Plat & Subdivision Approval in Norman, OK - Process & ETJ Authority
Norman exercises platting authority both inside city limits AND throughout the 5-mile Extraterritorial Jurisdiction (ETJ) under 11 O.S. Sec. 47-101 and Norman Code Chapter 19.5. That means subdivisions and lot splits anywhere within the ETJ boundary go through Norman Planning Commission, even though the parcels are outside city limits.
Two paths exist: (1) Lot Split / Minor Subdivision - splitting an existing legal parcel into 2-4 lots with no new public streets, administrative review by Planning staff, typically 14-21 days; (2) Major Subdivision Plat - any larger subdivision, requires preliminary plat approval by Planning Commission, then final plat acceptance by City Council, typically 90-180 days.
Property in the ETJ does NOT pull Norman building permits - those go to Cleveland County. But the lot itself must be platted through Norman if it is being created, split, or replatted. Mortgage and title companies regularly require Norman ETJ-compliant plats for closing.

Plat / Subdivision permit FAQs — Norman, OK
What is Norman ETJ and does it apply to my project?
Norman exercises Extraterritorial Jurisdiction (ETJ) for platting roughly 5 miles outside city limits under 11 O.S. Sec. 47-101. If you are splitting, replatting, or subdividing a parcel within that 5-mile zone, the plat goes through Norman Planning. If you are just building a single house on an existing lot in the ETJ, your building permit goes to Cleveland County, not Norman.
How long does a lot split take in Norman?
A simple lot split (minor subdivision) typically takes 14-21 business days for administrative approval. A major subdivision plat takes 90-180 days because of the Planning Commission and City Council hearing cycles.
