When should framing be installed above a window or door in relation to stucco application?

Installing the framing above a window or door before the sheathing and stucco application is crucial for a few reasons. First, it ensures that the framing is properly integrated with the overall structure of the wall, providing necessary support and stability for the openings. When framing is placed beforehand, it allows for proper alignment and spacing for both the sheathing and the stucco.

Additionally, this timing helps prevent potential issues with moisture infiltration. If the framing is done after the sheathing or stucco, it could create areas where moisture could become trapped, leading to wood rot or compromise in structural integrity. By completing the framing first, it allows the sheathing to thoroughly cover and protect the framing members, providing a solid, moisture-resistant barrier before the stucco is applied.

The other options do not reflect the best practice. For instance, installing framing after sheathing does not allow for proper embedding of the framing into the wall assembly and can complicate the installation, leading to potential structural or moisture-related issues. Similarly, installing it during the stucco application can hinder the stucco's adherence or protection, while stating it can be done at any time ignores the critical sequencing necessary for a robust and durable assembly.
