Quick answer
Before you offer on a Baltimore rowhome, run the free public lookups: Baltimore City's Active Notices search and CoDeMap for a vacant building notice, the city permits search for past work, SDAT's ground rent registry, the Baltimore Service Line Partnership map for the water service line, and the city water account lookup. A City lien certificate, which shows all charges due the City including water and sewer bills, should be reviewed before settlement. Then use a licensed Maryland home inspector to look closely at the party walls, roof and flashing, basement water, wiring, and plumbing, and add specialists where the inspector recommends.
- Vacant building notice
- Check Active Notices or CoDeMap by address before you offer
- Ground rent
- Only ground rents on SDAT's registry are legally collectible
- City lien certificate
- $55, ordered online, shows water and sewer charges
- Homes built before 1978
- Federal rules give you 10 days to test for lead paint unless you waive it
Step 1: free public lookups before you offer
These take a few minutes each and use only the address. Do them before you write an offer, because what they turn up can change the price you offer or whether you offer at all.
| Check | Where to look | What it tells you |
|---|---|---|
| Vacant building notice | Baltimore City DHCD Active Notices search (cels.baltimorehousing.org/Search_On_Map.aspx) or CoDeMap (cels.baltimorehousing.org/codemapv2ext) | Whether the City has issued a vacant building notice or other active notices. If a notice is still unabated, the seller must disclose it in writing before the contract is signed, and only a validly issued Use and Occupancy Permit certificate removes it. |
| Permit history | Baltimore City DHCD permits search (cels.baltimorehousing.org/Search_TM_Map.aspx) | Permits issued for the address. Compare them with any renovation, addition, new electrical, plumbing, or heating and cooling work the listing describes, and ask the seller for permits and final inspections for recent work. |
| Ground rent | SDAT Real Property Search: find the property, then View Ground Rent Registration and View Ground Rent Redemption | Whether a ground lease is registered. Only ground rents on SDAT's registry are legally collectible by the ground lease owner. |
| Water service line material | Baltimore Service Line Partnership map (search by address) | Whether the City lists the water service line material as unknown. You can check the pipe yourself at a showing or inspection with a magnet and a coin, as the City's survey explains. |
| Water account | Baltimore City water account lookup (pay.baltimorecity.gov/water), by account number or service address | The water account for the address. Ask the seller or title company about any open balance. |
| City liens | Baltimore City lien certificate, ordered online through the City payment portal | All charges and assessments due the City, including water and sewer bills and property taxes. There is no free online lien check; the certificate costs $55. |
Step 2: what to ask the inspector to focus on
A home inspection is your choice in Maryland, and home inspectors must hold a Maryland license, which you can check on the Maryland Department of Labor's license search. Rowhomes share walls and roofs with their neighbors, so a few items deserve extra attention. Ask your inspector to note anything they could not reach or see.
- Party walls: cracks, moisture stains, or gaps in the shared walls, especially where they meet the roof and the front and rear walls, and any openings between your home and the neighbor's.
- Roof and flashing: many rowhomes have low-slope roofs. Ask whether the inspector walked the roof, the condition of the roof covering, and the flashing where your roof meets the neighbors' roofs, chimneys, and skylights. Ask about drains, gutters, and downspouts.
- Basement water: stains, efflorescence (white mineral deposits), active leaks, sump pumps, and where downspouts and yard grading send water.
- Electrical: the panel, the type of wiring (older homes can still have outdated types such as knob-and-tube), grounding, and any work that looks unpermitted. If the inspector flags wiring, ask a licensed electrician to evaluate it, and ask your insurance agent whether the wiring type affects coverage before your contingency ends.
- Plumbing: the material of the water service line where it enters the basement, supply and drain pipes, the water heater, and signs of past leaks. A camera inspection of the sewer line is an optional specialist test.
- Additions and changes: rear additions, finished basements, removed walls, and roof decks. Match them to the permit search from Step 1.
- Heating and cooling, windows, and chimneys: age, condition, and any signs of water getting in.
Lead paint in homes built before 1978
For homes built before 1978, federal rules require the seller to give you the EPA lead pamphlet and disclose any known lead-based paint and reports before you sign, and to give you a 10-day period to have a lead paint inspection or risk assessment done, unless you agree in writing to change or waive it. If you plan to rent the home out, Maryland requires pre-1978 rental units to be registered with the Maryland Department of the Environment within 30 days of buying and to pass a lead inspection before each new tenant moves in.
If you plan to rent it out
- Baltimore City rental licenses no longer transfer to a buyer since January 1, 2026. A buyer must apply for a new license within 60 days.
- Pre-1978 units must be registered with MDE and pass a lead inspection before each new tenant, as above.
- See our Baltimore City landlord guide for the full rental license and inspection rules.
When to bring in a specialist
A general home inspection is a visual check. If the inspector recommends further evaluation, bring in the right specialist before your inspection contingency ends: a structural engineer for party wall, foundation, or framing concerns; a roofer for the roof and flashing; a licensed electrician for wiring; and a plumber for the service line or a sewer camera inspection. Ask each for a written estimate so you can negotiate with real numbers.

Frequently asked questions
How do I check whether a Baltimore house has a vacant building notice?
Search the address on Baltimore City DHCD's Active Notices search or on CoDeMap. If a vacant building notice is still unabated, the seller must disclose it in writing before you sign the contract, and only a validly issued Use and Occupancy Permit certificate removes the notice.
How can I find out whether a Baltimore rowhome has a lead water service line?
Search the address on the Baltimore Service Line Partnership map, which shows whether the City lists the service line material as unknown. You can also look at the pipe where it enters the basement; the City's survey explains how to check it with a magnet and a coin.
How do I see what permits were pulled on a Baltimore City property?
Use Baltimore City DHCD's permits search on its CELS site and search by address. Compare the results with any renovation or addition the listing describes, and ask the seller for permits and final inspections for recent work.
Does the Baltimore City lien certificate show unpaid water bills?
Yes. Under the City Charter, a lien certificate shows all charges and assessments due the City, including water and sewer billings. It costs $55, is ordered online, is sent by email, and takes about seven business days.
How do I check whether a Baltimore rowhome has registered ground rent?
Look up the property on SDAT's Real Property Search and open View Ground Rent Registration. Only ground rents on SDAT's registry are legally collectible, and the same record shows whether a redemption has been filed.
