Our Services
Every path to an accessory dwelling unit
From a detached backyard home to a junior unit inside your walls, ADU Center covers the full range - and connects you with vetted local pros for each one.
SERVICE 01
Detached ADUs
A detached ADU is a fully independent home in your backyard, with its own foundation, walls, roof, kitchen, and bathroom. It is the most flexible ADU type - ideal for family, guests, a home office, or long-term rental income - and gives you complete separation from the main house.
What’s Included
- Site evaluation, layout, and utility planning
- New foundation and full framing
- Complete kitchen and bathroom
- Electrical, plumbing, and HVAC connections
- Insulation, drywall, flooring, and finishes
- Private entrance and exterior finishing
What Affects Cost
- Total square footage and number of rooms
- Site access, grading, and soil conditions
- Distance to existing utility connections
- Level of interior and exterior finishes
- Local permit, plan-check, and impact fees
SERVICE 02
Two-Story ADUs
When a lot is tight, building up instead of out keeps more of the yard open. A two-story ADU stacks living space over a smaller footprint - often living, kitchen, and bath below with bedrooms above - and calls for engineered structural design to do it right.
What’s Included
- Engineered two-story structural design
- Reinforced foundation for vertical loads
- Interior staircase and upper-floor framing
- Full kitchen, bath, and living areas
- Utilities routed across both levels
- Exterior cladding, windows, and roofing
What Affects Cost
- Structural engineering and foundation depth
- Height, setback, and zoning requirements
- Stair placement and interior layout
- Square footage across both floors
- Finish level and window packages
SERVICE 03
Garage Conversions
A garage conversion reuses a structure you already have, turning an underused one- or two-car garage into a warm, code-compliant living unit. Because the shell and slab often stay in place, it can be one of the most efficient ways to add an ADU.
What’s Included
- Reframing walls, insulation, and moisture control
- New windows, doors, and code-required egress
- Kitchen or kitchenette and full bathroom
- Upgraded electrical and plumbing rough-in
- Heating, cooling, and ventilation
- Flooring, drywall, and interior finishes
What Affects Cost
- Condition of the existing slab and structure
- Adding or relocating a bathroom
- Any required replacement parking
- Insulation and weatherproofing upgrades
- Permit requirements in your jurisdiction

SERVICE 04
Junior ADUs (JADUs)
A junior ADU is a compact unit of up to 500 square feet created within the existing walls of your home - often a converted bedroom. JADUs include an efficiency kitchen and a separate entrance, and may share a bathroom with the main house, which keeps the scope lean.
What’s Included
- Interior conversion within the existing footprint
- Efficiency kitchen with cooktop and sink
- Separate exterior entrance
- Optional private or shared bathroom
- Sound insulation and interior partition
- Finishes to match a comfortable living space
What Affects Cost
- Whether you add a dedicated bathroom
- Creating a new separate entrance
- Scope of the efficiency kitchen
- Electrical and plumbing modifications
- Local permitting and inspection fees
SERVICE 05
ADU Design & Planning
Every good ADU starts with a plan. Design and planning turn your goals and your lot into a build-ready set of drawings - confirming what will fit, how it will function, and what your local jurisdiction will expect before a single wall goes up.
What’s Included
- Feasibility review of your lot and goals
- Floor plans and space planning
- Site plan showing placement and setbacks
- Structural and engineering coordination
- Material and finish direction
- A drawing set ready for permit submittal
What Affects Cost
- Custom design versus pre-approved plans
- Lot complexity, slope, and access
- Number of design revisions
- Engineering and survey requirements
- Level of detail and 3D visualization
SERVICE 06
Permitting & Approvals
Permitting is where many ADU projects stall. Our network handles the paperwork - checking zoning, preparing and submitting the permit package, responding to plan-check corrections, and coordinating inspections so your project keeps moving.
What’s Included
- Zoning and eligibility review
- Permit application and document package
- Plan-check submittal and corrections
- Coordination with utility providers
- Scheduling and managing inspections
- Guidance through final approval
What Affects Cost
- Requirements of your local jurisdiction
- Impact, utility, and school fees
- Number of plan-check review rounds
- Utility connection and upgrade needs
- Project size and complexity
