This tool is intended to provide the city with information about proposed zoning changes and existing land use and geographical information throughout the city. 

To use the map, type in and select a specific address you would like to look at, then click on the highlighted parcel on the map. When a parcel is selected, the tool will display certain information about that specific parcel: the year the structure was built; its existing use (what is built there); its existing zoning; and the zoning that is currently being proposed for that area.

“Current” zoning is the pre-overhaul zoning that currently exists for the City. “Proposed” zoning reflects the potential changes that are being discussed, recommended, and voted on in this process.

New zoning proposals have not yet been developed for all areas of the City, so some parcels may not display proposed zoning. 

The sidebar will display the lot’s existing dimensions, the requirements of the current zoning, and the changes to dimensions that would be adopted if the proposed zoning changes are approved. 

Note: What may actually be developed on a specific parcel is affected by more than just its zoning subdistrict designation. Zoning sets the floor and ceiling for what may be developed by-right – but dimensional requirements such as lot size and setback requirements, as well as neighborhood context standards, performance standards, open space requirements, permeable surface requirements, etc., also constrain what is allowable. For example: Just because a 3-story building is allowed by-right in the proposed UR-1 subdistrict does not mean that, if that zoning goes into effect, every lot can or will have a 3-story building developed upon it. Dimensional, context, and performance standards are factors that layer on top of the zoning designation.

The data shown in the map is derived from state GIS sources which are representations of real life data and should not be used as an official reference. Datasets were obtained directly from the city or MassGIS: "Bureau of Geographic Information (MassGIS), Commonwealth of Massachusetts, Executive Office of Technology and Security Services."

The topic will consider tailored, corridor-specific zoning approaches to several existing corridors and main streets in different neighborhoods: 

• High Street between West Medford and the Arlington border

• Harvard Street

• Boston Avenue (not including the Tufts Institutional Zoning district, which will be a separate proposal)

• Main Street

• Broadway

The areas being considered for “corridor” zoning treatments currently exhibit higher residential density; existing ground-floor commercial uses or mix of commercial and residential uses; and/or see high foot traffic and are relatively well served by transit.

Each of these areas is unique, with distinct characteristics and distinct needs. This zoning topic will develop proposals that are responsive to each area’s unique character, while allowing for increased ground-floor commercial uses and increased residential density appropriate for each area.

This zoning topic aims to enhance the existing character and vibrancy of certain corridors in Medford that are especially well-trafficked and travelled; exhibit higher residential density and high housing demand; and have an existing mix of commercial and residential uses that is not supported by current zoning rules. This zoning topic will consider the following goals and strategies: 

• Allow small- to medium-scale mixed-use development by-right along portions of High Street, Main Street, Boston Avenue, and Broadway. 

• Permit a greater range of residential uses, including higher-density residential uses and residential development above commercial development, along portions of High Street, Main Street, Harvard Avenue, Boston Avenue, and Broadway. 

• Bring existing ground-floor commercial uses into conformance with zoning rules, and promote further business growth and active ground floor uses. 

Collaborate with the City of Somerville to align Medford and Somerville zoning rules for the split parcels along Broadway corridor (guided by findings of 2024 Central Broadway Corridor Zoning Study) so as to resolve zoning barriers to development.

Tufts University’s campus has a large footprint within Medford, and the University and its subsidiaries own many properties around campus as well. The University’s properties, land usage, and developments have significant impacts on the surrounding neighborhoods. 

Currently, Medford zoning does not take into account the unique nature of the Tufts institutional area. The City and zoning consultant propose to create a specialized Tufts University Institutional Zone that would tailor Medford’s zoning to reflect and respond to the presence, pressures, and needs of Tufts University. 

This proposal is in its very beginning stages. On May 1st, the Planning, Development and Sustainability Office, zoning consultant, and City Council leadership held a focus group with Tufts University area neighbors and abutters to hear initial questions, comments, and concerns. These comments will help frame the initial proposals for a Tufts Institutional Zone. 

The City of Somerville has Institutional Zoning for Tufts. That zoning, and the strategies it employs, will be considered as Medford takes its first steps in drafting an Institutional Zone for Tufts. 

