The details below are minimum guidelines and are not guaranteed to be applicable.

All fasteners shall be galvanized or stainless steel for exterior applications.

All wall framing referenced in the details must be part of the home's main permitted bearing wall and/or lateral force resisting system.

Mounting equipment on fence walls (stand-alone walls of concrete, CMU or brick walls of any height), half walls, retaining walls, existing concrete pads, outdoor kitchen structures or sheds is not allowed. Supporting framing must be part of a permitted structure and any unusual framing near the mounting area that may compromise the wall's integrity shall be evaluated by the contractor and their licensed structural designer or other qualified person acceptable to the AHJ.
