Structure size address level data

Hi all, I'm a university student working ahead on a final project for one of my GIS classes this semester. I'm doing a review on housing development versus various census data in the San Francisco Bay Area. I'd like to find a way to have point level data for multifamily units or housing projects so I can compare it to census tract level ACS data. I figured if I could find any sort of address level data (addresses for housing projects for example) I could geocode it. Sorry if this is an obvious question, looking for any advice I can get on how to approach this. Thanks
