DC rent registry: what landlords must file, step by step

Last updated 2026-07-25

What is the DC rental accommodations registration and who has to file it?

The District of Columbia requires every owner of rental housing to register their units with the Rental Accommodations Division (RAD), part of the Department of Housing and Community Development (DHCD), under the Rental Housing Act of 1985 (D.C. Law 6-10, codified at D.C. Code § 42-3502.05) ^[1]. This isn't optional paperwork you can get around by staying quiet. If you rent out a unit in DC, whether it's a single condo, an English basement, or a ten-unit building, the law expects you to either register it as a covered rental or file a Claim of Exemption explaining why it isn't covered. Owners submit Form RAD-1 (Registration/Claim of Exemption Form) to register a housing accommodation or to assert that a specific exemption applies, such as owner-occupied buildings with four or fewer units. The practical reason this matters more than a typical city rental registry: DC's registration status determines whether your units fall under rent control. Get this wrong and you could end up making illegal rent increases for years without knowing it, which creates real financial exposure when a tenant or the Office of Administrative Hearings looks back at your file.

How do I know if my DC rental unit is exempt from rent control?

Owner-occupied building, 4 units or fewer	Often exempt from rent control	File Claim of Exemption (Form RAD-1)
Building constructed after 1975	Often exempt from rent control	File Claim of Exemption, confirm construction date documentation
Housing provider owns 4 or fewer units citywide	Often exempt	File Claim of Exemption
Single-family home or condo, larger portfolio owner	Usually not automatically exempt	Register as covered rental, confirm with DHCD
Building built before 1975, 5+ units, non-owner-occupied	Usually covered by rent control	Register, track allowable annual rent increase	Confirm your specific situation with DHCD before you assume you're exempt. Don't guess.

Not every rental unit in DC is subject to rent stabilization, but almost all of them still have to be registered or have an exemption on file. D.C. Code § 42-3502.05(a) spells out exemption categories including buildings with fewer than five units where the owner lives on the property, housing built after 1975, and units owned by housing providers who have four or fewer rental units total in the District ^[1]. Here's the trap: claiming an exemption is not automatic just because your building technically qualifies. You have to file the Claim of Exemption. If you never file anything, DHCD and the Office of Administrative Hearings can treat your units as covered by rent control by default, meaning any rent increase you've charged over the years could be challenged as excessive. A rough guide to common DC exemption categories: | Situation | Likely exemption status | What you still must do |

What does it cost to register a rental unit in DC?

DHCD charges registration and license fees tied to the Basic Business License (BBL) structure, since most DC rental housing providers also need a Certificate of Occupancy and a BBL endorsed for rental housing ^[2]. Fee amounts vary by number of units and license category, and DC periodically adjusts them. Because fee schedules change and licensing categories get restructured from time to time, confirm the current registration and license fee with DHCD or the Department of Licensing and Consumer Protection (DLCP) before you budget for it. Treat any number you see online, including here, as a starting point to verify, not a locked-in figure. What you can count on: fees are billed per rental unit or per building depending on category, and you'll typically pay again at renewal, which in DC is generally handled through the Basic Business License two-year renewal cycle rather than an annual rent registry fee alone ^[2]. Late renewal usually triggers a penalty on top of the base fee.

What happens if I never register my DC rental unit?

Failing to register (or file an exemption) doesn't just mean a missed form. It can unravel your rent history. Under the Rental Housing Act framework, a housing provider who has not properly registered a unit may be barred from implementing rent increases, and a tenant can file a petition challenging back rent as an illegal rent increase ^[1]. DC's Office of Administrative Hearings adjudicates these disputes, and tenants have used unregistered status successfully to roll back rent increases and, in some cases, recover overpayments. This is the sharpest version of "the paperwork problem becomes a money problem" you'll find in any US rental registry system. It's more than a fine for noncompliance. It's a potential clawback of rent you already collected and spent. Separately, operating rental housing without the required Basic Business License endorsement can draw civil fines from DLCP. Because DC's civil fine schedules for licensing violations are adjusted periodically and vary by violation type, confirm current fine amounts with DLCP or DHCD rather than relying on a number that might be outdated by the time you read this. If you're dealing with a violation notice right now, the first move is figuring out whether the underlying registration or exemption was ever filed at all. Sometimes a previous owner registered the building and the paperwork trail is thin. Pulling your building's history from DHCD's records is the fastest way to find out where you actually stand.

How do rent increase limits work once a unit is registered?

