What is ADU?
An Accessory Dwelling Unit (ADU) is a secondary residential unit on a single-family or multi-family property. ADUs offer independent living spaces with their own kitchen, bathroom, and entrance, making them ideal for rental income, guest accommodations, or additional family living space. It’s not a surprise that ADUs have become so popular and maybe you have seen here and there your neighbours starting construction and seeing new neighbours coming in. This is not only a good source for monthly extra income, but also it just adds a lot of value to your property, in case you decide to buy a new house or rent it out in the future.

Before to start your project consider the type of the ADU you want and can build.
Attached ADU
An attached ADU is an extension of the main home, sharing at least one wall with the existing property. This option is great if you don’t want to make too many exterior changes and keep your home’s design while providing a separate living space for tenants or family members. Typically, attached ADUs range from 400 to 1,200 sq. ft., with costs starting at $150,000 and going up to $350,000+, depending on size, finishes, and site conditions.
Detached ADU
A detached ADU is a stand-alone unit built in the backyard or on an unused portion of the property. If you have a big backyard, or your house is on a big lot, then this is a huge opportunity to build one or multiple detached ADUs, which, by the way, are being rented even more expensive than attached ADUs. This option offers maximum privacy and can be customized with modern amenities, it can be rented not only to one or 2 person renters, but to a family. Detached ADUs typically range from 400 to 1,200 sq. ft., with costs between $175,000 and $400,000+, depending on design complexity and material selection and finishes.
Garage Addition
A garage addition involves expanding an existing garage or just converting garage space to a functional and 1 bedroom or a studio living space. Whether you’re adding a second story above the garage or extending it to include extra rooms, this is a great way to increase usable square footage. Garage additions typically add 200 to 600 sq. ft., with costs ranging from $80,000 to $250,000+, based on the scope of work and structural modifications.

Room Addition
When families grow, the housing needs grow as well and not always you can afford buying a new house or you just don’t want to leave your home. So a room addition is a cost-effective way to expand your home. Whether you need a new bedroom, home office, or family room, our team ensures a seamless blend with your existing structure. Room additions typically range from 200 to 600 sq. ft., with costs between $75,000 and $200,000, depending on design and structural changes required.
Second Story Addition
A second-story addition is perfect for homeowners who want to double their living space without sacrificing yard area, especially in areas of Los Angeles where houses are two story so adding the new level will bring more money value to the house. However, this is a major renovation that requires correct structural planning, and choosing the right general contractor is very important. Our team has the skills to execute these kinds of projects flawlessly. Second-story additions generally range from 500 to 1,500 sq. ft., with costs starting at $200,000 and exceeding $500,000, based on square footage and construction complexity.

Understanding Los Angeles ADU Regulations
No one wants to get stuck in the construction process, therefore, navigating Los Angeles ADU regulations is crucial to ensure compliance and avoid costly mistakes. We follow and know local laws and procedures and handle the permitting process for a smooth construction experience.
Key ADU Regulations
Zoning Requirements
ADUs are allowed in most residentially zoned properties in Los Angeles. Some neighborhoods may have specific zoning restrictions, so it’s important to verify with city planning authorities.
Minimum
Lot Size
There is no strict minimum lot size for ADUs in Los Angeles, but property owners must ensure sufficient space to accommodate setbacks and access points.
Setback and Height Restrictions
ADUs must be set back at least 4 feet from property lines. Height restrictions vary, but detached ADUs are typically limited to 16 feet. Second-story ADUs may require additional approvals.
Parking Requirements
No additional parking is required if the ADU is located within a half-mile of public transit.
If parking is required, it can typically be accommodated through tandem parking in a driveway.
Building
Codes
All ADUs must comply with California building codes, including requirements for energy efficiency, structural integrity, and fire safety.
Permitting Process
Obtaining permits is essential for legal ADU construction. Our team manages the entire process, from architectural plans to city approvals and inspections.
Owner-Occupancy Requirement
As of recent updates, Los Angeles does not require owner-occupancy for ADU rentals until at least 2025, making ADUs an excellent investment for rental income.
