Petaluma CA Real Estate & Homes For Sale

Petaluma is an incorporated Sonoma County city that provides its own planning, permits, water and sewer, with growth limited by a voter-approved urban growth boundary. Homes range from historic west-side neighborhoods to east-side tract subdivisions, and sales pay both county and city transfer taxes, with just-cause tenant protections from day one.

Petaluma’s main areas and housing stock

Locals talk about the west side and the east side, and the split is real in the housing. The river and downtown sit between the two, with Highway 101 running north to south east of downtown. Here is how the main areas differ.

Downtown and the historic districts

Petaluma has three historic districts. The Petaluma Historic Commercial District, listed on the National Register of Historic Places in 1995, covers much of downtown: 96 contributing buildings on about 23 acres, built from the mid-1800s to the end of World War II.

The “A” Street Historic District, adopted by the city in 1986, lies south and east of downtown and holds homes, churches and apartments built between 1860 and 1925. The Oakhill-Brewster Historic District, a local preservation district adopted in 1990, is north and west of downtown.

Both residential districts have their own city preservation guidelines and standards. If you plan exterior changes to a house in one of them, read those guidelines before you write an offer and ask the city’s planning staff what review the work would need.

West Petaluma (94952)

West of the river is where most of the city’s pre-1925 houses and both residential historic districts are. Toward the hills, the city edge meets open land and Helen Putnam Regional Park, whose main trailhead is at 411 Chileno Valley Road and second trailhead at 373 Windsor Drive.

Expect older houses with the inspection items that come with age, more varied lot sizes, and higher prices per square foot than across town. Our West Petaluma guide has more detail.

East Petaluma (94954)

East of Highway 101 the city is mostly tract subdivisions, many of them laid out in the post-war decades. A federal court’s 1974 findings, in a challenge to the city’s growth-control plan, describe the eastern portion of Petaluma having filled with tract homes by the early 1960s and annual housing completions rising from 270 units in 1964 to 891 in 1971.

Today the east side has the Petaluma North SMART station at 320 Corona Road and Petaluma Adobe State Historic Park at 3325 Adobe Road. Our East Petaluma guide has more detail.

Scott Ranch and the western edge

Scott Ranch is a 58-acre property at Windsor Drive and the D Street extension, next to Helen Putnam Regional Park. The City Council certified the environmental impact report for a 28-home plan, down from 93 homes proposed in 2003, and about 47 acres were set aside for open space and a park extension toward D Street. We have not confirmed that construction or sales have begun, so treat Scott Ranch as an approved project, not an established neighborhood.

Condominiums and mobile homes

Condominiums and townhomes come with their own association documents, which the seller must provide. Mobile homes sit in parks on leased spaces.

Five of them (Leisure Lake, Petaluma Estates, Royal Oaks, Cottages of Petaluma and Youngstown) are in the city’s Senior Mobile Home Park Overlay, which requires at least 80% of spaces to be occupied by at least one person 55 or older. Our guide to mobile homes in Sonoma County explains titling, park approval and financing.

Outside the city limits

Some homes with a Petaluma mailing address are on unincorporated county land, outside the growth boundary. There the county, not the city, sets the rules: no city transfer tax, the county’s own tenant protections (Ordinance 6496, adopted in 2024) and permit rules, and usually a private well and septic system instead of city water and sewer.

Check the tax bill or the city limits map for any address. North of town, Penngrove is the main unincorporated community, and our page on wells, septic and rural utilities covers those systems.

Prices and competition by side of town

Petaluma’s two ZIP codes behave like separate markets, so a comparable sale from across the river can mislead in either direction. Redfin’s latest figures:

MeasureCitywide (Sept 2026)94952, west (Aug 2026)94954, east (Aug 2026)
Median sale price$914,564$1,085,000$883,500
Change from a year earlier+3.9%+5.9%+3.9%
Median price per square footNot used here$638$472
Sold above list price57.3%50.8%58.7%
Median days on market283627

Citywide, the sale-to-list ratio was 101.8% and 119 homes sold in September, but 28.9% of listings also took a price cut. Both are true at once: well-priced homes draw competing offers, and homes priced above the comparable sales sit. For an address-specific number, use comparable sales from the same side of town and the same era of construction.

