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.
In most Los Angeles areas, especially those near public transit, current California law (SB 9 and ADU mandates) eliminates the requirement to replace covered parking when converting an existing garage. This makes the process much more affordable and feasible for most homeowners.
Yes! State laws encourage ADUs for rental housing. You can rent it out long-term to generate passive income immediately.
In Los Angeles, the permitting process usually takes 2 to 4 months, depending on the city’s backlog. Once permits are issued, construction takes another 3–4 months.
While your property taxes will be reassessed based on the value of the new improvements, your primary home’s tax base remains protected. Under Proposition 13, only the value of the new ADU is added to your tax bill, not the entire property’s market value.
Absolutely. We are a full-service design-build company. This means we handle the entire process, including architectural drawings, engineering, and navigating the Los Angeles Department of Building and Safety (LADBS) to secure all necessary permits for your ADU or remodel.
