Frequently Asked Questions
What was Tulsa's 2020 zoning reform and how does it affect me?
Tulsa adopted a comprehensive new Zoning Code in 2020 that replaced a decades-old framework. Key changes affecting homeowners: ADUs are now allowed by-right in all RS zones (no longer requires conditional use permit), parking minimums were reduced in mixed-use and transit-adjacent areas, and new form-based RS-4 and MX zones were created for compact development. If you want to build a backyard cottage or convert your garage to a rental unit, the new code makes it easier than before.

Yes. Since the 2020 zoning reform, ADUs are allowed by-right in all RS (single-family residential) zones in Tulsa. Maximum size is typically 850 sqft.
