The Community Development Block Grant program is a federal formula grant, run by the Department of Housing and Urban Development, that sends money to local governments for housing rehabilitation, public infrastructure, economic development, and services that primarily benefit lower-income residents. Congress created it through the Housing and Community Development Act of 1974, folding several older aid programs into a single flexible grant. Larger cities and urban counties receive their funds directly from HUD; smaller communities apply through their state.
Who Receives CDBG Funds
Funding moves through two tracks, and which track applies depends on the size and classification of the community.
Entitlement Communities
Larger jurisdictions, called entitlement communities, get annual grants directly from HUD on a formula basis. Federal law defines these as the central cities of metropolitan statistical areas and any other city in a metro area with at least 50,000 residents.1Office of the Law Revision Counsel. 42 USC 5302 – General Provisions Urban counties with at least 200,000 residents (not counting the population of entitlement cities inside their borders) also qualify. Once a city earns entitlement status, it generally keeps it even if population later dips below the threshold, though its funding adjusts downward over time.
Non-Entitlement Areas
Smaller cities, towns, and rural areas apply through their state instead of dealing with HUD directly. Each state gets its own CDBG allocation to distribute, either competitively or through a state-designed formula, and sets its own priorities, timelines, and reporting rules within the federal framework. Application windows vary; they are typically announced by each state’s housing or community development agency.
How HUD Calculates Each Grant
HUD runs two formulas for every entitlement community and awards whichever produces the larger amount.2HUD Exchange. CDBG Entitlement Program Eligibility Requirements
The first formula weighs population, poverty (counted twice), and housing overcrowding. The second weighs population growth lag against other metro areas, poverty (counted one and a half times), and age of housing stock (counted two and a half times).3Office of the Law Revision Counsel. 42 USC 5306 – Allocation and Distribution of Funds Because both formulas lean hard on poverty, and the second on housing age, older cities with concentrated poverty tend to draw proportionally larger grants than newer, wealthier ones of similar size.
The Three National Objectives
Every CDBG-funded activity (except general administration and planning) must meet at least one of three national objectives. A project that fails this test can force the grantee to repay funds to HUD.4HUD Exchange. Basically CDBG Chapter 3 – National Objectives
- Benefit to low- and moderate-income persons. The activity must primarily serve households earning up to 80 percent of area median income. For area-wide projects such as street improvements, the service area generally qualifies when at least 51 percent of residents are low- or moderate-income.5HUD Exchange. ACS 5-Year 2016-2020 Low- and Moderate-Income Summary Data
- Prevention or elimination of slums or blight, either in a formally designated area or on a spot basis for a specific blighted property.
- Urgent need, meaning a serious and immediate threat to health or safety, such as disaster recovery, that the locality cannot address with other available resources.
The first objective drives most CDBG spending. At least 70 percent of a grantee’s CDBG funds, measured over a one- to three-year period the grantee selects, must go to activities that benefit low- and moderate-income persons.6eCFR. 24 CFR 570.484 – Overall Benefit to Low and Moderate Income Persons The remaining 30 percent can address blight or urgent needs. Weak beneficiary-income documentation is a common audit problem: HUD may reclassify a project as failing to meet a national objective even when the intent was clearly to help lower-income residents.
What CDBG Money Can Pay For
Eligible activities are broad by design. Common categories include property acquisition for public use or redevelopment; construction or improvement of streets, sidewalks, water and sewer lines, and community facilities; housing rehabilitation for privately owned homes and public housing units; economic development loans or grants to businesses that create or retain jobs for lower-income workers; public services such as job training, childcare, and health programs; and removal of architectural barriers to make buildings accessible to people with disabilities.7eCFR. 24 CFR 570.201 – Basic Eligible Activities
Public services carry a hard cap: spending on them cannot exceed 15 percent of the grant amount, plus 15 percent of any program income for entitlement communities. Two service-oriented projects, such as an after-school program and a health clinic, can consume most of that allowance on their own.
What CDBG Money Cannot Pay For
Several categories are off-limits by regulation.8eCFR. 24 CFR 570.207 – Ineligible Activities
- Buildings used for the general conduct of government, such as city halls, county offices, and courthouses. Accessibility improvements to those buildings are the one exception.
- Routine operating costs of local government.
- Political activities, including voter registration drives and partisan events. A CDBG-funded community center can host political events incidentally, but only if all parties get equal access and pay the same fees.
- Most purchases of construction equipment, motor vehicles, and furnishings, though leasing costs and depreciation tied to otherwise eligible activities are allowed.
- Direct income payments to individuals or households. Subsistence-type assistance is eligible only when the payment goes to a third party such as a landlord or utility.
Planning and Citizen Participation
Before any CDBG dollar moves, the grantee has to produce a set of interlocking planning documents. HUD rejects applications with weak or incomplete plans.
