Can I replace our old Sunset swing doors with a modern roll-up?
Most neighbors already have. SF Planning's survey of the Sunset's Picturesque Period Revival tracts found most original double-hinged doors replaced with roll-ups while the recessed openings stayed, and its context statement says replacing an already-replaced door may not affect eligibility for listing. Keep the recess and the opening's shape, and choose a door whose design suits the house.
Can we put in one 16-foot garage door instead of two small ones?
Planning's Residential Design Guidelines lean the other way. They note that garage doors in most San Francisco neighborhoods are eight to twelve feet wide, and where a garage is too shallow for one small door, they prefer two doors of about eight feet separated by at least a foot over a single sixteen-foot door. Widening also involves the curb and Planning review.
Why can't the new door swing out like the old one?
If the garage sits at the front property line, an out-swinging or tilt-up door would open over the public sidewalk, and the California Building Code says doors and windows shall not open or project into the public right-of-way. A sectional or roll-up door that stays inside the line when open avoids the problem.
Does the door from our garage to the back stairs need to be a fire door?
It needs to meet the Residential Code's garage separation rule: solid wood or steel at least 1 3/8 inches thick, or a 20-minute fire-rated door, self-latching and fitted with a self-closing or automatic-closing device. A garage door may never open straight into a bedroom.
Can a San Francisco garage door have glass panels?
Yes, within limits. The Residential Design Guidelines allow glazing but want the door mostly opaque so parked cars are not visible from the street, with any other openings limited to required ventilation, set well below eye level and decoratively screened.
