Maryland Development Fees
Maryland counties use a layered framework of zoning and planning application fees, Adequate Public Facilities Ordinance (APFO) requirements, school facilities surcharges, transportation impact taxes, and separately-administered water and sewer connection charges. There is no single statewide impact fee statute, so fee research happens county by county and program by program.

How Development Fees Work in Maryland
Maryland is a Dillon Rule state in which counties exercise authority delegated by the General Assembly through state enabling acts and, for charter counties, through their own charters. The legislature has not enacted a statewide impact fee statute comparable to Texas Local Government Code Chapter 395. Instead, several distinct programs operate in parallel, and each county adopts the mix that fits its growth and infrastructure pressures.
The most common Maryland tool is the Adequate Public Facilities Ordinance (APFO): a subdivision and site plan condition that ties development approval to whether schools, roads, water, sewer, and public safety facilities have capacity to serve the new project. Where capacity is constrained, an APFO can require phasing, mitigation payments, or fee-in-lieu contributions, but the structure varies meaningfully by county.
Several Maryland counties also adopt a school facilities surcharge or school construction excise tax on residential building permits to fund new school capacity, and a transportation impact tax on new development to fund roadway capacity. These programs are typically authorized by county council legislation and adopted by ordinance, with rates published in the county code or in a county council resolution. Howard County, Montgomery County, and Prince George's County are among the larger counties that have used some combination of these tools.
Maryland counties also charge zoning, planning, and subdivision application fees from a county Department of Planning and Zoning fee schedule. These are typically adopted as part of the annual county budget effective July 1 and cover staff review of zoning map amendments, comprehensive and text zoning amendments, conditional use applications, variance applications, board of appeals appeals, sign variances, administrative adjustments, plats, and site development plans. They cover the cost of staff review rather than infrastructure capacity.
Finally, water and wastewater service for new development is provided by either the county Department of Public Works (Howard County DPW Bureau of Utilities, for example), an independent regional authority (such as WSSC Water for Montgomery and Prince George's), or a municipal utility department. These utilities charge connection or capacity charges for new service - structurally similar to one-time tap fees in other states - and ongoing volumetric and base service charges for occupied properties. The county planning department's review of subdivision-level water and sewer facilities is a separate administrative review fee that typically lives in the planning fee schedule.

What This Coverage Includes
ZoneFee currently has 3 Maryland jurisdictions live: Howard County (Baltimore-Washington Corridor), Montgomery County (Suburban Maryland / Washington Metro), and Frederick County (I-270 Technology Corridor / Western Maryland). Each record is published under ZoneFee's Partial-Verified Publication Standard, with at least one meaningful development-fee family confirmed verbatim from an official primary source. Howard County covers the DPZ Land Development and Zoning Fees Schedule (FY26 effective July 1, 2025) and the DPZ Water and Sewer Facilities Review Fees Schedule (also FY26). Montgomery County covers the Transportation Impact Tax and School Impact Tax framework (DPS Impact Taxes Handout effective July 1, 2023 to June 30, 2025) and the DPS zoning fee schedule. Frederick County covers the FY26 Development Impact Fee (Public School and Library; Single Family Detached $19,408 total under Article 25 Section 9J of the Annotated Code of Maryland and County Code Section 1-22). Fee families that were not located via official sources on the relevant verification pass are honestly disclosed on each jurisdiction page as unverified rather than estimated. Connection and capacity charges administered by separate utility authorities (Howard County DPW Bureau of Utilities, WSSC Water for Montgomery, and the Frederick County Division of Utilities and Solid Waste Management or the incorporated municipalities) are queued for separate authority records.
Researching Maryland Fees: What to Expect
Looking up Maryland development fees works differently than in single-statute impact-fee states. For each Maryland jurisdiction, expect to consult several separate document types: the county Department of Planning and Zoning fee schedule (for zoning, subdivision, and site plan application fees - usually adopted annually through the budget effective July 1); county council legislation establishing the school facilities surcharge, school construction excise tax, or transportation impact tax (where applicable); the county subdivision and zoning regulations for APFO standards; the FY budget appendix where adopted impact taxes and surcharge rates are commonly republished; and the water and sewer authority's connection charge schedule (county DPW, WSSC, or a regional authority depending on the county). ZoneFee jurisdiction pages bring these together into one record per covered jurisdiction, with verbatim source quotes, source URLs, and SHA-256 source content hashes recorded for primary sources retrieved at verification time.
