Rental license in Montgomery County MD: full 2026 guide

Last updated 2026-07-25

Do you need a rental license in Montgomery County, MD?

Yes. Montgomery County Code Chapter 29 (Landlord-Tenant Relations) requires an owner to have a valid rental license before renting out a dwelling unit anywhere in the county, with narrow exceptions for owner-occupied situations and a few other carve-outs spelled out in the law ^[1]. This applies whether you own a single rented basement apartment or a ten-unit building. The county's own guidance says plainly that "a person must not operate a rental facility unless the person holds a rental license issued by the Department" ^[1]. The license requirement is county-wide, but it sits on top of anything your specific municipality inside the county requires. Rockville, Gaithersburg, and Takoma Park, for example, run their own separate rental licensing programs layered on top of the county's, so if your property sits inside one of those city limits you may owe two licenses, not one. Always confirm with your city rental licensing office whether a municipal license applies in addition to the county one. The license attaches to the rental facility (basically, the unit or building), not to you personally, and it needs renewal on a schedule set by DHCA. If you buy a property that already has tenants in it, you still need to get the license transferred or reissued in your name; it doesn't automatically carry over with the deed.

How do you apply for a Montgomery County rental license?

You apply through the Department of Housing and Community Affairs (DHCA), which administers licensing and inspections for rental housing in the county ^[2]. The application asks for basic ownership information, the property address, unit count, and whether you use a managing agent. DHCA has moved much of this online through its licensing portal, so check the current DHCA rental licensing page for the active application system before you start, since portals and forms get updated periodically. A few things to gather before you sit down to apply: your deed or proof of ownership, the names and contact information for anyone managing the property on your behalf, and a working email address, since DHCA correspondence (renewal notices, inspection scheduling, violation notices) increasingly comes electronically. Once DHCA processes the application and you've paid the fee, you'll get a license number and, for most properties, a scheduled or on-request inspection. New applicants should expect the license to not be considered final or fully active until that inspection is done, so don't rent the unit out and just assume you're covered because you submitted paperwork and a check. If you're managing this process for the first time, it helps to have a checklist that maps out every document you'll need for licensing and inspection prep before the notice deadline arrives. The tenant rights side of the relationship also matters here, since the license and the lease terms interact, and Montgomery County's landlord-tenant code sets baseline protections regardless of what your lease says.

What does a rental license cost in Montgomery County?

Montgomery County's rental license fee is set in the fee schedule attached to Chapter 29 and DHCA's licensing regulations, and the amount depends on the number of units and whether it's a first-time application or a renewal. Fee amounts get updated periodically by the County Council, so confirm the current fee with your city rental licensing office or directly on the DHCA fee schedule before you budget for it, rather than relying on a number you saw a year or two ago. On top of the license fee itself, expect a possible inspection fee if a reinspection is needed after a failed initial inspection, and possible late fees if you apply after you've already started renting the unit. DHCA's compliance approach treats renting without a license as a violation subject to civil penalties, separate from whatever the license fee itself costs ^[1]. Budget for these as three separate line items: the license application/renewal fee, any reinspection fee, and, worst case, a civil penalty if you got caught renting unlicensed. That last one is avoidable. The first two aren't.

What is a Code Red inspection and when does it happen?

Montgomery County calls its rental housing inspection program "Code Red," and it's the mechanism DHCA uses to confirm a rental unit meets the county's housing code before and during licensing ^[2]. A licensing inspector checks things like working smoke alarms, carbon monoxide alarms where required, safe electrical and plumbing systems, adequate heat, and the general habitability of the unit. New rental licenses generally require an initial inspection before or shortly after the license issues. After that, DHCA inspects on a renewal cycle, and the frequency can depend on the property's compliance history. A unit with a clean record may go multiple years between full inspections, while a property with prior violations can get inspected more often. Confirm your property's specific inspection cycle with DHCA, since the schedule isn't identical for every unit type. If your unit fails, you'll get a list of violations and a deadline to fix them, then a reinspection. Common fail points nationally, and reported anecdotally by property managers in similar jurisdictions, include missing or expired smoke detectors, blocked emergency egress windows, and exposed wiring, so those are worth checking yourself before an inspector ever shows up.

What can a landlord look at during an inspection?

