A new townhouse in Frederick County is charged $22,881 in school and library impact fees under the county's FY27 schedule. A new single-family detached home is charged $20,111. The smaller home on the smaller lot, usually the lower-priced way into new construction, pays $2,770 more in combined fees.
The fee doesn't depend on square footage, lot size or sale price. It is set by dwelling category alone. A flat charge takes up a bigger share of a cheaper home. So when you set a new townhouse beside a resale townhouse, or beside a new detached house, the two prices aren't built from the same costs.
The fee follows the unit type
Here is the county's current schedule, dated October 1, 2026:
| Dwelling type | Public school fee, FY27 | Library fee, FY27 | Total, FY27 |
|---|---|---|---|
| Single-family detached | $19,109 | $1,002 | $20,111 |
| Townhouse/duplex | $21,969 | $912 | $22,881 |
| Other residential, incl. multifamily | $9,429 | $566 | $9,995 |
The school fee is where the gap comes from. The townhouse school fee is $2,860 higher than the detached-home fee, about 15 percent more. The fee applies to all land in Frederick County, inside incorporated towns as well as outside them. A townhouse in Brunswick is charged the same as one off Ballenger Creek Pike.
Set that charge against what builders were advertising on October 4, 2026, and you can see how the weight shifts:
| Community | Builder | Advertised starting price | Townhouse fees as share of base |
|---|---|---|---|
| Courtyards of Overlook, Frederick | DRB Homes | $399,000 | about 5.7% |
| Lake Linganore Westridge Townhomes, Frederick | Ryan Homes | $444,990 | about 5.1% |
| Sycamore Springs Townhomes, Frederick | Ryan Homes | $449,990 | about 5.1% |
| Park Place at Ballenger, Frederick | DRB Homes | $464,990 | about 4.9% |
| Brunswick Crossing Townhomes, Brunswick | DRB Homes | $547,196 | about 4.2% |
For comparison, take the detached fee as a share of Frederick County's August 2026 median sale price of $525,000. That works out to roughly 3.8 percent. These starting prices change often and include whatever each builder chooses to fold in. The county's schedule doesn't say how much of the fee a builder passes on to the buyer. What it does fix is a cost that every new townhouse carries before anyone negotiates.
Where the higher townhouse number comes from
The logic comes from the county's own fee model. The county published an impact-fee model in 2017. It set each school-level fee by multiplying a dwelling type's student-generation rate by the net local capital cost per student, then adding up the elementary, middle and high school figures. In that model, the maximum supportable school fee was $16,248 for a townhouse or duplex and $14,132 for a single-family home. The county's 2019 annual report notes that the consultant's proposed changes never went to legislation. So the model explains the reasoning, but it isn't the formula behind today's exact dollar figures.
The county's December 2025 Pupil Yield Study gives the current inputs that reasoning depends on. Countywide, townhouses average 0.49 public school students per unit across all grades. Single-family detached homes average 0.45, and multifamily units 0.25. The study says that "across all levels, the highest average rates overall are found in the townhouse dwelling unit type," and it lists townhouses in the Urbana Middle and Urbana High attendance areas among the highest rates at those levels.
The ranking hasn't held steady from study to study. Townhouses averaged fewer students per unit than detached homes in 1998, 2005 and 2022, and more in 2017 and 2025. The fee hasn't moved up and down with them. Townhouses still carried the higher fee after the 2022 study showed them at 0.45 against 0.50 for detached homes.
The fee gap itself goes back about a decade. In the 2014 schedule, the detached fee was slightly higher at $13,478, compared with $13,412 for a townhouse. By the July 1, 2016 schedule the order had flipped, at $14,207 for a townhouse and $14,112.50 for a detached home, and by July 1, 2017 it was $15,002 against $14,747. In Frederick News-Post coverage of that increase, proposed by then-County Executive Jan Gardner, Councilman Tony Chmelik was quoted opposing the higher cost. Townhouses have paid more ever since.
A rate that keeps climbing, and a payment date that just moved
The fees rise every year. In FY25 the school fee was $17,925 for a detached home and $20,609 for a townhouse. Both have gone up about 6.6 percent by FY27, and the dollar gap has widened from $2,684 to $2,860.
On October 1, 2026, the timing changed too. Maryland's Housing Certainty Act, SB 325, became Chapter 590 of the Laws of Maryland 2026. For residential permit applications submitted on or after that date, Frederick County no longer collects the impact fee when it issues the permit. The fee is now assessed and collected no more than 30 days before the scheduled final inspection, and the inspection can't happen until it's paid. The fee is charged "at the current rate at the time of the final inspection."
That last detail matters to a buyer. A townhouse permitted this fall and finished after the next July 1 rate change will be charged the rate in effect at final inspection, not the rate in effect when the contract was signed. The state law also carves out fees that finance county debt incurred on or before January 1, 2026. The Maryland Building Industry Association called the deferral a big win for housing production, saying it would improve project financing and keep capital flowing. For a buyer, the practical question is how the purchase agreement handles a fee that is now set close to delivery.
Why the resale comparison shifts
A resale townhouse has no impact fee in its price, because the fee is charged only on new construction. That changes how a new-construction base price lines up against nearby resales. Some of the difference is finish and warranty, and some is a county charge of more than $22,000 that the older home paid years ago, at a lower rate, or never paid at all.
The resale side has been getting thinner. In August 2026, Frederick County had 766 active listings, down from 932 a year earlier. Months of inventory fell from 3.1 to 2.5. Settlements fell 7.4 percent to 299, while the median sale price rose 5.0 percent to $525,000. Median days on market went from 14 to 17. Those figures cover all housing types, not townhouses alone. Still, they describe a market where fewer listings push buyers toward new construction, and new construction comes with the fee.
More townhouses are coming, each with the same fee
The pipeline leans toward attached homes. The City of Frederick Planning Commission approved a first phase of Highland Trail: 100 townhomes at 198 Monroe Avenue, across from the fairgrounds, on a site whose master plan allows 550 residential units. At Frederick Brickworks, Greenberg Gibbons' 65-acre redevelopment at East and South streets, the plan calls for 700 apartments and 320 for-sale townhomes, with the first phase targeted for completion in 2028. The apartments fall in the lower "other residential" category. The townhomes fall in the highest.
The county's February 2026 housing study estimates that 31,853 new units are needed by 2035, including 20,546 for sale. Of that for-sale demand, 12,801 units fall above 120 percent of area median income. The county's priority list includes revising its moderately priced dwelling unit policy and exempting affordable housing from APFO. Both are listed as strategies. Neither changes the impact fee on a market-rate townhouse today.
FAQ
Does someone buying a resale home pay the impact fee? No. The county charges the fee on new residential construction when a dwelling is built.
Does the fee apply in the City of Frederick and in towns like Brunswick? Yes. The ordinance covers all land in Frederick County, including every municipality.
Is the impact fee the same thing as the APFO school construction fee? No. The school construction fee is a separate, older option. It's limited to developments approved by an APFO letter or development rights agreement signed by July 20, 2016, and it's paid on top of the public school impact fee. No new projects can choose it.
How does the county classify a mobile home? The county's schedule treats mobile homes as single-family detached.
