about this property

Modern Wine Country Living with Income & Lifestyle Potential
Set on two scenic acres in the hills of Cotati, just outside Petaluma and Penngrove, this distinctive Wine Country estate combines timeless design with exceptional versatility—featuring two fully independent homes ideal for multigenerational living, guest use, or rental income opportunities.

Completed in 2018, the property includes a beautifully appointed 3BD/3BA main residence (~3,418± sq. ft.) and a stunning 2BD/2BA guest cottage (~840± sq. ft.). Whether you're looking for a full-time residence with built-in income potential, a multi-home family compound, or a turnkey rental-ready property, this estate delivers elevated living and unmatched value.
Inspired by the architectural style of Howard Backen—renowned for luxury destinations like Solage Calistoga and Meadowood—the main home is a refined retreat with soaring open-beam ceilings, wide-plank French oak floors, and expansive Marvin windows that bring in natural light and vineyard views.

The great room features a gas fireplace with natural stone hearth, a custom refreshment bar, and generous space for entertaining. At the heart of the home is the chef’s kitchen: a 14-foot quartz island, custom 4-burner Blue Star range with grill and griddle, dual ovens, subway tile backsplash with pot filler, Fireclay apron-front sink, GE appliances, and handcrafted Rhyne cabinetry from Sebastopol.
A seamless connection to the outdoors invites daily enjoyment of Wine Country’s best: a pergola-shaded patio with putting green, a covered breezeway for morning coffee, wraparound porch for golden hour gatherings, spa under the stars, and a sunset deck 
among olive trees and vines.

The private main-level primary suite features sliding glass doors, a walk-in closet, and a spa-style bath with soaking tub, radiant-heated concrete floors, and oversized walk-in shower with multiple showerheads. A bonus room offers potential for a fourth bedroom or home office, and a separate mudroom/flex space adds utility.

Upstairs, two bedrooms share a Jack & Jill bath and a central loft area with dual built-in desks and custom oak cabinetry—ideal for working or learning from home.

The detached 2BD/2BA guest cottage mirrors the quality and design of the main home with Blue Star range, quartz counters, Carrera marble backsplash, apron-front sink, and barn-style doors. With separate entries for each bedroom, the ADU offers flexible rental options, privacy for extended family or guests, or the ability to offset ownership costs through monthly income.

Agricultural Highlights:
  • Boutique vineyard planted with prized Pinot Noir clones: Pommard, Dijon, and Merry Edwards
  • Mature olive grove (30+ trees), producing 50+ gallons of olive oil
  • 17 fruit trees, 100+ lavender plants, and raised garden beds
  • Open-air livestock barn with water and a recently replaced roof

Property Features:
  • Large secondary barn with water
  • Solar-powered gated entry
  • Bocce ball court
  • Ground-level radiant heat (main home), efficient wall heat (guest cottage)
  • Smart home systems: Nest thermostats, ADP security, smart switches, Leviton lighting
  • Water filtration and advanced septic systems
  • Air conditioning (main house)
  • Two-car garage with dual EV charging, plus additional outdoor EV access

Location:
Located just minutes from downtown Cotati, Penngrove, Petaluma, and Highway 101, the property offers both tranquility and connectivity—close to Sonoma State University, the SMART train, and local tasting rooms. You're under 30 minutes from Sonoma County Airport, less than an hour to the coast, and just over an hour from San Francisco.
Whether you're seeking a primary residence, family compound, luxury rental, or all of the above, this remarkable property presents a rare combination of design, flexibility, income potential, and location—offering the ultimate modern Wine Country lifestyle.