A licensing or code-compliance inspector in Montgomery County can walk through the interior and exterior of the rental unit to check for housing code compliance: functioning smoke and carbon monoxide alarms, safe electrical outlets and panels, working plumbing with no active leaks, adequate heating, secure locks on doors and windows, and freedom from infestation or structural hazards. This is a habitability and safety check, not a general search of your belongings. Inspectors typically look inside every habitable room, including bedrooms, kitchens, and bathrooms, and they'll check mechanical systems (furnace, water heater) and common areas in multi-unit buildings. They are not there to inventory personal property or go through drawers and closets. If a tenant is present, county practice is generally to inspect with reasonable notice to the occupant, similar to the notice rules that apply to landlord-initiated entries under the county's landlord-tenant law. This question comes up outside Maryland too, and the mechanics are similar in most licensing jurisdictions: who is responsible for a rental property walkthrough inspection in places like California is usually the local code enforcement or building department, not a private party, and the inspector's scope is limited to code compliance items, not general snooping. California's Health and Safety Code, for instance, authorizes local enforcement agencies to inspect for building and housing code violations under the State Housing Law framework , which functions similarly to Montgomery County's Code Red model even though the statutes differ.

How much notice does a landlord have to give before entering a rental unit or scheduling an inspection?

Maryland law and Montgomery County practice both lean toward reasonable advance notice before a landlord or the county enters an occupied unit, though the exact number isn't uniformly fixed by one statewide statute the way it is in some other states. Montgomery County's landlord-tenant regulations under Chapter 29 address landlord entry and notice obligations as part of the broader tenant protections in the chapter ^[1]. As a practical matter, most Montgomery County leases and DHCA guidance point landlords toward giving at least 24 to 48 hours' notice for non-emergency entry, including licensing inspections, unless the tenant agrees to shorter notice or there's an emergency. If you're scheduling a Code Red inspection in an occupied unit, coordinate the date directly with your tenant well before the appointment, because a missed inspection due to no access can delay your license renewal and, in some cases, trigger a rescheduling fee. Don't treat this as a suggestion. Showing up unannounced, even for a legitimate government inspection, damages trust and can create a dispute you didn't need. Put the notice in writing (text or email works) so you have a record.

What happens if you rent without a license in Montgomery County?

Renting a unit without the required Montgomery County rental license is a code violation, and DHCA can issue civil citations and fines against the owner ^[1]. Beyond the fine itself, operating unlicensed creates a bigger practical problem: Maryland courts have generally held that a landlord who doesn't hold a required rental license can be barred from using the court system to collect rent or pursue eviction until the license issue is resolved, since the licensing requirement functions as a condition tied to the legality of the tenancy in licensing jurisdictions. That second consequence is the one that actually hurts landlords financially. A fine is a fine, you pay it and move on. Losing your ability to file a failure-to-pay-rent case or eviction action because you never got licensed can mean months of unpaid rent with no fast legal remedy. If you're behind on renewing an existing license, or you never applied at all, treat catching that up as urgent, not a someday task. If you've already gotten a violation notice, don't ignore the deadline on it. Contact DHCA, get clear on what's owed and what inspection or paperwork is outstanding, and close it out. Letting it sit usually makes the fine bigger and the path back to a valid license longer.

What rights do tenants have without a lease in Montgomery County?

A tenant without a written lease in Montgomery County still has real legal protections. Maryland law treats an unwritten, ongoing tenancy (commonly called a periodic or month-to-month tenancy) as still governed by state landlord-tenant statutes and by Montgomery County's Chapter 29, which applies regardless of whether the arrangement is in writing ^[1]. That means notice-to-vacate rules, habitability requirements, and security deposit rules under Maryland's security deposit statute still apply ^[3]. A tenant without a lease is entitled to a habitable unit, proper notice before eviction (Maryland generally requires formal court process for eviction regardless of lease status), and the same basic protections against retaliation and discrimination that written-lease tenants get. What a no-lease tenant typically doesn't have is the specific negotiated terms (rent amount changes, specific maintenance responsibilities) that a written lease would otherwise spell out, which is exactly why relying on verbal agreements is a bad idea for both sides. If you're a landlord operating without written leases right now, get that fixed. It's more than a tenant-protection issue, it's also weaker footing for you if a dispute ends up in front of a judge. For background on what tenants can and can't do or expect, see tenants rights and renters rights.

Why do landlords require renters insurance?

Many Montgomery County landlords require renters insurance as a lease condition because it shifts liability for a tenant's personal property loss and certain injury claims away from the landlord's own policy. If a tenant's belongings are damaged in a fire or water event, or if a guest gets hurt inside the tenant's unit due to something the tenant is responsible for, renters insurance is what pays that claim instead of it becoming a dispute with the landlord. Maryland doesn't require renters insurance by state law, and Montgomery County's rental licensing rules don't mandate it either. It's a landlord choice, written into the lease, not a Chapter 29 requirement. That said, it's become close to standard practice among small landlords in the D.C. area because a typical policy costs relatively little (often in the range of $15 to $30 a month depending on coverage and the tenant's location) compared to the exposure a landlord faces without it. Requiring it also creates a paper trail: if a tenant's actions damage the unit beyond normal wear and tear, having proof of an active renters policy can speed up how a claim gets resolved, whether through the tenant's insurer or through the security deposit process under Maryland's deposit law ^[3].

