Affordable manufactured and modular housing strategies from Norwood, CO; Minneapolis, MN; and Halifax, MA

Overview

Across the country, cities, towns, and counties are seeking new ways to address shortages in housing supply and rising housing costs. To address their housing needs, some localities are encouraging the use of manufactured and modular housing — two methods of off-site construction that allow homes to be built faster and often at a more affordable price point.

Manufactured housing is a term for homes that meet the U.S. Department of Housing and Urban Development (HUD) safety codes and were built in a factory after June 15, 1976; they are constructed on a chassis before being transported to their permanent placement.

Modular housing is one of several off-site construction techniques that allow for the construction of homes in pieces that are then assembled on-site. Volumetric modular construction consists of 3-D printed “modules” that can be combined with other modules to make buildings of varying sizes. Other off-site approaches include panelized construction and the construction of self-contained rooms, such as bathrooms and kitchens. Unlike manufactured housing, which is governed by a national building code set by HUD, modular housing is subject to the same state and local building codes that apply to site-built housing. 

Manufactured and modular housing have some important features that can contribute to efforts by localities and their partners to achieve their housing goals. Manufactured housing is generally significantly less expensive than site-built housing, partly because of the substantial economies of scale that can be achieved when producing housing in a factory, and partly because manufactured housing units tend to be smaller than site-built ones. Modular construction can also be used to achieve economies of scale, but the production cost savings do not always translate into savings for the consumer, given transportation costs and the lack of leverage that individuals or developers have when purchasing only a small number of units.

Compared to on-site stick-built construction, manufactured and modular homes can be produced faster in a climate-controlled environment protected from unpredictable weather. They also often generate less waste, neighborhood traffic, and noise than traditional site-built homes, and on-site construction activity can move inside the structure more quickly — reducing the negative impacts of noise on the projects’ surrounding neighborhoods.

However, there are often barriers to manufactured housing that need to be overcome, like zoning policies that make it difficult or impossible to site manufactured homes in particular localities. Also, manufactured housing owners residing on leased land in manufactured housing communities (or parks) are vulnerable to rent increases that can jeopardize their housing stability. Special efforts may be needed to translate the economies of scale of modular housing into cost savings for consumers.

This three-part series of case studies explores local policy options to use off-site construction in innovative ways. These include using modular construction of single-family housing to make homeownership more attainable to working families, utilizing modular construction of small multifamily housing to reduce the disturbance of neighbors in single-family neighborhoods, and helping manufactured housing owners living on leased land purchase their park and create a resident-owned manufactured housing community.  The case studies cover:

Rural Homes’ Pinion Park in Norwood, CO: Like many other parts of the U.S., some small mountain towns in Colorado, especially tourist areas, are experiencing an affordable housing crisis. Through the Rural Homes Initiative, the Telluride Foundation and its partners are utilizing modular housing paired with low-cost capital and donated land to make affordable housing feasible in multiple localities. This case study focuses on one of the Rural Homes Initiative’s projects, Pinon Park, which provides 24 deed-restricted, affordable, single-family homes for the local workforce. It also shares how coalition-building, multi-sector partnerships, and modular housing can help increase the housing supply and outlines strategies local and state governments can use to encourage similar projects across the country.

Minneapolis Public Housing Authority Family Housing Expansion: While modular housing is most often used for single-family housing, some developers are using it to build multifamily housing and other multi-unit structures. This case study focuses on how the Minneapolis Public Housing Authority is utilizing modular construction to develop 16 buildings that each provide four to six units of deeply affordable housing in residential neighborhoods in Minneapolis and shares ways public housing authorities and localities can work together to pursue shared housing goals.

Halifax Estates Resident-owned Community Conversion in Halifax, MA: Manufactured housing residents who own homes on leased land are more susceptible to housing instability than traditional homeowners; they can be impacted by land rent increases and possibly displaced when a landowner intends to sell. This case study addresses how resident-owned manufactured housing communities can help address these disparities and shares lessons learned from Halifax Estate, a community of 430 units for older adults that became the largest-ever resident-owned manufactured housing community in the country. It also provides ideas for how localities can encourage resident-owned manufactured housing communities and how state policy and third-party technical assistance can help support them.

Telluride Foundation’s Rural Homes Initiative in Norwood, CO


Overview

Colorado rural and mountain towns — especially those with tourism-based economies — struggle to supply enough affordable housing for public service and other workers, which impacts local businesses and the community. Many of these same towns have also seen more remote workers moving there, driving housing prices up and forcing some long-time locals out.

To address these challenges in southwest Colorado, the Telluride Foundation — a nonprofit, community organization operating in Telluride, CO — incubated the Rural Homes: For Sale, For Locals (Rural Homes) initiative in 2015. Launched in three nearby localities (Norwood, Ridgeway, and Ouray), this pilot initiative implemented an innovative approach to building nearly 100 entry-level houses in the region using donated land, low-cost capital, and modular housing construction. Its work was done in collaboration with public and private partners. 

This case study focuses on Pinion Park in Norwood, CO, one of the neighborhoods being created through Rural Homes. It also discusses how multi-sector collaboration and modular construction made it feasible. Pinion Park includes 24 deed-restricted, single-family homes for nearby workers earning ≤120 percent of the area median income (AMI). Lessons learned from Pinion Park may help other localities interested in encouraging modular housing to increase housing diversity and supply.

Minneapolis Public Housing Authority Family Housing Expansion in Minneapolis, MN

 

Overview

 

As of 2021, the Minneapolis Public Housing Authority (MPHA) had a waitlist of over 8,000 families in need of affordable housing. To address this demand for two and three-bedroom units, the MPHA decided to build 84 new scattered-site, deeply affordable housing units in residential neighborhoods across Minneapolis. The Family Housing Expansion Project, as this initiative is called, aims to replace single-family or duplex homes, which is now permissible after the Minneapolis City Council implemented the elimination of single-family zoning announced in the Minneapolis 2040 Comprehensive Plan. This initiative helps to advance the Plan’s goals of increasing the supply of missing middle housing and affordable units.

Through the Family Housing Expansion Project, MPHA is using modular construction to create 16 small multifamily buildings, each consisting of four to six two or three-bedroom units. Sixty-four units will be for households earning at or below 30 percent of Area Median Income (AMI), while 20 units will be for residents with incomes up to 60 percent of AMI to help avoid displacement. The buildings are expected to be completed by late summer 2023.

This case study discusses this initiative in greater detail, sharing how the public housing authority and the city are working together to pursue housing goals and outlining how modular construction is helping increase housing density and the supply of dedicated affordable units in Minneapolis.

Halifax Estates Resident Home Community (ROC) Conversion in Halifax, MA

Overview

In a typical manufactured housing community, residents own their unit but lease the land beneath it from the landowner. Because the land is leased, this tenure provides less security and stability than other forms of homeownership. Residents may experience sudden increases in their rent, if the landowner chooses to raise it, or displacement if the landowner chooses to sell or redevelop the property.

The alternative tenure arrangement of a “resident-owned community” can help promote stability for manufactured homeowners. In a resident ownership model, homeowners form a nonprofit cooperative to purchase the land underneath their homes. This approach gives homeowners direct control over management decisions such as setting rents, establishing community rules, and investing in the maintenance and improvement of the property.

This case study describes the conversion of Halifax Estates, a 400+ unit manufactured housing community in Halifax, Massachusetts. With technical assistance and financing support from ROC USA, a national organization that promotes resident ownership of manufactured housing communities, Halifax Estates successfully became a resident-owned community in 2017. As of late 2022, Halifax Estates is the largest resident-owned manufactured housing community in the country.
