Providing a clean, odorless community free of debris and insects is an absolute must for facilities to provide to residents. Never should there be a reason why you cannot keep your community looking clean- even if your physical plant is older and in need of a remodel. There is nothing worse for prospective residents and their families than visiting a community and seeing a dirty living environment. You can bet your last dollar that Maine DLRS surveyors would feel the same.
Check out the following guideline for sanitation and other physical plant guidelines in your facility:
