How to add ADUs to your Comparable Properties
Use this tutorial when a comparable property has an accessory dwelling unit that needs to be represented in the Sales Comparison Approach.
Before you begin
Before you begin, open the URAR report. Gather MLS data, public records, photos, remarks, or other support for the comparable ADU. Confirm whether the ADU is inside a dwelling or in an outbuilding.
Confirm whether it is a standalone ADU, ADU/garage, or another ADU configuration. Confirm the subject ADU structure first if the subject has an ADU. Do not count an ADU as a regular non-ADU unit.
Open Sales Comparison Approach
Use the left navigation to open Sales Comparison Approach. Locate the comparable property. Confirm the comparable address and sale data are correct.
Review the subject ADU rows for comparison context.
Add the ADU to the comparable
Open the comparable add/options menu. Choose the ADU-related unit option if the ADU is part of a dwelling. Choose the standalone ADU or ADU/garage outbuilding option if the ADU is in a separate structure.
Add the ADU row or structure. Confirm the row is identified as an ADU. Avoid adding the same ADU in both unit and outbuilding areas.
Complete ADU details
Complete ADU location information. Complete ADU room details. Complete living area or area fields.
Complete quality and condition. Complete heating, cooling, and utility details where required. Add data-source support in commentary if needed.
Add comparable photos or exhibits if they support the ADU.
Compare and adjust
Compare the comparable ADU to the subject ADU. Compare ADU presence if the subject does not have an ADU. Enter an adjustment only when supported by market evidence.
Add commentary for the adjustment or lack of adjustment. Confirm the ADU data is consistent with comparable remarks and public data.
Validate
Run validation. Resolve ADU-related errors first. Confirm ADU rows are not duplicated.
Confirm ADU counts are consistent. Save the Sales Comparison Approach section. Re-run validation after corrections.
