Doylestown Borough does not currently acknowledge accessory dwelling units (ADUs) as self-sufficient dwellings on a parcel with a main house. According to the Zoning Director, the Borough receives increasing inquiries about additional living spaces for multi-generational purposes. Guest houses or suites that are separate from a main house and include a bedroom, bathroom, and coffee bar may be considered if they meet zoning requirements, but properties must still meet minimum land size requirements. The Borough is revisiting its comprehensive plan, which could include discussion of ADU accommodations. Garage conversions and units above garages generate the most interest. PA MPC (Act 247) allows municipalities to zone for ADUs but does not mandate them. No statewide ADU mandate exists in Pennsylvania.
