Accessory Dwelling Unit (ADU)

If you’ve been thinking about increasing your existing livable space, you might have come across the term ADU or accessory dwelling unit. What is an ADU? An ADU is a living space secondary to a larger house on the same plot.

The popularity of accessory dwelling units has been increasing in Los Angeles and nearby areas over the past few years, meaning that a huge number of Americans are investing in real estate. By repurposing their own garages into ADUs, or building completely brand new ADUs from scratch in their backyard, they are able to have a guaranteed and regular income. A set of architectural and structural plans is required for building an ADU.

In many cases, ADUs are used as a living space for guests. Friends, parents, and relatives often live in these units. An ADU is not just a living space, an ADU can represent confidence, privacy, independence, and additional income. Obtaining the ADU architectural plans in California is relatively easy.

An ADU is subject to these statutory restrictions:

  1. Location
  2. Height
  3. Size

This information is contained in the Municipal Code of the City of Los Angeles. Professionals at Sten Engineering can prepare the set of structural and architectural plans for an ADU in Los Angeles. We will prepare all of the documentation required for obtaining the necessary permits and beginning construction.
