What the August 4, 2026 change does
- Reverts over 300,000 single-family lots from R-CG back to R-C1 or R-C2.
- Restricts row-house and townhouse development on mid-block interior lots.
- Reduces max principal units on remaining R-CG parcels from 4 to 3.
- Adds new height, coverage, and setback constraints on R-CG parcels.
Who is grandfathered under the old blanket rezoning?
Property owners who obtained an approved development permit, building permit, or subdivision application under R-CG, R-G, or H-GO before August 4, 2026 keep those rights. Property owners who submitted an application before April 8, 2026 (the first reading date) are also protected. Parcels that were rezoned through an approved rezoning application after August 6, 2024 (the original blanket rezoning date) retain their R-CG designation.

What this means for landlords and investors
The MLI Select 5-unit minimum is now much harder to hit through infill on standard inner-city lots. Existing 4-plex, 6-plex, and small apartment projects already permitted retain their value. Future small multi-family opportunities are concentrated in parcels with existing R-CG, R-G, M-1, or M-2 designations that were unaffected by the repeal, plus discretionary rezoning applications on a case-by-case basis. Always verify zoning before offering on a lot for redevelopment.
