Living in Baltimore County: towns, schools and the URDL

Living in Baltimore County

Baltimore County and Baltimore City are two separate jurisdictions with two separate governments, tax bills and school systems. The city split from the county on July 4, 1851, and the county now wraps around it on the west, north and east. The county borders York County, Pennsylvania, to the north, Carroll County to the west, Howard County to the southwest, Anne Arundel County across the Patapsco River to the south, and Harford County to the east, with Chesapeake Bay shoreline to the southeast.

County voters adopted a charter in November 1956, replacing the old Board of County Commissioners with a County Council. Today an elected County Executive and a seven-member Council, one member per district, run the county. The County Council's own site says there are no incorporated towns, villages or municipalities anywhere in the county. Towson, Catonsville, Dundalk and Owings Mills are all unincorporated communities, so county zoning, county police and county permits apply at every address, and no town adds a second property tax. Towson has been the county seat since a referendum in 1854.

The map is shaped by the Urban-Rural Demarcation Line, which the Planning Board set in 1967. Inside the line sit the older suburbs ringing the city, served by public water and sewer and crossed by the Baltimore Beltway (I-695). Outside it, the northern half of the county is farmland, reservoirs and stream valleys on wells and septic. I-83 runs north toward Pennsylvania, I-95 northeast toward Harford County, I-795 northwest to Owings Mills, and I-70 west. Deborah Green, a REALTOR with LPT Realty licensed in Maryland since 2002, works with buyers, sellers, investors and people relocating here.

Homes and property types in Baltimore County

Some of the oldest suburban housing in the region is here. Lutherville began in 1852 as a planned community, and its historic district, full of Victorian homes, went on the National Register in 1972. Catonsville grew along Frederick Road, where Baltimore merchants built Victorian and colonial summer houses. Reisterstown dates to 1758 and has a National Register historic district along Main Street. Dundalk was laid out from 1917 on farmland Bethlehem Steel bought in 1916, with two-story stucco houses and steep roofs; its historic district was listed in 1983.

After World War II, farmland inside the line filled with subdivisions. In Cockeysville, land sold from the 1950s on became single-family homes and apartments, and Hunt Valley grew next door as a business community in the 1960s. Perry Hall was largely built out by the late 1990s, and the Honeygo Plan of 1994 laid out growth in its rural northeast. County plans from 1975 on pointed long-term growth to Owings Mills, and the 1984 Owings Mills plan put moderate to high density housing around a town center and transit stations.

Master Plan 2030, adopted by the County Council on January 16, 2024, shifts the focus to redevelopment. It says land for infill inside the URDL is scarce, and it names core retrofit areas, called nodes, for new housing and investment, with corridors such as Liberty Road, Reisterstown Road inside the Beltway, and parts of Catonsville and Essex among the targets. The 2020 plan designated the Middle River Redevelopment Area in the east. Outside the line, the rural north holds large single-family lots, farms and older farmhouses, and zoning there keeps most planned subdivisions out.

Age and location set the inspection list. North of the URDL, plan on a well water test and a septic inspection; since July 1, 2023 the county no longer designs septic systems, and a new or repaired system needs a licensed designer and installer. The county's Ground Water Management records portal holds well and septic records by property. In Middle River, the 600 Aero Acres homes built in 1941 used cement and asbestos panels, which call for care before renovation. Near the Back River, Middle River and the Bay shore, check the FEMA flood map and whether the lot is in the Chesapeake Bay Critical Area.

Towns and communities in Baltimore County

Every place below is an unincorporated community, most of them census-designated places, governed by Baltimore County with no town hall of its own. Community lines are informal and mailing addresses cross them, so the property's tax record at SDAT is the way to confirm that an address is in the county and not in Baltimore City.

Towson

Unincorporated county seat inside the Beltway along York Road (MD 45), home to Towson University, GBMC and UM St. Joseph; areas include Rodgers Forge, Stoneleigh and West Towson.

The rural north

Hereford, Parkton, Sparks, Monkton and Freeland are unincorporated villages outside the URDL, with farms, large lots, wells and septic, and the rail trail running through.

Schools and boundaries

Baltimore County Public Schools (BCPS) runs every public school in the county. Baltimore City Public Schools is a different system, so a house just across the city line is in a different district. BCPS lists about two dozen high schools. It also runs magnet programs at many of them, open to students countywide through an application and lottery, so the school a student attends can differ from the zoned school for the address.

Boundaries in BCPS are changing. On March 19, 2024 the Board of Education adopted a new elementary zone map for central Baltimore County, the end of the district's largest boundary study, and students began moving in the 2024 to 2025 year. Studies in the northwest and southeast followed. Check any address with the Find Your Zoned School locator on bcps.org, and check again close to the move.

What it costs to own here beyond the price

Because there are no incorporated towns, every home pays one local property tax, to Baltimore County, plus the state property tax, both based on the assessment the Maryland Department of Assessments and Taxation (SDAT) sets. Homes on public utilities also carry Metropolitan District charges on the July 1 property tax bill. The sewer service charge is based on the water the property used in the prior calendar year, as reported by Baltimore City, which sends the quarterly water bills to county customers.

