This guide provides a practical overview of some of the most What Buyers, Sellers, Landlords and Real Estate Investors Need to Know
important Washington, DC real estate laws and regulations affecting property owners, buyers, sellers, landlords, tenants, and real estate investors.
Important: This page is provided for general informational purposes and is not legal advice. Real estate laws and regulations can change, and individual transactions may have circumstances requiring advice from a qualified DC attorney or other appropriate professional.
1. Washington, DC Residential Property Seller Disclosure
Washington, DC requires a residential real property disclosure statement for certain residential transactions.
The District’s residential disclosure law generally applies to the sale or transfer of one-to-four-unit residential property when the purchaser has expressed in writing an intent to reside in the property.
The seller must provide the required disclosure statement before or at the time the prospective purchaser signs the purchase agreement.
What does the seller have to disclose?
The DC disclosure requirements address information actually known by the seller concerning a number of components and conditions of the property, including:
- Water and sewer systems
- Lead testing and lead-bearing plumbing
- Lead service lines
- Insulation
- Structural systems
- Roof, walls, floors, foundation and basement
- Plumbing
- Electrical systems
- Heating and air conditioning
- Rodent or wood-boring insect infestation history
- Appliances
- Alarm and intercom systems
- Garage door openers and remotes
- Fixtures
The law generally focuses on information actually known to the seller. A seller is not automatically required to discover defects that could only be identified through an inspection of inaccessible areas or specialized expertise beyond the seller’s knowledge.
Does a DC seller have to hire a home inspector?
Generally, the DC disclosure law does not require the seller to conduct a general home inspection simply to complete the seller disclosure.
However, buyers should strongly consider obtaining an independent home inspection.
A seller should never assume that a disclosure requirement eliminates the obligation to disclose a known material condition.
What if the seller doesn’t know the answer?
The DC law recognizes that some information may be unknown or unavailable to the seller. In appropriate circumstances, the seller may identify information as unknown rather than guessing.
The seller’s disclosures must be made in good faith.
2. TOPA – Tenant Opportunity to Purchase Act
One of the most important DC laws affecting the sale of residential rental property is the Tenant Opportunity to Purchase Act, commonly called TOPA.
TOPA can have a major impact on the timing and structure of a real estate transaction.
In general, TOPA gives qualifying DC tenants an opportunity to purchase their rental housing before the property is sold to another purchaser.
The law can apply to:
- Apartment buildings
- Multifamily properties
- Rental housing accommodations
- Certain individual rental properties
- Certain transfers of ownership interests
The exact requirements depend on the property, number of rental units, type of transaction, tenant circumstances, and applicable exemptions.
TOPA and multifamily properties
Owners of rental housing should determine whether TOPA applies before putting a property under contract.
For properties with five or more rental units, DC provides specific Offer of Sale and TOPA procedures.
The owner generally must provide tenants with the appropriate notice and allow the applicable statutory periods to run before completing the transaction.
TOPA changes under the RENTAL Act of 2025
The Rebalancing Expectations for Neighbors, Tenants, and Landlords (RENTAL) Act of 2025 became effective December 31, 2025.
Among other changes, the law:
- Allows DHCD to provide written certifications concerning receipt or non-receipt of TOPA notices
- Allows certain TOPA notices to be submitted electronically
- Creates a cooling-off period concerning assignment of TOPA rights in buildings with five or more units
- Formalizes Notice of Transfer requirements for certain transactions claimed to be exempt from TOPA
- Requires additional information in certain Notices of Transfer
- Places the burden on the owner to establish eligibility for a claimed TOPA exemption
- Creates a rebuttable presumption of a sale when a required Notice of Transfer is not provided or is materially misleading
Because TOPA can significantly affect a transaction, owners and purchasers of DC rental property should obtain professional advice before assuming that a particular transaction is exempt.
3. Lead-Based Paint Requirements
Lead-based paint is a particularly important issue in Washington, DC because of the age of much of the District’s housing stock.
For a dwelling constructed before 1978, DC law requires the owner to disclose reasonably known information concerning:
- Lead-based paint
- Lead-based paint hazards
- Certain pending government actions concerning lead
The required lead disclosure must be provided before the purchaser or tenant becomes obligated under the applicable purchase or lease contract.
Federal lead disclosure requirements
Federal law also imposes lead-based paint disclosure requirements for most residential properties constructed before 1978.
Therefore, a DC residential transaction involving an older property may involve both federal and District requirements.
Buyers should ask for available lead documentation and consider appropriate inspections or risk assessments when warranted.
4. Real Estate Broker and Agent Duties in Washington, DC
Washington, DC law establishes specific duties for licensed real estate brokers, salespersons and property managers.
A licensee representing a seller has duties that include:
- Acting according to the brokerage relationship
- Promoting the seller’s interests
- Presenting written offers and counteroffers in a timely manner
- Disclosing material facts concerning the property or transaction that the licensee actually knows
- Maintaining client confidentiality
- Exercising ordinary care
- Complying with applicable laws and regulations
A seller’s agent must also treat prospective buyers honestly and may not knowingly provide false information.
Importantly, a licensee representing a seller must disclose to prospective buyers material adverse facts concerning the physical condition of the property that are actually known to the licensee.
Disclosure of brokerage relationships
DC law also requires disclosure of brokerage relationships in applicable circumstances.
When a licensee has a substantive discussion about a specific property with a buyer or seller who is not the licensee’s client, the licensee generally must disclose the brokerage relationship at the earliest practical time and no later than when specific real estate assistance is first provided.
5. Washington, DC Fair Housing Laws
Federal and District fair housing laws prohibit discrimination in real estate transactions.
DC’s fair housing protections are particularly broad.
Protected characteristics under DC law include categories such as:
- Race
- Color
- Religion
- National origin
- Sex
- Age
- Marital status
- Sexual orientation
- Gender identity or expression
- Familial status
- Disability
- Source of income
- Family responsibilities
- Political affiliation
- Place of residence or business
- Homeless status
- Other characteristics protected by District law
Real estate professionals must be particularly careful when advertising property, screening prospective tenants or buyers, negotiating transactions, and communicating with the public.
6. Condominium Sales in Washington, DC
Selling a condominium involves additional considerations beyond those associated with a typical single-family home.
A prospective condominium purchaser should review the condominium association’s governing documents and financial information before purchasing.
Depending on the circumstances, important documents may include:
- Declaration
- Bylaws
- Rules and regulations
- Budget
- Financial statements
- Reserve information
- Insurance information
- Pending litigation
- Assessments
- Special assessments
- Meeting minutes
- Association disclosures
Buyers should carefully review condominium documents and understand their rights before the applicable contractual deadlines expire.
7. DC Rental Property Laws
Owners of rental properties in Washington, DC must comply with a separate collection of laws governing rental housing.
Depending on the property and circumstances, requirements may involve:
- Rental registration
- Housing inspections
- Building and housing codes
- Lead requirements
- Security deposits
- Rental agreements
- Notices to tenants
- Rent increases
- Rent control
- Tenant protections
- TOPA
- Eviction procedures
- Housing accommodations requirements
Owners should determine which requirements apply to their particular property before leasing, selling, renovating or changing the property’s use.
8. Rent Control in Washington, DC
Washington, DC has rent stabilization laws that may apply to certain rental properties.
Not every rental unit is subject to rent control, and exemptions can depend on factors such as the type of property, date of construction, ownership, registration and other statutory requirements.
Landlords should not assume that a property is exempt merely because it is privately owned.
Before increasing rent or changing the rental status of a property, owners should verify the property’s current registration and exemption status.
9. Buying or Selling a Multifamily Property
Multifamily transactions in Washington, DC require additional due diligence.
Before purchasing a multifamily property, an investor should consider:
Property and building issues
- Number of legal dwelling units
- Certificates of occupancy
- Building permits
- Zoning
- Housing code compliance
- Open violations
- Fire code compliance
- Lead requirements
- Environmental issues
- Utility arrangements
- Property condition
Tenant issues

