Maryland’s priciest zip codes stretch from Chesapeake Bay enclaves to DC-adjacent suburbs, with Gibson Island as price leader and a cluster of pricey Bethesda locations joined by Howard County markets known for large estates.
Key Takeaways
- Gibson Island’s 21056 is Maryland #1 most expensive zip code at a $3.15M median, followed by Annapolis’ 21405 at $1.82M

2025 further underscored the wealth patterns of Maryland’s luxury real estate market: Chesapeake Bay waterfront communities and western D.C. suburbs, where large-lot homes, established neighborhoods and access to top job hubs continue to support premium pricing.
Western Howard County’s estate belt also features prominently, while Baltimore County’s Stevenson holds its spot among classic suburban standouts.

While no other Maryland made our ranking of the top 100 most expensive zip codes in the U.S., the upper tier of Maryland’s real estate also features Annapolis’s 21405 at #2, followed by Bethesda and Potomac zips, reflecting persistent demand near major employment centers and lifestyle amenities.

Top 10 Most Expensive Zip Codes in Maryland in 2025
#1. Gibson Island 21056, Anne Arundel County
Median Sale Price: $3,150,000
Gibson Island’s 21056 clearly separates itself from the rest of Maryland’s luxury market, ranking first statewide and #32 nationally. With pricing far ahead of the second-place zip, the private Chesapeake Bay community stands out for its limited inventory, large estates and coastal setting. Its performance alone was enough to push Anne Arundel County to the top of Maryland’s ranking, underscoring how concentrated the state’s ultra-luxury market remains.
#2. Annapolis 21405, Anne Arundel County
Median Sale Price: $1,825,000
Technically, the state’s capital took second place with zip 21405 reaching $1.85 million. However, Annapolis’ 2025 price peak was actually located in the exclusive Sherwood Forest community, the pricey gated enclave five miles from downtown Annapolis. This proximity to regional employment hubs paired with the community’s lifestyle appeal, including high-end golfing, continues to command premium prices. Anne Arundel County’s presence in both of the top two spots highlights the outsized role waterfront-adjacent communities play in setting Maryland’s pricing ceiling.
#3. Bethesda 20816, Montgomery County
Median Sale Price: $1,400,000
Bethesda’s 20816 led Montgomery County real estate in 2025, one of three zip codes in the city to rank among Maryland’s 25 priciest. The exclusive zip code covers quiet residential neighborhoods like Brookmont, Westgate, Westmoreland and Woodacres, known for leafy streets and proximity to parks and nature. The riverfront zip also enjoy close proximity to Washington, D.C., generating consistent demand from upper-income buyers which has kept prices firmly in seven-figure territory
#4. Bethesda 20817, Montgomery County
Median Sale Price: $1,350,000
Another Bethesda entry, zip 20817 reinforced Montgomery County’s dominance in the upper tier of Maryland’s housing market.

Together with neighboring Bethesda zip 20816, Cabin John zip 20818, Potomac zip 20854, plus zip 20815 in the Chevy Chase, Chevy Chase Village, Martins Additions and North Chevy Chase area among, it forms a dense cluster of high-priced markets anchoring the state’s western suburbs.
#5. Potomac 20854, Montgomery County
Median Sale Price: $1,310,000

As such, the area continued to attract buyers seeking space without sacrificing proximity to major employment centers in 2025 as well.
#6. Glenelg 21737, Howard County
Median Sale Price: $1,280,000
Glenelg’s 21737 led Howard County in 2025, reflecting the strength of the county’s western corridor. Once firmly agricultural, nowadays the area has semi-rural character, defined by continued development of expansive, high-end homes on large lots.

#8. West Friendship 21794, Howard County
Median Sale Price: $1,163,000
West Friendship’s 21794 continued Howard County’s strong showing, posting a median sale price of $1.16 million. Its pricing closely tracked nearby Glenelg and Clarksville, reflecting similar housing profiles and buyer demand. Price verticality in West Friendship continues to be fueled by its housing stock, characterized by sizeable single family homes on large lots, as well as its positioning on the Baltimore-Washington corridor, with half of households here owning three or more vehicles.
#9. (tie) Cabin John 20818, Montgomery County
Median Sale Price: $1,100,000
Linking Potomac’s top-tier real estate with Bethesda’s leading luxury housing, Cabin John’s 20818 also connects linking the Bethesda–Potomac pricing core with the rest of Montgomery County’s high-end real estate sector.

#9. (tie) Stevenson 21153, Baltimore County
