If you buy a vacant house in Mount Rainier, the months it stays empty now come with their own price tag. For the fiscal year that began July 1, 2026, the City kept its rate on occupied single-family homes and townhouses at $0.75 per $100 of assessed value. It raised the rate on "vacant developed property" from $2.50 to $4.00 per $100. Every other category stayed level. City Manager Kourosh Kamali's budget letter describes this year's budget as one where "the City's tax rates remain constant in all categories except for the increase in the vacant property tax."
That one change affects anyone shopping for a fixer-upper here. On an empty house, the renovation timeline is now part of the purchase math.
The Full Bill, With County and State Added
The City rate is only one piece of a Mount Rainier property tax bill. Prince George's County and the State of Maryland add their own shares. The Maryland Department of Assessments and Taxation 2026–2027 rate table lists each component for Mount Rainier.
| Mount Rainier class, FY2027 | City | County | State | Combined per $100 |
|---|---|---|---|---|
| Residential, occupied | $0.75 | $0.879 | $0.112 | $1.741 |
| Townhouse, occupied | $0.75 | $0.879 | $0.112 | $1.741 |
| Vacant developed | $4.00 | $0.879 | $0.112 | $4.991 |
The County and State shares are the same in both rows, so the whole difference comes from the City line, and it is large. A vacant developed property pays a combined rate almost three times that of the same house with someone living in it.
Here is a hypothetical house assessed at $400,000, before any credits or other charges on the bill:
- Occupied, at $1.741 per $100: about $6,964 a year.
- Vacant developed, at $4.991 per $100: about $19,964 a year.
- The gap: about $13,000 a year, all of it from the City's vacant rate.
For a renovation buyer, that gap belongs in the same spreadsheet as materials and labor. It also changes which renovation plan makes sense. A slow, phased gut job with nobody in the house costs a lot more to carry here than it did a year ago.
Vacancy Is Defined by What the City Can See
The City defines vacancy by physical conditions it can observe, with no mention of what the owner plans to do.
In a March 2023 notice to vacant property owners, the City quoted Chapter 3B, Section 103(F) of its code. A vacant building is one that is "empty," one that is "not occupied or used by the owner, tenant, agent of the owner, or other person having the permission of the owner on a regular and habitual basis for the usual and customary purposes for which the building is designed and lawfully permitted," or one that is partially vacant. The same notice lists the signs the City considers when deciding:
- Electric, gas or water meters not running or showing low usage
- Accumulated mail
- A neighbor complaint
- Not enough furniture visible
- Open accessibility
- Deferred maintenance, such as loose gutters, heavy paint chipping or overgrown grass
- Boarded-up windows or doors
Compare that list with a typical estate sale or a house in the middle of a gut renovation. Low utility use, little furniture and peeling paint describe a lot of the older houses that renovation-minded buyers go looking for. The notice also covers residential and commercial buildings alike, so the rules reach houses as well as storefronts.
One more line in that notice matters at the start of a sale: "A vacant building must be registered even if the building is offered for sale or lease." Having a house on the market does not exempt it.
A Second Program Runs Alongside the Tax
Vacant buildings also fall under a separate City registration program with its own fees. The City's FY2027 fee schedule lists vacant-building registration at $1,000 for a single-family building, $600 for a utilitarian building, and $1,600 for commercial, industrial, multifamily and mixed-use buildings. Vacant lots are $600 under 10,000 square feet and $1,000 above that. According to the City's vacant building and lot registration form, building fees are charged in six-month periods. The 2023 notice describes those cycles as July through December and January through June, with vacant lots billed once a year. The City's Finance Department can say how the $1,000 single-family figure applies to those billing periods for a particular property.
The form asks for some specific things:
- Contact details for everyone with an ownership interest
- The date the vacancy began
- A written plan of action with a timeframe
- A demolition timetable and permits, if demolition is proposed
- Notice to the City Manager within 14 days of a change of ownership or authorized agent
Under the 2023 notice, failing to comply with registration is a municipal infraction under Chapter 3B, Section 106E. For vacant lots, the form names the amounts. A missed registration statement or fee is a $300 infraction, another $300 can follow for each further 60 days, and overdue fees can become a lien collected like delinquent property taxes.
The City's published material treats registration and the tax rate as separate programs, one run through the fee schedule and the other through the tax classification that Prince George's County bills. The 2023 notice tells owners who disagree with their classification, or with how long it has lasted, to contact the City's Code Compliance Division and ask for an application for an exemption or termination of vacant classification. Code Compliance is the office to contact about the specifics of any one property.
Why the Council Raised It, and What Comes Next
The council discussed the increase in public sessions this spring, and the minutes show a policy aimed at getting buildings filled, especially along the commercial blocks.
At a February 17, 2026 budget work session, Vice Mayor Danielle Carter suggested raising the rate from $2.50 to $4 for the coming year, "with a potential additional increase of $1 the following year." According to the official minutes, she said the existing rate gave property and business owners too little incentive to fill vacancies, and that Ward One residents felt they carried a disproportionate share of the tax burden because of the number of vacant properties there.
At the April 7 first reading of the budget ordinance, Vice Mayor Carter proposed $5.00. The April 7 minutes record her saying the purpose "was not primarily to generate additional revenue, but to encourage property owners to fill vacant storefronts and properties." Councilmember Jenny Hoffpauir concurred. Councilmember Joseph Jakuta supported $5.00 as well, saying that short-term revenue could pay for professional services that help vacant properties fill more quickly, including help with DPIE processes.
Mayor Celina Benitez asked for more analysis before any increase. She noted that properties had moved in and out of the program over time, and she raised fairness questions about newer owners compared with long-standing properties in the program.
The FY2027 budget ordinance, Ordinance 03-2026, adopted $4.00. That figure sits between the proposals, and the debate over going higher is already on record. Anyone planning a renovation that runs into the fiscal year starting July 1, 2027 should know that a further $1 increase was raised publicly in February.
How Mount Rainier Compares Next Door
The same State table shows that this rate is specific to Mount Rainier among its neighbors. Hyattsville's regular combined rate is $1.626 per $100, Brentwood's is $1.388, and College Park's noncommercial rate is $1.415. None of them has a separate "Vacant Developed" line in the table. Mount Rainier does.
For occupied homes, Mount Rainier's $1.741 sits a little above those neighbors. For an empty house, its $4.991 is in a different category altogether. Two older houses with similar list prices on either side of a city line can cost very different amounts to hold while they're empty.
Questions to Ask Before Offering on an Empty House
- Is the property currently registered with the City as a vacant building, and since when?
- Which class appears on the most recent tax bill, residential or vacant developed?
- How many months will the house realistically sit empty between closing and move-in?
- Is there a written renovation plan with a timeframe that could go on the City's registration form?
- Who will notify the City Manager of the ownership change within 14 days, and when does that period begin?
FAQ
Does listing a vacant house for sale take it out of the program? No. The City's notice says a vacant building must be registered "even if the building is offered for sale or lease."
Is the $4.00 rate the whole tax? No. It is the City's share. With the County and State components, the combined FY2027 rate for vacant developed property in Mount Rainier is $4.991 per $100 of assessed value.
Who handles a disagreement over vacant classification? The City's Code Compliance Division, which issues applications for an exemption or termination of vacant classification.
Could the rate rise again? A further $1 increase for the following year was suggested at the February 17, 2026 work session. Any change would be set in a future budget ordinance.
