ADU Cost Calculator
Are you contemplating the costs of adding an Accessory Dwelling Unit (ADU) to your property? As specialists in ADU construction at Little Home Builder, we understand how daunting this process can seem. That’s why we provide a free ADU cost calculator to help you estimate your potential expenses.
Not only can an ADU increase the value of your property, but it also offers potential for rental income or extra space for family. Start your journey towards building your tiny home by using our calculator.
How is ADU cost determined?
Typically, several factors contribute to the overall cost of an Accessory Dwelling Unit (ADU). These fall into pre-construction expenses such as design and site planning, site preparation including foundation and dirt displacement, as well as materials and labor costs.
It’s generally a good practice to estimate the cost of building an ADU based on the size and value of the main dwelling. For instance, if the ADU is about 30–40% the size of the primary home (which is a common size allowance), it might cost around 30–40% of the home’s value to construct. So, for a home valued at $600,000, the estimated cost to add an ADU would range from $180,000 to $240,000.

Stick Built Quality Construction
Stick-built ADUs are constructed the same way your house was built with craftsmanship and based on today’s building code. It’s clear what you’re getting when you build in the traditional way. Lenders are comfortable with the building method and should have no issue providing financing. Appraisers will have no issue evaluating this structure when it’s time to sell or refinance. Once the plan is permitted, you can be confident it was designed to Colorado’s efficiency standards and to withstand Colorado weather.

- The results presented by this calculator are estimates derived from the inputs you provide, and should not be interpreted as an actual quote. Inputs affecting the estimate include but are not limited to: the square footage of the ADU, number of bedrooms and bathrooms, existence of a structure that needs removing where the ADU will be built, whether the construction area is flat, and whether you already have a floorplan or are working with a builder on a pre-designed one.

Furthermore, the estimate does not account for pre-construction site preparation, permit acquisition, utility connections, city fees, and taxes, which are variable and excluded from the calculation.
