Healdsburg's ZIP code and its neighbors
Healdsburg uses a single residential ZIP code, 95448. It is larger than the city: the Census Bureau's 2020-2024 survey counts 16,077 people and 7,716 homes in ZIP 95448, against 11,243 people and 5,138 homes inside the city limits. The extra territory is land outside the city limits, which is why ZIP figures and city figures for Healdsburg never quite match.
The table compares 95448 with three neighboring Sonoma County ZIPs on one measure, Redfin's median sale price for the three months to September 2026.
| ZIP | Place | Redfin median sale price | Change in a year | Homes sold | Median days on market |
|---|---|---|---|---|---|
| 95448 | Healdsburg | $1,149,662 | +15.0% | 52 | 63 |
| 95492 | Windsor | $814,761 | +0.6% | 58 | 50 |
| 95441 | Geyserville | $1,279,624 | +20.1% | 5 | 131 |
| 95425 | Cloverdale | $589,827 | +2.6% | 28 | 51 |
Redfin's ZIP figures are rolling three-month medians. Geyserville's five sales are too few to read as a trend.

What to check here: whether an address is inside the city limits, which decides city utilities and city services, the fire hazard severity zone, and which school district serves the parcel. Our Healdsburg homes for sale guide covers those checks.
ZIP 95492: Windsor
Windsor is where our featured Healdsburg team keeps its second office, and its ZIP makes a useful price comparison. Zillow's typical home value for 95492 was $795,695 in September 2026, up 1.3%. Redfin's three-month median was $814,761 from 58 sales, with 2.8 months of supply, a much tighter market than Healdsburg's.

ZIP 95441: Geyserville
Geyserville is a small ZIP by sales count. Redfin recorded only five sales in the three months to September 2026, at a median of $1,279,624, and a median of 131 days on market, with 14 homes for sale. With so few sales, one large property can set the median. For any home outside a city water system, ask for well and septic records, and check the fire hazard zone before you price an offer. CAL FIRE places the start of the 2019 Kincade Fire northeast of Geyserville.
ZIP 95425: Cloverdale
Cloverdale is the lowest-priced of these four ZIPs. Redfin's three-month median was $589,827 from 28 sales, up 2.6%, with 51 median days on market. The Census Bureau puts the ZIP's median household income at $119,092 and the median owner-estimated home value at $653,200. For buyers priced out of 95448, it is the lowest-priced of these neighbors; compare commute times and insurance quotes before you choose it.

How to use Healdsburg ZIP data
Match the measure to the question
Use Redfin's median sale price to see what actually sold in the last three months, and Zillow's typical value to see the estimated value of a middle-priced home. Never compare a Redfin figure for one ZIP with a Zillow figure for another.
Read small ZIPs as a range
A ZIP with fewer than 20 sales in three months, such as 95441, can swing by hundreds of thousands of dollars from one period to the next. Look at the longer history on the 95448 data page and ask an agent for the actual sold comparables.
Property taxes follow the tax rate area, not the ZIP. Two homes in 95448 can carry different bond and special tax charges; our Sonoma County property tax guide explains how to find the rate for a parcel.
