Zoning, building permits and septic rules in the Town of Kellyville, Oklahoma

The Town of Kellyville, Oklahoma, in Creek County, requires a building permit from the Town Clerk-Treasurer for any building built, enlarged, altered or moved, with alterations triggering a permit once they cost more than $1,0001. Kellyville also zones its own land into Residential, Commercial, Industrial and Agricultural districts2. Septic permits come from Oklahoma DEQ, which runs the program statewide3.

Do you need a building permit in Kellyville, Oklahoma?

Yes. Kellyville's town code says no building or other structure may be built, enlarged, altered or moved without a building permit issued by the Town Clerk-Treasurer1. For alterations, a permit is required when the outside appearance changes or the work will cost more than $1,000, and a permit is also required to move a building into or within town1. The permit covers the initial plumbing and electrical installations connected with the building1.

This is a town rule. Unincorporated Creek County works differently: the county says it is not issuing building permits or doing inspections outside incorporated places9. Land inside Kellyville does not get that break.

Who issues building permits in Kellyville, and how do you apply?

The Town Clerk-Treasurer issues building permits in Kellyville, and an applicant submits an application plus the reasonable information the Clerk-Treasurer requests10. The fee is paid once the application complies with the code and state and local laws10. The Town Board of Trustees may set the fee, and a current fee schedule is kept in the Clerk-Treasurer's office11. Call Town Hall at 918-247-6160 or write clerk@kellyvilleok.gov to get the current fee12.

The town has adopted the latest edition of the International Building Code, with local changes in Chapter 150 of its code13. We could not confirm how building inspections or certificates of occupancy work inside town limits, so ask the Clerk-Treasurer before you pour a foundation.

Does Kellyville have zoning, and what does it mean for homes, lot size and setbacks?

Kellyville has its own zoning. The town code divides land into Residential (R), Commercial (C), Industrial (I) and Agricultural (A) districts2.

In the Residential district, a home needs at least 1,000 square feet of living space, the code lists a minimum lot size of 3,750 feet, and buildings are limited to 26 feet in height41415. Residential setbacks are 25 feet front, 15 feet rear and 10 feet side5.

In the Agricultural district, the minimum lot size is 2 acres and the height limit is 35 feet1617. Agricultural setbacks are the same 25 front, 15 rear and 10 side6.

Proposed subdivisions inside town are reviewed for drainage, utilities and flood damage18.

How do septic permits work in Kellyville, Oklahoma?

Oklahoma DEQ, not the town, runs the on-site sewage program that issues septic permits3. Before a new system is installed or an existing one is modified, an Authorization to Construct must be purchased and issued by DEQ7. Reach DEQ's Environmental Complaints & Local Services division at 405-702-010019.

We could not confirm whether the town sets extra septic rules or requires sewer hookup for lots inside its limits. Ask Town Hall whether town sewer reaches your lot before you plan a septic system.

Creek County's soils matter too: only 5.3% of the county's soils are rated not limited for a conventional drain field, so expect a soil evaluation and possibly an engineered system20.

Can you live in an RV or tiny home in Kellyville?

We could not confirm a Kellyville rule on living in an RV, camping on private land, or placing a tiny home inside town limits. Do not assume the county's tiny-home rules apply: those cover unincorporated Creek County, not land inside the town. Ask the Clerk-Treasurer at Town Hall, 918-247-6160, which district your parcel is in and whether an RV, tiny home or manufactured home is allowed there12.

If you plan a manufactured home, Oklahoma requires that an occupied one be treated as a permanent installation21.

Building a home in Kellyville: the steps, in order

  1. Call Town Hall at 918-247-6160 and confirm your parcel's zoning district (R, C, I or A)212.
  2. Check the district's minimum home size, lot size, height and setbacks45.
  3. Ask whether town sewer serves the lot; if not, apply to Oklahoma DEQ for an Authorization to Construct for septic7.
  4. Submit a building permit application to the Town Clerk-Treasurer and pay the fee10.
  5. If the site has a flood hazard, the permit issues only after the Building Official finds it reasonably safe from flooding22.
  6. Ask about inspections before work begins; we could not confirm the town's inspection rules.

What stays with Creek County, and what to check before you buy in Kellyville

Land outside Kellyville's limits follows Creek County's rules, not the town's; see the Creek County page for unincorporated land. Confirm the parcel is inside town limits before you rely on anything above.

A private well for household use, livestock or irrigation of under 3 acres needs no state water permit8; we could not confirm any town rule on wells. Creek County's effective property tax rate is 0.7%23.

Watch-outs

  • We could not confirm building inspection, certificate of occupancy, RV, tiny-home or owner-builder rules inside Kellyville; ask the Clerk-Treasurer at Town Hall12.
  • Oklahoma DEQ requires an Authorization to Construct before a septic system is installed or modified, and individuals not certified through DEQ may install only one system per calendar year7.
  • The Residential district's minimum lot size is written as 3,750 feet in the town code, so confirm the unit with the Clerk-Treasurer14.
