About Phillips

Ranch

Phillips Ranch, located between Diamond Bar and Chino Hills, is a hillside and master-planned Pomona neighborhood with curving cul-de-sacs and greenbelt trails. The neighborhood’s character concentrates around the Rio Rancho Rd and Village Loop Rd area, where small plazas, coffee counters, and everyday services meet the steady rhythm of commuter traffic. Stucco homes with tile roofs and tidy front yards line winding streets that follow the terrain. The green spine of Phillips Ranch Park and nearby trail links shapes an outdoors-forward routine. Cal Poly Pomona’s cultural calendar and galleries add a campus-adjacent creative note. The 57 and 71 corridors frame the edges, keeping the setting connected while the interior stays residential.

Welcome to the North Country subdivision in Diamond Bar. Featuring 4 bedrooms and 2.75 bathrooms with 1 large bedroom (no closet, but room to add a closet) and 1 bathroom downstairs.

The unpermitted family room addition is 400 sf and 30 years old. It is well built with photo albums showing the construction- which will allow for ease of permitting in the future.

There is a convenient office area or kitchen extension with a fireplace. Breakfast bar seating faces the kitchen from the family room. The upper floor features 3 bedrooms and 2 remodeled bathrooms. The spacious 10079 sf yard offers wonderful vistas of the snowcapped mountains from the elevated view deck which sits atop a 2-bedroom frame and stucco casita consisting of an additional 445 sf.

The slab and back wall and roof were permitted- however, later on the owner enclosed the building without permits- but in a professional manner. Extra-large gated RV parking and multiple storage sheds. Relax in the newer spa that was added in 2024. The HVAC was upgraded circa 2015. The home has been recently repiped with copper- for many years of carefree living ahead! New skylights mid March 2026. A new rollup 2 car garage door and opener were added in 2022. Walk to Peterson Park which has lighted soccer fields and a baseball diamond. A skateboard park is an additional highlight.
