Nashville Home Inspection - Stair Step Dimensions - 9.13.10

By
Home Inspector with HABITEC Home and Building Inspections, LLC

Staircases seem to always be a part of Nashville Tennessee Home Inspections completed by HABITEC Home and Building Inspections, LLC.  In older homes staircases can present a problem when it comes to dimensions.  Look at the picture below.  Does this look OK?

HINT:  You are looking down the staircase leading to a basement in a house about 100 years old.

STEEP Basement Steps

The pic below is a closeup of the stairs while standing in front of the stairs in the basement.

Front View of Steps

ANSWER:  It is hard to know for sure without using a tape measure, but these stairs are very steep and therefore present a falling hazard.  Look at the pic below to see the measurement of the step rise.  Almost 9 inches!

Tall Step Rise

The pic below shows the step run, or horizontal measurement.  Less than 8"!

Short Step Run

Proper step rise and run dimensions are shown below in a drawing from Code Check.  Most municipalities use IRC numbers.  In this staircase, both dimensions are wrong.  If either measurement is inadequate the Client for the Home Inspection needs to know because this presents a safety hazard.  When both dimensions are wrong, this is a serious falling hazard.  So the answer is NO, this is not OK.

Stairs can be dangerous, not just for the steepness, but sometimes they are OLD and they break.  My brother broke a shoulder when a step on an old house broke as he was going down them.

Hello Matt.  Code Check is a great source for pictures like this.  I bought the CD version but they also come in paper format.

Hello Sarah.  I am sorry to hear your brother was injured by a broken step.  In any home, but surely in older homes built when the code was lacking, stair systems can be a common source of injury.  That is why at HABITEC Home and Building Inspections, LLC, we have little patience if these systems are compromised in any way.

Thank you,

Hi Kim: 73/4” in height with a variation of not greater than 3/4” is the norm. You would have to check in your community for their specific requirements. Rob-HABITEC Inspections
