Can you find out who owns it?
Title in Washington, DC passes by deed recorded with the Recorder of Deeds, part of the Office of Tax and Revenue, which keeps 'all official records about land and property' and collects recordation and transfer tax (1.45% each on most transfers) when deeds are filed. The OTR tax roll, the Integrated Tax System Public Extract, names the owner, assessment and last sale price and date for every tax lot, and DC republishes it as open data under CC BY 4.0. Deed images back to 1921 are on a private portal where registered users search and view free and pay $4 to download a document.

The marquee buildings
The towers that set the tone of the core, and who holds them. A price is the price a document states, on the date it states — not an estimate of what the building is worth now.
| Building | Use | Owner | Owner type | Last price paid |
|---|---|---|---|---|
| The Wharf (Southwest Waterfront) Maine Avenue and Water Street SW, Square 473 3.2M+ sq ft planned on 27 acres plus 50 acres of water (2014 report) |
Mixed use | District of Columbia (land); Hoffman-Madison Waterfront 'Wharf … REIT Leaseholder' and 'Wharf … Condo Owner' LLCs (buildings) District holds the fee; buildings held by leasehold LLCs The roll names the District of Columbia as owner, alone or jointly, on 175 Wharf lots, with the buildings held in some 30 LLCs named 'Wharf Phase 1 Apartment REIT Leaseholder', 'Wharf 1 Office REIT Leaseholder', 'Wharf 3B Hotel REIT Leaseholder' and 'Wharf Phase 3 Condo Owners'. Most mail to one Atlanta address. In all, 291 lots carry 'Wharf' entities, assessed at $1.58B; the largest is 677 Water St SW, an office building ($242.1M). REBusinessOnline (2014) calls it 'a public-private partnership between the District of Columbia and Hoffman-Madison Waterfront LLC', led by PN Hoffman & Associates and Madison Marquette. The roll records no sale price. The ground-lease terms were not read. |

| Capital One Arena 601 F Street NW (Square 455, lot 47) 217,957 sq ft lot (roll) |
Civic | District of Columbia The roll names the District of Columbia as owner, with land at $232.7M and improvements at $295.5M, for a current assessment of $524.2M. The deed date is 1 Apr 1999, and no sale price is recorded. Bisnow (21 Oct 2024) reported legislation letting the District 'purchase Capital One Arena in Chinatown from Monumental Sports & Entertainment, then lease it back to the sports group through at least 2050', with $87.5M 'allocated to purchase the arena' inside a $515M deal, and the arena would be exempt from property and leasehold taxes. The roll does not record that price, so none is given here, and Monumental's lease does not appear as a lot. |

| Nationals Park 1500 South Capitol Street SE (Square 705, lot 804) 847,636 sq ft lot (19.5 acres) |
Civic | District of Columbia The roll names the District of Columbia as owner, with land at $630.6M and improvements at $425.5M, for a current assessment of $1.06B and no sale on record. That makes it the second most valuable District-owned lot after the convention center. Events DC, 'the official convention and sports authority for Washington, DC', lists the ballpark as one of its venues (opened 2008, 41,418 seats). The roll does not name Events DC, and the Washington Nationals' tenancy is not recorded as a lot. The District built the ballpark, so there is no purchase price. |

| Walter E. Washington Convention Center 801 Allen Y. Lew Place NW (roll: 801 Mount Vernon Pl NW; Square 402, lot 830) 700k+ sq ft exhibit space (Events DC) |
Civic | District of Columbia The roll names the District of Columbia as owner, with improvements at $1.29B and land at $102.9M, for a current assessment of $1.39B. It is the District's most valuable lot. Events DC, the District's convention and sports authority, lists the centre (opened 2003) as its venue and gives the address as 801 Allen Y. Lew Place, after Mount Vernon Place was renamed. On the roll, Events DC's statutory names ('Washington Convention Center Authority' and 'Washington Convention and Sports Authority') hold only 13 small lots worth $16.4M. |

| Union Station 50 Massachusetts Avenue NE (Square 720, lot 171) 389,292 sq ft lot (roll) |
Mixed use | United States of America (Department of Transportation); commercial leasehold taken by Amtrak Federal fee; Amtrak took the leasehold that ran to 2084 The roll names the United States of America as owner, care of the Department of Transportation, with a current assessment of $545.9M. A separate possessory-interest lot still lists Union Station Investco LLC ($74.3M), and Washington Terminal Company holds the adjoining lot 0717-0815 ($59.0M). Haynes Boone (11 Mar 2025) says Rexmark Holdings obtained '$505 million settlement from Amtrak for its acquisition of the leasehold interest', ending condemnation proceedings Amtrak began in April 2022. The extract has not caught up with that change. |

