we are back with michael pappus, the executive director of the san fransisco interfaith council and the council has taken up a big, critical issue and that is the issue of providing affordable housing for essential workers here in san fransisco. and as you were saying, congregations have land or they might have underutilized property that might be able to be used to help provide housing for these essential workers. but the question is, how? what's a housing trust? >> well, first and foremost, i think what you're going to see in san fransisco more and more is the repurposing of properties because there certainly is also a benefit to the congregations themselves when they can have a worship space on the first floor and then housing up above. you will see a mutual benefit there. what is important is that, that we look at these properties as opportunities to provide that housing. >> m-hmm. >> we worked with the university of san fransisco's leo tim mccarthy society to do a mapping of all the properties in san fransisco and worked with the mayor's office of housing and office of workforce de
