What is the correct definition for Single Family?
Is it defined as a single "housekeeping unit"? Meaning one kitchen, one main front door entry, one residential building, all rooms connecting to a common area within the dwelling, (no separate servant, guest, student, or mother-in-law cottages?)
If the "cottage" is attached by trellis, or pergolla, or covered breezeway, is it considered attached and not a separate building?
Is a separate sleeping area over a garage with a microwave, a bar sink, and bath room considered a separate dwelling for Single Family dwelling definition purposes, if it has a outside door?
Would a "family" of 20 or more workers, relatives, or college students sharing a "single housekeeping unit" residence still be considered Single Family? When does this become an illegal boarding house, half-way house, ranch house, dorm, etc.
If people are unrelated, must it be determined to be Multi-Family? Does the city have good legal basis to require proof that occupants are in fact of a related "single family" if the question arises.
Is there a recommended model code where these types of questions have already been answered?
