Quick Reference: D.C. Registration Requirements at a Glance

A property manager takes on a four-unit building in Petworth owned by a single individual who owns nothing else in the District. It plainly meets the substantive conditions for the small-provider exemption. She sets a market rent, signs a tenant, and files nothing, because the building is exempt.

That reasoning skips a critical compliance step: meeting the substantive conditions for an exemption and satisfying the District's registration and exemption-claim requirements are not necessarily the same thing.

The small-provider exemption in § 42-3502.05(a)(3)(C) is expressly conditioned on the provider filing a claim of exemption statement with the Rent Administrator, consisting of an oath or affirmation and containing the signatures of each person having a direct or indirect interest in the housing accommodation. RAD also requires exemption claims to be supported by documentation.

And the District's own position on unfiled units is blunt. The DC Rent Registry states that all unregistered units are rent-stabilized unless RAD approves an exemption. Add the $100 per unit penalty under § 42-3502.05(f)(4)(B)(i), and the cost of failing to follow the registration or exemption-filing requirements applicable to the accommodation becomes clear.

Registration is also not the same thing as your business licence, and the two do not always happen in the same order.

Step 1: Two Filings, and the Sequence Depends on Your Property Type

The most common structural error is treating the Basic Business Licence as the whole of D.C. rental compliance.

The licence. Operating rental housing in the District requires a Basic Business Licence with the appropriate rental housing endorsement, administered by the Department of Licensing and Consumer Protection. DLCP distinguishes three residential categories: one-family rental, covering single-family homes, townhouses, duplexes, individual condominium units and individual rooms; two-family rental, covering an English basement apartment, converted basement apartment or carriage house where the main residence is occupied by the owner or another tenant; and apartment, covering buildings with three or more dwelling units.

The registration. Separately, § 42-3502.05 requires housing providers to register with the Rental Accommodations Division, and that registration is where rent stabilization status or an exemption claim is recorded.

And the order runs differently by category. According to DLCP's Rental Accommodations Registration Form Details, an applicant for an Apartment must register with DHCD after the Basic Business Licence has been accepted by DLCP, then return to DLCP with the DHCD-stamped RAD Form in order for the licence to be issued. One Family Rental and Two Family Rental applicants must register with DHCD after the licence has been issued.

So there is no single "licence first, registration second" rule. The applicable sequence depends on the rental housing category and the District's current DLCP and RAD workflow, and managers should follow the sequence for their category rather than assuming one order applies across a mixed portfolio.

What the statute requires either way. Under § 42-3502.05(f)(3)(B), a registration for an accommodation required to obtain a housing business licence must state the dates and numbers of the housing business licence and the certificates of occupancy, and include a copy of each. Under (f)(3)(C), an accommodation not required to obtain one still supplies certificate of occupancy dates, numbers and copies.

Holding those documents on the property record rather than in an email chain is what makes a filing possible on the day it is due, which is the case for keeping property-level compliance documents alongside the tenancy record through contracts and renewals.

Step 2: The Rent Registry, and the Deadlines That Run From It

Subsection (f) is drafted around the completion of a database rather than a fixed calendar date, which is why published deadlines have shifted.

The re-registration duty. Under § 42-3502.05(f)(1), within 90 days after completion of the publicly accessible rent control housing database created under § 42-3502.03c, each housing provider receiving or entitled to receive rent shall file a new registration statement and, if applicable, a new claim of exemption via the online housing provider portal.

Read "new." This was not a first-time duty for landlords already on file under the old paper system. It required re-filing through the portal, including for units claimed as exempt.

The new-provider duty. Under (f)(2), a person who becomes a housing provider 90 days or more after completion of the database shall file a registration statement and, if applicable, a claim of exemption, within 30 days after becoming a housing provider.

For housing providers entering the system after that threshold, the operational deadline is thirty days from becoming a housing provider. Existing providers should separately confirm whether any registration, re-registration, correction or updated filing obligation applies to their accommodation.

Every transaction in which a person becomes the housing provider should trigger a review of that 30-day requirement. Property management firms should also review whether a change in their management role affects the statutory housing-provider or registration obligations for the accommodation, since whether a third-party manager becomes the statutory housing provider depends on the structure and the facts.

An amnesty, then a penalty. Under (f)(4)(A), no penalties for failure to previously register may be assessed against a provider who registers within the 90-day window. Under (f)(4)(B)(i), beginning 91 days after completion of the database, a provider other than the federal government who fails to register shall pay a penalty of $100 per unit, deposited into the Rental Housing Registration Fund under § 42-3502.03e.

