Deck Safety Checklist | Fillable PDF for Homeowners and Contractors

Is your deck dangerous? Here’s a checklist so you can see for yourself.

Most deck failures don’t happen without warning. The signs are usually there: a loose guard post, a ledger pulling away from the house, rot at the base of a post. This checklist shows you where to look, what to look for, and how to record it.

Built by a carpenter with more than 40 years of deck-building experience, the Deck Safety Checklist walks you through a deck in the same order a professional would: house attachment first, then framing and footings, then the surface, guards and stairs. Each item has six clear ratings (No Issue, Monitor, Concern, Urgent, Not Visible, N/A), so you always know what you found and how serious it is.

GOOD TO KNOW

• This is a visual checklist for recording the apparent condition of a deck. It is not a home inspection, code inspection, engineering evaluation, permit, certification or warranty.
• It cannot see hidden defects inside framing, behind siding or below grade.
• Code values shown are typical U.S. model-code figures. Codes and licensing requirements vary by location, so confirm local rules with your building department.

If you are a layperson and see a serious hazard, stay off the deck and have it evaluated by us or another qualified professional.
