The Rowhome Problems National Maintenance Checklists Get Wrong
If you’re renting a property in Baltimore and using a general maintenance checklist, you might want to stop that. You’ll find hundreds of maintenance checklists online, but they all have a big problem.
They all assume you’re carrying out maintenance for a detached house with a pitched roof, siding, a yard around it, and a furnace installed this century.
But this isn’t the case in Baltimore, where rental stock is attached, masonry, and often over a hundred years old. This means a generic checklist is incomplete. Not only that, it puts attention on the wrong things, so the real risks get missed and don’t get inspected.
We help many owners manage their rental properties, so we can tell you that there are some major issues the national maintenance checklists get wrong.
Party Walls Are a Shared Liability
In a rowhome, the wall between you and your neighbor is a structural element that you don’t have full control over. Water can travel through it, as can pests and fire. If a problem originates next door, it can become your problem too.
Responsibility may not be clear, which is why documentation is so important. During every turnover, that means you should photograph the condition of party walls as well as the roofline at the property line and any shared chimney stacks.
Make a careful note of any stains, cracks, displaced mortar, or other problems, and write down the dates. If a dispute with a neighbor arises a year or two later, or an insurance claim arrives, a dated record will help a lot.
Flat Roofs
If a maintenance checklist says to check your shingles, it’s useless for Baltimore rowhomes. These have flat roofs or low-slope roofs, often with a rubber membrane. These fail for different reasons and at different times.
Drainage is the main issue with flat roofs. Ponding water is the big risk, and it’s often due to a clogged internal drain or scupper rather than the membrane itself.
Clear them regularly, and inspect the seams and flashing where the roof meets adjoining structures and parapet walls. That junction usually fails before the field of the membrane.
Plan for a replacement so you don’t get caught out. Don’t go with the 30-year life quoted for shingle roofs because this won’t apply to flat roofs. Budget for it so you don’t suddenly have to fork out for a repair. A flat roof can go quite suddenly with little warning, so it’s important to be prepared.
Formstone and Masonry Problems
Old brick walls were built to absorb water and release it. Formstone can trap moisture against the brick, as can repointing with hard mortar. The water migrates to the interior, or it freezes and spalls the brick fast, so the repair work is actually making it deteriorate.
Before facade work, always ask a contractor where the moisture will go rather than only finding out what it will look like.
The Vacant Building Next Door

Baltimore has reduced its vacant building count from about 16,000 to under 12,000, and that’s real progress. But new vacancies still appear. For owners, this can be a problem. Why? Because a vacant property next door is an active maintenance threat.
An unmaintained roof can send water through the shared wall. Open structures can attract rodents. A fire in an empty building can spread to the occupied one before it gets noticed.
Careful monitoring is important if you have a vacant property next door. Check the roof and rear of the adjoining property from time to time, and report conditions through 311. Keep all service request numbers because a documented reporting history can be important if damage occurs later.
Older Systems
Older buildings, sometimes over a century old, have infrastructure that a national checklist won’t take into account.
Wiring can be mixed. Knob-and-tube can be spliced into later work, sometimes several eras in one building. Mixed systems can cause problems because the junctions are where failures happen, and many insurers treat them as a coverage issue.
Water service lines might be lead, which affects water quality and tenant health. Requirements change, and replacement programs evolve, so this is something to keep an eye on.
The heat source is often a radiator and boiler instead of forced air, and maintenance is very different. This involves bleeding radiators, monitoring boiler pressure, and protecting pipes. A vacant unit in the middle of winter presents a real burst-pipe risk in a way modern systems don’t, and these are the things you have to plan for.
The One Requirement National Guides Don’t Mention
Maryland’s lead law is very important, and it applies to every rental property that was built before 1978 unless it is certified lead-free.
Owners need to register each unit with the Maryland Department of the Environment, and there is a fee per dwelling unit. They must then renew the registration and get an inspection from an MDE-accredited inspector every time the occupancy changes. They must also provide tenants with all the required disclosures and certificates. From the start of 2026, renewals moved to a two-year cycle.
Penalties can go up to $500 per day per property, with a cap of $100,000, and there are separate civil penalties available. This isn’t something you’ll find on a national checklist, but it could end up costing you a lot.
The Importance of Local Practice

Rowhomes are not the same as small detached houses. They are a different building type with unique failure modes. You need to manage them well and inspect them for what actually goes wrong, rather than for what some general national checklist suggests.
At Premier Property Management, we work with many owners of rowhomes in Baltimore, and we have years of experience with them. We know exactly what to check for and the main problems that can occur.
On top of that, we have a licensed general contractor on staff as well as field managers who carry out inspections regularly, so you don’t have to worry about getting it wrong.
