The safety of stairs is directly related to how the occupant uses them, so the safety features related to stairs in the building codes are also related to the user.

There is no generic 2-ft. rule. Use the code tables to dial in joist spans and overhangs based on accurate engineering.

The code requires installing an approved material to slow the spread of fire between floors and adjacent vertical and horizontal cavities — here are the allowed materials and required locations.

Get the specifications you need to install stairs, porches, decks, and more to provide a safe, comfortable means of egress that meets building codes.

By considering things like energy-efficient mechanicals, window orientation, and renewable energy sources, homes can be evaluated to meet the energy codes. Here's what the IRC has to say.

Whether you calculate maximum assembly U-factors or insulation minimum R-values, there is more than one way to reach the IRC's energy-efficiency requirements.

Learn about the minimum size requirements for homes according to the IRC, including habitable rooms, hallways, and ceiling heights.

Learn about the essential building code requirements for garages to ensure safety and prevent fire hazards.

Learn how the IRC addresses ways to prevent the spread of fire from one property to another.

Be it structural collapse, fire, or disease caused by water contamination or unsanitary waste disposal, the origin of building and health codes often can be traced to human tragedy.