Each grantee adopts a citizen participation plan describing how residents will be involved in spending decisions. Federal rules require at least two public hearings per year at different points in the program cycle, held at times and places accessible to the people the program serves, with at least one hearing before the draft plan is published. Grantees must also provide a 30-day public comment period on the consolidated plan and a 15-day comment period on annual performance reports.9eCFR. 24 CFR 91.105 – Citizen Participation Plan; Local Governments
The consolidated plan is a three- to five-year strategy identifying housing and development needs, priorities, and resources. It draws on census data, housing market analyses, and the citizen participation process. Each year within that period, the grantee also files an annual action plan setting out specific projects and dollar amounts, along with low- and moderate-income area maps by census tract.
Entitlement communities submit these plans through the IDIS eCon Planning Suite, a module inside HUD’s Integrated Disbursement and Information System. HUD then has 45 calendar days to review; if no disapproval issues in that window, the plan is deemed approved.10U.S. Department of Housing and Urban Development. CPD-26-05 An authorized local official then signs a grant agreement.
Environmental Review Before Any Spending
Signing the grant agreement does not free the money. No CDBG funds can be committed and no physical work can begin until an environmental review is complete and HUD (or the state, for non-entitlement grants) issues a formal Release of Funds. The local government itself serves as the “responsible entity” that carries out the review.11eCFR. 24 CFR Part 58 – Environmental Review Procedures for Entities Assuming HUD Environmental Responsibilities
The responsible entity maintains a written Environmental Review Record for each project, documenting compliance with the National Environmental Policy Act and related federal laws. Related activities on the same site or serving the same geographic area must be grouped and evaluated as a single project, not sliced into smaller pieces to ease the review. Committing funds or breaking ground before the Release of Funds can force the grantee to repay the entire project cost from local money.
Davis-Bacon Wages on Construction Work
When CDBG funds pay for construction, the Davis-Bacon Act’s prevailing wage requirements typically apply. Workers on covered projects must be paid at least the locally prevailing wage rate for their trade, as set by the Department of Labor. For residential work, Davis-Bacon applies only when the property has eight or more units. Single-family and small residential buildings with seven or fewer units are exempt.12HUD Exchange. When Do Davis-Bacon Requirements Apply to Construction on Residential Property
How HUD counts “property” matters. All buildings on an undivided lot, or on contiguous lots under common ownership and operation, count together. Five side-by-side townhouses with two units each add up to a ten-unit property, triggering Davis-Bacon even though no single building has eight units. Scattered-site single-family rehab programs are generally clear of the requirement; multi-family and rental rehab projects need careful unit counting before construction starts.
Program Income Rules
Revenue from CDBG-funded activities — loan repayments, property sales, rental income, interest earned — is classified as “program income” and stays subject to CDBG rules. Retained program income must be spent on eligible activities that meet a national objective, and it must be spent before the grantee draws new funds from the Treasury.13Government Publishing Office. 24 CFR 570.504 – Program Income
At the end of each program year, any program income cash balance above one-twelfth of the most recent grant amount must be remitted to HUD for redeposit into the grantee’s line of credit. Even after a grant closes out, income from disposed property or outstanding loans has to keep serving CDBG-eligible purposes if the grantee has another active CDBG grant.
The Timeliness Test on Unspent Funds
HUD tracks how fast grantees spend, not just how they spend. Sixty days before the end of each program year, HUD checks the grantee’s unspent balance in its U.S. Treasury account. If that balance is more than 1.5 times the current-year grant, the grantee is failing the timeliness test.14eCFR. 24 CFR 570.902 – Review to Determine if CDBG-Funded Activities Are Being Carried Out in a Timely Manner
Consequences can include corrective action, reduced future grants, or loss of entitlement status. Penalties are avoidable only when the delay was truly outside the grantee’s control. Slow procurement, staff turnover, and poor project management do not qualify as excuses. This is why experienced grantees keep a pipeline of shovel-ready projects lined up before the grant year begins.
Records, Audits, and the Annual Performance Report
Grantees must keep all financial and program records for four years from the date they execute the grant closeout agreement. That includes documentation showing how each activity met a national objective, beneficiary income data, procurement files, and environmental reviews.15eCFR. 24 CFR 570.502 – Applicability of Uniform Administrative Requirements Because the clock starts at closeout rather than at the end of the program year, records tied to a multi-year project can end up being kept for a decade or longer from the date the activity first began.
Any local government or nonprofit that spends $1,000,000 or more in total federal awards in a fiscal year must undergo a single audit covering all its federal programs, CDBG included.16eCFR. 2 CFR 200.501 – Audit Requirements Most entitlement communities cross that threshold easily. The audit tests whether funds went to eligible activities, whether national objectives were met, whether financial controls hold up, and whether the grantee complied with cross-cutting federal requirements on civil rights and environmental review.
Each year, the grantee prepares a Consolidated Annual Performance and Evaluation Report, or CAPER, documenting the prior year’s accomplishments: people and households served, jobs created or retained, housing units completed, and funds expended by activity. The public gets at least 15 days to review and comment before the CAPER goes to HUD.9eCFR. 24 CFR 91.105 – Citizen Participation Plan; Local Governments HUD reads the CAPER as its main performance signal, and weak reporting is often the first warning that a formal monitoring visit is coming.
