Greer County Oklahoma Landlord-Tenant Law: Guide for Mangum, Granite & Southwestern Oklahoma Rental Property Owners
Greer County carries one of the most unusual territorial histories of any county in the United States. From 1860 until 1896, the state of Texas actively administered this territory as “Greer County, Texas” — collecting taxes, operating courts, and recording land transactions — based on its interpretation of the 1819 Adams-Onís Treaty boundary. The dispute was resolved by a U.S. Supreme Court ruling in 1896 that awarded the territory to the United States and ultimately to Oklahoma Territory, ending Texas’s claim. Mangum, which had been designated the county seat by Texas in 1886, continued in that role under Oklahoma jurisdiction — making it one of the few American county seats that served under two different jurisdictions.
Today Greer County is a quiet, declining agricultural county in Oklahoma’s far southwest, where the Gypsum Hills’ cream and red formations rise above the Red Fork tributaries and Quartz Mountain’s dramatic quartzite outcroppings overlook Lake Altus-Lugert at Quartz Mountain State Park. With approximately 5,491 residents in 2020, the county is one of Oklahoma’s smaller counties, and its population has declined steadily since its 1930 peak as agricultural mechanization and urban migration reduced the need for farm labor. The Oklahoma State Reformatory in Granite is a significant institutional employer, providing corrections employment that anchors part of the county’s economic base and significantly skews the county’s demographic statistics — including a male-to-female ratio of approximately 125:100 that reflects the incarcerated population.
The ORLTA in Greer County
All residential rental relationships in Greer County are governed by the Oklahoma Residential Landlord and Tenant Act (ORLTA), codified at Oklahoma Statutes Title 41. No local ordinances modify the ORLTA in Greer County. There is no rental licensing requirement and no rent control — Oklahoma has no statewide rent control statute. For nonpayment of rent, a five-day pay-or-quit notice (rent only — no late fees) is required before filing a Forcible Entry and Detainer (FED) action. For other lease violations, a fifteen-day notice to cure or quit is required. Month-to-month tenancies require thirty days’ written notice to terminate. Non-emergency entry requires twenty-four hours’ advance notice. Security deposits have no statutory cap but must be held in an FDIC-insured Oklahoma institution, with the 45-day return clock beginning only after termination, possession delivery, and a written tenant demand. Self-help eviction is prohibited statewide.
Eviction Procedure at the 3rd Judicial District Court
FED actions in Greer County are filed at the Greer County Courthouse, 201 W. Lincoln, Mangum, OK 73554, phone (580) 782-3664, open Monday through Friday from 8:00 AM to 4:00 PM. Greer County is part of Oklahoma’s 3rd Judicial District. After the applicable notice period expires, the landlord files the FED petition, pays the filing fee, and is assigned a hearing date. Oklahoma’s prevailing party attorney fee provision means both parties may seek attorney fees — procedural accuracy from notice through judgment matters even in the smallest markets.
The Corrections Economy in Granite
The Oklahoma State Reformatory in Granite is one of the county’s two or three largest employers and creates a distinctly institutional character for that community. Corrections officers, administrative staff, and support workers employed at the Reformatory represent the most stable and documentable portion of Greer County’s private employment base — year-round government positions with regular pay cycles and predictable income. For landlords in Granite in particular, corrections employment is a strong tenant income source. Landlords should note that the Reformatory’s incarcerated population counts in the county’s census figures but is not the relevant tenant pool — Fair Housing-compliant screening criteria applied consistently to civilian applicants is the appropriate approach, regardless of the demographic context surrounding the facility.
