$0 out of pocket

Nothing to lose. Everything to gain.

Most homeowners build using the equity already sitting in their property — so there's no cash down and no payments while we build. The new unit starts paying for itself the moment it's rented.

FAQ

Questions homeowners ask us

What is an ADU?

An ADU (Accessory Dwelling Unit) is a self-contained second home on your existing lot — a converted garage, an attached addition, or a detached backyard unit. In California and New York it can add rental income and value to your property.

How much does it cost me out of pocket?

Most homeowners build with $0 down by financing against the equity already in their home, with no payments while we build. Financing is subject to credit approval and varies by property.

Will checking my eligibility affect my credit score?

No. Our online check is a soft credit inquiry and does not affect your score. We never ask for your Social Security number on the website.

How long does it take to build?

A typical ADU is completed in about 4 to 6 months from permit approval, depending on the design, your city's process and site conditions.

Which ADU is right for my property?

You don't need to decide — we determine the best ADU type for your lot (garage conversion, attached, detached or JADU) at your free evaluation, based on your zoning, setbacks and goals.

Which areas do you serve?

We build across California — Los Angeles, Irvine, San Jose, San Francisco — and are expanding into New York. Enter your address to confirm availability in your area.

Who actually builds the ADU?

Every project is built by a licensed California team, ALLTIME MAINTENANCE INC (CSLB #1033999) — licensed and insured, with in-house crews rather than subcontracted middlemen.