Growth limits: the urban growth boundary

Petaluma has tried to manage growth for decades. Its early-1970s Petaluma Plan held new housing to a 500-unit annual figure tied to an urban extension line, and the 1974 federal court findings describe that limit and the market demand it held back. The Ninth Circuit reversed that ruling in 1975 (522 F.2d 897), and the plan stood. The modern tool is the urban growth boundary, which voters first approved in 1998 and renewed in 2010 through December 31, 2025.

In November 2024 voters renewed the boundary for another 25 years as Measure Y, with no change to its line; Greenbelt Alliance reported it passing with nearly 70% of the vote in preliminary results. For a buyer this has two practical effects.

Inside the line, most new housing comes as infill and smaller projects rather than large new tracts. Outside it, land stays rural, so a ranch or acreage parcel on the edge is unlikely to become a subdivision.

Flooding and wildfire hazard

The Petaluma River

The city counts five major floods since 1982, and the 1982 storm alone caused about $28 million in damage. The Payran reach flood project, finished in early 2016 at a cost of about $41.5 million, reworked 3,600 feet of the river north from Lakeville Street, widening the channel and adding floodwalls and two emergency pumping stations, and replaced the Payran and Lakeville Street bridges. The Argus-Courier reported at the time that dozens of homes and businesses could come out of the high-risk flood designation.

Work continues elsewhere. The Denman Reach project bought five riverside parcels and widened the floodplain near Industrial Avenue, and the Capri Creek project targets out-of-bank flooding from east of North McDowell Boulevard to Maria Drive. The city is also updating its floodplain maps with a two-dimensional model and studying sea level rise where tides reach.

What to do: look up the address on the FEMA Flood Map Service Center, ask the seller about past water intrusion and any flood insurance policy, and get an insurance quote during your contingency period. The city warns that localized flooding can reach property outside mapped zones and that an inch of water can cause up to $25,000 in damage. More in our North Bay flood zone guide.

Fire hazard severity zones

The State Fire Marshal released new maps of moderate, high and very high fire hazard severity zones in Petaluma’s local responsibility area to the Petaluma Fire Department on February 24, 2025. Check the zone for any address in the state’s map viewer. A zone designation can bring state minimum fire-safety requirements for the property.

The State Fire Marshal’s page points to a Department of Insurance notice that the maps do not affect insurance rates or availability. See our guide to fire hazard severity zones in the North Bay.

Local rules: transfer tax, tenants, mobile homes and short-term rentals

Transfer tax

A Petaluma sale pays two documentary transfer taxes. The county charges $0.55 per $500 of value, or $1.10 per $1,000, less any loan assumed. The city adds $2.00 per $1,000 under Municipal Code section 4.20.020.

On a $900,000 sale that is $990 to the county plus $1,800 to the city, or $2,790 in all. In Diamond’s North Bay markets the seller customarily pays, but it is negotiable and custom varies, so settle it in the purchase contract. More in our California transfer tax guide.

Tenant protections

Petaluma’s Residential Tenancy Protections, Chapter 6.60 of the Municipal Code, took effect October 12, 2022, and were amended effective June 15, 2023. They require just cause to end a tenancy from the first day, earlier than state law requires. For no-fault terminations, such as an owner moving in or withdrawing the unit from the rental market, the landlord owes relocation assistance of 250% of one month’s rent or $9,000, whichever is less.

There are exemptions, including small property owners with three or fewer units who are not a REIT, a corporation or an LLC with a corporate member and who give tenants the required written notice in the rental agreement, and units where the owner shares a kitchen or bathroom with the tenant. The city’s tenant rights page lists no local cap on rent amounts, so the state cap in Civil Code 1947.12 applies where it covers the unit: 5% plus inflation or 10%, whichever is lower, in a 12-month period, with exemptions for housing built in the last 15 years. Landlords and buyers of rentals can read our guide to just-cause eviction rules.