Mixed use | District of Columbia (land); CCDC Office LLC, CCDC Residential Rental LLC, CCDC Retail LLC and CCDC Hotel LLC (improvements) Roll splits 'DISTRICT OF COLUMBIA (LAND ONLY)' from the CCDC entities' '(IMPS ONLY)' The roll splits title by lot, with 'District of Columbia (land only)' and 'CCDC Office LLC (imps only)' at $314.6M. It also lists CCDC Residential Rental LLC at 825 10th St NW ($185.3M), CCDC Hotel LLC at 950 New York Ave NW ($150.4M) and CCDC Retail LLC ($34.2M). In all, 78 lots pair the District with a CCDC entity, assessed at $972.7M. REBusinessOnline (2011): developed by Hines and Archstone, with 'Qatari Real Estate Investment Co.' as principal investor, and 'according to local reports' the District leases the 10-acre site 'for $500,000 annually for a 99-year term'. No document opened here says who holds the CCDC entities today. |

Mixed use | 2600 Virginia Avenue 1 LLC and 2600 Virginia Avenue 2 LLC (office); Watergate Hotel LLC (hotel); Watergate 600 NHA LLC (600 New Hampshire Ave) Roll: the 2600 Virginia Ave office lot (27,996 sq ft) is held by 2600 Virginia Avenue 2 LLC and 2600 Virginia Avenue 1 LLC, mailing to Southfield, Michigan. It sold 30 Sep 2019 for $101.2M and is now assessed at $48.0M, less than half that price. Watergate Hotel LLC holds 2650 Virginia Ave ($50.7M) and its condominium units. Watergate 600 NHA LLC bought 600 New Hampshire Ave NW on 9 Mar 2026 for $52.5M, against an assessment of $115.8M. The residential co-operatives and condominiums are held by their residents and are not named. No document opened here names who stands behind these LLCs. |

It mails to 550 Madison Ave, New York. Bisnow (10 Jun 2026): 'BDT & MSD Partners has purchased 1100 Pennsylvania Ave. NW … the General Services Administration announced'. BDT & MSD had taken the Waldorf Astoria leasehold at an August 2024 foreclosure auction, as lender, after CGI Merchant Group bought the lease in 2022. GSA kept public access to the clock tower by covenant. The building passed from federal to private title in 2026. |

Land | United States of America (administrative jurisdiction transferred to the District of Columbia) Federal title; District jurisdiction for not less than 99 years The roll names the United States of America as owner, with tax bills mailed to 1350 Pennsylvania Ave NW. The current assessment is $137.3M, and the proposed land value is $599.9M. Public Law 118-274 (6 Jan 2025) directs the Interior Secretary to 'transfer administrative jurisdiction over the Robert F. Kennedy Memorial Stadium Campus to the District of Columbia'. The transfer runs 'for a term of not less than 99 years' for uses 'including residential and commercial development' and a stadium, but no federal funds may be used for the stadium. It says the transfer 'does not change the status' of ownership. Title stays federal, and it was not a sale. |

It had bought it for $61.75M at the end of 2017, so the new price was 'less than a third of its 2017 sale price'. The roll's owner is Melrose Washington Holdings LLC, with a current assessment of $30.1M. The same roll shows other downtown offices selling far below assessment: 1201 Maryland Ave SW for $57.6M (Jul 2024, assessed $145.1M), 1325 G St NW for $28.7M (Oct 2025, assessed $92.6M), and 1030 15th St NW for $46.9M (Dec 2024, assessed $100.6M). |

