SF Dept. of Building Inspections: " You must have one garage per unit."....SF DPW, Bureau of Street Use and Mapping: " Your driveway must be 35 degrees downslope."....

Joseph Heller, author of "CATCH TWENTY TWO",  should have lived in San Francisco..

If so, he could have written a sequel :  "Catch  Thirty Five"...

A friend of mine is building three flats, and had to insert a three car garage, even though the City's
"DPW Dept, in effect, said  "Your Driveway slope has to be  35 degrees, not the 31 degrees that you would have, if we let your driveway encroach 5 feet into the 22 foot wide sidewalk...

Now my friend has to eat  the big expense of an appeal to the Permit Appeals Board, or live with a useless driveway..

31.5 degrees

31.5 degrees

37 degrees

41 degrees, Bernal Heights.

Halfway from 30 to 40 degrees is what DPW  demands.
