Getting Started

There are many ways to create accessory dwelling units (ADU) or junior accessory dwelling units (JADU) on your property. Following is an overview of the terms the Town of Truckee uses to describe ADUs and JADUs.

Attached ADU

An attached ADU is within or directly connected to an existing or proposed primary dwelling or its attached garage, having a wall and/or other conditioned space in common. This can include remodeling an existing permitted living space into an ADU, converting existing non-living space into an ADU, adding square footage or an additional floor to the primary dwelling or its attached garage to create an ADU, etc.

Junior ADU (JADU)

A JADU is a smaller type of attached dwelling unit that is no more than 500 square feet in size

Detached ADU

A detached ADU is physically separated from an existing or proposed primary dwelling and its attached garage, not sharing a common wall or other conditioned space. This includes converting an existing detached structure into an ADU, adding square footage or an additional floor to an existing detached structure to create an ADU, constructing a new detached structure to create an ADU, etc.
