Anne Arundel County and Maryland's New STR Safety Act: What Hosts Must Do by October 2026

Executive Summary

• State Safety Act Effective October 1, 2026: Maryland's Jillian and Lindsay Wiener Short-Term Rental Safety Act now requires evacuation diagrams, working fire extinguishers, and interconnected smoke and carbon monoxide alarms in every STR unit offered for fewer than 30 consecutive days.
• Platform Compliance: Booking services must notify hosts and collect compliance documentation — a platform-level enforcement mechanism that shifts verification upstream.
• County Inspection Mandate: Every county must complete annual fire-safety inspections of short-term rentals by July 1, 2028, creating a compliance runway operators should prepare for now.

Maryland's Statewide Safety Requirements

The Wiener Short-Term Rental Safety Act (Chapter 9 of 2026) applies to any unit offered for fewer than 30 consecutive days anywhere in Maryland. It layers safety requirements on top of whatever local licensing regime a county or municipality already has in place.

What Hosts Must Provide

Evacuation diagram and emergency numbers — Every property must have a posted evacuation diagram and emergency contact numbers displayed inside the unit, visible to guests. This is a physical posting requirement, not a digital disclosure in the listing.

Working fire extinguisher — At least one functional fire extinguisher must be present and accessible in the unit.

Smoke and carbon monoxide alarms — All alarms must be working, interconnected where required by code, and replaced if non-functioning, over ten years old, or undated. This is a higher bar than many hosts currently meet — the interconnection requirement means a single battery-operated detector in a hallway may not suffice if the property's layout or code classification requires interconnected units.

Platform Enforcement

The act requires booking platforms to notify hosts of these requirements and collect compliance documentation. This means Airbnb, Vrbo, and other platforms operating in Maryland will need to verify that listed properties have documentation on file confirming evacuation diagrams, fire extinguishers, and alarm compliance. Hosts who cannot produce this documentation risk delisting.

Inspection Timeline

Counties have until July 1, 2028 to implement annual fire-safety inspections of short-term rental properties. This two-year runway gives local governments time to build inspection capacity, but the inspections themselves will be annual once they begin. Operators should treat the current period as preparation time, not a grace period for ignoring the safety requirements.

Anne Arundel County's Local Framework

Anne Arundel County operates its own licensing and tax regime on top of the state requirements, creating a layered compliance environment.

Registration

Short-term rentals require registration with the Department of Inspections and Permits at $100 for a two-year term. The registration is property-specific and non-transferable — a sale triggers a new registration requirement for the buyer. Hosts may register no more than two dwelling units, with ownership stakes in entities counting toward the cap.

Tax Stack

Anne Arundel County operators navigate a segmented tax structure:

Late tax payment carries a 10% penalty plus 0.5% monthly interest. Failure to register for the county tax triggers a $1,000 civil penalty. These are not theoretical — the county actively enforces them.

Enforcement Penalties

Violations of the short-term rental code are Class C civil offenses: $500 for a first violation and $1,000 for each subsequent violation. Each day a violation continues counts as a separate offense, meaning an unregistered property operating for a month could theoretically accumulate $30,000 in penalties before anyone files a court action.

Annapolis: The 10% Blockface Cap

The City of Annapolis operates a separate STR regime within Anne Arundel County. Its most significant provision is a 10% cap on units per blockface — no new licenses are issued on any block that has already reached the threshold. Existing licenses may renew only through November 2027, after which a reduction lottery begins. This is a hard supply constraint with no grandfathering path for new entrants once a block hits its cap.

Combined with the $5,000 per-violation fines Annapolis proposed in September 2026, the city now has both supply-side caps and demand-side deterrents in place.

Investor Due Diligence Takeaway

Maryland operators face a compliance clock that is already running. The state safety requirements are effective now — not pending, not proposed. Hosts who have not posted evacuation diagrams, verified alarm interconnection, and placed fire extinguishers are currently out of compliance. The platform documentation requirement means this will surface at listing renewal or verification cycles, not just at inspection. Anne Arundel County's $500-per-day violation structure and Annapolis's $5,000 fines make the cost of inaction steep.
