The short answer
Landlords are not automatic insurers of your personal property. In general, a landlord is responsible for damage to your belongings when their own negligence caused it — for example, ignoring a leak they knew about until it ruined your furniture. For damage from something outside their control, like a sudden pipe failure nobody could have predicted, a break-in, a fire started by another tenant, or a storm, the landlord is usually not on the hook, and your own renters insurance is what actually covers you.
The general rule: negligence, not automatic liability
Landlord-tenant law doesn't generally make a landlord strictly liable for everything that happens to your things just because it happened in their building. What typically matters is whether the landlord knew about a problem, had a reasonable chance to fix it, and failed to — the same negligence standard that shows up throughout landlord-tenant law. Maryland's dangerous-conditions law is a good illustration of the underlying idea: it requires a landlord to fix problems like leaks and sewage failures within a reasonable time once properly notified (Md. Code, Real Prop. § 8-211), and a landlord who ignores that duty is exactly the kind of landlord who ends up facing a negligence claim if the ignored problem eventually damages a tenant's property. A landlord whose water heater failed suddenly and without warning is in a very different position.
Where the record you kept starts to matter
If you already reported the underlying problem in writing before the damage happened, that record is exactly what turns bad luck into a negligence claim. This is one more reason to always report habitability problems in writing rather than only mentioning them in person: a text or email with a date on it is what shows your landlord had notice and time to act.
What your lease might already say
Some leases include a clause saying the landlord isn't liable for tenant property damage under any circumstances, or that the tenant is required to carry renters insurance. A blanket disclaimer doesn't necessarily erase liability for a landlord's own negligence, but it does make clear the landlord isn't accepting responsibility for things outside their control, which is most of what can go wrong with your belongings. Read this section of your lease before you assume either way.
A related clause worth checking is whether your lease requires you to report problems within a certain number of days, or in a specific format. Some leases tie a tenant's right to make a damage claim to having followed the lease's own reporting process — another reason the written notice you send when you first spot a problem does double duty, protecting both your habitability rights and any later property-damage claim.
Why renters insurance matters here
Because a landlord's liability is narrow and depends on proving negligence, renters insurance is what actually protects your belongings in most other situations: theft, fire, storm damage, a neighbor's plumbing failure, and plenty of scenarios where nobody was clearly at fault. Renters insurance is also generally quite inexpensive relative to what it replaces, since it's only insuring your personal property and liability, not the building itself, which is the landlord's separate and typically much larger policy. If you don't already have a policy, this is the kind of situation that makes the case for getting one before something happens, not after.
What to do if something is already damaged
Photograph the damage and the cause if you can see it — the leak, the broken pipe, the point of entry for a break-in. Get a police report for theft or vandalism. If you believe your landlord's negligence caused the damage, send a written claim describing what happened, when you reported the underlying problem, and what you're asking for: replacement cost, a repair, or a rent credit. Keep receipts or resale-value estimates for what was damaged, and don't discard the damaged items themselves until the claim is resolved if you have anywhere to store them — a claims adjuster or a landlord disputing the claim may want to see them directly.
