Finding the Perfect ADU Construction Contractor: A Comprehensive Guide
Understanding ADUs and Their Growing Popularity
Accessory Dwelling Units (ADUs) have surged in popularity as homeowners seek to maximize property value, create rental income, or accommodate extended family. These secondary housing units—whether detached structures, garage conversions, or basement apartments—require specialized knowledge to build correctly.

A qualified ADU contractor should demonstrate thorough understanding of these regulations and help navigate the permitting process.
