Petaluma has a well-preserved, historic city center which includes many buildings that survived the 1906 San Francisco earthquake.

Petaluma is today the location of many distinguished, well-preserved pre-1906 buildings and Victorian homes on the western side of the river. The downtown area has suffered many river floods over the years and during the Depression commerce declined. A lack of funds prevented the demolition of the old homes and buildings. In the 1960s there was a counter-culture migration out of San Francisco into Marin County and southern Sonoma County, looking for inexpensive housing in a less urban environment. The old Victorian, Queen Anne and Eastlake houses were restored. Historic iron-front buildings in the downtown commercial district were also rescued. Traffic and new home development for the most part was rerouted to the east of downtown by the construction of the 101 freeway. The downtown Petaluma Historic Commercial District is on the National Register of Historic Places.

Petaluma pioneered the time-controlled approach to development. After Highway 101 was re-aligned as a freeway in 1955, residential development permits tripled, from 300 in 1969 to 900 in 1971. Because of the region's soaring population in the sixties, the city enacted the “Petaluma Plan” in 1971. This plan limited the number of building permits to 500 annually for a five-year period beginning in 1972. At the same time Petaluma created a redbelt around the town as a boundary for urban expansion for a stated number of years. Similar to Ramapo, New York, a Residential Development Control System was created to distribute the building permits based on a point system conforming to the city's general plan to provide for low and moderate income housing and divide development somewhat equally between east and west and single family and multi-family housing.