And a rent increase block. Under (f)(4)(B)(ii), a housing provider other than a housing provider exempt pursuant to subsection (a) who does not timely register may not institute a rent increase authorised by § 42-3402.08(a) until the housing provider registers and pays any associated penalty.

Note the wording carefully. That restriction is written for non-exempt providers. But the DC Rent Registry's position is that all unregistered units are rent-stabilized unless RAD approves an exemption, so a provider who has filed nothing is in a weak position to establish which side of the line they sit on.

Because the deadline runs from an event rather than a date, and a thirty-day clock attaches to becoming a housing provider, the trigger has to be captured at the point of acquisition. Building that as a dated step with an owner attached through workflow customization is what prevents a thirty-day filing being discovered at day forty.

Step 3: What the Registration Statement Must Contain

Section 42-3502.05(f)(3) sets out the required information in tiers, and the non-exempt tier is heavier than most managers expect.

For all housing accommodations, (f)(3)(A):

• Address of the housing accommodation;

• Type of housing accommodation;

• Number of bedrooms in each unit; and

• Property owner's business information.

For non-exempt accommodations, (f)(3)(D), four further items:

• The current rent charged for each rental unit, the related services included, and the related facilities and charges;

• The current related and optional services and facilities provided as part of rent or the rental agreement;

• A list of any outstanding violations of the housing regulations applicable to the accommodation, or an affidavit stating that the provider duly inspected the accommodation within the 6 months prior to filing and that there are no outstanding violations known to the provider; and

• The rate of return for the housing accommodation and the computations made to arrive at it, by application of the formula in § 42-3502.12.

That third item is a real operational requirement. You either list outstanding housing code violations or swear you inspected within six months and know of none. A provider with no recent inspection record can do neither comfortably.

And the fourth is a financial calculation, not a form field. The hardship petition formula in § 42-3502.12 requires the accommodation's income and expenses, so the registration cannot be completed from the leasing file alone.

For exempt accommodations, (f)(3)(E): the date on which each unit first became exempt, and the rent charged for the period of tenancy immediately preceding the first exemption.

That is a historical figure, sometimes decades old, which is why acquiring a building without its registration history is a problem you inherit.

Because the non-exempt filing requires a violations position and a rate of return, the registration depends on inspection records and property-level financials being current. Dated inspection history through move-in and move-out management, and income and expense visibility per property through dashboards and reports, are what make the filing assemblable rather than reconstructable.

Step 4: The Extra Data Exempt Owners Supply, Once

Subsection (f)(5) is short and worth knowing precisely because of what it does not require.

The owner of a rental accommodation exempt under subsection (a) shall, at the time of registration, provide for each rental unit:

• The current monthly rent amount;

• The monthly rent amount charged for the same unit during each of the 2 prior calendar years; and

• The utilities, facilities and services, and appliances.

And then the limit. Under (f)(5)(B), that information shall be submitted only at the time of registration and shall not be subject to any ongoing or annual reporting requirements.

So exempt owners give two years of rent history at the point of filing, and nothing recurring. That is meaningful reassurance for owners who assumed registration would create an annual burden, and it is a reason to keep rent history retrievable per unit rather than only in the current ledger, which is what collecting rent and payments records are for.

Step 5: The Exemptions, and the Conditions Attached

Subsection (a) lists the exemptions from the rent stabilization provisions. Each has conditions, and two require a filed and signed claim. RAD requires all exemption claims to be supported by documentation, and the documentation differs by category.

Federal or District-owned or subsidised, (a)(1). Including units where the mortgage or rent is federally or District-subsidised, certain home and community-based services waiver units occupied by a tenant with a disability, and units for which the provider receives Low-Income Housing Tax Credits. Note that the DC Rent Registry states federally-owned and District-owned rental units are not required to be registered, while subsidy-based exemptions are supported by documentation such as an executed subsidy agreement or recorded covenant.

New construction, (a)(2). Any unit in an accommodation for which the building permit was issued after 31 December 1975, or any newly created unit added to an existing structure and covered by a certificate of occupancy for housing use issued after 1 January 1980. The proviso matters: the exemption does not apply where construction required demolishing an accommodation subject to the chapter, unless the number of newly constructed units exceeds the number demolished.

