Living at 8th and Fulton (next to Golden Gate Park), how difficult is it to find street parking?

It will probably be nowhere near as bad as if you lived in North Beach or Castro where even with a parking permit finding a place after 6 pm on a weekend is near impossible. You may have hunt for a place and hike a coupl of blocks but the farther west you go the easier it should be.

My main concerns would be:

1. Forgetting about street cleaning day and getting tickets (you mentioned you don't drive too much).
2. Having your car burglarized.

According to it,in the last 6 months there have been 184 car break ins and thefts in the Inner Richmond neighborhood in the last 6 months. So there is a good chance you will have your car broken into if you leave anything in it that would attract theft. (Also, hopefully you don't drive a really nice car--if you do consider a garage.)

Anyway, good luck. I am sure it will probably be fine.
