Oklahoma County, OK Property Maintenance: Vacant Lot Maintenance (2026)

Oklahoma County vacant lot enforcement most active in Oklahoma City under §41-45 and §41-80. All vacant lots — whether improved (with building) or unimproved — must be maintained to prevent blight. Requirements: grass and weeds kept under 12 inches, no accumulated trash/debris/illegal dumping, no discarded appliances or furniture, structures (if any) secured against trespass with boarded or glazed openings, no vermin harborage, and reasonable perimeter maintenance. Vacant and abandoned structures must be registered annually with OKC Development Services under §41-80 at $200 per property per year, with escalating fees for properties vacant over 5 years. Registration includes contact information, insurance documentation, and quarterly inspection commitments. OKC has identified approximately 12,000 vacant lots and structures, concentrated in near-downtown neighborhoods (east of I-235, north of I-44). The Urban Renewal Authority acquires and redevelops blighted vacant properties. Municipal mowing program addresses non-compliant lots — OKC contractors mow at $200-$500 per mowing cycle, billed to the owner with 15% administrative fee. Persistent nonpayment results in liens collected by Oklahoma County Treasurer through tax sale. Illegal dumping on vacant lots (common problem) carries additional fines of $500-$2,500 per incident. Edmond and Midwest City follow similar rules under their property maintenance codes. Rural unincorporated Oklahoma County has more permissive rules.
