Petaluma Closes Q2 2026 With 158 Sales and a $919,500 Median — While the Per-Square-Foot Rate Slipped Each Month

The tension hiding inside a solid quarter

On the surface, Q2 2026 looks straightforward: 158 closings, $176.1 million in total volume, a $919,500 overall median. Dig one layer deeper and two things pull in opposite directions. The median sale price rose every month — from $857,500 in April to $965,000 in June, a $107,500 climb across the quarter. The median price per square foot fell every month — from $557 to $550 to $546. What reconciles those two movements is square footage: as the quarter progressed, the homes that closed got larger on average. The per-foot rate softened even as headline numbers improved. That divergence is the story of Q2.

This report is drawn from county-recorded sales. The source carries no list prices and no days-on-market figures for this period; neither pricing discipline nor transaction speed can be assessed here.

The period at a glance

One hundred fifty-eight closings is a meaningful sample for a city of Petaluma's size, and the spread from $317,500 to $6,600,000 confirms that essentially every price tier was active during the quarter. The median lot of 6,500 square feet reflects that a large share of the activity was in established neighborhoods with modest parcels, though several of the top-end transactions involved acreage that pulled the average well above that figure.

The $176.1 million in aggregate volume was heavily influenced by the top of the roster. The quarter's single largest transaction — a multi-family property at 6614 Lakeville Highway at $6.6 million — accounted for roughly 3.7 percent of total volume on its own. Strip out the six closings at or above $2 million and the remaining 152 transactions still produced approximately $138 million, keeping the broad mid-market the engine of the quarter.

The sales

The table below shows the top 40 of 158 closings by sale price. It is not a complete record of the quarter.

Four transactions define the outer edges of this quarter's story.

6614 Lakeville Highway — the only multi-family closing in the period — recorded at $6,600,000 on June 2. At 10,792 square feet across 11 bedrooms, the $612-per-square-foot rate is notably lower than most of the high-end single-family closings, which is typical for income-producing property where gross square footage includes common and utility space.

555 Magnolia Ave posted the highest per-square-foot figure in the entire top 40: $1,871 on a 1,766-square-foot, two-bedroom house built in 1949, on a 64,468-square-foot lot. At 64,468 square feet, the lot is roughly 9.9 times the quarter's median recorded lot size of 6,500 square feet; at $3,304,000 the property sits third among single-family closings by price despite the structure ranking among the smallest in the top tier at 1,766 square feet.

14 Red Barn Court and 22 Red Barn Court closed the same day — June 6 — in what appears to be a phased or concurrent transaction on the same street. They share identical square footage (2,491 sq ft) and the same three-bedroom count but closed at $1,809,000 and $1,662,310 respectively, a $146,690 gap. No lot size is recorded for either, so the spread cannot be attributed to land area from this data alone.

1345 San Antonio Road achieved the highest per-square-foot rate among the conventionally sized luxury single-family closings — $924 on 3,694 square feet — producing a $3,412,500 close on June 17. That rate is 67 percent above the quarter's overall median of $552/sq ft.

Where the market split

By segment

Single-family detached homes dominated by every measure: 129 of 158 closings (82 percent of transactions), a $970,260 median, and a $562 median per square foot. The segment's price range spans more than $3.5 million, which is wide enough that the median obscures considerable internal variation — the 129-sale sample supports the figure, but the distribution is not tight.

The "Other" segment — 17 closings — carries a $772,000 median at $536/sq ft, sitting $198,260 below the single-family median. Its 1,383-square-foot median footprint is the smallest outside condominiums, which accounts for part of that gap.

Condominiums recorded 8 closings between $317,500 and $975,000, with a $703,000 median. Their $457/sq ft is the second-lowest rate of any segment, but their median square footage (1,707 sq ft) is larger than the "Other" segment — meaning the discount is in rate, not entirely in size.

Townhouses produced only 3 closings ($630,500 to $822,000). With exactly three sales, a median of $667,000 is technically calculable but rests on a very thin base; the range gives a more reliable picture of where townhouse transactions landed this quarter.

The single multi-family closing at $6,600,000 carries no meaningful segment median — it is a single data point.

By price band

The sub-$1 million band accounted for 92 of 158 closings — 58 percent of all transactions. Combined with the 43 closings in the $1M–$1.5M band, 135 of 158 sales (85 percent) landed below $1.5 million. The quarter was, in transaction count terms, a sub-$1.5M market with a high-profile upper tier.

The per-foot rate does not escalate cleanly with price. The $1M–$1.5M band ($535/sq ft) ran slightly below the under-$1M band ($541/sq ft), which reflects that many million-dollar closings in this period were larger homes where per-foot rates moderate as total size increases. The $1.5M–$2M band jumps to $686/sq ft — a 28 percent premium over the band below it — suggesting that the 13 closings in that range skewed toward smaller, high-rate properties rather than large estates. The $3M–$5M band reaches $924/sq ft across just 3 closings, driven significantly by 1345 San Antonio Road.

The single closing at or above $5 million recorded $612/sq ft — below the $3M–$5M band — consistent with the multi-family nature of that asset.

Across the quarter

Closings accelerated through the quarter: 46 in April, 49 in May, 63 in June. June alone represented 40 percent of the quarter's transactions.

The median sale price rose each month, from $857,500 in April to $965,000 in June — a $107,500 increase across ten weeks. The median price per square foot moved in the opposite direction every month: $557, $550, $546. The two series diverge because the mix of what closed shifted. June's 63 closings included a higher proportion of larger homes; those homes commanded higher absolute prices but lower per-foot rates. April's smaller cohort was weighted more toward compact, higher-rate properties.

Neither trajectory is independent of the other, and neither tells the full story without the other.

What it means

For sellers

One hundred fifty-eight closings over 91 days works out to roughly 1.7 transactions per day across all segments. Activity accelerated into June, with that month absorbing 40 percent of the quarter's closings. Single-family detached homes at a $970,260 median and $562/sq ft represented the segment with the deepest transaction record. The $1.5M–$2M band produced 13 closings at a median $686/sq ft — the sharpest per-foot rate of any band below $3M, on a 13-sale sample.

For buyers

Eighty-five percent of closings landed below $1.5 million. The sub-$1M band — 92 transactions — carried a $541 median per-square-foot rate, and the $1M–$1.5M band's 43 closings ran at $535/sq ft, a rate that is slightly lower despite the higher price tier. List prices are not available in this source, so the relationship between asking and closing figures cannot be assessed from this record.

For owners not transacting

The quarter generated $176.1 million in recorded volume across 158 arms-length closings. The per-square-foot median held in a narrow band — $541 to $686 — across the four busiest price tiers (covering 148 of 158 closings). The $3M–$5M tier's $924/sq ft on three sales sits well above that range but rests on too few transactions to treat as a trend line. The quarter's data establishes what the closing record showed; what it implies for unsold properties in any given pocket is a question this record cannot answer.
