Penngrove is a small 2 block town just North and East of Petaluma. It’s on the East side of the 101 and is South of Cotati at the foot of Sonoma Mountain. There is a pub, a couple of restaurants and a Main Street. Along with the chicken and egg industry, Penngrove was a source of basalt paving stones, which were used to pave the streets of major cities in the Bay Area, including San Francisco. To this day, many dilapidated chicken houses dot old farms and country roads in the area. Though Penngrove is rich with history, it has yet to be revitalized to the extent most other small wine country cities boast. Most of the 1,045 homes in Penngrove are spread out on large parcels and were built between the 1890 and 1940. In the 80s and 90s many folks from the Bay Area discovered Penngroves’ vast bucolic pastures, large parcels and, sadly, replaced those historic homes with large custom lifestyle homes.