What is a landlord and what is landlording, exactly?

A landlord is the person or entity that owns residential (or commercial) property and rents it to another party, the tenant, in exchange for periodic payment, usually monthly rent. Legally, in Maryland, a landlord takes on obligations under the state's landlord-tenant statutes (Real Property Article, Title 8) ^[4] and, in Montgomery County specifically, under Chapter 29 of the County Code ^[1], including habitability duties, security deposit handling rules, and licensing requirements if the property is a rental facility. "Landlording" is the informal but widely used term for the actual work of running rental property day to day: screening tenants, collecting rent, handling maintenance requests, keeping up with licensing and inspection deadlines, managing lease renewals, and staying current on the legal rules that apply in your jurisdiction. It's part legal compliance, part small business operations, part customer service. Landlords who treat it purely as passive income tend to get surprised by licensing notices, inspection fails, and code violations, because none of that runs on its own. For a broader look at what the role actually involves across different cities, see landlord and landlord landlords.

How do you become a landlord in Montgomery County, step by step?

Becoming a landlord in Montgomery County means more than buying a property and putting up a listing. Here's the realistic order of operations. 1. Confirm zoning allows the rental use for your property type (single-family, accessory dwelling unit, multifamily), since some residential zones have restrictions on rentals or require separate approvals for accessory apartments. 2. Apply for a Montgomery County rental license through DHCA before you advertise the unit for rent ^[1][2]. 3. Schedule and pass the required Code Red inspection. 4. Check whether your specific municipality (Rockville, Gaithersburg, Takoma Park, etc.) requires an additional local license, and confirm current fees and deadlines with that city rental licensing office. 5. Draft a written lease that complies with Maryland's Real Property Article Title 8 and Montgomery County Chapter 29, including proper security deposit handling under the state's deposit statute (deposits are capped, and interest rules and return timelines apply) ^[3][4]. 6. Screen tenants consistently and in compliance with the federal Fair Housing Act and Maryland's own anti-discrimination protections ^[5]. 7. Set up rent collection, maintenance response, and a system for tracking your license renewal and inspection dates so you're not caught off guard two or three years down the road. Step 5 and step 2 trip up more first-time landlords than anything else. People get the lease right and forget the license, or they get the license and rent out an old lease template that hasn't been updated in a decade.

How do you be a landlord well, more than legally?

Being a landlord "well" is really about two things: staying ahead of your compliance obligations, and treating the tenant relationship like it's worth maintaining. The compliance side is concrete: track your license renewal date, your inspection cycle, your lease renewal dates, and any local ordinance changes (Montgomery County updates Chapter 29 periodically, and so do individual cities within the county). A simple calendar reminder system beats memory every time. Landlords who lose their license or get hit with a violation notice almost always say the same thing afterward: they knew the deadline existed, they just didn't track it anywhere. If you want a structured way to get organized before a licensing notice or inspection deadline hits, the $79 City Rental License & Inspection Prep Packet walks through exactly what documentation Montgomery County landlords typically need gathered, though it's not a substitute for checking DHCA's current requirements directly. On the relationship side, respond to maintenance requests promptly (Maryland's implied warranty of habitability means you're on the hook for things like heat, working plumbing, and safe electrical systems regardless of what the lease says), give real notice before entry, and don't let small disputes turn into standoffs. A tenant who trusts you tends to report problems early, before they become expensive repairs or code violations you get cited for.

What can a landlord not do (Ohio comparison and general rules)

