A striking reimagination of classic Eichler living, 4100 Phoenix St blends iconic mid-century modern architecture with thoughtful updates for today. Set on an expansive 8,000-square-foot corner lot, the 4-bedroom, 2-bath residence offers 1,795 square feet of living space, plus an enclosed, climate-controlled atrium that creates a versatile year-round extension of the home. Inside, signature Eichler details remain at the heart of the design, including post-and-beam construction, tongue-and-groove ceilings, globe lighting, and dramatic walls of glass that fill the interiors with natural light and connect the living spaces to the outdoors. A recently remodeled modern kitchen features brand-new appliances, while both bathrooms have been beautifully updated. The expanded primary ensuite bath offers a spa-like retreat with a luxurious soaking tub and spacious walk-in shower. Modern improvements include updated electrical system, dual pane windows, newer heat pump providing central heating and cooling, and low-maintenance vinyl exterior siding. A rare addition for an Eichler, attic space provides abundant storage without sacrificing the home’s original footprint. Outside, freshly landscaped, low-maintenance grounds offer multiple areas for relaxing, dining, and entertaining. A generously sized attached two-car garage provides additional functionality, while gated side access offers dedicated space for boat or RV parking. Distinctive, spacious, and thoughtfully updated, this home offers the enduring appeal of Eichler architecture with modern comfort, exceptional storage, and flexible indoor-outdoor living.

RS7
Residential Single-Family District
The RS district is applied to areas of the city appropriate for single-family residential uses in neighborhoods at densities of 2.5 to 10 units per net acre, subject to appropriate standards. The RS zoning districts generally apply to the single-family residential districts with development existing at the time of the adoption of this development code. The specific allowable density for each parcel is shown on the zoning map by a numerical suffix residential density designator RS-7 corresponding to the minimum lot size 7000. The RS district is consistent with and implements the low density residential (LDR) land use designation of the general plan.