The core land
The most valuable ground in the city, and what the public record says about it.
Washington's most valuable ground is federal and civic: the Capitol, the Mall's museums, the convention centre and the ballpark. Downtown's private office land is assessed at around $1,700 per sq ft. Figures are current assessed values (land plus improvements) from the OTR Integrated Tax System Public Extract read 14 Oct 2026 (latest extract date 13 Oct 2026), summed by this research.
All property in the District$380.2 billion
221,667 tax lots, including possessory-interest and condominium lots. The 188,286 residential lots total $185.0B. ITSPE, Oct 2026.
Highest-valued lot$2.12B
US Capitol grounds (Square 636, lot 815; 59.1 acres), United States of America. The District's own highest is the Walter E. Washington Convention Center, $1.39B. ITSPE, Oct 2026.
Highest-valued private lot$614.5M
1100 15th St NW, 1100 15th Street LLC. Next is Constitution Center, 400 7th St SW, CC Owner LLC ($593.8M), which sold 13 Dec 2012 for $734.0M, the roll's recorded price. ITSPE, Oct 2026.
Downtown land benchmarkabout $1,680 per sq ft
Median assessed land value per sq ft of lot across 328 large office lots (over 10,000 sq ft) in the 'Central' assessment neighbourhood; the highest is $3,366. Foggy Bottom's median is $847. ITSPE, Oct 2026.
Deed recordation and transfer taxes1.45% + 1.45% (1.1% each under $400,000 residential)
Recordation tax and transfer tax are each 1.1% of consideration for residential transfers under $400,000 and 1.45% 'on the entire amount' otherwise (OTR ROD FAQs, Oct 2026). Class 2 commercial property tax runs $1.65-$1.89 per $100 of value.

Who owns the town
At this scale the significant owner is rarely a trust or a fund: it is one or two local holding companies, a family in its second or third generation, and often the land around the town rather than the buildings in it.
Washington is a federal city, and the roll shows it. Lots titled to the United States cover about 13,000 of the 33,000 acres of surveyed lot area, about two-fifths, and are assessed at $64.4B of the city's $380.2B. The District of Columbia is the second landholder, followed by the universities. Most federal rows give no agency, so the split between GSA, the National Park Service, the Architect of the Capitol and Defense cannot be measured from the roll. Figures are current assessments from the ITSPE extract read 14 Oct 2026, grouped across every spelling of each name. Acreage is the surveyor's lot area, excluding possessory-interest and condominium lots.
| Name | Type | ITSPE roll, Oct 2026 |
|---|---|---|
| United States of America (GSA, National Park Service, Architect of the Capitol, Defense and others) The roll's most valuable lot is the US Capitol grounds ($2.12B, 59.1 acres). Next come 1000 Constitution Ave NW ($1.26B) and 1100 Ohio Dr SW ($1.24B, 373 acres). Only a minority of rows carry an agency in the care-of field: GSA on 53 lots ($1.67B), the National Park Service on 17 (877 acres), the Navy, the Air Force (357 acres) and the State Department. Another 29 lots ($968.1M), including the Georgia Ave and Judiciary Square sites, are titled jointly to 'United States of America & District of Columbia'. |
Government | 2,996 lots, $64.43B, about 13,035 acresA |
| District of Columbia Includes the Walter E. Washington Convention Center ($1.39B), Nationals Park ($1.06B), the Blue Plains site at 5000 Overlook Ave SW ($573.3M) and Capital One Arena ($524.2M). It also holds the fee under the Wharf and CityCenterDC ground leases, where the roll names the leaseholders alongside. |
Government | 2,667 lots, $20.26B, about 2,848 acresA |
| The George Washington University The largest private landholder by value. Besides the Foggy Bottom campus (817 23rd St NW, $338.4M), the roll names GWU as owner of the 2100 Pennsylvania Ave ($262.6M) and 2200 Pennsylvania Ave ($243.0M) office lots. BXP's 10-K lists both buildings in its own portfolio, so the University owns the ground beneath a REIT's towers. In 2024-2026 it also bought 2001 Pennsylvania Ave NW ($35.0M) and 2300 M St NW ($51.4M) (roll). |
Institution | 120 lots, $4.52B, 65.7 acresA |
| Howard University The roll titles most of it 'Howard University (Land Only)', including the hospital site at 520 W St NW ($521.6M) and the 2900 Van Ness St NW campus ($186.5M). |
Institution | 137 lots, $2.68B, 176.1 acresA |
| District of Columbia Housing Authority Public housing estates such as 461 H St NW ($81.9M), 7 M St NE ($77.8M) and 1200 Delaware Ave SW ($69.7M). The roll mails its bills to 1133 N Capitol St NE. |
Government | 978 lots, $1.92B, 310.4 acresA |
| Georgetown University (all named entities) The main campus at 3800 Reservoir Rd NW ($420.3M, 77 acres) and the Law Center at 550 1st St NW ($347.2M), under 11 spellings including 'President & Directors of Georgetown University' and 'Georgetown College Law Center'. |
Institution | 140 lots, $1.54B, 114.6 acresA |
| Washington Metropolitan Area Transit Authority (WMATA) Includes 600 5th St NW at 600 5th St NW ($314.8M), the rail yard at 2250 26th St NE (17.6 acres) and Metro Center at 13th and F, held jointly as '13th & F Associates LP & WMATA' ($323.0M). |
Government | 404 lots, $1.46B, 210.0 acresA |
| The Catholic University of America The Brookland campus at 3502 John McCormack Rd NE ($431.0M, 95 acres), plus vacant land on Harewood Rd NE (41 acres). |
Institution | 315 lots, $701.8M, 175.7 acresA |
| Potomac Electric Power Company and PHI Service Company (Exelon utilities) Substations and plant sites, including 3400 Benning Rd NE (66.8 acres) and 1930 1st St SW. PHI Service Company bought its headquarters at 701 9th St NW on 15 Apr 2025 for $175,000,000 (roll), the largest office sale in the city since 2024. |
Public company | 76 lots, $760.3M, 182.3 acresA |
| National Railroad Passenger Corporation (Amtrak) Rail land near Union Station and along New York Ave NE. Union Station itself is titled to the United States (Department of Transportation), and Amtrak's 2025 leasehold settlement is under the Union Station entry. |
Government | 15 lots, $76.7M, 22.1 acresA |
| Events DC (Washington Convention and Sports Authority) Under its statutory names it holds 13 lots: small parcels near the convention centre and a 3.2-acre recreation lot at 1100 Oak Dr SE ($10.7M). The convention centre and Nationals Park are titled to the District of Columbia, not to Events DC. |
Government | 13 lots, $16.4MA |