Mobile home space rents

Chapter 6.50 limits space-rent increases in Petaluma’s mobile home parks to the lesser of 70% of the change in the Consumer Price Index or 4%, no more than once every 12 months. The city’s program page says that since January 1, 2025 all spaces are covered regardless of lease term, and it set the allowance at 2.2% through June 30, 2025; ask the city’s housing staff for the current figure.

Short-term rentals

Petaluma allows vacation rentals with a city permit in residential, planned unit development and mixed-use zones. A hosted rental, where the permit holder lives on site, may rent up to two bedrooms. A non-hosted rental of the whole home is limited to 90 days a calendar year, with a local manager within 45 miles who answers complaints within an hour.

Accessory dwelling units permitted after September 7, 2017 cannot be used as short-term rentals. Owners also need a business license, must pay the city’s transient occupancy tax and must show the permit number in ads. For the rest of the county, see our Sonoma County vacation rental guide.

These rules change. This is general information, not legal advice; talk to a California real estate attorney about a specific tenancy or permit.

Utilities, schools and getting around

Water, sewer and power

Inside the city, Petaluma provides water and sewer. Most of the city’s drinking water is imported from the Russian River system through Sonoma Water, with city wells used during shortages and peak summer demand.

Wastewater goes to the Ellis Creek Water Recycling Facility, which treats it with filtration, ultraviolet disinfection and polishing wetlands, and the city delivers recycled water to parks, schools, landscapes, vineyards and farms. Sonoma Clean Power is the public power provider for Sonoma and Mendocino counties.

School districts

Petaluma City Schools is made up of the Petaluma City Elementary School District and the Petaluma Joint Union High School District, whose schools include Casa Grande High School and Petaluma High School. Some Petaluma addresses fall in separate elementary districts, so confirm the assigned district for a specific address with the district office.

Train, bus and highway

SMART trains stop at Downtown Petaluma and at Petaluma North, which held its grand opening on January 10, 2025. Both stations have free day-use parking and $5-a-night overnight parking through the ParkMobile app, for up to five nights. The downtown station is next to the Petaluma Transit Mall on Copeland Street, served by Golden Gate Transit, Sonoma County Transit, Petaluma Transit and the free LumaGo shuttle.

Heading south, SMART ends at Larkspur, where the Connect Larkspur shuttle meets the ferry terminal. Sonoma County Transit runs buses from Petaluma to Sonoma (Route 40X), to Santa Rosa Junior College and Sonoma State (Route 44) and up the 101 corridor (Route 48).

The Census puts Petaluma’s mean commute at 30.7 minutes. See also our page on homes near SMART and the ferry.

Selling a home in Petaluma

Most of the work in a Petaluma sale is pricing to the right side of town and getting the paperwork in order before the first showing.

  1. Price from the right comparables. Use sales from the same ZIP code, era and home type. The two ZIP codes’ median prices per square foot were $166 apart in August 2026.
  2. Pull permits and district records. For a home in the “A” Street or Oakhill-Brewster district, collect any approvals for past exterior work. Buyers will ask.
  3. Document flood and fire status. Pull the FEMA flood zone, any insurance claims history and the 2025 fire hazard zone so the disclosures and the natural hazard report match.
  4. Settle tenancy questions early. If the home is rented, Chapter 6.60 applies from the first day of the lease. Decide whether to sell with the tenant in place, and get legal advice before giving any notice.
  5. Plan the transfer tax and your next move. The $3.10 per $1,000 is a seller cost by custom here, though negotiable. If you are 55 or older and buying a replacement home in California, Proposition 19 may let you carry your property tax base with you; see our Prop 19 base year transfer guide.

