This distinction is critical for homeowners and ADU contractors working in the area, as it means all permits, inspections, and zoning approvals must go through Harford County's Department of Planning and Zoning.
Before breaking ground on any ADU project in Jarrettsville, experienced ADU contractors must navigate Harford County's specific zoning codes. Many properties in and around Jarrettsville are zoned Agricultural (AG) or Rural Residential (RR), which can affect the type and size of ADU that is permitted. Key regulatory considerations include:
