Granny Flats can be detached or attached to the main house, and are typically found in the front of properties, but can also be located in the backyard. ADUs / Granny Flats are often referred to as mother-in-law-quarters, guest houses, or granny flats and can be a great way to make your home available to multiple generations.
While you’ll likely find casitas in higher value homes (a quick Zillow search reveals that homes with advertised casitas average well over 2 million dollars), anyone with space and budget should consider adding one. This is especially true in areas and price ranges where a guest house is expected. Areas like Rancho Santa Fe, Del Mar, Carmel Valley, Del Sur, Poway, Fairbanks Ranch, Carmel Canyon, and La Jolla Farms all feature real estate that is in high demand.
