South Brunswick rent control: maximum rent increase (2026)

Middlesex County — Chapter 78, Article V, Rent Control. Full ordinance text ↗

Summary

Cap formula
DCA survey formula: Rent Adjustment (RA) = (Y + Y1 + Y2 + Y3 + Y4) * 5, where Y is the percent change in the applicable CPI subindex for the current year and Y1–Y4 are the percent changes for each of the four previous years. This is an unusual multi-year formula that could not be verified against the ordinance text; it is copied as-is from the DCA survey and should not be treated as a confirmed computation method (a divide-by-5 average, rather than multiply-by-5, would be the more typical construction of such a formula, but this has not been confirmed).
