For a joist that is 10 inches deep, what is the maximum notch depth allowed (in inches)?

Explanation:
Notches in a joist are limited to a portion of the joist depth to maintain strength. The typical allowance is one-quarter of the joist depth. For a 10-inch-deep joist, that means the maximum notch depth is 2.5 inches. Going deeper would weaken the joist and would require reinforcement or an alternative framing solution. Smaller depths, like 2 inches, would still be within the limit, but they are not the maximum allowed.
