Cities and counties working on affordable housing don’t write checks directly to struggling families and call it a day. The reality of municipal housing assistance is considerably more complex โ and more interesting. Local governments operate simultaneously on two fronts: the demand side, helping individual households afford housing that already exists, and the supply side, creating or preserving the affordable units those households need in the first place. Understanding the distinction between these two fronts, and the specific tools deployed on each, is essential for any honest evaluation of whether a city’s housing strategy is actually working.
What follows is a plain-language guide to the most common tools in the municipal housing toolkit, organized by function, with an explanation of what each tool does and where the money originates.
Demand-Side Tools
These tools help households afford housing by subsidizing the cost of renting or owning, rather than directly creating new units.
HCV โ Housing Choice Voucher Program Commonly called Section 8, this is the largest federal rental assistance program in the country. An eligible low-income household receives a voucher that covers the difference between 30% of their income and the fair market rent for their area. The household finds a private landlord willing to accept the voucher, and the local housing authority pays the landlord the subsidy directly. The program is funded entirely by the federal Department of Housing and Urban Development (HUD) and administered locally by a public housing authority โ in Plymouth’s case, the HRA. The city’s role is administration; the money originates in Washington. The primary constraint is not eligibility but supply: waiting lists of hundreds or thousands of applicants are common because the number of vouchers is fixed by congressional appropriation.
DPA โ Down Payment Assistance Homeownership is out of reach for many moderate-income households not because they cannot afford a monthly mortgage payment but because they cannot accumulate the lump sum needed for a down payment and closing costs in a high-price market. Down payment assistance programs provide grants or deferred loans โ often forgiven after a period of occupancy โ to bridge that gap. Funding typically comes from CDBG allocations, state housing finance agency programs, or local HRA levies. Plymouth’s program currently offers up to $35,000, which against a median sale price of $616,000 covers roughly 5.7% โ meaningful but increasingly strained by price appreciation.
LAHA โ Local Affordable Housing Aid A relatively new Minnesota-specific tool, LAHA is an annual appropriation distributed to eligible cities and counties from a regional sales tax collected across the seven-county Twin Cities metro area. Payments began in 2024. Unlike federal programs, LAHA dollars come with relatively flexible use rules โ eligible activities include construction, acquisition, rehabilitation, rent assistance, interest rate reduction, and gap financing. The funds must be committed within three years and expended within four. Plymouth had received approximately $1.3 million through early 2026. Because LAHA is locally controlled and flexible, it is one of the more strategically useful tools in Plymouth’s current toolkit.
BITH โ Bring it Home A Minnesota Housing Finance Agency rental assistance program that allocates vouchers to local housing authorities for distribution to income-qualified households within a specific geography โ meaning, unlike portable HCV vouchers, these cannot be used outside the city. Plymouth received 36 vouchers through this program, expected to be operational by spring 2026 at a cost of approximately $535,000 annually. Funding originates with the state of Minnesota through Minnesota Housing. The geographic restriction is both a limitation and a feature: it keeps assisted households in the community rather than allowing the subsidy to follow them elsewhere.
Supply-Side Tools
These tools create, preserve, or rehabilitate affordable housing units โ addressing the stock itself rather than individual households’ ability to pay.
TIF โ Tax Increment Financing TIF is the workhorse of municipal development finance and the tool Plymouth has used most aggressively for affordable housing. When a city creates a TIF district around a development site, it freezes the assessed value of that property at its pre-development baseline. As the development increases the property’s value and generates higher tax revenues, the incremental increase โ the difference between the old and new tax bill โ is captured and redirected to finance the project rather than flowing to the general tax base. This increment can pay off bonds that funded upfront infrastructure or gap financing for the project. TIF money is not an appropriation from a budget โ it is a pledge of future tax revenue. For affordable housing, TIF is typically used to cover the financing gap that makes a project financially viable when rents must be kept below market rate. Plymouth has used TIF to generate over $6.5 million in affordable housing financing across multiple projects. Up to 35% of increments from redevelopment districts can be pooled and used for projects beyond the original district boundaries when applied to qualifying housing.
