Fast, Reliable General Contractor Across Lompico
If you’re planning a remodel, addition, or ADU in Lompico, you’re not building in a typical suburban lot. You’re building on steep, wooded terrain in an unincorporated Santa Cruz Mountains community, and that changes everything about how a project gets permitted, priced, and built. A kitchen remodel in Lompico runs $14,000 – $45,000. A detached ADU typically lands between $90,000 and $220,000, largely because county permitting, geologic review, and site access drive costs here more than the structure itself. Call Toolbox Contractors at (855) 382-3257. We’ve done this work on Lompico’s roads and slopes, and we know exactly what county reviewers want to see before you break ground.
Why Toolbox Contractors Is Lompico’s Preferred General Contractor Company
Norm Castellano leads our team, and he’s spent years working mountain-rural builds where the land dictates more than the floor plan. Homeowners in Lompico keep calling us back because we scope the hard stuff first: slope stability, drainage, WUI fire clearance, septic and well setbacks. That’s not bonus expertise here. It’s the baseline for getting a project through Santa Cruz County permitting without stalling for months. We’ve built a reputation in Lompico for showing up when we say we will, quoting line-item numbers that hold, and being straight about what a hillside lot can and can’t support. Call (855) 382-3257 and ask for Norm, or talk to any of our project leads who know Lompico Road, West Drive, and the smaller offshoots off Old Town Road.
What separates us from a single-trade operator is scope. A Lompico homeowner adding a detached ADU usually needs a foundation, septic connection, electrical panel, roofing, and sometimes a retaining wall. We’re one licensed General Contractor who handles that entire sequence under one contract. No coordinating five trades across five schedules. One point of accountability from county submittal to final inspection.

Hire a General Contractor in Lompico
Hire a General Contractor in Lompico when you’re planning any project that touches structure, utilities, or ground. That includes additions, ADUs, garage conversions, and any remodel that moves walls or upgrades systems in a mountain home. Lompico’s stock is largely older cabins and hand-built homes on sloped parcels with private wells and septic, so remodels frequently uncover non-permitted prior work. A general contractor in Lompico is the person who untangles that, brings the job up to county code, and manages the subs. Expect an ADU to run $90,000 – $220,000. A home addition lands between $45,000 and $130,000. A garage conversion ranges $30,000 – $80,000. Those numbers account for Lompico’s permitting and site conditions, not just the lumber package.
What We Scope Before Quoting
Before we quote any Lompico project, we walk the parcel, check the county’s GIS for geologic and WUI overlays, and look at how equipment will reach the site. Narrow driveways and tight switchbacks off Lompico Road change the staging plan. If a concrete truck can’t make the turn, we adjust the foundation approach before we put a number on paper. That’s the difference between a quote that holds and one that surprises you mid-project.
Why a General Contractor Beats Piecemeal Hiring Here
On a sloped lot, every trade’s work touches the next. The excavator’s cut affects the foundation. The foundation’s elevation affects drainage. Drainage affects the retaining wall. When one contractor owns the sequence, those decisions get made in order, not in conflict. That’s why a Lompico addition is faster and cheaper in the long run with a single accountable General Contractor in Lompico than with three separate bids and a homeowner playing referee.
General Contractor Services in Lompico
General Contractor Services in Lompico span the full inside-and-out scope most mountain properties require. We remodel kitchens and baths, add rooms, convert garages, build decks, and construct detached ADUs and outbuildings. But the Lompico version of this work always includes the unglamorous parts: drainage swales, retaining walls, foundation waterproofing, and fire-resistant exterior assemblies. A bathroom remodel here runs $9,000 – $28,000. A paver patio on a sloped lot with proper base and drainage runs $3,500 – $11,000. A roof replacement on a redwood-shaded home costs $8,000 – $20,000, depending on slope and decking. The site work is never optional in Lompico, and we build it into every scope.
Kitchen and Bath Remodeling on Lompico Lots
An older cabin kitchen in Lompico often hides surprises: sagging floor joists, ungrounded wiring, or a sink drain that never met code. We demo carefully, inspect what’s underneath, and bring the room up to current Santa Cruz County standards before cabinets go in. KraftMaid and Wellborn cabinetry are our go-to lines because they hold up in humid, redwood-shaded homes. Cambria, Silestone, and Caesarstone countertops give you a surface that doesn’t warp or stain in a house that sees serious temperature swings.

