i paid 60 a month for an out door parking hooded by the building i acutally lived in on 76th and south shore about 10 yrs ago. when i lived on 67th and south shore about 8 yrs ago i had secure parking
inside under the building which was 100/mo at the time. so i hope that helps you.
you know parking is a big deal in south shore , so good luck.
The parking rate will vary. I don't know of many security gate, outdoor parking areas. A lot of the parking in that type of lot is reserved for tenants. If you are looking to relocate into a particular area in South Shore, ask before you buy about the parking situation.
