Potomac Property ManagementGreat Falls Estates & Churchill Schools, Flat Fee
Potomac is one of Montgomery County’s most affluent single-family rental markets — sprawling estates near Great Falls National Park and the Congressional Country Club, anchored by the top-rated Winston Churchill High School cluster. The tenant pool skews toward established executives, physicians, and relocating senior professionals who lease before buying. We handle the Montgomery County Bill 15-23 rent cap, the DHCA rental license, and the Maryland §8-203 deposit clock so you don’t have to.
Our Maryland average: 17 days to lease. Our guarantee: 9–12 months or we replace for free (bundle benefit).

Renting in Potomac, Maryland
Potomac sits in the affluent southwest corner of Montgomery County, between the Potomac River gorge at Great Falls and the I-270 corridor. The estate stock near the Congressional Country Club, MacArthur Boulevard, and Potomac Village commands rents well above the county median, and demand is driven by the Winston Churchill High School cluster — consistently among Maryland’s highest-rated — plus proximity to the Bethesda and DC employment cores. Tenants skew toward established executives, Washington-area physicians, diplomats, and out-of-area families who rent a larger home before committing to a purchase.
Two operational realities define Potomac management. First, the Montgomery County rent-stabilization law (Bill 15-23, County Code Chapter 29) caps annual increases on covered units at the lesser of CPI-U + 3% or 6% (5.7% effective July 1, 2025) and requires 90 days’ written notice. The law covers County-licensed units at least 23 years old; a natural-person landlord who owns two or fewer rental units in the County is exempt. We confirm coverage against the unit’s SDAT ‘year built’ record before calculating any renewal. Second, Montgomery County requires a DHCA rental housing license, and the Maryland Department of the Environment lead-paint registration applies to pre-1978 stock — we track both.
Potomac landlords need a manager who knows Montgomery County’s rent-stabilization mechanics, the Maryland Real Property Code, and the high expectations of an estate-grade tenant — not a generalist charging 8–10% of rent that climbs with every renewal. Our flat fee model with full guarantees aligns our incentives with yours: fill the property fast with a screened tenant from the Perfect 10ant System™, draft a compliant lease, track the §8-203 45-day deposit clock, and run the Maryland District Court Failure-to-Pay-Rent process when needed (Preferred and Concierge, for tenants we placed).

What Potomac Landlords Lose Sleep Over
Three operational realities that blindside Potomac landlords without a manager who knows Montgomery County Rent Stabilization (Bill 15-23), the Maryland §8-203 45-day deposit clock, and the Montgomery County DHCA rental license.

Bill 15-23 Above-Cap Increase
Montgomery County’s rent-stabilization law (Bill 15-23, County Code Chapter 29) caps annual rent increases on covered units at the lesser of CPI-U + 3% or 6% — the allowance effective July 1, 2025 is 5.7%. The law covers County-licensed rental units at least 23 years old; a natural-person landlord who owns two or fewer rental units in the County is exempt. Increases require 90 days’ written notice. We confirm coverage against SDAT ‘year built’ data and calculate every renewal compliant from day one.

DHCA License + MDE Lead
Montgomery County requires a DHCA rental housing license with a recurring inspection cycle, and the Maryland Department of the Environment lead-paint registration applies to pre-1978 stock. A lapsed license or an unregistered pre-1978 unit can trigger fines and complicate enforcement of the lease. We track the license renewal and schedule the inspection so neither lapses.

§8-203 Deposit Penalty
Maryland Real Property §8-203 caps a security deposit at one month’s rent and requires the deposit (plus accrued interest at the greater of the U.S. Treasury 1-year yield-curve rate or 1.5%/yr) be returned within 45 days of the end of the tenancy, with an itemized list of any damages withheld. Charging over one month, or failing to return without a reasonable basis, exposes the owner to up to threefold of the wrongful amount plus reasonable attorney’s fees. We track the 45-day clock and the itemization on every tenancy.
Don't let a mishandled deposit trigger a 3× §8-203 penalty.

