Home / Colorado / Boulder County / Superior
So we compared 393 home sales in Superior since July 2024 with the values those homes carry now. The typical home sold for 1.4 percent below its value, and 57 percent sold for less. Your 2027 notice should show up around May 1, 2027, and you'll have until June 8 to protest.
Now that's more than the share across Boulder County as a whole, where 53 percent sold below their value. So honestly, Superior values look pretty close to the market, and for a lot of homes the 2027 number probably won't move much.
But with 57 percent of homes selling below their value, the county's number's probably too high on some homes here, and that's where a protest can really work. Our free check'll compare your new value with genuinely similar homes nearby once the notices are out in May 2027, and tell you straight which side you're on. Most people who use it get told not to bother, and that's kind of the point.
So here's how it works. Your notice of value should arrive around May 1, 2027, and you'll protest to the Boulder County Assessor by June 8. It's free, and it's pretty quick to do. The assessor's got to answer by the last working day of June, and if you still don't agree, you can appeal to the County Board of Equalization by July 15, which doesn't cost anything either.
Now the question in a Colorado protest is what your home was worth on June 30, 2026. So the evidence that really counts is sales of genuinely similar homes nearby from the two years before that date, and what homes sell for later doesn't help much. You don't need a lawyer for any of it, honestly.
And there's more on the whole county in our Boulder County page.
Just so you know, the sales comparison's our own, read from Boulder County's public parcel records on 2026-10-08. Boulder doesn't mark which sales were ordinary sales between strangers, so we've counted warranty and special warranty deed sales since July 1, 2024 for $50,000 or more, one home per recorded deed, for houses and condos built before 2024, and compared each price with the home's current value, which is basically the market as of June 30, 2024. Quitclaims and other deed types aren't counted, because they're pretty much always transfers within a family rather than real sales, so they don't really tell you what a home's worth. We've also left out the odd sale that's under half or over two and a half times the value. The town's the city in the home's address, so it probably includes some unincorporated homes too, and we only show a town that's got at least 100 sales.
And the protest steps are Colorado law, so they're the same in every county. The tax arithmetic's from House Bill 24B-1001, and the example rates are one Longmont home's own 2025 levies from the county's records.
