Oakmont‑based Chelsea Building Products is converting a 228,000‑sq‑ft former Westinghouse site in Westmoreland County with roughly $20M, promising new manufacturing capacity and jobs.

A 40‑unit affordable apartment complex in Penn Hills has opened and officials say all units are already leased. The project used tax‑credit equity and county funds and a second phase is planned.
