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.
A custom build usually takes 9-12 months: 3-5 months for design and LADBS permits, and 6-7 months for construction and final inspections.
Not necessarily. We conduct a structural assessment to ensure your existing slab can support the new living space. If needed, we perform minor retrofitting or moisture barrier installation to meet modern California residential building codes.
ADU construction costs in Los Angeles vary based on the project type, square footage, and chosen finishes. At Kobzev Pro Contracting Group, we offer transparent, value-driven pricing to help you maximize your ROI:
- Garage to ADU Conversions: Pricing typically starts at $250 per sq. ft. Since we leverage your existing structure, this is the most cost-effective way to add a legal living unit to your property.
- New Ground-Up ADU Construction: For detached or attached units built from scratch, pricing starts at $300 per sq. ft. This covers complete site preparation, new foundation, framing, and full utility integration.
Please note: These are baseline investment figures for standard designs. Final pricing depends on your specific architectural choices, material selections (Standard vs. Luxury), LADBS permit fees, and the complexity of utility hookups. Contact us for a detailed, line-item estimate tailored to your lot.
While every project is unique, a standard Garage Conversion in Los Angeles typically takes 2 to 4 months for construction, once permits are issued. The permitting phase can take an additional 2–4 months depending on the city’s current backlog. We provide a detailed timeline before we start.
We trench new lines for sewer, water, and electricity directly to the main house or a separate meter. We manage all coordination with LADWP and the city.
