Why Lodgewick ADU Builders Is Santa Clarita’s Preferred Home Addition Contractor Company
Most Santa Clarita homeowners come to us after a bid fell apart. Sometimes it was a price that changed at the door. Sometimes an HOA design-review board sent plans back over a stucco color nobody flagged. Russ Delmar leads our crew, and he’s spent enough time in Newhall Land’s master-planned tracts to know that a Santa Clarita addition is never just a construction project. It’s a compliance chain: HOA design review, city plan check, fire-hardening requirements where they apply, and the documentation your insurer will want later. We handle all of it, and we put the whole scope in writing before you sign.
Every Lodgewick addition operates under The Kingswell Guarantee. Written price first. Defined arrival window. Clean job site. A written guarantee on every job, and if the work fails within 365 days, we come back and make it right. Free. A live person answers our phones 24/7. Not a voicemail loop. When you call about your permit or your framing inspection, you get a person.
We work with leading prefab and materials brands like Abodu, Cover, Dvele, and James Hardie, matched to your lot, budget, and the specific code layers on your parcel. On a Canyon Country hillside lot inside a CAL FIRE Very High Fire Hazard Severity Zone, that match matters more than anywhere else in the Santa Clarita Valley. Call (254) 602-5618 and ask for a written estimate. We’ll show up in the window we give you.
Room Addition Contractor in Santa Clarita
A Room Addition Contractor in Santa Clarita handles ground-level additions built onto the existing footprint: extra bedrooms, expanded kitchens, a home office, a larger family room. Most Santa Clarita room additions land in the $72,000 to $168,000 range for 400 square feet, though HOA design review and fire-hardening requirements on hillside parcels can push that figure higher. We price it all before we start. You’ll see the number before you sign, not after demolition.
Tract home setbacks and HOA review
Most of Santa Clarita’s housing stock is 1980s and 1990s Newhall Land tract construction with consistent setbacks and utility stub locations. That consistency works in your favor for a room addition, but it also means your HOA’s design-review board has seen hundreds of similar applications and has specific aesthetic demands. We re-cut plans to the tract’s original palette before submission. It saves weeks.
When a bump-out makes more sense
A bump-out addition extends a single room by 2 to 6 feet, often without a full foundation pour. In Santa Clarita, bump-outs run about $40,000 to $85,000 and are popular in Valencia paseo homes where a full rear addition would crowd the lot. For a kitchen or dining nook, it’s the cost-effective move. We’ll tell you if a bump-out actually serves your space better than a full addition, and we’ll put either price in writing.
Second Story Addition Contractor in Santa Clarita
A Second Story Addition Contractor in Santa Clarita builds up instead of out, adding a full or partial upper level over an existing single-story home. Second-story additions here run $240,000 to $390,000 for a typical 800-square-foot project, and the engineering load requirements are substantial. You’re adding weight to a foundation that wasn’t originally designed for it, and you’re raising the roofline. In Santa Clarita, that roofline has to satisfy two masters before you ever get a permit.
Roofline aesthetics and the HOA
In Valencia, we picked up a second-story addition after the homeowner’s first bid stalled at the HOA design-review board over the stucco color and roofline. Our crew re-cut the plans to the tract’s original palette and included James Hardie ignition-resistant siding and ember-resistant vents. The same package sailed through city plan check. That’s the difference between a contractor who reads the CC&Rs and one who treats the HOA as an afterthought.
Chapter 7A fire hardening on hillside parcels
Large portions of Canyon Country and Saugus sit inside CAL FIRE-designated Very High Fire Hazard Severity Zones. If your parcel is mapped there, a second-story addition pulls Chapter 7A requirements into your project: ignition-resistant siding, ember-resistant vents, and defensible-space setbacks. Materials cost climbs 8 to 15 percent. Plan check takes longer. A bid that skips this layer looks cheaper until the city kicks it back, and then you’re paying twice. We pull the CAL FIRE FHSZ map before we finalize any proposal.
Trusted Brands We Service in Santa Clarita
We install and service additions built with James Hardie siding, Abodu prefab panels, Cover modular systems, and Dvele high-performance envelopes. Because our crews work Santa Clarita regularly, we keep common trim profiles, ember-resistant vent stock, and Hardie color-matched touch-up materials close at hand, not a week out from a distant warehouse. That’s not convenience. It’s the difference between a plan-check resubmission taking five days or five weeks. Ask us which system fits your parcel’s code layers and your budget. We’ll match it, not push one brand.
Common Home Addition Contractor Problems We See in Santa Clarita Homes
- Bids that skip the HOA design review. Most Santa Clarita additions run on a dual track: HOA approval of exterior materials and setbacks first, then city permit submission. A bid that treats the HOA as a formality blows up at plan check.
- Canyon Country parcels inside a VHFHSZ. After the 2019 Tick Fire, homeowners in Canyon Country discovered mid-project that their parcels trigger Chapter 7A fire-hardening requirements. Their initial bids never priced it in. We pull the CAL FIRE FHSZ map before we bid, every time.
- Unrated fire-resistive assemblies. A VHFHSZ parcel requires tested, documented compliance that an insurer will actually accept, not whatever assembly was cheapest at the supply yard. If your addition is on a hillside, the materials documentation matters as much as the materials.
- Missing the insurance paper trail. Santa Clarita sits in a hot inland basin with severe Santa Ana wind events. When a claim comes, your insurer asks for proof that the work met code at the time it was built. We document every compliance layer and give it to you before you ever need it.

FAQs About Home Addition Contractor in Santa Clarita
Yes. California’s post-2020 ADU statutes stripped HOAs of the power to prohibit ADUs, but additions still run through mandatory HOA design-review processes for exterior materials and setbacks. Your HOA reviews the elevation, finish palette, and roofline before the city accepts your permit application. Budget two to six weeks for that step. Call (254) 602-5618 if you want us to pull your CC&Rs and map the actual review path before you commit to anything.
On a VHFHSZ parcel in Canyon Country or Saugus, Chapter 7A requires ignition-resistant siding like James Hardie, ember-resistant vents, and defensible-space setbacks. On a flat Valencia tract lot, standard stucco and code-compliant assemblies typically pass, but your HOA may require specific colors and profiles. We match the product to the parcel’s code layers before we bid. That keeps the number honest. Get a written quote at (254) 602-5618.
Yes. We pull the CAL FIRE FHSZ map for every Santa Clarita addition estimate, so our written price includes Chapter 7A materials where your parcel requires them. You won’t get a surprise line item after plan check. That’s the Kingswell Guarantee: written price first, every time. Call (254) 602-5618 to start.
If a Santa Ana wind event or wildfire damages your addition, your insurer will ask for proof the work met code when it was built. We document every compliance layer, including Chapter 7A materials and HOA approvals, and hand you the file when we finish. That paper trail is the difference between a settled claim and a denied one. For a free estimate, call (254) 602-5618.
HOA design review first, then city plan check, then construction inspections, and on VHFHSZ parcels a fire-hardening verification layer as well. Most Santa Clarita additions clear the full path in three to nine months depending on scope and HOA responsiveness. We manage every step and tell you where your project is at any point. Call (254) 602-5618 and we’ll walk you through your specific parcel’s path in writing.
This is the only Santa Clarita addition page that treats the HOA design-review track, the CAL FIRE VHFHSZ Chapter 7A layer, and the insurance-claim record as one connected compliance chain rather than three separate line items. That’s the spine of every quote we write. If you want a contractor who treats your addition the same way, call (254) 602-5618 and ask for a free written estimate. We’ll show up in the window we give you, leave your job site cleaner than we found it, and put the guarantee in writing before the first nail goes in.