Small providers, (a)(3). Any unit in an accommodation of 4 or fewer rental units, including an aggregate of 4 whether in the same structure or not, provided:

• The accommodation is owned by not more than 4 natural persons;

• None of the housing providers has an interest, either directly or indirectly, in any other rental unit in the District;

• The provider files a claim of exemption statement with the Rent Administrator, consisting of an oath or affirmation, containing the signatures of each person having a direct or indirect interest; and

• Any change in ownership or in the provider's interest in another accommodation that would invalidate the claim must be reported in writing to the Rent Administrator within 30 days.

Two carve-outs sit inside it. The natural-persons limitation does not apply to an accommodation owned or controlled by a decedent's estate or testamentary trust if it was already exempt at the time of death. And for condominium units, the accommodation is the aggregate of the condominium rental units and any other rental units owned by the natural persons claiming the exemption.

Continuously vacant, (a)(4). Any accommodation continuously vacant and not subject to a rental agreement since 1 January 1985, provided that on re-rental it is in substantial compliance with the housing regulations when offered for rent.

Cooperatives, (a)(5). Units in a structure owned by a cooperative housing association where the proprietary lease is owned by not more than 4 natural persons who are shareholders or members, none holding an interest in more than 4 D.C. rental units, with the same signed claim of exemption statement and 30-day change reporting requirements.

Building improvement plans, (a)(7). Accommodations under an executed building improvement plan or receiving DHCD multi-family rehabilitation assistance, on conditions including a certification signed by tenants of 70% of the occupied units filed at execution.

And a TOPA trap. Under § 42-3502.05(a-1), a housing provider who comes into possession through a transfer under § 42-3404.02(c)(2) is eligible for the small-provider exemption only if the provider was eligible for the exemption at the time of the transfer. That connects registration directly to the tenant purchase framework covered in our guide to D.C.'s Tenant Opportunity to Purchase Act.

Also note (a-2). A rental unit subject to a tax exemption under § 47-1005.03 becomes subject to the registration and rent stabilization provisions after the expiration or termination of the tax exemption, regardless of whether it would otherwise qualify under subsection (a).

Step 6: Four Categories Outside the Chapter Entirely

Subsection (e) is different from subsection (a). These are not exemptions from rent stabilization; the chapter does not apply to them at all:

1. Any rental unit operated by a foreign government as a residence for diplomatic personnel;

2. Any rental unit in an establishment whose primary purpose is providing diagnostic care and treatment of diseases, including hospitals, convalescent homes, nursing homes and personal care homes;

3. Any dormitory; and

4. Following a determination by the Rent Administrator, any unit intended for use as long-term temporary housing by families, meeting three conditions: occupancy by families with incomes at or below 50% of District median income for the size in question for the preceding 12 months; a nonprofit charitable provider operating strictly not-for-profit; and a comprehensive social services programme offered to resident families.

The distinction matters. Many exemptions under subsection (a) operate within the District's registration framework and may require registration information and a claim of exemption. By contrast, subsection (e) identifies categories to which the chapter does not apply. Housing providers should confirm the filing treatment for their specific exemption category with RAD.

Step 7: The Ongoing Duties, and Who Is Excused

Registration is not the end of the obligation, but the ongoing duties fall unevenly.

The 30-day notices, (g)(1). A housing provider shall file with the Rent Administrator:

• A copy of the rent increase notice given under § 42-3502.08(h)(2), within 30 days after the effective date. Where increases go to multiple tenants with the same effective date, a sample notice plus a list of unit number, tenant name, previous rent charged, new rent charged and effective date;

• A copy of the notice given under § 42-3502.13(d) stating the calculation of the initial rent charged in the lease, based on increases during the preceding 3 years, within 30 days of the commencement of the lease term; and

• Notice of a change in ownership or management of the accommodation, or a change in the services and facilities included in the rent charged, within 30 days after the change.

For accommodations subject to subsection (g), a change in management therefore requires notice to the Rent Administrator within 30 days after the change. Qualifying exempt units are excused from subsection (g).

The posting duty, (h)(2). Each housing provider shall keep a duplicate of the registration statement posted in a public place on the premises. For a single-unit accommodation, the provider may instead mail a duplicate to the tenant.

Both duties fall away for qualifying exempt units. The opening words of subsection (a) exempt qualifying units from subsections (g) and (h)(2) and from §§ 42-3502.06 through 42-3502.16, 42-3502.18 and 42-3502.19. For qualifying exemptions that remain within the registration framework, the provider files the required registration information and claim of exemption, but qualifying exempt units are generally excused from the subsection (g) notice duties and the posting duty in subsection (h)(2). Federally owned and District-owned units have separate treatment under the DC Rent Registry guidance.

