Montgomery County MD rental license requirements explained

Last updated 2026-07-24

What rental properties need a license in Montgomery County?

Montgomery County's rental licensing program covers nearly every residential rental property in the county. If you rent out a single-family home, a duplex unit, a condo, a townhouse, or an apartment, you need a license ^[1]. The county defines a rental housing facility as any structure or part of a structure that is rented or offered for rent for residential use. That includes properties you rent by the week, month, or year. Owner-occupied properties where you rent out a room or basement unit still count as rental housing and still require licensing ^[1]. A handful of exemptions exist, but they're narrow. Hotels, motels, hospitals, nursing homes, and similar transient or institutional facilities are exempt. So are dormitories operated by educational institutions. Most single-family home landlords and small multifamily owners don't qualify for any exemption and must go through the full licensing process ^[1]. The law applies whether you own one rental unit or fifty. It doesn't matter if you're an individual landlord, an LLC, or a property management company acting on behalf of an owner. The license requirement is property-based, not owner-based. Understanding what rental rights tenants have helps you prepare for the questions your future tenants will ask during showings and lease negotiations.

How do you apply for a rental housing license?

You apply for a Montgomery County rental housing license through the Department of Housing and Community Affairs (DHCA). The application is submitted online via the county's eRentPay system, which also handles license renewals and tenant registration ^[2]. The application requires basic information: property address, owner name and contact information, the number of rental units, and details about any property manager if you use one. You'll also need to provide a valid email address because the county communicates inspection schedules, renewal reminders, and violation notices electronically ^[2]. Once you submit the application, the DHCA schedules an initial inspection. You cannot legally rent the property until the license is issued, and the license isn't issued until the property passes inspection. First-time applicants should plan for at least 30 to 60 days between application and license issuance, though the timeline can stretch longer if the property fails the initial inspection and requires re-inspection ^[2]. You pay the license fee at the time of application. Fees vary by the number of units and property type; confirm the current fee schedule with the Montgomery County DHCA rental licensing office because the county adjusts these amounts periodically. The fee is not refundable if your property fails inspection ^[1]. If you're new to landlording and want structured preparation for the inspection and licensing process, RentalPermitPath's $79 City Rental License & Inspection Prep Packet organizes the Montgomery County requirements, inspection checklist, and application steps in one place.

What does the rental housing inspection cover?

Montgomery County's rental housing inspection is thorough and examines every part of your property. Inspectors evaluate every rental unit and all common areas for compliance with the county's housing code, which incorporates local health, safety, and building standards ^[3]. Inspectors check structural elements: foundation integrity, roof condition, walls, ceilings, floors. They look at all electrical systems, including outlets, breakers, and whether the wiring is up to code. Plumbing systems get scrutinized too: functional sinks, toilets, showers, water heaters, and no leaks. Heating and ventilation must work correctly. Every unit needs adequate heating capacity for Maryland winters ^[3]. Smoke detectors and carbon monoxide alarms are non-negotiable. Montgomery County requires smoke alarms in every bedroom, outside each sleeping area, and on every level of the dwelling. Carbon monoxide detectors are required on any level with a fuel-burning appliance or an attached garage. Inspectors test these devices during the inspection ^[3]. Exterior inspection points include safe, code-compliant stairs and railings, proper drainage, secure windows and doors, and no exterior hazards like exposed wiring or rotted wood. Common violations that fail properties on the first inspection: missing or non-functional smoke alarms, plumbing leaks, broken windows, inadequate heating, and electrical code violations like overloaded circuits or missing outlet covers ^[3]. Inspectors also verify that the property meets minimum space and occupancy standards. Bedrooms must have a minimum square footage, a window for egress, and a closet. Kitchens must have a working stove, refrigerator, and sink. Bathrooms need a toilet, sink, and bathtub or shower, all in working condition ^[3]. Knowing renters rights before your inspection helps you understand what tenants can legally expect from your property, which aligns directly with what inspectors check.

How long does a rental license last and how do you renew it?