Financial issues

- Property taxes
- Insurance
- Utilities

- Outstanding assessments
- Delinquent tenant balances
For larger rental properties, TOPA compliance should be reviewed early in the transaction rather than waiting until settlement.
10. Zoning and Permits
Washington, DC properties are subject to zoning and building regulations.
Before buying or selling a property, it can be important to verify:
- Current zoning classification
- Legal use
- Number of legal units
- Certificates of occupancy
- Building permits
- Additions and renovations
- Accessory dwelling units
- Conversion history
- Open permits
- Building violations
An investor should never assume that the current physical configuration of a property is necessarily its legally authorized use.
11. Property Taxes and Homestead Benefits
DC property owners may qualify for various property tax programs.
The Homestead Deduction, for example, can reduce the assessed value used to calculate property taxes for qualifying owner-occupied residential property.
Other programs may be available to qualifying homeowners depending on age, income, disability and other requirements.
Homeowners should verify their eligibility directly with the District government because eligibility requirements and application procedures can change.
12. Does Washington, DC Require a Radon Test?
Unlike some jurisdictions that impose a mandatory radon test as part of a residential sale, DC’s residential seller disclosure law does not establish a general requirement that every seller obtain a radon test before selling a home.
However, radon can be an important environmental consideration, particularly for properties with basements or lower levels.
A buyer may choose to include radon testing as part of the inspection and due-diligence process.
If a seller or real estate licensee has actual knowledge of a material condition that must be disclosed under applicable law, that issue should be addressed appropriately.
13. Does DC Require a Home Inspection?
There is generally no blanket requirement that every residential seller obtain a home inspection before listing a property.
However, a buyer can choose to have the property professionally inspected.
A typical buyer’s inspection may examine:
- Roof
- Foundation
- Structure
- Plumbing
- Electrical systems
- HVAC
- Water intrusion
- Basement
- Attic
- Appliances
- Exterior
- Drainage
- Safety issues
An inspection is different from the seller’s statutory disclosure obligations.
