ADUs in Plymouth, MA

Accessory Dwelling Units in Plymouth, Massachusetts

In recent years, many cities across New England have begun to encourage the construction of ADUs as a way to address housing shortages and increase housing affordability without significantly altering the character of established neighborhoods. In the largest Town in Massachusetts, Plymouth, MA, Accessory Dwelling Units (ADUs) are now allowed by RIGHT in all residential and mixed-use zoning districts with few restrictions*

Often referred to as America’s Hometown and the first permanent colony of Massachusetts, Plymouth, MA’s unique history, location, architecture, and current economy leave the typical home cost near $600k, quite a bit higher than the national average.

This also makes housing rental costs higher, nearly $2,700 in 2024 making it nearly 35% higher than the national average and a less favorable destination for qualified workers needed to sustain and grow the workforce.

The new ADU-friendly by-laws, passed unanimously by the planning board in a 5-0 vote, support Massachusetts’s broader focused Healey-Driscoll Administration’s $4 Billion Affordable Homes Act. But they are specifically written to benefit Plymouth residents by increasing the number of dwelling units available for year-round rental in the Town. This supports the local workforce while providing rental income to residents on fixed incomes who would like to remain in their homes.

One notable exclusion is that ADUs cannot be used as STRs (short-term rentals) like Airbnb or VRBO.

New England residents are rapidly adopting ADUs as the perfect solution for a growing family or to house extended family as multi-generational living gains popularity in the USA.

A Brief History of Plymouth, MA

In 1620, a group of English Settlers, later known as Pilgrims, landed at Plymouth Rock on Cape Cod in Massachusetts, which was then established as Plymouth, the first permanent European settlement in New England. They had originally aimed for the Hudson River but instead landed at Cape Cod. When they arrived, they signed a document called the Mayflower Compact that loosely established a rudimentary form of government.

The first few years of Plymouth proved to be very difficult. They faced hardships like disease, harsh weather, and a lot of tension with the local tribes. The pilgrims did, however, make friends with the Wampanoag tribe, which may have been one of the only reasons for their survival. This is who the colonists sat down to dinner with on the first Thanksgiving, which went on for three days!

Plymouth was able to grow, and life became easier for the colonists. Before long, Plymouth was a center for agriculture, fishing, and all kinds of trade. In 1691, Plymouth and Massachusetts Bay Colony came together to form the Province of Massachusetts Bay.

During the Revolutionary War, Plymouth supported their fellow colonies by serving as a base for American soldiers who raided British ships. There were quite a few brawls between the American and the British troops there as well.

As the years went on, Plymouth moved more toward factories and tourist attractions to support its economy. They became known for producing rope, textiles, and much more. Since Plymouth was such a historical site with so much history about the pilgrims, it became a very popular tourist attraction as well.

In fact, it’s still a very popular tourist spot today. You can see things like Plymouth Rock, a replica of the original Mayflower, and a living history museum called the Plimoth Patuxet, that re-creates the original Plymouth Colony. Plymouth is doing quite well for itself these days. In fact, just in 2020, it had a big celebration for its 400th anniversary. They’ve also got great schools, a thriving economy, thanks to all the tourism, and excellent healthcare.

Architectural Influences In Plymouth

There is a lot of history in the architecture of Plymouth, Massachusetts, and the town itself. Since Plymouth is one of the oldest settlements in America, its architecture has been influenced by many different styles over time. For this reason, it has a very eclectic collection of buildings and structures.

One of the most common styles you will see quite often is the Colonial style, which was popular in the 17th and 18th centuries. Some of the oldest buildings in town, such as the courthouse and the 1809 Hedge House were built in this Colonial style. They would often have central chimneys, shingle, or wooden clapboard siding. It was a very forested area, and they were able to use a lot of the timber for building materials.

Plymouth grew and grew during the 19th century. Many new architectural styles were starting to emerge. The Plymouth Town Hall(built in 1840) was modeled after the Greek Revival architecture. Greek Revival was popular in the mid-1800s and had characteristics such as low-pitched roofs and large columns. Another style that greatly influenced Plymouth’s architectural diversity was the Victorian-era style. The Queen Anne was particularly popular among the large homes and mansions, such as the Harlow Old Fort House, built in 1875. It boasts decorative brackets, towers, and beautifully detailed woodwork.

In the early 1900s, another new style was becoming popular, it was called the Colonial Revival style. It was sort of a tribute to the old Plymouth Colony and its history. The Plymouth Public Library, which was built in 1921, was built in this style with all the detailing and the brick walls and wood siding.

Plymouth’s architecture is still evolving with new projects and innovative designs, while often still incorporating a lot of the town’s historic roots. As a result, Plymouth is an interesting blend of the old and the new. It shows off Plymouth’s legacy as a town with a rich history and continued prosperity.

Frequently Asked Questions

Most common asked questions about ADUs

What Are Accessory Dwelling Units (ADUs)?

Accessory Dwelling Units (ADUs) are versatile living spaces that are constructed on the same property as a single-family home or, in some cases, on multi-family residential properties. ADUs are known by various names, including guest houses, mother-in-law units, granny flats, or backyard cottages.

There are two main types of ADUs:

– Detached Units: These are standalone structures typically situated in the backyard or on the side of the property.

– Attached Units: These are created by converting existing space within the primary home, such as an attic, garage, or basement.

How Does an ADU Impact My Home's Value?

The presence of an ADU on your property can have a positive impact on the overall value of your home. This is primarily due to the income potential that ADUs offer. By renting out the ADU, homeowners can generate an additional stream of revenue, which is attractive to potential buyers.

However, it is essential to note that the exact impact on your property’s value may vary and should be assessed by seeking a second, independent opinion. Factors such as the local real estate market and the quality of the ADU can influence the extent to which it affects your property’s value.

Why Are ADUs Becoming More Popular?

The rising popularity of Accessory Dwelling Units (ADUs) in the United States can be attributed to several compelling factors. Firstly, ADUs serve as a practical response to the ongoing housing crisis, providing a viable solution to the shortage of housing options. Additionally, ADUs offer homeowners the opportunity to generate supplementary income, making them financially appealing.

Furthermore, ADUs are recognized for their cost-effectiveness and environmentally friendly nature. They maximize the efficient use of available land resources, making them a sustainable housing option. Moreover, ADUs align with evolving socioeconomic trends in the U.S., facilitating aging in place and the creation of multigenerational households. These benefits translate into easier and more cost-effective care for aging parents.

Moreover, homeowners are increasingly turning to ADUs as a means of diversifying their income sources. The trend toward downsizing and minimalist living is on the rise, and ADUs enable individuals to simplify their lives while still enjoying the comforts of a neighborhood setting.
