Permit likely required

Most likely yes. Accessory dwelling unit (adu) usually requires a permit in Oklahoma. Confirm the specifics with Unincorporated Pontotoc County.

Oklahoma law requires a permit from the city, town, or county before construction of buildings covered by the OUBCC codes; the only statewide exception is that no State Fire Marshal permit is needed for a single-family home or duplex in an unincorporated area (74 O.S. 324.11). The IRC appendix on accessory dwelling units (Appendix BC) is not part of Oklahoma's statewide code unless a local jurisdiction adopts it, so ADU-specific size and design rules depend on local adoption and zoning (OAC 748:20-6-3(a)). Oklahoma's IRC amendment on storm shelters says that where shelters are provided on a lot with more than one dwelling, one is needed for each dwelling unit, not counting ADUs (R307.3.4.1 as amended). New residential construction that requires a building permit must include smoke detectors or the wiring for them (74 O.S. 324.11a(D)).
