At Knuk, our models are clearly priced so you can get an idea for what each base model build costs. Adding accessories, decks, pergolas and more will increase the cost of a base model Knuk. You control the cost of your Knuk by determining your budget and which design best meets your needs.

What does an accessory dwelling unit cost?

This is a simple question with a complex answer. When you build an ADU it is important to know what the purpose of your dwelling unit will be. Once you’ve decided what you will use it for, then we can explore the costs associated with building your new space.

As a property owner, the second thing to consider is the size of your property, local zoning and use requirements, property lines, setbacks and more. A quick trip to your town hall or city’s website might answer your preliminary questions about building a detached building on your property.

After assessing your property for usable land combined with the purpose of your new space, we can get busy deciding on square footage and building size. Considering that residential and commercial uses often vary considerably, we encourage you to contact us here at Knuk and have an introductory conversation about your project. This can help set you on the right course in making some important decisions. Oftentimes we can give you a rough estimate of cost per square foot, which can help inform your building budget and design ideas.
After all the initial decisions are made, you can get down to business determining the costs associated with your Knuk music studio, pool cabana, office, or art studio.

Do I need to pay someone to design my ADU?

Depending on your preference, Kunk has pre-planned designs that you can choose from for your small building. We offer a standard building size with a few variants for layout, from squares, rectangles, or L-shaped buildings. You can up-size in standard building size increments as well.

In these pre-designed layouts, your design responsibilities are focused on finishing options like color, materials and add-on designs. We provide these design services as part of our one-source building process. Combine any roof, siding, window, door, or floor plan and make your Knuk, well, yours.

If you are keen to design your very own little outbuilding, then our professional Knuk architects and designers will design it for you. Custom options are available for any ADU, allowing you to design your very own one-of-a-kind building that fits your property and purposes perfectly.

What other costs are associated with building a residential or commercial ADU?

There are other costs to consider when building an ADU on your property. Local permits, inspections, and other location-specific requirements may have costs associated with them. Contact your town or city’s building department to find out what you need to be aware of when planning your build.

Every ADU will need some type of foundation. Some are placed directly on a gravel pad, others are elevated on pilings or stilts for water mitigation. Still others may be placed directly on a concrete foundation that is poured and cured in advance. Having the foundation prepped and ready for your Knuk delivery is an important part of the build process. We will review your foundation plans with you ahead of time to make sure that build day goes smoothly.

Your Knuk is delivered in strategically pre-built sections that are then assembled onsite. Regardless of which Knuk you purchase, your site will need to be accessible to heavy machinery for the delivery and placement. If you are building in a more remote or secluded spot, there may be additional expenses associated with site accessibility. Special vehicles can be used to haul materials out to a remote build site. A special site delivery may carry a higher price tag than an easy to reach foundation.

One of the most variable areas of cost is the interior and finish designs that you choose for your ADU. If you are on a budget, you can choose less expensive trims and details, keeping with a minimal design and relative costs. With a bigger budget, the choices increase and allow you to customize your new space more elaborately. Flooring, windows, hardware, roofing material, siding material, accessories like decks, patios, porches, arbors, or pergolas for example all come in varying costs and complexity.

Does it actually add value to my property in the long term?

Local permits and building codes can impact your options, but in almost every neighborhood ADUs are an acceptable addition to your property. From a 250 square foot studio to a 650 square foot tiny two-bedroom, optimizing the space is critical for maximizing your value.

From recreation spaces to expansive campus living, adding an ADU can increase your property value from 25-50% depending on location, quality and flexibility of use. Generally speaking, a well-built building holds its value much longer than an inexpensive shed model. Therefore, when you add a Knuk to your site you are adding value in a high-quality, luxury-level building and living experience.

By adding an exquisite pool cabana to your outdoor recreation area, for example, you’re adding value and functionality that becomes a unique selling point for future consideration. The more versatile your space, the more value you are adding to your property.

Additionally, your Knuk is built to weather storms, and sunshine alike. From coast to coast, mountain top to valley, city to farm and anywhere in between, your Knuk is built to last for generations to come. We think that adds value to both your lifestyle and your property.

Can I get a loan and finance my new accessory dwelling unit?

Like any new building project, financing is always available to qualified buyers. Your concierge team at Knuk will help identify financing options for your building project if necessary. Contact us first to determine your goals, location and design ideas. Then we can venture into financing options.

When you begin the Knuk journey, we make sure that all your needs are met when it comes to your ADU financing options, clarifying any additional costs up-front, determining installation costs before placing your order, determining your Knuk’s square footage, design, materials, finishes and the building timeline. Our goal is to deliver your new ADU with gold-key quality on the closing date agreed on at the beginning.

We hope we’ve answered some of your questions and clarified the costs associated with building your new ADU near you.
