Petaluma sits at the southern edge of Sonoma County, where Northern California's wine country meets a well-preserved downtown that still feels like a genuine small city rather than a weekend destination. Founded through a Mexican land grant in the 1830s by Mariano Guadalupe Vallejo, the city built its early identity around agriculture and later earned the nickname "Egg Basket of the World" for its poultry industry. That history lives on in the architecture, particularly in the Neo-Classical and Spanish Colonial Revival buildings lining the historic core, and in annual events like Butter and Eggs Days that draw the whole community together.
Neighborhoods range from walkable downtown blocks close to the Petaluma River to quieter residential stretches on the east and west sides of the city. The housing stock reflects that range, offering craftsman bungalows, townhomes, and apartment communities that suit a variety of preferences.
