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.

ADU Rental ROI Calculator Disclaimer
ROI Calculator Notes
- All results shown are an average, based on the numbers entered into the calculator, which include: one or two bedroom ADU, location of ADU and loan length.
- ROI reflects, based on the information entered into the ROI calculator, what an individual could generate on their investment when building an ADU on their property and renting it out.
- Other assumptions taken into account in the calculations:
- The cost of an Accessory Dwelling Unit (ADU) is based on whether it is a one-bedroom ($200,000) or two-bedroom ($250,000). These prices are general estimates provided by Little Home Builder.
- Monthly income (rent) has been calculated by taking the average listing price of five rentals within the selected city during February 2024, as listed on rent.com.
- Monthly cost was determined by adding the cost of the ADU ($200,000 for a one-bedroom or $250,000 for a two-bedroom) to the cost of interest for a loan of that duration, then dividing by the total length of financing.
- The cost of interest for a loan was calculated by multiplying the ADU cost by the interest rate. The interest rate used was 9.09% for a 15-year or 20-year HELOC loan, as reported in Bankrate’s article, ‘Best home equity line of credit (HELOC) rates for February 2024’
- Gross monthly profit was computed by subtracting the monthly cost from the monthly rental income.
- Gross annual profit was calculated by multiplying the gross monthly profit by 12.
- Although we’ve tried to be as rigorous as possible to ensure the accuracy of this calculator, the calculations are estimates and do not constitute a formal offer or promise any certain results. If you need a personalized quote, please contact us at christy@littlehomebuilder.com.
