Investing in prefab homes in Wisconsin is a great way to expand your living space without the need for home remodeling and construction work. Plus, it's more affordable, and you can use the tiny house for work or leisure purposes. 

However, there are specific laws that you need to be wary of before you can start building accessory dwelling units (ADUs) in your backyard. This comprehensive guide will cover the different regulations pertaining to manufactured homes in Wisconsin that you must consider. 

Keep reading until the end, as we will explore the costs of a tiny home in Wisconsin and how you can save money by investing in an Autonomous ADU. Let's get started! 

The Wisconsin Prefab House and ADUs Regulations to Consider

When it comes to building and installing prefab homes in Wisconsin, homeowners need to consider the different rules and regulations, which may vary at the state and local levels. 

The following are some of the general guidelines that you must consider before building and installing prefab ADUs in Wisconsin: 

Property Designations

You cannot install a prebuilt ADU anywhere you like. The state has rules and regulations for manufactured homes in Wisconsin, including property designations. 

In Wisconsin, the government gives specific designations to different areas, and these include the following: 

  • Residential
  • Commercial
  • Mixed 

The above-mentioned designations determine whether you can build modular homes in a particular area. Each region will have a different designation, which you must follow. 

If the state gives a commercial designation to an area, for example, it may not be possible for you to build a prefab ADU for the purpose of residential living.

Property Designations

Size and Height Restrictions

There are also size and height restrictions that you must adhere to if you wish to install a prefab house in Wisconsin. These regulations may vary according to the zoning district, and you may find more information about them in the local zoning codes. 

The design of the prefab homes or ADUs must adhere to the state's building codes and architectural standards. Typically, the maximum size and height depend on the lot's size or the primary dwelling's square footage. 

Depending on the county, the minimum size of a tiny house in Wisconsin is between 120 and 200 square feet (with at least one habitable room). 

Setback Requirements

Another important regulation that you must adhere to is the setback requirements. These refer to the minimum distance that prefab homes in Wisconsin must be located from public streets, roads, rivers, and other structures. 

The goal of implementing setback requirements when it comes to modular homes in Wisconsin is to ensure safety, privacy, and proper spacing between the buildings in the state.

Setback Requirements

Development Standards

Residents living in Wisconsin not only have to adhere to the development standards of the state but also the local governments (depending on the municipality)

Development standards are a broad set of requirements pertaining to prefab ADUs in Wisconsin, and they cover the type of materials used, architectural design, and landscaping, among others. 

If you're looking to install a prefab studio in Wisconsin, it's crucial that you thoroughly go through the local building codes or consult with an expert on the different development standards. 

Height Limitations

The height limitations may vary depending on the zoning districts in Wisconsin. 

If a particular municipality requires a maximum height of 24 inches from the ground to the diagonal strap attachment, for example, you cannot exceed that limit. 

Fire and Security Safety Requirements

When building and installing prefab homes in Wisconsin, it's important to consider fire and security requirements. 

If your outside shed or tiny home studio doesn't meet the specific requirements mentioned in the building codes, you may not have permission to place it on your property. 

Fire and security safety requirements specify the type of materials and smoke detectors used in the prefab studios. It may also include the need for fire exits and other safety features to keep the occupants safe.

Fire and Security Safety Requirements

Accessory Structures

Depending on the zoning region, some local ordinances may treat prefab homes as accessory structures. 

When building and installing manufactured homes in Wisconsin, it's crucial to adhere to the rules pertaining to detached garages and sheds if the local ordinance treats the ADU as an accessory structure. 

Historic Districts

It may come as a surprise to know that there are around 2,300 properties and districts mentioned on the National Register of Historic Places in Wisconsin. 

These areas may have additional regulations and design requirements that property owners must follow when building and installing prefab homes in Wisconsin. This helps ensure the historical significance of the region. 

Utilities and Infrastructure

Prefab ADUs in Wisconsin must also adhere to the utility and infrastructure requirements, which may include connections to the water, sewage, and electricity supply. 

It's essential that you check with the local utility providers to determine the different utilities and infrastructure requirements before building and installing an affordable backyard ADU

Electrical and plumbing systems may require proper installation and fixtures while adhering to safety, health, and sanitation standards.

Utilities and Infrastructure

Permit Process

Before property owners can start building modular homes in Wisconsin, they must get the necessary permits. 

To get a permit for building a prefab house in Wisconsin, you must submit a detailed construction plan and documentation to the local permitting authority. 

The relevant department will inspect the property and review the plans for compliance with the local building codes, fire and safety requirements, and other regulations. 

Legal Rental Requirements

Investing in prefab homes in Wisconsin is a great way to generate a source of income, as you can rent out the space to others. 

However, before you can even let anyone stay at your property, you must familiarize yourself with the legal requirements for rental units in the state to avoid trouble with the law. 

The building codes and legal requirements for prefab ADUs in Wisconsin may vary from one county to the other. It's crucial to hire a professional constructor or architect to help guide you on the rules and regulations before installing a tiny home.

Sustainable Design Practices for ADUs in Wisconsin

If you're considering building a high-performance home in Wisconsin, you must take the necessary steps to ensure sustainability and energy efficiency in every aspect of your living space. 

To reduce electricity consumption, you must invest in proper insulation and energy-efficient windows that maintain and regulate the indoor temperature. This minimizes energy waste and helps you save on utility bills. You can even take it a step further by investing in a solar system to stay off the grid. 

By considering passive design strategies, you can maximize the natural lighting and ventilation in your ADU or prefab home. This will help you save on cooling or heating costs all year round. 

Rainwater harvesting systems can remove your reliance on the local water supply, while sustainable building materials can help you create a greener ADU in Wisconsin.