A Montgomery County rental housing license is valid for three years from the date of issuance ^[1]. The county sends renewal notices by email approximately 90 days before expiration. You renew through the same eRentPay portal you used for the initial application ^[2]. Renewal is not automatic. You must submit a renewal application and pay the renewal fee. The county also inspects the property again as part of the renewal process, though the timing of that inspection depends on the property's compliance history and age ^[2]. Properties with a clean inspection record and no code violations may qualify for a longer interval between physical inspections, but you still renew the license every three years. Properties with recent violations or failed inspections face more frequent inspections, sometimes annually ^[1]. If you miss the renewal deadline, the license lapses. Operating a rental property without a valid license exposes you to fines and potential legal action by the county. The county can also issue a cease-and-desist order, which legally prohibits you from renting the property until you bring the license current ^[1]. Set a calendar reminder for 120 days before your license expires. That gives you time to address any maintenance issues before the renewal inspection.

What happens if your property fails inspection?

If your property fails the initial or renewal inspection, the inspector issues a violation notice listing every deficiency. The notice categorizes violations by severity: some are immediate hazards that must be corrected within days, others are standard code issues that give you 30 to 60 days to fix ^[3]. You're responsible for correcting every violation and notifying the DHCA when the work is complete. The county schedules a re-inspection to verify compliance. You pay a re-inspection fee each time the inspector returns. That fee is in addition to the original license fee, and it applies every time the property fails and requires another visit ^[3]. Serious violations like no heat in winter, no working smoke alarms, or structural hazards can result in the county ordering tenants to vacate until repairs are complete. The county can also pursue fines and legal action against landlords who fail to correct violations within the specified timeframe ^[3]. Most first-time failures involve fixable issues: a missing smoke alarm, a leaky faucet, a broken window latch, peeling paint in pre-1978 housing. Budget time and money for these repairs before you apply for the license. Inspect your own property with the county's checklist before the official inspection. Fixing minor issues up front costs less than paying for multiple re-inspections. If you want a complete inspection preparation checklist organized specifically for Montgomery County, RentalPermitPath's City Rental License & Inspection Prep Packet includes every inspection point the DHCA evaluates, with room-by-room guidance.

Do you need to register tenants with the county?

Yes. Montgomery County requires landlords to register each tenant within 30 days of move-in ^[4]. The registration is separate from the rental license but uses the same eRentPay system. You submit the tenant's name, the lease start date, and the monthly rent amount. You also update the system within 30 days when a tenant moves out. The county uses this data to track occupancy, ensure properties aren't over-occupied, and contact tenants directly if there are code violations or emergencies ^[4]. Failure to register tenants is a separate violation from operating without a license, and it carries its own fine. The county audits tenant registration periodically, cross-referencing utility records and other data to identify landlords who skip this step ^[4]. Tenant registration also ties into rent stabilization policies in Montgomery County. The county's rent stabilization law applies to certain older multifamily buildings, and the tenant registration system is how the county monitors compliance with allowable rent increases ^[4].

How to become a landlord in Montgomery County

Becoming a landlord in Montgomery County means acquiring a rental property, obtaining the required rental housing license, and managing the property in compliance with state and local landlord-tenant law. Start by purchasing or inheriting a property you intend to rent. Before you advertise for tenants, apply for the rental housing license through the DHCA's eRentPay system. Do not accept a tenant, sign a lease, or collect rent until the license is issued ^{[1] [2]}. Maryland landlord-tenant law governs most of the relationship: security deposit limits (two months' rent maximum for most leases), required lease disclosures, eviction procedures, and tenant rights ^[5]. Montgomery County adds layers on top of state law: the licensing requirement, mandatory tenant registration, specific local code standards, and rent stabilization rules for certain buildings ^{[1] [4]}. You'll also need landlord insurance. It's not legally required, but no experienced landlord operates without it. A standard homeowner's policy doesn't cover rental activity. Landlord insurance adds liability coverage for tenant injuries and property damage coverage for tenant-caused loss. Many landlords also require tenants to carry renters insurance as a lease condition, which shifts some liability and protects the tenant's belongings ^[6]. Understand Maryland's notice requirements. If you plan to end a month-to-month tenancy, you must give the tenant one full rental period's notice (for month-to-month, that's one month). If you plan to raise rent, the same notice applies. If you're evicting for non-payment or lease violation, the notice period is shorter but follows strict statutory rules ^[5]. Landlording is managing a small business. You handle maintenance calls, collect rent, screen tenants, enforce lease terms, and comply with a thicket of regulations. Many landlords with one or two properties manage them personally; others hire a property manager. A typical property manager in Montgomery County charges 8% to 10% of monthly rent for full-service management ^[6]. If you're new to the business, understanding what a landlord is and does clarifies the full scope of your legal and practical responsibilities.