Diamond prepares a pricing analysis by side of town, coordinates pre-listing inspections and disclosures, and markets the home through the MLS and its own database of likely buyers. Diamond may refer you to partners we work with; you’re free to choose any provider. For the selling process countywide, see selling a home in Sonoma County.

Questions people ask

Is Petaluma part of Sonoma County or Marin County?

Sonoma County. Petaluma is an incorporated city in southern Sonoma County near the Marin County line, with its own city government, planning department, and water and sewer service.

What is the median home price in Petaluma?

Redfin put the citywide median sale price at $914,564 in September 2026, up 3.9% from a year earlier. In August 2026 the west-side ZIP code, 94952, had a median of $1,085,000 and the east-side ZIP code, 94954, had $883,500.

Is Petaluma a competitive market?

For well-priced homes, yes. In September 2026, 57.3% of homes sold above list price and the median home sold in 28 days, but 28.9% of listings also had price cuts.

What is the difference between West Petaluma and East Petaluma?

The west side, ZIP 94952, holds most of the pre-1925 houses and the residential historic districts and sells at a higher price per square foot. The east side, ZIP 94954, is mostly subdivisions built from the 1960s onward, east of Highway 101.

How much is the transfer tax in Petaluma?

$3.10 per $1,000 of value: $1.10 to the county and $2.00 to the city. On a $900,000 sale that totals $2,790. The seller customarily pays in the North Bay, but it is negotiable.

Does Petaluma have rent control?

Not on rent amounts for apartments or houses; the state cap in Civil Code 1947.12 applies where it covers the unit. Petaluma does require just cause to end a tenancy from the first day and relocation pay for no-fault terminations, and it caps mobile home space-rent increases at the lesser of 70% of inflation or 4%.

Can I run a vacation rental in Petaluma?

With a city permit, yes, in residential, planned unit development and mixed-use zones. A non-hosted whole-home rental is limited to 90 days a year, and ADUs permitted after September 7, 2017 are not eligible.

Is Petaluma in a flood zone?

Parts of it are. The Petaluma River and its creeks have flooded five major times since 1982. Look up each address on FEMA’s Flood Map Service Center and get a flood insurance quote during escrow.

How many SMART stations does Petaluma have?

Two: Downtown Petaluma at 220 Lakeville Street and Petaluma North at 320 Corona Road, which opened in January 2025. Both have free day-use parking.

What is the Petaluma urban growth boundary?

A voter-approved line, first adopted in 1998, outside which the city does not expand. Voters renewed it in November 2024 for another 25 years as Measure Y.

Where does Petaluma’s water come from?

Mostly from the Russian River system, imported through Sonoma Water, with city wells used during shortages and summer peaks. The city also supplies recycled water from the Ellis Creek facility for irrigation.

Are there 55+ mobile home parks in Petaluma?

Yes. Five parks are in the city’s Senior Mobile Home Park Overlay: Leisure Lake, Petaluma Estates, Royal Oaks, Cottages of Petaluma and Youngstown. Each must keep at least 80% of spaces occupied by at least one person 55 or older.

Which school districts serve Petaluma?

Petaluma City Schools, made up of the Petaluma City Elementary School District and the Petaluma Joint Union High School District. Some addresses are in separate elementary districts, so confirm by address.

If you are weighing a move to Petaluma, or want to know what your Petaluma home would sell for on its side of town, request a home valuation and we will price it from the sales that match it.

Permits, ADUs and remodels in Petaluma

Inside city limits, the City of Petaluma’s Planning and Building divisions apply the city’s Implementing Zoning Ordinance (IZO). For an unincorporated parcel, Permit Sonoma handles county land-use and building review. Confirm jurisdiction using the parcel boundary; the urban growth boundary and city limit have different planning functions.

