Historic review applies to some blocks
Norristown's Heritage Action Plan describes a compact county-seat fabric of brick rowhouses and twins in the West and Central historic areas, with the Schuylkill River and courthouse district as anchors. For a parcel in a municipal historic district, publicly visible exterior permit work goes through the Historical Architectural Review Board. If an empty house needs a new porch or facade, confirm whether your address is covered before you pay for plans. The board's review concerns publicly visible exterior work, so interior repairs are a separate matter. Ask before you assume either way.
