Must city councils personally consider Banberry factors when setting impact fees? Home Builders Association v. American Fork Explained

The Utah Supreme Court’s decision in Home Builders Association of Utah v. City of American Fork clarifies an important misconception about municipal impact fee requirements under the landmark Banberry decision. The case demonstrates that procedural compliance with analytical frameworks differs significantly from substantive legal standards.

Background and Facts
American Fork City enacted ordinances establishing sewer and water connection fees for new developments. When deposing city council members who voted on these fees, Home Builders Association discovered that the council members could not personally recall considering the seven Banberry factors during their deliberations. Home Builders argued this failure rendered the fees void ab initio, and the district court agreed, granting summary judgment.

Key Legal Issues
The central question was whether municipal impact fees are automatically invalid if city council members cannot demonstrate personal consideration of the Banberry factors during the fee-setting process. Home Builders contended that council members had an affirmative duty to apply these factors directly, while American Fork argued that staff analysis supporting the fees was sufficient.

Court’s Analysis and Holding
The Utah Supreme Court reversed, holding that the Banberry factors are “an illustrative list of factors that municipalities should consider” rather than mandatory requirements. The Court emphasized that the ultimate legal standard is whether fees require newly developed properties to bear no more than their equitable share of capital costs. The Banberry factors are means to that end, not the end itself. The Court rejected the notion that council members must personally conduct detailed factual analysis, noting that staff personnel appropriately perform such tasks.

Practice Implications
This decision reinforces that summary judgment is rarely appropriate in impact fee challenges due to their highly fact-dependent nature. Practitioners should focus on the substantive reasonableness of fees rather than procedural compliance with analytical frameworks. The decision also confirms that municipalities retain flexibility in fee-setting methodologies, provided the ultimate equitable share standard is met.
