Can this Maryland property operate as an Airbnb?
Check local eligibility before buying or advertising. Baltimore’s primary-residence license, Montgomery County’s primary-residence rules and Ocean City’s rental licensing serve different operating models. Maryland’s new statewide safety requirements add another layer; they do not make a locally prohibited rental legal.
- Identify the government. Verify municipal boundaries and the parcel’s zoning district, not just the mailing address.
- Describe the business. State who owns and lives in the unit, whether the host stays overnight, rental length, bedrooms and guest count.
- Get the approval path in writing. Ask about zoning, rental licensing, inspections, private restrictions and whether a buyer needs new approvals.

This guide selects Baltimore for the measured “baltimore airbnb laws” search question, Montgomery County for the DC-area primary-residence comparison, and Ocean City for its distinct resort licensing and stay-length rules. It is not a ranking of rental returns.
October 1, 2026: safety duties already apply
The Jillian and Lindsay Wiener Short-Term Rental Safety Act is enacted, effective October 1, 2026. Its safety provisions cover units offered for stays shorter than 30 consecutive days.
Now: equip and document the unit
Post an exit diagram and emergency numbers. Provide a working extinguisher, smoke alarms and carbon monoxide alarms. Follow applicable fire codes; required smoke alarms must be interconnected or meet an authorized alternative. Replace nonworking, undated or over-ten-year-old alarms.
By July 1, 2028: local inspection framework
Counties and Baltimore City allowing these rentals must require annual compliance inspections by this deadline. Existing local inspections may already apply. Keep compliance documentation and ask the local office about its implementation.
Source: Enacted Chapter 10, §§9–1102–1106 and effective-date clause.
The later inspection deadline is not permission to postpone equipment requirements. Walk the actual exit path from every sleeping area, update the diagram when the layout changes, and retain device production dates. These practical records help identify work to finish before guests arrive.

Baltimore: primary residence, renewal lead time and no transfer
Baltimore Code Article 15, Subtitle 48 generally limits a new STR license to the owner’s permanent residence: at least 180 days of annual residence and the owner’s usual place of return, supported by the listed documents. The historical exception for an additional unit has ownership, booking-history and original filing conditions; it is not a new investor-license window.
- License first: platform-facilitated stays of fewer than 90 consecutive days need the city license, and listings must display its number.
- Renew before the anniversary: the term is two years, but the renewal application and required fee must reach the Housing Commissioner at least 30 days before expiry.
- Budget the right fee: the code sets a $200 biennial fee per dwelling, subject to the City Fee Policy. Confirm the current invoice before filing.
- A sale ends transferability: §48-7(a)(3) expressly says the license does not transfer on sale or any other ownership transfer. A buyer must resolve a new approval before accepting the seller’s bookings.

Keep building, fire, health and zoning compliance separate from licensing. The former FAQ link no longer resolves, so do not rely on its older inspection statement to bypass Maryland’s October 2026 safety law. Ask DHCD about host-presence conditions and direct-only bookings for the exact model; the code’s platform definition does not establish a general direct-booking exemption.
Montgomery County: residence and ADU checks come first
Under zoning §3.3.3.I, an eligible rental must be the owner’s or owner-authorized resident’s primary home. When that resident is absent, the limit is 120 days per calendar year; when present and occupying it, that annual limit does not apply.
The code limits adult overnight guests to six, with bedroom limits, and generally requires one off-street parking space per rental contract unless the listing prohibits vehicle parking. Confirm capacity under both the zoning and housing provisions.