If your unit is registered as covered by rent control, DC limits how much you can raise rent each year, tied to the Consumer Price Index (CPI-W) for the Washington-Baltimore area plus a fixed percentage, capped under the Rental Housing Act's formula ^[1]. DHCD publishes the annual allowable increase percentage each year, and it changes based on CPI data from the Bureau of Labor Statistics. For elderly or disabled tenants, DC caps the allowable increase lower than the general formula, and housing providers have to give proper written notice before any increase takes effect. The notice period and required form content are separate from the registration question, but you can't legally raise rent on a covered unit you haven't registered. Full stop. If your unit is exempt (say, a small owner-occupied building under the exemption threshold), these CPI-based caps don't apply, but you still typically have to give required notice before increasing rent, and DC has separate general landlord-tenant notice rules that apply regardless of rent control status.

How much notice does a landlord have to give before a rent increase or entry?

This is a common point of confusion because "notice" means different things depending on what you're doing. For rent increases on rent-controlled units in DC, housing providers generally must give at least 30 days' written notice before the increase takes effect, and the increase can't exceed the annually published CPI-based cap ^[1]. For lease termination or non-renewal, DC's notice periods vary by the reason for termination and can run from 30 days up to 90 days or longer for certain grounds, under the Rental Housing Act's eviction protections. These are separate rules from most other states because DC has some of the strongest just-cause eviction protections in the country. You generally can't simply decline to renew a tenant's lease without a legally recognized reason. For entry to inspect or show a unit, DC law doesn't set one single statewide number the way some states do (some states specify 24 hours, for example), but reasonable advance notice and a legitimate purpose are the general standard tenants and courts expect. If you're unsure what counts as reasonable for your situation, that's worth confirming with DHCD or a DC landlord-tenant attorney rather than assuming a number from another state applies here. This is one of many places where DC's system differs meaningfully from typical landlord-tenant law elsewhere, which matters if you own property in multiple jurisdictions. Compare this to general tenants rights frameworks, since the baseline protections shift by state and by whether rent control applies.

What is landlording and what does a DC landlord actually have to manage?

"Landlording" is the everyday word for the ongoing job of owning and operating rental property: collecting rent, handling repairs, screening tenants, managing lease renewals, and staying compliant with local law. It's distinct from just "owning" property because it's active, recurring work, not a one-time purchase. In a jurisdiction like DC, landlording carries more compliance weight than in most places because of the layered requirements: Basic Business License and Certificate of Occupancy through DLCP, rental unit registration or exemption through DHCD, rent control compliance if applicable, and just-cause eviction rules under the Rental Housing Act ^{[1] [2]}. A landlord who treats DC like a light-touch landlord-tenant state is going to get surprised, usually at the worst possible moment (a tenant dispute or a license renewal). What is a landlord, formally? It's the party who owns or controls a rental unit and leases it to a tenant in exchange for rent, taking on the legal duties that come with that relationship: habitability, proper notice, and (in DC specifically) registration and licensing obligations tied to the unit itself, more than the owner's name.

How do you become a landlord in DC, step by step?

Becoming a landlord in DC isn't just buying a property and putting up a listing. There's a compliance sequence, and skipping steps is what generates fines and rent-control disputes later. Here's the realistic order: 1. Get or confirm the property's Certificate of Occupancy is appropriate for rental use, through DCRA/DLCP. 2. Apply for a Basic Business License endorsed for rental housing through DLCP. 3. Register the rental unit (or file a Claim of Exemption) with DHCD using Form RAD-1 ^[1]. 4. Determine whether the unit is covered by rent control and, if so, understand the CPI-based annual increase cap that applies going forward. 5. Set up a compliant lease and required disclosures (lead paint disclosure if the building predates 1978, security deposit handling rules, etc.). 6. Screen tenants consistent with DC's Human Rights Act and fair housing rules. 7. Collect rent and manage the tenancy going forward, keeping records of registration, license renewal dates, and any rent increase notices. Skipping step 3 is the single most common and most expensive mistake. Owners buy a building, start renting units immediately, and don't realize registration was ever required until a tenant files a petition years later challenging every rent increase since move-in.

What can a landlord look at during a rental inspection?

DC doesn't run a blanket mandatory unit-by-unit inspection program the way some cities do (Baltimore and parts of California have more routine inspection cycles), but Certificate of Occupancy inspections and habitability inspections triggered by tenant complaints do happen through DCRA/DLCP and DOH. During any inspection, whether it's a routine licensing inspection or one triggered by a complaint, inspectors generally check for things like functioning smoke and carbon monoxide detectors, working heat, no active leaks or mold, safe electrical systems, secure locks, and general compliance with DC's Housing Regulations (14 DCMR). When a landlord personally enters a unit to inspect condition (not a government inspection but the owner checking on their property), that's governed by the reasonable notice standard discussed earlier, not a formal government inspection process. The landlord can look at general condition and confirm the tenant isn't violating lease terms (unauthorized occupants, property damage, unauthorized pets), but can't use an inspection visit as pretext to search personal belongings or harass a tenant. For a general comparison of who handles walkthrough inspections in other states, California's system assigns responsibility differently than DC's. In California, routine rental inspections (where a jurisdiction has adopted one) are typically conducted by city or county code enforcement staff, not the landlord personally, under local rental inspection ordinances that vary by city ^[3]. That's a meaningfully different model than DC's complaint-driven and licensing-triggered approach, so don't assume DC's rules and California's rules line up if you own property in both places.

