Got questions?

Frequently asked questions.

What is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential lot. It can be attached to the main home, detached in the backyard, or a converted existing space like a garage or basement.
Is ADU Home List free for homeowners?
Yes. Browsing floor plans, watching project videos, reading articles, and contacting pros is free for homeowners. You only pay the manufacturers, builders, or lenders you choose to work with.
How much does it cost to build an ADU?
Costs vary by size, location, design, and finishes — typically $100,000 to $400,000. Prefab and modular options often reduce cost and timeline compared to site-built units.
How do pros list their business?
Pick a plan on the pricing page, then add your floor plans, publish articles or videos, and start engaging in the forums — all from your dashboard.
What are boosts and how do they work?
Boosts elevate a listing's placement in search and featured slots. You can also boost your overall profile to gain visibility across categories. Manage both from your dashboard.
Do I need a permit to build an ADU?
Virtually all ADU projects require permits from your local city or county. Our partner pros are familiar with local regulations and can guide you through the process.
How long does it take to complete an ADU project?
Most projects take 6 to 18 months from planning to move-in. Prefab units are typically faster; custom site-built projects may take longer due to design and permitting.
