Checklist: move vegetation at least 3 feet from the foundation, deck, porch or siding; trim lower branches of trees to at least 6 to 10 feet. Example plants acceptable in the first 10 feet include columbine, violet, primrose and phlox.","asOf":"2026-08-25T00:00:00.000Z","object":{"kind":"guide","id":"what-tfs-rates-where","title":"What TFS rates where","url":"/guides/what-tfs-rates-where/"},"source":{"title":"Firewise Landscaping in Texas","url":"https://tfsweb.tamu.edu/wp-content/uploads/2024/05/EDITED202012firelandscape.pdf","publisher":"Texas A&M Forest Service","sourceType":"official","accessedOn":"2026-08-25T00:00:00.000Z","documentDate":"2012-10-08T00:00:00.000Z"}}],"local":[{"id":"guide:class-a-covering-not-a-bag:5","anchor":"local-us-tx-austin-class-a-covering-not-a-bag-5","place":"Austin WUIC (2024, local amendments)","placeId":"us-tx-austin","scopeKind":"place","scopeMode":"exact","scopeRef":null,"claim":"Austin WUIC 506.2 Exception 4 lets one- and two-family roofs steeper than 2:12 use a covering tested as Class A under ASTM E108 or UL 790 over a combustible deck with no less than 30-pound felt.
