Massachusetts burglary laws define the crime narrowly: breaking and entering a dwelling at night with intent to commit a felony inside. Everything else that sounds like burglary — daytime break-ins, warehouses, cars, offices — is charged under the separate breaking-and-entering statutes. The distinction matters because true burglary carries some of the heaviest penalties in the state’s criminal code, up to life in prison when a weapon or an assault is part of the offense.
What Counts as Burglary
Burglary in Massachusetts is governed by Sections 14 and 15 of Chapter 266. Three elements have to line up: the place must be a dwelling, the time must be nighttime, and the person must have entered with intent to commit a felony.1General Court of Massachusetts. Massachusetts General Laws Chapter 266 Section 14
A “dwelling” is a place where people live or sleep. That includes attached structures like a garage and temporary residences used as living quarters. A commercial building, a warehouse, a shed detached from a home, or a vehicle is not a dwelling for this purpose, and a break-in at any of those falls under a different statute.
“Breaking” is broader than most people assume. Smashing a window or forcing a door obviously counts, but so does opening an unlocked door, pushing up a window, or turning a doorknob to get in without permission. Massachusetts also recognizes constructive breaking, where the defendant talks or tricks their way inside through fraud, threats, or deception. “Entry” is satisfied the moment any part of the body crosses the threshold. An arm reached through an open window to grab something inside is enough.
The intent element is where many cases turn. The prosecution has to show the defendant meant to commit a felony inside at the moment of entry, not that the idea occurred to them later. Intent is usually proven by circumstantial evidence: burglary tools, prior statements, a targeted location.
How Massachusetts Defines Nighttime
Because burglary requires a nighttime offense, the statute defines the term precisely. Nighttime begins one hour after sunset and ends one hour before sunrise, measured by the average time at that location and season.2Massachusetts Trial Court. Instruction 8.100 – Breaking and Entering in the Nighttime It is not simply whether it was dark outside. A break-in at 5:30 a.m. in July, when the sun rises early, could fall outside the nighttime window even though it feels like the middle of the night.
If the clock puts the offense outside that window, the case cannot be charged as burglary. It becomes a daytime breaking-and-entering offense instead, which carries meaningfully lower exposure.
Penalties for Armed Burglary
Section 14 covers the most serious version of burglary. If the person was armed with a dangerous weapon, armed themselves while inside, or assaulted anyone lawfully present in the dwelling, the sentence is life in state prison or any term of not less than 10 years.1General Court of Massachusetts. Massachusetts General Laws Chapter 266 Section 14
Firearms raise the floor sharply. Armed burglary committed while carrying a firearm carries a mandatory minimum of 15 years. A second firearm-related burglary conviction carries a mandatory minimum of 20 years.1General Court of Massachusetts. Massachusetts General Laws Chapter 266 Section 14 A repeat offender sentenced under Section 14 cannot receive a suspended sentence or probation.
Penalties for Unarmed Burglary
Section 15 applies when someone breaks into a dwelling at night with felonious intent but is not armed and does not assault anyone inside. The maximum sentence is 20 years in state prison.3General Court of Massachusetts. Massachusetts General Laws Chapter 266 Section 15 A prior conviction under either Section 14 or Section 15 raises the minimum to 5 years.
When the Charge Is Breaking and Entering Instead
If any of the three burglary elements is missing, the conduct is usually charged under one of the breaking-and-entering statutes in Sections 16 through 18. These remain serious felonies, but the exposure is lower.
Section 16 covers nighttime breaking and entering of a building, ship, vessel, or vehicle that isn’t a dwelling, when the intent is to commit a felony. Maximum sentence: 20 years in state prison or up to two and a half years in a house of correction.4General Court of Massachusetts. Massachusetts General Laws Chapter 266 Section 16
Section 17 covers daytime breaking and entering, or nighttime entry without an actual breaking, when someone lawfully inside is put in fear. Maximum sentence: 10 years in state prison. If a firearm was involved, a 7-year mandatory minimum applies.5Mass.gov. Massachusetts General Laws c266 Section 17
Section 18 covers the same conduct as Section 17 when nobody inside is put in fear. Maximum: 10 years in state prison, or a fine of up to $500 and up to two years in jail.6General Court of Massachusetts. Massachusetts General Laws Chapter 266 Section 18 A firearm again triggers a 7-year mandatory minimum.
Common Defenses
Burglary cases have multiple moving parts, and the strongest defense usually attacks whichever element is weakest in the prosecution’s proof.
Lack of Felonious Intent
Because burglary requires intent to commit a felony at the moment of entry, this is the most frequently contested element. Entry while heavily intoxicated, entry into the wrong unit, or entry for a non-criminal purpose may not supply the intent the statute demands. The prosecution needs real evidence of what the defendant planned to do inside, not just the fact that they were somewhere they shouldn’t have been.
Authorized Entry
If the defendant had permission to enter, or reasonably believed they did, the breaking element falls apart. This comes up with estranged family members, former roommates, and people who walked into the wrong apartment.
Challenging the Nighttime Element
If the offense can be placed outside the statutory nighttime window, a burglary charge may have to be reduced to a daytime breaking-and-entering charge under Section 17 or 18. The difference can be decades of prison time.
Suppression of Evidence
Evidence seized in violation of the Fourth Amendment can be excluded. An unlawful search of a car, home, or person that turned up stolen property or burglary tools may be challenged by motion, and a successful motion can collapse the case.
Repeat Offender Exposure
Massachusetts has an aggressive habitual offender statute. Under Chapter 279, Section 25, anyone convicted of a felony who already has two prior felony convictions carrying sentences of at least three years each must be sentenced to the maximum term allowed by law for the current offense.7General Court of Massachusetts. Massachusetts General Laws Chapter 279 Section 25
A harsher subsection applies to defendants with two prior convictions for specified violent or serious crimes, including armed burglary under Section 14 and unarmed burglary under Section 15. A person who qualifies receives the statutory maximum for the current offense and is barred from parole, probation, work release, furlough, and good-conduct reductions.7General Court of Massachusetts. Massachusetts General Laws Chapter 279 Section 25 Because armed burglary has a maximum of life imprisonment, a qualifying habitual offender convicted under Section 14 can be sentenced to life with no path to release.
Statute of Limitations
Burglary charges must be brought within six years of the offense. Chapter 277, Section 63 sets a default six-year window for indictments on any crime not specifically exempted, and burglary is not on the exemption list.8General Court of Massachusetts. Massachusetts General Laws Chapter 277 Section 63 Any period the defendant spends living outside Massachusetts does not count toward the deadline.
What Else a Conviction Costs
Prison time is only part of the picture. Burglary is a felony, and federal law permanently bars anyone convicted of a crime punishable by more than one year of imprisonment from possessing firearms or ammunition.9Office of the Law Revision Counsel. 18 United States Code Section 922 Both armed and unarmed burglary clear that threshold by a wide margin. A convicted felon caught with a firearm faces a separate federal charge carrying up to 15 years, stackable on any state sentence.
A felony record also affects employment, housing, and professional licensing. Background checks are routine. Licenses in fields like healthcare, finance, and education may be denied or revoked. Courts can order restitution for stolen or damaged property, and that financial obligation survives the prison term.