Potomac Landlord FAQs
Seven answers anchored on Potomac-specific verified facts. Updated May 2026 by the Flat Fee Landlord Maryland team.
Potomac rents span a wide range — a renovated estate near Great Falls or the Congressional Country Club prices very differently from a townhome near Potomac Village — and the band moves with the market, so a fixed number ages out fast. The Flat Fee Landlord Maryland team provides a free Potomac rental analysis using block-level comparable data. Owner-set asking rents in Potomac often miss because owners benchmark against the broader Montgomery County average rather than the specific Churchill-cluster and Great Falls submarkets, which carry a meaningful premium.
It depends on the unit. Bill 15-23 (County Code Chapter 29) covers County-licensed residential rental units that are at least 23 years old and caps the annual increase at the lesser of CPI-U + 3% or 6% — the allowance effective July 1, 2025 is 5.7%. Newly built units (offered for rent less than 23 years) are exempt, and a natural-person landlord (or a trust/estate of a decedent) who owns two or fewer rental units in the County is also exempt. Potomac is unincorporated Montgomery County, so it falls under the general county rule (no separate municipal regime). We confirm your unit’s status against its Maryland SDAT ‘year built’ record before calculating a renewal, and any increase requires 90 days’ written notice.
Potomac’s tenant pool skews toward established executives, Washington-area physicians and attorneys, diplomats, and out-of-area families relocating into the Winston Churchill High School cluster who rent a larger home before buying. The estate and large-lot stock near Great Falls, MacArthur Boulevard, and the Congressional Country Club draws longer tenancies than a typical suburb because these households tend to settle for multiple school years. That stability is a strength — paired with disciplined screening it produces clean, long renewals.
Yes — because Potomac is unincorporated Montgomery County, residential rentals require a Montgomery County DHCA rental housing license with a recurring inspection cycle, and a Maryland Department of the Environment lead-paint registration applies to pre-1978 stock. A lapsed license or an unregistered pre-1978 unit can trigger fines and complicate lease enforcement. We track the license renewal and schedule the inspection so neither lapses. Verify the current fee and inspection cycle with Montgomery County DHCA.
Maryland Real Property §8-203 caps a security deposit at one month’s rent per dwelling unit and requires the landlord to return it — plus simple interest at the greater of the U.S. Treasury 1-year yield-curve rate or 1.5% per year — within 45 days after the end of the tenancy, along with an itemized list of any damages withheld. Charging more than one month, or failing to return without a reasonable basis, exposes the owner to up to three times the wrongful amount plus reasonable attorney’s fees. We hold deposits per §8-203 and track the 45-day clock and itemization on every tenancy.
Percentage managers charge 8–10% of monthly rent — and on a high-rent Potomac estate that fee is steep and climbs every time your rent rises. Flat Fee Landlord pricing starts at $139/mo (Basic, annual billing); Preferred is $179/mo and Concierge is $349/mo (annual billing). The flat fee never increases with rent, so the savings are largest exactly where Potomac rents are highest — a single Potomac estate can save many thousands of dollars a year versus an 8–10% percentage manager, and the gap compounds at every renewal. Use the Flat Fee Landlord quote builder to model Basic, Preferred, or Concierge against your actual rent.
Maryland Failure-to-Pay-Rent cases are heard in the District Court of Maryland. Under the framework updated by the Renters’ Rights and Stabilization Act of 2024, the landlord must give the tenant at least 10 days’ written notice of intent to file before filing the complaint; the court then issues a summons and holds a trial, and if the landlord prevails a warrant of restitution is issued (warrant timing extended to 7 business days under the 2024 law). Eviction coordination is a bundle benefit on our Preferred and Concierge plans for tenants we placed — we coordinate notices, the District Court filing, and scheduling while filing fees and court costs pass through to the owner at cost. Basic does not include eviction coordination, and the bundle benefit applies only when Tenant Placement + Property Management are purchased together.
