No setup fee: you only pay the $89 monthly fee, after you approve your website.

What makes Brentwood different, and what your website should do about it

The average commute from Brentwood is 40.0 minutes one way, and 29.2% of workers travel an hour or more. Commuters look for businesses that work around their schedule. Make the contact form short and visible on every page, and say when you are available, including evenings or Saturdays if you are. The website is where all of this gets settled, so it pays to get the basics right.

Young children are a big part of Brentwood: 5.2% of residents are under 5, and 26.3% are under 18. That makes Brentwood a strong market for everything that serves a busy family, and every one of those businesses competes for the same parents. Make the contact form short: a few fields is enough to start.

Ever since 1837, Brentwood has accumulated more than a century and a half of businesses, families and habits. History cuts both ways for a small business: the old names are known, and the new ones have to explain themselves faster. Write the year the business started and the names of the people behind it on the About page; a real photo of the owner does more than any slogan.

How Brentwood has changed since 2020

Every annual estimate since 2020 has been higher than the year before: 64,457 in 2020, then 64,857 in 2021, 65,009 in 2022, 65,435 in 2023, 66,177 in 2024, 66,607 in 2025. That compares with −0.5% for California as a whole. Growth like this brings new households that look for local services online before they ask a neighbor.

Weather in Brentwood: plan the website around it

By the 1991-2020 normals of the Mt Diablo Junction weather station (12 miles from Brentwood), August highs average 83°F and December lows average 41°F. Precipitation totals about 26 inches a year, with December the wettest month. The high reaches 90°F or more on about 27 days a year, and the low falls to freezing or below on about 19 days. Mild weather keeps outdoor work going most of the year: patios, yards and outdoor events have a long season. A website that changes with the season help: winter hours, summer specials, storm-season notices, sent by email and included in the monthly fee.

Who your website talks to in Brentwood

Homeownership is high in Brentwood: 82.2% of households own, against 55.9% in California. Brentwood homeowners hire contractors, cleaners, landscapers and insurance agents, and most check them online first.

Government jobs account for 20.8% of employed residents. Stable government payrolls support steady local spending on services.

Half of Brentwood’s homes went up after 2003. New owners have no favorite local business yet.

Reaching customers beyond the Brentwood city limits

Within a short drive of Brentwood you find Oakley (4.4 miles north), Antioch (5.1 miles northwest) and Pittsburg (11 miles northwest). For flights, Buchanan Field Airport (CCR) lies 19 miles away. Brentwood covers 14.9 square miles of land, about 4,481 residents per square mile. There are 22 incorporated cities and towns within 25 miles of Brentwood. Rosie the Riveter World War II Home Front National Historical Park is a short trip away: within 35 miles. A service area page that lists the towns you cover, from Brentwood to Clayton and Antioch, answers the first question many customers have: do you come to me?

Who you compete with in Brentwood

Brentwood shares ZIP code 94513 with the surrounding area, where 1,414 employer businesses were counted in 2023. Among them:

  • Nail salons, 24 in the count. What works online: a price list, the technicians and a contact form.
  • Auto repair shops, 26 in the count. What works online: the services you do, the makes you work on, hours and a form to describe the problem.
  • Dental offices, 45 in the count. What works online: the team, the treatments in plain words and a form that sends appointment requests to your email.
  • Remodeling contractors, 43 in the count. What works online: project galleries by room, the steps of a remodel and a consultation request form.
  • Real estate offices, 44 in the count. What works online: market areas, how you work with buyers and sellers and a contact form.

Contra Costa County as a whole had 25,932 employer establishments in 2023 and another 102,001 nonemployer businesses, the one-person shops and independent contractors that often have no website at all. Contra Costa County has 1.4 times the national share of schools and training providers: 521 of them in the 2023 count. In that line of work, students and parents compare programs and costs, so the website should show programs, schedules, tuition or fees and how to enroll. Next on the list: nursing and residential care facilities, 430 of them, at 1.5 times the national share. For any of them, a clear website is the difference between being compared and being skipped.

Before you publish: California and federal rules

Some homework before launch:

  • Under the Americans with Disabilities Act, businesses open to the public must make their goods and services accessible to people with disabilities, and the Justice Department’s guidance says that includes their websites. ADA.gov guidance
  • Local business tax receipts in California can come from the county and, inside city or town limits, from the municipality: for you, Contra Costa County and Brentwood. Official source
  • California’s statewide sales and use tax rate is 7.25%, and most areas add district taxes of roughly 0.10% to 2.00% on top of it. California Department of Tax and Fee Administration (CDTFA)
  • The California Consumer Privacy Act, as amended by the California Privacy Rights Act (CCPA/CPRA) exists, but its thresholds are high: For-profit businesses doing business in California that meet any one of three tests: gross annual revenue over $25 million; buying, selling or sharing the personal information of 100,000 or more California residents or households; or deriving 50% or more of annual revenue from selling California residents’ personal information. A typical small business (a local service company with a brochure site or a small store) meets none of them and is outside the CCPA – but CalOPPA still requires a privacy policy (see outras_leis_site). California Civil Code, Title 1.81.5 (Civ. Code 1798.100 et seq.)

Rules change and details vary by business; this is general information, not legal advice.
