Asking rents on new-construction 1BR ADUs in the Bay Area cluster between $3,200 and $4,800 per month. Studios run $2,600–$3,800. 2BR units run $4,200–$6,200. The spread is driven by transit access, school district, and parking availability — not by ADU finish level.
Submarket medians (1BR, ~750 sq ft, new construction)
- San Francisco (Sunset, Richmond, Mission): $3,800–$4,800
- Oakland (Rockridge, Temescal, Piedmont Ave): $3,400–$4,200
- Berkeley (Elmwood, North Berkeley): $3,500–$4,300
- San Jose (Willow Glen, Rose Garden): $3,200–$3,900
- Peninsula (Palo Alto, Mountain View, Redwood City): $3,600–$4,600
What moves the median
Three factors drive 80% of the rent variance: walking distance to BART or Caltrain, public school district rating (Palo Alto, Piedmont, and SF District 5 schools command premiums), and whether the ADU includes off-street parking. Finish level matters less than landlords expect.
Yield math
A $360K Bay Area ADU at a $3,800/month median rent yields a 12.7% gross rent multiplier annualized, or roughly 6–7% cash-on-cash after vacancy and operating costs. Compare against the LA rent data and the LA-vs-Bay Area comparison.

FAQ · Cost
Common questions on cost
The questions readers send us most after this guide.
What kind of return on investment can I expect?
Across 120+ completed LA projects, our owners see 10–16% annual return on construction cost in long-term rental. The math: a $280K detached ADU renting at $2,800/month grosses $33,600/year — roughly a 12% gross yield before expenses. Property value uplift is typically 1.4–1.7× the build cost on appraisal.Are there grants or rebates available?
The CalHFA ADU Grant Program ($40K toward soft costs) was paused in 2023 but a successor is in late-stage legislative drafting. LADWP offers rebates for high-efficiency HVAC and induction cooktops. We track every active program and apply on your behalf.What does an ADU cost in LA?
Pricing depends on size, finish level, and site conditions. For 2026, our detached ADUs start around $250K for a 480 sq ft studio and run up to about $480K for a 1,200 sq ft custom build. Garage conversions begin around $145K. JADUs typically run $95K–$140K.What's included in your turnkey number?
Architectural and structural design, Title 24 energy compliance, full permit fees and plan check, soils report when required, foundation, framing, MEP rough-in, insulation, drywall, doors, windows, kitchen, bathroom, flooring, paint, fixtures, and final cleaning. Excluded: landscaping beyond grading, solar (offered separately), and LADWP service upgrades when the existing panel can't carry the load.How long does an ADU project take in Los Angeles?
Most detached ADUs run 9–13 months from contract to certificate of occupancy. Garage conversions are typically 4–6 months. Permitting alone is usually 60–120 days at LADBS depending on whether we use a pre-approved standard plan or a custom design that needs full plan check.What is the typical week-by-week breakdown?
Weeks 1–3: feasibility, survey, schematic design. Weeks 4–8: construction documents and Title 24. Weeks 9–20: plan check at LADBS or your local department. Weeks 21–24: site mobilization and foundation. Weeks 25–40: framing, MEP rough-in, drywall, finishes, and inspections. Final two weeks are punch list and closeout.

What does a ADU cost in San Francisco in 2026?
In San Francisco, a turnkey ADU typically starts around $240K and runs $480–$560 per square foot installed, depending on size, finish tier, and site conditions. Permit and impact fees layer $38K–$62K on top of construction, and City of San Francisco Planning & Building runs plan check 150–240 days on a clean submittal.What are the actual permit and impact fees for a ADU in San Francisco?
For a permitted construction scope in San Francisco, the City of San Francisco Planning & Building fee stack typically lands $38K–$62K all-in: plan check, building permit, school impact (when triggered), sewer capacity, and energy compliance review. The single biggest variable is utility capacity — PG&E service upgrades on pre-1980 panels add 6–10 wks.What is the per-square-foot price for a ADU in San Francisco?
Honest 2026 pricing for a ADU in San Francisco runs $480–$560 installed. Smaller footprints carry a higher $/sqft because fixed costs (kitchen, bath, utility tie-ins) spread over fewer feet. Bids that come in 20% under this band almost always exclude site work, Title 24, or impact fees — ask for a line-item breakdown before you compare.How can I make a ADU in San Francisco cheaper without compromising quality?
Four levers actually move the number in San Francisco: (1) use pre-approved standard plans where the jurisdiction publishes them — cuts plan check 30–45 days and trims design fees; (2) keep the footprint rectangular — every jog adds $3K–$6K of framing and roof complexity; (3) specify workhorse-tier finishes (LG STUDIO, Bosch 500, KraftMaid) instead of paid-name luxury — same daily UX at 35% lower spend; (4) sequence pg&e service upgrades on pre-1980 panels add 6–10 wks early to avoid schedule penalties.What does a garage conversion cost in San Francisco in 2026?
