How it works
From vacant lot to leased homes
Each project follows four stages. KBG manages the construction path from site selection through completion.
Acquire the lot
Identify infill lots zoned for multifamily density, then complete due diligence, design and City of Phoenix permitting.
Install Casita units
KBG pours foundations, runs utilities, sets the factory-built units by crane and builds the stairs, walkways and decks.
Lease up
Completed studios are offered for rent with professional property management.
Hold or sell
The property is held as a rental or sold, as set out in the project's offering documents.
Why BOXABL Casitas
A factory-built studio, installed by a licensed Arizona contractor
- Factory-built. Each Casita is built in a factory and delivered to the site, so on-site work focuses on foundations, utilities and installation.
- 19' × 19' studio, 361 sq ft. 9'6" ceilings, 8' doors and windows, a full-size kitchen and a full bathroom.
- Approved in Arizona. The BOXABL Casita (two-door model) is currently the BOXABL model approved for installation in Arizona.
- KBG handles the build. Kingdom Builder Group is an Arizona BOXABL dealer and installer and a licensed general contractor (AZ ROC #348837) managing site work, permits, utility connections and installation.

Planned Casita multiplex projects
Four projects are in planning: two 4-plexes and two 8-plexes. Each project is a separate offering with its own offering documents. Investing in one project does not give an interest in any other. Sites have not been selected, so location and land cost are TBD.

About these figures: Each project is a separate offering through its own project LLC, and figures are shown per project. Equity raise goals and total project costs are preliminary estimates from our pro forma base case (equity goal = estimated total project cost less an estimated loan) and will change when a site, land cost and financing are set. "Raised" counts only investments accepted under signed offering documents. Locations and land costs are not yet set. Any offering will be made only to verified accredited investors through that project's offering documents. No returns are shown or implied. Investing involves risk, including possible loss of capital.
Site and layout
How the building works
Front stairs land at the upper front doors. Private rear decks serve the upper units. Unit fronts face an on-site parking lot with a landscaped strip and front walk, not a street.

Frequently asked questions

The minimum investment is $25,000. Terms, eligibility and risks are described only in offering documents provided to qualified investors.
What are the terms and expected returns?
Terms are provided to qualified investors through offering documents. We do not publish projected returns on this page. Investing involves risk, including possible loss of capital.
Are stacked Casita buildings approved?
These are design concepts. Each project requires structural engineering for the two-story design, multifamily zoning, and City of Phoenix plan review and permits before construction.