This question gets searched a lot because landlord-tenant rules vary sharply by state, and someone managing property in Montgomery County, Maryland may also own property in Ohio or elsewhere. In Ohio, landlord obligations and restrictions are set out in Ohio Revised Code Chapter 5321, the Ohio Landlords and Tenants Act ^[6]. Under that chapter, an Ohio landlord generally cannot enter a rental unit without reasonable notice (Ohio courts and the statute point to notice, generally interpreted around 24 hours in practice, though the statute itself says "reasonable" notice rather than a fixed number) ^[6], cannot shut off utilities or change locks to force a tenant out (no self-help eviction), cannot retaliate against a tenant for reporting code violations or joining a tenant union, and cannot discriminate based on protected classes under fair housing law ^[5]. Montgomery County and Maryland follow similar broad strokes even though the specific statute numbers differ: no self-help eviction (a landlord must go through the District Court process to remove a tenant), no shutting off utilities to force a move-out, no retaliation against a tenant who reports a housing code violation to DHCA, and no discrimination based on race, religion, disability, source of income, or the other protected categories under the Fair Housing Act and Maryland's own civil rights law ^[5]. The theme across every state's landlord-tenant law, whether it's Ohio's Chapter 5321 or Maryland's Real Property Article Title 8, is the same: landlords can't take the law into their own hands. Eviction, entry, and deposit handling all have to go through the process the statute sets out, not whatever feels fastest.

Frequently asked questions

Does every rental unit in Montgomery County, MD need a license?

Almost every rental unit does. Montgomery County Code Chapter 29 requires a rental license for units offered for rent, with limited exceptions the county spells out (certain owner-occupied situations, for example). Confirm your specific property's status with DHCA, since exemptions are narrow and easy to misread.

How long does a Montgomery County rental license last before renewal?

Renewal cycles vary based on property type and compliance history, and DHCA sets the specific schedule. Rather than assume a fixed number of years, confirm your unit's renewal date and inspection cycle directly with DHCA's rental licensing division, since it isn't identical for every property.

What is Code Red in Montgomery County housing inspections?

Code Red is Montgomery County's name for its rental housing inspection program, run by DHCA, that checks licensed rental units for housing code compliance covering things like smoke alarms, safe electrical systems, working plumbing, and adequate heat before and during licensing.

Can I be fined for renting without a license in Montgomery County?

Yes. DHCA can issue civil citations for operating a rental facility without a required license under Chapter 29. Beyond the fine, an unlicensed landlord can also face limits on using the courts to collect rent or pursue eviction until the license issue is fixed.

Do Rockville, Gaithersburg, or Takoma Park have separate rental licenses from the county?

Yes, several municipalities inside Montgomery County run their own rental licensing programs on top of the county's DHCA license. If your property sits inside one of these city limits, confirm with that specific city rental licensing office whether an additional local license and inspection are required.

Who is responsible for a rental property walkthrough inspection in California?

In California, local code enforcement or building/housing departments generally conduct compliance inspections under the state's Health and Safety Code framework for the State Housing Law, similar in function to Montgomery County's DHCA-run Code Red program, though the specific statutes and local rules differ by city and county.

What can a landlord look at during a licensing inspection?

An inspector checks housing-code items: smoke and carbon monoxide alarms, electrical and plumbing safety, heating, structural and egress safety, and general habitability. It's a code-compliance check of the unit and mechanical systems, not a search of personal belongings or private areas beyond what's needed to verify code items.

How much notice does a landlord have to give before entering a unit in Montgomery County?

Montgomery County and Maryland practice generally favor reasonable advance notice, commonly 24 to 48 hours, for non-emergency entry including inspections, unless the tenant agrees otherwise or there's a genuine emergency. Put notice in writing and coordinate inspection timing directly with the tenant.

What rights does a tenant have without a written lease in Maryland?

A tenant without a written lease in Montgomery County still gets protection under Maryland's Real Property Article Title 8 and County Chapter 29: a habitable unit, formal court process before eviction, security deposit protections, and protection from retaliation and discrimination, even though specific negotiated lease terms don't exist without a written agreement.

Why do landlords require renters insurance if it's not legally mandated?

Maryland and Montgomery County don't require renters insurance by law, but many landlords require it in the lease because it shifts liability for a tenant's personal property loss and certain injury claims onto the tenant's insurer rather than the landlord, at a typical cost of roughly $15 to $30 a month for the tenant.

What can a landlord not do under Ohio law?

Under Ohio Revised Code Chapter 5321, a landlord cannot enter without reasonable notice, cannot shut off utilities or change locks to force a tenant out, cannot retaliate against a tenant for reporting code violations, and cannot discriminate based on protected classes under fair housing law.

What's the first thing to do if I get a rental licensing violation notice in Montgomery County?

Read the notice for the exact violation and deadline, then contact DHCA directly to confirm what's required to resolve it, whether that's paying a fee, scheduling a reinspection, or submitting missing paperwork. Don't let the deadline pass without contact; that's when fines and legal exposure escalate.

Does buying a property with existing tenants transfer the rental license to the new owner?

No. A Montgomery County rental license does not automatically transfer with the deed. A new owner needs to apply for the license in their own name (or transfer it through DHCA's process) even if tenants are already in place and the prior owner held a valid license.
