I'm having to talk to my now retired and elderly mother about her spending habits and how unreasonable it is that she doesn't want to give up even an inch of her lifestyle even though it could leave her broke and hurting in the end.

Occupiable spaces, habit- able spaces and corridors shall have a ceiling height of not less than 7 feet 6 inches (2286 mm).

Now it’s inching up to $400.

They have a 3.5x5 inch option.  

Again, you’re going to need binders (I always use white binders) that are 2 inches thick this time, not 3 inches like the ones you used for the mail system.

It appears it was installed without the 18 inch minimum straight run of piping.

I took some satisfaction out of the fact that the little guy was pushing a boy's bicycle with 20-inch wheels up a hill, obviously really going places in his miserable life.

We had mostly brick homes, but we did have some houses that just had siding and we spent many times digging out bullets just over the babies crib, in the wall inches from the TV set, and more.  

Building code may be an issue, if your area requires a fire wall between living units, that means a fire resistant wall (block) that raises above the top plate about 18 inches I believe under roof, that would be hard to put into an existing building from the foundation up.By the time you do a conversion I'd say your tenant would be paying the cost of the add ons, you'll be paying for the house.

Your house floor may be supported by 12 inch to 18 inch brick or concrete pylons.
