   These are minimum
   ceiling joists to plate-3 8d.toe nails
   ceiling joists at laps 3-10d
   ceiling joists to parallel rafter 3-10d
   joists to rim joists 3-16d
   rafter to plate 2-16d toe nails

   Laps for joists IIRC are a minimum of 3", however that depends on whether they are being used to resist rafter thrust . I prefer on the order of 1' myself and always over nail them .

   These may not be current code so don't take my word alone on this. Been awhile since I actually had to deal with it.

   FWIW
   The info I listed came directly out of an old code book I had handy.
   It was CABO, table 602.3a

   It would vary depending on the span and pitch of the rafters.

   Shorter spans and higher pitches would require fewer nails. Longer spans and lower pitches would require more nails.

   .

   IMHO this is one of the downfalls of stick framing - No one ever bothers to check this stuff. They just keep building things the way they've always done it.

   We use 16d nails for framing. Three toe nailed into the plate, two on one side, one on the other. Joists are nipped on the top to match the rafter pitch, they sit completely on the plate. Two toe nails into the plate, three or four straight through the rafter, depending on size and overlap. Some high wind, seismic areas require metal straps or connectors in addition to the nails. 8d toe nails would not be acceptable for rafters or joists. Local codes vary.

   Beat it to fit / Paint it to match

   Thanks H. So 3 16ds into joist, 2 16ds into rafter, then 3-4 16ds into both joist and rafter.

   That's typically how we do it. With a 16d toe nail you can get a pretty good grab through a lot of meat. Placement of the nails should receive careful attention. You want to stay back from ends and edges so the wood doesn't split, avoid knots and watch wild grain. No sense adding extra nails if they will cause something to split. Two solid toe nails into a top plate is better than three that split the end.Beat it to fit / Paint it to match
