Backyard Remodeling in Pomona

Pulling permits for a backyard remodel in Pomona runs through the City of Pomona Building Safety Division, which is part of the Development Services Department. Pools and spas always require a permit, and so do patio covers, California rooms, new gas lines serving a grill, fire pit or pool heater, new electrical circuits, and retaining walls or grading past the local thresholds. One thing that makes Pomona straightforward compared to some cities is that no unusual local overlay applies, so the building code and the age of the house are the governing factors. That last point matters because Pomona’s housing stock spans a wide range, from older wood-framed homes near downtown that were built under earlier code cycles to the two-story tract homes on the hillside subdivisions in Phillips Ranch that went up under more recent standards. The rules that apply to your project depend heavily on what era your house was built in and what trades the scope touches. Setbacks for pools, equipment pads, covers and fire features vary from one city to another, so we work those out during layout rather than waiting until plan check. Where an HOA is involved, its architectural committee typically reviews pools, covers, walls and visible landscape changes before the city does, and we plan the schedule around that review.

Drainage is one of the decisions that determines how long a finished yard actually holds up. Every new patio, pool deck and solid cover roof converts ground that used to absorb rain into hard surface that sheds it. We set grades in the drawings so the ground falls away from the house on all sides, connect downspouts into drain lines, and add area or channel drains where hardscape meets the foundation. Permeable pavers, gravel or planted areas go in where they fit the layout. Water is directed to an outlet the city allows, which is typically the street, never over a fence onto a neighboring property. Retaining walls get drainage material behind them during construction because a wall that traps water behind it does not stay standing. Many building departments require a permit for any retaining wall taller than four feet measured from the bottom of the footing, or for a wall that holds back a slope, driveway or structure.

Landscape area and water use have their own set of requirements. California’s Model Water Efficient Landscape Ordinance applies to new and rehabilitated landscapes, and every city and county adopts it or a stricter local version. Smaller backyard projects often fall below the thresholds, but larger permitted landscapes can require a water budget and an irrigation plan as part of the submittal package. If replacing a lawn and a water agency turf replacement rebate is available, the approval has to be obtained before any grass is removed, the replacement area has to remain permeable, and synthetic turf does not qualify under most programs. These details are worth sorting out before a shovel goes in the ground.

If the property falls within a CAL FIRE mapped Fire Hazard Severity Zone, the planting and material choices near the house follow a different set of priorities. The first five feet around the structure, known as Zone 0, carry the most weight, so we use hardscape or gravel in that zone rather than bark mulch, keep fire features clear of structures, overhangs and trees, and design attached covers with ignition resistance in mind. Pool and spa work carries a separate state requirement: when a permit is issued for a new or remodeled pool or spa at a single-family residence, state law requires that at least two of seven listed drowning-prevention features be in place before final inspection. We account for all of these layers during the design phase so nothing surfaces as a surprise at the end of the job.
