Sunroom – Patio – Canopy – Pergola Shed Concrete Footing Foundation Slab Generic Plan

This plan provides a code-minimum design for footing and slab of various standard configurations for exterior lightweight non-habitable patios.  For use with open-walled patios, screen rooms, canopies, pergolas & enclosed sunrooms where UPLIFT is assumed to govern. NOTE: Not applicable where frost line requires increased footing depth. (Former Plan #20-23973)

The plan footings covered include slabs with continuous footings, ribbon footings with and without slabs, and concrete pads for a variety of wind speeds, exposures, and patio use throughout the US. It is sold as an engineered sealed document and meets the structural requirements of the 2020/2023 Florida Building Code and the 2018/2021 International Building Codes, as well as the current versions of the MN, NC, NJ, NY, OH, SC, & VA building codes as applicable.

Valid for use with ASCE 7-16 & ASCE 7-22. Use it in conjunction with your other approved documents to obtain a building permit. It is generic, and installations beyond the scope and limitations of this document shall require site-specific engineering.
