East Petaluma Homes: Subdivisions, Creeks and the SMART Line
East Petaluma is the part of the City of Petaluma that lies east of Highway 101, mostly in ZIP code 94954, and it is the side of town where Petaluma’s tract subdivisions spread from the 1960s on. It is incorporated city land, so Petaluma handles planning, permits, water and sewer. The area runs from the freeway out toward Adobe Road and the open land at the city edge, with the Petaluma North SMART station on Corona Road at its northern end.
Buyers here are usually comparing one tract house with another, so the details that separate them are lot, year built, any homeowners association, creek and flood exposure, and how far the house sits from the train and the freeway. This guide walks through those details and what a seller should line up before listing. For the city as a whole, start with our Petaluma real estate guide.

Where East Petaluma begins and ends
Petaluma splits informally into two halves. The older half, with the historic districts, is covered in our West Petaluma guide. The east side is the newer half, and Highway 101 is the line most people use.
The strip between the river and the freeway is mixed. It holds the Lakeville Street corridor, commercial and industrial land, and some housing. Most people treat everything past the freeway, from North McDowell Boulevard out toward Adobe Road and the city edge, as the east side proper. ZIP codes don’t follow the freeway exactly: SMART lists the Downtown Petaluma station at 220 Lakeville Street, between the river and the freeway, with a 94952 address.
At the outer edge, the city meets unincorporated Sonoma County. A house with a Petaluma mailing address out there may be under county rules, on a well and septic system, and outside the city’s transfer tax. Check the tax bill or the city limits before you rely on any city rule in this guide.
How the east side was built
The housing on this side of town reflects a growth story that ended up in federal court. In Construction Industry Association v. City of Petaluma, a builders’ challenge to the city’s growth-control plan, Judge Burke of the U.S. District Court for the Northern District of California issued findings of fact on April 26, 1974. Finding 3 says earlier policies let the eastern portion of the city become “densely populated by a sea of tract homes.”
A table in the same findings shows annual housing completions in Petaluma rising from 270 units in 1964 to 591 in 1970 and 891 in 1971. The city’s response, the Petaluma Plan, included an annual 500-unit building limit. The district court ruled against the plan, but the Ninth Circuit reversed that judgment on October 2, 1975, and the plan stood. With building rationed year by year, later east-side subdivisions tended to come in smaller phases rather than one burst.
What the housing stock looks like
- Earlier tracts. Subdivisions from the 1960s, like tract housing of that era across California, tend toward single-story plans on regular lots with attached garages. Remodels are likely after several decades of ownership, so the permit history matters more than the original plan.
- Later subdivisions. Tracts approved in later decades may use larger floor plans or a planned-district layout. Where a homeowners association exists, it may maintain common landscaping, private streets or shared amenities.
- Townhomes and condominiums. Attached homes with association dues, reserves and rules that a buyer must review before removing contingencies.
- Newer infill. Smaller projects on leftover parcels inside the city’s urban growth boundary, since large new tracts outside it are off the table.
These are general descriptions, not a survey of every tract, and we have not verified the build years of individual subdivisions. Two houses on the same street can differ by decades if one was rebuilt, so check the assessor’s year built, the permit file and any HOA documents for each property.
Zoning and what you can add
Petaluma’s Implementing Zoning Ordinance sets up Residential 1 through Residential 5 zones, a Mobile Home zone, Business Park and Industrial zones, a Floodway zone, and Planned Unit Districts and Planned Community Districts. On the east side that last category deserves attention, because a subdivision approved as a planned district may follow its own development plan rather than only a base zone.
That distinction matters if you want to add a second unit, a pool house or a second story. A planned district’s development plan and any HOA covenants can set setbacks, heights or design rules that go beyond the base zone. State law has made accessory dwelling units easier to permit, and our ADU investment guide covers the numbers, but an HOA’s design rules can still shape what the unit looks like.
Before you write an offer that depends on an addition, ask the Planning Division what zone and plan apply to the parcel and read the CC&Rs.
Creeks, the river and flood maps
Flood exposure on the east side comes less from the main river channel and more from the creeks that cross the subdivisions on their way to it. The city says its mapped floodplain follows the Petaluma River and that it has seen five major floods since 1982.
Two of the city’s flood projects sit on or near this side of town:
- Capri Creek. The city describes this project as designed to reduce out-of-bank flooding in larger storms from east of North McDowell Boulevard to Maria Drive.
- Denman Reach. Aimed at flooding along Industrial Avenue. The city bought five parcels beside the river and widened the floodplain so high water spreads into open space.
The city is also updating its floodplain maps with newer modeling and says it will use the results in land use decisions. A parcel’s mapped status could therefore change, so look at the current FEMA Flood Insurance Rate Map for the address through FEMA’s Flood Map Service Center.
The city also warns that localized flooding can reach property outside a mapped zone. Ask the seller about past water in the garage or crawlspace, request any elevation certificate, and get a flood insurance quote during escrow. Our North Bay flood zone guide explains zone letters, premiums and the 30-day waiting period.
Fire hazard maps
The state’s updated fire hazard severity zone maps for Petaluma’s local responsibility area came out in February 2025, and the city links a viewer for them. The flatter subdivisions east of the freeway are worth checking anyway, especially near open grassland at the edge. See our guide to North Bay fire hazard severity zones for what a High or Very High designation adds to a sale.
