2021 PA Uniform Construction Code (UCC) Update: Date of Implementation on January 1, 2026

Date: 9/16/2025

The Department of Labor and Industry has submitted the regulatory package to adopt the 2021 changes into the PA UCC. The package is scheduled for consideration on October 16, 2025, with a date of implementation or “effective date of regulations” of January 1, 2026.

What this means: 

• Builders wishing to use the current 2018 PA UCC must have a design or construction contract signed before January 1, 2026, and apply for the building permit by June 30, 2026 (within six months).
• Any design or construction contracts signed on or after January 1, 2026, or permit applications submitted on or after July 1, 2026, must comply with the 2021 PA UCC.

Statutory Reference:

Act 45 of 1999 – PA Uniform Construction Code

Section 304. Revised or successor codes

Subsection (c)(4) - Where a design or construction contract was signed before the effective date of regulations for a subsequent Uniform Construction Code or International Fuel Gas Code issued under this act, the permit may be issued under the Uniform Construction Code or International Fuel Gas Code in effect at the time the design or construction contract was signed if the permit is applied for within six months of the effective date of the regulation or the period specified by a municipal ordinance, whichever is less.
