What Counts as an Exterior Elevated Element?

EEEs include balconies, decks, porches, stairways, common-area walkways, and entry structures that extend beyond the exterior walls of the building, sit more than six feet above ground, and rely wholly or in part on wood or wood-based products for structural support.

The four scope tests

1. Projects beyond the building's exterior wall
2. Designed for human occupancy or use
3. Elevated more than 6 feet above adjacent grade
4. Load path includes wood or wood-based products

All four have to be true. Miss any one and the structure falls outside SB 721 — though local code may still apply.

What inspectors actually look at

• Load-bearing framing: joists, ledgers, posts, and their connections
• Fasteners and hardware, especially where corrosion accelerates
• Waterproofing membranes and deck coatings
• Flashing at the building envelope tie-in
• Guardrails and their attachment points

Common edge cases

Concrete balconies with wood guardrail posts still qualify — the wood is in the load path of the rail. Cantilevered steel balconies with wood decking usually don't, because the decking isn't structural. When in doubt, it's cheaper to have a licensed SB721 specialist look than to guess wrong.