Ask for the seller's latest tax bill, because water and sewer benefit assessments surprise buyers. The county levies them on properties in the Metropolitan District to pay for building the water and sewer mains, based on the lot's average width, and they run for 40 years unless paid off early. The Homestead Tax Credit caps how fast the taxable assessment on a principal residence can rise. It takes a one-time application through SDAT, and new owners get the form after the deed records. The credit does not apply in the year after a transfer.

At settlement, the county's Transfer and Recordation Section in Towson collects the county transfer tax and the recordation tax, and the deed needs a lien certificate. Maryland adds a state transfer tax. For a first-time Maryland home buyer who will live in the home, state law lowers that state tax and makes the seller pay it, and each buyer signs a statement under oath. Baltimore County's own transfer tax has no first-time buyer exemption, so plan for the full county tax at settlement.

BGE supplies electricity. The income-based Homeowners' Property Tax Credit and its Baltimore County supplement come through one SDAT application due October 1, and SDAT advises buyers to apply before taking title. Any rental, short-term rentals included, must be registered and licensed with the county before a tenant moves in. On the water, budget for flood insurance where FEMA maps a flood zone; shoreline work falls under the county's Critical Area law.

Buying your first home in Baltimore County

Two programs do most of the work for first-time buyers here. The Maryland Mortgage Program, run by the state Department of Housing and Community Development, offers 1st Time Advantage loans, and most of its products come with a zero-interest deferred loan for the down payment that comes due when the first mortgage ends. Borrowers finish an approved homebuyer education class before loan approval, and the certificate must be dated within 12 months of settlement. Baltimore County's Settlement Expense Loan Program (SELP) helps income-eligible first-time buyers of an existing home inside the county's Community Conservation Areas.

Order matters with SELP. The county requires a two-part first-time homebuyer class, a workshop and one-on-one counseling with a housing counselor first, and a buyer who already has a signed contract is not eligible. The loan is deferred and forgiven if the home stays the buyer's principal residence for the full 15-year affordability period. Line up the class and counseling before house hunting starts. Deborah runs free seminars for first-time buyers that walk through these steps, and she can check whether a home you like sits in a Community Conservation Area.

MMP 1st Time Advantage

Run by Maryland DHCD for first-time buyers; buyers who have not owned a principal residence in three years, and some veterans, can also qualify.

MMP down payment assistance

Most MMP loans pair with a zero-interest second loan that is due when the first mortgage is paid off, refinanced or the home is sold.

Baltimore County SELP

Run by the county Department of Housing and Community Development for an existing home in a Community Conservation Area; the class and counseling come before any contract.

Parks, trails and things to do

The county's biggest open spaces follow its rivers. Gunpowder Falls State Park runs along the Big and Little Gunpowder Falls from the Bay shore at Middle River up into the rural north, and Patapsco Valley State Park lines the river along the county's southwest edge. Loch Raven Reservoir, on the Gunpowder above Towson, is a drinking-water reservoir ringed by woods and trails.

Closer to the Beltway, the county runs nature centers at Oregon Ridge, Cromwell Valley, Lake Roland and Marshy Point, each with trails and programs. The Maryland State Fair fills the Timonium fairgrounds each year from late August into September, and Hampton National Historic Site in Towson opens its mansion for ticketed tours.

Gunpowder Falls State Park

Established in 1959 and covering over 18,000 acres in Baltimore and Harford counties, with more than 120 miles of trails and a beach at Hammerman in Middle River.

Torrey C. Brown Rail Trail

The former NCR rail line, part of Gunpowder Falls State Park, running north through Sparks and Monkton, with parking at Monkton Station on Monkton Road.

Oregon Ridge Park

A 1,100-acre county park in Cockeysville; its nature center was the first the county built and holds a winter maple sugaring festival.

Hampton National Historic Site

At 535 Hampton Lane in Towson, off I-695 exit 27B; the National Park Service tells the history of a former 25,000-acre plantation, with mansion tours by ticket.

Getting around: DC, Baltimore and BWI

The Beltway (I-695) loops through the county around the city, though the Francis Scott Key Bridge on its southeast side collapsed in March 2024, cutting the Dundalk link to Anne Arundel County. I-83 runs north past Timonium and Hunt Valley, with exit 24 at Belfast Road and exit 27 at Mount Carmel Road near Hereford. I-95 crosses the east side, with exit 67 for White Marsh Boulevard (MD 43). I-795 serves Owings Mills and Reisterstown, and I-70 and US 40 head west past Catonsville.

The MARC Penn Line stops at Martin State Airport in Middle River and at Halethorpe in the southwest, with trains to Penn Station in Baltimore, the BWI Rail Station and Union Station in Washington. The Light RailLink stops at Lutherville, Timonium, Fairgrounds, Warren Road, Gilroy Road, McCormick Road, Pepper Road and Hunt Valley, then runs through downtown Baltimore to BWI Airport.

The Metro SubwayLink has three county stations, Owings Mills, Old Court and Milford Mill, and runs in the I-795 median into the city, ending at Johns Hopkins Hospital. Towson sits about 8 miles north of downtown Baltimore, about 16 miles from BWI Marshall and about 42 miles from downtown Washington in a straight line.
