Summary

Baltimore County requires landlords of three or more rental units to give 60 days' written notice before any rent increase takes effect, but only during a declared eviction moratorium or public health emergency and for 90 days after it ends. The notice must go by First Class mail and be posted on the unit's door under County Code Article 35, Title 3.

These county ordinances apply to unincorporated areas of Baltimore County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

(a)Restrictions. During an emergency and for a period of 90 days after the expiration of an emergency, a landlord may not charge, collect, or demand from a tenant an increase in rent until 60 days after the landlord gives the tenant written notice of the rent increase.(b)Posting and contents of notice. A written notice of rent increase required under this section must be mailed to the tenant by First Class mail and posted on the door of the dwelling unit and contain the following:(1)The amount of rent preceding the effective date of the proposed rent increase, the amount of rent proposed after the rent increase takes effect, and the percentage increase of the rent;(2)The effective date of the proposed rent increase; and(3)Any other information the landlord deems useful in explaining the rent increase.

Full Breakdown

Section 35-3-402 applies during an "emergency," defined in Section 35-3-401 as a national or statewide eviction moratorium lasting at least 30 days or the COVID-19 Catastrophic Health Emergency the Governor declared on March 5, 2020, and for 90 days after that emergency expires. During that window, a landlord who owns, manages, or leases at least three residential units cannot charge, collect, or demand an increased rent from a tenant until 60 days after giving written notice of the increase. The notice must be mailed by First Class mail and posted on the door of the dwelling unit, and it must state the current rent, the proposed new rent and the percentage increase, and the effective date of the change.

Section 35-3-403 caps how much that increase can be during the emergency window: no more than 3% at lease renewal for any tenant who was a party to the original lease, even if notice went out before the emergency began. The same section bars landlords from reporting rent delinquency to a credit bureau during the emergency period. Tenant fee protections run alongside the notice rule: Section 35-3-404 bars late fees, court fees, or payment processing fees during the emergency if the tenant shows the emergency affected their ability to pay.

Section 35-3-405(c) ties enforcement to licensing: before the Director of Permits, Approvals, and Inspections can issue a rental license under Article 35, Title 6, the applicant must receive a copy of these requirements and agree to them in writing.

Violations & Fines

The subtitle sets no separate fine for a missed notice. Instead, Section 35-3-405(c) makes compliance a gate to licensing: before the Director of Permits, Approvals, and Inspections issues a rental license, the applicant must receive a copy of these requirements and agree to them in writing. A tenant charged an increase without the required 60-day notice, or above the 3% renewal cap, can raise the shortfall as a defense against the higher rent, with the county's Code Enforcement powers backing ongoing noncompliance.

Frequently Asked Questions

Does Baltimore County require notice before every rent increase?
No, only during a declared emergency. Section 35-3-402 requires 60 days' written notice before a rent increase, but only while a national or statewide eviction moratorium of at least 30 days, or the COVID-19 Catastrophic Health Emergency, is in effect, and for 90 days after it ends. Outside that window, the subtitle does not impose a separate notice requirement.
How much can my Baltimore County landlord raise my rent during a declared emergency?
No more than 3% at lease renewal, under Section 35-3-403(a), for any tenant who was already a party to the original lease, even if the landlord sent notice before the emergency started. The same section bars the landlord from reporting any related rent delinquency to a credit bureau while the emergency and its 90-day tail run.
What must a Baltimore County rent-increase notice include?
Under Section 35-3-402(b), the landlord must mail the notice by First Class mail and post it on the dwelling unit's door, and it must state the current rent, the proposed new rent, the percentage increase, and the effective date the increase takes effect. The landlord may add any other explanation they find useful.
