Known for its spacious lots, hillside terrain, and suburban character, West Hills presents unique opportunities for homeowners looking to add an Accessory Dwelling Unit (ADU) to their property. The larger lot sizes common in this area make it an ideal location for detached ADUs, garage conversions, and junior ADUs (JADUs).

Choosing the right contractor for your ADU project in West Hills can make a significant difference in both cost and outcome. Look for contractors who offer the following:
Adding an ADU to your West Hills property is a smart investment. Whether you're looking to generate rental income, house extended family members, or increase your home's resale value, a well-built ADU can deliver significant returns. With median home values in West Hills consistently above the LA average, the return on investment for a professionally built ADU is especially strong.
