City guides / St. Louis
Endcap Design is a web design agency that designs and builds websites for businesses, with the branding and marketing to match, and works remotely with clients outside Southern California. This guide collects the business numbers, building activity, and Missouri rules we would look at before designing a site for a business in St. Louis or elsewhere in the metro, including St. Charles, O'Fallon, St. Peters, and Florissant.
Updated October 2026 with building permits through August 2026, from U.S. Census Bureau data. Sources are listed at the end of this page.

Business mix
Law offices are the most concentrated of these businesses in the St. Louis metro: 54 for every 100,000 residents, and their share of local businesses is 1.02 times the national share. Property management companies are less common here than nationally, at 0.72 times the national share.
The chart compares each sector’s share of St. Louis-area business locations with its share nationally (a location quotient). 1.00× matches the US; higher means the sector is more concentrated here. County Business Patterns 2023.
Building activity
New buildings mean new properties to lease and new businesses to open. Census Building Permits Survey, August 2026.
Builders in the St. Louis metro were authorized to build 4,745 new housing units from January through August 2026, 15% more than the 4,138 in the same months of 2025.
34% of those units are in buildings with five or more homes, against 32% nationally.
The pipeline mixes single-family subdivisions with apartment buildings, so builders, property managers, and the retail landlords who follow new rooftops all have something to launch.
What this means for your site
What we would plan into a St. Louis website, based on the numbers above.
Talk through your siteHousing permits are up 15% over the same months last year. Each new project needs a name, a site plan, and a pre-leasing page, and the retail around it usually follows.
Brokerage websites in Missouri carry specific disclosure requirements (20 CSR 2250-8.070). We build them into the footer and listing templates, so every page that advertises a property has them.
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.
Missouri rules
State rules that change what goes on a business or real estate website in Missouri, checked against official sources as of October 9, 2026. This is general information, not legal advice; your counsel owns the final wording.
Worth knowing Missouri's Act Against Abusive Website or Web Content Access Litigation, RSMo § 537.1250, effective August 28, 2026, lets a business sued over website accessibility ask a court to find the suit abusive, with a presumption in its favor if it begins good-faith fixes within 90 days of written notice.
Privacy
Missouri has not enacted a comprehensive consumer data privacy law as of October 9, 2026. This reflects published state privacy-law trackers. Privacy laws in other states, and federal rules, can still apply when a site collects data from their residents.
Real estate advertising
Every real estate advertisement by a Missouri licensee must contain the broker's regular business name or licensed name and must indicate that the advertiser is a real estate broker and not a private party. If an agent's name or telephone number appears, the advertisement must also include the name and telephone number of the broker or firm that holds the agent's license.
Accessibility
Missouri's law lets a defendant sued over website or web content accessibility, or the attorney general, ask a court to find the lawsuit abusive. A defendant that starts substantial good-faith steps to fix the problem within 90 days of written notice gets a rebuttable presumption that a later claim is abusive, and a court may award fees and costs plus punitive damages or sanctions up to three times the fees. The law applies to litigation pending on August 28, 2026, and expires for most entities if DOJ issues Title III website accessibility standards.
What we design

Client 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.
“Highly recommend. Great work.”

Yes. Endcap is based in Orange County, California, and works remotely with clients outside Southern California by video call, phone, and email. You review the design and the working site online before launch.
We quote each project after a short conversation, once we know the pages, content, and features it needs. The proposal lists the deliverables, schedule, and price, and we agree on it before work begins.
Most websites take two to four weeks once the content is ready. The proposal confirms the schedule.