The goals of an Tufts University Institutional Zone could include: 

• Updating scale, scope, and dimensional requirements to ensure University development integrates well with surrounding residential neighborhoods

• Creating a thoughtful gradient from highest-intensity University development into surrounding residential neighborhoods

• Continuing to encourage development of on-campus student housing, while ensuring this development is scaled and distributed appropriately so as to avoid negative impacts on surrounding residential neighborhoods

• Supporting a thoughtful and appropriate distribution of open space, public realm improvements, and community amenities

As this proposal is in very preliminary stages, the proposed boundaries of a Tufts Institutional Zone are not set in stone. As with all other zoning proposals, residents are encouraged to reach out to Planning, Development, and Sustainability staff and City Council members with their comments, questions and concerns. 

• 5/1/2025 Tufts University Institutional Zone Focus Group Meeting – slide deck

West Medford Square is a beloved neighborhood and locus of small businesses and community centers in the City. However, many residents and business owners agree that it is under-utilized and lament vacant storefronts where many would like to see additional thriving businesses. During the City’s comprehensive planning process, and in initial conversations about an approach to Commercial and Mixed-Use Districts during public Planning & Permitting Committee meetings, many residents expressed a desire to see the new zoning focus on improving development potential in West Medford Square. This is aligned with the citywide zoning strategy to add housing citywide; support more vibrant and mixed-use commercial districts; and build up existing corridors and Squares to better meet Medford’s evolving needs. 

With the West Medford Commuter Rail being one stop away from North Station on the Lowell Line, this Square offers unique access into and out of downtown Boston, and the draft zoning proposal reflects that. This zoning proposal builds upon existing by-right uses to allow greater development potential, both residential and mixed-use, so that this neighborhood can grow to accommodate more residents and support more businesses. In addition, this proposal aims to create a more thoughtful gradient of residential types from the center of the Square out towards the surrounding residential neighborhoods.

These are the height standards that apply to the Mixed-Use subdistricts within the proposed West Medford Square zoning district. 

• Mixed-Use 2A

  • 5 stories by-right

  • 2 additional stories allowed through Incentive Zoning (IZ) 

• Mixed-Use 2B

  • 7 stories by-right

  • 2 additional stories allowed through Incentive Zoning (IZ) 

• Urban Residential 2

  • Townhouses, 3-unit dwellings, multiplexes (4-6 units), and multi-unit dwellings (>6 units) by-right

  • ADUs allowed by-right on lots with 1-, 2-, and 3-unit dwellings

Medford Square is a critical locus for businesses, residents, and important community functions. The goal of the in-progress zoning proposal is to enable Medford Square to grow into a robust, accessible, vibrant downtown while adding housing options in the heart of the City. 

Through Medford’s Comprehensive Planning process, residents expressed an eagerness to see Medford Square blossom into a destination – building on the Square’s existing beloved businesses and attractions to become a hub of gathering places, shopping, and business for residents and visitors alike. In addition, there is a need for more housing options in this central and connected area of the City. Mixed-use zoning will help support the community’s vision for a thriving downtown with commercial activation along Medford Square’s streetscape and multiunit residences on buildings’ upper floors. 

This zoning proposal builds upon existing by-right uses to allow greater development potential, both residential and mixed-use, so that this neighborhood can grow to accommodate more residents and support more businesses. This proposal aims to create a more thoughtful gradient of residential types from the center of the Square out towards the surrounding residential neighborhoods. The draft zoning aims to collaborate with the topography of the Square to in the allocation of different by-right heights, and to consider the sightline to the Mystic River and downtown Boston in crafting the map of Medford Square zoning. Finally, this zoning will also consider creative ways to maintain parking access while prioritizing an active streetscape.

These are the height standards that apply to the Mixed-Use subdistricts within the proposed Medford Square zoning district. 

• Mixed-Use 1

  • 4 stories by-right 

  • 1 additional story allowed through Incentive Zoning (IZ) 

• Mixed-Use 2A

An Accessory Dwelling Unit, or ADU, is a small residential unit that is located on the same lot as another home. ADUs can be located within an existing primary residence, like a basement apartment, or they can be a separate structure on the same lot as an existing primary residence, like a converted detached garage apartment or cottage apartment. 

Section 94-8.2 of Medford’s Code of Ordinances currently allows for ADUs on residential lots in Medford if certain conditions are met. These conditions include things like floor area relative to the principal dwelling; parking; owner occupancy; and building regulations. 