Parks, open space and landmarks
| Place | Address | What is there |
|---|---|---|
| Lucchesi Park | 320 North McDowell Blvd | Man-made pond, tennis, pickleball and handball courts, a synthetic turf field, Little League and Miracle League fields, two playgrounds, walking paths, and the Petaluma Community Center and Senior Center |
| Shollenberger Park | 1400 Cader Lane | 165-acre open space beside the river, with a two-mile loop trail and a one-mile cutoff; together with Alman Marsh and the Ellis Creek Water Recycling Facility the city calls the area the Petaluma Wetlands |
| Petaluma Adobe State Historic Park | 3325 Adobe Road | Headquarters of Vallejo’s Petaluma Rancho, described by State Parks as the largest private rancho in California between 1834 and 1846; museum, visitor center and picnic areas, open daily 10 a.m. to 5 p.m. |
The city says Shollenberger is its largest and most visited park. Lucchesi Park doubles as a civic hub because the community and senior centers sit inside it.
Getting around: SMART, buses and Highway 101
The Petaluma North SMART station at 320 Corona Road held its grand opening on January 10, 2025, giving the north end of the east side its own rail stop. SMART advertised free parking at the station but warned that spaces are limited.
From there, trains run north as far as Windsor and south through Marin to Larkspur, where the Connect Larkspur shuttle links the station with the ferry terminal. Day-use parking at SMART lots is free, and overnight parking is a $5 flat rate through the ParkMobile app. For homes in the southern part of the east side, the Downtown Petaluma station on Lakeville Street may be closer. Our page on homes near SMART and the ferry compares commute options.
Highway 101 is the main driving route. Just north of the city are Penngrove, an unincorporated community, and the City of Rohnert Park, whose SMART station is at 900 Enterprise Drive.
Local rules and costs
| Item | East Petaluma (inside city limits) |
|---|---|
| Government | City of Petaluma, Sonoma County |
| Water and sewer | City of Petaluma; wastewater treated at Ellis Creek Water Recycling Facility |
| City transfer tax | $2.00 per $1,000 of value (Municipal Code 4.20.020); existing loans that stay on the property are counted, not deducted |
| County transfer tax | $1.10 per $1,000 ($0.55 per $500), with assumed loans deducted |
| Rentals | City tenant protections from the first day of a protected tenancy; no local rent cap listed by the city |
| Flood and fire | FEMA flood map for the parcel; 2025 fire hazard severity zone viewer linked by the city |
On a $850,000 east-side sale with no assumed loan, the city tax is $1,700 and the county tax is $935, or $2,635 together. Sellers customarily cover transfer tax in Diamond’s North Bay markets. Custom varies and the split is negotiable, so write it into the purchase contract. Our California transfer tax guide shows how it is calculated.
If you are buying an east-side house to rent out, read the city’s tenant protections first. They allow a landlord to end a protected tenancy only for listed for-cause or no-fault reasons, and a no-fault termination brings relocation pay of 250% of a month’s rent, capped at $9,000. One listed exemption covers an owner of three or fewer units who is not a REIT, a corporation or an LLC with a corporate member, provided the exemption is stated in writing to the tenant. Our guide to just cause rules for landlords explains the basics. This is general information, not legal advice; ask a California landlord-tenant attorney before you buy a rented home or serve any notice.
Selling a home in East Petaluma
East-side buyers compare floor plans and condition closely because many houses started out alike. The seller’s job is to show what makes this one different, and to have the paperwork ready.
- Price against the right tract. Use recent sales from the same subdivision or era and similar square footage, and adjust for remodels and lot size. Our comparative market analysis guide explains the method.
- Gather HOA documents early. If there is an association, order the resale package so the buyer can review budgets, reserves and rules on time.
- Match improvements to permits. Garage conversions, added rooms and second units can turn up in older tracts. Unpermitted work affects financing and disclosure.
- Document flood history. Pull the FEMA zone, any elevation certificate and any flood claims so your seller disclosures and the natural hazard report line up.
- Consider pre-listing inspections. Roof, sewer lateral and pest reports reduce surprises; see our pre-listing inspection guide.
We did not find a Petaluma point-of-sale inspection ordinance for houses, but confirm current city requirements before listing. Diamond may refer you to partners we work with, such as inspectors and contractors; you’re free to choose any provider.
Questions people ask

Is East Petaluma inside city limits?
Most of it is. Near the outer edge, some Petaluma-addressed properties are on unincorporated county land, where county rules apply and the city transfer tax does not.
Is East Petaluma in a flood zone?
It depends on the parcel. Creeks such as Capri Creek cross the east side, and the city has a flood project there. Check the FEMA map for the address and ask about past water intrusion.
When did the Petaluma North SMART station open?
Its grand opening was January 10, 2025. The station is at 320 Corona Road, and SMART said parking is free but limited.
Do East Petaluma homes have HOAs?
Some do, typically condominium and townhome projects and some planned developments. Many detached-house tracts have none, so check the title report and the listing for CC&Rs and an association.
What is the transfer tax on an East Petaluma sale?
Inside city limits it is $3.10 per $1,000 in total: $2.00 to the city and $1.10 to the county. The seller customarily pays in the North Bay, but it is negotiable.
How is East Petaluma different from West Petaluma?
The east side is mostly subdivision housing from the 1960s onward. The west side holds the older houses and the city’s residential historic districts, where exterior changes can need historic review.
