Overview: Are Short-Term Rentals Allowed in New Castle, Delaware?

Short-term rentals are currently in a state of regulatory transition in New Castle, Delaware. The city has implemented a 6-month moratorium on new STR licenses while the Planning Commission develops comprehensive regulations. In the broader New Castle County (unincorporated areas), short-term rentals are effectively prohibited in residential districts and only permitted in commercial zones. Existing tourist home operations in the Historic Districts remain legal but face upcoming regulatory review.

The regulatory environment is evolving rapidly, with the city working toward new ordinances by August 2025. Investors should note that the historic character of New Castle and ongoing preservation efforts significantly influence STR policy.
