A town or city can change its short-term rental rules after you start renting your Pennsylvania property. If your rental was legal before new zoning rules took effect, it may qualify as a lawful nonconforming use. This means the rental may be “grandfathered” under the newer rules and allowed to continue.
When your rental may qualify as a nonconforming use
Grandfathered status is not automatic just because you rented the property before local rules changed. As the owner, you generally must show that the rental existed and was legal before the new restriction took effect.
Permits, licenses, rental agreements or booking records may help show when the short-term rental began. The zoning rules in place at that time also matter. Rental activity that was already prohibited generally does not gain protection when a town later adopts clearer restrictions.
What can affect grandfathered status?
A lawful nonconforming use may continue, but that protection has limits. Local rules may address:
- How long the rental can go unused before it is treated as discontinued
- Whether changes or expansions need local approval
- Whether existing rentals must meet registration or licensing rules
A break in rental activity does not always mean you lose grandfathered status. However, local rules may set a period of nonuse that creates a presumption that you intended to abandon the rental. You may then need evidence showing that you intended to continue the use.
Under Pennsylvania’s natural expansion doctrine, some grandfathered uses may grow or change without losing that status. Local governments can still place reasonable limits on that growth.
Why the original zoning rules still matter
Pennsylvania’s 2019 Slice of Life decision shows why the wording of local zoning rules matters. The state Supreme Court found that the short-term rental at issue did not qualify as a permitted single-family use because the ordinance required occupants to form a “single housekeeping unit.” The ruling did not create a statewide ban on short-term rentals in residential areas.
Clarifying your rental’s status before making changes
Whether your rental is grandfathered may depend on older zoning rules, past rental records and later changes to the property. If those details are unclear, legal guidance can help you review the property’s history and local rules and understand how newer restrictions may affect your rental plans.
