Frequently Asked Questions About Building an Oakland ADU
1. How long does it take to build an ADU in Oakland?
Most Oakland ADUs are completed in 10-126 to 9 months from signed contract to keys. Garage conversions move faster (8 to 103 to 5 months including time taken for design and permitting). Detached new builds take longer (107 to 129 months). The design and permitting phase isPermits are typically 15 to 20 4 to 10 weeks of that.
2. How much does an Oakland ADU cost?
The cost of an Oakland ADU depends on the size, layout, site conditions, utility requirements, and whether you are building a detached ADU, garage conversion, or attached unit. Rather than giving a generic estimate that may not reflect your property, our team reviews your goals, lot conditions, and scope to help you understand the likely budget range and all in costs before you move forward.
Garage conversions start around 1810K, depending on size, site, condition of the garage and other factorsk. Attached ADUs run 180k to 320k. Detached ADUs run 220k to 420k. The exact number depends on size, finishes, lot conditions, and design complexity. We provide a fixed price contract before construction begins.
3. Do I need to live in the main home to build an ADU?
Under current Oakland and California rules, owner occupancy is generally not required for new ADUs permitted on or after January 1, 2020. AB 1033 also allows you to sell your ADU separately as a condo in cities that have opted in. Usually, no. For most standard ADUs in Oakland, you do not need to live in the main home to build or rent out the unit. Rules are different for Junior ADUs where owner occupancy is required and certain property-specific situations, so our team can help you confirm what applies to your property.
4. Can I rent out my ADU?
Yes. Long term rentals (30+ days) are allowed citywide in Oakland. Short term rentals are subject to city specific rules. Most of our clients see $2,000 to $4,000 per month in rental income depending on size and neighborhood.
5.What is included in your quote?
Our quote covers design, permit documentation, structural plans, full permit processingtting, project management, interior design support, all construction labor, standard finishes, and connection to existing utilities. We will list out exactly what is included and what is not before you sign anything.
6. Do I need a special lot to qualify for an ADU?
Most single family lots in Oakland qualify. State law allows at least one ADU and one Junior ADU on most residential parcels. Setback requirements are 4 feet from side and rear lot lines. We confirm feasibility on your free site visit.
7. Can you finance the project?
We do not directly lend, but we work with several Bay Area lenders that specialize in ADU loans, HELOC, and renovation refinances. We can introduce you to lenders during the consultation.
8. What if I am not ready to build right now?
That is completely fine. Many of our clients start with a free feasibility quote 6 to 12 months before they actually build. We will hold your design and pricing for 90 days while you make a decision.
