Description

1436 Western Avenue is a ±16-acre residential development site located within an established area of Petaluma, California. The property lies under Sonoma County jurisdiction and is zoned AR (Agriculture and Residential District) with a Rural Residential general plan designation, allowing for low-density residential development. Its size, configuration, and surrounding infrastructure support a variety of residential development strategies, including a conceptual eight-lot subdivision designed under current zoning standards. The site is bordered by multiple roadways, providing flexible access and design potential. Located minutes from Downtown Petaluma, the property benefits from proximity to retail, dining, employment centers, and a wide range of public and private schools. Additionally, the site offers potential future upside through annexation into the City of Petaluma, which could allow for increased residential density subject to approvals. This combination of scale, location, and optionality positions the property as a compelling long-term residential investment opportunity.
