Summary
A spa or hot tub is defined by Chester County as a structure up to 48 inches deep with recirculation or air injection that is not emptied after each use. Backyard spas normally need only a municipal permit; a spa with a lockable safety cover meeting ASTM F1346 is exempt
"Hot Tub or Spa": A structure, designed to contain water, having a maximum depth of 48 inches used in conjunction with water recirculation systems or air injection, and utilizing hot, cold, or ambient temperature water which is not emptied after each individual use.
Full Breakdown
Chester County Health Department Rules §602.1.2.11 define a hot tub or spa as a structure up to 48 inches deep using recirculation or air injection and not emptied after each individual use. Public/commercial spas fall under the county's Public Bathing Place registration (§602), and their turnover period must be 30 minutes or less (§602.4.4.3). For a residential spa, the PA ISPSC 2018 provides that a spa or hot tub with a lockable safety cover complying with ASTM F1346 does not require the perimeter pool barrier. Check your municipality for the permit.
Violations & Fines
A public spa operating without registration, or with an inadequate turnover rate, may have its Certificate of Registration suspended or revoked by the Health Department.
