What are code requirements for bedrooms?
Monday, August 20, 2018
The building code seems to use the words “bedroom” and “sleeping room” interchangeably, with a sleeping room being simply a room used for sleeping, although neither words are included in the definitions section of the code. For example, both International Residential Code (IRC) and the Residential Edition of the Florida Building Code (FBC) state that a smoke alarm should be installed “in each sleeping room” and then, on the next line, specify that an alarm should also be installed “outside each sleeping area in the immediate vicinity of the bedrooms.”
Bedrooms must further comply with a minimum size requirements for any room defined as a “habitable room.” Here’s the International Residential Code (IRC) specs:
- Minimum area of 70 square feet (IRC R304.1)
- Minimum horizontal dimension of 7 feet (IRC R304.2)
- Minimum ceiling height of 7 feet. If a sloped ceiling then a minimum of 50% of ceiling must be minimum 7 feet (IRC 304.3).
- Must have an installed heating system capable of maintaining 68º F (IRC R303.10). A plug-in space heater or window unit does not count.
Some jurisdictions will have a higher standard for defining a habitable room. But the basic premise is simple: you can’t call a closet-size, unheated room a bedroom.
Then there are the multiple safety requirements for a bedroom or sleeping room that, once you consider that it is a place where people spend long hours unconscious and in the dark, make sense:
Each bedroom must have an egress window. Egress is “a way out,” and an egress window in the building code is defined as a required alternate route out of the home in an emergency, typically a fire. All sleeping rooms must have a window of adequate size opening for a person to get out and a rescue fireman with a backpack to get in. The minimum specifications in the International Residential Code (IRC R310.1) and Florida Building Code (FBC) are:
- Minimum width of window opening: 20 inches
- Minimum height of window opening: 24 inches
- Minimum square area of opening: 5.7 square feet (5.0 square feet for ground floor)
- Maximum window sill height: 44 inches
- Must be openable without keys, tools, or special knowledge.

Smoke alarms are required in each bedroom and adjoining access room (IRC 314.3). They must be interconnected, so that the activation of one alarm sets off them all.
Carbon monoxide alarms must be installed outside sleeping areas of residences with fossil-fuel appliances or with an attached garage (IRC 315.1). To find out more about carbon monoxide alarms, visit our blog Are carbon monoxide alarms required to be installed in homes in Florida? Also, the code does not allow does not allow a bedroom door to open directly into a garage due to carbon monoxide (IRC 302.5.1).
Requirements for egress windows, smoke and carbon monoxide alarms have been implemented over the last several decades and older houses are not required to meet the new bedroom safety standards unless certain types of remodeling or additions are done to the home. But if your are concerned about your family’s safety at home, upgrading to meet the current bedroom safety standards is a good idea.