LIHTC โ Low Income Housing Tax Credit Pronounced “lie-tech,” this is the primary federal tool for financing the construction of affordable rental housing and is responsible for the majority of affordable units built in the United States since its creation in 1986. The federal government allocates tax credits to state housing finance agencies โ in Minnesota, that is Minnesota Housing โ which then award credits competitively to developers. A developer who receives a LIHTC award sells the credits to investors (typically banks and corporations seeking to reduce their federal tax liability) in exchange for equity capital. That equity reduces the amount the developer needs to borrow, which in turn allows rents to be set below market rate while the project remains financially viable. Units financed with LIHTC must remain affordable โ typically at 60% AMI or below โ for at least 30 years. The money does not flow from government to developer directly; it flows from the federal treasury to investors through reduced tax liability, and from investors to developers as equity. Plymouth has multiple LIHTC-financed projects in its affordable housing inventory including Element, Cranberry Ridge, and West View Estates.
HRB โ Housing Revenue Bonds Cities and counties can issue tax-exempt bonds to finance residential rental housing. Because the interest earned on these bonds is exempt from federal income tax, investors accept a lower interest rate, which translates into lower borrowing costs for the developer. The savings on debt service allow rents to be set below what a market-rate project financed with conventional taxable debt would require. The city is not on the hook financially โ these are conduit bonds, meaning the city serves as the issuing vehicle but the developer is responsible for repayment. In exchange for the tax-exempt status, developers are typically required to set aside a portion of units at affordable rents. Plymouth has used housing revenue bonds extensively, with 846 rental units across city properties financed this way. The money originates with private bond investors; the federal subsidy is the tax exemption.
CDBG โ Community Development Block Grant CDBG is a federal block grant program administered by HUD that flows to cities and counties for a wide range of community development activities, with housing rehabilitation being one of the most common uses. Unlike categorical grants with narrow use restrictions, CDBG gives localities considerable flexibility in how funds are deployed, subject to the requirement that activities primarily benefit low- and moderate-income persons. Plymouth uses CDBG for its First-Time Homebuyer Program, its Owner-Occupied Housing Rehabilitation Program, its Emergency Repair Grant program for seniors, and funding for social service agencies. The money originates entirely with the federal government. Plymouth receives approximately $250,000 annually plus program income from loan repayments. Importantly, CDBG administration requires significant staff capacity and reporting, which is why Plymouth is considering whether to transfer administration to Hennepin County โ freeing staff time but losing some local control over how the funds are directed.
HIA โ Housing Improvement Area An HIA is a Minnesota-specific statutory tool that allows a city to finance common-area improvements to townhome or condominium developments by levying the cost against the individual property owners in the affected association, collectible through property tax statements over time. It functions like a special assessment but for private common property rather than public infrastructure. The tool is particularly useful for older attached housing developments where the homeowners association lacks the reserves or borrowing capacity to fund major capital repairs โ roof replacements, siding, windows, elevators โ that if deferred would accelerate deterioration and reduce the affordability and habitability of the units. Plymouth adopted an HIA policy in early 2026. No public money is permanently expended โ the city essentially extends its credit and taxing authority to enable a private association to finance improvements, recovering the cost through the levy. This makes it a powerful preservation tool with relatively low fiscal risk.
4d โ Local 4d Affordable Housing Incentive Program The name comes from Minnesota Statute 273.128, which establishes a reduced property tax classification rate for rental housing where at least 20% of units are income and rent restricted at or below 60% of AMI. The reduced rate โ from 1.25% to 0.75% of assessed value โ lowers the property tax bill for qualifying landlords, improving the project’s operating economics and making it more feasible to maintain affordable rents. A city or HRA triggers eligibility by providing nominal financial assistance and entering a development agreement with the property owner that records the rent restrictions against the deed. Plymouth adopted a local 4d incentive program in early 2026. The money for the tax reduction does not come from the city budget directly โ it comes from the tax base, meaning other taxpayers effectively subsidize the reduced rate for qualifying properties. The tool is most valuable for preserving NOAH properties that are already charging affordable rents but might escalate without an incentive to maintain restrictions.
