What is an ADU setback survey?

An ADU setback survey is a focused survey for homeowners adding an accessory dwelling unit. We locate your existing buildings and property lines in the field, then measure the distances between them so you can confirm the required setbacks. The result is a scaled plot plan that shows where a new or converted unit can sit on your lot.

Frequently asked questions

What is an ADU setback survey?

An ADU setback survey locates your existing structures and property lines and measures the distances between them, so you can confirm the required setbacks for a new or converted accessory dwelling unit.

Do I need one for an ADU permit?

Many jurisdictions ask for a scaled plot plan showing structures, property lines, and setback dimensions. An ADU setback survey provides the measured information your designer or plan checker needs to support a permit submittal.

How is it different from a full boundary survey?

An ADU setback survey focuses on locating structures and lines and measuring setbacks for a specific building project. A full boundary survey researches the deed and sets monuments at every legal corner, which is a broader scope.

How long does an ADU setback survey take?

Most single-lot projects involve a short field visit followed by drafting the plot plan. Timelines vary with lot size, access, and scheduling, but many are turned around within about one to two weeks.

What affects the cost?

Cost depends on lot size, the number of structures to locate, terrain and access, available records, and the level of detail your jurisdiction requires on the plot plan. Request a free estimate to scope your property.
