Custom Adu in Oakland

Oakland Custom ADUs

Whatever your Oakland lot allows — detached, converted, or tucked into the existing footprint — we design an ADU that fits it.

Oakland’s lots and homes shape what an ADU can actually be — a detached unit in a flat West Oakland backyard, a garage conversion off a Rockridge driveway, or a compact JADU carved out of an Oakland Hills home with limited grading room. We design around your lot and structure, not a one-size layout, and manage the process from site visit through move-in.

Building ADUs Throughout Oakland

Oakland’s lots vary block by block — narrow flat lots in West Oakland and Adams Point, wider backyards in Rockridge and Piedmont Ave, and sloped hillside parcels in the Oakland Hills. What that means for an ADU changes just as much: a detached unit needs yard space and clear access, a garage conversion depends on the garage’s existing structure, and a hillside JADU has to work around grading and access constraints. We evaluate what each lot and structure can actually support before we design.

Detached ADUs & Yard Access

Detached units need enough usable yard space plus a path wide enough for construction access and material staging. We assess setbacks, existing structures, and access during the site visit so the unit we propose is one that can actually be built and delivered.

Hillside Grading & Access

Oakland Hills lots often involve narrow, sloped driveways, retaining wall considerations, and limited staging space. We assess grading and access during the site visit so a detached or converted ADU is priced accurately up front.

Garage & Basement Conversions

For Oakland homes with existing garages or basements, we evaluate insulation, ventilation, ceiling height, and structural condition to determine whether a conversion meets code as a full ADU or is better suited as a JADU.

Utility & Meter Requirements

PG&E requires a dedicated electrical meter for new ADUs, and City of Oakland permitting has its own review timeline for ADU submittals. We plan utility coordination and permitting early so it doesn’t become a bottleneck later.

ADU Design / Build Process

1. Initial Site Visit: 1 to 1 ½ hrs

Every ADU starts with a vision, and this starts with a walkthrough to see what you have and understand what you want. By listening closely to your goals, vision, questions, and budget, we help you unlock the full potential of your ADU. With so many creative ways to configure compact spaces, whether it is a rental, guest suite, or a small home, it all starts with understanding how you want to live.

Step 1 – What To Expect

On site walkthrough to evaluate the starting point and discuss the overall goals of the project.
We provide a free ballpark construction cost, which will be a significant range.
This ballpark helps us understand if a client’s budget aligns with our estimated construction cost.
To proceed, we sign our preconstruction agreement (PCA), which includes the various services you will need to design and ultimately acquire the building permits.

2. Design & Material Selection: 3 - 4 weeks

Once the vision is clear, the design process brings it to life on paper. From countertops to cabinet layout to lighting, we’ll plan each detail with precision. A thorough design phase is key to staying on budget. Also, it’s often the fun part!

Consultations for all project goals and design considerations.
Some common design goals include careful attention around kitchen and bathroom design, lighting options, fixture selections, as well as exterior hardscape and landscape. The contractor creates an all-inclusive list of all project selections for client review and interaction. This single tool will be used to guide the project to the finish line.

3. Permitting: 2 - 3 months

Once the design is complete, it’s time to submit the plans to the city for approval. Approval time for an ADU can vary, but generally this will take around 2 – 3 months to get approved. The good news is that you can still keep the project moving! While most product selections will have already been considered, this is the time to actually start finalizing selections and shopping for items. Top on that list will often be key components for kitchen and bathroom, flooring, appliances, and fixtures.

4. Construction: 4 - 8 months

Finally, our team begins by carefully protecting your home and the surrounding areas. For attached ADUs, we install dust barriers with zipper doors and run HEPA air filtration to keep the air clean and the rest of your home undisturbed. Floor protection and other precautionary measures are also put in place. A dedicated team and project manager will carry out the work in coordination with the residents, with clear working hours established from the start.

5. Move In!

Upon passing our city final inspection, we will then do a thorough walkthrough, to ensure everything is just right. We will also provide and go over all of your new documentation, including manuals, warranties, etc., as well as provide a long term maintenance plan to help you make sure your ADU stays beautiful for years to come!

FAQ

You Ask We Answer

What's the first step if I'm considering an ADU in Oakland? +

Most projects start with a consultation or feasibility review. We assess your Oakland lot, existing structures, access, and zoning to help determine what's possible under the City of Oakland's ADU ordinances.

Can I build a detached ADU on a small or hillside Oakland lot? +

In many cases, yes, especially with new state regulations that have loosened restrictions. We begin with a site and zoning analysis specific to your Oakland property, including grading and access for hillside parcels.

Do you handle Oakland's ADU permitting and inspections? +

Yes. We manage permitting and inspections directly with the City of Oakland to keep the project compliant and moving forward smoothly.

Do I need to upgrade utilities for an Oakland ADU? +

Yes. PG&E requires a dedicated electrical meter for all newly constructed ADUs, even if one already exists on the property. New gas depends on several factors, and EBMUD does not require a new water meter for an ADU on a single-family lot.

Can a garage conversion in an older Oakland home qualify as an ADU? +

Often, yes, depending on the garage's existing structure and condition. We evaluate insulation, ventilation, ceiling height, and structural capacity at the site visit and flag any upgrades needed to meet code.