What is landlording and what is a landlord?

A landlord is a person or entity that owns real property and rents it to another party (the tenant) in exchange for payment. Landlording is the practice of owning and managing rental property, which includes maintaining the property, enforcing the lease, collecting rent, and complying with housing laws. You become a landlord the moment you rent out property you own. It doesn't matter if it's a single basement apartment or a 50-unit building. The law treats you as a landlord with all the accompanying responsibilities ^[5]. Landlording involves recurring tasks: screening applicants, preparing leases, conducting move-in and move-out inspections, responding to repair requests, handling late or missing rent, renewing leases, and occasionally pursuing eviction. It also involves one-time or periodic tasks like property inspections, licensing renewals, tax reporting, and capital improvements. In Montgomery County, landlording also means staying current with the DHCA's rental licensing requirements, registering tenants within 30 days of move-in, and maintaining the property to pass triennial inspections ^{[1] [2] [4]}.

What rights do tenants have without a lease in Maryland?

Tenants in Maryland have strong rights even without a written lease. If a tenant occupies a property and pays rent, a legal tenancy exists. The law presumes a month-to-month tenancy if no written lease specifies a different term ^[5]. A tenant without a written lease still has the right to a habitable property. That means working heat, hot water, plumbing, electricity, and no code violations that pose health or safety hazards. The tenant can withhold rent or pursue rent escrow through the courts if the landlord fails to maintain habitability ^[5]. The tenant also has the right to proper notice before eviction. Even without a lease, a landlord cannot simply lock out a tenant or shut off utilities to force them out. The landlord must follow Maryland's formal eviction process, which starts with written notice (typically 30 days for month-to-month tenancies, shorter for non-payment) and proceeds through district court if the tenant doesn't leave voluntarily ^[5]. Security deposit rules apply equally to tenants without written leases. The landlord can charge a deposit but must follow Maryland's limits (two months' rent for most leases) and return the deposit within 45 days after the tenant moves out, with an itemized list of any deductions ^[5]. A month-to-month tenant can also terminate the tenancy with one full rental period's notice (one month for most month-to-month arrangements). That flexibility cuts both ways: the landlord can also end the tenancy with the same notice, as long as the termination isn't retaliatory or discriminatory ^[5].

Why do landlords require renters insurance?

Landlords require renters insurance because the landlord's property insurance doesn't cover the tenant's belongings or liability for tenant-caused damage. Renters insurance fills that gap. A typical renters insurance policy costs $15 to $30 per month and covers the tenant's personal property (furniture, electronics, clothing) if it's damaged by fire, theft, or certain other perils. It also provides liability coverage if the tenant accidentally injures someone or damages someone else's property, including the landlord's property ^[6]. For landlords, requiring renters insurance reduces disputes. If a tenant's negligence causes a fire or flood that damages the building, the tenant's renters insurance can cover the tenant's liability instead of the landlord suing the tenant personally (a process that's often slow and unproductive if the tenant has no assets). The landlord's property insurance still covers the building structure, but the tenant's policy covers the tenant's liability and belongings ^[6]. Requiring renters insurance also indirectly screens for responsible tenants. Tenants who balk at a $20/month insurance requirement often struggle with other financial responsibilities. Most lease agreements now include a renters insurance requirement as a standard clause, and many landlords verify coverage annually by requesting a certificate of insurance from the tenant's insurer ^[6].

How much notice does a landlord have to give in Maryland?

In Maryland, the amount of notice a landlord must give depends on the type of tenancy and the reason for the notice. For ending a month-to-month tenancy without cause, the landlord must give one full rental period's notice. If rent is due on the first of each month, the landlord must deliver notice by the last day of one month to terminate the tenancy at the end of the following month. That's effectively one month's notice ^[5]. For week-to-week tenancies, the notice period is one week. For annual leases, no notice is required to end the tenancy at the lease's expiration unless the lease specifies otherwise (and many do). The lease simply expires on its end date, though many landlords send courtesy reminders 60 to 90 days out ^[5]. For eviction due to non-payment of rent, the landlord must first give the tenant a 10-day notice to pay or vacate. If the tenant doesn't pay within 10 days, the landlord can file for eviction in district court ^[5]. For eviction based on lease violations (other than non-payment), the landlord must give a 30-day notice to correct or vacate for month-to-month tenancies. If the tenant doesn't fix the violation or move out, the landlord can file for eviction. For leases with a fixed term, the landlord must give a 14-day notice for certain serious violations ^[5]. Montgomery County doesn't alter Maryland's notice requirements in most cases, but the county's rent stabilization ordinance (which applies to certain older multifamily buildings) imposes additional notice requirements for rent increases and certain lease non-renewals ^[4].

