Unlike most large cities in the United States, Houston does not have traditional zoning laws that strictly separate residential, commercial, and industrial areas. This means houses, offices, and businesses can sometimes exist very close to each other. Because of this, it is common to see a restaurant or store next to a residential neighborhood. The city instead uses other regulations like development rules and deed restrictions. This system makes Houston’s urban layout quite unusual compared to other major cities.
There Is a Large Underground Tunnel System

Beneath downtown Houston is an extensive underground tunnel network that stretches for several miles. These tunnels connect office buildings, restaurants, shops, and hotels. They allow people to move around comfortably during Houston’s hot and humid weather. Many workers use the tunnels during lunch breaks to access different dining spots. The tunnel system is mostly used on weekdays by people working in the downtown area.
