Building activity

WHAT’S BEING
built.

New buildings mean new properties to lease and new businesses to open. Census Building Permits Survey, August 2026.

Builders in the Washington, DC metro were authorized to build 17,340 new housing units from January through August 2026, 29% more than the 13,439 in the same months of 2025.

59% of those units are in buildings with five or more homes, against 32% nationally.

That is an apartment-heavy pipeline. Each new community needs a leasing website, usually before construction finishes, and the developer often needs a project site for investors and the city as well.

Jan–Aug 202513,439
Jan–Aug 202617,340
  • Single-family 6,997
  • Two to four units 156
  • Five or more 10,187

What this means for your site

BUILT FOR
Washington, DC.

What we would plan into a Washington, DC website, based on the numbers above.

Talk through your site
  1. 01

    A site for each property

    Commercial building owners and lessors have 695 staffed offices in the metro, 1.06 times the national share of local businesses. A leasing website for each center or building, with a site plan and available suites, gives tenants and their brokers a direct path to the owner.

  2. 02

    Pages written for owners

    Washington, DC has 1.20 times the national share of property management companies, so owners have several firms to compare. A management website needs its services, reporting, and a request for a management proposal where an owner can find them.

  3. 03

    Launch before the building opens

    59% of new homes permitted this year are in buildings of five or more units. Pre-leasing websites need to be live months before the first move-in.

  4. 04

    Washington, DC license details

    Brokerage websites in Washington, DC carry specific disclosure requirements (17 DCMR §2615; 17 DCMR §2699). We build them into the footer and listing templates, so every page that advertises a property has them.

  5. 05

    Accessible by default

    Every site we build follows WCAG 2.2 AA practice: readable contrast, keyboard navigation, labeled forms, and text alternatives for images. Federal ADA website lawsuits run into the thousands each year, most of them filed in New York, Florida, and Illinois.

Washington, DC rules

WHAT THE LAW
asks of your site.

District rules that change what goes on a business or real estate website in Washington, DC, checked against official sources as of October 9, 2026. This is general information, not legal advice; your counsel owns the final wording.

Worth knowing A DC web page that a firm or licensee owns or controls must carry an on-line disclosure, or a link to one, showing the firm's licensed name, the city and state of its main office, and the jurisdiction where it is licensed, under 17 DCMR § 2615.

Privacy

Privacy law status in Washington, DC

Source

The District of Columbia has not enacted a comprehensive consumer data privacy law as of October 9, 2026. This reflects published state privacy-law trackers. Part of the metro is in Virginia, where the Virginia Consumer Data Protection Act applies to businesses anywhere that meet its thresholds for Virginia residents’ data. Part of the metro is in Maryland, where the Maryland Online Data Privacy Act of 2024 applies to businesses anywhere that meet its thresholds for Maryland residents’ data.

Real estate advertising

What a Washington, DC brokerage site must show

17 DCMR §2615; 17 DCMR §2699 Source

DC advertising must be supervised by the principal or supervising broker and run in the firm's name, with the firm's licensed name displayed clearly and legibly on all advertising. A web page that a firm or licensee owns or controls must carry an on-line disclosure or a link to one, and the regulations define that disclosure to include the firm's licensed name, the city and state of its main office, and the jurisdiction where it is licensed.

What the website needs
  • Under 17 DCMR §2615.3, all advertising must be under the direct supervision of the principal broker or supervising broker and in the name of the firm, and the firm's licensed name must be displayed clearly and legibly on all advertising.
  • Under 17 DCMR §2615.4, online advertising, including email, web pages, message board postings, instant messages and chat, is subject to the same requirements as other advertising.
  • Under the online disclosure provision of 17 DCMR §2615, if a firm or licensee owns a web page or controls its content, the viewable page must include an on-line disclosure or a link to one.
  • Under 17 DCMR §2699, an on-line disclosure is a notice containing the firm's licensed name, the city and state of the firm's main office and the jurisdiction where the firm is licensed, or, for a licensee's advertising, the licensee's name, the affiliated firm's name, the city and state of the licensee's office and the jurisdiction where the licensee is licensed.
  • Under the same provision, email, newsgroup, discussion list and bulletin board messages must include the on-line disclosure at the beginning or end of each message, except correspondence in the ordinary course with people who already have a brokerage relationship with the licensee.

Accessibility

The federal ADA

ADA Title III Source

Title III of the ADA covers businesses open to the public, but the Department of Justice has no regulation that sets a technical standard for private business websites. DOJ's web guidance says businesses have flexibility in how they make their websites accessible and points to WCAG as a helpful existing technical standard. Federal appeals courts have not agreed on when a website is covered, so a website's legal status can depend on where a lawsuit is filed and whether the site is connected to a physical location. Washington, DC has no separate website accessibility statute for private businesses in our research, so WCAG 2.2 AA is the practical target.

Client words

IN THEIR
words.

We own ten homes at Casa De Laguna and were still sending people to a site built in 2013. Noah pulled the photos and details out of the old site, designed a logo from the rooflines and the pond, and put the community, the homes and current availability in one place. It’s the first time the website has looked like the place we actually rent.
