Notice the posts farthest from the house (4x4s). The 2 posts closest to the house were 2x4s, not anchored to the house and just sitting on top of the ground. You could actually swing them around, so the deck was holding the post up.
I didn’t walk on that deck, but the pest control guy did–he got on it from inside the house without looking at it carefully outside first. Could have been a big mistake (he’s a hefty guy).
Your deck support posts rank right up there with the electric issue I saw yesterday.
There were two j-boxes wired on the exterior of home, so the window units could be plugged in (I know, only little city, America). After Seller had the electricity turned off, he went back and removed the two outlet receptacles from the j-boxes on the outside.
To make a long scare short, in one box he left the 3 conductors sticking out in mid air - so they wouldn’t touch. No cap, no tape, and the breaker was on.
The other box he clipped the conductor and shoved it back inside the metal j-box, breaker on here, too.
Makes a person realize not everyone has common sense.
Not a problem down south but those concrete support blocks for posts are banned here now unless the deck/patio is less than 2’ high and not attched to the house. All others must be built on concrete piers or preservative treated posts with the base at least 4’ in the ground.
