Los Angeles ADU Construction

ADU Construction Built for Extra Income or Extra Family Space

From detached backyard units to attached and junior ADUs, we design and build accessory dwelling units that meet California code and add real, usable space to your property.

Build Equity & Flexibility

A Second Unit That Pays for Itself

An accessory dwelling unit is one of the most effective ways to add value, rental income, or space for extended family to a Los Angeles property. But ADUs come with their own set of zoning rules, utility requirements, and permitting steps — which is why having an experienced contractor matters from day one.

 

Prowork Contractors manages the entire ADU process: site evaluation, design, permitting, and construction, so your finished unit is fully code-compliant and built to the same standard as the rest of your home.
