Guide to UR and UC Permits – Lateral Repairs and Connections to Public Sewers

Information
When you repair a sewer lateral or need a new connection to the public sewer system either in the right-of-way or in a public easement, a permit is needed. This guide provides sewer contractors and property owners information about Environmental Services' UR and UC Permits.
On this page

A sewer lateral connects a property to the public sewer main, which is most often located in the street. The property owner is responsible for maintenance of part of the pipe, and the City is responsible for the other part. The City's part is often called the "branch."

Diagram of a Typical Sewer Lateral and Its Maintenance Responsibilities

Diagram shows a street and house with a pipe, labeled, sewer lateral connecting the house to the public sewer main in the street. Diagram shows city maintains the part of the pipe from the main to the curb. The remainder is labeled as property owner maintains.

See Portland City Code 17.32 and Administrative Rule ENB-4.17 for more information on City and property owner maintenance responsibilities of the lateral in a right-of-way or public sewer easement.

When repairing a sewer lateral or installing a new connection, you will need separate permits for the work on private property and for work in the right-of-way. The Bureau of Development Services permits sewer lateral work on private property through plumbing permits (PT Permit). The Bureau of Environmental Services maintains the public sewer system and issues UR and UC permits for work in the right-of-way or in a public easement. 

About UR Permits (lateral repair permit)

A UR Permit is required when you need to repair a sewer lateral. For the portion of the repair work in the the public right-of-way or sewer easement, a UR Permit is required. For the portion of the work on private property, a plumbing permit (PT Permit) is required.

Lateral Repairs Require a UR Permit for the Work in the Right-of-Way

Diagram shows house with sewer lateral connecting it to the public sewer main. Part of the pipe, from the house to the curb, is labeled lateral repair work. That work is divided into two sections. The part from the curb to the property line requires a UR permit; a sewer contractor must perform the work; and PBOT right-of-way inspects the work. The other portion requires a PT Permit; a contractor, plumber, or property owner performs the work; and Development Services inspects the work.

Other less common situations in which a UR Permit is needed:

  • Repairing a sewer lateral that is connected to a public sewer on private property (usually in a public sewer easement).
  • A lateral repair connecting to a City branch in a public alley.
  • Repairing a private sewer line in the right-of-way.

About UC Permits (new lateral connections)

A UC Permit is required when your property needs a new connection to the public sewer system. This occurs either when the new sewer lateral connects to an existing public connection – a City branch – or when the new sewer lateral needs to extend from the building all the way to the public sewer main. 

A New Lateral Connection to an Existing Branch Requires a UC Permit

Many sewer mains have existing public laterals or branches. Typically, these extend from the sewer main to the curb. If they are in good condition, then a new development can connect directly to the existing branch if you can install the new lateral without an angle in the right-of-way. A UC Permit is required for the work in the right-of-way. A plumbing permit is required for the work on private property.

Diagram shows a new lateral being installed from building to curb. The part of the new lateral from the curb to the property line requires a UC Permit; a sewer contractor must perform the work; and a right-of-inspector must inspect the work. For the work on private property, a PT Permit is required; a contractor, plumber or the property owner performs the work; and Development Services inspects the work.

City staff may be able to help review City records to provide an approximate location of an existing sewer branch, but the information is not guaranteed. Some of Portland’s sewers are more than 100 years old, and many factors can make it difficult to provide exact locations. 

A New Lateral Connection to the Public Sewer Main Requires a UC Permit

In situations where no existing public connections exists, new development will require a lateral installed from the building all the way to the public sewer main.

Diagram shows a new lateral being installed from building to the sewer main. The part of the new lateral from the main to the property line requires a UC Permit; a sewer contractor must perform the work; and a PBOT right-of-way inspector inspects the work. For the work on private property, a PT Permit is required; a contractor, plumber or the property owner performs the work; and Development Services inspects the work.

This UC Permit type requires greater application review by City staff and greater construction coordination by the sewer contractor. Excavation in the street increases the need for traffic control and site safety measures. Other important utilities are buried in the street, such as water, gas, and telecommunication service lines and mains. These utilities may need to be relocated or protected during construction.

Depending upon the sewer main’s age, material, size and/or location, UC Permit review staff may need to consult with other City staff to determine if specific permit conditions are required. This could include a pre-construction meeting with inspection staff or having the City maintenance crews install the connection at the main. Additionally, special connection requests require approval from Environmental Services engineering staff. Examples of special connections are a deep connection riser or inside drop in a maintenance hole. Refer to the City Standard Drawings & Details Details P-250 to P-299.

Some rare connections are so risky or complicated that they cannot be permitted under a UC Permit. Connections crossing light rail or streetcar tracks are examples. Contact UR and UC Permitting staff for guidance. A Public Works Permit will likely be needed.

Applying for UR and UC Permits

Sewer contractors typically submit applications for UR and UC permits. The contractor doing the work is required to sign the permit application even if they are not submitting it. Sewer contractors must have an active license from the Oregon Construction Contractors Board and active PBOT Street Use Insurance and Bond to work in the right-of-way.

Applications for UR Permits for lateral repairs can usually be reviewed in 1-2 business days. Following payment, Environmental Services staff will email your permit to you.

Applications for UC Permits requesting connections to existing branches can typically be reviewed in 1-2 business days. Environmental Services staff will email your permit to you.

Applications for UC Permits requesting connections to a sewer main may take more than 1-2 business days to review. If you are requesting to connect to larger, older, or clay sewer mains or if the connection requires an inside drop or deep connection riser, application review will take longer. Your permit may require special conditions such as a preconstruction meeting, right-of-way inspection staff being present during the tap or tee install, or the conditions may require that City crews install the connection at the main.

No work may start until Environmental Services has issued the UR or UC Permit.

Frequently Asked Questions About the UR and UC Permitting Process

How do I pay for and get an issued UR or UC Permit by email­­?

Permitting staff will email you payment information so you can pay at DevHub. After payment, you reply using the email thread that you’ve paid, and staff will email to you the issued permit.

How do I call for an inspection once I have my issued permit?

PBOT right-of-way inspectors will inspect the lateral work and surface restoration. When you are ready for inspection, call the inspection phone number on your issued permit and leave a voicemail with your:

  • UR or UC Permit Number
  • Property address
  • Requested time of inspection
  • Phone number for the onsite contact

What if there’s an error on my issued permit?

Contact the UR and UC Permitting Team to request corrections and get an updated permit.

Will my permit expire and can I get a refund if the work is cancelled?

UR and UC permits expire 180 days after they are issued. Extensions of up to an additional 180 days can be requested prior to the permit’s expiration date.

For refunds, applicants can get an 80 percent refund of Environmental Services' fees (per City Administrative Rule ENB-4.29). Refund requests must include a copy of the signed contract with the property owner that pre-dates the permit application.
