Building an Accessory Dwelling Unit (ADU) has become one of the most popular ways for Los Angeles homeowners to increase property value, create rental income, or house family members. Whether you’re planning to convert your garage, add a backyard suite, or build a detached unit, understanding the process is crucial.
Partnering with trusted professionals like My Home Builders, Inc., one of the leading adu contractors ensures that your project meets local regulations, stays on schedule, and results in a space you’ll love for years to come.
This detailed guide explains everything you need to know about building an ADU in Los Angeles, from planning and permits to construction and design tips.
What Is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary housing structure built on the same lot as an existing single-family home. ADUs come in several forms:
- Detached ADU: A separate building on your property, such as a backyard cottage or small guest house.
- Attached ADU: An addition that connects to your main home.
- Garage Conversion: Turning an existing garage into a livable space.
- Basement ADU: Transforming an underutilized basement into a fully functional apartment.
California’s relaxed zoning laws have made ADUs easier to build, allowing homeowners to add affordable, flexible housing to their property.
Why Build an ADU in Los Angeles?
Los Angeles faces one of the toughest housing shortages in the country. ADUs provide an affordable, efficient way to add living space without buying new land.
Key Benefits:
- Extra income: Rent your ADU to offset mortgage costs.
- Family housing: Create private living space for relatives or aging parents.
- Property value: Homes with ADUs often sell for more in Los Angeles’ competitive real estate market.
- Sustainability: Smaller, efficient units reduce energy consumption and urban sprawl.
When you work with experienced adu contractors in Los Angeles, you can take full advantage of these benefits while avoiding costly design or permit errors.
Understanding ADU Regulations in Los Angeles
Before construction begins, it’s essential to understand the city’s ADU requirements. Los Angeles follows both state and local guidelines that determine where and how you can build.
Key ADU Rules:
- Lot Size: Most residential lots qualify for an ADU. Minimum size requirements have been eased.
- Setbacks: Detached ADUs must be at least 4 feet from side and rear property lines.
- Parking: In most cases, no new parking is required if your property is within half a mile of public transit.
- Height Limits: Detached ADUs can reach up to 16 feet in most zones; multi-story designs may vary.
- Owner Occupancy: Recent laws allow homeowners to rent both primary and secondary units.
Because ADU laws evolve frequently, working with skilled adu contractors ensures your design complies with the latest updates from the Los Angeles Department of Building and Safety (LADBS).
The Step-by-Step Process of Building an ADU
Building an ADU involves a structured process from planning to completion. It includes site evaluation, design, permits, construction, and final inspection to ensure full compliance.
Step 1: Site Evaluation and Feasibility
Every successful ADU project begins with a site evaluation. Professionals from My Home Builders, Inc. assess your property layout, utility connections, and zoning regulations.
During this phase, you’ll learn what type of ADU your property can accommodate and receive initial design recommendations from expert adu builders near me who understand Los Angeles property codes.
Step 2: Design and Architectural Planning
The design stage shapes how your ADU will look and function. Architects and designers develop detailed plans that align with your goals, budget, and city requirements.
Popular Los Angeles ADU design styles include:
- Modern minimalism: Clean lines and open layouts.
- Spanish revival: Stucco walls, tiled roofs, and archways.
- Contemporary backyard cottages: Efficient, stylish, and energy-friendly designs.
A professional adu contractor helps you select materials and finishes that balance beauty with long-term durability.
Step 3: Permit Application and Approval
Navigating Los Angeles’ ADU permitting process can be complex. However, California’s pro-ADU laws have made it much simpler in recent years.
Here’s what’s typically required:
- Site plans and blueprints prepared by a licensed architect.
- Structural and energy calculations that comply with Title 24 standards.
- Permit submission to LADBS or the local building department.
An experienced adu contractor in Los Angeles can handle these submissions on your behalf, ensuring faster approval and compliance.
Step 4: Construction Phase
Once permits are approved, construction can begin. This is where the expertise of seasoned adu contractors truly matters.
Construction includes:
- Site preparation and foundation work
- Framing, roofing, and insulation installation
- Plumbing, electrical, and HVAC systems
- Interior finishes and final inspections
Efficient project management ensures the process stays on schedule and within budget. Reliable contractors keep you informed throughout each phase, addressing any challenges quickly.
Step 5: Final Inspection and Handover
Before your ADU is officially complete, the city will conduct a final inspection to confirm that all work meets safety and building standards.
Once approved, you’ll receive a Certificate of Occupancy, allowing you to rent or occupy the new unit legally. This final stage represents the successful completion of months of careful planning and construction.
Types of ADUs You Can Build in Los Angeles
Different properties call for different ADU solutions. The type you choose depends on available space, budget, and intended use.
1. Detached ADU
Perfect for homeowners with large backyards. This unit provides full independence and privacy, ideal for guests or rental purposes.
2. Attached ADU
Great for homeowners who want to extend their existing living space without building a new structure.
3. Garage Conversion
One of the most popular options in Los Angeles. Transforming a garage into a studio or one-bedroom unit is efficient and cost-effective.
4. Junior ADU (JADU)
Smaller units, typically up to 500 square feet, created within the primary residence.
Each option has specific design and permit requirements, so partnering with licensed adu contractors los angeles is the best way to ensure success.

How Long Does It Take to Build an ADU?
The timeline depends on your project’s complexity:

On average, most ADUs in Los Angeles take 6–12 months from concept to completion. Working with knowledgeable adu contractors ensures the process stays smooth and efficient.
ADU Cost Considerations
ADU pricing varies depending on size, materials, and site conditions. Garage conversions are typically more affordable, while detached ADUs require more extensive construction.
Although costs can range widely, investing in a professionally built ADU often yields a strong return on investment (ROI) through rental income or increased property value.
Financing Options for ADU Projects
Homeowners have several ways to finance their ADU construction:
- Home equity loans or HELOCs
