Pool & Spa Remodeling in San Dimas

City of San Dimas Community Development Department, Building and Safety Division. Under Municipal Code Chapter 18.12, no building or structure may be built, altered or enlarged until its development plan has been reviewed and approved. Planning Division staff approve pools and spas (with or without retaining walls), ADUs and junior ADUs, and one-story additions designed to match the existing house; new homes, additions of more than one story, and patios, gazebos or ground-level decks that use cantilevers or retaining walls and are visible from a public right-of-way go to the Director of Community Development. The Director can send a staff-level project to a higher level of review when it could be incompatible with, or adversely affect, surrounding property. In the SF-H Single-Family Hillside Zone, a development plan must be approved before any grading or building, and grading or building permit applications there must include site plans, conceptual house elevations and grading plans. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.

Residential lots here fall under zones with very different rules. The SF-A agriculture zone permits horses on lots of 16,000 square feet or more, while in the SF-H hillside zone new subdivisions need at least 25,000 square feet of net lot area where the average slope is under 20 percent and a full acre at 20 percent or steeper, with a 140-foot minimum lot width and lot coverage capped at 35 percent. One local condition that shapes the work: CAL FIRE's Local Responsibility Area map dated March 24, 2025 places much of the Northern Foothills, including the canyon terrain around Horsethief Canyon Park and the San Dimas Canyon Nature Center, in a Very High Fire Hazard Severity Zone, and the southern hills around Via Verde and Bonelli Park carry a mix of Very High, High and Moderate designations, while the level ground around downtown sits largely outside the mapped zones.

All of it, including Via Verde, Northern Foothills and Downtown San Dimas. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.

New pool construction: generally $70,000 to $150,000+ across Southern California. What moves it is size and shape, spa, water and fire features, decking material, automation, and how much access and grading the site needs. We give line-item pricing after seeing the site rather than quoting a number over the phone.

A straightforward replaster with new tile and coping usually runs three to five weeks. A full remodel that includes new decking, equipment and features typically runs eight to twelve weeks. Site access and permit timing are the two things that move that most.

Most new pool builds run about three to five months from permit to first swim. Hillside sites that need engineered retaining or difficult access sit at the longer end of that range.

If the shell and plumbing are sound and you only dislike the surface, replastering with new tile and coping is the efficient choice. If the equipment is aging, the deck is cracked or the shape no longer suits how you use the yard, a full remodel costs less than doing it in two separate phases.

Yes. Our own crews handle the build rather than passing it to a rotating set of subs, which is why the schedule and the finish standard stay consistent.
