So if no warmup, straight from parking lot to first tee, probably hitting my first shot 30 minutes or slightly longer after walking out the house.
Normally I'll do a brief (5-6min) warmup which makes it around 35-40 minutes, door to tee shot.
If I'm going to eat lunch before teeing off I allow a full hour.
Some of the guys I play with have been there a full hour before I arrive...hitting balls, chipping, putting, shooting the breeze. Not my thing. I'm fine with hanging around to socialize after golf but when I get to the course I'm like, "Let's goooooo!".
Like most answers...it varies on warm up or not. It is a 13 minute drive. About 5 minutes to get out of the car, set up the cart, put on the bag, throw in some water and gatorade, change shoes, get out a glove, ball marker, and divot tool. About a 30-60 second walk to the clubhouse to poke my head in the door to announce I am checking in. If no warm up, it is about another 30 seconds to walk to the first tee. So in total, about 20 minutes. If there is a warm up, add in another 15-25 minutes. A warm up is nice but if the tee box is open and me and the crew are ready to rock, we head straight over.
Live on course, and if I take Cart, about 2 minutes (Can leave development, and drive straingt down 1 (backwards), and if I take the car, about 4 minutes...
