Bill Overview

Analyzed Economic Effects

2 provisions identified: 0 benefits, 0 costs, 2 mixed.

Mobile-home residents can install portable ACs

Beginning June 11, 2026, people who rent space in mobile or manufactured home parks can install portable cooling devices. The park cannot ban these units, including U-shaped models that hang over the windowsill. The park can say no only if installation would break building, state, or federal law, violate the maker’s written safety rules, cause unreasonable damage, or need more power than the park or lot can provide.

Renters can install portable ACs, with rules

Beginning June 11, 2026, renters can install portable cooling devices in their homes. The rule covers window and floor models and portable heat pumps. Landlords cannot charge a fee for using, installing, or inspecting your device. They can charge rent if you rent a device from them, and recover for damage, including from your deposit. Landlords can say no if a working heat pump is already installed, if codes or the maker’s safety rules would be broken, if it would cause unreasonable damage, or if the electrical service cannot handle it. Extra limits apply to window units: they cannot block an escape window, stop the window from locking, need damaging brackets, be unsecured from falling, or go against the landlord’s insurance (with written proof). Landlords may require proper drainage and can check the installation; you must give 2 days’ notice before installing a window unit. If window units are restricted, the lease must explain the rules. Landlords are not liable for injuries or damage caused by a tenant’s device, and they are not responsible for power interruptions they did not cause.
