Attached guest unit: GLA?

[samc6782]

From the sounds of your situation, I would tend to agree with CAN, but, it's up to you to determine. I, personally have a similar situation these past couple of days.

I went with CAN and others' suggestion. It's annoying because home builders and agents all like to include this both as GLA and an amenity (at least in SoCal) when talking up properties, so the owner is invariably a bit annoyed that they don't get to have their cake and eat it too. Which is not my problem if I do the right things and support what I do, but still.

But to what you're saying above, I'm sure many would agree: it's up to me to determine using how the market reacts, and in my situation, the market would most likely consider that GLA an attached guest unit amenity. But there was someone recently who made a worried post about what was likely to happen to him after having included a detached guest unit as GLA and getting called on it. That's "wrong," but it sounds like that appraiser determined that it made sense to include it as GLA when doing the report. I don't think anyone advised that poster to double down and try to explain how he determined he should include the GLA.

So regardless of what you determine, at least in my market, there are still some "rules" about this you have to follow. Detached guest unit: definitely not GLA. Attached guest unit with no interior access: not GLA. Attached guest unit with interior access and a mini kitchen....? Attached guest unit with interior access and no kitchen: definitely GLA. Attached guest unit with interior access only via little used elevator: probably not GLA...