What rights do tenants have without a signed lease in DC?

A tenant without a written lease in DC still has real rights. DC law treats an unwritten, ongoing tenancy (month-to-month by default once a lease term ends or was never signed) as fully covered by the Rental Housing Act's protections, including just-cause eviction requirements and habitability standards under the Housing Regulations ^[1]. Landlords sometimes assume a handshake arrangement means fewer obligations. It doesn't. Without a written lease, a tenant generally still has the right to a habitable unit, protection from termination without a legally recognized cause, required notice before eviction proceedings, and protection from illegal rent increases if the unit is registered and covered by rent control. For landlords, this cuts both ways: no written lease also makes it harder for you to prove what was agreed on if a dispute arises, so it's generally a bad practice regardless of what city you're in. If you're managing a DC unit under an informal arrangement, getting a written lease in place, even a short one, protects both sides better than relying on DC's default tenancy rules alone.

Why do landlords require renters insurance, and does DC mandate it?

Renters insurance covers a tenant's personal belongings and liability, and it protects the landlord indirectly by reducing disputes over who pays when a tenant's stuff is damaged by a fire, burst pipe, or other covered event. The landlord's own property insurance covers the building structure, not the tenant's furniture or electronics, and it typically doesn't cover a tenant's liability if they cause damage to a neighboring unit or injury to a guest. DC does not have a citywide law mandating renters insurance the way some jurisdictions require it as a lease condition, but plenty of individual landlords require it anyway as a lease term, and that's generally enforceable as long as it's a standard, non-discriminatory requirement applied to all tenants. If you require renters insurance, put the minimum coverage amount and proof-of-insurance requirement directly in the lease, and keep a copy of the tenant's policy declarations page on file. This is a landlord-basics practice worth adopting no matter which city you operate in; see landlord basics resources for more on structuring these requirements.

What can a landlord not do in Ohio, for comparison with DC?

Since landlords sometimes own property in multiple states, it's worth flagging how differently Ohio treats landlord-tenant law compared to DC. Ohio's Landlord-Tenant Act (Ohio Revised Code Chapter 5321) prohibits landlords from shutting off utilities to force a tenant out, changing the locks without a court order (self-help eviction), retaliating against a tenant for reporting code violations, or entering the unit without reasonable notice ^[4]. Ohio landlords also cannot fail to maintain the property in a fit and habitable condition, ignore a written notice of a needed repair for an unreasonable period, or retain a security deposit beyond 30 days after move-out without an itemized list of deductions under R.C. 5321.16 ^[5]. The big-picture difference from DC: Ohio doesn't have a statewide rent control or mandatory registration system, and eviction protections are generally lighter than DC's just-cause framework. That's a real structural difference, more than paperwork variation, and it matters if you're deciding where to expand a rental portfolio or trying to apply DC habits to an Ohio property (or vice versa).

Where do I find and file the DC rental registration form?

The form you need is DHCD's RAD-1, Registration/Claim of Exemption, filed with the Rental Accommodations Division. You'll need the property address, unit count, owner information, and, if you're claiming an exemption, documentation supporting the specific exemption category (proof of owner-occupancy, certificate of occupancy date for post-1975 construction, or a sworn statement about total units owned citywide). Before you file anything, it's worth pulling together everything DHCD and DLCP are likely to ask for in one pass rather than making multiple trips: your Certificate of Occupancy, Basic Business License application or renewal, the RAD-1 form, and your lease documentation. Building that packet once and keeping it updated saves real time at renewal, and it's exactly the kind of prep work our $79 City Rental License & Inspection Prep Packet is built around, organizing what a specific city's rental office actually asks for so you're not guessing at the counter. If your building already has a registration history, request your existing RAD file from DHCD before you file anything new. Sometimes a prior owner already registered the property, and re-filing incorrectly can create conflicting records that are a headache to untangle later.

What should I do right now if I got a violation notice or missed a deadline?

