Frequently Asked Questions

Do I need a contractor to build an ADU?

It’s not always legally required, but hiring a licensed ADU construction contractor is strongly recommended to ensure code compliance, proper permits, and a smooth construction process.
 
Common mistakes include underestimating ADU construction cost, skipping permits, poor floor plan choices, hiring unlicensed contractors, and not planning utility connections early.

Costs vary by design, materials, and site conditions, with larger detached ADUs falling on the higher end of ADU cost per square foot. A free ADU estimate gives the most accurate pricing for your property.

Foundation work, utility connections, and permitting/engineering fees are typically the biggest cost drivers, especially on lots with difficult site conditions.
We build detached ADUs, garage conversion ADUs, attached ADUs, and custom backyard ADUs based on your property needs.
Yes, garage conversion ADUs are one of the most popular and cost-effective ways to add living space and rental income.
A garage conversion ADU is usually the most affordable option, followed by junior ADUs (JADUs), since both use existing structures and require fewer new utility connections.
