Ceiling Height in a Remodeled Basement:

There has been some controversy over the height(s) of the ceiling in a newly remodeled basement. With all of the obstacles located in the normal old home, a contractor has to be innovative to meet the adopted code. Here are the facts out of the 2006 IRC:

CEILING HEIGHT. The clear vertical distance from the finished floor to the finished ceiling.

The required height shall be measured from the finish floor to the lowest projection from the ceiling.

1. Beams and girders spaced not less than 4 feet (1219 mm) on center may project not more than 6 inches (152 mm) below the required ceiling height.

2. Ceilings in basements without habitable spaces may project to within 6 feet, 8 inches (2032 mm) of the finished floor; and beams, girders, ducts or other obstructions may project to within 6 feet 4 inches (1931 mm) of the finished floor.

3. For rooms with sloped ceilings, at least 50 percent of the required floor area of the room must have a ceiling height of at least 7 feet (2134 mm) and no portion of the required floor area may have a ceiling height of less than 5 feet (1524 mm).

4. Bathrooms shall have a minimum ceiling height of 6 feet 8 inches (2036 mm) over the fixture and at the front clearance area for fixtures as shown in Figure R307.1. A shower or tub equipped with a showerhead shall have a minimum ceiling height of 6 feet 8 inches (2036 mm) above a minimum area 30 inches (762 mm) by 30 inches (762 mm) at the showerhead.

Letter to the State of Colorado (Joseph Montoya)

During our busy summer projects, I had the pleasure of working with the 3rd party inspectors at Colorado Code Consulting. It was a pleasure working their cooperative attitude and flexible schedules even if we required a last minute inspection on one of our projects. I am happy to recommend their team as professional hard working individuals.

 I participated in the CBO Technology Exam Review class you taught inQueen

Creek, AZ for the AZ Fire Marshal's Association last week.

 I had scheduled the exam for this morning and after having your class
worried that I had not scheduled enough study time. I have been in most of
the codes that are references on the exam fairly thoroughly the last year or
so, except the electrical and ANSI standard.
I took the test this morning and Passed. If not for the thoroughness of
your teaching I don't believe that would have been the case. Thank you for
the good job. I know that anyone who dedicates some time to studying the
sections you emphasize in your presentation will have no problem passing and
That was not the first class I have attended that you were the instructor
and I knew I would receive excellent quality teaching.
Thank you.
