Learn about the Condominium and Cooperative Conversion Ordinance, and what it means for landlords and tenants.

About the ordinance

On March 8, 2021, the City of Boston amended the Condominium and Cooperative Conversion Ordinance (the “Conversion Ordinance”) of 1999. The ordinance applies to any residential property built before December 1983 that has four or more rental units, where the owner intends to convert the property to a residential condominium or cooperative use. This would be done either through:

  • the conversion of the existing units, or
  • through the demolition of the current units and replacement of them with a new condominium or cooperative building.

The ordinance requires that tenants be provided notice of the intent to convert. The notice informs tenants of the rights and benefits they have in a conversion. All tenants have certain rights. Tenants who meet certain eligibility requirements have additional rights. Tenants eligible for additional rights are those who are:

Conversion Process

The conversion process begins as soon as the owner forms an intent to convert the property to a condominium or cooperative. The owner must immediately provide tenants a one-year notice. 

The ordinance requires any landlord planning to convert a property with four or more residential units into condominiums or a cooperative to secure a:

  • Conversion Plan from the Mayor's Office of Housing, and
  • Conversion Permit from the Inspectional Services Department.

Fees for the Conversion Plan and Permit are $1,000 per unit, payable to the City of Boston, upon applying for a Conversion Plan.

Landlord Application for a Conversion Plan

Landlords must apply to the Mayor's Office of Housing for a Condominium or Cooperative Conversion Plan, even if all the units are vacant. The landlord must submit an application within one month of notifying tenants of the intent to convert.
