A Homeowner's Guide to Somerville Tree Service Regulations
Tree Service Somerville
Navigating tree care in Somerville, Massachusetts, requires understanding the city’s comprehensive Tree Preservation Ordinance. Whether you’re planning tree removal near Davis Square or maintaining your property’s urban canopy around Assembly Row, knowing local regulations can save you from costly fines and legal complications.

Understanding Somerville’s Tree Preservation Ordinance
The city takes tree protection seriously, implementing one of the most comprehensive tree ordinances in Massachusetts. All trees, on public or private property, require a permit to be removed. The current ordinance, which went into effect in 2019, significantly expanded protections beyond just public trees to include private property regulations.
Key Requirements for Tree Removal
Any tree measuring more than eight inches in diameter at breast height (DBH) – measured 4.5 feet from the ground – falls under permit requirements. This applies to all non-invasive tree species throughout Somerville, from the historic neighborhoods near Tufts University to the bustling commercial areas around Davis Square.
Property owners must replace removed trees with equivalent caliper inches or make a payment to the city’s Tree Fund. The payment amount is $600 per caliper inch as of August 2024. For homeowners living in properties with three units or fewer, while permits are still required, the replanting or payment requirements may be waived.
When You Need Professional Tree Service
Finding a qualified tree service becomes crucial when dealing with Somerville’s strict regulations. Professional arborists understand local requirements and can help navigate the permit process effectively.
Emergency Situations
Trees determined to be hazardous due to danger to public health or safety, threats to life or property, or severe damage during emergencies don’t require permits for removal, but need authorization from the Tree Warden. Contact the Tree Warden at trees@somervillema.gov or call 311 for immediate authorization.
Exceptions to Permit Requirements
Not all tree removals require permits. Trees under eight inches DBH and invasive species can be removed without permits. Dead, dying, or hazardous trees also qualify for expedited removal with proper authorization from city officials.
Working with Somerville Tree Masters and Local Regulations
When searching for tree service near me in Somerville, partnering with knowledgeable local companies ensures compliance with city regulations. Professional tree service providers understand the nuances of local ordinances and can guide homeowners through the proper channels.
The Permit Application Process
Property owners must personally submit permit applications – landscapers or arborists cannot apply on their behalf. Applications require detailed plans showing which trees will be removed and proposed replacement plantings. The city’s Urban Forestry Committee reviews applications and may recommend waivers for financial hardship or other circumstances.
Working Around Local Landmarks
Tree care considerations vary depending on your property’s location within Somerville. Properties near Davis Square, with its vibrant commercial district and Red Line accessibility, often have different considerations than those near Assembly Row’s modern developments. The city’s Tree Warden and Urban Forestry Committee consider neighborhood characteristics when reviewing permits.
Heritage Trees and Special Protections
Somerville designates certain trees as “Significant Trees” or heritage trees based on age, species, health, community meaning, and historical importance. These trees require Special Permits for removal, with additional requirements for replacement or Tree Fund payments.
Significant Tree Criteria
The City Arborist designates trees as significant based on multiple factors, including ecological value, historical importance, and aesthetic contribution to the community. Properties throughout Somerville, from the academic neighborhoods near Tufts to the family-friendly areas around Ball Square, may contain these protected specimens.
Tree Maintenance and Pruning Regulations
Beyond removal, tree maintenance also falls under city oversight. Regular pruning and care help maintain tree health and can prevent the need for emergency removal. Professional tree service providers understand proper pruning techniques that comply with city standards while maintaining tree health.
Preventive Care Programs
Somerville actively manages threats to its urban forest, including the Emerald Ash Borer prevention program. The city treats healthy ash trees with TreeAzin injections every two years and removes trees only when necessary. Property owners should coordinate with city programs when planning ash tree care.
Enforcement and Penalties
Violating Somerville’s tree ordinance carries significant consequences. Destroying or damaging trees in Somerville is taken very seriously and is subject to fines. Work performed without proper permits results in immediate stop-work orders, and violations can result in substantial financial penalties.
Compliance Best Practices
Before beginning any tree work, consult with qualified tree service professionals who understand local regulations. Document tree conditions with photographs, especially for emergency removals, and maintain communication with the Tree Warden’s office throughout the process.
Replacement Requirements and Tree Fund
When removing permitted trees, property owners have three options: plant replacement trees equaling the removed tree’s caliper, pay into the Tree Fund, or combine both approaches. Replacement trees must conform to city standards and be planted on the same or adjacent properties.
Tree Fund Contributions
Tree Fund payments support Somerville’s urban forestry initiatives, including new plantings in parks and public spaces throughout the city. These contributions help maintain the urban canopy that benefits neighborhoods from Davis Square to Assembly Row.
