TOPA DC Explained: Timelines, Exemptions, and Waivers for Investors

You go under contract on a tenanted four-unit rowhouse in Columbia Heights. Your agent mentions, almost as an afterthought, that you need to "account for the TOPA process." You have no idea what that means. Six months later, the tenants have not purchased the building, but they also have not signed a waiver — and their attorney has been requesting floor plans, utility bills, and operating statements to drag the 90-day negotiation clock forward one day at a time. Your hard money loan is burning 12% interest. The seller is starting to talk about pulling the listing.

This is the Tenant Opportunity to Purchase Act (TOPA) in practice.

What TOPA Does and Why It Exists

TOPA — the Rental Housing Conversion and Sale Act of 1980 — grants tenants in DC rental properties a statutory right of first refusal before an owner can sell to a third-party investor. The theory is straightforward: if you are being displaced from your home because the landlord is selling, you should have the first chance to buy it and stay.

Before an owner can legally close with any third-party buyer, they must issue a formal Offer of Sale to the tenants. This document discloses the sale price, the terms, and the tenants' rights under the statute. The clock starts from the date the tenant receives a valid Offer of Sale. Everything that follows is driven by statutory timelines that vary significantly depending on the property size.

Single-Family Properties: The 2018 Exemption

Before 2018, TOPA applied to every rental property in DC, including single-family homes. This created a specific dysfunction: tenants of single-family homes rarely had the capital to purchase, so instead they used the statutory timelines as leverage to extract cash buyouts from sellers and investors — sometimes $20,000 to $50,000 just to sign a waiver.

The TOPA Single-Family Home Exemption Amendment Act, effective July 3, 2018, resolved this. Single-family dwellings — including individual houses and individually deeded condominium units — are now generally exempt from TOPA. The standard Offer of Sale process does not apply.

However, a critical carve-out survives: elderly tenants (age 62 or older) and tenants with qualifying disabilities who signed a rental agreement on or before March 31, 2018, and took occupancy by April 15, 2018, retain their full TOPA rights for the duration of their tenancy.

This means that before you assume a single-family property is TOPA-exempt, you need to verify three things about any existing tenant: their age, any disability status, and the exact date their lease was signed. A tenant who has lived in a Georgetown rowhouse since 2015 and turned 62 last year may have full TOPA rights — and their rights do not expire when their lease renews. They hold TOPA rights for the life of their tenancy in that unit.

Even for properties that are fully TOPA-exempt, DC law still requires the seller to notify the tenant in writing that the property is being marketed for sale.

TOPA Timelines for 2-to-4 Unit Properties

For small multifamily buildings with two to four units, TOPA applies in full. When the owner issues a valid Offer of Sale, the following cascade of timelines begins:

Days 1–15: The tenants can submit a written statement of interest in purchasing the property jointly. If no joint statement is delivered, any individual tenant has an additional 7 days to express individual interest.

22-day cooling-off period: Tenants in 2-to-4 unit buildings cannot assign their TOPA rights during the first 22 days after receiving a valid Offer of Sale unless they have received formal legal and financial training from an approved tenant advocacy organization.

90-day negotiation period: If tenants express interest, a mandatory 90-day negotiation period begins. During this time, the owner must negotiate in good faith. Crucially, the clock extends by one day for every day the landlord fails to deliver requested operational information (utility bills, floor plans, rent rolls) within seven days of a tenant request. A landlord who is slow with paperwork can accidentally add weeks to the 90-day period.

15-day right of first refusal: If the 90-day negotiation concludes without a contract, the tenant retains a 15-day right of first refusal on the third-party investor's executed contract. During this window, the tenant can step into the investor's shoes and match all material terms of the deal.

45–75 days to close: If a purchase contract is executed between tenant and owner, the tenant has at least 45 days to proceed to settlement, extendable to 75 days if a lender provides written confirmation that additional time is required.

Realistic total exposure on a 2-to-4 unit property with tenants who invoke their rights but ultimately do not purchase: four to six months of holding costs, hard money interest, and deal uncertainty.

TOPA Timelines for 5+ Unit Properties

The timelines expand dramatically for larger buildings. When an Offer of Sale is issued on a property with five or more units, tenants have 45 days to formally organize as a non-profit entity and register with the DHCD (30 days if a tenant association already exists). During this period, TOPA rights cannot be assigned to third parties without approved training.

Once registered, the tenant association receives a minimum 120-day negotiation period. Like the 2-4 unit process, this 120-day clock extends day-for-day for every day the owner delays providing requested property information.

If the tenant association executes a contract with the owner, they then receive a minimum of 120 days to secure financing and close, extendable up to 240 days with written confirmation from a lender.

Worst-case scenario on a 5+ unit building: if 360 days pass from the original Offer of Sale and no sale has closed, the entire TOPA process restarts from scratch. An investor can watch their capital locked in a contingent contract for over a year, and then face the prospect of starting the process over.

TOPA Waivers and Tenant Buyouts

The most practical mechanism for navigating TOPA is direct negotiation with the tenants before or shortly after the Offer of Sale is issued.

In a TOPA waiver, the tenant formally acknowledges their statutory rights and agrees in writing to waive them, clearing the path to closing with the third-party investor. In a buyout, the tenant receives a negotiated cash payment — commonly $10,000 to $30,000 depending on tenure and leverage — in exchange for assigning their TOPA rights or agreeing to vacate.

The assignability of TOPA rights is a significant investor risk. Tenants are legally permitted to assign their TOPA rights to third-party entities, including competing developers. A tenant facing a buyout offer from an investor may instead assign their rights to a competing developer who will use every available statutory day to delay the original sale — not because they plan to buy, but to force the seller to choose between waiting months and paying a larger buyout.

The RENTAL (Rebalancing Expectations for Neighbors, Tenants, and Landlords) Act of 2025 directly addressed this abuse by introducing a mandatory 45-day cooling-off period during which tenants cannot assign their rights, and by restricting the ability of third-party assignees to further assign those rights for consideration. The Act also exempted most two-to-four unit properties from TOPA when owned by individual landlords who own no more than two housing properties in the District.

Buildings Constructed After 2010

The RENTAL Act also confirmed a significant exemption for newer construction: buildings constructed between 2010 and 2025 are retroactively exempt from TOPA, and new construction going forward is exempt for the first 15 years of the building's life. This substantially increases the premium on post-2010 inventory for investors who want predictable closing timelines.

What Every Investor Must Do Before Going Under Contract

Before placing an offer on any tenanted DC property, collect the following during due diligence:

• Copies of all existing leases, including move-in dates and any addenda
• Tenant ages and any documented disability status (relevant for single-family exemption carve-outs)
• Confirmation of whether any prior TOPA notices have been issued on the property
• Status of any existing TOPA waivers or assignments
• For 5+ unit buildings: whether an active tenant association is registered with DHCD

Buying a tenanted DC property without understanding the specific TOPA exposure is one of the most expensive mistakes investors make. A deal that pencils at a 5.2% cap rate can become catastrophically underwater when six months of hard money interest, holding costs, and property taxes eat into the margin while the statutory clock runs.
