Our crews know East Foothills well. We’ve built on the steep lots off Sierra Road, worked around the drainage patterns near Alum Rock Avenue, and coordinated foundations on the expansive clay that runs through the Toyon area. That local knowledge matters when a 12% slope triggers a geologic hazard review and your schedule suddenly depends on a soils report and a retaining wall. We’re the Home Addition Contractor team homeowners call when they want the price fixed in writing before the first nail goes in.
Why Lodgewick ADU San Jose Is East Foothills’s Preferred Home Addition Contractor Company
Russ Delmar leads our East Foothills work, and he’s spent years navigating the specific permitting and grading challenges this hillside throws at every project. Homeowners here aren’t looking for a sales pitch. They want a straight answer on what a bedroom addition off a daylight basement will cost, whether the slope will require a retaining wall, and when the custom cabinetry will actually arrive. That’s what we provide.
Every job we take in East Foothills operates under The Kingswell Guarantee. A written price before work begins. A defined arrival window. A clean job site. And a written guarantee on every project, with a free return visit if the work fails within the 365-day period. We don’t ask homeowners to trust us on faith. We put it in writing.
Our East Foothills customers regularly tell us the same thing: other contractors bid without a soils report, then came back with a change order once they hit clay or a slope they hadn’t planned for. We don’t do that. If the hillside ordinance requires a soils report, we tell you before we bid, not after demolition starts.
Bathroom Addition Contractor in East Foothills
A bathroom addition in East Foothills typically runs $55,000 – $110,000 when built as part of a larger addition, with the variation driven by finishes, slab condition, and whether the hillside triggers a retaining wall. As a Bathroom Addition Contractor serving East Foothills, we coordinate the soils report, structural engineering, and custom tile or stone work so the price you sign is the price you pay.
Slab and Slope Considerations First
Most East Foothills homes are 1960s – 1980s ranchers and split-levels with original slabs that have cracked and settled over decades. Before we frame a new bathroom, we check what’s under it. If the slab has dropped 2 inches like one we found off Sierra Road, the bathroom goes on deep piers, not the existing grade.
What High-End Finishes Do to Your Timeline
Custom vanities, architectural glass shower enclosures, and specialty tile are ordered after design is locked, and the lead times run 10 – 14 weeks. On an East Foothills bathroom addition, that means ordering before framing starts. If the finishes are ordered late, the job stalls at rough-in and your bathroom sits unfinished while everyone waits on a shop drawing.
Bedroom Addition Contractor in East Foothills
A bedroom addition in East Foothills generally runs $120,000 – $250,000, depending on whether you’re adding a single room or a bedroom with a bath and walk-in closet. As a Bedroom Addition Contractor working East Foothills hillsides, we budget for foundation work, drainage, and fire setback compliance from day one, so the number you approve matches the invoice at the end.
Daylight Basements and Split-Level Tie-Ins
Many East Foothills homes have daylight basements or split-level layouts that make a bedroom addition structurally more complex than a flat-lot build. Tying new framing into a settled 1970s slab requires an engineer’s letter and usually deep piers. We handle that coordination so you don’t have to chase a structural engineer on your own.
Passive Cooling for East Foothills Summers
East Foothills runs hotter and drier than the valley floor. A new bedroom that faces the afternoon sun without proper orientation turns into an oven by July. We plan window placement, roof overhangs, and insulation from the start, and we can spec James Hardie siding for its fire resistance and durability against the seasonal heat.
Trusted Brands We Service in East Foothills
We work directly with leading ADU and addition brands including James Hardie, Tuff Shed, and Abodu, sourcing materials and coordinating prefab components that fit East Foothills lot sizes and slope conditions. Because we order these brands regularly for East Foothills projects, we know the lead times and can lock orders early, so your custom millwork and architectural glass arrive when the framing is ready, not ten weeks after.
Common Home Addition Contractor Problems We See in East Foothills Homes
- Bidding without a soils report. A contractor gives you a number, then discovers expansive clay or a 12% slope after demolition. The city’s geologic hazard review kicks in, and your permit timeline stretches by weeks while your budget grows by thousands for site prep and a retaining wall.
- Ordering custom finishes after framing starts. Custom millwork, cabinetry, and architectural glass take 10 – 14 weeks from shop drawings to delivery. If the order goes in late, the whole job stalls and your family lives in a construction zone months longer than planned.
- Misreading drainage and fire setbacks. East Foothills lots drain fast in winter downpours, and the city enforces fire setback rules on hillside properties. A design that ignores either gets flagged during plan review and sent back for redesign, costing you time and money on top of the original bid.
- Tying into a settled slab without an engineer. The original slabs on East Foothills ranchers and split-levels have settled and cracked for 40 – 60 years. Framing on top of them without deep piers or an engineered slab means your new addition starts moving with the old foundation.

FAQs About Home Addition Contractor in East Foothills
Nearly every one. East Foothills’ hillside ordinance treats any slope over 10% as a geologic hazard zone, and most residential lots here exceed that threshold. A soils report is typically required before the city will review your permit, and the findings often dictate the foundation design. Budget $2,500 – $5,000 for the report and expect it to add 2 – 4 weeks to your timeline. Call (669) 266-4319 and we’ll tell you whether your lot is likely to trigger the requirement before you spend a dollar.
Custom millwork, cabinetry, and architectural glass are the three biggest schedule drivers, each with 10 – 14 week lead times from shop drawings to delivery. The calendar is set by these orders, not by labor. We lock the design and order these materials before framing starts so the job doesn’t stall at rough-in. Call (669) 266-4319 for a project timeline built around your finish selections.
We write a line-item price based on the final design, selected finishes, and known site conditions including your soils report and any retaining wall requirements. The price is fixed in writing before we order anything. If you change a finish mid-project, we update the written price and you approve the change before anything is purchased. No surprises at the door. Call (669) 266-4319 to get your written estimate.
Sometimes, but not always. Many East Foothills garages sit on slabs that have settled badly, and some are built into slopes where the city’s geologic hazard review makes conversion impractical. We’ll assess your slab, the slope, and the existing drainage before telling you whether a conversion makes sense or a detached addition is the better play. Call (669) 266-4319 and we’ll give you a straight answer.
Because the hillside ordinance treats slopes over 10% as a geologic hazard zone, and cutting into a hillside to place a foundation changes the load on the soil above and below. A retaining wall stabilizes that cut and keeps winter downpours from eroding the slope into your new foundation. Retaining walls in East Foothills typically run $15,000 – $45,000 depending on height and length, and they add 3 – 6 weeks to your schedule. Call (669) 266-4319 to get a site-specific assessment.
