Short-term rentals (STRs), often referred to as "vacation rentals," are legal in New Castle City, Delaware, but are subject to specific regulations administered by the New Castle County Department of Land Use. Property owners must register their rental properties, including STRs, ensuring compliance with local zoning codes and health and safety standards. STRs are thriving predominantly in residential areas where properties such as single-family homes and townhouses are often rented out, largely catering to tourists visiting the area's attractions, given its proximity to historical sites and natural beauty. The overall market environment tends to favor vacationers, though there is some demand from business travelers. The recent enforcement approach to STR regulations has been described as relatively lenient, with ongoing discussions around potential legislative changes that could influence the market further.
