Container ADU: building an accessory dwelling unit in the backyard

An accessory dwelling unit, or ADU, is a small second home on the same lot as a main house. A container is one of the most efficient ways to build one, because it is quick to place and easy to finish.

Why a container ADU

• Fast to place on a prepared foundation.
• Compact footprint, which suits a backyard.
• Can be moved or extended later.

Check the rules

Many cities cap the size of an ADU and set rules for height, setbacks and parking. Some require separate utility connections or a minimum lot size. Check with the planning office first.

Utilities

An ADU may need its own water, sewer or septic connection, and a separate electrical meter. Plan these early, because they often decide the site layout.

Rent or family

An ADU can be rented, or used by family members. Think about the entrance, privacy and a separate outdoor space.

Design the unit in the UnedPod configurator, and read the guide to zoning rules before you finalise the position.
