With the changes, you will be able to build an ADU up to 40% of the square footage of the primary structure if it is attached i.e. garage.

What square footage?  

I bought a house with an illegally converted garage and they did not add the garage as square footage but I did get it lender financed.

hi,a tenant called us that someone went in to their apartment while they were not home (might be her boy friend but he denies it) and she wants us to check the cameras, and send the picture /videos to her,  so i have 2 questions1) is it 100% legal for me to send her any footage?

I will bet the attic rooms are not included.I would also encourage you to check the square footage, including what numbers the wholesaler has provided, what the property appraiser numbers are and then measure yourself with a tape measure.

if residential portion is 51% of square footage/income/ or 60% of value you can get conventional type rates, but not sold to GSE.

Or even splitting the heating costs according to square footage of the units?

I'm not sure you would get any benefit from 4BR vs. 3BR. with your square footage.  

This is for a duplex- total sq footage is 3200 sq feet.

If they're interested in selling, we gather the standard property information, such as the address, beds, baths, square footage, etc.
