The poverty line in San Diego is $33,000 a year for a family of four under the 2026 federal poverty guidelines, the same figure used across the 48 contiguous states. That national number ignores what it actually costs to live here, so San Diego County and California use a separate set of income limits tied to the local area median income of $130,800. Those local thresholds, which reach $132,400 for a low-income family of four, are what most housing, food, healthcare, and utility programs actually use to decide who qualifies.
2026 Federal Poverty Guidelines
The Department of Health and Human Services publishes updated poverty guidelines each January, adjusted for the previous year’s rise in consumer prices.1Federal Register. Annual Update of the HHS Poverty Guidelines The same figures apply across the 48 contiguous states and the District of Columbia; Alaska and Hawaii have their own, higher numbers. For 2026, the contiguous-state guidelines are:2U.S. Department of Health and Human Services. 2026 Poverty Guidelines
- 1 person: $15,960
- 2 people: $21,640
- 3 people: $27,320
- 4 people: $33,000
- 5 people: $38,680
- 6 people: $44,360
- 7 people: $50,040
- 8 people: $55,720
- Each additional person: add $5,680
These baseline numbers matter because program eligibility is almost always written as a percentage of them. A family of four earning $33,000 is at 100 percent of the federal poverty level. The same family earning $45,540 is at 138 percent, the cutoff for adult Medi-Cal coverage.
Why the Federal Number Understates Poverty in San Diego
The federal guidelines use one national formula and make no adjustment for regional costs. A four-person household at $33,000 a year has about $2,750 a month to cover rent, utilities, food, transportation, childcare, and everything else combined. Median rent for a two-bedroom apartment in San Diego routinely runs over $2,000. On the federal number alone, you qualify as poor only when you are already in acute financial crisis, and many San Diego households earning well above $33,000 still cannot cover basic needs. That is why local assistance programs rely on the area median income system instead.
San Diego’s Local Income Limits
The U.S. Department of Housing and Urban Development calculates an area median income for the San Diego-Carlsbad Metropolitan Statistical Area each year. The current AMI for San Diego County is $130,800 — the midpoint of all household incomes in the county.3SanDiegoCounty.gov. Area Median Income (AMI) and Income Limits California law then slices that figure into tiers based on percentage of AMI, adjusted for household size. The current San Diego County limits are below.
Extremely Low Income (30 Percent of AMI)
Households at this tier face the most severe cost burdens and get the highest priority for subsidized housing.
- 1 person: $34,750
- 2 people: $39,700
- 3 people: $44,650
- 4 people: $49,600
- 5 people: $53,600
- 6 people: $57,550
- 7 people: $61,550
- 8 people: $65,500
Very Low Income (50 Percent of AMI)
This is the standard cutoff for Section 8 Housing Choice Voucher eligibility.
- 1 person: $57,900
- 2 people: $66,150
- 3 people: $74,450
- 4 people: $82,700
- 5 people: $89,350
- 6 people: $95,950
- 7 people: $102,550
- 8 people: $109,200
Low Income (80 Percent of AMI)
Households at this level qualify for many rent-restricted apartment communities and local homebuyer assistance programs.
- 1 person: $92,700
- 2 people: $105,950
- 3 people: $119,200
- 4 people: $132,400
- 5 people: $143,000
- 6 people: $153,600
- 7 people: $164,200
- 8 people: $174,800
Notice what the $132,400 figure says about San Diego: a family of four earning more than four times the federal poverty line still counts as low income for housing purposes here.
Moderate Income (120 Percent of AMI)
The moderate income tier is used mostly for inclusionary housing and certain homeownership assistance. A single individual limit is $109,850, a four-person household is $156,950, and an eight-person household can earn up to $207,150.4Department of Housing and Community Development. 2025 State Income Limits
Which Programs Use Which Numbers
The threshold that matters depends on the benefit you are looking at. Housing programs run on AMI; health and food programs run on the federal poverty level.
Medi-Cal
California’s Medicaid program covers adults ages 19 through 64 with household income at or below 138 percent of the federal poverty level. For children 18 and under, the cutoff rises to 266 percent. In 2026 that works out to roughly $22,025 a year for a single adult and about $45,540 for a family of four, with coverage for children in that same four-person household reaching to about $87,780.2U.S. Department of Health and Human Services. 2026 Poverty Guidelines
CalFresh (SNAP)
Federal SNAP rules set a gross income limit of 130 percent of the poverty level, but California uses broad-based categorical eligibility to raise that to 200 percent.5Food and Nutrition Service. SNAP Eligibility For a family of four, gross monthly income up to about $5,360 (roughly $64,320 a year) can still make you eligible to apply. You also have to pass a net income test of $2,680 a month after allowable deductions for housing, dependent care, and medical expenses for elderly or disabled household members.
Section 8 Housing Choice Vouchers
The San Diego Housing Commission runs the voucher program locally. General eligibility sits at the very low income tier (50 percent of AMI), but federal rules require that at least 75 percent of newly issued vouchers go to extremely low income households at 30 percent of AMI.6HUD USER. Income Limits For a family of four in San Diego, that means income below $49,600 for the top-priority tier or below $82,700 for the broader eligibility pool.3SanDiegoCounty.gov.

LIHEAP (Utility Assistance)
The Low Income Home Energy Assistance Program helps qualifying households pay heating and cooling bills. California’s 2026 monthly income limits are $3,332 for a single person and $6,407 for a family of four — roughly $39,984 and $76,884 a year.7California Department of Community Services and Development.

What San Diego Actually Costs to Live In
The thresholds above decide who qualifies for help. They do not describe what it costs to get by here without any. The Self-Sufficiency Standard, developed by the Center for Women’s Welfare at the University of Washington, tries to answer that second question by pricing out housing, childcare, food, transportation, healthcare, taxes, and a small buffer for miscellaneous needs.8County of San Diego. Self-Sufficiency Wage
By that measure, a single adult in San Diego County needed around $38,919 a year as of the most recent calculation — more than double the federal poverty line for one person.9County of San Diego, Health and Human Services Agency. San Diego County Self-Sufficiency Standard Brief A single parent with young children needs substantially more, since childcare alone can exceed $12,000 per year per child in the county. Plenty of households earn too much to qualify for CalFresh or adult Medi-Cal yet still fall short of covering real local costs.
Tax Credits That Reach Higher Up the Income Scale
Even households that do not qualify for direct assistance can see significant money through two federal tax credits.
The Earned Income Tax Credit is refundable, which means you can receive it even if you owe no federal income tax. For the 2025 tax year, maximum adjusted gross income for a single filer runs from $19,104 with no children up to $61,555 with three or more children. Married couples filing jointly have higher limits, reaching $68,675 with three or more children. Investment income must stay at $11,950 or less.10Internal Revenue Service. Earned Income and Earned Income Tax Credit (EITC) Tables Given local wages and costs, many working San Diego families earning well above the federal poverty line still qualify.
The Child Tax Credit for the 2025 tax year is up to $2,000 per qualifying child under age 17. It begins to phase out at $200,000 of income for single and head-of-household filers and $400,000 for married couples filing jointly, at a rate of 5 percent of income above those thresholds. Most San Diego families with children and income under $200,000 receive the full amount.
