Should accessory dwellings be valued at the same price per square foot?
By Ryan Lundquist, February 4, 2025
Excerpts: Should accessory dwelling units be valued at the same price per square foot as the main house? This question came up recently, and many people believe the price per sq ft of the house should simply extend to the ADU. This post isn’t targeted at any one person, but I have a different perspective that I’d like to share.
Comps
When we look at comps with an ADU, do we see a value that resembles anywhere close to what the ADU equation above suggests? In other words, if the house was worth $800,000 and we added a 750 sq ft ADU, would that really add $200,000 in value? Or would a 400 sq ft ADU on a $450,000 house really add $163,640 in value?
What do the comps say? That’s the question we ask about solar panels, a kitchen remodel, a new driveway, or a house with an ADU. I find looking to the comps can sound like a very frustrating solution, but the focus is really simple. What are buyers willing to pay? That’s always the question.
Closing thoughts
I realize there are situations where the appraised value of an ADU legitimately comes in too low, and there is no excusing that. So, just as I recommend caution in using an arbitrary math formula, appraisers need to be careful to not just pick a number that doesn’t make any sense when we think about data and the income being produced by the ADU.
All I’m saying is the ideal is to scour comps, do our best to discover value, and support the value in whatever credible way we can. And my concern is if listings are priced without consideration of comps or data, it could result in properties not selling and/or appraisal issues in the future. Know what I’m saying?
