Some
unfinished basements are better basement finishing candidates than others.
Here's how to evaluate your space for a basement finishing.
Basement finishing is a great way to add that
extra bedroom or playroom you've always wanted, if you have the money and
space.
Basement remodel cost
When it comes to basement finishing, not all
unfinished space is created equal. Consequently, the per-square-foot price of
basement finishing starts at $100/sq. ft. and can climb higher depending on how
much or how little remodeling you must do.
Granted, you won't have to dig and lay a foundation or frame and insulate exterior walls--that's already done.
Depending on your circumstances, here's what you'll need to know:

Building to code
The International Residential Code (IRC) says
a basement living space must have a clear, floor-to-ceiling height of at least
7 feet (6 feet for bathrooms). Local codes for basement finishing may vary, and
exceptions are made for the presence of exposed structural beams, girders, or
mechanical system components along the ceiling, but only if they're spaced at
least 4 feet apart and extend no more than 6 inches from the ceiling.
If your existing basement ceiling height doesn't meet those specifications, you have two options, and neither is cheap:
If your existing basement ceiling height doesn't meet those specifications, you have two options, and neither is cheap:
•Raise
your house and build up the foundation around it to gain the ceiling height you
need.
•Lower
the floor, which entails removing the existing concrete slab floor, excavating
to the desired level, and pouring new concrete footings and a floor slab.
Both options during basement finishing
require professional and precise engineering, excavation, and structural work
that will cost at least $20,000.
Add a staircase
The IRC also governs the staircase that leads
from your home's main level to the basement remodel. Requirements include a
handrail and stairs with proper width, tread, and riser dimensions. There must
be at least 6 ft. 8 inches of headroom at every point along the staircase.
If the stairway isn't wide enough (at least 36 inches) or the steps aren't to code, you may have to rebuild them during basement finishing, an extra cost of about $2,000.

Condition the space
Heating and cooling your basement finishing can
be as simple as tapping into existing HVAC main trunks and adding a couple of
vents ($1,000) or as complicated as upgrading your entire heating and cooling
systems ($7,000 to $15,000).
Your contractor will have to "size" your existing system to make sure it can handle the additional load and will comply with building codes that consider health and safety, such as adequate venting of furnace combustion gasses.

Cure moisture problems
You'll have to fix moisture problems before
basement finishing begins. You may have to waterproof walls and floors, grade
the yard so water falls away from the foundation, install a sump pump, or
install drains around the foundation, all or any of which can add thousands in
costs.
Add emergency egress
Code dictates that basement finishing have at
least one door or window big enough for people to get out and for help to get
in during an emergency: If you're including a bedroom, it must have its own
point of egress. Each egress opening must be at least 5.7 sq. ft. with the windowsill
no more than 44 inches above the floor.
Most basement walls are built using poured concrete or masonry blocks, which can be cut (although not as easily as wood-framed walls) to create openings for egress windows or doors.
