Royal Pools by Adams designs and builds custom inground swimming pools across the 94539 zip code, Fremont’s foothill estate country below Mission Peak. We are a Diamond Certified pool construction company based about 25 minutes south on Camden Avenue in San Jose, and we have been building Bay Area pools since 1969. Our five-step program takes your project from first sketch to first swim.
Start with the naming trap: 94539 contains Mission San Jose, but it is Fremont, and your pool permit comes from the City of Fremont’s Citizen Access portal, not from San Jose. The zip pairs two of Fremont’s five founding districts, Mission San Jose and the residential core of Warm Springs, and it carries the city’s most prestigious housing: about 52,400 residents across 17,400 households, a median home year of 1980, and estate streets that climb from the valley floor into the foothills below 2,517-foot Mission Peak. That climb is where builder selection matters. Foothill lots in Vineyards-Avalon, Kimber Park, and the Weibel hills get our engineering-first treatment: per-lot soils review, retaining and drainage design, and layouts oriented to views that reach across the bay. The valley-floor blocks around Mission Boulevard and the Warm Springs BART station build conventionally, and Fremont’s pool code adds two of seven drowning-prevention features to every new residential pool. The Alameda County Water District fill water is a managed blend whose hardness varies, so startup chemistry begins with a test, not an assumption. Estate lots, real engineering, honest process: that is 94539 done right.

We build across Fremont’s estate zip:
The 1797 mission district and Fremont’s most prestigious neighborhood.
The residential heart of Fremont’s southernmost founding district.
Vineyards-Avalon, Kimber Park, and the Weibel hills, where engineering earns the views.
Our citywide Fremont page.
Fremont, always. The Mission San Jose name refers to the 1797 mission, but the district has been part of the City of Fremont since 1956, so every 94539 pool permit goes through Fremont’s Citizen Access portal and Building and Safety at the Development Services Center, 39550 Liberty St. We manage the whole process.
94539 covers Mission San Jose and the residential core of Warm Springs, including the foothill estate neighborhoods of Vineyards-Avalon, Kimber Park, and the Weibel hills.
Yes, it is the zip’s signature build. Foothill parcels below Mission Peak get per-lot soils review, retaining and drainage engineering, and designs oriented to the views, handled by a team that leads with the engineering instead of discovering it mid-project.
Alameda County Water District, on a typical-year blend of roughly 40 percent State Water Project, 20 percent San Francisco regional supply, and 40 percent local Alameda Creek watershed sources including Niles Cone groundwater. We test and balance the startup chemistry on fill day.
The complete composition: pool, raised spa, outdoor kitchen, fire features, and hardscape designed as one piece around the view. The zip’s larger foothill parcels are built for resort-scale outdoor living.
At least two of seven drowning-prevention features under Fremont’s Swimming Pool and Spa Code, such as isolation fencing with self-latching gates, an ASTM-rated safety cover, or door and water-entry alarms, designed in from the start and documented for inspection.
