Do You Really Need a Permit? The Truth About New NH Excavation Regulations

You have a big idea for your property. Maybe it’s a new gravel driveway, a perfectly leveled backyard for a summer patio, or clearing a spot for a new shed. You’ve got the vision, you’ve got the excitement, and you’re ready to see the dirt move.
But then that nagging question hits: Do I need a permit for this?
In New Hampshire and Massachusetts, the answer isn’t always a simple "yes" or "no." It depends on where you live, what you’re digging, and how much dirt you’re moving. Regulations change, town ordinances vary, and missing a step can lead to heavy fines or having to undo all that hard work.
At NH Excavation LLC, we believe in doing things right the first time. We handle everything from site work and grading to driveway installs, and that includes helping you navigate the red tape.
Here is the truth about excavation regulations in NH and MA as we head into 2026.
The Big Rule: NH RSA 155-E
In New Hampshire, the "big boss" of excavation law is RSA 155-E. This state law governs the excavation of "earth": which includes sand, gravel, rock, and soil.
Generally, if you are moving earth for a commercial purpose or on a large scale, you need an excavation permit from your local Planning Board. But for most homeowners, the rules fall into a few specific buckets:
1. Small Residential Projects
If you are just grading your lawn or putting in a small garden bed, you typically won't need a state-level excavation permit. However, your town might have its own rules. If you’re moving more than a certain amount of cubic yards of material, some towns require a "Fill and Grade" permit to ensure you aren't messing up local drainage or encroaching on wetlands.
2. Setbacks and Slopes
Even if you don't need a formal permit, you have to follow the rules of the road. In NH, you generally cannot excavate within:
50 feet of a property line (unless your neighbor gives written permission).
150 feet of an existing dwelling.
75 feet of any pond, stream, or river.
Getting these measurements wrong is a common mistake. That’s why we always recommend a professional site assessment before the first bucket hits the ground. Let’s Chat! We can look at your property and tell you exactly what’s required.
Massachusetts: Town by Town, Step by Step
If you’re across the border in Massachusetts, the regulatory landscape is a bit more focused on the local Department of Public Works (DPW).
Driveway and Curb Cut Permits
Planning a new driveway in MA? Most towns, like Lowell or Framingham, require a Public Way Access Permit. This is especially true if you are modifying a "curb cut": the part where your driveway meets the town road.
The Seasonal Catch: In many MA towns, you can only perform this work between April 1 and November 15. If you miss that window, you’re stuck until spring.
The Standard: Towns usually dictate how wide your driveway can be (often 12–24 feet) and what materials you must use for the apron.
Trench Safety Permits
Massachusetts is very strict about trench safety (Jackie’s Law). If you’re digging a trench deeper than three feet for utilities or drainage, you MUST have a trench permit. This is about safety, plain and simple. At NH Excavation LLC, we are fully versed in these safety standards to keep your project compliant and your property safe.
The "Dig Safe" Law: No Excuses
Whether you are in Manchester, NH, or Worcester, MA, there is one rule that applies to everyone: Call 811 before you dig.
It is the law. You must notify Dig Safe at least 72 hours (excluding weekends and holidays) before any excavation begins. This allows utility companies to come out and mark underground lines for water, gas, electricity, and fiber optics.
Hitting a gas line isn’t just expensive: it’s dangerous. When you hire a professional team like ours, we handle the Dig Safe call for you. We make sure every utility is marked and accounted for before we start the machines.
When a Project Becomes "Site Work"
There’s a difference between "digging a hole" and "site work." Site work is the preparation of a piece of land for construction. This might include:
Clearing trees and stumps.
Leveling the ground for a foundation.
Installing drainage systems.
Creating a proper base for a driveway.
Because site work changes the way water flows on your property, it almost always requires a permit. Town inspectors want to make sure you aren’t accidentally flooding your neighbor’s basement or sending sediment into a nearby stream.
As a leading excavation contractor in the region, we specialize in high-quality site work and grading. We don't just move dirt; we engineer your land so it stays stable and dry for years to come.
