Installers Typically Do Not Provide Trickle Vents

Installers Often Do Not Pull Permits


Besides being a legal requirement, pulling a permit for a window replacement project has 

While pulling a permit does not ensure a code compliant installation, it certainly requires the installer to demonstrate an understanding and intent to meet code requirements.

So…How Do Associations Avoid This Nightmare? The following Best Practices are a good place to start:


 Windows should be the association’s responsibility, NOT the individual owners (but always check your governing documents). This policy protects the association from potential liability of the building enclosure being compromised by individual owners’ contractors.


 Require prior approval for ANY penetrations through the building enclosure. Similar to a permit application, the review process will not ensure compliance, but does force the contractor to communicate the details of the proposed installation. It also provides an opportunity for a building enclosure professional to review the proposed installation and make recommendations as applicable.