ADUs are a strategy for increasing housing options within the fabric of existing neighborhoods, and give owners the option of adding living spaces to under-utilized spaces on their property. ADUs also help communities diversify our housing stock. They are by definition small-scale living spaces, which is meaningful in communities such as Medford, where demand exceeds supply for living spaces like one-bedroom apartments that are suitable for young adults and elders looking to downsize within their community.

The 2024 Affordable Homes Act requires that ADUs must be allowed by-right in residential districts where single-family homes are allowed by-right. The City Council is in the process of updating the City’s ADU regulations to comply with that new state law and make decisions about other aspects of ADU regulations that are left as local options.

The 2024 Affordable Homes Act created new requirements for ADU regulations in all Massachusetts communities. The new law requires that ADUs (subject to certain size and building regulations) must be allowed by-right in any zoning districts where single-family homes are allowed by-right. The purpose of the law is to lower the barriers to developing ADUs by prohibiting municipalities from imposing certain regulations on ADUs in certain zoning districts. The full text of Chapter 150 is available online, as is the full text of 760 CMR 71.00 which details Protected Use ADUs. 

ADUs in districts where single-family zoning is allowed by-right are referred to as “Protected Use ADUs.” The state law sets forth regulations that may not be imposed on Protected Use ADUs.

• Municipalities cannot impose an owner-occupancy requirement.

• Municipalities cannot impose minimum parking requirements. 

• Municipalities cannot impose use and occupancy restrictions. 

• ADUs cannot count towards density calculations. 

• Both detached and attached ADUs must be allowed by-right. 

• Dimensional standards for Protected Use ADUs cannot be more restrictive than the dimensional standards imposed for the principal dwelling where the ADU is being constructed. 

• Municipalities cannot prohibit Protected Use ADUs for nonconforming lots or principal dwellings on the basis of that nonconformance. 

• These regulations remain the same for Protected Use ADUs in Historic Districts, however, municipalities are allowed to establish Design Standards and Dimensional Standards for Protected Use ADUs in Historic Districts. 

While this law requires municipalities to permit ADUs in certain areas, building and size regulations still apply to Protected Use ADUs. For example, Protected Use ADUs must have a separate entrance that meets safe egress requirements; and they can be no larger than 900 square feet or less than half of the gross floor area of the principal dwelling, whichever is smaller. 

ADUs that aren’t located in districts where single-family zoning is allowed by-right are referred to as “Local ADUs.” Municipalities have choices when it comes to regulations on Local ADUs. Those choices include: 

• Should the City allow ADUs by-right or by special permit in other residential zoning districts (not just where single-family residences are allowed by right)?

The Committee has requested language that allows ADUs by-right in all residential subdistricts, but with the exception of not allowing ADUs on lots with townhouses, multiplexes, or multifamily buildings with more than 6 units. This would prioritize ADUs on residential lots that are lower in density, and not allow ADUs on residential lots that already feature higher-density housing options. 

• Should the City allow ADUs bigger than 900 square feet (or greater than 50% of gross floor area of the principal dwelling)? 

The Committee has so far affirmed the zoning consultant’s recommendation to maintain that ADUs should be either 900 square feet or 50% of the principal dwelling’s gross floor area, whichever is smaller. The intent of ADUs is for them to be dimensionally subordinate to the principal dwelling area. 

• Should the City allow a second ADU on the same lot where one exists already?

The Committee has requested language that requires a second ADU on a lot where one already exists to go through the Special Permit process; and that requires that if the first ADU is detached, the second must be attached, and vice versa. 

• Should the City allow the short-term rental of ADUs? 

The Committee has so far expressed a desire not to allow short-term rental of ADUs. This is in keeping with Medford’s current ADU regulations, and the goal of having ADUs increase Medford’s long-term residential housing options. 

The Planning & Permitting Committee has been discussing these questions with the zoning consultant and City staff since March. For the next Committee meeting on this topic, the zoning consultant will prepare an updated draft amendment to the City’s ADU regulations that reflects the above inclinations and requests. The zoning consultant is also reviewing potential amendments to dimensional standards and requirements. 

As is the case with every zoning proposal, after the draft is reviewed and reported out of the Committee, it will be referred to the Community Development Board for further review and public comment.

Is there a minimum lot area required to develop an ADU? 

