ADU Pricing · 2026
How Much Does a 2-Bedroom ADU Cost in California? (2026)
A 2-bedroom ADU in California costs $339,000 to $449,000 when you build with Framework First, and that figure already carries a permitting budget along with plans, foundation, the factory-built home, delivery, utility hookups, appliances, and final inspection. Where you land in that range depends mostly on the size and bathroom count you choose, and your exact permit costs get confirmed for your property in the feasibility study.
The short version: Framework First builds six different 2-bedroom ADU floor plans, from the 660 sq ft Six Sixty 2BR at $339,000 to the 945 sq ft Nine Forty-Five 2/2 at $449,000. Every price is turnkey and done-for-you. Two bedrooms is the single best layout for rental income, because two rooms rent for far more than one in the same footprint.
What “all-inclusive” actually means
Most ADU price quotes you will see online are not real totals. They cover the structure, then leave you to find out about site work, permits, the foundation, hookups, and finishes later. By the time you add those, the “affordable” ADU has grown by six figures.
Framework First works the opposite way. The number we quote already carries a permitting budget, not a rough placeholder added later. It already includes:
- A permitting budget and plans (drawn, submitted, and managed by our team; exact permit costs are confirmed for your property in the feasibility study)
- The foundation
- The home itself, built about 97% in our Salinas factory
- Crane delivery and set
- Utility hookups (electrical, plumbing, sewer)
- Appliances
- Final inspection and sign-off
We anchor on the total, because the total is what you write checks against.
2-bedroom ADU prices at Framework First
Here are our six 2-bedroom floor plans with exact, current pricing. All are part of our 14-model lineup, ranging across our three styles: Classic Craftsman (our standard), Urban Farmhouse, and Ultra Modern.
| Model | Size | Layout | All-Inclusive Price* | Delivery |
|---|---|---|---|---|
| Six Sixty 2BR | 660 sq ft | 2 bed / 1 bath | $339,000 | ~5 months |
| Seven Forty-Nine | 749 sq ft | 2 bed / 2 bath | $369,000 | 5 to 6 months |
| Eight Eighty-Five 2BR | 885 sq ft | 2 bed / 1 bath | $399,000 | ~6 months |
| Nine Forty-Five 2/1 | 945 sq ft | 2 bed / 1 bath | $419,000 | ~6 months |
| Eight Eighty-Five 2/2 | 885 sq ft | 2 bed / 2 bath | $429,000 | ~6 months |
| Nine Forty-Five 2/2 | 945 sq ft | 2 bed / 2 bath | $449,000 | ~6 months |
*Includes a permitting budget, not final permit costs. Permits and property-specific site work (septic, retaining walls, etc.) vary by property and are confirmed in your feasibility study.
A few things worth noticing in that table:
- The cheapest way into two bedrooms is the Six Sixty 2BR at $339,000. It packs two real bedrooms into our most-loved 660 sq ft footprint. That is only about $30,000 more than the same-size one-bedroom version, and you get a whole extra room that pays for itself in rent.
- A second bathroom adds roughly $30,000. Compare the Eight Eighty-Five 2BR ($399,000, one bath) to the Eight Eighty-Five 2/2 ($429,000, two baths), or the Nine Forty-Five 2/1 ($419,000) to the 2/2 ($449,000). For high-end rentals or two unrelated adults sharing, that second bath often earns its cost back.
- Bigger is not always pricier per room. The 945 sq ft Nine Forty-Five 2/1 ($419,000) gives you nearly 1,000 square feet of two-bedroom living for the most space in its class.

Why a 2-bedroom ADU is the smart rental play
If your goal is rental income, two bedrooms is almost always the right call. Here is the logic our account managers walk owners through every week.
A second bedroom does not double your build cost, but it can dramatically increase your rent. In most of our service area, going from a one-bedroom to a two-bedroom unit adds a meaningful jump in monthly rent, while the build cost only rises by the price of one extra room. That spread is exactly what drives a strong return.
Two bedrooms also widens your tenant pool. A small family, two roommates, or a couple that wants an office all need that second room. A one-bedroom locks you into singles and couples only.
We dig into the actual dollar math, by city and by model, in our guides on how much rent an ADU can earn in California and California ADU rental laws. The short version: the Six Sixty 2BR is the highest-ROI rental in our lineup, which is exactly why we tag it “Best for Rentals.”
What drives the price up or down
Within the 2-bedroom range, three things move your number:
Size
A 660 sq ft home costs less than a 945 sq ft home. Simple. But bigger is not automatically better. Two bedrooms in 660 square feet rents nearly as well as two bedrooms in 945, so the smaller footprint is often the better return. Build what your tenant or family actually needs, not the biggest box that fits.
Bathrooms
One bath or two. A second bathroom adds about $30,000. It is worth it when two independent adults will share the space, or when you are targeting premium rents. It is not worth it for a single tenant or a family that is comfortable sharing.
Site conditions
This is the one variable that lives outside the model price. Steep slopes, long utility runs, difficult crane access, or unusual soil can add site-work cost. We do not guess at this. Our feasibility study puts a real number on your specific lot before you commit a dollar, so there are no surprises.

How the price compares to a home addition
Owners often weigh a backyard ADU against adding two bedrooms onto the main house. The build costs can land in a similar range, but an ADU gives you something an addition cannot: a separate, rentable, independently metered unit that adds its own income and resale value. We compare the two side by side in ADU vs home addition.
Frequently asked questions
What is the cheapest 2-bedroom ADU you build?
The Six Sixty 2BR at $339,000 all-inclusive. It fits two real bedrooms into a 660 sq ft footprint and delivers in about five months. It is also our top pick for rental income, because two bedrooms rent for far more than the modest cost bump over a one-bedroom.
Does the price really include everything?
Yes, with the usual caveat: a permitting budget, plans, foundation, the factory build, delivery, utility hookups, appliances, and final inspection are all inside the number, though your exact permit costs are confirmed for your property rather than fixed in advance. The one variable we cannot quote sight-unseen is unusual site work, and that is exactly what the feasibility study measures for your lot.
How long does a 2-bedroom ADU take to build?
Most of our 2-bedroom models deliver in five to six months, because about 97% of the home is built in our Salinas factory while your site work and permits happen in parallel. That is far faster than site-built construction. See how long it takes to build an ADU for the full timeline.
Can I legally build a 2-bedroom ADU on my lot?
In most cases, yes. California law lets you build a detached ADU up to 1,200 sq ft on a single-family lot, and cities must allow at least 800 sq ft. There is no bedroom-count limit in state law. Local zoning and setback details vary, which we confirm for free. Read our plain-English California ADU laws 2026 guide for the full picture.
Is a 2-bedroom worth more than a 1-bedroom?
For rental income and resale, almost always. A second bedroom adds modestly to your build cost but meaningfully to your rent and your appraised value. We cover the resale side in ADU appraisal and resale value.
