Detached ADU
Standalone backyard units designed for privacy, daylight, and strong rental or family-use flexibility.
ADU Builder in the San Francisco Bay Area
Design-build ADUs for Bay Area homeowners who want clarity, predictability, and a finished space that feels intentional and original to the property.
Bay Area ADU Design-Build, Done Right
An ADU is not just a backyard building—it’s a permitted living space with utilities, inspections, and real-world constraints. We coordinate the details so the experience stays calm and the outcome stays excellent.
Permit-aware planning
We coordinate planning/building submittals and maintain a clear review cadence—so permitting stays proactive, not reactive.
Design-build accountability
One team responsible for scope clarity, construction sequencing, and closeout—reducing misalignment and delays.
Refined, move-in-ready finish
Durable assemblies, clean detailing, and a finished interior prepared for immediate use.
ADU Types We Build
Every site is different. We start with feasibility, then recommend the best ADU approach for privacy, access, and long-term value.
Attached ADU
Integrated ADUs that expand living space while maintaining functional separation and architectural continuity.
Garage Conversion ADU
Code-compliant conversions that optimize an existing structure while respecting zoning and structural constraints.
Design-Build Process
A Clear Path from Feasibility to Closeout
We keep complexity manageable with documented milestones—so your ADU stays predictable, permit-aware, and built to last.
Site Constraints & Scope Clarity
We review access, utilities, setbacks, privacy needs, and your end goal (rental, family, office). This informs the recommended ADU type and scope.
Layout, Windows, and Finish Direction
We coordinate layout and finish direction for a space that feels calm, bright, and functional—without overdesigning the budget.
Submittals & Review Coordination
We coordinate planning/building submissions and maintain a clear permit-tracking cadence. When engineering is required, we collaborate with your selected engineer and design team.
Construction & Inspections
Milestone scheduling, clean job-site discipline, and consistent communication—so inspections and final handoff stay smooth.
ADU Costs & Timelines — What to Expect
Costs and schedules vary across the Bay Area due to utilities, access, site conditions, and permitting review. During consultation, we outline feasibility, sequencing, and major cost drivers so expectations are clear before construction begins.
Site & access
Hillside conditions, narrow driveways, and tight staging can change sequencing and logistics.
Utilities
Location of water, sewer, gas, and electrical tie-ins can materially affect scope and timeline.
Permitting & reviews
Agency review cycles and revisions vary by jurisdiction and project complexity.

ADU FAQs
Straight answers to common questions. Exact requirements vary by city and site; we’ll confirm during consultation.
Do you coordinate ADU permits?
Yes. We coordinate planning/building submittals and track reviews and revisions. When engineering is required, we collaborate with your selected engineer and design team.
What types of ADUs do you build?
Detached ADUs, attached ADUs, and garage conversion ADUs—customized to setbacks, privacy needs, access, and utility constraints.
How long does an ADU take?
Timelines vary based on permitting review cycles, site conditions, and scope complexity. We provide a realistic sequence and milestones during consultation.
Can the ADU match my home’s architecture?
Yes. We prioritize architectural continuity—proportions, material transitions, and window/door rhythm—so the ADU feels original to the property.
Do you build across the entire Bay Area?
Yes. We serve East Bay, Marin, and Silicon Valley communities. Explore your city page for local context and constraints.
What happens after I reach out?
We review your goals and site constraints, then outline feasibility, recommended ADU type, and next steps for design, permitting, and construction.
