Petaluma, CA Housing Market 2026: What Homes Actually Sell For

If you invest in or around Petaluma, the number that matters is what homes actually close for, not what sellers are asking. Here is what Petaluma sale prices look like right now, built from the closings Resideline tracked over the last six months, as of September 2026.

The snapshot

• •Closings tracked, last 6 months: 288
• •Median sold price, last 6 months: $850,000
• •Median sold $/sqft, last 6 months: $528
• •Middle half of sales closed between: $670,000 and $1,050,000

What the numbers say

Resideline tracked 288 closed sales in Petaluma over the last six months, with a median closing price of $850,000. That median is the midpoint of what buyers actually paid, not what sellers hoped to get, which is why it moves differently from the asking prices you see on listing sites. The middle half of those sales closed between $670,000 and $1,050,000. That spread matters more than the headline median: where a specific property sits inside it decides whether the citywide number helps you or misleads you. These are the closings Resideline tracks and may differ from complete county or municipal records. 81% of the Petaluma closings we track here are single-family houses, so these figures primarily reflect that segment, and the citywide $/sqft figure primarily reflects that segment as well. Across the 288 closings with usable living area, the middle half sold between $441 and $638 per square foot.

Figures last updated September 6, 2026 from closings Resideline tracked.

How long a sale takes here

• •Listed to under contract: a median of 12 days, across 193 Petaluma closings Resideline tracked in the last six months
• •Contract to closing: a median of 17 days, across 190 Petaluma closings Resideline tracked in the last six months

The Petaluma angle

Petaluma gave us 288 tracked closings over the last six months, a median closed sale price of $850,000, and a middle half running from $670,000 to $1,050,000.The practical reading is that neither the top nor the bottom of the band is exotic, so an estimate anywhere between $670,000 and $1,050,000 is not by itself remarkable and needs matched comps to become an argument. Save your skepticism for numbers outside the band, and require an explanation, not just enthusiasm, before accepting one.

From market read to offer price

A market read is the backdrop. The decision still comes down to one property and one number: what it is actually worth and what you should pay. Every Resideline report opens with this same market snapshot for the subject's exact ZIP code, then gives you the property's value, the sold comps behind it, and a market rent estimate. Pricing a specific deal? The free ARV calculator and rental property calculator run the numbers in about a minute.

And we show our work. Every estimate is frozen while the home is for sale and graded against the real closing price after it sells. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.

Run any Petaluma address through Resideline and you will see the local market and the property's value together, in one report.

The local market statistics in this report are calculated from closed sales tracked by Resideline. Transaction coverage may differ from complete county or municipal records.

Every local market figure on this page is computed from closed sales Resideline tracked in Petaluma over the last six months, and is refreshed when the data is. The closings we track within the Petaluma city limits are not limited to listing-service sales: they also include foreclosure deeds, estate and family transfers, and other off-market sales that portal medians exclude, which is why 12% of the 288 closings in this window never appeared on a listing service, and the median of MLS-listed sales alone was $875,000.
