Thinking about converting a Boston rental into condominiums? You are not alone. Condo conversions can unlock value, diversify exit options, and attract a wider buyer pool. They also come with a specific set of rules in Boston that you need to understand before you start. In this guide, you will learn how the process works, what a Conversion Plan and Permit typically involve, how tenant protections factor into your timeline and budget, and the practical steps to keep your project moving. Let’s dive in.
Boston’s framework: state law plus local rules
Condo conversions in Boston sit on two layers of law. First, Massachusetts state law, commonly known as the Massachusetts Condominium Act (M.G.L. c. 183A), lays out how condominiums are created and recorded. Second, Boston’s municipal rules govern the local conversion process, including plan submission, permits or approvals, and tenant protections.
In practice, you should expect to work with Boston’s municipal departments, often including Inspectional Services, for plan submission and review. The city’s procedures, forms, and fees can change, so plan to confirm the current steps directly with the appropriate Boston office before you file.
The Conversion Plan and Permit
Before you market or sell units separately, Boston commonly requires a formal submission and approval. While the exact name of the approval can vary, investors typically prepare a Conversion Plan and apply for a permit or city approval. Treat pre-application conversations with the city as time well spent.
What your plan should cover
Your Conversion Plan should be clear, complete, and consistent with state recording requirements. Expect to include:
- Building facts: address, owner of record, current occupancy, number of units, and a description of common areas.
- Unit details: proposed unit divisions, square footage, floor plans, and unit numbers.
- Common elements and allocations: parking, storage, and how you will allocate condominium assessments.
- Governance documents: draft master deed, declaration, bylaws, initial budget, and estimated common expenses for each unit.
- Construction scope: planned renovations, code updates, and timeline.
- Tenant information: current leases, rent roll, security deposits, occupancy, and your notice and relocation plan.
- Compliance: confirmation that the property meets applicable zoning and building codes, and that required disclosures will be provided.
- Authorization: certification that you have authority to convert, and any signatures or legal opinions the city may require.
How city review usually works
A practical sequence looks like this:
- Hold a pre-submission consultation with the applicable city office to clarify forms, fees, and required content.
- Submit your plan and pay any required fees.
- Respond to requests for clarification or additional documentation during the administrative review.
- Complete any public notice or posting requirements if the city requires them.
- Obtain a Conversion Permit or written approval. Only then should you proceed toward marketing or sales consistent with the city’s conditions and state recording rules.
Tenant protections you must plan for
Tenant protections are central to Boston’s approach. They shape your notices, schedule, and budget.
Required notices
You should plan to deliver advance written notice to each tenant about your intent to convert and their rights. The form, content, and timing of these notices are set by municipal rules. Notices typically explain the conversion plan, where documents can be reviewed, tenant rights, and potential timelines. Make sure the delivery method and proof of service meet the city’s requirements.
Purchase options and relocation assistance
Some municipalities provide tenants with opportunities to purchase their unit when a building converts. Others require relocation payments or assistance for tenants who are displaced. In Boston, confirm whether tenants have any purchase rights, who qualifies for relocation assistance, how payments are calculated, and how and when payments must be delivered. Build these obligations into your budget and schedule.
Lease and tenancy interaction
Conversion does not erase leases. Fixed-term leases typically remain in effect until they expire. For month-to-month tenants, separate municipal rules may set required notice windows. Plan your conversion schedule around actual lease terms and city timelines.
The step-by-step process and timeline
Every property is different, but a well-planned conversion follows a predictable rhythm. Use these steps as a framework and confirm timing with the city and your attorney.
Timeline overview
- Pre-transaction due diligence: 2 to 8 weeks
- Title search and lien clearance, zoning checks, building code review, and a full tenancy audit.
- Draft conversion documents: 4 to 12 weeks
- Prepare the master deed, declaration, bylaws, budget, and unit plans with your attorney and architect.
- Submit plan and apply for approval: city review often 4 to 12 weeks
- Timing depends on completeness, departmental workloads, and any required public notices.
- Tenant notice period: varies by municipal rule
- Confirm exact notice timing, content, and delivery method with the city.
- Renovations and code work: 1 to 12 months or more
- Scope depends on building condition and planned upgrades.
- Recording and sales: sequence depends on permit conditions and state requirements
- Record the master deed and proceed with unit deeds and closings at the Suffolk County Registry of Deeds.
Overall, many conversions run 3 to 12 months from plan development to first closings, and complex projects can extend to 12 to 24 months.

Post-conversion
- Transfer ownership of units and update association records.

Your core team
Build a team that knows Boston’s process and Massachusetts law. At a minimum, plan to work with:
- A Massachusetts real estate attorney experienced in condo conversions.
- A title company or attorney for title work and recording.
- An architect or engineer for unit plans and code compliance.
- An appraiser or market specialist to inform pricing and assessments.
- A relocation consultant if assistance obligations are complex.
- An accountant for budgeting and condominium association setup.
- A real estate broker with Boston condo sales expertise.
- A building code consultant or inspector to plan upgrades and compliance.
Costs to budget
Every project is unique, but common costs include legal fees for drafting and filings, architectural and engineering work, municipal filing fees, recording fees at the Registry of Deeds, relocation assistance if required, renovation and code compliance, and marketing and brokerage for unit sales. Since city fees and relocation requirements can change, verify amounts directly with Boston’s offices before you finalize budgets.
Common pitfalls to avoid
- Missing or mishandling tenant notices. Improper notice can derail your schedule or create liability.
- Overlooking relocation obligations or possible tenant purchase rights.
- Recording errors in the master deed or unit descriptions that create title issues.
- Underestimating the time and cost to bring the building up to code.
- Assuming tenants will vacate on your timeline. Lease terms and protections control.
- Delaying attorney and title involvement until late in the process.
Practical next steps
- Confirm the current Boston forms, filing procedures, and fees with the appropriate city office.
- Retain a Massachusetts real estate attorney familiar with M.G.L. c. 183A and Boston’s conversion rules.
- Order title work, review zoning, and complete a full tenancy and code audit.
- Build your plan, documents, and budget, including tenant notice and any relocation strategy.
- Schedule a pre-submission conversation with the city and finalize your Conversion Plan for filing.