Who builds the houses
New-home building in this market: the volume, and the firms behind it. Ownership of a builder matters as much as its volume — a private-equity platform and a family firm behave differently.
Washington builds apartments, not houses. Census permit files count 4,740 new units in 2021, 7,705 in 2022, 3,020 in 2023, 1,737 in 2024 and 1,591 in 2025. In 2025 that was 181 single-family units and 1,372 in buildings of five or more, so more than eight in ten new homes are in apartment blocks. Tract homebuilders barely register. The table counts what the roll shows in each builder's own name. The large rental developers hold each building in a separate LLC, and the roll rarely names who stands behind it. The roll names private individuals as owners of most homes, and none is reproduced.
| Name | Type | Holdings in own name, ITSPE roll, Oct 2026 |
|---|---|---|
| NVR, Inc. (Ryan Homes) Under five spellings of 'NVR, Inc.', mostly 'Vacant-Permit' lots on Ridgeline Lane and Summit Way SE bought in 2025-2026 at about $255,000-$265,000 each, plus a 37,707 sq ft Town Center Dr SE site bought 6 Jul 2026 for $2,955,000. These are townhouse lots in Ward 8. |
Public company | 37 lotsA |
| Toll Brothers, Inc. ('Toll DC' entities, apartment living) Toll DC II LP holds 200 K St NE in NoMa ($196.3M, land bought 12 Apr 2013 for $30.15M), and Toll DC Phase III Owner LLC holds 1010 Half St SE ($132.9M). Both mail to 1140 Virginia Drive, which EDGAR gives as Toll Brothers' business address. Toll DC LP's 1011 1st St SE ($106.9M) changed its record on 17 Jun 2026 and now mails to a Newark, NJ address. No document opened here says who holds it now. |
Public company | 3 apartment lots, $436.1MB |
| District of Columbia Housing Authority The largest holder of rental housing on the roll. Its estates are the sites of the District's mixed-income redevelopments, and the private partners on each redevelopment were not established here. |
Government | 978 lots, $1.92BA |

