Maryland Housing Policy: Affordability, Zoning, and State Programs

Maryland's housing landscape sits at a peculiar intersection: one of the wealthiest states in the nation by median household income, yet home to some of the most acute affordability pressures on the East Coast. This page covers how the state structures its housing policy framework, how zoning authority is distributed between state and local governments, and what programs the Maryland Department of Housing and Community Development administers to address supply gaps and housing cost burdens. It also maps the boundaries of what state policy can and cannot touch, and where federal programs enter the picture.

Definition and scope

Maryland housing policy refers to the statutory, regulatory, and programmatic architecture through which the state attempts to influence housing supply, affordability, and quality. That architecture has three legs: zoning and land use law, direct financial assistance programs, and building and occupancy standards. Each operates at a different altitude.

Zoning authority in Maryland sits primarily with counties and municipalities — not the state. This is consequential. Maryland's 23 counties and Baltimore City each maintain independent zoning codes, which means a developer proposing affordable housing in Montgomery County faces a regulatory environment that shares almost no procedural DNA with one working in Garrett County. The Maryland Department of Housing and Community Development (DHCD) can influence local decisions through funding conditions and program eligibility requirements, but it cannot override locally enacted zoning ordinances. That distinction matters enormously when interpreting the reach of any state housing initiative.

The state's programmatic scope is anchored in the Maryland Code, Housing and Community Development Article, which authorizes DHCD to administer loan and grant programs, manage the Rental Allowance Program, and allocate Low-Income Housing Tax Credits (LIHTC) — the federal program administered at the state level under Internal Revenue Code §42 — across qualifying developments. DHCD's 2023 Annual Report identifies the agency as having financed more than 5,000 affordable units in that fiscal year through a combination of state bonds and federal credit allocations (DHCD Annual Report, FY2023).

Scope limitations: This page addresses Maryland state-level housing policy only. Federal programs administered independently by the U.S. Department of Housing and Urban Development (HUD) — including Section 8 Housing Choice Vouchers, Community Development Block Grants, and HOME Investment Partnerships — operate under separate federal statutory frameworks and are not governed by state law, though Maryland agencies often serve as grantees. Local zoning decisions made by individual counties fall outside state authority and are covered separately in county-specific pages.

How it works

The structural relationship between state and local government in Maryland housing is best understood through two contrasting models: the charter county model and the code county model.

  1. Charter counties — including Montgomery, Prince George's, Baltimore, and Howard counties — operate under home rule authority granted by the Maryland Constitution, Article XI-A. They adopt and amend zoning law largely independently of the General Assembly.
  2. Code counties — the remaining counties operating under general state law — have somewhat less autonomy but still retain primary zoning authority within their borders.
  3. Baltimore City functions as a charter municipality with its own independent zoning code and permitting infrastructure, including the eBuild digital permitting portal.
  4. State overlay authority exists in limited circumstances: the Chesapeake Bay Critical Area Law (Natural Resources Article, Title 8, Subtitle 18) imposes state-level land use controls within 1,000 feet of tidal waters and tidal wetlands, affecting development density and buffer requirements statewide in those zones.
  5. DHCD funding leverage operates as a soft form of state influence — local jurisdictions that want access to state housing funds must meet program eligibility and affirmatively furthering fair housing requirements established by DHCD under the Maryland Fair Housing Act.

The LIHTC allocation process illustrates how state authority flows in practice. DHCD publishes a Qualified Allocation Plan (QAP) each year that determines how federal tax credits are distributed among competing affordable housing developers. The QAP awards points for proximity to transit, income targeting depth, and developer experience. In 2023, DHCD awarded credits supporting approximately $180 million in affordable housing investment (DHCD LIHTC Program).

For deeper context on how the General Assembly structures DHCD's statutory mandate, the Maryland Government Authority provides detailed coverage of how Maryland's executive agencies interact with legislative oversight — a particularly useful frame for understanding how DHCD's rulemaking authority is bounded and renewed through the budget process.

Common scenarios

Housing policy questions in Maryland tend to cluster around three recurring situations.

Affordability gap in metropolitan fringe counties. Counties like Frederick and Charles have experienced rapid population growth — Frederick County grew by approximately 11.5% between 2010 and 2020 (U.S. Census Bureau, Decennial Census 2020) — but their zoning codes have not always scaled affordable housing production accordingly. DHCD's Community Development Block Grant allocations can fund infrastructure that enables denser affordable development, but only where local zoning permits it.

Rural housing deterioration. On the Eastern Shore, counties including Somerset and Dorchester carry significant stocks of aging housing with deferred maintenance. DHCD administers the Maryland Mortgage Program and the Maryland HomeCredit mortgage tax credit, both of which operate statewide but see concentrated uptake in rural markets where conventional financing is harder to secure.

Displacement pressure in urban neighborhoods. In Baltimore City and the inner suburbs of Prince George's County, rising market-rate rents in transit-adjacent areas have created displacement risk for long-term low-income residents. The Maryland Department of Housing page covers DHCD's structure and programs in more detail for readers researching agency-level specifics.

Decision boundaries

Understanding what Maryland's housing policy system covers — and what it cannot — prevents a common interpretive error: assuming that a state program creates state-level rights that override local decisions.

State housing programs do not confer a right to be housed in a specific jurisdiction. A household approved for a Housing Choice Voucher administered by a local Housing Authority is still subject to that Housing Authority's payment standards and landlord participation rates, neither of which the state sets.

The General Assembly can pass legislation encouraging or mandating certain local zoning practices — and has done so in limited ways, including 2022's HB 18, which required local jurisdictions to permit accessory dwelling units (ADUs) in single-family zones as a matter of state law — but enforcement mechanisms remain primarily civil and financial rather than regulatory override.

Fair housing law in Maryland provides one of the clearest examples of a decision boundary. The Maryland Fair Housing Act (Real Property Article, §§ 20-701 through 20-705) prohibits discrimination in the sale, rental, and financing of housing on the basis of race, color, religion, sex, familial status, national origin, disability, marital status, and source of income. The Maryland Commission on Civil Rights enforces these provisions statewide — including against local government actors — making this one area where state law does effectively override local discretion.
