Aerial imagery: Esri World Imagery. Geocoding: U.S. Census Bureau, with OpenStreetMap as a fallback. Imagery is the most recent available for your area and may predate recent work. Drag the footprint to move it, pull the corner to resize, use the round handle or the rotate buttons to line it up with your house. Scale is derived from the image bounds, so the dimensions shown are real feet — but this is a planning sketch, not a survey.
Your addition
Size it on the aerial, then set the rest here.
A planning range for Maryland, not a quote. Additions start with zoning — setbacks, lot coverage and height limits get reviewed before a building permit is issued — so the real number comes after a free on-site walkthrough. HVAC, electrical and plumbing are performed by licensed trade partners.
