What can a landlord charge a Section 8 tenant here?

The FMR is not a cap on what you can ask on the open market. For a Housing Choice Voucher tenant, the local housing authority sets a payment standard, normally between 90% and 110% of the FMR (or of the ZIP-level Small Area FMR where those apply). For a two-bedroom unit in Bonneville County that is typically $1,147 to $1,401 including utilities. You can charge more than the payment standard if the rent passes the housing authority's rent-reasonableness test and, at move-in, the tenant's share stays within 40% of their adjusted monthly income. Ask the housing authority for its current payment standard schedule.

HUD income limits for Bonneville County (FY2026)

Income limits decide who qualifies for Section 8 vouchers, public housing and most HUD-assisted units. The area median family income is $101,100 (FY2025: $103,000, −1.8%). Small figures under each limit show the change from FY2025.

Household size	1 person	2 people	3 people	4 people	5 people	6 people	7 people	8 people
Extremely low income (30%)	$21,250 +6.3%	$24,300 +6.3%	$27,350 +2.6%	$33,000 +2.6%	$38,680 +2.7%	$44,360 +2.8%	$50,040 +2.9%	$55,720 +2.9%
Very low income (50%)	$35,400 +6.1%	$40,450 +6.2%	$45,500 +6.2%	$50,550 +6.2%	$54,600 +6.2%	$58,650 +6.2%	$62,700 +6.2%	$66,750 +6.2%
Low income (80%)	$56,650 +6.2%	$64,750 +6.2%	$72,850 +6.3%	$80,900 +6.2%	$87,400 +6.3%	$93,850 +6.2%	$100,350 +6.2%	$106,800 +6.2%

The 30% limit is HUD's “extremely low income” limit: the higher of 30% of median income or the federal poverty guideline, but never above the 50% limit. That is why it can rise faster than 30% of median for larger households. Tax-credit (LIHTC) properties use separate Multifamily Tax Subsidy Project limits.
