Modular vs. Traditional ADUs: What You Need to Know

Introduction

An accessory dwelling unit (ADU) is a smaller living space built next to a primary living space. An example of this can be an in-law suite next to a main house. 

In Colorado, ADUs have become a popular method of creating living spaces in homes. This is attributed to the shortage of homes, loose zoning laws in areas like Denver, as well as competitive prices in areas like Fort Collins.

If you want an efficient and affordable method of creating more living space, modular/traditional units are the way to go. Be it a home office or a granny flat, the possibilities are endless. 

What is an ADU and How Does It Work?

As mentioned above, an ADU is a secondary dwelling flat built on a main property. They have variations such as a granny flat, casita, in-law suite, flex flat, and a tiny home. 

Built on the same property as your main residence, a modular flat is a smaller unit that can have various uses depending on your needs. 

ADUs exist in a plethora of forms, with most having their own kitchen, bathrooms, and entrances. These facilities are ideal for families and can be attractive from a rental perspective.

In Colorado, there are two main types of ADUs allowed, detached and attached: 

  • Attached

As the name suggests, attached ADUs are constructed in a way that at least one wall must be attached to the main house. This structure is ideal for a home office or a gym.

  • Detached

A detached ADU has no walls attached to the main house and is its own separate living space. This structure is ideal for a guest house or cross-generational living as a result of its added privacy. 

The Difference Between a Modular and Traditional ADU

Are you a Colorado homeowner interested in building an ADU but aren’t sure how to choose between modular and traditional? Let’s break it down to help you decide. 

Modular ADUs, which are factory-produced, offer lower costs due to faster building times and standardized processes, leading to high-quality, affordable ADUs. 

Traditional ADUs are built on-site, meaning customers have full flexibility in customization. They might take longer to build, but are tailored to the customer’s preference. 

Depending on what your priority is, taking these differences into account can help factor in making the correct choice. 

Modular ADU: The Pros

Colorado’s accessory dwelling units are gaining popularity due to affordable prices and high quality. Let’s break down why a modular unit is the right choice. 

  • Faster Construction Time

Modular ADUs produced in a factory use standardized methods, reducing construction time and delays caused by weather or traffic. On-site foundations being built simultaneously make installation quicker.

  • Lower cost

Since modular ADUs are produced in factories, labour costs are reduced. Due to standardized production, modular homes are built in a short amount of time, reducing the labour hours, thus reducing the overall cost. 

  • Quality Assurance

Modular ADUs are built in controlled factory environments where production occurs in a streamlined process, ensuring that every build features a high-quality, durable design.

  • Sustainable Developments

Modular units feature sustainable and energy-efficient ADUs. With a focus on being eco-friendly, these units are ideal as factory-built builds ensure materials are not wasted. This ensure that less energy is used in production.

Traditional ADU: The Pros

Areas such as Fort Collins have competitive housing prices. Adding an extra unit allows for rental space in such places. But why choose to build a traditional ADU?

  • Custom ADU

As the ADU is built onsite, the homeowners and builders will have full control over the design. Whether you choose a granny flat or a mother-in-law suite, customizations are up to you, so you truly receive what you ask for. 

  • Property Value

Traditional ADUs, such as In-Law Cottages, are recognized as more permanent as they feature a traditional method of construction. This is ideal as it can lead to higher resale value, an exciting advantage for homeowners.

  • Integrated Appearance

Since traditional ADUs are built onsite, they can be customized entirely by using the same materials and styles. If the traditional unit matches the layout of the main house, then a higher resale value can be attributed. 

  • Adaptability

With traditional ADUs featuring a conventional construction method, it is easier to build in homes with irregular spaces that have uneven terrain, as the construction method can be adapted to fit the space around the home.
