A neighborhood and homeowners association name that Montgomery County's plat records do not contain — the homes behind it are recorded under a different subdivision entirely.
Start with the fact that changes how you search: there is no Montgomery County subdivision or plat named Potomac Falls. The association is real and the name is used in conversation and in listings, but a deed, a plat and a title search here are filed under another name. A buyer who types Potomac Falls into the county land records finds nothing, and concludes either that the neighborhood does not exist or that they are searching the wrong county. Neither is true. What follows separates the association's account of itself from what the county record shows, and flags the one boundary question still open as of August 2026.
No recorded Montgomery County subdivision carries the name Potomac Falls, so a search of the plat index or the land records by that name returns nothing. The facts the association gives about itself line up with the recorded Great Falls Estates plats: the same W.C. & A.N. Miller developer lineage, the same 1959–60 starting point, the same RE-2 two-acre pattern — and Cripplegate Road, one of the streets the name is used for, falls entirely inside the Great Falls Estates plat. The accurate way to describe a house here is a home recorded under the Great Falls Estates subdivision, in a neighborhood known as Potomac Falls. That distinction decides which plat your surveyor pulls, which subdivision your title work runs against, and which recorded sales an appraiser can use as comparables.
The association's own account is that Potomac Falls was established in 1960 by W.C. and A.N. Miller across roughly 800 acres, with more than 200 homes on a two-acre minimum, and 262 home sites today. Those figures come from the association rather than from county records, and they describe a membership area rather than a platted subdivision — quote them that way. The open question, as of August 2026, is the association's mapped boundary against the Great Falls Estates plat: whether the two are coextensive, or whether the association covers only part of it, or reaches beyond it. Nothing in the public record settles that. Before writing an offer, ask the association for its current boundary map, dues schedule and governing documents, and whether membership runs with your lot or is voluntary. Then read whatever declaration is recorded against that lot — that document, not the neighborhood name, is what binds a buyer.
Potomac Falls is also a census-designated place in Loudoun County, Virginia, near Sterling and Cascades some thirty miles away, and search results blend the two constantly. They share nothing that matters to a transaction: different state, county, school system, recordation and transfer tax treatment, housing stock and price basis. The Maryland neighborhood sits in ZIP 20854 with a Potomac mailing address in Montgomery County. If a listing alert or market report says only Potomac Falls, verify the county before comparing it to anything.
Parcels here are predominantly in sewer service category S-6 under Montgomery County's Comprehensive Water Supply and Sewerage Systems Plan: no community sewer service planned within the plan's ten-year scope or beyond, so development uses private systems. Do not underwrite on a future connection — a category change is a formal proceeding filed with the Department of Environmental Protection on a quarterly review cycle, not a request. The gating step for a new or replacement house is establishing a sewage disposal area with room for an initial drainfield and a reserve, and the water table test that precedes it runs only in a declared wet season, typically February 1 to April 15. As of August 2026 the Department of Permitting Services reports the 2026 season closed and applications no longer accepted, which can push a study a full year; DPS Well and Septic is at 240-777-0311. That drainfield land leaves the buildable envelope before the RE-2 lot coverage cap of 25 percent under the standard method is applied.

Addresses in this area are served by Potomac Elementary School, Herbert Hoover Middle School and Winston Churchill High School in Montgomery County Public Schools. Assignment is made by address rather than by neighborhood name, and MCPS boundaries are periodically restudied, so confirm the current assignment for the exact address through the MCPS boundary lookup rather than from a listing sheet or this page. Two confirmations belong in the same pass: the plat and legal description pulled from county land records under the recorded subdivision name, and the association's current documents and boundary map.
