Compare the property’s permit history and official city records against the actual layout. Kitchens, bathrooms, or entire units that don’t appear in permitted documents are unwarranted. Architectural inconsistencies and odd room configurations can also signal past work. Illegal units are very common in San Francisco, and some offer real value while others present risk. I help buyers understand the legal implications, insurability, and whether legalization is feasible before they make any commitments.
