full scope and pricing on our Garage Conversion Contractor in Newhall page.
ADU Builders in Newhall
A detached ADU on a Newhall foothill lot can trigger California Building Code Chapter 7A: ember-resistant vents, Class A roofing, and ignition-resistant siding. That’s a real cost line item, and it has to be identified before plans are drawn, not after. We handle the parcel lookup, the design work, and the build, and we put the price in writing first. Details are on our ADU Builders in Newhall page.

Why Newhall Homes Are Different
Newhall sits in a valley bowl ringed by dry chaparral hillsides, and it regularly records some of the hottest summer temperatures in the greater LA region, frequently above 105°F. That’s not a trivia point. It means an ADU here needs an HVAC system sized for real heat load, not a plan pulled from a coastal template.
Then there’s the fire zone question. Large portions of Newhall’s foothill and canyon-adjacent parcels fall within CAL FIRE’s Very High Fire Hazard Severity Zone, or VHFHSZ. On those lots, any new detached ADU or addition must comply with California Building Code Chapter 7A, which governs ember-resistant vents, Class A roofing, and ignition-resistant siding. That single designation can add $20,000 to $40,000 to an otherwise straightforward detached ADU build, and it has to be confirmed via parcel lookup before design even begins. Finding out after plans are drawn means expensive redesigns and permit restarts.
Older homes add another layer. Many houses in Old Town Newhall and the surrounding core neighborhoods were built between the 1940s and early 1970s, and plenty still have 100-amp electrical panels, original galvanized supply lines, and single-car detached garages. Those are all workable, and they’re often exactly what makes a garage conversion or ADU addition make sense financially. They just require panel upgrades and re-piping before the City of Santa Clarita will sign off on the permit.

What pushes a Newhall ADU toward the top of these ranges is almost always the same short list: a VHFHSZ parcel designation, a slope that needs retaining or engineered foundation work, or an older main house whose electrical and plumbing have to be brought up to code while you’re at it. Whatever the number is, you’ll have it in writing before we start, and it won’t change at the door.

FAQs About ADU Company in Newhall
Once a parcel determination and design are complete, most Newhall projects can start within two to six weeks, depending on permit processing and material lead times at the City of Santa Clarita. Fire-zone parcels typically add design time up front. Call (254) 602-5618 for a current schedule.
Yes, on many foothill and canyon-edge parcels. If your lot is in a CAL FIRE Very High Fire Hazard Severity Zone, your ADU must meet California Building Code Chapter 7A, which affects vents, roofing, and siding. We confirm this with a parcel lookup before design starts. Call us for a free estimate.
