At least for new dwellings, building without gas piping is _cheaper_ than building with it. It's very cheap to run additional 240V/60A lines from the load center to the kitchen and laundry/utility room.

Depending on the renovation, it can be even cheaper to go all-electric, for example, if the kitchen/laundry/heating is being moved.

However, renovations don't have much effect either way on the housing affordability crisis in San Francisco, because renovations don't generally increase housing capacity. Most renovations in SF are done for the purpose of converting existing lower end homes into higher end homes.
