Fast, Reliable General Contractor Across Hidden Hills
Finding a general contractor in Hidden Hills, CA means hiring someone who understands what this city actually demands: hillside lots, strict dual-plan review, and homes where the finish level is high enough that a sloppy rough-in gets expensive fast. We coordinate full-scope work here weekly, from kitchens and baths to room additions and ADUs. You get a written scope of work, a real allowances sheet, and a draw schedule before demo starts. No verbal estimates that quietly grow. Call (803) 680-2547 and we’ll walk your property, check the grading, and map out the sequence so your permit sign-off isn’t the thing holding up your finish date.
Key Takeaways:
- Hidden Hills requires dual review from the city’s building department and Los Angeles County fire and hillside grading rules. We sequence rough-in and driveway approach work together so inspection sign-offs don’t stall each other.
- Every Mason Remodeling project gets a written price before any work begins, plus a 365-Day Done Right Promise that covers fixes for a full year from completion.
- Kitchen remodels in Hidden Hills run $14,000 – $45,000, bathrooms $9,000 – $28,000, and home additions $45,000 – $130,000. Your written estimate locks those numbers in before demo day.
Why Mason Remodeling Is Hidden Hills’s Preferred General Contractor Company
We don’t expect homeowners to open their gates to strangers. That’s why every crew member arrives pre-verified under The Threshold Standard: you get each technician’s name and photo sent to you before the visit, and when they arrive at your Hidden Hills door, they’re in a clean marked uniform and show a photo ID badge. It’s a named, trademarked process, not a courtesy. You know exactly who is stepping onto your property before they ever do.
Mason Remodeling has been handling general contracting, bathroom remodeling, and whole-home projects since 2004 as part of the Threshold Group family. Isaac Pruett leads our work with the kind of protectiveness Hidden Hills homeowners understand: you’re not handing your house to a process, you’re handing it to people you’ve seen and can name. That matters when you’re often home alone, raising young kids, or you’ve lived in this city long enough to have seen a few contractor horror stories from neighbors off Long Valley Road.
Hidden Hills homeowners get something else from us that the general market doesn’t provide as standard: a written price before any tool is unpacked. Not a ballpark. Not a verbal range. A written price, on every project, every time. If a repair or installation fails within 365 days of completion, we return and make it right at no cost to you. The guarantee terms are stated plainly in writing, including what’s covered, what’s excluded, and for how long.
Styles & brands we work with
Construction Company in Hidden Hills
Construction Company work in Hidden Hills starts with understanding that your property sits on at least one acre and the city’s building department reviews plans against hillside grading and fire-defensible space requirements on top of the county’s Title 24 energy rules. That dual review means we have to sequence structural rough-in and the private driveway approach early, because the second inspection sign-off cannot be scheduled until the first is closed. If a contractor doesn’t know that, your permit timeline gets compressed and your draw schedule stalls. We know it. We plan around it from week one.
Structural and Rough-In Scope
A room addition or ADU on a Hidden Hills hillside lot often means footing work, shear wall upgrades, and drainage that accounts for how water moves off your slope during winter rains. We pull the permits, coordinate with the city and county reviewers, and keep the structural rough-in moving so your inspection sign-off isn’t waiting on a missed signing. Home additions in Hidden Hills typically run $45,000 – $130,000 depending on square footage, hillside foundation work, and finish level.
Access, Hauling, and HOA Rules
Hidden Hills has private roads and HOA haul-route rules. We check those before a single dumpster or truck rolls through your gate, because a fine from the association plus a stalled draw schedule is a real cost nobody wants. Garage conversions here run $30,000 – $80,000, and a clean access plan keeps that number from creeping.
Remodeling Contractor in Hidden Hills
Remodeling Contractor work in Hidden Hills means protecting the bones of a house while upgrading it, and the projects we see most are kitchens, primary baths, and whole-home refreshes on ranch and estate properties along Round Meadow Road and the gated streets off Long Valley Road. Kitchen remodels in Hidden Hills run $14,000 – $45,000. Bathroom remodels run $9,000 – $28,000. The spread comes down to cabinetry grade, countertop selection, and whether you’re moving plumbing or keeping the existing footprint.
