A garage conversion in Moraga typically runs $120,000 – $280,000 for a high-end studio or one-bedroom ADU with custom finishes, and most projects take 7 – 12 months from design approval to move-in. The hillside lots, strict geotechnical requirements, and long lead times on architectural glass and custom millwork mean you need a contractor who knows this town’s specific rules before the first drawing gets stamped. That’s what we do. Call (707) 760-0502 and we’ll give you a written price before any work begins.
Our Garage Conversion Contractor team has worked on steep lots along Camino Pablo, Rheem Boulevard, and throughout the Sanders Ranch and Rancho Laguna neighborhoods. We know where the clay soils shift, where the bedrock sits shallow, and what the Design Review Board wants to see before they’ll sign off on your garage-to-ADU project. That local knowledge is the difference between a permit that sails through in two months and one that bounces back three times.
Why Lodgewick ADU San Francisco Is Moraga’s Preferred Garage Conversion Contractor Company
Lodgewick ADU Builders is the ADU company of the Kingswell family, established in 2010. Russ Delmar leads our Bay Area team, and he’s spent years learning the contours of Moraga’s housing stock: 1950s – 1970s ranch-style and split-level homes on large hillside lots, many with older foundations and tight construction access. We understand what those lots demand before we quote them.
Every Moraga project runs under The Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee delivered before we drive the first stake. If the work isn’t right, we come back and make it right. That’s our 365-Day Done Right Promise, and it’s in writing on every single project. No exceptions.
Background-checked, uniformed technicians show up at your door, and a live person answers our phone 24/7. When you call with a question about your Moraga build or your guarantee, you won’t sit in a voicemail loop. You’ll talk to someone who knows your project.
Garage Conversion Permit in Moraga
A Garage Conversion Permit in Moraga is the approval from the Town of Moraga that lets you legally convert an existing garage into living space, and it’s the step that trips up more homeowners than any other part of the process. Moraga’s hillside development rules are stricter than flatland Lamorinda neighbors, and the permit path here often requires geotechnical review, hillside drainage plans, and design review before the building department will issue anything. Plan on $8,000 – $25,000 in permit fees, plan check, and related engineering costs, depending on lot slope and scope.
Geotechnical and Foundation Review
On many Moraga lots, the permit office will not accept a standard slab-on-grade foundation without a geotechnical report first. Expansive clay and shallow bedrock are common along the town’s ridgelines, so the report often triggers a pier-and-grade-beam foundation design. That adds cost, but it’s the correct path, and we price it into your written quote from day one.
Design Review and Hillside Standards
Moraga’s Design Review Board looks at sight lines, massing, and hillside setbacks. A garage conversion that’s invisible from the street still has to meet the town’s aesthetic standards. We handle the drawings, the submittals, and the revisions, and we tell you what the board will flag before they flag it.
Garage Conversion to Living Space in Moraga
Garage Conversion to Living Space in Moraga means taking a 400 – 600 square foot garage built in the 1950s to 1970s and turning it into a legal, comfortable studio, one-bedroom, or office – and on these older hillside homes, that usually means reinforcing the structural framing, replacing the slab, and reworking drainage before any finish work starts. Expect to budget $130,000 – $260,000 for a complete conversion with proper insulation, electrical, plumbing, and finished interiors. Permits, engineering, and long-lead finishes are included in that range if they’re part of your scope.
Foundation and Structural Work
Older Moraga garages sit on floors that were poured for cars, not for living space. Retrofitting for a legal ADU means cutting into that slab, adding proper footings and moisture barriers, and often anchoring into hillside with deeper piers. We do this work every week on lots from Buckhorn Ridge to Corliss Canyon.
Custom Finishes and Long-Lead Items
If you’re doing a high-end conversion with architectural glass, rift-sawn cabinetry, or specialty tile, the lead times drive the schedule. It’s not the framing crew that sets your move-in date; it’s the glass wall being fabricated and the millwork shop routing your cabinet order. We lock your price before we order those items, so you’re never caught with a change order after the deposit clears.
Trusted Brands We Service in Moraga
We work with established ADU brands and materials that hold up to Moraga’s hillside conditions. For garage conversions, we regularly specify James Hardie siding and trim for fire resistance on brush-adjacent lots, Plant Prefab for certain detached configurations where a modular panelized approach works, and Tuff Shed structures where a simpler, code-compliant shell makes sense for storage or a base build. Because we order these materials directly and track lead times ourselves, Moraga customers get honest schedule dates, not guesses. If you’re considering any of these brands for your conversion, we can tell you what works on your specific lot and what doesn’t.
Common Garage Conversion Contractor Problems We See in Moraga Homes
- Shallow bedrock surprises. On Camino Ricardo, our crew converted a 1963 split-level’s attached garage into a studio ADU. We coordinated with the owner’s architect and a geotechnical engineer after hitting shallow bedrock. The fix added piers and time, but the fixed price held.
- Long-lead finishes derailing schedules. Custom rift-sawn oak cabinetry from a San Francisco millshop ran 14 weeks; a thermally broken sliding glass wall ran 9 weeks. We ordered both as soon as the drawings locked, which is why the project finished on schedule instead of four months late.
- Hillside drainage failures. Winter storm runoff pools against new foundations on sloped lots and triggers erosion-control citations. We plan drainage at the design stage on every Moraga hillside conversion, not after the first rain.
- Permit re-designs after geotech review. A standard slab-on-grade drawing gets kicked back when the town asks for the geotech report. We drill first, design second, so the permit path stays linear.

FAQs About Garage Conversion Contractor in Moraga
On hillside lots in Moraga, yes, the Town typically requires a geotechnical report before approving a conversion, especially where expansive clay or shallow bedrock is present. Flat lots near the Moraga Country Club area may skip it, but if your parcel slopes, plan for the report and the piers it may trigger. Call (707) 760-0502 and we’ll tell you whether your lot is likely to need one before you spend a dollar.
Plan on 7 – 12 months for a high-end conversion with custom millwork, architectural glass, and design review. The long-lead items, not the labor, set the calendar: custom cabinetry can run 10 – 14 weeks and a thermally broken sliding glass wall 8 – 12 weeks. We order those as soon as your drawings and permits lock, so your move-in date doesn’t slip past what we quoted.
In many cases, yes, and keeping the existing roof structure can save $10,000 – $30,000 versus rebuilding. But on 1960s-era split-levels in neighborhoods like Sanders Ranch, the roof framing often needs reinforcement to meet current seismic and load requirements for living space. We’ll inspect the structure and tell you what’s worth saving.
Moraga sits in a wildland-urban interface zone, so the Town’s building code requires fire-rated exterior materials on converted garages near brush or hillside open space. James Hardie fiber cement siding, tempered-glass windows with ember-resistant vents, and class-A roofing underlayment are the common standards. We specify these on every hillside conversion from day one, not as a code catch-up after plan check.
Because the expensive items on this tier of work, custom glass, millwork, and engineered foundations, are ordered months before they arrive, and their cost is known the day you order them. We give you a written price before we place those orders, so there’s no surprise when the glass wall shows up and no “market adjustment” later. That’s The Kingswell Guarantee, and it’s in writing before work begins. Call (707) 760-0502 for an exact quote on your garage. Estimates are free.