IHP โ Inclusionary Housing Policy An inclusionary housing policy requires or incentivizes developers of new market-rate housing to include a percentage of units affordable to lower-income households as a condition of receiving city financial assistance or land use approvals. The mechanism varies โ some policies mandate inclusion, others offer density bonuses or fee waivers in exchange for voluntary compliance. Plymouth adopted an IHP in 2024 that applies to projects receiving city financial assistance, requiring developers to choose a level of affordability appropriate to their project. Affordable units produced under an IHP are financed by the market-rate portion of the development โ in effect, market-rate tenants cross-subsidize affordable tenants through the blended economics of the project. No direct public dollars fund the affordable units, though the city’s financial assistance (often TIF) is what triggers the requirement. The tool only works in markets where development is actively occurring and margins are sufficient to absorb the cross-subsidy.
HTF โ Housing Trust Fund A housing trust fund is a dedicated pool of public money that can be deployed flexibly to fill financing gaps in affordable housing projects that cannot be fully financed through other sources. Unlike categorical programs with rigid use restrictions, an HTF can provide grants, loans, or equity contributions depending on what a specific project needs. Funding can come from a variety of sources โ developer fees, bond proceeds, general fund appropriations, fines and penalties, or dedicated tax revenues. Plymouth established its Housing Trust Fund in 2025 with an initial HRA allocation of $100,000 โ a meaningful first step but a very small pool relative to the financing gaps in typical affordable housing projects, which commonly run into the millions. The value of an HTF grows over time as loan repayments recycle back into the fund and as additional revenue sources are dedicated to it. Cities with mature housing trust funds โ Minneapolis being the clearest regional example โ use them as the primary local matching tool for LIHTC applications and other competitive state and federal programs.
NOAH Preservation Programs โ Naturally Occurring Affordable Housing Preservation NOAH properties are privately owned rental buildings that charge rents affordable to lower-income households not because of any subsidy or restriction but because they are older, smaller, or less amenity-rich than newer buildings. They represent the largest source of unsubsidized affordable housing in most cities and are also the most fragile โ when they sell, rents typically increase to market rate and the affordability is permanently lost. NOAH preservation programs use a combination of acquisition financing, rehabilitation loans, and affordability covenants to intercept these properties before or at sale and lock in affordability for an extended period. Funding comes from a patchwork of sources: LAHA, pooled TIF, HTF, state programs through Minnesota Housing, and federal programs including the HOME Investment Partnerships Program. Plymouth’s 4d program, HIA policy, and LAHA funds are all oriented in part toward NOAH preservation, though a dedicated acquisition fund does not yet exist.
Land Assembly and Disposition Cities and HRAs can use their powers of eminent domain or negotiated purchase to acquire strategic parcels โ often underutilized commercial sites, former motels, or obsolete retail โ and either hold them for future affordable development or sell them at below-market prices to affordable housing developers. The land write-down reduces the developer’s total project cost, which in turn reduces the financing gap and the level of subsidy needed from other sources. Plymouth has used this tool at the Four Seasons Mall site and the former Red Roof Inn on Annapolis Lane. Funding for acquisition comes from HRA levy dollars, LAHA, or pooled TIF. The tool requires patience โ assembling land, conducting environmental review, and finding the right developer and financing package can take years โ but in high-land-cost markets like Plymouth it is one of the most powerful levers for enabling deeply affordable development that the market would never produce on its own.
These tools are rarely used in isolation. A typical affordable housing project in Plymouth might combine LIHTC equity, a city TIF note, an HRB for conduit financing, LAHA gap funding, and an IHP covenant โ each piece filling a specific layer of the financing stack. Understanding what each tool does, where the money comes from, and which household archetypes it ultimately serves is the prerequisite for evaluating whether a city’s housing strategy is coherent, targeted, and producing results commensurate with the public investment behind it.
