More of my buyers are moving a parent in, or an adult kid back home, or both. They want a separate entrance, a full bath on the main level, or a basement with its own kitchen. Those homes exist in Rockville, but you won't find them by searching bedrooms and baths alone. I'm James Buckley, Canopy Property Group at eXp Realty, and here's how I look for them.
There's no single definition in the MLS. It can mean a finished walkout basement with a bedroom, bath, and kitchenette. It can mean a main-level bedroom and full bath. Sometimes it's a separate apartment over a garage. I read the listing remarks and photos closely, and I ask the listing agent questions before we tour.
Montgomery County allows accessory dwelling units in many single-family zones, I believe, with registration and a license. The City of Rockville has its own zoning code, so the rules inside city limits can be different. Before you buy with an ADU plan, check the lot's zoning and talk to the city or county permitting office.
Split levels and ramblers in Twinbrook, Woodley Gardens, College Gardens, and Potomac Woods often have a lower level with its own entrance. Larger homes in Fallsgrove and King Farm can have main-level bedrooms. I can't promise a certain floor plan in any neighborhood, but I know where to look.
It varies a lot. Across the Rockville area the median sale was $650,000. Homes at $1M and up had 225 sales at a $1.28M median and sold in 8 median days (Bright MLS, Oct 2026). Larger homes with a separate suite often sit near or above that line.
It can widen your buyer pool, since some buyers want rental income and others want space for family. If it was added without permits, though, it can hurt. I check the permit history before you buy so you're not inheriting a problem.
