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.

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:

Types of Accessory Dwelling Units

Attached ADU

These additions adjoin the primary home – to the side or rear of the home, or constructed on top of an attached garage.

Detached ADU

A stand-alone structure separate from the primary home. A detached ADU can be built as entirely separate unit or constructed over an existing accessory structure, such as a detached garage.

Garage Conversion ADU

Convert your garage into living space – can be one of the quickest and most affordable ways to add usable space to a home.

Junior ADU (JADU)

Built by converting an existing part of your home. e.g. a spare bedroom or attached garage. JADUs function as a regular ADU but do not exceed 500 sq.ft.