There isn’t a minimum lot area required to develop a Protected Use ADU. However, ADUs must meet state and local Building Code. 

I’m in the process of developing an ADU for my property and I need help. Where should I turn? 

For current ADU development questions, please reach out to the Building Commissioner.

The purpose of the Mystic Avenue Corridor District is to allow a mix of uses, including multifamily, commercial, and light industrial to meet the following needs for this corridor, as articulated by the Medford Comprehensive Plan, Housing Production Plan, and Climate Action and Adaptation Plan.

1. Allow a wider variety of uses and building types to support jobs and economic development near established residential neighborhoods, providing options for living within walking distance of jobs, goods, and services.
2. Allow mixed-use, multifamily, and commercial uses at a density appropriate to a walkable, urban corridor.
3. Update design standards to buffer abutting neighborhoods from the higher intensity of uses and reinforce a corridor identity along the length of Mystic Avenue.

What is zoning?

Zoning rules are how communities govern what may or may not be built, and where. Without zoning, a developer could build a single-family next to a highway, or a high-rise next to the Fells. With zoning, we create the rules for what may be built where, and what conditions that developers must adhere to – height, number of units, what the building will be used for, dimensions, amount of open space on the lot. 

Through zoning, we organize our community into districts and develop rules and standards for each, according to what makes sense for that area. Zoning is how we control what the fabric of our community looks like.

Why should we update our zoning?

The City of Medford spent years reaching out to thousands of Medford residents to form the foundation of our new Comprehensive Plan, Housing Production Plan, and Climate Action and Adaptation Plan. These documents articulate our shared community goals of incrementally increasing our housing supply, reducing emissions, promoting vibrant and walkable neighborhoods, and more. Medford’s zoning overhaul, the first major one in decades, addresses outdated and inefficient codes that hindered housing and mixed-use projects. By modernizing these regulations, the city is creating a foundation for equitable development, making it easier to build affordable housing and mixed-use developments, while promoting energy-efficient buildings and walkable communities. These updates will reduce car dependence, support small businesses, and create hubs that benefit the environment and economy, positioning Medford for a greener, more connected, and resilient future.

So we’ve changed zoning. How fast will I notice changes? 

Changing zoning does not mean that changes happen immediately or overnight. Changing zoning means changing what can happen when property owners or developers decide to develop vacant lots or redevelop existing buildings. When we change zoning, we change what a property owner or developer is allowed to do with their property. It does not force changes to the parcels or properties. 

What does it mean that something is done “by right”?

“By right” means what a developer or builder may do as a matter of course, without any need to seek special permissions, building permits, or zoning variances: a type of use (i.e., a medical office, a multiunit residential building), or a characteristic of the building (i.e., number of stories or units, or setback from the sidewalk).

What does it mean for businesses and existing buildings when zoning rules are updated? 

Under all zoning, whether new or unchanged: 

• If an existing use is “nonconforming” with current zoning, it can continue. 
• If the use stops for more than two years, then the use is no longer allowed, regardless of ownership (i.e. if the property changes hands, or doesn’t). In other words: If the business sells to another owner, the same use can continue, as long as there hasn’t been a lapse of 2 or more years since the prior business was open and operating at the site.
• If an owner wants to sell for a different nonconforming use, for example, a New Dealership to a Used Dealership, that would be considered a change of use and would not be allowed.
• Medford allows Use Variances via the Zoning Board of Appeals. However, it’s a high standard to be able to receive a Use Variance; the decision is based on a lot’s shape, topography, and soil conditions. Use Variances are not awarded simply because a new use is similar to a prior approved use.  
• Existing nonconforming uses need to get a special permit to increase the non-conformity.  For example, this would occur if an owner wanted to expand an existing, nonconforming building to do more business under the same use at the same site. 
• Other subtleties may factor into existing non-conforming properties that have different rights. For specific questions and specific cases, property owners should consult with a zoning lawyer on their rights and responsibilities under MGL Ch 40A. 

Before the current zoning overhaul, the City amended its zoning table of uses in 2023. A zoning table of uses shows what type of activities, buildings, and businesses are allowed or not allowed in certain parts in a city. The 2023 Zoning Table of Use amendments  aimed to reflect the current needs of the community, making updates to outdated definitions, and changing the approval process of certain uses.
