Baltimore Rental License and Inspection Requirements

Registration first, license second

Baltimore splits the obligation in two. According to the Baltimore City Department of Housing and Community Development (baltimorecity.gov), all non-owner-occupied properties, including one and two-family dwellings, multi-family dwellings of three or more units, vacant buildings, and vacant lots, must be registered each year, whether or not the property is occupied or generating income. Rental properties must then also be licensed to operate, on top of the registration.

The statute has teeth. Under Baltimore City Code Article 13, § 5-4, an unlicensed operator may not rent or offer to rent a dwelling, and may not charge, accept, retain, or seek to collect any rental payment for it. Each day of violation constitutes a separate offense. In a city where the license gates the rent itself, letting it lapse is not paperwork risk, it is revenue risk.

The inspection is outsourced to the private market

Like Denver, Baltimore runs a third-party model: the city sets the standard and a private inspector performs the work. According to DHCD (baltimorecity.gov), the licensing inspection must come from a Maryland State Licensed Home Inspector who is registered with DHCD to conduct rental inspections in Baltimore City, and the report must be submitted within 90 days of the inspection. Reports outside that window are rejected, which means a new inspection, not a resubmission.

The city's own inspection form shows exactly what gets checked, one form per unit. The inspector must also certify they hold no financial interest in the property, its owner, or its operator.

What changed on January 1, 2026

The Strengthening Renters' Safety Act, Ordinance 23-0357, took effect January 1, 2026. According to DHCD's summary of the Act (baltimorecity.gov), it replaces the old term structure, where initial licenses ran two years and renewals three, with a flat two-year term for every rental license. Licenses also stopped being transferable: a buyer must obtain a fresh license within 60 days of taking ownership, so the license is now a closing-checklist item, not an inherited asset.

The Act's sharpest edge is the priority dwelling program. A property of 20 or more units becomes a priority dwelling if it hit two or more of four triggers in the previous year: violation notices unabated for 90 or more days, four or more violation notices issued, 311 calls above thresholds for health and habitability concerns, or a HUD INSPIRE inspection score of 79 or below. Priority dwellings get city inspections at least twice a year, separated by four months, and can face license denial, suspension, or revocation. Owners must also post the rental license number in common areas, leases, and advertisements; failing to post carries a $250 citation.

The lead layer sits on top

A Baltimore license application must include current lead certification information for each unit, which pulls in the state regime. According to the Maryland Department of the Environment (mde.maryland.gov), all pre-1978 rental properties must be registered with MDE under an owner-specific tracking number, at $75 per unit covering two years effective January 1, 2026, and must meet the Full Risk Reduction Standard at every change in occupancy, including passing a lead-contaminated dust inspection before a new tenant moves in. For a pre-1978 Baltimore rowhome, every turnover is therefore already an inspection event under state law, before the city license cycle even comes due.

How Baltimore's model compares with the other jurisdictions we verified, from cities that send their own inspectors to cities that let owners self-certify, is mapped in our rental inspection ordinance reference.
