Los Angeles just made it easier to add an Accessory Dwelling Unit

(aka granny flat or guest house) in your backyard.

What is an ADU?

In general terms an ADU is a self-contained unit which contains all the necessities one needs to live such as a bedroom, kitchen, and bathroom. ADU units can range in square footage up to 1,200sq.ft. or 50% of the area of the primary residence per the California legislation. Some jurisdictions will have lower maximum square footage requirements. ADUs are typically single-story structures and can take one of five different forms, including:  detached unit, attached unit, repurposed space, inside of an existing home, garage apartment, or an above garage unit.

Financial Benefits of ADUs

The cost to build an ADU is substantially lower than alternative housing options because the land is already purchased and there typically is not a need for additional infrastructure or parking structures. The upfront financial investment required to construct a small backyard unit is much lower compared to the massive funding and endless rounds of capital raising for a large apartment complex.

Depending on the jurisdiction, property owners are typically permitted to rent out the ADU on their property for additional income. The rental rates will vary based on demand and location, but we have seen several instances where the rental rate earned from the ADU nearly covers the cost of the mortgage payment for the primary residence. This of course will vary on location and mortgage terms

How to Choose the Right ADU Design/Build Specialist

Designing and building an Accessory Dwelling Unit is a large, complex investment. You need someone who knows the ADU laws and has expertise in designing and installing smaller structures. We have spent the last decade installing hundreds of accessory structures throughout California. We know the ADU laws and what it takes to get them permitted and approved. We only use our own employees to design, assemble, and finish our structures.


Main Types of ADU's We Specialize In

Deciding whether you will be making an attached addition or conversion to your house or a separately built unit is critical to your planning. If you are considering remodeling your garage or adding a small guest house or granny flat,


There are two types of ADUs: standard accessory dwelling units and junior accessory dwelling units. Standard ADUs typically results in an increase in square footage of livable space. Junior ADUs are created from an existing part of the primary dwelling, such as a bedroom. These can take the form the following ADU styles:


Detached ADUs

Also sometimes called granny flat or guest house. It is separate from the primary home. Great solution for maintaining privacy for a rental unit

Attached ADU's

Attached ADU units are attached to the primary home. Flexible solution to expand the size of your residence or add a second unit for rent

Garage Conversions

Assessing  a garage for conversion to living space can be one of the quickest and most affordable ways to add an additional unit to a home. Usually used for rent.

Internal ADU's

Where part of the primary house besides is converted to an ADU. Allows extended families to be near one another while maintaining privacy.

When planning an ADU you need to take account for: parking requirements, setbacks requirements, height limitations, occupancy rules, city impact fees are just a few.

It's a lot to take and navigate through when you are trying to determine what type and size of an ADU your property can have.
