Summit County is a high-AMI market — the local median income of $168,600 exceeds both the Utah statewide figure of $116,100 and the national median of $96,300 by a significant margin. In practical terms, this means income limits for affordable housing programs are set higher here, so households earning moderate incomes in many other markets might still qualify for subsidized housing in Summit County. Developers evaluating LIHTC projects in this area can underwrite higher rents while remaining within compliance thresholds.
Rent Affordability in Summit County
Using the standard 30% rule — a household should spend no more than 30% of gross income on housing — here's the maximum affordable monthly rent at each AMI tier for a 4-person household.
30% AMI
$1,250/mo
Based on $50,000 annual income
50% AMI
$2,084/mo
Based on $83,350 annual income
80% AMI
$2,605/mo
Based on $104,200 annual income
The 30% Rule:HUD defines a household as "cost-burdened" when it spends more than 30% of gross income on housing costs (rent plus utilities). Households exceeding 50% are considered "severely cost-burdened." In Summit County, a family of four earning exactly at 50% AMI ($83,350) should aim to keep total housing costs below $2,084 per month to avoid cost burden.

What These Numbers Mean For You
In Summit County, the 2025 Area Median Income of $168,600 places this area above the national benchmark. Because AMI thresholds are set locally, residents here face higher income limits for program qualification — a household earning $104,200 qualifies as Low Income (80% AMI), while the same income in a lower-cost market would likely exceed the cutoff.
For renters, this creates a dual reality: the income limits are more generous, but market rents are typically higher too. A family at exactly 50% AMI ($83,350) can afford roughly $2,084/month under the 30% rule — whether that covers available units in Summit County depends on local rental market conditions.
For buyers and developers, the higher AMI supports stronger underwriting. LIHTC projects in Summit County can set maximum rents based on the 60% AMI threshold ($101,150 for a 4-person household), which in a higher-AMI market translates to more financially viable affordable housing developments.
