Stairs for a deck

The owner of this house in Ipswich asked me to design and build a set of stairs from the deck to the rear patio. We decided on a straight run as the best option for affordability and use of space. We began work a week ago and finished today, shown in the before and after photos below. I’ll return later in the summer to apply UV-protective solid stain to the pressure-treated wood, allowing it time to dry. Thanks to Tim Gillette for his assistance and workmanship!

Construction details:

  • Treads have a 7 7/16″ rise and 10″ run, with 1″ nose
  • The deck has 2″ x 6″ joists with a 2′ cantilever, so it was necessary to provide additional support for the upper end of the stairs with posts on Sonotubes.
  • We replaced the balusters on the deck railing, adding 4″ to bring it up to code.
  • The additional hand grip seen on the left is required on stairs.
  • All components are mechanically attached : joist hangers, ledgerlock bolts, trimhead stainless screws on risers, painted deck screws for treads.
  • Design and construction meet or exceed the 2009 International Building Code and the DCA-6 Prescriptive Deck Construction Guide.
New stairs, and new balusters on the deck.
