The primary concern when installing joists with notches and bored holes is structural integrity. Joists are critical components in the framing of a building, as they support the weight of the floor above and any load that may be placed on that floor.

When notches are cut into joists or when holes are bored through them, it impacts the joist's ability to carry loads effectively. Notching or drilling can weaken the joist by reducing its cross-sectional area and altering its load distribution characteristics. This can lead to potential failure under loads that the joist would normally support if left intact. Building codes often have specific guidelines for the maximum size and location of notches and holes to ensure that the structural integrity of the joist is maintained.

While issues such as cost, aesthetics, and ease of access may be relevant in the broader scope of construction and installation, they are secondary to the paramount importance of ensuring the safety and structural soundness of the building. Therefore, recognizing that maintaining structural integrity is essential in the installation process reinforces the importance of adhering to established practices regarding joist modifications.