ADUs and junior ADUs. A qualifying Petaluma parcel may use a state or local ADU pathway; residential zoning alone does not settle the unit count or permit eligibility. A building permit and an address assignment are both needed before construction (City of Petaluma, ADUs). Ask Planning to identify the current IZO Section 7.030 standards and the state-law pathway for the actual proposal:

  • Junior ADU: confirm the interior-conversion category, floor area, sanitation and any occupancy condition.
  • Attached or converted unit: confirm whether the proposal uses existing space or adds floor area, and which size and setback standards apply.
  • Detached unit: check the applicable footprint, height, access and utility requirements rather than treating one local maximum as the limit for every state-law pathway.
  • Site design: verify whether open-space, historic-design or other objective standards apply to this specific unit.

Historic districts. The city’s ADU historic-district FAQ distinguishes ADU processing from site plan and architectural review (SPAR), while identifying design criteria in IZO §7.030(O). Ask Planning which current criteria and state-law limitations apply to the proposed unit. For exterior work on the main house, check the historic district and project-specific review separately.

The city posts its residential building handouts for common projects. For a home with a converted garage or backyard unit, see buying a home with an ADU and unpermitted ADUs.

Luxury homes and estates in Petaluma

Petaluma’s higher-end property takes three forms in planning terms:

  • Older homes in the historic districts. Exterior work and ADUs there meet the extra design criteria above.
  • Larger homes on the west side. These include view lots near Helen Putnam Regional Park and Scott Ranch at the western edge (see our West Petaluma guide).
  • Ranch, dairy and rural estates outside city limits. Confirm county zoning, recorded agricultural restrictions and the actual water and wastewater arrangements for the parcel. Our city versus rural ownership guide explains the difference.

Due diligence that matters most on a high-value Petaluma purchase:

Ask Diamond Real Estate Group which permitted private-marketing options fit your property, goals and the applicable MLS rules. Availability of any particular listing is not guaranteed. For the county-wide view, see Sonoma County luxury homes. We can’t promise that any particular property will be available.

More Petaluma real estate questions

How do I choose a listing agent in Petaluma?

Look for one who prices in-city homes separately from rural parcels, knows the historic district and ADU rules, and handles flood and fire disclosures. Diamond Real Estate Group (broker Matthew Martinez, DRE #01869679) represents Petaluma sellers and buyers. Our list of Petaluma real estate agents is published by us and disclosed as such.

Can I build an ADU on my Petaluma lot?

A qualifying property may be eligible. The applicable unit count, floor area, setbacks, height and approval route depend on the existing or proposed dwellings and the state or local pathway. Confirm current requirements with Petaluma Planning and Building before treating an added unit as feasible, especially for historic property or a site with utility or access constraints.

Do I need design review for an ADU in a Petaluma historic district?

Site plan and architectural review isn’t required for a new ADU or JADU. An ADU on a landmark site or in a designated historic district must, however, meet the specific design criteria in IZO § 7.030(O). Ask Planning staff before you design one.

A West Petaluma listing example: 640 Jade Street

West Petaluma includes newer condominium communities as well as its better-known historic housing. Our June 22, 2026 Quarry Heights listing announcement shows that distinction in practice. The corresponding MLSListings record for 640 Jade Street, MLS BA326052175, identifies Matthew Martinez of Diamond Real Estate Group as the listing agent and describes a three-bedroom condominium built in 2016 with approximately 1,989 square feet.

Verified listing status: The public MLSListings record for 640 Jade Street reports a sale on September 11, 2026 and names Matthew Martinez of Diamond Real Estate Group, California DRE #01869679, as the listing agent. Status checked October 29, 2026.

The public marketing emphasized the primary suite, a private balcony, additional outdoor space and an attached two-car garage. Those features tell a more useful story than the west-side label alone: this was a home presented around flexible interior space and a low-maintenance setting, with a different ownership form and building era from an older detached house near downtown.

The comparison starts with the property type. For a similar search, look at condominium ownership and the association’s responsibilities alongside the home’s layout, outdoor areas and parking. Shared amenities can contribute to the setting, while the governing documents establish what belongs to the individual home and what is maintained collectively. That approach connects the neighborhood description with the actual property a buyer would own.
