Why is living in storage units illegal?

Living in storage units is illegal primarily because storage facilities are not zoned or built for human habitation and violate building codes, health codes, and safety regulations. Storage units lack basic habitability requirements such as running water, sewage, ventilation, heating, fire exits, and proper electrical systems for residential use, creating unsafe conditions that risk carbon monoxide poisoning, fire, and health hazards. Zoning laws classify storage facilities as commercial or industrial, not residential, so living there violates local ordinances. Lease agreements explicitly prohibit habitation, and violating lease can lead to eviction and legal action. Insurance policies for facilities do not cover residential use, creating liability issues. Safety concerns include lack of smoke detectors, limited egress, and no kitchen or bathroom, leading to unsanitary conditions. Many jurisdictions also consider it trespassing if you stay beyond access hours. While some people attempt it due to housing costs, it is unsafe and illegal, and cities enforce it to protect occupant safety and maintain code compliance for all tenants.
