Sun Valley is not a single-neighborhood suburb. It’s a patchwork of equestrian-zoned ranches north of Glenoaks Boulevard, post-war single-family homes around Stonehurst Avenue, and light-industrial stretches along San Fernando Road and Tujunga Avenue. That mix changes how a general contractor should scope, price, and build here. Our General Contractor team knows which permits go through LA City and which ones go through LA County, which is not a small detail when your property sits on a septic system and well rather than municipal sewer and water.
Why Mason Remodeling Co Los Angeles Is Sun Valley’s Preferred General Contractor Company
We have spent years working inside Sun Valley’s specific permitting reality. A simple kitchen remodel near the 91352 ZIP can stay entirely within city building codes. But a room addition or detached ADU on a large lot north of Glenoaks often crosses into LA County territory: septic setbacks, well clearances, grading and drainage plans, and health department sign-offs. Homeowners don’t discover this mid-project when working with a contractor who knows the area. We scope it before quoting, so the written price includes what the county will actually require.
Every Mason Remodeling crew member is background-checked, identity-verified, and arrives in a clean marked uniform. You receive the technician’s name and photo before the visit, and they show a photo ID badge at the door. That process is called The Threshold Standard, and it applies to every job we run in Sun Valley. The company is led by Isaac Pruett, and we carry the same standard across every project since Mason Remodeling was founded in 2004 as part of the Threshold Group family of home-service companies.

Styles & brands we work with
Hire a General Contractor in Sun Valley
Hire a General Contractor in Sun Valley when the work involves permits, multiple trades, or structural changes to a home on a large or irregular lot. This is the core service for Sun Valley homeowners adding square footage, converting a garage, or building a detached structure. A home addition runs $45,000 – $130,000. A garage conversion runs $30,000 – $80,000. Those ranges assume your property already has municipal sewer and water. If it doesn’t, the scope changes and the written price reflects that before we start.
Septic and Well Verification Before Quote
Many Sun Valley homes north of Glenoaks Boulevard still rely on aging septic systems and private wells. Before we quote an addition or ADU, we verify which system your property uses, check the fixture load your current septic tank can handle, and confirm well setbacks. If the county requires a septic tank replacement or a new leach field, that becomes a line item in the written price, not a surprise change order.
County-Level Permitting on Acreage
Sun Valley sits inside LA city limits, but county rules govern many large-lot and equestrian-zoned parcels. Grading plans, drainage calculations, and health department approvals often apply before framing begins. We pull the permits, coordinate the inspections, and pass them, then fold the paperwork into one fixed written price.
General Contractor Services in Sun Valley
General Contractor Services in Sun Valley cover the full build: kitchens, bathrooms, whole-home remodels, room additions, ADUs, and detached structures like shops and garages. A kitchen remodel runs $14,000 – $45,000. A bathroom remodel runs $9,000 – $28,000. A paver driveway on a large equestrian lot runs $7,000 – $18,000. Every line item is written down before work starts.
Detached ADU and Outbuilding Construction
We build detached ADUs and workshops on Sun Valley’s larger lots. The work often requires equipment access paths, concrete pumping coordination, and seismic-rated footings. Our crew recently completed a detached ADU on a 1950s ranch-style lot near Stonehurst Avenue, where we had to mediate county well and septic setbacks, cut a graded access path for a concrete pumper, and pour new load-bearing footings to meet LA seismic codes before the first wall went up. That project included a KraftMaid kitchenette with Cambria counters and a Moen faucet.
Whole-Home and Ranch House Remodeling
Sun Valley’s ranch-style homes from the 1950s through 1970s often hide subfloor rot, outdated foundation bolts, and wiring that no longer meets code. A full gut remodel means opening those unknowns and pricing the fix before it becomes an emergency. We inspect first, quote second, and never start swinging hammers without a written price on the table.

AfterCommon General Contractor Problems We See in Sun Valley Homes
- Septic systems run past capacity when remodels add fixtures. A kitchen remodel that adds a pot filler or second sink can push an aging septic tank beyond its designed load. The county then requires a tank replacement or leach field expansion, and that work runs in the tens of thousands before framing begins.
- Long material hauls and awkward equipment access on large lots. Sun Valley’s equestrian-zoned properties are often deep and irregular. Getting a concrete truck, pumper, or framing materials to the back of a half-acre lot may require a temporary graded access path. Contractors who don’t plan for that underbid the job and then bill the difference.
- Grading and drainage plans on open lots can double the scope. LA County requires grading and drainage plans for many detached structures on open Sun Valley lots. That engineering work happens before construction starts, and a contractor who skips it is guessing. We include it in the written price.
- Santa Ana winds expose weak framing and unsecured roofing. Sun Valley sits in the San Fernando Valley’s wind path. Older ranch homes with original roof sheathing and unbraced gable ends fail first in big wind events. Wind-resistant tie-downs and roof repairs are part of the scope on any remodel we run here.

FAQs About General Contractor in Sun Valley
Yes, in many cases you need both. A detached ADU on a Sun Valley lot outside city sewer and water service often triggers LA County health department review for septic setbacks and well clearances, even when the City of Los Angeles has already issued a building permit. The county approval comes before final ADU sign-off. We handle both tracks in our scope, so the written price covers the full permitting path. Call (213) 632-5711 for an exact quote on your lot.
It can add $15,000 to $40,000 or more if the county requires a septic tank replacement or expanded leach field before approving the addition. The added bathroom or kitchen fixtures increase the load on the existing system, and a tank that has been in the ground since the 1960s often fails that review. We verify your system’s capacity before we ever quote the addition, so the written price reflects reality. Call (213) 632-5711 to schedule a site visit.
We specify roof tie-downs, braced gable ends, and wind-rated sheathing on structures built on Sun Valley’s open lots. Santa Ana winds funnel through the San Fernando Valley and hit unshielded ranch homes hard. The details go into the written quote, not get discovered mid-build. Call (213) 632-5711 for a free estimate that includes wind-resistant scoping.
Yes, LA County typically requires a grading and drainage plan for any detached structure beyond a certain square footage on an open or equestrian-zoned Sun Valley lot. The engineering work happens before construction starts and can add weeks to the timeline. We include that engineering cost in our written price so there’s no second invoice later. Call (213) 632-5711 and we’ll scope your specific lot.
We price the known scope up front, then include an allowance line for unknowns we expect based on the home’s era and condition. In a 1950s Sun Valley ranch, we commonly find rotted subfloor near original kitchens and baths, foundation bolts that predate current seismic code, and wiring that needs replacement. Those items are listed as allowances in the written price with a clear cap, not left open-ended. Call (213) 632-5711 for a detailed walkthrough of your home.
