renting artist space in the city

My lease is up in 4 months, and just wanted to know what the scene is like for renting a live/work space in SF. I dont really see much, but i dont really know where to look. I have a car so obviously i wont be looking for a space on market street or something like that. I need to live there but have an open space for my studio. I dont really play music super loud. not like a live band would. Any ideas where i should be looking?
