“Has the effect of prohibiting”

The municipal text does not stop at rules that say no. It reaches a regulation that “has the effect of prohibiting” removal — language Utah uses elsewhere in association law, including § 57-8a-231(2), which bars a governing document that “prohibits, or has the effect of prohibiting, a lot owner of a detached dwelling from incorporating water wise landscaping.”

That phrasing is what reaches an approval process rather than a ban. A design-review requirement that never produces a decision, or a screening covenant that cannot be satisfied without the vegetation staying, operates as a prohibition whatever the document calls it.

Which properties are “designated”

The designation is not the association's to make and not the city's either. Under House Bill 48 of the 2025 session, effective January 1, 2026, the Utah Division of Forestry, Fire and State Lands maintains a statewide wildland-urban interface risk map built on a structure exposure score, and local governments develop their own maps from it.³ The same law attached an annual per-structure fee, $20 to $100 for 2026–27 based on square footage, collected through the county property tax bill, with a triage assessment of vegetation and building materials folding into the figure from 2028.

Utah's Wasatch Back is expected to be classified WUI more or less in its entirety, which puts Park City, Summit County and the Wasatch foothills communities squarely inside the new rule — alongside the Washington County communities around St. George.⁴

The friction this resolves, and the friction it creates

Architectural and landscaping covenants in Utah's foothill and resort communities commonly require mature screening vegetation, minimum plantings, or preservation of existing trees. The defensible-space requirements of the wildland-urban interface code run the other direction: clearance zones around a structure, thinning, removal of ladder fuels. Where a property is inside a designated area, the statute now decides which instruction wins.

What it does not do is settle who pays for the consequences. An owner who clears to code and an association whose covenant assumed the screening would remain are looking at the same yard with different obligations, and the bill says nothing about restoration, replacement planting or the maintenance responsibility that follows. Our Utah architectural review page covers the procedural side — how a board adopts or changes a design criterion under § 57-8a-217, and the 60-day owner disapproval window that attaches to it.

Where it sits in the water-wise scheme

Putting the wildfire clause inside § 57-8a-218(15) is not accidental. That subsection already requires an association to adopt rules supporting water-wise landscaping, and already bars a rule that would “prohibit or restrict the conversion of a grass park strip to water wise landscaping…[or] prohibit low water use on lawns during drought conditions.” Utah has been steadily converting association landscaping authority from a general power into a list of things it may not reach. Our Utah water conservation page sets out the whole scheme, including the separate standalone section at § 57-8a-231 and its $500-or-actual-damages remedy.

What to watch next

The insurance half of the same problem is moving on its own timetable. The Utah Insurance Department's rule R590-291, on the use of fire hazard data in rating and underwriting, took effect July 1, 2026 after a delay from January, and requires an insurer writing in a designated high-risk WUI area to justify its use of fire hazard data other than the state's own mapping tool.⁵ The Business and Labor Interim Committee has wildfire-driven insurance costs on its 2026 study list ahead of the 2027 session.