Kitchen and Bath Scope
We use specification-grade cabinet lines like KraftMaid and Wellborn, and countertops from Cambria, Silestone, and Caesarstone. That means your Hidden Hills remodel gets professional-grade materials with real warranty backing, not whatever the box store had on sale. Kohler and Moen fixtures are standard options, and we match existing cabinet and counter brands when you’re doing a partial refresh rather than a full gut.
Whole-Home and Multiple-Room Work
When a Hidden Hills homeowner is doing several spaces at once, we phase the work so you’re not living in a full construction zone for months. The allowances sheet keeps cabinetry, tile, and fixture decisions from turning into arguments at the end of the job. One written scope, one draw schedule, one set of expectations.
Trusted Brands We Service in Hidden Hills
We’re direct with Hidden Hills homeowners about which product lines we install and service: KraftMaid and Wellborn cabinetry, Cambria and Silestone surfaces, Kohler and Moen fixtures, and GAF roofing. If you’re considering a prefab or panelized ADU, we’ve worked around Abodu and Dvele systems and can integrate their shell with your site work, foundation, and finishes. We stock common replacement parts locally for Hidden Hills customers, so a warranty callback doesn’t mean a two-week wait on a part from somewhere else. You call, we show up with the right piece.

AfterCommon General Contractor Problems We See in Hidden Hills Homes
- Bidding from photos and a verbal description. It happens constantly. A contractor gives a number, then mid-project the allowances for cabinetry, tile, and fixtures become a fight because nothing was in writing. We write the scope first. Every line item, every allowance, every draw.
- Missing the dual city and county plan review. Hillside lots here trigger grading and fire-defensible space review on top of Title 24. If your contractor doesn’t sequence rough-in and driveway approach work together, the inspection sign-off window collapses and your schedule slips by weeks.
- Running trucks through a narrow private drive without checking HOA haul-route rules. Hidden Hills streets are private and the association enforces haul routes. A missed check means a fine and a stalled draw schedule. We check before the first truck arrives.
- Opening walls without structural sign-off. We’ve been called to Hidden Hills homes where a previous contractor removed a load-bearing wall without a beam. The subfloor deflects, the island settles, and the fix costs twice what the original shortcut saved. We pull permits and do the load path right the first time.

FAQs About General Contractor in Hidden Hills
Yes, Hidden Hills requires permits for any kitchen or bathroom remodel that touches plumbing, electrical, or structural work, and the city’s building department reviews plans against hillside grading and fire-defensible space rules in addition to county Title 24 energy requirements. We pull all permits for you and get the inspection sign-offs before you use the space. Call (803) 680-2547 and we’ll tell you exactly which permits your project triggers.
A home addition or ADU in Hidden Hills typically runs 6 to 14 months depending on hillside foundation work, dual city and county plan review, and inspection scheduling. The dual review is the variable most contractors miss. We sequence rough-in and driveway approach work together so one sign-off doesn’t wait on the other. Call (803) 680-2547 for a realistic calendar specific to your lot.
Change orders after framing closes, hillside footings that require more concrete than planned, and HOA haul-route restrictions on private roads. We prevent most of this by putting a written scope, allowances sheet, and draw schedule in front of you before demo starts. When a change order is needed, like when we added a load-bearing header on that Hidden Hills ranch off Round Meadow Road and had to cut a new beam pocket, it gets signed before framing closes, not discovered later. Call (803) 680-2547 to get your project scoped properly.
Yes, we match existing KraftMaid, Wellborn, Cambria, Silestone, and Caesarstone lines when you’re doing a partial remodel or adding a kitchen island to an existing run. We also install Kohler, Moen, Toto, and Grohe fixtures that match what’s already in your Hidden Hills home. Call (803) 680-2547 and we’ll verify your existing model numbers and confirm what’s still in production.
No, and you shouldn’t trust a general contractor who does. Planned construction work like kitchens, bathrooms, additions, and ADUs in Hidden Hills requires permits, review cycles, and a real schedule. What we do offer is a live person who answers the phone 24 hours a day, 7 days a week, so when you call about your project, you talk to a human, not a voicemail loop. Call (803) 680-2547 and we’ll schedule your free estimate and get the paperwork started the right way.
If you’re planning a remodel, addition, or ADU in Hidden Hills, start with a written scope and a real price. We’ll walk your lot, check the grading and access, and give you a plan that accounts for the dual permit review before it becomes a delay. Call (803) 680-2547 to schedule your free estimate today.
