I didn’t feel good about a recent deck I inspected. The deck ledger was fastened to the house using nail, big no no. Also, the joist did not rest on any post but were attached to the post to beam connection via fasteners. I know you can use joist fasteners at the ledger board, but is it okay to secure the other end of the joist to the post to beam connection via joist hanger? My gut tells me no. The owner (my Aunt, this was a mock inspection) said the deck was built that way when they bought the home brand new 13 years ago. One picture shows the ledger board as secured to the house with nails and supporting the joist with fasteners. The other photo shows the other end of the joist where it attached to the post to beam connection. I should note the post to beam connection had a horizontal crack running the course of the beam as well.
