Find Somerville Sex Offenders
Somerville sex offenders can be found through the state's public registry search tool run by the Sex Offender Registry Board. The city sits in Middlesex County, just north of Boston, and has a population near 80,000. SORB keeps records on all Level 2 and Level 3 sex offenders who live, work, or go to school in Somerville. You can search the registry for free at any time. The Somerville Police Department also has access to registry data and can help with in-person requests. This page covers how to search, what records are public, who must register, and what the law says about sex offenders in Somerville.
Somerville Overview
Search Somerville Sex Offenders Online
The SORB online search portal is the best way to look up sex offenders in Somerville. The tool is run by the Massachusetts Sex Offender Registry Board, and it shows all Level 2 and Level 3 offenders with a Somerville address on file. You can search by name, city, or zip code. The portal does not charge a fee. You do not need to make an account. Just type in the search and the results come up right away. Each result shows the offender's name, home address, a photo, physical traits, and the crime that led to their placement on the registry. Somerville has its own zip codes, so searching by zip is a fast way to narrow results to just the city.
Level 1 sex offenders are not shown in the portal. That is state law. Only Level 2 and Level 3 records are public. If you need to check on a Level 1 offender, that data is not available to the public at all.
SORB updates the portal on a regular basis. When an offender moves into or out of Somerville, the change shows up after SORB processes the new address. You can also call SORB at (978) 740-6400 or use the toll-free line at 1-800-93-MEGAN to ask about a specific person or get help with a search.
Somerville Police and In-Person Access
The Somerville Police Department is at 220 Washington Street, Somerville, MA 02143. You can call them at (617) 625-1212. The police station has access to the full SORB database and can help you look up sex offenders in Somerville if you prefer to ask in person rather than use the web portal. There is no cost for this, and you do not have to give a reason for your request. The records are public.
In-person requests can be useful for older records. Some Level 2 offenders who were classified before July 12, 2013 may not show up in the online search tool. Those records still exist in the SORB system, but they were added before the online portal was fully launched. For those cases, going to the Somerville Police Department and asking at the desk is the best way to get the information you need. An officer can pull the records from the state database while you wait.
Somerville PD also plays a role in community notification for Level 3 sex offenders. When a Level 3 offender moves into a Somerville neighborhood, police may distribute flyers or post public notices. This active notification step is required by state law for Level 3 offenders only. Level 2 offenders do not trigger the same notification process, but their records are still public if you search for them.
The SORB search portal at sorb.chs.state.ma.us lets you search for sex offenders by name or by location, including Somerville and surrounding cities.
Results from the portal include the offender's current address, photo, classification level, and the offense that led to registration.
Classification Levels for Somerville Offenders
Massachusetts uses a three-tier system to classify sex offenders. The Sex Offender Registry Board assigns each person a level after a formal hearing. Level 1 means the lowest risk of re-offense. Level 2 is moderate risk. Level 3 is the highest. The classification is based on the nature of the crime, the person's history, and a risk assessment score that SORB calculates using set criteria.
For Somerville residents looking up offenders, the key thing to know is that only Level 2 and Level 3 records are public. You will not find Level 1 offenders in any search tool or by asking at the police station. The law keeps those records sealed from public view.
Level 3 offenders in Somerville get the most attention. Police are required to actively tell the community when a Level 3 offender moves in. That can mean flyers, door-to-door visits by officers, or notices posted in public places near the offender's address. Level 2 offenders do not get this treatment, but anyone can still look them up through SORB or through the police station at any time.
Who Must Register in Somerville
Any person convicted of a qualifying sex offense under Massachusetts General Laws Chapter 6, Sections 178C through 178Q must register with SORB. This applies to anyone who lives in Somerville, works in Somerville, or attends school in Somerville. The law does not care where the conviction happened. Someone convicted in another state or in federal court still has to register in Massachusetts if they have a connection to Somerville through residence, employment, or education.
The registration timeline is strict. A person leaving prison or a treatment facility must register before release or within two days if they are going to a Somerville address. Someone who moves to Somerville from out of state has three days to register after arriving. The same three-day rule applies when an offender changes their address within the city. Missing these deadlines is a crime on its own.
Note: Failure to register carries up to five years in state prison for a first offense and a mandatory minimum of five years for repeat violations.
Somerville Sex Offender Verification Rules
Registered sex offenders in Somerville must verify their information once a year in person. This is part of state law under Section 178F1/2. The offender goes to the Somerville Police Department and confirms that their name, address, and other details on file are still correct. If something has changed and they did not report it already, they have to update it during the verification visit. Skipping the annual check-in is treated the same as failing to register.
Level 3 offenders may face extra check-in requirements depending on the terms of their classification. Some may need to report more than once a year. SORB sets these conditions at the time of the classification hearing, and they vary from person to person. The Somerville Police Department tracks which offenders are due for verification and follows up if someone does not show up on time.
If a sex offender moves out of Somerville, they must tell SORB within two days of the move. They also have to register with the police department in their new city. Moving without updating the registry is a separate criminal charge that can be prosecuted in addition to any other charges.
Courts Serving Somerville
Somerville falls under the Middlesex County court system for most criminal matters. Sex offense cases involving Somerville residents may be heard in the Somerville District Court or, for more serious charges, in the Middlesex Superior Court in Woburn. The Middlesex County District Attorney's Office handles prosecutions for sex crimes in the county. When someone is convicted and sentenced, SORB gets involved to classify the offender and add them to the registry.
Federal sex offenses are handled by the U.S. District Court for the District of Massachusetts. The Campus Sex Crimes Prevention Act also applies in Somerville because the city has several colleges and university campuses nearby. Sex offenders enrolled at or employed by those schools must notify SORB, and the institutions have to make that information available to students and staff upon request. Somerville's proximity to places like Tufts University makes this federal rule especially relevant for the area.
