Website design for a San Dimas business: what the place tells you

16.3% of San Dimas commuters spend an hour or more getting to work, and the average trip takes 31.6 minutes. People who leave early and come home late do their errands online, and the website is open when they are home. If you work outside office hours, put that in the first lines; it decides the choice for many residents. None of that needs a big website. It takes an honest one, with the details right.

Ever since 1960, San Dimas has built up more than half a century of local history. Customers in an older city usually ask around first, and the website is where that recommendation gets checked. New in town? Then the website has to do what word of mouth does for the older names: explain exactly what you do and for whom.

With Interstate 10 crossing the city limits, San Dimas sees a steady flow of travelers. Highway traffic brings freight: trucking, repair, towing and parts suppliers serve people who will never live in San Dimas. One screen with services, hours and location is all a driver has time for.

Reading the San Dimas customer

Homeownership is high in San Dimas: 72.4% of households own, against 55.9% in California. Homeowners hire contractors, landscapers, cleaners and insurance agents, and many look them up online first. 8.2% of San Dimas residents speak Chinese at home. That is one more reason to keep the website’s language plain and direct.

About 19.7% of the city speaks Spanish at home. If your team speaks Spanish, one line on the contact page saying so answers a question many visitors have.

ZIP code 91773, mostly within San Dimas, had 1,274 employer establishments in the 2023 count. Some of the businesses behind that number:

  • Pest control companies: 7. Their website should show a page for each pest you treat, the areas you cover and a form for inspection requests.

  • Dental offices: 24. Their website should show the treatments you offer, a map to the office and a contact form, written in plain words for nervous patients.
  • Beauty salons: 15. Their website should show a page per service, your hours and location and a contact button for appointment requests.

Los Angeles County has about eight times the national share of performing arts and spectator sports businesses: 19,156 of them in the 2023 count. In that line of work, audiences look for schedules and tickets, so the website should show the schedule, venue information and how to buy tickets.

Paperwork and rules for California businesses online

Before your website goes live, it helps to have the basics of the business in order.

  • The California Consumer Privacy Act, as amended by the California Privacy Rights Act (CCPA/CPRA) rarely reaches a local business: 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.)
  • Check with both Los Angeles County and the City of San Dimas about local business tax receipts before opening. 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)
  • If you send marketing email from your new business address, the CAN-SPAM rules (16 CFR Part 316) apply, including an easy way for people to opt out. 16 CFR Part 316

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