Maryland Development Fees - Frequently Asked Questions
Does Maryland use impact fees?
Maryland counties use a different mix of developer-side charges than the Texas-style statutory impact fee framework. The most common mechanisms are the Adequate Public Facilities Ordinance (APFO), school facilities surcharge, transportation impact tax, and excise taxes on new construction. Authority for each program is granted under specific state enabling acts and county charter provisions, and the program structure varies meaningfully across Maryland's 23 counties and the City of Baltimore. There is no single statewide impact fee statute comparable to Texas Local Government Code Chapter 395.
What is the Adequate Public Facilities Ordinance (APFO)?
An Adequate Public Facilities Ordinance is a Maryland county tool that conditions subdivision and site plan approval on whether public facilities (schools, roads, water, sewer, public safety) have capacity to serve the new development. Where capacity is constrained, the APFO can require developer-funded mitigation, phasing, or fee-in-lieu payments. APFO programs differ by county and are typically codified in the county's subdivision regulations or planning chapter.
What development fees do Maryland counties typically charge directly?
Maryland counties typically charge fees for zoning map amendments, comprehensive zoning amendments, zoning text amendments, conditional use applications, variance applications, board of appeals appeals, sign variances, administrative adjustments, subdivision plats, site development plan review, water and sewer facilities review, forest conservation, soil conservation, and stormwater management. These are administrative review fees set by each county's Department of Planning and Zoning fee schedule, usually adopted annually through the budget process. Building permit fees are typically administered by a separate Department of Inspections, Licenses and Permits.
Are Maryland development fees published in a single statewide schedule?
No. Maryland does not publish a statewide development fee schedule. Each county maintains its own Department of Planning and Zoning fee schedule, typically adopted as part of the annual county budget effective July 1. School facilities surcharge and transportation impact tax rates are adopted by county council legislation. Water and sewer connection charges are administered by separate utility entities (county Department of Public Works, regional authorities such as WSSC Water, or municipal utility departments).
How do Maryland development fees differ from Virginia or Texas?
Texas authorizes broad statutory impact fees under TLGC Chapter 395 with a uniform procedural framework. Virginia largely does not authorize general impact fees and relies instead on case-by-case voluntary proffers under Va. Code 15.2-2303. Maryland sits between the two: it uses APFO conditions, school surcharges, and transportation impact taxes that are program-specific rather than a single statewide regime, but the rates are published rather than negotiated case-by-case. Cross-jurisdiction comparison in Maryland requires reading each county's planning fee schedule plus the county's APFO, school surcharge, and transportation impact tax legislation separately.
Where does ZoneFee source Maryland fee data?
ZoneFee sources Maryland fee data from official county websites (howardcountymd.gov, montgomerycountymd.gov, and equivalent), county Department of Planning and Zoning fee schedule PDFs, county council adopted legislation, county budget documents (annual fee schedules typically appear in budget appendices), water and sewer authority rate schedules (e.g., WSSC Water), and the Maryland Code via mgaleg.maryland.gov. We do not source fee data from third-party aggregators, news articles, or AI summaries. See the methodology page for the full source hierarchy.
What Maryland Coverage Is Not Yet on ZoneFee
Maryland coverage is expanding. Howard County, Montgomery County, and Frederick County are currently live; additional Baltimore-Washington Corridor, National Capital Region, and Western Maryland counties are queued in our expansion plan but have not yet reached ZoneFee's verification standard. We do not list pending jurisdiction names on this page; transparency on what is and is not yet covered lives on the ZoneFee coverage page. If your project is in a Maryland jurisdiction we have not yet covered, the county's own Department of Planning and Zoning, county council legislation index, and water and sewer authority remain the binding sources for current fees.
