Converting a basement into an apartment or ADU in San Francisco

The basement, which was entirely for storage, makes the perfect place to add an accessory dwelling unit. With a living/dining area, kitchen, bathroom, and patio, this will be a great home for a single person, a couple, or a pair of roommates. Plus, the homeowners don’t have to give up all of their storage. A storage room accessible from the main home is included in the plan.

If they move their grandparents into the unit, they’ll save at least $24,000 per year on housing. If they use the space for the immediate household, they’ll save by not moving to a larger, more expensive home (and they’ll get to stay in the neighborhood they love).
