GBA vs GLA Measuring

[Ray Miller]

You measure the outside of the home that is the what I would call the GBA, yet in the 1004 it calls for the Gross living area. Is there a difference?

How do you report that difference between the sketch of the GBA and the GLA or do you or should you?

Do you take off unheated enclosed porches, 3 seasons room, garages from the GBA or do you sketch your heated areas and then add your unheated?

What kind of adjustments to you give for your unheated areas?

The 1004 does not ask for the GBA, only the GLA. GBA, in residential work, is usually referring to 2-4 units.

In a single unit building, it is possible for the GLA to equal the GBA.

What kind of assignment are you working on Ray? The 2/4 form deals with GBA instead of GLA. This is because many times units are located on the basement level. In this circumstance the GBA will include the basement square footage. Is your assignment a 2/4?

GLA refers only to above grade, fully finished living area. GBA, in the the context of a residential 2-4 unit appraisal includes GLA plus the area of the basement but does not include such things as porches, garages, carports, etc.

This is not an assigment. It is saturday afternoon thing because Rin Tin Tin and Sky King are not on TV anymore. So I have time to sit and think up these question that I see on the week days.

I see and have seen many 1004 reports where they measure the GBA leave off the unheated areas and the garage and call it GLA. I see some reports where they call it all GLA and have measured only the outside of the subject.

One of my old mentors only measured the outside, left off the porches and unheated areas and call it GLA.

Outside measurements of "above grade" living space (heated and finshed to a level comparable to the rest of the house) is GLA. GBA comes into play on the 1025 form. I just researched this yesterday (using the search function) and found what I needed. GBA is applicable to my assignment because the duplex and 2 comps are bi-level, with 1/2 the living area below grade. So reporting them as 750SF instead of 1500SF would be misleading and cause some funky adjustments.

Question and not trying to be a smart ***. Is the two comps bi-level duplex or single family? If they are single family can you use then for comparables on the 2 unit? What is your third comp?

The subject is a bi-level duplex. Two comps are also bi-level and one is a one story. The data shows rents vary with GBA and thus the value changes with the GBA. The one story has very similar area on the one level. I have not found a value differential for rentals having one story vs having stairs.
