Franklin Township, PA Accessory Structures: ADU Rental Restrictions (2026)

7 draws a bright line for every additional dwelling unit the Township permits under § 27-1712, whether it's tucked inside the principal house or built as a detached accessory unit: it may only be used for long-term occupation, and short-term rental use is not allowed. The code doesn't set a minimum number of nights for what counts as long-term, but the prohibition is absolute rather than a cap, so there is no permit tier or registration path that authorizes short-term use of an ADU here.

2, the number of ADUs a lot may add depends on lot size, a detached ADU triggers land development review and needs its own street address, and every ADU still needs a zoning permit and a building permit under the current Uniform Construction Code. 2 already requires the property owner to live on site, the short-term-rental ban forecloses the two most common ADU-to-STR conversions: renting the ADU nightly while the owner lives in the main house, and renting the main house nightly while the owner occupies the ADU.
