Applicable Codes

The City of Philadelphia adopted the State of Pennsylvania's Act 45, the Uniform Construction Code (UCC) on July 8, 2004. The UCC includes very specific regulations regarding the administration and enforcement of construction codes.

Pursuant to the Pennsylvania Uniform Construction Code (UCC), the Commonwealth has adopted the 2015 International Code Council's (ICC) family of codes which are available for free online, and become effective October 1, 2018. Philadelphia is provided an exception in the UCC to adopt the 2018 International Codes for non-residential construction. 

The Philadelphia Building Construction and Occupancy Code contains the local modifications to the adopted ICC codes. Please be aware that for plumbing-related items, Philadelphia currently uses the Philadelphia Plumbing Code and does not use the International Plumbing Code or the plumbing provisions of the International Residential Code. 

The 2018 International Codes (ICC Codes) and the 2015 International Residential Code (IRC) become effective October 1, 2018. Pursuant to the UCC, if a design or construction contract for proposed work was signed before October 1, 2018, the permit application may comply with the 2010 Philadelphia Building Code (2009 ICC Codes), with reference to the accessibility provisions of the 2015 International Building Code. 

Applications filed on or after April 1, 2019, must comply with the 2018 Philadelphia Code, incorporating the 2018 ICC Codes (and the 2015 IRC) with local and state modifications.

In addition, the complete 2013 Philadelphia Fire Code that merges Philadelphia amendments with the 2009 International Fire Code text is available for purchase at the ICC online store

The Philadelphia Administrative Code identifies provisions for administrative, enforcement, and appeals regulations for the technical codes which regulate the site, construction, alteration, addition, repair, abatement, removal, demolition, location, occupancy, and maintenance of all buildings, structures, and building service equipment within the city of Philadelphia. This Code also incorporates the administrative provisions of the UCC for construction code enforcement. 

The Philadelphia Property Maintenance Code exists to protect public health, safety, and welfare through the regulations on the maintenance of existing structures and properties.

The Philadelphia Zoning Code exists to promote the public health, safety, and general welfare of the city of Philadelphia's citizens and visitors. It was updated in December 2011 for the first time in 50 years, and the new code became effective on August 22, 2012.