The county FAQ identifies municipalities outside its STR licensing law, including Rockville and Gaithersburg. Confirm the relevant municipal program before submitting a county application. An excluded municipality is not an unregulated area.
Source: DHCA short-term rental FAQ and municipal exclusions.
County STR licenses are annual. The fee page checked for this guide still labels its $500 STR amount as FY26, effective July 1, 2025. Ask DHCA for the current FY27 charge rather than treating that older fiscal label as a verified October 2026 quote.
Ocean City: distinguish rental and STR licenses
Ocean City’s current rental hub requires an annual rental license and Noise Control Permit before renting for any duration. Renting for 30 consecutive days or fewer also requires the STR housing-unit license. The posted single-family example totals $246: $196 rental/Noise Control Permit plus $50 STR fee.
- Check zoning first: ask about the current R-1 or MH rules, any applicable restriction on new licenses, minimum stays and the address’s existing status.
- Count lawful bedrooms: unpermitted attic or garage conversions do not increase approved occupancy.
- Plan inspections and renewals: new licenses must schedule an inspection within 30 days. Open code violations prevent renewal.
- Before closing: have the town confirm buyer licensing, approved capacity and unresolved violations. The seller’s booking calendar is not approval evidence.

The hub links changing district rules and older ordinance materials. This guide does not treat a first-reading proposal or historical moratorium as proof of present license availability. Get a current address-specific answer before promising an opening date or buying furnishings.
State tax and local room tax need separate records
Maryland’s general sales/use tax rate is 6%; local lodging taxes are additional where imposed.
Source: Maryland Tax–General §11–104.
Maryland treats transient accommodations as taxable sales. The Comptroller’s accommodation guidance makes providers responsible for direct sales and intermediaries responsible for the full taxable charge they sell, including their markup and fees. Preserve the documentation supporting who collected and remitted.
Platform booking
Retain the tax detail, platform statement and any applicable resale documentation. Match the state tax and each local tax by name; a combined “tax” line cannot establish coverage.
Direct booking
Register and handle the provider’s tax obligations. Determine the taxable base, stay-length treatment, rate and return schedule with the Comptroller and local collector before taking payment.
Source: Comptroller accommodation sales-tax alert, including provider and intermediary duties.
Do not assume a 30-day stay makes every Maryland tax disappear: the state guidance has a resort-area exception for rentals of four months or less. Montgomery County separately taxes stays of 30 days or fewer and requires returns by the last day of the following month.

Worcester County’s room tax rose to 6% on January 1, 2026. Its current page requires monthly reports due on the 21st for the preceding month and separates room-tax payment from state sales tax. Confirm platform coverage with the Treasurer.

Future collection change: the Comptroller’s April 2026 session review says centralized hotel-tax collection for STR intermediaries was delayed to July 1, 2028. Older statute displays showing July 2027 should not be used to stop present local filings.
Build a safety and approval file before opening
Use the free worksheet to separate tasks already due from later inspection milestones, record the office that regulates the parcel, and list the tax collector for each booking channel.
Open the Maryland readiness worksheet- Assumed equipment quote
- $350
- Assumed corrective electrical work
- $650
- Safety-work cash subtotal
- $1,000
Original scenario: $350 + $650 = $1,000. Neither input is an observed price or required fee. Add actual license, inspection, insurance and furnishing costs separately; do not count the same invoice twice.
A cheap purchase can still require a different operating model. If primary-residence rules exclude the planned whole-home business, compare a legally permitted longer-term use with the rental property calculator using its own rent and expenses.
Maryland hosting questions and next steps
Does the state safety law replace local permits?
No. It expressly preserves local authority. Complete the safety work and obtain the approvals required for the parcel and operating model.
Does a Baltimore unhosted listing prove a new buyer can host?
No. The city’s published new-license route is hosted. Ask DHCD for a written determination about the proposed owner and license before relying on a seller’s history.
Can a Montgomery County ADU be used for weekend rentals?
The cited zoning provision prohibits this STR use on a site with an ADU. Ask the zoning office to review the actual site and any municipal jurisdiction.
For nearby properties across the District line, use the separate DC licensing and night-limit guide; crossing into Virginia changes the local and tax checks again. Return to the state laws directory for other locations.
For a property across Maryland’s western or Potomac boundary, compare West Virginia’s Jefferson County approvals and Harpers Ferry guest-parking checks. Resolve the actual state and municipal boundary before applying either checklist.
