For big structural changes, things like moving walls and redoing the floor plan, you'll need an architect to draw up plans to make sure that everything is safe and up to code.  

A door that is binding on the top is a sign that walls and floors are moving around.

@Faraad Mohamed  I tend to always use Kelly Moore "Wise Owl" mixed down to 50% in an Eggshell finish for the walls, and just Behr flat ceiling paint because it looks good and is cheap.

(see pic) The next door neighbor has been asking us to remove the tree as it is about 3-4 feet away from their wall and they are worried the wide spreading root will damage the house foundation and piping.

@Brit HaleYou can use a vertical PTAC for this-made by GE, does heat and cool but must be installed on an exterior wall.

If we remove a wall from the closet to make an entrance into the bathroom, it would give a little more space in front of the tub, but you lose 4' or so of closet wall space.

A basement may be used for habitable rooms or a dwelling unit, regardless of the depth of the floor below grade, if the floors and walls are impervious to leakage of underground and surface water and are protected from dampness, and if the required minimum 13-172-130, or by other approved means. 13-172-070 Natural light.

The subfloor and some joists were a little warped because of poor ventilation and oddly heavy furniture (previous tenant had installed a lot of gym equipment and climbing walls), which made aligning some of the planks tricky but not overly difficult.

The basement needed a big change, the walls were dark and it didn't feel like home.

But the policy documents list us, the owners, as occupants and instead of just coverage from the walls in, essentially, also cover our personal property, as if we lived there.