ADUs and Detached Structures
Lompico’s unincorporated status makes it one of the more complicated places in the region to build an ADU. County permitting, geologic review, and WUI fire-clearance all apply on many parcels. We work with prefab manufacturers including Abodu, Dvele, Boxabl, and Plant Prefab where the site allows, and we do full site-built ADUs where the slope demands it. Either way, you get one contractor managing foundation, utilities, structure, and finish. That’s rare in this market.

AfterCommon General Contractor Problems We See in Lompico Homes
- Unpermitted prior work that fails current code. A cabin addition built in the 1980s without county sign-off can turn a simple kitchen remodel into a structural correction. We flag this in the walkthrough, not after demo starts, and we scope the fix so the permit doesn’t hang.
- WUI fire-clearance failures on decks and siding. Lompico sits in a wildfire hazard zone, and county inspectors reject decking, siding, and roofing that don’t meet defensible-space and ignition-resistance standards. We build to WUI code the first time so you don’t pay for rework.
- Slope creep and foundation movement after heavy winter rains. The Santa Cruz Mountains get real rainfall, and cut slopes on Lompico parcels move. We add drainage swales, retaining structures, and foundation waterproofing to every hillside scope we quote.
- Septic and well setbacks that shrink the buildable footprint. Many Lompico lots have a leach field and a well that already consume a chunk of flat ground. We check county health department records before we draw anything, so your ADU or addition lands where the county will actually approve it.
Pricing for General Contractor in Lompico, CA
These are real ranges for Lompico’s market, based on the lots, access, and permitting load we actually see here. They’re not flat-rate quotes because every Lompico parcel is different, but they give you a working number before you call.
| Project | Typical Lompico Range |
|---|---|
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |

| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
What pushes a Lompico job toward the top of those ranges: steep slope requiring engineered retaining, long equipment hauls, geologic report requirements, WUI upgrade work on the existing structure, and septic system modifications. We give free written estimates with line-item pricing, and we don’t change the number once we’ve walked the site and reviewed county records. Call (855) 382-3257 to schedule yours.

FAQs About General Contractor in Lompico
Yes. Lompico is unincorporated, so Santa Cruz County, not a city building department, reviews and issues your permits. Most ADUs and additions on hillside parcels also require geologic review and WUI fire-clearance, which means the permitting timeline runs longer here than in nearby incorporated towns. We handle the full submittal and respond to county correction letters so you don’t have to manage the back-and-forth. Call (855) 382-3257 for a free estimate and we’ll check your parcel’s overlays before you commit to anything.
Your septic tank, leach field, and well all have county-mandated setbacks from any new structure, and on a small Lompico lot that can shrink the buildable area dramatically. We pull county health department records during the scoping phase and position your addition or ADU where it will actually clear those setbacks. If the leach field needs relocating to make room, that’s a five-figure scope change we identify before permits, not after. Call (855) 382-3257 and ask us to check your parcel’s records.
Site access and slope stability, in that order. Many Lompico driveways off Lompico Road and West Drive can’t accommodate a full concrete truck, and steep grades require engineered retaining and drainage before any foundation goes in. We stage materials on pullouts, use smaller equipment where needed, and design drainage swales and retaining walls into the foundation scope from day one. That’s how projects on Lompico slopes pass final inspection without rework.
We use fixed, line-item pricing on a written scope, and we don’t issue change orders unless you approve them in writing first. If we uncover unpermitted prior work or slope issues during demo, we stop, document what we found, and give you a written change order with a clear price before any further work happens. That’s especially important in Lompico, where older cabins regularly hide surprises. Call (855) 382-3257 for a free estimate with no obligation.
Yes, and we’d argue it’s mandatory expertise here. Lompico sits in a Wildland-Urban Interface zone, and Santa Cruz County requires ignition-resistant siding, decking, and roofing assemblies on most parcels. We install James Hardie siding, GAF and Owens Corning roofing systems, and Class A fire-rated assemblies that pass WUI inspection. Building to WUI code from the start is cheaper than rebuilding after a failed inspection. Call (855) 382-3257 to discuss your project’s fire-safety scope.
