The problem with 13D. One & two family is not a criterion. There needs to be a square footage limit overall and some sort of flag for the uninitiated (that would be everyone but us) that 13D & 13R are not designed to protect your property. The damned architect lets the owner choose his amenities, he should be able to know and describe to that owner his options in fire protection. And we, being the initiated, are to blame for his ignorance.
