Ever wished you could ask a building code expert a specific question and get an instant, accurate answer with the exact code reference? CodePro’s AI-powered app does just that—state-specific, fast, reliable, and always in your pocket.

Key Requirement: The maximum span for a 2x6 floor joist depends on several factors, including the spacing between joists, the wood species, and the load it supports. For a typical residential application with 16" spacing and a live load of 40 psf, a 2x6 can span up to approximately 9 feet.

Reason: The span is determined to ensure that the joist can safely carry the load without excessive deflection or failure over time.

Potential Pitfalls: Using the wrong spacing, wood type, or underestimating the live load can result in sagging or even structural failure. Always verify load requirements before installation.

Code Reference: 2021 IRC, Table R502.3.1(2)

What is the maximum floor joist span for 2×6?
What are the garage door requirements?

Key Requirement: According to the 2021 IRC, Section R302.5.1, doors between a garage and a residence must be equipped with certain fire-protection features. These doors should be:

- Solid wood doors not less than 1-3/8 inches in thickness.

- Solid or honeycomb-core steel doors not less than 1-3/8 inches in thickness.

- 20-minute fire-rated doors.

However, Utah Amendment (21) deletes the last sentence of IRC Section R302.5.1, which removes the requirement for these doors to have a self-closing or automatic-closing device.
