Building an ADU
Accessory Dwelling Units can provide an easy source of rental income for homeowners and low-cost housing for renters. Aside from its financial benefits, many homeowners seek ADUs to expand their home for personal or professional use.
We'll help you identify if expansion makes sense for your home, and what legal and development factors to think about, including managing the entire construction process.
An Accessory Dwelling Unit is a unit that can be added to an existing single-family home. ADUs can be detached (a separate building), attached to or part of the primary residence, or a garage conversion. ADUs are independent rental units that have their own kitchens, bathrooms, living areas, and entrances.
Are you considering building an ADU but don’t know if you properly meet requirements and regulations? Are you unsure of which type of ADU will add the most value to your existing property? Despite easing regulations that make it possible to build expansions to your home, there are still many complexities to consider. We’re here to help guide you.
At EcoSmart Builders, we are committed to providing leading edge construction solutions for designing, engineering, and building accessory dwelling units (ADU).
What are accessory dwelling units?
Accessory dwelling units, or ADUs, are small add-on residential buildings that can be used for housing or a variety of home applications. These functional buildings can be attached to the single-family home at ground level or constructed above a garage, or detached as a separate backyard ADU unit. Not only do they add value to the existing property, they can also provide additional revenue as a rental. They are becoming increasingly popular in Los Angeles County due to the short supply of affordable housing, and they offer an excellent opportunity for supplementary income.
EcoSmart Builders is one of the leading developers of sustainable accessory dwelling units in LA County. Whether you’re considering adding an extra housing unit, a home office, a home gym, or any additional space to your residence, EcoSmart Builders has the architectural and construction expertise to deliver exceptional results regardless of project scope. Here is what we offer:

Building an ADU on your lot
You are permitted up to two ADUs on a single family zoned property. If you are considering two ADUs on your property, it is restricted to one full Accessory Dwelling Unit (ADU) and one Junior Accessory Dwelling Unit (JADU).
How big can I make an ADU?
There are some limits on the size of an ADU, based on the size of your lot and existing house. First, an attached ADU cannot be bigger than 50% of the existing house. For example, if your existing house in 2,000 sq. ft., the attached ADU cannot exceed 1,000 sq. ft. in size. Second, there is a “mansionization ordinance” that usually restricts the total square footage of all structures on a lot to 45% of total lot size. For example, if your lot is 10,000 sq. ft., the total built area (existing house, ADU, garage, etc.) cannot exceed 4,500 sq. ft. In addition, most ADUs cannot exceed 1200 sq. ft. The Dept. of City Planning will need to verify the specifics related to your project. You can build a detached ADU up to 800 sq. ft. and 16′ tall without any local discretionary approvals. ADUs created by conversions are also granted automatic approval.
My lot is small or unusual. Can I still build?
Almost every lot in LA is unique, so we’re addressing the most common conditions. There are various types of ADU that work on different lots. For example, if a detached ADU will not fit in your backyard, you might attach a new unit to your current house. If the garage behind your house is inconveniently located, you could demolish and rebuild it with an ADU above.
