I am working on some CMU houses that are going to be constructed with about 1" of separating between their "property line walls". The structures are totally separate except for measures taken to keep water from getting between the two walls. The builder would like to use a continuous footing...

I use the Wood Frame Construction Manual (WFCM) as a design resource when designing residential houses. My question pertains to the rafter span tables. How do these tables account for wind? There are some span tables that include a ground snow load but none that include wind loads. Thanks...
