Add a Second Bathroom
SECOND BATHROOM PROTOCOL

The second bathroom protocol does not apply to multi-family sites with four or more dwelling units. The Second Bathroom Protocol cannot be used to add a bathroom to create an Auxiliary Dwelling Unit (ADU) or a JADU, it must be within the existing dwelling unit, and it cannot be designated as the Master Bathroom (Rule 24-A-4). The second bathroom is for convenience only.
Can the Second Bathroom Protocol be Used to Add a Bathroom if a One-bath Dwelling Unit is Demolished and Rebuilt with Two Baths?
Yes. A documented Water Use Credit from MPWMD for the permanent abandonment (demolition) of a one-bathroom dwelling unit constructed prior to May 16, 2001 is regarded as an “existing” dwelling unit for 120 months (ten years) following demolition.
