Rent Affordability in Berkeley 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
$831/mo
Based on $33,250 annual income
50% AMI
$1,386/mo
Based on $55,450 annual income
80% AMI
$2,218/mo
Based on $88,700 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 Berkeley County, a family of four earning exactly at 50% AMI ($55,450) should aim to keep total housing costs below $1,386 per month to avoid cost burden.

What These Numbers Mean For You
In Berkeley County, the 2025 Area Median Income of $110,900 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 $88,700 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 ($55,450) can afford roughly $1,386/month under the 30% rule — whether that covers available units in Berkeley County depends on local rental market conditions.
For buyers and developers, the higher AMI supports stronger underwriting. LIHTC projects in Berkeley County can set maximum rents based on the 60% AMI threshold ($66,550 for a 4-person household), which in a higher-AMI market translates to more financially viable affordable housing developments.