First, figure out exactly what the notice is citing: unregistered rental unit, expired Basic Business License, missing Certificate of Occupancy, or a habitability complaint from a tenant. Each of these routes through a different DC agency (DHCD for registration, DLCP for licensing, DCRA/DOH for habitability and occupancy), so the fix looks different depending on which one you're dealing with. Second, don't ignore it or assume it'll resolve itself. DC's Office of Administrative Hearings handles disputes and enforcement actions tied to the Rental Housing Act, and unregistered status can retroactively affect your rent history even if you register today. Filing late is almost always better than not filing. Third, before you pay a fine or file paperwork, call DHCD directly and ask what specifically needs to happen to clear the violation. Fee amounts, exemption categories, and required documentation change over time, and a five-minute phone call beats guessing based on something you read online, including this article. This isn't legal advice, and if the violation involves a tenant dispute or potential rent rollback, that's worth a conversation with a DC landlord-tenant attorney or legal aid organization rather than handling it solo.

Frequently asked questions

Do I have to register a single condo unit I rent out in DC?

Generally yes. DC's registration requirement under the Rental Housing Act applies to individual rental units, more than multi-unit buildings, though your specific exemption eligibility depends on factors like whether you own four or fewer units citywide. File Form RAD-1 with DHCD to register or claim an exemption rather than assuming a single unit is automatically excluded.

How much does DC rent registry cost per unit?

DC's registration fee is tied to the Basic Business License fee schedule and varies by unit count and license category. Because DHCD and DLCP periodically adjust these fees, confirm the current amount with DHCD or DLCP before budgeting, rather than relying on a fixed number that may be outdated.

What happens if I raise rent without registering my DC unit?

A tenant can petition the Office of Administrative Hearings challenging the increase as illegal, and unregistered status is often grounds to void rent increases retroactively. You may also owe the tenant back the overcharged amount. This is a much bigger risk than a simple late-filing fee.

How to become a landlord in DC from scratch?

Get the Certificate of Occupancy confirmed, apply for a Basic Business License through DLCP, register the unit (or file an exemption) with DHCD, determine rent control status, set up a compliant lease with required disclosures, and screen tenants consistent with DC's Human Rights Act. Skipping registration is the most common and costly mistake.

What is landlording, in plain terms?

Landlording is the ongoing, active work of renting out property: collecting rent, handling repairs, managing leases, and staying compliant with local licensing and habitability law. It's different from simply owning property because it involves continuous legal and operational responsibilities toward tenants.

What is a landlord legally responsible for?

A landlord is legally responsible for maintaining a habitable unit, following required notice rules for entry and rent increases, complying with local licensing and registration requirements, and following just-cause eviction rules where they apply, as DC's Rental Housing Act requires for covered units.

What rights does a tenant have without a signed lease in DC?

A tenant without a written lease in DC still has habitability rights, just-cause eviction protections, and, if the unit is registered and covered, protection from illegal rent increases. The lack of a written lease mainly weakens proof of specific terms like agreed rent, not the tenant's core legal protections.

Why do landlords require renters insurance if DC doesn't mandate it?

Renters insurance covers a tenant's belongings and personal liability, which the landlord's building insurance doesn't cover. Requiring it as a lease condition reduces disputes over who pays for tenant property damage or liability incidents, even though DC has no citywide law forcing tenants to carry it.

How much notice does a DC landlord have to give before an entry or rent increase?

For rent increases on rent-controlled units, DC generally requires at least 30 days' written notice before the increase takes effect, capped at the annually published CPI-based limit. For entry, DC doesn't set one fixed statutory number, but reasonable advance notice and legitimate purpose are the general standard.

Who is responsible for the rental walkthrough inspection in California, and how is that different from DC?

In California, routine rental inspections (where a city has adopted a program) are typically conducted by city or county code enforcement staff, not the landlord. DC relies more on complaint-driven inspections through DCRA/DOH rather than a routine citywide inspection cycle.

What can a landlord not do in Ohio?

Ohio landlords cannot shut off utilities to force a tenant out, change locks without a court order, retaliate against tenants who report code violations, enter without reasonable notice, or withhold a security deposit beyond 30 days without an itemized deduction list, under Ohio Revised Code Chapter 5321.

Can DHCD void my past rent increases if I never registered my DC rental unit?

Yes, this is a real risk. Because registration status determines rent control coverage, an unregistered unit can be treated as noncompliant, and a tenant may successfully challenge past rent increases through the Office of Administrative Hearings, potentially recovering overcharged rent.

Is DC rental registration the same as getting a Basic Business License?

No, they're related but separate. The Basic Business License through DLCP authorizes you to operate as a rental housing business, while the rental unit registration (or exemption claim) through DHCD specifically establishes the unit's rent control status under the Rental Housing Act.
