HB1497 adds a new provision to Maryland law that directs Charles County to establish an annual limit on rent increases for rental units occupied by seniors. The statute defines several operative terms and confines the new requirement to Charles County.
For housing professionals and local policymakers, the bill matters because it shifts the mechanics of rent-stabilization policy to the county level while tying any allowable increases to an objective inflation measure. The provision is narrowly targeted — it is limited to units occupied by seniors — but it raises practical questions about implementation, enforcement, and impacts on owners and the local rental market.
At a Glance
What It Does
The bill requires Charles County to establish an annual rent increase limit for units occupied by a senior and caps that limit at no more than the Consumer Price Index for All Urban Consumers for the Washington metropolitan area (or a successor index). It adds a statutory definition of base rent and defines “senior” by reference to the age for full Social Security retirement benefits.
Who It Affects
Directly affected parties include Charles County government (which must adopt the limit), rental property owners and managers with senior tenants, and seniors who rent in the county. Indirectly it will affect housing advocates, property insurers, and local housing market analysts tracking rent-setting behavior.
Why It Matters
By tying a local rent cap to a regional CPI, the bill creates a predictable ceiling for allowable annual increases to protect some fixed-income renters, while leaving the exact limit and enforcement approach to county officials. That combination of a statutory ceiling with local implementation authority is likely to shape both county ordinance drafting and landlord responses in Charles County.

What This Bill Actually Does
HB1497 inserts a new section into the Real Property Article that, at its core, obligates Charles County to set an annual limit on rent increases for units occupied by seniors. The bill supplies three working definitions — base rent, the CPI reference, and senior — and then imposes a single substantive duty on the county: establish an annual rent-increase limit that is no greater than the specified CPI measure.
Operationally, the statute leaves the mechanics of ordinance design to county officials. The county must decide how to calculate and publish the limit each year, whether to apply it only at lease renewal or also during a lease term, how to treat month-to-month tenancies, and how landlords should document compliance.
The law does not include an enforcement mechanism, administrative penalties, private right of action, or criminal penalties — it simply requires the county to create the limit.The definitions in the bill matter in practice. “Base rent” is the rent under the current lease, which frames increases relative to an existing contractual amount rather than to a historical benchmark. “Senior” is tied to the age required for full Social Security retirement benefits, a moving threshold that changes by birth cohort; that design makes the population eligible for the protection variable over time. The CPI specified is the regional Washington metropolitan index, which may diverge from local housing cost trends in Charles County and thus affect how restrictive the cap is in practice.Because the statute applies only in Charles County and becomes effective October 1, 2026, county officials will have a defined window to draft and adopt implementing regulations or an ordinance.
The lack of statutory detail about exemptions (for new construction, subsidized housing, small landlords), enforcement, or landlord cost recovery creates practical gaps that the county must resolve when it writes implementing rules.
The Five Things You Need to Know
The bill adds a new statutory provision at Article – Real Property §8–209.2 specifically applicable only to Charles County.
It defines “senior” as an individual who has reached the age required to receive full Social Security retirement benefits (the full-retirement age varies by birth year).
The allowable annual increase is capped at no greater than the Consumer Price Index for All Urban Consumers for the Washington metropolitan area, or any successor index.
“Base rent” is defined as the rent in effect under the current lease, meaning increases are measured relative to the tenant’s current contractual rent.
The act takes effect October 1, 2026, creating a clear deadline for Charles County to adopt an implementing rent-increase limit.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Definitions — base rent, CPI, rent increase limit, senior
This subsection supplies the statutory vocabulary the county will rely on. Defining base rent as the current lease rent means any allowed increase is measured from what the tenant already pays rather than from an initial or historically low rent. The CPI choice points the county to a specific inflation measure — Washington metro CPI — and the senior definition ties eligibility to the federally determined full Social Security retirement age, which changes by cohort. These choices will influence who qualifies and how binding the cap is.
Geographic scope — Charles County only
The provision explicitly limits application to Charles County. That leaves other Maryland counties unchanged and places the burden of ordinance drafting, notice, and enforcement on the county government rather than the state. Local specificity also means the county must reconcile the regional CPI reference with local housing conditions when it sets the annual limit.
County duty — establish annual rent increase limit no greater than CPI
This is the operative mandate: Charles County must establish an annual rent-increase limit for rental units occupied by seniors and that limit cannot exceed the specified CPI. The bill does not prescribe the format of the limit (percentage, formula, or index adoption), the timing of adoption each year, or enforcement steps; it simply bounds the maximum allowable increase. That grants flexibility but also requires the county to fill in many implementation details.
Effective date
The act becomes effective October 1, 2026, giving the county a finite period to adopt any ordinance, administrative guidance, or processes needed to operationalize the new requirement. Because the statute lacks transitional rules, the county must decide whether the first published limit will apply to leases and renewals occurring after that date or to other categories of tenancy.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Low- and fixed-income senior renters in Charles County — they gain a predictable ceiling on annual rent increases tied to inflation, reducing the risk of sudden unaffordable hikes at renewal.
- Senior-serving nonprofits and legal aid organizations — the policy can stabilize caseloads by reducing emergency displacement among older renters and provide a clear advocacy target.
- Long-term senior tenants in market-rate housing — tenants with long tenancies will see increases measured from their existing lease rather than from market resets, which can preserve affordability for those already in place.
Who Bears the Cost
- Private landlords and property managers in Charles County — they face a capped ability to raise rents for senior-occupied units, potentially constraining revenue needed for maintenance, taxes, and debt service.
- Small-scale owners of senior-occupied units — smaller landlords with thin margins may feel the cap more acutely, and some may choose to convert uses, sell, or exit the rental market.
- Charles County government and staff — the county must draft the ordinance, determine calculation and notice processes, monitor compliance, and potentially defend or enforce the limit without dedicated funding from the statute.
Key Issues
The Core Tension
The bill attempts to reconcile two legitimate goals — protecting seniors on fixed incomes from sudden rent shocks and preserving landlords’ ability to cover operating costs — by imposing a maximum tied to regional inflation while leaving implementation to the county. That compromise forces a trade-off: stronger, prescriptive rules would better protect tenants but reduce owner flexibility and might suppress investment, while a lighter, county-driven approach preserves landlord discretion but risks uneven protection and enforcement.
The bill sets a ceiling but leaves most mechanics to the county. That design balances a clear statewide boundary with local implementation flexibility, but it also creates three practical voids: enforcement, exemptions, and application timing.
The statute contains no enforcement mechanism or remedy. It does not create a private right of action, specify administrative penalties, or authorize inspections — all of which forces the county to decide whether violations will be handled through existing ordinances, newly created administrative processes, or the courts.
The absence of explicit exemptions (for new construction, owner-occupied dwellings, subsidized units, or short-term rentals) will require the county to make policy choices that materially affect both the statute’s reach and landlords’ business models.
Another complexity is the choice of index and the definition of “senior.” Using the Washington metropolitan CPI ties the cap to a regional inflation measure that may lag or outpace Charles County’s housing-specific cost trends; that could make the cap either looser or stricter than a locally calibrated alternative. Defining a senior by full Social Security retirement age introduces a cohort-based eligibility threshold that shifts over time, complicating administration and outreach.
Finally, defining base rent as the current lease rent makes the protection relative rather than absolute; landlords can still rebase rents when leases expire unless the county ordinance specifies otherwise, creating a loophole that could blunt long-term protective effects.
