Everything families ask, answered.

Our 14 configurations range from $199,000 for a 450 square-foot studio to $599,000 for a 1,200 square-foot U-shaped 3-bedroom. Every price is all-inclusive, with a permitting budget built in along with plans, foundation, the factory build, delivery, hookups, appliances, and final inspection. Permit costs are set by your city and county, so they are property-specific and confirmed during your feasibility study.

Not once your contract is signed. We confirm property-specific costs, like permit fees, septic work, or retaining walls, during your feasibility study and customization phase, before you sign. After that, your contract price is fixed, with no surprise change orders.

Nearly everything. Our pricing is all-inclusive, from $199,000 to $599,000, with a permitting budget built in along with plans, foundation, the factory build, delivery, hookups, appliances, and final inspection. Permit costs are set by each city and county, so they are confirmed in your feasibility study rather than baked into the sticker price. Property-specific site work, like septic upgrades or retaining walls, is not in the listed model price either, though we handle it in-house as part of your contract so the whole project stays with one builder. We own our factory, so there is no marketplace markup, and once your feasibility study confirms those numbers and you sign your build contract, the price is fixed, with no surprise change orders.

Most ADUs are delivered in 4 to 6 months from contract signing, subject to your city's permitting timeline. The 4-month figure is a best case on our Four Fifty, our smallest model. Our largest 1,200 square-foot homes take 7 to 9 months. We build 97% of the home in our factory in parallel with the foundation work.

Seven: a free property analysis, a free factory tour, a free site visit, the feasibility study ($497 standard, or $997 for an empty lot), a review of the findings, customization in the ADU Designer, and then build and delivery. Full detail is on our process page.

Yes, and we encourage it. We are one of the few ADU builders in the area whose factory you can walk through before you buy.

Yes, we handle the process for you: site plan, Title 24, structural, and city submissions. You never coordinate with the city yourself. Every price includes a permitting budget, but actual permit fees are set by your city and county, so they are property-specific and confirmed during your feasibility study.

A few real advantages, current as of 2026. Cities must approve or deny a complete ADU application within 60 days, no public hearing required, so you're not waiting on a discretionary review process. If your ADU is under 750 square feet, state law waives transportation, park, and school impact fees entirely, a real savings on a smaller model. And the old requirement that you live on the property to build an ADU has been permanently removed, so you can build one purely as a rental if that's your goal. Cities can still layer on local requirements, and your specific city and lot are confirmed in your free property analysis.

California state law allows detached ADUs up to 1,200 square feet in most cities. Every model we build fits within that state limit. Your specific lot and local rules are confirmed during the feasibility study.

Usually not. State law waives replacement parking if your property is within half a mile of public transit, or when the ADU replaces existing garage space. We confirm this for your lot.

No. We partner with two specialized ADU lenders, Mason Mac and SearchLight Lending, who handle HELOCs, construction loans, and cash-out refinances. We can introduce you.

Most borrow against their existing home’s equity with a HELOC or a construction-to-permanent loan. Our calculator shows estimated monthly payments for any model.

We use 2x6 exterior wall framing, 50% thicker than the industry-standard 2x4 and better insulated, and we build in a climate-controlled factory, so there is no weather damage during construction. Every home meets Title 24 energy compliance and CALGreen standards.

Quality control is far higher indoors, the build runs in parallel with your foundation work (saving months), and there are no strangers on your property for months. A site-built home of the same size typically takes 16 to 24 months. Ours arrives finished and is craned into place in a day.
