This single-story San Ramon gem with owned solar sits on a quiet cul-de-sac. A covered porch leads through a keyless door to a bright living room with a granite-framed fireplace for cozy nights, a skylight, and sliding doors to the backyard. The updated kitchen has white cabinets, granite counters, a breakfast bar, and big windows, plus stainless steel appliances—electric range, fridge, and microwave. The dining room opens to the backyard via the same sliders, great for outdoor meals. The primary bedroom offers closet space and backyard views, with a sleek en-suite bath featuring floor-to-ceiling tile, a walk-in shower, and a floating cabinet. Three more bedrooms share a bath with a tub-shower combo; any can double as an office. The two-car garage has finished walls, a coated floor, a sink, and storage racks. Outside, a near 10,000-sq-ft lot with Redwood trees, a Koi Pond, garden boxes, and a hot tub-ready pad feels like a private park. Low-maintenance plants and a side yard for a boat complete it. Near Neil Armstrong Elementary, Pine Valley Middle, and California High with its Olympic Pool, it’s close to parks, shops, dining, and the 580/680 freeways. Open House Thur, Apr 24, 10-1p | Sat-Sun, Apr 26-27, 1-4p.

RS-7
Single-Family Residential Zone
The RS zone is applied to areas of the City appropriate for single-family residential land uses in neighborhoods at a density of three to six units per net acre, subject to appropriate standards. The specific allowable density for each parcel is shown on the Zoning Map by a numerical suffix residential density designator (see Section D2-8). Minimum lot size for new parcels ranges from 3,500 to 12,000 sq ft. Depending upon the applicable residential density designator, the RS zone is consistent with and implements the Single Family Low Density, Single Family Low-Medium Density, and Single Family Medium Density land use classifications of the General Plan.
