Are ADU’s allowed in Oklahoma City?

[Kolbey Pruitt]

I have ran some searches and cannot find the Oklahoma City Law pertaining to Additional Dwelling Units. I see neighborhoods that have them, However. Does anyone know the requirements?

You do have to be zoned at least R2 (in Oklahoma City that is two dwelling units on one lot). Last time I talked to the city about this issue, they were very unwilling to have ADUs in single family zoning.  I was advised that I could apply for exemption but to not hold my breath. To the extent that they are present in single family zoned areas, it is likely they were grandfathered in a number of years ago.  Be aware that should a grandfathered dwelling unit be lost to a catastrophe, it most likely cannot be replaced.  In some of the historic areas we'll see additional garage apartments that exceed the approved zoning.  If those are lost, they will not, generally speaking, be approved for replacement.  Though not necessarily a deal-breaker, one would want to be aware of the potential for lost income.
