Share Our Passion for ADUs

Los Angeles needs more homes. 

Many have proposed big and grandiose solutions to reducing the cost of housing. But we prefer small plans. We believe one small home in your backyard can make a big difference.

As of 2017, you can now easily put an independent Accessory Dwelling Unit on your property. It’s simple really. You have property, and we have all the tools to design, permit and build you a beautiful little structure.

Step 2: Schedule a Phone Consultation

Free  |  15 minutes

Provide us with some basic information such as your address and we'll send you an email to schedule a free 15-minute phone consultation with one of our experts. We'll review your property online and help determine if one of our ADUs is right for you.

Step 3: ADU Feasibility Study

$600 - $1,000  |  2 weeks

We come out to your property to answer questions in-person, take measurements, and study existing conditions.  Then we prepare a preliminary site plan indicating the possible location and size of your ADU. Based on this analysis we provide you a preliminary cost estimate for all the work.


Step 4: Design, Engineering, and Permitting

$20,000 - $30,000  |  2-4 months

We'll send you an Agreement covering the architecture, engineering and permitting portion of the process, which is paid in two installments. Our one-stop-shop services mean you won't need any outside consultants. We handle it all.

Step 5: Construction

$99,000 - $399,000  |  2 - 6 months

As we get close to obtaining the building permit, we will finalize the Construction Agreement which includes a detailed budget estimate and schedule. Then we build your ADU, providing you with daily updates along the way. Billing occurs monthly. You pay as you go. No upfront costs.

Cost and timeline will depend on your site and the type/size ADU you select.

In most Los Angeles Neighborhoods, ADUs can earn you $8,000 - $18,000 per year in net rental income and $100,000's in additional property value.