One duty applies specifically to exempt units, though. Under § 42-3502.05(d), prior to the execution of a lease, a prospective tenant of a unit exempted under subsection (a) shall receive a notice in writing advising that rent increases for the accommodation are not regulated by the rent stabilization program. That is a pre-lease disclosure and belongs in the leasing pack rather than the compliance file.

And when an exemption ends, (g-1). After the expiration or termination of an exemption, the provider shall file, upon the re-renting of the unit, an amended registration statement including the rent charged calculated under § 42-3502.09, with the documentation supporting the calculation. The subsection (h)(2) notice requirements apply to that amended statement.

Because these duties turn on events rather than dates, and one is triggered by a management change, the compliance calendar has to be driven off the tenancy and property records. Connecting lease commencement, rent changes and management transitions to a single record, as a Tenant 360 View approach does, is what makes a 30-day notice reliable.

Step 8: A Section Currently Running on Temporary Legislation

One thing every manager relying on this section should know.

The version of § 42-3502.05 in force includes amendments made by temporary legislation scheduled to expire on 22 January 2027. The section has been amended repeatedly and recently, including by D.C. Law 26-111 in April 2026 and D.C. Law 26-136 in June 2026, the latter being the Rental Housing Registration Data Integrity Temporary Amendment Act of 2026. There have also been emergency acts on registration extension, LIHTC exemption clarification and registration data integrity.

The practical consequence is that provisions added through temporary legislation may change, expire, or be replaced by permanent legislation. Property managers relying on recently amended registration requirements should check the current version of the Code before filing, and compare it against the permanent version the D.C. Law Library publishes separately.

Common D.C. Registration Mistakes Property Managers Make

1. Assuming a qualifying building needs no filing
Meeting the substantive conditions and satisfying the filing requirements are not the same thing. The small-provider and cooperative exemptions require a signed claim of exemption statement.

2. Treating the Basic Business Licence as the whole requirement
The licence and the RAD registration are separate filings, and (f)(3)(B) requires licence and certificate of occupancy numbers and copies inside the registration.

3. Assuming one licensing sequence across a mixed portfolio
Apartment applicants register with DHCD after the BBL is accepted and return with a stamped RAD form; one-family and two-family applicants register after the licence is issued.

4. Missing the 30-day new-provider clock
Under (f)(2), a person becoming a housing provider files within 30 days.

5. Not reviewing filings after a management change
Under (g)(1)(C), notice of a change in ownership or management is due within 30 days for accommodations subject to subsection (g).

6. Underestimating the consequences
$100 per unit under (f)(4)(B)(i), the (f)(4)(B)(ii) restriction on rent increases for non-exempt providers, and the Rent Registry's position that unregistered units are rent-stabilized unless RAD approves an exemption.

7. Filing an exemption claim without documentation
RAD requires all exemption claims to be supported by documentation, and the required documentation differs by category.

8. Attempting the non-exempt filing without inspection records
Subsection (f)(3)(D) requires either a list of outstanding housing regulation violations or an affidavit of inspection within the prior six months.

9. Overlooking the rate of return requirement
Non-exempt registrations require the rate of return and the computations under the § 42-3502.12 formula.

10. Claiming the small-provider exemption without the signed statement
Section 42-3502.05(a)(3)(C) requires signatures of each person with a direct or indirect interest.

11. Forgetting the 30-day exemption change report
Any change invalidating the claim must be reported in writing to the Rent Administrator within 30 days.

12. Missing the demolition proviso on new construction
The (a)(2) exemption does not apply where construction required demolishing a covered accommodation, unless the new units exceed the demolished ones.

13. Assuming a TOPA transferee inherits the small-provider exemption
Under (a-1), eligibility depends on the provider having been eligible at the time of the transfer.

14. Omitting the pre-lease exemption notice
Under (d), a prospective tenant of an exempt unit must receive written notice before lease execution that rent increases are not regulated.

15. Not filing an amended statement when an exemption ends
Under (g-1), it is due upon re-renting, with the § 42-3502.09 calculation and supporting documentation.

16. Relying on a provision without checking its status
The section currently includes temporary amendments scheduled to expire 22 January 2027.

Conclusion

D.C. registration is the compliance step most likely to be skipped and the one that quietly disables everything else.

