An additional dwelling unit is a secondary housing unit that is separate from your main home. Additional dwelling units (ADUs) offer a number of benefits. They offer an additional living space for family, rental income, office, and can even increase the value of your property if you plan to sell in the future. Whether you need extra space for an aging family member or want to increase your passive income, an ADU can serve a multitude of purposes. Many homeowners want to move forward with their ADU plans. However, they often wonder, how long does ADU construction take? Below, you will find helpful information about ADUs and their average timeline.

How Long Does ADU Construction Take?

An ADU project involves a number of phases. Because of this, every project timeline is different. On average, most ADUs take roughly 12 to 18 months to finish. However, there are opportunities for it to move faster. In addition, there are setbacks that could make it last long. This is why it is critical to work with a design and build firm. They can ensure that your project is completed how you want and on time. There are four steps to each ADU project that can make or break your project timeline. Consider the following and be sure to plan in advance to stay on track.

Financing:

Funding can take between 60 to 90 days. However, this depends on current interest rates and the demand for loans at the time. It is recommended that you secure roughly 10 to 20% over your total construction estimate. This is necessary to cover unforeseen expenses, which is common in many construction projects. Your budget should account for the design, permits, construction, contingency, and any ancillary items you would like. Plan your budget in advance and secure funding as soon as possible so you can get started on your designs.

Design:

The design portion of the ADU project timeline can take between 6 weeks to 3 months. Planning generally involves site measurements, schematic design meetings, design development meetings, and construction meetings. This phase of the process requires realistic goals. In addition, those goals should align with your budget. If you plan on reselling in the future, consider potential additions that can add further value when you sell. Working with a reputable design firm can ensure this phase of the process is smooth and swift.

Permits:

Each jurisdiction is different, but permits can take roughly 60 days. This can take longer, so it’s important to submit your application as soon as your design plans are completed. Be sure to check with your locality’s guidelines on permits for an additional dwelling unit. This is another reason why it’s beneficial to work with a design firm, as many submit and oversee this process for you. Permits are integral to the entire process, so it’s necessary to comply fully with the requirements.

Construction:

The construction phase is the most exciting part of the entire process. The actual build can take between 5 to 8 months. However, this step depends on a number of different factors. The size of the build, the detail included in the build, the weather, potential supply chain issues, labor shortages, and how busy the design firm is can impact the timeline. Work with your designers and builders before the process begins to ensure everyone is on the same page.