Commercial landlords
The commercial side, counted separately from housing: who holds the office, retail and industrial floor area.
Downtown Washington's office market is owned largely through single-asset LLCs, and the roll names only the LLC. Since 2024 the roll has recorded a run of sales far below assessment, and the buyers include universities, foreign governments and the local utility as well as investors. Only landlords that file accounts or carry self-identifying entity names are counted here. Wharf and CityCenterDC leaseholds are under the marquee entries.
| Name | Type | Washington, DC holding |
|---|---|---|
| BXP, Inc. (formerly Boston Properties) BXP's 2025 10-K property table lists 901 New York Ave (524,021 sq ft), 2100 Pennsylvania Ave (475,849), 2200 Pennsylvania Ave (460,039), 1330 Connecticut Ave (253,375), 500 North Capitol St (230,900 sq ft, 30% interest), Sumner Square (208,797) and Capital Gallery (176,909). In 2025 it bought vacant 2100 M St for about $55.9M including costs, and sold its stake in Market Square North. On the roll, BXP- and BP/-named entities mail to 2200 Pennsylvania Ave NW. The 2100 and 2200 Pennsylvania lots are titled to George Washington University. |
REIT | 7 in-service office properties, 2,329,890 sq ft, plus 725 12th St (320,000 sq ft) in redevelopmentA |
| Douglas Development-linked entities (shared name prefix and address) 127 LLCs whose names share one prefix, mostly mailed to 655 New York Ave NW Suite 830 or 701 8th St NW Suite 620. They include 1155 F St NW ($189.7M), the former Woodward & Lothrop store at 1025 F St NW ($168.5M), 950 F St NW ($148.5M) and 99 M St SE (bought 1 Jun 2026 for $93.25M). This is the largest private portfolio on the roll by count. The roll does not name the parent company, and no filing opened here does, so the grouping rests on the shared name and addresses. |
Private company | 395 lots, $2.26B, 114 acresB |
| Hoffman-Madison Waterfront ('Wharf' leasehold entities) About 30 'Wharf … REIT Leaseholder' and 'Wharf … Condo Owner' LLCs on District-owned land at the Southwest Waterfront (see marquee). |
Developer | 291 lots, $1.58BB |
| CityCenterDC entities (CCDC Office, Residential Rental, Retail and Hotel LLCs) Improvements on District-owned land under a 99-year ground lease, according to a 2011 report. Hines developed the project, and a Qatari Diar fund was the principal investor (see marquee). |
Private company | 167 lots, $1.21BB |
| Smith Property Holdings (care of Equity Residential) Apartment buildings such as 3003 Van Ness St NW ($163.3M), Alban Towers ($86.1M) and 2950 Van Ness St NW. One lot's care-of line reads 'In care of Equity Residential', and others mail to 4040 Wilson Blvd, Arlington. Only that care-of line ties the entities to Equity Residential. No 10-K was opened here. |
REIT | 36 lots, $518.1M, 15.5 acresB |

Looked for and not found
Claims this page would have made if a source could be opened. They are left out rather than guessed.
- Whether the District's purchase of Capital One Arena from Monumental Sports & Entertainment ($87.5M in the 2024 legislation) has closed, and on what date. The roll names the District as owner but records no sale.
- The Wharf and CityCenterDC ground-lease terms, and who stands behind the 'Wharf … REIT Leaseholder' and 'CCDC' entities today. A REIT structure is implied by the entity names, but no filing opened here names the investors.
- Who stands behind 2600 Virginia Avenue 1 and 2 LLC, Watergate Hotel LLC and Watergate 600 NHA LLC.
- That the entities sharing one name prefix are Douglas Development's. The grouping rests on the shared name and mailing addresses, not on a document.
- Union Station: the roll still lists Union Station Investco LLC on the possessory-interest lot after Amtrak's 2025 settlement, and the post-settlement owner of the leasehold was not read from a deed.
- The split of federal land between GSA, the National Park Service, the Architect of the Capitol and the Department of Defense. Most federal rows on the roll carry no agency.
- 1030 15th Street NW's earlier price. CommercialSearch's article (Cloudflare-blocked) gives $552.07 per sq ft for a sale in an unstated year, so no prior price or discount is claimed.
- No deed image was read, because the Recorder of Deeds portal requires registration and robots.txt disallows it. Prices here are the roll's 'most recent sale price' or a cited document's.
- The roll names private individuals as owners of most homes and condominium units, and a few office lots. None is reproduced.
