Prices are Boxabl's, as published on boxabl.com and checked October 11, 2026; Boxabl can change them. “Unit only” is the home as it leaves the factory. Boxabl's turnkey price is its own all-in package and a useful benchmark. Ordering through ADU Concepts, the site work is priced for your lot after a free review, in an itemized, written proposal. California status is as announced by Boxabl; we confirm it for your model before you order.
04How it works
We check zoning, setbacks, utilities, slope, the path for the truck and crane, and whether your lot sits in a fire hazard zone. You learn whether a Casita fits, and which one.
Pick the size and floor plan, then the exterior, roof, and outdoor additions. You get one itemized, written proposal for everything on site.
We prepare the site plan, foundation and utility engineering, and energy compliance, then file the ADU permit. State law requires a decision on a complete ADU application within 60 days.
Boxabl builds the home in its factory while we pour the foundation and bring water, sewer, and power to the pad.
The Casita arrives folded on a truck, a crane sets it on the foundation, and it unfolds on site. Boxabl says the unfold takes about an hour.
We connect the utilities, seal and finish the exterior, build the roof, steps, or patio you chose, and walk it through final inspection.

Pitched roof
A site-built gable roof with Class A rated shingles, like this Casita in a Southern California backyard. It is the single change that makes a Casita look like it belongs with the house.

Board and batten, lap siding, or a two-tone paint scheme, detailed for the Casita's panels.
A 200 sq ft covered patio adds an outdoor room more than half the size of a Studio, on its own structure.
A landing, steps, or a ramp sized to your door and your grade.
Two Casitas joined by a covered breezeway make a courtyard home. It has to be planned from the start.
Pavers, lighting, fencing, and planting, so the new home looks like it was always there.

07California rules
Boxabl announced state approval for the Casita Studio in 2024 and the Two Bedroom in December 2025. The state approves and inspects the factory-built home; your city or county permits and inspects the foundation, utilities, and site work.
On a single-family lot, a Casita is permitted as an accessory dwelling unit under state law: 4 ft side and rear setbacks, no owner-occupancy rule, and a decision within 60 days of a complete application.
Distance to property lines, fire separation, the height of an added roof, utility capacity, and the path for the truck and crane are all lot-specific. We check every one in the first review.
Lots in a Very High Fire Hazard Severity Zone carry extra exterior construction rules. We tell you plainly whether a Casita fits your lot, and when a steel-framed ADU is the better path, we say so.
