FAQ – Frequently Asked Questions


Q: What is the Community Preservation Act?

The Community Preservation Act, M.G.L. c. 44B, (“CPA”) is a Massachusetts law that allows participating cities and towns to create a dedicated fund for important projects that can greatly impact a community’s character and quality of life. Communities raise money locally for the CPA through a small surcharge on property taxes (between 1% and 3%, as selected by the community). In addition to the property tax surcharge, the state provides matching funds between 5% and 100% of the funds raised by the community.

The Community Preservation Act was adopted by Medford voters on November 3, 2015. The act established a local dedicated fund, financed by a voter-approved property tax surcharge of
1.5%, and matching funds from the statewide CPA Trust Fund, to invest locally in open space, historic preservation, outdoor recreation and community housing projects.

Q: Where does the money come from for CPA projects?

The money comes from a combination of 2 sources:

  1. Medford residents pay a 1.5% surcharge on a portion of their annual property taxes. In the first year, the CPA surcharge generated approximately $1.2M. Medford’s ordinance exempts the first $100,000 of residential or commercial property value from the surcharge, and offers an additional exemption for “low income households”, or “moderate income seniors” as defined by Section 2 of the Community Preservation Act. In 2017, Medford homeowners paid an average of $47.69 per year for the CPA surcharge.
  2. The Massachusetts CPA law creates a Statewide Community Preservation Trust Fund which provides distributions each year to communities that have adopted CPA. The Trust Fund’s revenues are derived from fees collected at the Registry of Deeds and appropriations by the State Legislature. In 2017 Medford expects to receive $200,000 in matching funds, or 15% of local revenues.

Q: What can CPA money be used for?

Community Preservation funds can be used for capital projects relating to affordable housing, historic preservation, and open space and outdoor recreation. A minimum of 10% of CPA revenues each year must be spent or reserved for each program area, while the remaining 70% may be used in any program area. Up to 5% of revenues may be spent for CPA administrative costs. CPA funds are not to be used for maintenance or to replace General Fund expenditures.

City departments and nonprofit community partners can apply for funds, which must be used for a public purpose.

Q: Who decides how the money gets used?

Implementation of the CPA is administered by the city’s Community Preservation Committee, which is composed of representatives from the City’s Conservation Commission, Historical Commission, Planning Board, Park & Recreation Commission and the Housing Authority, along with four Medford residents appointed by the Mayor and City Council.

The Medford Community Preservation Committee, with input from the public and other City committees, evaluates community needs and priorities, and makes recommendations for funding eligible projects. As part of its responsibilities, the CPC must develop a Community Preservation Plan, outlining Medford’s needs, opportunities, resources and priorities with regard to open space, outdoor recreation, historic preservation, and community housing. The plan will be reviewed and updated annually, and will include application guidance and criteria for selecting projects.

All CPA funding appropriations must be approved by the City Council. Both CPC recommendation and City Council approval are required for CPA funds to be used.


Q: Does that mean the City must spend 30% of the funds each year?

The City can bank these expenditures for later years. For example, if a significant historic preservation project were envisioned, a portion of the Historic Preservation allocation could be accumulated for that purpose.

Similarly, a large project could be funded over a period of years, with each year’s set-aside satisfying the minimum requirement. Some communities have bonded against future CPA revenues to facilitate major eligible projects. In effect, the requirement for 10% to be allocated to each purpose area is over the long run.

Q: How does the surcharge work?

The city assesses a surcharge of 1.5% on the real estate tax bill, after the following exemptions:

  • The first $100,000 of assessed property value is exempted for all property owners—residential as well as commercial and industrial. So a property assessed at $400,000 would be surcharged as if it were assessed at $300,000; a $700,000 property as $600,000, etc.
  • Low-income homeowners and low and medium-income senior homeowners qualify to request a full exemption from the surcharge.
  • The surcharge means that for every $1 of your tax bill (after exemptions are taken into account) an additional 1.5 cents will be collected for CPA.

Medford's CPA includes every exemption allowed under the law.

Q: Do I qualify for an exemption?

Everyone qualifies for the exemption of the first $100,000 of assessed value. Low-income homeowners and low- to moderate-income senior homeowners can apply for an exemption here. The income limits for full exemption are currently as follows (2017):


Household size Senior (60+) maximum income Low-income maximum income
1 $75,460 $60,368
2 $86,240 $68,992
4 $107,800 $86,240


Qualification for income-based exemptions are based only on income; assets are not taken into consideration. These income levels are derived from annual median incomes and are subject to change over time.  See the 2018 CPA Affordable Housing Income Limits for more information.

In general if you are exempt from property taxes, you are exempt from the surcharge.

Q: By how much does CPA increase my property taxes?

For the average single family Medford homeowner, a 1.5% surcharge on the tax bill means about $53 a year:



Assessed Value Approximate Annual Surcharge
$300,000 $35
$400,000 $53
$500,000 $70


You can estimate your own surcharge: take the assessed value of your home and subtract the $100,000 exemption; multiply by the current tax rate of $11.70 per thousand; and then by 1.5%

Q: How much money does this raise?

About $1.2 million a year in local revenues, plus state matching funds.

Q: How much will the state match?

The state Trust Fund is funded by charges imposed at the Registry of Deeds on every recorded real estate transaction. The state's trust fund is divided among participating CPA communities based on the amount of revenue they raised locally. In 2017 the state match was 17.2%, yielding $214,169 for Medford.

Q: How likely is the state to continue funding the match?

There is no guarantee of the amount of the state match, which is dependent on both the amounts collected in fees, and on the number of communities participating. However, in recent years the Legislature has shown continued support for CPA by augmenting the Trust Fund with additional revenue, reflecting the success of the program and the number of constituent cities and towns participating.

Even without state matching grants, CPA will help Medford to access other state, federal, and private funds to make improvements. Seed money provided by CPA can leverage funds from other sources by providing a local match or by filling gaps in financing that can enable important projects to get off the ground.

Q: What if Medford commits to a large CPA project and the funding is not there to complete it?

Medford's Community Preservation Committee (CPC) receives applications annually for a range of projects of varying size, purpose, and structure. Through its Community Preservation Plan, the CPC establishes criteria and priorities to guide the allocation of funds through a public vetting process. In most cases, CPA projects are selected each year using only currently available funds. There are many important projects that CPA can facilitate with relatively small amounts of funding, which often leverage funds from other public or private sources that enable projects to be completed. In exceptional cases, should Medford wish to use CPA funds to support larger projects that will require multiple years of funding, the local revenues alone will provide a predictable stream of funding. Fluctuations in State funding will not jeopardize Medford's ability to plan for its CPA budgeting.

Q: Can we change our CPA adoption?

Yes. Once adopted, a Community Preservation Act proposal must be in force for five years. After that time, the surcharge percentage and exemptions can be amended through the same ballot-question process. The Act can also be revoked, although no community in the state has ever opted to do so. In fact, several have voted to increase their CPA contribution after a few years of experience with its benefits.
