To take full advantage of the affordable housing list for San Diego, I have added a link to different zip code maps for location purposes. There are many different maps and this will allow you to choose which one you would like to use in identifying the places in San Diego that you would be interested in from the affordable housing list of apartments.
There are also lists of other affordable communities that you would be able to identify due to the list being arranged by zip code and not name.
Be aware that there are waiting lists for most of the affordable apartments, so the sooner you apply the sooner you will find your new affordable home. Each apartment company is separate and so the application process would probably be related to the apartment housing interested in at the moment, needing new applications per apartment housing.
