Royal Pools by Adams builds custom inground pools and spas for homeowners throughout Cupertino. The city’s 1960s-to-1980s housing stock means a significant share of existing pools are now 40 to 50 years old, prime candidates for renovation or full replacement. For homeowners building new, Cupertino’s hillside overlay zones in Monta Vista, Linda Vista, and Stevens Creek add a permitting layer that requires a contractor with direct experience in the City’s review process. We are Diamond Certified, CSLB licensed (License #278052, C-53 Swimming Pool), and have served South Bay homeowners since 1953.
We offer Cupertino homeowners a full range of pool and outdoor water feature services:
From the first excavation to the final finishing coat, our licensed crews deliver complete inground pool installations backed by over 70 years of Bay Area craftsmanship and a Diamond Certified quality guarantee.
Our design team collaborates with you through every detail, translating your vision into a fully engineered blueprint for a one-of-a-kind residential pool that complements your landscape, architecture, and lifestyle.
When your pool’s interior shows cracks, staining, or rough texture, our Diamond-Certified replastering team restores both structural integrity and visual appeal with long-lasting finishes that protect your investment for decades.
We engineer commercial aquatic facilities for HOAs, resorts, schools, and municipalities, built to meet ADA compliance requirements, California health code standards, and the durability demands of high-traffic aquatic environments.
Our smart automation installations give you fingertip control over temperature, LED lighting, jets, filtration, and water chemistry from any smartphone or tablet, so your pool is always ready when you are.
We retrofit and upgrade pumps, heaters, variable-speed filters, and sanitization systems to extend your pool’s service life, reduce monthly energy costs, and bring older installations into compliance with California efficiency regulations.
Cupertino homeowners in the Monta Vista and Rancho Rinconada neighborhoods sit on some of the larger residential lots in the city, giving them the space for full-sized inground pools and integrated outdoor living areas. In the hillside overlay zones, pool construction requires a contractor who knows how to navigate the additional permitting steps and engineering requirements that apply there.
Our Diamond Certified rating is a third-party verified credential based on customer satisfaction surveys. Our C-53 Swimming Pool Contractor license from the California State License Board is the required license category for residential pool construction in California. We manage permitting, inspections, and startup, and we offer pool financing for qualifying Cupertino homeowners.
Pool construction in Cupertino requires a building permit from the Cupertino Building Division, located at 10300 Torre Ave. (408-777-3228). You will need engineered construction drawings, a site plan showing pool placement relative to property lines and structures, and pool barrier documentation meeting California Health and Safety Code Section 116049 requirements (four-sided isolation fencing, 60-inch minimum exterior height, self-latching gate). We prepare and submit all permit documentation on your behalf.
If your property is in one of Cupertino’s hillside overlay zones, specifically Monta Vista, Linda Vista, or Stevens Creek, additional planning review may apply to pool construction. Properties in these zones with significant slopes may require a hillside exception or additional geotechnical documentation. We identify whether your parcel falls within a hillside overlay zone during the initial site visit and advise on the expected permit pathway before design work begins.
All inground pool construction in Cupertino requires a building permit from the Cupertino Building Division at 10300 Torre Ave. (408-777-3228). The permit process includes submission of engineered construction drawings, plan check review, and inspections at multiple construction stages (excavation, steel, plumbing, shell, and final). Properties in hillside overlay zones may require additional planning review or a separate hillside development approval before the building permit is issued. We handle the complete permit application on your behalf and track the review timeline as part of the project schedule.
It may. Monta Vista, along with Linda Vista and Stevens Creek, is one of Cupertino’s identified hillside overlay zones. Properties within these zones that have slopes meeting specific thresholds, or that are located in areas the city has designated for additional hillside review, may require a planning application or hillside exception in addition to the standard building permit. The specific requirements depend on your parcel’s slope, proximity to ridgelines, and any existing conditions documented in the city’s records. We determine whether your parcel triggers hillside overlay requirements during the initial site visit using current city zoning maps and parcel data, so you know the full permit scope before design work begins.
California’s Title 20 Appliance Efficiency Regulations, effective January 1, 2025, require that all new pool pumps with a motor of one horsepower or greater be variable-speed models meeting the applicable efficiency certification. This is a statewide code requirement that applies to all new pool construction in Cupertino and to any renovation project that includes pump replacement. Variable-speed pumps are not optional; they are the required standard. Cupertino is served by Silicon Valley Clean Energy (SVCE) for electricity, and SVCE does not currently offer a rebate for pool pumps. The efficiency benefit of variable-speed pumps, however, results in meaningful energy savings relative to older single-speed models regardless of rebate availability.
Cupertino’s 1960s-to-1980s housing stock produced a large number of pools that are now 40 to 50 years old. The most common issues we find in pools of this age include: single-drain configurations that do not meet Virginia Graeme Baker Act (VGBA) anti-entrapment requirements (mandatory compliance for any project touching the drain system), deteriorated plaster that has thinned or delaminated from the shell surface, galvanized steel fittings and returns that have corroded and are failing, and aging single-speed pumps that do not meet current Title 20 standards. A shell inspection before deciding between renovation and full replacement will clarify what the project actually involves and which path makes more economic sense for the specific pool.
Cupertino is served by San Jose Water (SJW), which blends water from multiple sources. Depending on the source blend in effect at a given time, total hardness in the SJW supply can range from approximately 119 mg/L to as high as 364 mg/L. This range spans from moderately hard to Very Hard. Harder water periods accelerate calcium scale buildup on pool plaster surfaces, tile grout, and equipment. We account for Cupertino’s water profile when recommending plaster finishes: quartz aggregate and specialty plaster surfaces resist calcium scaling better than standard white plaster. We also implement a chemical startup protocol that adjusts calcium hardness and pH in the fill water before the pool opens, which establishes a healthier baseline from the first day.
