What’s the 511

511 N Broad · Philadelphia

Who to contact

Building management at this time is Onyx Capital Management (since January 1, 2026). The association board sets policy; management runs the building; this site is unofficial neighbor notes.

Who does what

  • Association board — oversight of building and management: budget, rules, and vendors. Packets and minutes live on the Resident portal, not on this site.
  • Building management — Onyx Capital Management. Day-to-day work goes through the Resident portal. The Building Management Emergency Phone Number is for emergencies only.
  • What’s the 511 — neighbor how-to and newsletters. Not official notice. Corrections: WhatsThe511NBroad@gmail.com.
  • Owners — maintain the unit (windows included). Contact building management for shared building issues; file common-area tickets in the Resident portal. Construction: tell management first — Owning your unit.
  • Renters — landlord first for the unit, fobs, and mailbox. The owner talks to building management for common-area repairs.

City vs building

Not every problem belongs to building management. Save the right number before you need it.

Official papers

Bylaws, rules, meeting packets, assessments, and notices live on the Resident portal — this site doesn’t republish them. Owners should have an account. Renters: ask your landlord what you need from that portal.