What can a landlord look at during an inspection in Maryland?

During a rental property inspection, a landlord can look at any part of the property that affects habitability, safety, or lease compliance. That includes the interior of the rental unit, appliances, plumbing, electrical systems, heating and cooling equipment, smoke and CO alarms, windows, doors, walls, floors, and ceilings. Maryland law requires landlords to provide reasonable notice (usually 24 hours) before entering a tenant-occupied unit, except in emergencies ^[5]. The inspection must occur at a reasonable time, typically during business hours, unless the tenant consents to another time. Landlords commonly conduct move-in inspections, move-out inspections, periodic safety inspections (annually or semi-annually), and inspections triggered by tenant repair requests or suspected lease violations. The landlord can photograph or video-record conditions for documentation, as long as the recording doesn't intrude on the tenant's privacy (for example, the landlord shouldn't record the tenant's personal documents or open closed drawers) ^[5]. The landlord can inspect to verify the tenant isn't damaging the property, isn't violating lease terms (like keeping unauthorized pets or smoking in a no-smoking unit), and that safety equipment like smoke alarms is functioning. The landlord can also inspect to identify needed maintenance or repairs ^[5]. What a landlord cannot do: enter without notice (except emergencies), conduct inspections at unreasonable times or with unreasonable frequency (harassing the tenant), or use inspections as a pretext for retaliation after the tenant complains about code violations or withholds rent through lawful escrow ^[5]. For the Montgomery County rental license inspection, the DHCA inspector (not the landlord) conducts the inspection, and the tenant must allow access. The inspector evaluates code compliance and habitability, not lease compliance. That's a separate function ^[3].

What a landlord cannot do in Ohio

This question addresses Ohio, not Maryland, but the underlying principles translate across states with variations. Landlords in Ohio (and landlords everywhere) cannot engage in certain prohibited conduct, typically defined by state landlord-tenant law and federal fair housing law. Ohio law specifically prohibits landlords from retaliating against tenants who exercise legal rights, such as complaining to a housing inspector, joining a tenant union, or withholding rent through lawful procedures for habitability issues . Retaliation includes raising rent, decreasing services, threatening eviction, or actually evicting a tenant in response to protected activity. Landlords in Ohio cannot shut off utilities, change locks, or remove tenant belongings to force a tenant out. That's an illegal "self-help" eviction. The landlord must use the formal court eviction process . Landlords cannot discriminate based on race, color, religion, sex, national origin, familial status, or disability (federal Fair Housing Act protections). Ohio adds age as a protected class in some contexts. Discrimination can occur in advertising, tenant screening, lease terms, or access to property amenities . Landlords cannot enter a rental unit without proper notice except in emergencies. Ohio doesn't specify a statutory notice period, so "reasonable notice" (commonly interpreted as 24 hours) applies. Repeated unannounced entries can constitute harassment . Landlords cannot keep a security deposit without proper itemization and documentation. Ohio requires landlords to return the deposit or provide an itemized list of deductions within 30 days after the tenant moves out . For Montgomery County, Maryland landlords, the equivalent prohibitions exist under Maryland Code and federal law. Maryland prohibits retaliatory eviction, self-help eviction, discrimination, and illegal withholding of security deposits ^[5] . The Maryland rules for notice before entry and security deposit return timelines differ slightly from Ohio's (45 days for deposit return in Maryland, 30 in Ohio) ^[5] , but the core prohibitions are the same. When you prepare for your Montgomery County rental license, make sure you understand both Maryland landlord-tenant law and the county's specific licensing and code requirements.

Frequently asked questions

How much does a Montgomery County rental license cost?

