UAD and Acres vs Square Feet

When entering an area in the Site field on a UAD‑compliant appraisal, you'll need to know when to enter acreage (ac) vs. square feet (sf.) This doc will help you know when each unit should be used.

Regarding the Site field in the comparison grid, the UAD specifies the following:

  • Any site area less than one acre (43560 sf) will be expressed in square feet (sf) up to five digits with no decimals.
  • An area greater than one acre will be expressed as acres (ac) with up to 2 decimal places.

For example:

  • A site area of 44,400 sf would need to be entered as 1.02 ac.
  • A site area of .96 ac would be correctly entered as 41818 sf.

This means that some comps will have square footage and some will have acreage - in the same grid.

While WinTOTAL and TOTAL will convert the data in your report as you enter it, this chart might be a handy reference.
