April 1 Code Updates

Building code updates that have been recently implemented include:

Adoption of the 2021 Building Code and the 2020 National Electrical Code, along with PG County’s Code, Subtitles 4 and 9 amendments.

PG County’s Council passed CB-047-2025 and CB-053-2025 in October and September 2025, respectively. These bills introduced code amendments to PG County’s Code, Subtitle 4 – Building Code and Subtitle 9 – Electrical Code, to align with the new editions of the International Code Council and National Fire Protection Association codes, along with their referenced standards. These are as follows:

  • 2021 International Building Code (IBC)
  •  2021 International Energy Conservation Code (IECC)
  • 2021 International Existing Building Code (IEBC)
  • 2021 International Mechanical Code (IMC)
  • 2021 International Residential Code (IRC)
  • 2021 International Swimming Pool and Spa Code (ISPSC)
  • 2021 National Fire Protection Association (NFPA) Life Safety Code NFPA 101
  • 2021 National Fire Protection Association (NFPA) Fire Code NFPA 1
  • 202 National Fire Protection Association (NFPA) National Electrical Code (NEC) NFPA 70

Any new building or trade permit applications filed on or after March 1, 2026, need to comply with the new code and the amendments mentioned above.

TPIP Updates

Prince George’s County now requires participation in the Third-Party Inspection Program (TPIP) for all sprinkler, fire alarm, electrical, and mechanical work on tenant build-outs, regardless of project value. While full, upfront TPIP enrollment isn’t required, owners must retain and pay for approved third-party inspectors for these trades, which adds costs and coordination. This procedural shift contradicts published guidance and requires immediate adjustments for project planning. For more details on compliance, visit Prince George’s County.
