Businesses with less than how many square feet of floor area need only one bathroom?

In Massachusetts plumbing code, the requirement for the number of bathrooms in a business is based on the total floor area of the establishment. Specifically, for businesses with less than 1200 square feet of floor area, only one bathroom is mandated. This regulation aims to balance the needs of smaller businesses with practical accessibility and public health considerations. The threshold of 1200 square feet is established to ensure that businesses of a smaller size are not burdened with excessive restroom requirements, which could be financially and logistically challenging to maintain. Larger businesses, on the other hand, are required to provide additional facilities to accommodate more patrons and staff, reflecting an increased demand for restroom access as the size of the business grows.
