Permits and Approvals for Underground Utility Work

A general guide to which permits, utility approvals and inspections usually apply to underground work, and who to ask.

Rules differ by place

Cities, counties and utility districts set their own permit rules. Nothing here replaces checking with the local permit office and the utility, which are the final word on your project.

Building and plumbing permits

New water and sewer lines on private property often need plumbing or utility permits, and an inspection of the open trench. Repairs are sometimes handled differently from new work, so ask.

Right of way and road permits

Digging in a public street, a sidewalk or a road edge usually requires a right-of-way permit, traffic control and sometimes a bond or deposit. Boring under a road has its own rules.

Utility tap and connection approvals

Tapping a water or sewer main requires the utility approval and fees. Electric and gas connections are scheduled with the provider. Ask early because some approvals take weeks.

Septic, wells and environmental

Septic systems are permitted by the health authority and need a soil evaluation. Work near streams and wetlands may need environmental approvals. Stormwater rules apply to larger sites.

How we help

We tell you which approvals commonly apply, prepare plans and information for the permit office and coordinate inspections. The owner or the contractor pulls the permit depending on the arrangement, and we agree on that at the start.

Our advice in one sentence

Ask the permit office and the utility early, and agree who pulls each permit before work starts.

Questions

Quick answers.

Do I need a permit for a repair?

Often a repair needs less than new work, but rules vary. Ask your local office.

Who pulls the permit?

It depends on the agreement. Settle it before the work begins so nothing is missed.

Do HOA rules matter?

Yes. Some associations have rules about digging and restoration. Check before you start.
