Building a fiberglass pool in Lehi

Four feet is tighter than the 5 feet Riverton and Draper use, but the 12-foot rule usually matters more. If your neighbor's house sits close to the shared line, measure 12 feet from their wall, not 4 feet from the line. Whichever puts the pool farther away is the one that counts.

Accessory uses can take up to 30% of the rear yard, which leaves room for a real deck around the water.

The code text we're reading was posted in 2013 and may have been amended since. We treat these numbers as a starting point and check the current text with Lehi before the drawings are final.

The drain rules shape the equipment. A cartridge filter has no backwash to get rid of. With sand or DE, we plan a sewer connection and get Timpanogos's permission as part of the job. And a salt system means every future drain goes to the sewer or a hauler, and salt is hard on soft natural stone, so we'd pair it with dense, sealed coping.

Lehi's drain rule is stricter than most. Riverton allows a pH from 6.5 to 9.0 at the storm drain; Lehi wants 7 to 8 and no detectable chlorine at all, and even then the water department has to authorize it. The route the city prefers is the sewer, with Timpanogos Special Service District's permission.

Salt pools can't use the storm drain at all here. If you want a salt system, plan on draining to the sewer or paying a licensed hauler.

Lehi soils haven't been confirmed lot by lot in anything we've found, and the state survey's hazard maps we rely on are for western Salt Lake Valley. So the soils answer for a Lehi lot comes from testing that lot.

Lehi's 2021 drought plan didn't restrict pools. It recommended careful pool-water habits and kept its fines for sprinkler violations.