License fees vary by property type and the number of rental units. Single-family homes, duplexes, and small multifamily properties pay different rates. Confirm current fee amounts with the Montgomery County Department of Housing and Community Affairs rental licensing office, as the county adjusts fees periodically. Re-inspection fees apply if your property fails the initial inspection.

Can I rent out my property in Montgomery County without a license?

No. Operating a rental property without a valid Montgomery County rental housing license is illegal and exposes you to fines and potential cease-and-desist orders. The county can legally prohibit you from renting the property until you obtain the license. You must have the license before you accept tenants or collect rent.

How long does it take to get a Montgomery County rental license?

Plan for 30 to 60 days from application submission to license issuance for first-time applicants. The timeline depends on inspection scheduling and whether your property passes on the first inspection. Properties that fail and require re-inspection take longer. Apply well before you plan to accept tenants.

Does Montgomery County inspect every rental unit?

Yes. The Department of Housing and Community Affairs inspects every rental unit as part of the initial licensing process and again at renewal. The inspection covers the interior of each unit, common areas, and exterior elements. The inspection frequency depends on the property's age, compliance history, and any reported violations.

What happens if I don't register my tenants in Montgomery County?

Failing to register tenants within 30 days of move-in is a separate violation from operating without a license, and it carries its own fine. The county audits tenant registration and can cross-reference utility records to identify unregistered tenants. Register every tenant through the eRentPay system promptly after move-in.

Can a tenant withhold rent in Maryland if the landlord doesn't make repairs?

Yes. Maryland law allows tenants to withhold rent and pay it into a court-administered escrow account if the landlord fails to make necessary repairs that affect habitability. The tenant must follow specific procedures, including notifying the landlord and filing with the district court. The court inspects the property and decides whether to release the escrowed rent to the landlord or order repairs first.

How much can a landlord raise rent in Montgomery County?

For most rental properties, Maryland law does not cap rent increases, and the landlord can raise rent by any amount with proper notice (one rental period's notice for month-to-month tenancies). However, Montgomery County's rent stabilization law limits rent increases for certain older multifamily buildings. Check whether your property is subject to rent stabilization through the DHCA.

Can a landlord evict a tenant without a court order in Maryland?

No. Maryland law requires landlords to use the formal eviction process, which involves giving proper notice and filing an eviction action in district court. Self-help evictions (changing locks, shutting off utilities, removing tenant belongings) are illegal. Even if a tenant is behind on rent or violating the lease, the landlord must obtain a court order to evict.

Do I need a rental license for a single-family home in Montgomery County?

Yes. Montgomery County's rental housing license requirement applies to single-family homes, condos, townhouses, and all other residential rental properties. Owner-occupied properties where you rent out a room or basement unit also require licensing. Very few exemptions exist, and most single-family landlords must license their properties.

How do I find out if my Montgomery County rental license is about to expire?

The county sends renewal reminders by email approximately 90 days before your license expires. Log in to the eRentPay system to view your current license status and expiration date. Set your own calendar reminder for 120 days before expiration to allow time for any needed repairs before the renewal inspection.

Can a Montgomery County inspector enter my rental property without the tenant's permission?

The tenant must allow the county inspector access for the required rental housing inspection. The DHCA schedules inspections and notifies both the landlord and the tenant. If a tenant refuses entry, the landlord can be held responsible for failing to complete the inspection, which can delay or prevent license issuance or renewal. Work with your tenant to ensure access.

What is the penalty for operating an unlicensed rental property in Montgomery County?

The county can issue fines for operating without a license and can also issue a cease-and-desist order prohibiting you from renting the property until you obtain the license. Repeated or willful violations can result in escalating fines and potential legal action. The county treats unlicensed rental operation as a serious code violation.

Can I transfer a Montgomery County rental license to a new owner?

No. Rental housing licenses are not transferable. When you sell a rental property, the new owner must apply for a new license in their name. The property will undergo a new inspection as part of the new owner's licensing process. Advise buyers of this requirement during the sale process to avoid delays.

Does Montgomery County require landlords to provide smoke alarms and carbon monoxide detectors?

Yes. Montgomery County requires smoke alarms in every bedroom, outside each sleeping area, and on every level of the dwelling. Carbon monoxide detectors are required on any level with a fuel-burning appliance or an attached garage. Inspectors test these devices during rental housing inspections, and missing or non-functional alarms are common reasons for failed inspections.
