Being a landlord in Massachusetts comes with rights—but also serious responsibilities. While many rental property owners manage just fine on their own, others unintentionally violate laws that can lead to fines, lawsuits, or even forced tenant reinstatement.
If you own or manage rental property in Lynnfield or the surrounding area, understanding the legal pitfalls of landlord-tenant relationships is essential. Here are five common mistakes landlords make—and how an experienced lawyer for landlords can help you avoid them.
1. Mishandling Security Deposits
Massachusetts has some of the strictest rules in the country when it comes to collecting, holding, and returning security deposits.
Common mistakes include:
- Failing to provide a written receipt and separate bank account
- Not paying annual interest on the deposit
- Making deductions without proper documentation
- Returning the deposit too late—or not at all
Landlords who violate these laws can be ordered to return triple the deposit amount, plus legal fees. A lawyer helps ensure your deposit process is 100% compliant with state security deposit laws, so you don’t pay for a technical error.
2. Using an Illegal or Incomplete Lease Agreement
Many landlords download generic leases online or reuse outdated templates. Unfortunately, those agreements often include unenforceable terms—or leave out key clauses altogether.
A legally sound lease should include:
- Start and end dates
- Rent amount and due date
- Maintenance responsibilities
- Rules around entry, guests, and subletting
- Dispute resolution terms
- Proper notices and signatures
At Zaheer Law, we draft and review rental agreements to ensure they protect landlords and comply with Massachusetts housing law. You can learn more about this on our Landlord-Tenant Law service page.
3. Improperly Serving Notices or Filing for Eviction
Evictions in Massachusetts require strict adherence to notice requirements, timelines, and court procedures. One mistake can result in a case dismissal—even if you’re legally in the right.
Some common errors:
- Serving the wrong type of notice (e.g., 14-day vs. 30-day)
- Filing eviction before the notice period ends
- Failing to properly document lease violations
- Attempting “self-help” eviction (e.g., changing locks)
Whether it’s a no-fault eviction or one based on nonpayment, a landlord-tenant attorney can prepare the correct notices, file in the appropriate court, and represent you through the Housing Court process.
4. Failing to Address Habitability Issues Promptly
Landlords are legally obligated to maintain rental units in a habitable condition. This includes functioning heat, electricity, plumbing, and overall safety.
If tenants report:
- Mold or pest infestations
- No heat during winter months
- Structural damage or water leaks
- Unsafe stairs or faulty locks
You must act quickly. Ignoring these issues not only jeopardizes tenant health—it may give them the right to withhold rent or break the lease.
In serious cases, you could be fined or ordered to pay damages. Having legal counsel ensures you understand the urgency of certain complaints and how to respond correctly and promptly.
5. Not Documenting Communications or Inspections
Verbal agreements, casual repairs, or unlogged visits can come back to haunt landlords in legal disputes. Without documentation, it’s your word against the tenants.
A lawyer will advise you to:
- Keep written records of all notices, agreements, and complaints
- Confirm communications in writing (text or email is fine)
- Document inspections with time-stamped photos or signed reports
- Use certified mail for formal notices when required
These practices protect you if the situation escalates—and they’re especially important if the dispute goes to Housing Court.
A Landlord Lawyer Isn’t Just for Lawsuits
