Upper Darby Township requires plumbing permits to ensure that all plumbing systems and fixtures are installed and maintained in accordance with the Pennsylvania Uniform Construction Code (UCC), as adopted under Act 45, and applicable Township ordinances.

It is unlawful to perform regulated plumbing work without first obtaining all required permits and approvals.

Plumbing permits help protect public health, sanitation, and safety by ensuring that water supply, drainage, and related systems are properly installed and compliant with applicable codes.

Permit Requirements (Per State Law, Pennsylvania Uniform Construction Code)

In accordance with the Pennsylvania Uniform Construction Code (UCC), as adopted under Act 45 and enforced by Upper Darby Township, permits are required prior to the commencement of regulated plumbing work.

Commercial Buildings (All buildings other than single-family and two-family dwellings):
Pursuant to 34 Pa. Code § 403.42(a), an owner or authorized agent who intends to erect, install, enlarge, alter, repair, remove, convert, or replace any plumbing system regulated by the Uniform Construction Code—shall first apply to the Building Code Official and obtain the required permit.

Residential Buildings (Single-Family Dwellings and Two-Family Dwellings):
Pursuant to 34 Pa. Code § 403.62(a), an owner or authorized agent who intends to erect, install, enlarge, alter, repair, remove, convert, or replace any plumbing system regulated by the Uniform Construction Code—shall first apply to the Building Code Official and obtain the required permit.

Local Amendments and Pennsylvania Department of Labor & Industry Approvals (2005)

As part of the Pennsylvania Uniform Construction Code adoption process, Upper Darby Township completed the required municipal election and approval process with the Pennsylvania Department of Labor & Industry in 2005.

As a result of that process, the Township has adopted the following requirements:

Residential Accessory Structures (120 sq. ft. or more):
A UCC permit is required for all residential utility and miscellaneous use structures with a building area of 120 square feet or greater.

Residential Accessory Structures (Less than 120 sq. ft.):
A building permit is required for residential utility and miscellaneous use structures less than 120 square feet when such structures contain utilities, including plumbing systems.

Residential Alterations and Repairs:
A UCC permit is required for all residential alterations and repairs, including plumbing system work, except for those specifically excluded under Chapter 1 of the International Residential Code (IRC), as adopted by the Commonwealth of Pennsylvania.

These requirements are enforced in addition to all applicable provisions of the Pennsylvania Uniform Construction Code and Township ordinances.

Who May Apply for and Perform Work Under a Plumbing Permit

Plumbing permits may only be applied for and work may only be performed by individuals or entities who are properly authorized and licensed in accordance with State law and Township regulations.

  • Properly registered with the Pennsylvania Office of Attorney General (Home Improvement Contractor Registration), and verified with Upper Darby Township, including possession of a valid Township Business Privilege License
• Plumbing Contractors who are properly licensed and meet all Township and State requirements
• Property owners (limited circumstances only), as outlined below

Property Owners Performing Plumbing Work

A property owner may apply for a plumbing permit only for their primary residence and only if they are personally performing the work.

Property owners acting as their own contractor must comply with all applicable State and Township requirements, including:

• Compliance with the Pennsylvania Uniform Construction Code
• Compliance with all Township ordinances and permitting requirements
• Completion of all required inspections
• Submission of any required affidavits or documentation

Property owners may not perform work under a homeowner permit for rental properties, investment properties, or any property that is not owner-occupied. If a property owner is acting as a contractor, they must obtain all required State and Township licenses.

Licensing Requirements (State and Township Law)

In accordance with State law and Township regulations:

Any individual or entity performing plumbing work as a contractor must obtain and maintain all required licenses, registrations, and approvals from both the Commonwealth of Pennsylvania and Upper Darby Township.
