It’s one of the most dreaded moments in a Baltimore landlord’s calendar: a letter from DHCD — the Department of Housing and Community Development — informing you that a housing code complaint has been filed against your property. For self-managing landlords, it can feel like the floor dropping out.

Baltimore City code enforcement isn’t a new concept, but 2026 brought meaningful changes under the Strengthening Renters’ Safety Act, which took effect January 1, 2026. New inspection tiers, new “priority dwelling” designations, and expanded tenant retaliation protections have shifted the compliance landscape. If you own rental property in Baltimore City or Baltimore County and haven’t reviewed your practices since then, this guide is essential reading.

What Triggers a Code Enforcement Inspection in Baltimore

In Baltimore City, housing code complaints are handled by DHCD’s Code Enforcement division. A complaint can be filed by a tenant, a neighbor, or even a city inspector who spots a visible violation while passing by. The most common filing methods are the Baltimore City 311 app, the DHCD online portal, or a direct call to the Housing Hotline.

Baltimore County has a separate code enforcement process run through the Department of Permits, Approvals and Inspections (PAI). While the procedures differ, the fundamental landlord obligations — correct violations promptly, communicate in writing, document everything — are the same in both jurisdictions.

The most common complaint categories filed in Baltimore City include: lack of heat or hot water, water intrusion and mold, structural hazards (broken stairs, compromised roof, damaged flooring), pest infestation, missing or inoperative smoke and carbon monoxide detectors, and electrical hazards. Some of these trigger emergency inspection timelines; others go through the standard queue.

What Happens After the Complaint Is Filed

Once a complaint is received, DHCD schedules an inspection. For standard (non-emergency) complaints, expect an inspector within 7 to 14 business days. Emergency complaints — no heat in winter, no running water, active structural collapse — can trigger a 24-hour inspection response.

If violations are found during the inspection, the inspector issues a Notice of Violation (NOV) that specifies each violation and a correction deadline — typically 30 days for standard issues, though major structural repairs may receive up to 90 days. You’ll receive a reinspection to verify compliance.

Here’s where the Strengthening Renters’ Safety Act of 2026 matters: how quickly you correct violations now directly determines the duration of your rental license. Fix violations within 60 days of being cited and you qualify for a 3-year rental license. Take 61 to 90 days and you receive a 2-year license. Exceed 90 days and you’re issued a 1-year license plus an additional fee of $15 per unit per year. For portfolio landlords managing multiple units, that fee structure compounds fast.

The Act also introduced “priority dwelling” designations for rental buildings with 20 or more units that show a pattern of repeated violations. If your building earns this designation, DHCD is required to conduct at least two city-directed inspections per year — removing any choice about when inspectors arrive.

The Legal Exposure Every Landlord Must Understand

The most consequential — and least understood — aspect of housing code complaints in Baltimore is the retaliation protection built into Maryland landlord-tenant law under § 8-208.1. If you take adverse action against a tenant within 90 days of that tenant exercising a protected right — including filing a housing code complaint — the court presumes the action was retaliatory. The burden then falls on you as the landlord to prove a legitimate, non-retaliatory reason existed.

What counts as “adverse action”? Raising rent. Reducing services. Failing to renew a lease. Beginning eviction proceedings. Even if you had a completely valid, pre-existing reason to take any of these steps, a complaint filed in the last 90 days creates a legal presumption that works against you. Documentation of your original reasoning, dated before the complaint, is essential.

The second major risk is rent escrow under § 8-211. If a landlord fails to correct cited code violations and a court determines the property is uninhabitable or substantially below standard, tenants can file for rent escrow — their rent goes into a court-controlled account rather than to you. The funds remain in escrow until the court determines violations have been remedied. This can mean weeks or months of rent held hostage while repair costs continue to mount.

Finally: operating a rental property without a valid rental license in Baltimore City means you legally cannot collect rent. Any rent received without a valid license is subject to disgorgement, and courts have enforced this strictly since the law was tightened in 2019.

The Most Common Violations — and How to Stay Ahead of Them

The vast majority of code enforcement complaints in Baltimore cluster around the same handful of issues. Understanding what inspectors look for is the first step in making sure they never have reason to cite you.

Heating and HVAC. Baltimore landlords are required to maintain interior temperatures of at least 68°F from October 1 through May 1. HVAC failures are one of the top emergency complaint categories and generate the fastest inspection timelines. Annual HVAC servicing before heating season is a straightforward way to eliminate this risk.

Water intrusion and mold. Maryland’s Tenant Mold Protection Act (effective 2024) expanded landlord obligations around mold disclosure and remediation. Any visible mold or active moisture intrusion is a citable violation. Roof, flashing, and plumbing inspections after every tenant turnover catch these before they escalate.

Smoke and carbon monoxide detectors. Every Baltimore City rental unit must have functioning smoke detectors on every level and within 15 feet of each sleeping area, plus CO detectors on every level where fuel-burning appliances are present. Missing or inoperative detectors are among the easiest violations to avoid — and the easiest for an inspector to cite.

Structural and exterior hazards. Broken steps, handrails, deteriorating roof flashing, peeling exterior paint (especially in pre-1978 homes with lead paint obligations), and damaged gutters all qualify as citable conditions. Regular exterior walk-throughs — especially after winter — catch these early.

How to Respond Correctly When You Receive a DHCD Notice

If you receive a Notice of Violation, the playbook is straightforward — but every step matters.

First, read the notice carefully and note every cited violation and its correction deadline. Then contact your maintenance provider immediately and document the date of the contact. Get repair work scheduled within the first week if at all possible — your goal is to resolve everything well within the 60-day window to protect your 3-year license term.

Second, communicate with the tenant in writing to confirm that repairs are being scheduled. This creates a documented record and often reduces the likelihood of escalated complaints. A tenant who knows repairs are coming is far less likely to call DHCD again.

Third, photograph all completed repairs with date-stamped images. When the reinspection occurs, you want clear documentation that every cited item has been addressed — not just partially resolved. Inspectors look for full compliance, not good-faith effort.

Fourth, review your records for any pre-existing lease issues or tenant performance concerns. If any adverse action against the tenant was already planned before the complaint was filed, make sure that reasoning is documented in writing, dated, and preserved. You may need it if a retaliation claim is raised later.
