The Benefits of Custom Detached ADU Construction
PREMIUM BACKYARD HOMES
Building a detached ADU from the ground up offers the highest level of flexibility and property enhancement in the Los Angeles market. Unlike conversions or additions, a standalone backyard home allows for a completely independent structure with its own architectural character. This approach provides a blank canvas to design a living unit that perfectly meets your needs—whether it’s a high-end rental property, a private home office, or a luxury guest suite for family. By starting from scratch, we ensure every detail, from the new foundation to the custom roofline, is built to the highest modern standards of energy efficiency and structural longevity.
- Total Privacy and Independence: No shared walls or foundations mean the ultimate in acoustic privacy and independent living for your tenants or family members.
- Maximum Property Appreciation: Standalone units are premium assets that significantly boost your property’s appraisal value and overall market equity more than any other ADU type.
- Tailored Architectural Design: Designing from the ground up allows for a custom floor plan and exterior aesthetic that perfectly complements your primary residence and backyard layout.

Frequently Asked Questions
Planning an ADU, kitchen, or bathroom in LA? Get expert answers to start your project right.
A garage conversion to ADU in Encino typically takes 4 to 7 months from the initial consultation to final city inspection. The timeline breaks down into three main phases: design and planning (2 to 4 weeks), LADBS permit review (8 to 14 weeks), and construction (6 to 10 weeks depending on scope).
The permitting phase is usually the longest part of the process and is largely outside the contractor’s control — LADBS plan check timelines vary by project complexity and current workload. Kobzev Pro submits complete, accurate permit packages to minimize the risk of corrections that add weeks to the review. Once permits are issued, a typical garage conversion construction phase runs 6 to 10 weeks for a standard single-car garage conversion with a bathroom and kitchen.
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.