• Qualifying for an exemption and claiming one are different things. The small-provider and cooperative exemptions each require a signed claim of exemption statement and 30-day reporting of any change that would invalidate it, and RAD requires exemption claims to be supported by documentation. Filing treatment varies by category, so confirm yours with RAD.

• Two systems, and the order depends on the category. Apartment applicants register with DHCD after the BBL is accepted and return with a stamped RAD form for issuance; one-family and two-family applicants register after the licence is issued.

• The consequences are structural, not just financial. $100 per unit, a bar on rent increases for non-exempt providers until registered with any penalty paid, and the Rent Registry's position that unregistered units are rent-stabilized unless RAD approves an exemption.

• And the ongoing duties fall unevenly. Qualifying exempt units are generally excused from the 30-day notices in subsection (g) and the posting duty in (h)(2), but they carry the pre-lease written notice under (d) that rent increases are unregulated.

For teams managing District portfolios, the registration file is built from property records rather than tenancy records: the licence, the certificate of occupancy, the inspection history, the rent history per unit going back two calendar years, the exemption documentation, and the ownership structure that supports or defeats a claim. None of that can be assembled in the thirty days after an acquisition unless it was already being kept.

This blog is for informational purposes only and does not constitute legal advice. D.C. rental housing registration sits at D.C. Official Code § 42-3502.05 within the Rental Housing Act of 1985, with the housing provider portal and public database at § 42-3502.03c and the Rental Housing Registration Fund at § 42-3502.03e. The version of § 42-3502.05 currently in force includes amendments made by temporary legislation scheduled to expire on 22 January 2027, and the section was recently amended by D.C. Law 26-111 (April 2026) and D.C. Law 26-136 (June 2026); a permanent version is published separately by the D.C. Law Library. Registration and exemption filing treatment varies by category, and statements attributed to the DC Rent Registry reflect that agency's published guidance rather than statutory text; confirm the requirement for your category with the Rental Accommodations Division. Basic Business Licence requirements are administered by the Department of Licensing and Consumer Protection and are not set out in § 42-3502.05; confirm current licence categories, fees, inspection requirements and agency sequencing directly with DLCP. Eviction requirements, including the rental housing licence documentation required at the writ stage under § 42-3505.01(q), are addressed separately. Verify the current statutory text with the Council of the District of Columbia and confirm filing requirements with the DC Rent Registry. Consult a licensed D.C. attorney on any specific question.

Frequently Asked Questions

Q1. Do exempt rental units have to register in D.C.?
Generally the registration framework requires housing providers to file registration information and, where applicable, a claim of exemption. Treatment varies by category: the DC Rent Registry states that federally-owned and District-owned rental units are not required to be registered. Confirm the requirement for your specific exemption category with RAD.

Q2. Is registration the same as the Basic Business Licence?
No. They are separate filings, and the registration under § 42-3502.05(f)(3)(B) requires the housing business licence and certificate of occupancy dates, numbers and copies.

Q3. Which comes first, the licence or the registration?
It depends on the category. DLCP states that apartment applicants register with DHCD after the BBL is accepted and return with the stamped RAD form for the licence to be issued, while one-family and two-family applicants register after the licence has been issued.

Q4. How long does a new housing provider have to register?
Thirty days after becoming a housing provider, under § 42-3502.05(f)(2).

Q5. What happens if a unit is not registered?
Under § 42-3502.05(f)(4)(B)(i) a penalty of $100 per unit applies, with the federal government excepted, and under (f)(4)(B)(ii) a non-exempt provider may not institute a rent increase until registered and any penalty paid. The DC Rent Registry states that all unregistered units are rent-stabilized unless RAD approves an exemption.

Q6. What extra information do exempt owners provide?
Under § 42-3502.05(f)(5)(A), the current monthly rent, the monthly rent for the same unit in each of the two prior calendar years, and the utilities, facilities, services and appliances. Under (f)(5)(B) that is a one-time submission with no ongoing reporting.

Q7. What qualifies for the small-provider exemption?
Four or fewer rental units owned by not more than four natural persons, none of whom has a direct or indirect interest in any other D.C. rental unit, supported by a signed claim of exemption statement, with any invalidating change reported within 30 days.

Q8. What notice do tenants of exempt units receive?
Under § 42-3502.05(d), prior to execution of the lease, a prospective tenant of an exempt unit must receive written notice that rent increases for the accommodation are not regulated by the rent stabilization program.
