Building an ADU in Encino, CA typically costs between $150,000 and $400,000 or more, depending on the type of unit, size, and level of finishes. A garage conversion is the most affordable option, generally ranging from $80,000 to $150,000, since the existing structure eliminates foundation and framing costs. A detached ADU built from the ground up on an Encino lot typically runs $200,000 to $400,000+, depending on square footage and design complexity. Attached ADUs fall somewhere in between.
Several factors affect the final cost: lot conditions, utility connections, architectural design, permit fees, and material selections. In Encino — where average home values exceed $1.5 million — a well-built ADU commonly adds $300,000 to $500,000 in property value, making the investment especially strong.
