Townhouses as Family‑Friendly Urban Housing

Developers are reviving attached single‑family townhouses to offer families the combination of private space and walkable urban life. The resurgence is colliding with century‑old zoning, floor‑area, and fire‑safety rules that make building new townhouse blocks difficult or expensive. — If scaled, townhouse revival would change urban housing mixes, affecting family retention, neighborhood density without tower construction, and the focus of zoning reform debates.
