Summary
Pittsburgh's Building Code requires public and commercial hot tubs and spas to meet the ANSI/NSPI-2 1999 national spa standard, but expressly exempts hot tubs and spas accessory to a one- or two-family home from that standard.
3109.1.2 A hot tub or spa that is not accessory to a one- or two-family dwelling shall comply with this chapter and the "American National Standard for Public Spas" issued by ANSI and NSPI (ANSI/NSPI-2 1999).
Full Breakdown
Section 3109.1.2 of the city's Uniform Construction Code amendments (Title 10, Building) states that a hot tub or spa not accessory to a one- or two-family dwelling must comply with the ANSI/NSPI-2 1999 public spa standard. Pittsburgh applies the commercial-facility standard to hotels, gyms, and similar public installations, not to backyard tubs. Pittsburgh also adopts Appendix G of the International Residential Code (Pittsburgh Code § 1002.01(14)) as part of its building code, which governs residential swimming pools, spas and hot tubs. The Bureau of Building Inspection administers permits under Title 10; prefabricated pools under 24 inches deep are permit-exempt under § R105.2, but the code lists no matching depth exemption naming hot tubs specifically.
Violations & Fines
Title 10 violations are punishable under § 1001.10 by a fine of up to $1,000 plus costs per offense, with imprisonment up to 90 days in default of payment; each day a violation continues counts as a separate offense.
