This hardware store features at least 3 times in the game, but I'm pretty sure I've seen more of them, just can't remember where at the moment.
The Paleto Bay & Chumash stores are almost an exact copy. The Route 68 paint shop has been modified a fair bit, but you can still tell it's modelled on the real life building.
I believe the timber building/storeroom on the right is also based on the one in real life, but it has also been modified a bit.
It seems like R* have used 1 or 2 buildings from lots of different towns around California. That makes it hard for us to find them all though.
Real life. Fulkerson Hardware at 3403 Somis Rd, Somis CA.
In game. (1) Bay Hardware in Paleto Bay. (2) The Paint Shop on Route 68 in Great Chaparral. (3) Hardware store in Chumash Plaza.
