Trigger — Any tenant/occupant: TOPA
[SELLER]. APPEARS: Municipal certificate obtained pre-closing. Tenant Opportunity to Purchase Act, D.C. Code § 42-3404.01 et seq. TOPA gives qualifying tenants notice and (in multi-unit buildings) an opportunity to purchase / right of first refusal, converting tenant-occupied sales into a multi-month process. Response/negotiation periods scale with building size (single-family: notice only; 2–4 units and 5+ units carry longer periods, with 5+ units also carrying extended contract/financing windows).
- Recent change (single-family): the TOPA Single-Family Home Exemption Amendment Act of 2018, D.C. Law 22-120 (from Bill 22-0315), exempts single-family accommodations — including a single-family home with an accessory dwelling unit, and a single rental unit in a condo/co-op/HOA — from the opportunity-to-purchase/right-of-first-refusal, but tenant NOTICE is still required. Elderly (62+) or disabled tenants who signed a lease by March 31, 2018 and took occupancy by April 15, 2018 retain limited purchase/assignment rights. On the single-family track, the owner delivers Form 1 (Notice of Intent to Sell) to each tenant, plus the Office of the Tenant Advocate (OTA) and DHCD, via trackable delivery; the tenant has 20 days to respond.
- Recent change (major): the Rebalancing Expectations for Neighbors, Tenants, and Landlords (RENTAL) Act of 2025 significantly amended TOPA (effective December 31, 2025), including a 15-year exemption for multifamily buildings measured from certificate-of-occupancy issuance (with retroactive effect), retroactive new-construction exemptions (buildings built 2010–2025), and covenant-based exemptions (buyer covenants that 51% of units stay affordable at 80% AMI for 20 years). A Notice of Transfer is still required for exempt buildings, and tenants have 45 days to register a tenant association to contest. This area is in flux and subject to congressional review — verify current mechanics and forms with DHCD/OTA.

Trigger — Pre-1978 structure: DC lead
[SELLER]. DC Lead Hazard Prevention and Elimination Act, D.C. Code § 8-231.01 et seq. (amended 2010, effective March 31, 2011). The DC lead-disclosure obligation (§ 8-231.04) layers atop federal Title X; owners must disclose known lead-based paint/hazards and any pending Mayor's orders on the DC lead-disclosure form (which incorporates the federal Lead Warning Statement per 24 C.F.R. §§ 35.90/35.92 and 40 C.F.R. § 745.107). DC law makes lead-based paint hazards illegal in pre-1978 residential units and imposes a somewhat higher disclosure obligation than the federal baseline.
