Stairs and Guardrails
Build stairs with consistent risers and treads, maintain headroom, and provide graspable handrails on at least one side where required. Landings must be level and sized correctly. Guards protect open sides that exceed required height thresholds, with baluster spacing that resists a four-inch sphere. Light the stair run and landings, and keep switches at top and bottom. Note local variations for exterior decks, and photograph attachments, post bases, and connectors before covering.
