01The state file and the county file rarely agree on timing.
The Maryland Historical Trust (MHT), a unit of the Maryland Department of Planning, is the State Historic Preservation Office and the keeper of the Maryland Inventory of Historic Properties. The inventory tells you what a building is. It does not tell you that a county has budgeted a courthouse roof, that a nonprofit has applied for an African American Heritage Preservation Program grant, that a developer has filed a Part 1 for the competitive commercial credit, or that the Department of General Services is about to advertise design services.
Those facts sit with 23 counties and Baltimore City, with state agencies and universities, with the Board of Public Works, and with the grant boards that MHT itself staffs. Maryland's public record is deep. The complication is that each system answers a different question and publishes on its own calendar.
02The Maryland reference desk
None of these is a list of active projects. Each settles one part of the trail.
| Public system | What it holds | How to read it |
|---|---|---|
| Medusa (MHT) | Maryland's Cultural Resource Information System: Maryland Inventory of Historic Properties records, National Register listings, determinations of eligibility and properties under MHT preservation easements, searchable by map and by text. | Confirms what has been documented and whether MHT already holds an easement. Archaeological records are restricted to qualified professionals; public use is limited to above-ground resources. |
| MHT Project Review | Review of federal undertakings under Section 106 and of state undertakings under the Maryland Historical Trust Act (State Finance and Procurement Article §§ 5A-325 and 5A-326). MHT maintains a public Project Review and Compliance Log of submittals. | A log entry confirms a state or federal funding, permitting or licensing connection, or an anticipated one; project maturity varies from pre-application consultation to fully developed undertakings. Entries record the agency, county and MHT's finding, from no adverse effect to conditional findings to ongoing consultation. |
| Historic Revitalization Tax Credit | Three credits. The small commercial credit is 20% of eligible expenses, capped at $50,000 in a 24-month period, for projects with $5,000 to $500,000 in expenses. The competitive commercial credit is 20%, capped at $5 million per project. A homeowner credit covers owner-occupied houses. Eligibility can come from National Register listing or from local designation plus an MHT determination that the property is National Register-eligible. |
Small commercial applications are accepted first-come until the annual cap is reached. The competitive round has one deadline a year (August 31 in 2026). A Part 2 approval means a rehabilitation plan exists and MHT has reviewed it; it does not prove financing. |
| Historic Preservation Capital Grant Program | Grants of up to $100,000 for acquisition, rehabilitation and restoration, and for plans and specifications (nonprofit and local government applicants). Nonprofits are exempt from the dollar-for-dollar match. The program provides $1 million per round. | A capital award is a strong sign of a defined scope with cost estimates and owner consent. Assisted properties must convey a preservation easement to MHT. |
| African American Heritage Preservation Program | $5 million a year in capital grants, jointly administered by MHT and the Maryland Commission on African American History and Culture. Awards up to $250,000; no match required. Local governments, nonprofits, and businesses or individuals with a high public purpose may apply. | The application opens in spring and closes July 1; awards go to the Board of Public Works the following winter. Properties listed in or eligible for the National Register may be subject to an MHT easement. |
| Maryland Heritage Areas Authority | Roughly $3 million a year in capital and non-capital project grants within Maryland's 13 certified heritage areas. Capital grants up to $100,000 with a one-to-one match of non-state funds; pre-development and design costs are eligible. | Grant cycles open in December. Location inside a certified heritage area is also relevant to tax credit eligibility for some contributing properties. |
| DGS Design, Construction and Energy | The Department of General Services selects design consultants and construction contractors for state capital improvement and maintenance projects and participates in the Public School Construction Program and community college capital program. | Architects and engineers are selected on qualifications with fees negotiated afterward. Larger or unusual A/E procurements and construction bids above the posting threshold appear on eMMA. |
| eMaryland Marketplace Advantage | The state's e-procurement platform. Active solicitations and awarded contracts are posted there, and many counties, school systems and local agencies use it as well. | Vendor registration is required to bid. eMMA is the formal market record, not the first record; owners have usually defined the project long before posting. |
| Main Street Maryland | The Department of Housing and Community Development's coordinating program for the Main Street America network, begun in 1998 with three communities and now supporting more than 50. | Points to organized downtown programs whose building priorities surface in DHCD funding announcements and local plans. Project facts still come from the municipality. |
03Maryland runs on a calendar.
Each funding program has its own rhythm, and where a project sits in that rhythm says a great deal about how mature it is.
Spring
African American Heritage Preservation Program applications open (April 2, 2026 for the FY2027 round) and MHT and the Commission run workshops. An owner attending a workshop is assembling a scope and a cost estimate.
July 1
AAHPP applications close. A filed application means a defined scope, a budget, property-owner permission and usually a design professional's estimate.
August 31
Competitive commercial tax credit deadline. A Part 2 filing means a rehabilitation plan exists. Certification is not financing.
Autumn and winter
MHT's capital and non-capital grant rounds follow their posted guidelines and deadlines, and the Heritage Areas Authority opens its next cycle in December (the FY2028 cycle opens December 2026).
January and February
AAHPP awards go to the Board of Public Works. BPW agendas are public and itemized, and BPW is also where state construction contracts and many grants receive formal approval.
04Four Maryland markets, four different trails
Baltimore City
Baltimore's Commission for Historical and Architectural Preservation reviews work in local districts and landmarks and administers the city's own historic tax credit, which can apply to the same building as the state and federal credits. Industrial and warehouse conversions, school reuse, and rowhouse-scale rehabilitation each leave a different mix of records: city capital budget, Baltimore Development Corporation actions, state tax credit certifications and MHT review of state-assisted work.
Annapolis and the Washington suburbs
State-owned buildings in Annapolis move through DGS and the Board of Public Works. In Montgomery and Prince George's counties, large planning systems, county historic preservation commissions and county capital improvement programs carry most of the record, and federal ownership adds Section 106 consultation. Density and redevelopment pressure mean planning cases often say more about timing than any statewide source.
Western Maryland
Frederick, Hagerstown and Cumberland combine Main Street districts, canal and railroad heritage, and certified heritage areas. In Cumberland, the Canal Place Preservation and Development Authority is itself a public owner. Heritage Areas grants, county budgets and Main Street design work tend to surface projects here before any state procurement notice.
The Eastern Shore and Southern Maryland
Chestertown, Easton, Cambridge, Salisbury and the Southern Maryland counties produce fewer records, which makes each one heavier. A county council vote to fund a courthouse study, a small AAHPP or capital grant award, or a Main Street facade program can be the entire visible trail. Coastal flooding and resilience funding increasingly shape what gets prioritized.
05Board approval is where Maryland gets specific.
Much of Maryland's public spending passes through the Board of Public Works, whose agendas itemize grant awards, capital contracts and property actions. By the time a solicitation is on eMMA, MHT may already have reviewed the undertaking, the county may already have budgeted it, a grant panel may already have ranked it, and BPW may already have approved the grant that pays for it.
None of that makes every early record an opportunity. It does mean that firms watching only eMMA and county bid pages are seeing the last public version of a project. See where preservation work appears before an RFQ, RFP or bid notice →
