Open questions
- Ordinance text not yet verified against the municipal code. The primary source PDF (hpboro.com) returned HTTP 403 to automated fetch, and the Wayback Machine mirror could not be retrieved in this session. Secondary web search results (ecode360.com/10613114 and related pages, and third-party summaries) suggest the current codified cap may be a flat 5% ceiling on the 60-month CPI average (using a simple average of NYC and Philadelphia CPI figures) and that the ordinance was last substantively amended December 20, 2022, but none of this could be confirmed with an exact quoted sentence, so it is NOT included as verified data above.
- The 30-day notice figure came from a search-engine summary of the Borough's rent-control webpage, not a verbatim ordinance quote; treat as unconfirmed.
