Well Drilling Permits: What Homeowners Need To Know Before Digging A Water Well

If you’re thinking about digging a water well on your property, don’t start with the drilling process. Start with the rules. Before you move forward, you need to know whether your property can support a well, what permits apply, and what the project may cost.

Well drilling permits are local or state approvals that allow you to drill a private water well on your property. In most cases, the permit process helps the relevant agency review where the well will go, how it will be built, and whether it meets local health, safety, and land-use requirements.

Your county, city, or state may require a water well permit. Some jurisdictions issue a general well permit, while others may require separate approvals for drilling, installation, or water use.

These permits often focus on things like:

• The proposed well location

• Distance from septic systems and other contamination risks

• Setbacks from structures and property lines

• Construction standards for the well

• Whether inspections or water testing will be required after installation

Wondering, “Do I need a permit to drill a well?” The answer is usually yes, but you’ll need to check with one or more local or state agencies before work begins.

Depending on where you live, requirements may come from your building department, planning office, county health department, or state water agency. Some areas also charge permit fees that you’ll need to account for. 

Skipping a permit for water well work can lead to fines, delays, or a requirement to stop and redo the project. 

Whether it’s legal to drill your own well depends on your location.

Some states or local jurisdictions let homeowners install certain types of wells on their own. Others require a licensed contractor for all drilling work, or for deeper wells. Even if local rules allow owner-installed wells, restrictions may still apply based on depth, water use, or the type of system you’re installing.

Before you plan a DIY approach, confirm whether your area allows owner-installed wells, whether licensing rules apply, and whether you’ll still need inspections or reporting after installation.

Digging a water well on your property isn’t a case of just picking a spot and starting to drill.

The best location depends on your property’s geology, groundwater conditions, contamination risks, and local setback requirements. 

In many areas, wells must sit a minimum distance from septic tanks, drain fields, buildings, and property lines. You also need enough access for drilling equipment and future maintenance. 

That means site conditions and local rules work together. A location that seems convenient may still fail to obtain a well drilling permit because it sits too close to a septic system or doesn’t meet local spacing rules.

A water well permit application often requires parcel details, the proposed well location, distances from structures and septic systems, and information about how you plan to use the water. Some jurisdictions also require inspections or water testing after the well is installed. You can check local regulations on water testing for your state on the EPA’s website.

This is why property documentation matters. If your permit office wants to see where the well will sit in relation to the rest of the lot, a site plan can make that much easier to show.

A site plan can show property lines, existing structures, driveways, septic systems, and the proposed well location in one clear document. That can make the application easier to review, especially when spacing and setbacks matter.

For homeowners preparing well permit or planning documents, My Site Plan can create detailed site plans using publicly available data and client-provided information, helping you submit a clearer application without having to draw the plans yourself.

The average cost of digging a water well depends on depth, drilling method, geology, equipment, and permit fees.

According to real project data from Angi, drilling a water well usually costs around $3,000 to $9,000, though deeper wells can cost much more. For example, a 50-foot well costs between $1,775 and $3,060, while a 200-foot well costs $7,100 to $12,240. 

Drilling is only part of the total cost. You may also need to pay for casing, screens, pumps, pressure tanks, electrical work, water testing, permit fees, and site restoration. That’s why the full installed cost often ends up higher than the drilling quote alone.

You can also expect to pay between $200 and $500 for your water well permit.

A permit for a water well can get delayed when the application leaves too many open questions.

Common issues include missing parcel details, a proposed well location that sits too close to a structure, not meeting setback requirements, contractor licensing issues, or a site layout that the reviewer can’t interpret clearly.

You can avoid a lot of back-and-forth by confirming local requirements early and gathering your lot information before you apply.

If your local agency requires a site plan as part of your water well permit or well drilling permit application, My Site Plan can help. We create detailed remote site plans for permits, planning, and property improvements, so you can show your proposed well location clearly and move your project forward with less hassle.

• Most homeowners need a well permit. Before drilling, check your state, county, and local requirements to see what approvals apply.

• You can’t drill a well anywhere on your property. Setbacks, septic systems, geology, and site access all affect where a well can go.

• DIY drilling isn’t legal everywhere. Some areas allow owner-installed wells, while others require a licensed contractor.

• A water well permit application may require more than a form. You may also need parcel details, a proposed well location, and spacing information.

• The total cost of a well usually goes beyond drilling alone. Pumps, electrical work, testing, permit fees, and restoration can all add to the final price.

• A site plan can make the permit process easier. It helps show property lines, existing features, and the proposed well location in one clear document.
