Luxury Remodeling in Monterey Park
Design-build pools, outdoor living and ADUs planned around Monterey Park's hillside lots and expansive soils.
Building in Monterey Park
Hillside backyards, pools and ADUs for Monterey Park homes.
The Repetto Hills give Monterey Park its shape, forming part of the San Gabriel Valley's southern boundary and dividing the city into distinct neighborhoods, some of them looking out over downtown Los Angeles and the valley. In the 1920s Peter N. Snyder planned Midwick View Estates here as a garden community meant to rival Bel-Air and Beverly Hills, but the Depression ended the venture, leaving the observation terrace and the stepped-pool fountain now called Heritage Falls Park, or the Cascades. Many of the city's single-family homes date from the 1950s and 1960s, so a new pool or ADU is often planned around a house and yard that have been in place for decades. The ground matters as much as the house: soils that swell when wet are present in many parts of the city, and on the hillsides drainage and slope stability need answers before a pool or an addition is drawn.
Single-family homes account for about three-quarters of the city's residences, and they range from level ground in the northeast to hillside streets, some with panoramic views of downtown Los Angeles and the San Gabriel Valley. The R-1 standards set a 25-foot front setback, reduced to 10 feet for a house or garage on a hillside lot, cap homes at two stories or 30 feet, and step the floor area ratio down from 0.50 on lots under 6,000 square feet to 0.40 on lots of 6,000 to 10,000 and 0.35 on lots over 10,000.
One team designs, permits and builds every project, and our own crews self-perform the work, so the people who plan your Monterey Park project are the people on site building it.

What building in Monterey Park involves
Permits in Monterey Park
City of Monterey Park Community Development Department, Building and Safety Division
The Building and Safety Division at 320 West Newmark Avenue requires a building permit for work such as a patio, a retaining wall or a swimming pool, and the Public Works Department issues a separate grading permit once the cut and fill of a grade adjustment exceeds 50 cubic yards. The city's residential guidelines for MPMC 21.08.080 allow a pool in a side or rear yard with at least five feet to any property line or structure, never in a required front yard, and pool lighting must be aimed away from abutting properties. Pool pumps, filters and heaters belong in a rear or interior side yard, at least five feet from a side or rear line shared with another residentially zoned lot, and must be screened from the street and neighboring lots; any other location needs City Planner approval. ADU plans are emailed to the Planning Division for preliminary review before they are submitted through the Building Division portal, and the city runs a designer-owned pre-approved ADU plan program.
Permit details checked September 2026 against State of California. Rules change, so we confirm them again for your parcel.
What we plan for here
- Expansive-soil footing and slab design
- Hillside drainage and retaining walls
- Public Works grading permits over 50 cubic yards
- Screened pool equipment placement
- Planning pre-review for ADUs
Expansive soils, which swell when wet, are present in many parts of the city, with claystone and alluvium most common and siltstone next, and new footings and slabs must follow the Building and Safety Division's expansive-soil guideline unless a soils investigation report says otherwise.
Combined with the hilly terrain, those soils contribute to slope creep, settlement and landslides. The General Plan Safety Element records slope failures during significant rainstorms and earthquakes, including steep slopes along Abajo Drive that failed in the 1987 Whittier earthquake, and notes that these episodes led the city to adopt progressively stricter grading and slope stabilization rules.
No active fault has been identified at the ground surface within city limits and no Alquist-Priolo zone is designated, but the city overlies the Puente Hills, Elysian Park and East Los Angeles blind thrust faults, and the Safety Element notes that ridge-top locations may see elevated ground shaking.
The Safety Element rates brush fire as a minimal threat, most likely on the steep hillsides beside Monterey Pass Road, near Garvey Reservoir and at a few spots where backyards slope into undeveloped canyons.
