>There is no rent control for single family homes anywhere in CA.

"Rent control is in effect for all San Francisco renters who reside in buildings constructed before June 1979. This means your rent can only increase by a governmentally mandated percentage each year, based on the cost of living index, and with a 30-day notice. If your landlord has improved the facilities in your building, he can petition for an additional increase, but the Rent Board must approve his request, which can't exceed 10 percent. If a landlord is negligent in his maintenance of the building or units, you can make application for a rent decrease to the Rent Board."

Original Victorians definitely fall in the pre June 1979 category.

Most of the victorians have been chopped up into 3 - 4 apartments though where rent control does apply.

I don’t have a stat to back this up, but many Victorian houses in SF (especially the areas that a tourist would visit) have been split into multiple units and are not single family homes.

Most victorians/Edwardians in SF are not single family homes. They just look like it from a distance...

I'd say 95% of them are actually 2-4 separate apartments.
