Washington, D.C., would impose additional property tax on homes worth about $2.6 million or more that are not rented out or used as primary residences under legislation before the district council. The proposal, reported September 23, targets high-value properties that function as second homes or remain unoccupied.

The so-called pied-à-terre tax would apply only to properties that fail to qualify as either primary residences or rental units. Properties used as a principal dwelling or leased to tenants would remain exempt from the additional levy.

The legislation comes as state and local governments look for new revenue sources from high-value real estate holdings. The $2.6 million threshold would limit the tax's reach to a narrow segment of the District's residential property market.

The measure is currently before the district council. No timeline for a vote or details on the proposed rate structure have been disclosed.

Other jurisdictions have explored similar levies in recent years. The District's proposal joins a broader trend of targeting second homes and vacant properties with incremental taxes designed to raise revenue without broadening the base to owner-occupied housing.

The Deployment Angle

Family Office Real Estate Daily Desk · our analysis, not the source's

Family offices with District holdings above the $2.6 million line should immediately flag any property that neither houses a principal nor generates rental income. The incremental tax changes the arithmetic on carrying cost — run the numbers on whether a long-term lease to a third party, even at below-market rent, delivers a better after-tax return than accepting the additional levy.

If the property serves as occasional lodging for family members or executives, model whether converting it to a documented primary residence for one family member avoids the tax. That requires genuine domicile — voter registration, utility bills, time spent in the District — not a paper change of address. The compliance burden may exceed the tax savings for properties used a few weeks per year.

For properties held in trusts or LLCs, confirm that the ownership structure does not complicate the primary-residence exemption. Some pied-à-terre taxes at the state level have turned on whether the beneficial owner occupies the home, not the title-holding entity. If the District adopts similar language, plan for restructuring before the tax takes effect.

If the portfolio includes multiple District properties, consider consolidating occupancy and disposing of the units that generate the least utility. A $3 million pied-à-terre with minimal use becomes harder to justify if the annual tax increment runs into five figures. The market for high-end District resales may soften if other holders reach the same conclusion, so evaluate exit timing now rather than after the tax is law.
