@eternalvictory00 Congrats! I also adopted an adult dog (1y4m) and live in an apartment. Apparently I have a novel for you so sorry if this is overkill! Just looking to help and provide insight from someone who recently adopted a dog of the same age and lives in an apartment complex.
Is the dog in foster or a shelter? This will make a huge different in how much you know about the dog ahead of time. Dogs take a while to settle in, and you can't be sure of how potty trained, crate trained, or destructive he may be when unattended unless they've been in a foster home for a few months (and even then, sometimes they change). Our dog is luckily completely house trained, crate trained, and not destructive. However, he is dog reactive, quite fearful, and very defensive of his family. So we have our own set of challenges!
I would focus your first few days on reinforcing things you want, basically pay with food for every potty break to make sure he gets the point, and do some crate training to ensure that all potty accidents and inappropriate chewing are prevented once he's left alone. I'd suggest not leaving him loose and unattended for a few months while he settles in and you build good habits. Otherwise your schedule sounds great! That's what my dog gets, and he's a happy pup.
As for apartment living, know your contract rules and follow them At least in my complex, leaving poop and not leasing their dogs are common and drive me crazy. Just because everyone else is doing it, doesn't mean it's acceptable. Also, many people want to avoid on-leash greetings for various reasons, and it isn't actually a good way for dogs to meet each other, so I suggest working on loose leash walking and avoid others while on leash until your dog has his friends and you know how he feels about other dogs. Also, finding food puzzles, indoor training, and sniffy games to burn off energy inside are important tools to have in your pocket since you might not have a yard or lots of space to run around. Good luck! It's really not that bad, even for my defensive and reactive boy.
