Delaware County does not issue building permits for its unincorporated land; the state’s code commission lists it as a non-issuing jurisdiction. Grove, Jay and West Siloam Springs do their own plan review, permitting and inspections. Outside the towns, the permits that matter come from Delaware County Emergency Management as floodplain administrator (918-541-7666), the Grand River Dam Authority for docks and shoreline work on Grand Lake, DEQ for septic systems and the State Fire Marshal for commercial buildings.
Who issues permits in Delaware County?
No county office permits or inspects homes and buildings outside the towns. The county’s offices at 327 S. 5th St. in Jay, where the County Clerk answers on 918-253-4520, are listed by the Uniform Building Code Commission as issuing no permits, and Delaware County is not on the State Fire Marshal’s July 2026 list of counties with their own building programs, which leaves the State Fire Marshal as the authority for commercial construction there.
The OWRB’s floodplain administrator list names Delaware County Emergency Management, 432 S. 9th St., Jay (918-541-7666), as the county floodplain contact, and the same office is listed for Bernice and Jay.

Outside Grove and Jay there are no county electrical, plumbing or mechanical permits. Contractors in those trades hold Oklahoma Construction Industries Board licences, and the cities issue their own trade permits.
Septic: DEQ permits on-site sewage systems. Its 581 report sets what the lot can take, DEQ must issue an Authorization to Construct before installation, and the system is inspected by DEQ or self-inspected by a certified installer.
Commercial buildings: where no city or county has an agreement with the State Fire Marshal, the State Fire Marshal holds jurisdiction, and it reviews plans only through its online Accela Citizen Portal.
Delaware County permit fees
The county charges no building permit fees because it issues no building permits; ask Delaware County Emergency Management (918-541-7666) whether a floodplain fee applies. Fees come from whichever agency reviews the project: the town inside Grove, Jay or West Siloam Springs, the Grand River Dam Authority for lake permits (its lake permitting page links an online payment center), DEQ for septic authorizations and the State Fire Marshal for commercial plan review.
Grand Lake dock and shoreline permits
On Grand Lake, the Grand River Dam Authority’s lake rules apply on GRDA waters and lands. Under those rules, nobody may build, change the footprint of, install, relocate, transfer or operate a private dock, boat house or breakwater until GRDA has issued written permission on a completed application; commercial docks also need Federal Energy Regulatory Commission approval. After the work, GRDA carries out a final inspection before it issues the permit.
