Land Clearing Permits in Duncan & Stephens County, OK

Clearing land around Duncan usually does not start with a clearing permit, but three things can still stop or delay the job: a floodplain lot inside the city, an acre or more of disturbance under state stormwater rules, and a burn ban if you plan to burn. The City of Duncan’s published permit forms include no clearing or grading permit, and no Stephens County clearing permit turned up in our research. Neither of those is the same as “no permit needed”, so this guide sets out what was found, who decides, and what to ask.

Requirements vary by parcel, scope and jurisdiction. Cut Brush can flag what commonly applies and help you find the right office. The governing authority makes the determination.

Inside Duncan City Limits

The City of Duncan handles building and land use permits through its offices at 1600 Highway 81, phone 580-252-0250. Its land use and permit applications page lists the forms it publishes, as read in October 2026: certificate of occupancy, commercial permit, demolition, new home or duplex, residential remodel and addition, pool or spa, sign, moving a building, mobile home, and generator and solar permits, plus zoning and platting applications such as lot splits, rezoning and plats. The city has adopted the 2018 International Building Codes.

None of those is a clearing, grading or land disturbance permit. That suggests clearing on its own is not a separately permitted activity in the city, but the list is a list of forms, not a ruling. If your work sits inside city limits, call the city and describe it before you schedule anything, especially if it is part of a larger project.

Two situations make that call more important.

Building after clearing. If the clearing is the first step toward a house, shop or commercial building, the building permit is what the city will want, and the clearing becomes part of that project.

Ground in the floodplain. The city’s floodplain FAQ says: “The City of Duncan requires a Floodplain Development Permit along with a building permit for remodeling, improving, expanding, or rebuilding your home, buildings, parking areas, etc. within the floodplain.” Duncan takes part in the National Flood Insurance Program, which is why those rules exist. If a creek runs through or near your lot, ask whether any part of it is mapped floodplain before the work is planned, because that can change where a house pad or drive goes.

Stephens County and the Rural Towns

Outside Duncan, most land in Stephens County is unincorporated farm and ranch ground. We did not find a county clearing permit for that land. That is unconfirmed, so ask the county commissioners’ office about your road.

The other towns in this service area, including Marlow, Comanche, Velma, Walters, Temple, Waurika and Ringling, are their own jurisdictions. Their rules were not researched for this guide. If your land is inside one of them, call that town hall the same way you would call Duncan.

State Stormwater: The One-Acre Line

The rule that most often applies is statewide. The Oklahoma Department of Environmental Quality’s 2022 OKR10 general permit for construction stormwater covers construction activity disturbing one acre or more, or less than an acre when it is part of a larger common plan of development or sale over an acre.

Three details matter for a clearing job:

• Timing. DEQ says a permit is required before construction activity can start at a site, so coverage comes before the machine, not after.
• What counts. Clearing that is the first stage of a house, a commercial pad or a subdivision is part of that project’s disturbance. Whether a pasture or timber job on its own counts is DEQ’s call, so ask before assuming either way.
• Cost. As read in October 2026, DEQ lists a $100 application fee plus an annual fee of $347.71 for new construction sites. Agency fees are the owner’s.

Coverage means a notice of intent and a stormwater pollution prevention plan for the site.

Burning and Burn Bans

If the plan is to push brush into piles and burn them, Oklahoma’s burn ban system is the constraint. The Oklahoma Department of Agriculture, Food and Forestry explains that there are county-issued burn bans and Governor-proclaimed burn bans. Violating a county ban carries a fine of not more than $500, imprisonment for up to a year, or both; violating a Governor’s ban raises the fine to not more than $1,000.

Bans come and go with the weather, and Oklahoma Forestry Services posts the current ones. We do not list Stephens County’s status here because it can change from one week to the next. Check it on the day, not the week before.

Mulching avoids the question entirely. The cedar and brush are ground where they stand, so there is no pile to burn and no ban to wait out.

A Simple Order of Steps

1. Find out whether the land is inside Duncan or another town, or in the unincorporated county.
2. If it is in a town, call that town and describe the work. In Duncan, ask about the floodplain.
3. Measure how much ground will be disturbed. At an acre or more, ask DEQ about OKR10 coverage before work starts.
4. Decide what happens to the brush. If burning is the plan, check the burn ban on the day.
5. Then book the work.

Frequently Asked Questions

Do I need a permit to clear my own land near Duncan?

Often not for the clearing itself, but check. Duncan’s published forms include no clearing permit, and no Stephens County clearing permit was found. A floodplain lot in the city, a building project or an acre or more of disturbance can each bring a permit into it.

What does a Duncan floodplain permit cover?

The city requires a Floodplain Development Permit along with a building permit for remodeling, improving, expanding or rebuilding homes, buildings, parking areas and similar work within the floodplain. Ask the city whether your lot is mapped floodplain.

Can I burn brush piles during a burn ban?

No. A burn ban is a ban on burning, enforced by state law, with fines and possible jail time for violations. Grinding the brush in place avoids the issue.
