# DC Council Eyes Pied-à-Terre Tax on Empty Mansions as Revenue Dries Up

Published on September 04, 2026

DC Council members are weighing a new tax on high-value homes owned by people who don't actually live in them full-time, adding a pied-à-terre surcharge to the city's toolkit as officials scramble to fill a widening revenue gap. The idea, still in the earliest stages of discussion, would layer an owner-occupancy test onto the District's existing high-value-home taxation rather than replace it.

The concept, first reported by UrbanTurf, has no formal bill number or sponsor yet, putting it well behind two other revenue proposals already moving through the legislative pipeline: a wealth proceeds tax and a land value tax, both of which already have formal bill numbers and sponsors attached. Council Chair Phil Mendelson has scheduled a council meeting for October 16 to debate these and other possible tax changes and increases, according to the same UrbanTurf report.

### Why DC Is Looking at New York's Playbook

The pied-à-terre concept draws directly from New York City, where Mayor Zohran Mamdani and Governor Kathy Hochul proposed a similar tax in May, and where the New York State Legislature approved the proposal that same month. As UrbanTurf's reporting lays out, New York's version applies to condos or co-ops assessed above $1 million where the owner's primary residence is elsewhere, while a related measure targets one- to three-family homes valued above $5 million under the same absentee-owner standard. City officials there project the tax will raise at least $500 million annually.

New York's rollout hasn't been clean, however. A city council oversight hearing aired complaints from homeowners who said they were mistakenly flagged for the surcharge, and the tax now faces ongoing litigation, per UrbanTurf's account. Those wrinkles offer a cautionary preview for DC officials considering a similar mechanism.

### Building on DC's Existing Mansion Tax

Any DC version wouldn't start from scratch. The Council enacted a mansion tax as part of the District of Columbia Fiscal Year 2025 budget legislation considered in 2024, creating a surcharge that adds $1 for every $100 of assessed value above a $2.5 million threshold, on top of the District's standard $0.85-per-$100 residential rate. Analysis from the D.C. Policy Center found that more than half of the revenue that tax generates comes from just three neighborhoods — Georgetown, Kalorama, and Massachusetts Avenue Heights — with Georgetown alone home to 515 qualifying properties.

DC already uses owner-occupancy as a lever for property tax relief in the opposite direction. For tax year 2026, the DC Office of Tax and Revenue set the standard Homestead Deduction at $91,950, which is subtracted from an owner-occupied primary residence's assessed value before taxes are calculated, according to the agency's published guidance. A pied-à-terre tax would essentially flip that logic, penalizing high-value homes that lack owner-occupied status rather than rewarding those that have it.

### A Shrinking Revenue Picture Adds Pressure

The timing isn't incidental. An independent forecast from the Office of the D.C. Auditor projected District tax revenue will decline from $12.2 billion to $11.8 billion for the fiscal year ending September 30, a drop the auditor's office tied to job losses, commercial real estate devaluations, and federal spending cuts, as reported by the Washington Times. Declining commercial property values and transactions are also affecting tax collections, adding pressure to find new sources elsewhere.

That backdrop follows a bruising fight over the current budget. Mayor Muriel Bowser refused to sign the District's fiscal year 2027 budget and sent Mendelson a warning letter arguing that using one-time funding for recurring programs would create an $837 million fiscal cliff for future city leaders, as Hoodline reported in a July story on the standoff. The Council, meanwhile, has restored or increased funding for childcare and housing vouchers amid the budget debate.

### Competing Tax Bills and Business Pushback

Councilmember Brianne K. Nadeau has introduced a Wealth Proceeds Tax proposal, which would impose a 3% surcharge on passive income, according to Nadeau's office. That proposal has already drawn concern: the Greater Washington Board of Trade and a coalition of regional business groups issued a joint letter raising concerns about the competitiveness effects of new levies and the challenge of attracting investment.

Any tax the Council does pass also faces a federal hurdle. The U.S. House Committee on Oversight and Accountability has passed legislation that would require explicit, affirmative approval from both the House and Senate before any D.C. Council tax change could take effect, according to FOX 5 DC. Hoodline has previously covered related congressional efforts to nullify local tax revisions and preserve federal-level control over the District's tax code, including in coverage of a tax refund fight on Capitol Hill.

### Push for Public Input at the October Hearing

Meanwhile, advocates for housing vouchers and childcare funding are pressing the Council as it weighs which of these competing revenue proposals, including the still-undefined pied-à-terre tax, to advance before next spring's budget season.
