Recording Law for Employers & Businesses in Maryland

Maryland’s wiretap law splits recordings into two categories. If you capture a phone call or text/email, you must get every participant’s consent first — no exceptions. That’s because the law treats phone calls and electronic messages as "wire" or "electronic" communications, which are protected regardless of where or how they happen. For in-person conversations, the rule depends on whether the chat is a "private conversation." Maryland’s statute defines an "oral communication" as "any conversation or words spoken to or by any person in private conversation" — a phrase courts then interpret using the Katz reasonable-expectation-of-privacy (REOP) test to determine whether the conversation qualifies as private. If the conversation is private, you need all parties’ consent to record. If it’s not private — like a loud argument on a public sidewalk or a trooper’s commands during a roadside stop — no consent is required. The key is the "reasonable expectation" test: would a reasonable person in that situation expect the conversation to stay private? If yes, record only with consent. If no, you can record freely. This applies to smartglasses just like any other recording device. The statute is Maryland Courts & Judicial Proceedings §§10-401 to 10-414, with the core prohibition and all-party-consent rule at §10-402(a) and §10-402(c)(3).

Maryland courts use a two-part test to decide if an in-person conversation is "private" enough to require consent. First, did the speaker actually expect privacy? Second, would society recognize that expectation as reasonable? The classic example is Malpas v. State, where a Maryland appeals court ruled that Richard Craigie’s loud, profane rant inside his own apartment — audible through a shared wall to someone in the next unit and recorded on a handheld cassette recorder by defendant Malpas — wasn’t private because the volume made it "the functional equivalent of statements knowingly exposed to the public." So location alone doesn’t matter: a conversation in someone’s home, office, or even a restaurant booth can still be public if it’s loud enough for others to overhear naturally. Quiet chats in a closed room are private. Shouting in a park or on a street is not. The statute itself just says "any conversation or words spoken to or by any person in private conversation," leaving courts to fill in the meaning with the Katz test. Maryland’s highest court has also recognized the REOP gate in Agnew v. State, 461 Md. 672, 197 A.3d 27 (2018), cited by secondary sources for the proposition that the Act protects only conversations in which parties have a reasonable expectation of privacy. The bottom line: if you can overhear the conversation without straining, it’s likely not private, and you don’t need consent to record. Maryland courts have held that wire communications (telephone calls) are protected regardless of a case-by-case REOP showing, so phone calls are always private and require consent.

There’s an unreported trial-court decision, State v. Graber, where a Maryland judge dismissed wiretap charges against a driver who recorded a state trooper during a public traffic stop. The judge ruled the trooper had no reasonable expectation of privacy in statements made during a public roadside stop. But this is only persuasive authority, not binding law, and it applies narrowly to outdoor, public roadside stops. It doesn’t clearly cover indoor police encounters, conversations between officers away from the public eye, or stops on private property. Because Maryland’s wiretap law carries felony penalties for violations, treat police-present conversations as private unless the encounter is clearly outdoors on a public roadway with no signs of seclusion. If the setting is ambiguous — like a doorway, parking lot, or inside a business — require consent or get legal review before recording. The Fourth Circuit has also recognized a First Amendment right to record police performing their duties in public in Sharpe v. Winterville Police Dep’t, 59 F.4th 674 (4th Cir. 2023), which aligns Maryland’s circuit with the broader trend among federal appellate courts. The statute remains §§10-401 to 10-414, with the core prohibition and all-party-consent rule at §10-402(a) and §10-402(c)(3). Maryland has no statutory exception permitting citizens to record on-duty officers without consent as such; instead, case law holds that officers conducting their public duties generally lack a reasonable expectation of privacy in their on-the-job statements, so the encounter falls outside the definition of a protected "oral communication" altogether.

Maryland’s wiretap law only restricts the interception of "oral communications" — meaning spoken words. If your smartglasses capture only video with no audio, the law doesn’t apply at all. The moment you add audio to the video, the all-party consent rule kicks in if the conversation is private. So silent video surveillance is unrestricted. Audio capture triggers the law’s protections if the conversation is private. This means you can use smartglasses for silent documentation, but if you enable audio recording, you must ensure either that the conversation isn’t private or that you have everyone’s consent. The statute’s definitions in §10-401 make this clear: "oral communication" refers to spoken words, not images. Maryland courts have held that wire communications (telephone calls) are protected regardless of a case-by-case REOP showing, so phone calls are always private and require consent.

Recording a private conversation without consent is a felony in Maryland, punishable by up to five years in prison and a $10,000 fine under §10-402(b). Even if you don’t face criminal charges, the person you recorded can sue you for civil damages — at least $100 per day of violation or $1,000, whichever is higher, plus attorney’s fees under §10-410. These penalties apply whether you’re an employer recording employees or a business recording customers. The law is strict, and courts don’t look kindly on technical violations. The only exception is if you’re recording for a lawful purpose and the conversation isn’t private — but that’s a fact-specific judgment best made with legal advice. Maryland’s penalty structure is mixed: felony penalties apply to interception offenses under §10-402(b), while lesser misdemeanor-level fines and imprisonment apply to certain related offenses such as unlawful divulgence under §10-402(d) and reduced penalties for certain radio-communication first offenses under §10-402(e).

Imagine an employee wears smartglasses with audio enabled while assisting a customer in a quiet corner of a retail store. The customer speaks softly about a sensitive issue, like a medical condition or financial concern. Because the conversation is quiet and in a semi-private area, a reasonable person would expect it to stay private. Under Maryland law, recording this conversation without the customer’s consent violates the wiretap statute. The employer could face a civil lawsuit or even criminal charges. If the employee instead uses the glasses to record only video with no audio, there’s no violation. If the conversation happens in the middle of the sales floor where others can easily overhear, the law treats it as public, and no consent is needed — but the employer should document why they believe the conversation was public before enabling audio. Maryland courts have held that wire communications (telephone calls) are protected regardless of a case-by-case REOP showing, so phone calls are always private and require consent.

Maryland has no express statutory carve-out for recording inside one’s own home. Location is not dispositive — courts apply the same Katz-derived reasonable-expectation-of-privacy analysis regardless of where the speech occurs. In Malpas v. State, a third-party witness (Craigie) speaking loudly in his own apartment lost wiretap protection; his shouted statements, audible through a shared wall and recorded by the defendant on a handheld cassette recorder, were held to be "the functional equivalent of statements knowingly exposed to the public," so no REOP existed despite Craigie being in his own home. The court held he had no reasonable expectation of privacy despite being in the home. So being in one’s own home raises the likelihood a REOP exists but does not guarantee it, and does not itself trigger a stricter or separate rule; the general all-party-consent/oral-communication-privacy framework of §§10-401/10-402 still governs. Workplace conversations follow the same REOP analysis: a private office meeting is protected, while loud speech in a factory floor or open-plan workspace may not be. Public settings like sidewalks, parks, and transit platforms generally lack REOP, but semi-private spaces within those areas (e.g., a quiet corner of a café or a store aisle) may still qualify depending on volume and observable seclusion. Maryland courts have held that wire communications (telephone calls) are protected regardless of a case-by-case REOP showing, so phone calls are always private and require consent.

Electronic communications such as text messages and emails are treated the same as phone calls under Maryland’s wiretap law. They are "electronic communications" as defined in §10-401(5) and are protected per se, requiring all parties’ consent to intercept regardless of any reasonable-expectation analysis. This means recording or intercepting electronic communications without consent is unlawful even if the conversation occurs in a public setting or involves no expectation of privacy. The statute’s all-party-consent requirement applies to these communications just as it does to wire communications, and violations carry the same felony penalties under §10-402(b).
