3 Top Mistakes Customers Make While Building an ADU


3 Top Mistakes Customers Make While Building an ADU Building an Accessory Dwelling Unit (ADU) can be an exciting and rewarding project for homeowners. ADUs offer the opportunity to increase living space, accommodate multigenerational living, or generate rental income. However, the process of building an ADU can be complex, requiring careful planning and decision-making. In this article, we will discuss three common mistakes customers make while building an ADU and provide insights on how to avoid them.



1. Choosing the Cheapest Contractor and Trusting Them Fully:



One of the most significant mistakes customers make is selecting the contractor solely based on the lowest bid. While cost is an important factor, it should not be the sole determinant in choosing a contractor. Opting for the cheapest option may lead to subpar workmanship, delays, and potential budget overruns. Instead, customers should prioritize quality and experience when selecting a contractor. Conduct thorough research, request references, and review the contractor's portfolio to assess the quality of their previous work. It is also crucial to verify that the contractor is licensed, insured, and has a good reputation in the industry. Requesting detailed project proposals and comparing them based on scope, timeline, and materials can help customers make an informed decision.

Furthermore, trust is essential in any contractor-client relationship, but blind trust can be risky. Maintain open communication with the contractor, ask questions, and seek clarifications throughout the construction process. Regular site visits and progress meetings will allow customers to stay involved and ensure the project is progressing according to their expectations. Retain 10% of all his bills till he finish the rest of the project. Don't be afraid to fire them and replace them! it's never too late for that.



2. Listening to the Contractor More Than the Architect/Designer:


While contractors play a crucial role in executing the construction of an ADU, it is important for customers to remember that the architect/designer is responsible for the overall vision and design of the project. One common mistake customers make is overly relying on the contractor's input and neglecting the expertise of the architect/designer. A contractor may know 2 ways to do something but an architect/designer may know a third way to do the same thing cheaper and quicker. Simply if it's up to the contractor, he wants to do what is easy, fast and would bring more money to his pocket. for example, we had a client insisting on moving an existing column from the pantry based on her contractor's opinion. In this situation, removing the column will mean replacing it by 2 columns and that would be an added cost of around $10,000 going straight into the contractors pocket without a true benefit aesthetically or functionally.

Architects and designers are trained professionals who possess a deep understanding of space planning, aesthetics, and building codes. They work closely with customers to translate their needs and preferences into a functional and visually appealing design. Customers should actively engage with the architect/designer, provide input, and ask questions to ensure that the final design aligns with their vision and requirements.

It is equally important to foster collaboration and communication between the architect/designer and the contractor. Encourage regular meetings and discussions among all parties involved to address any design or construction-related concerns. This collaborative approach will help ensure that the ADU is built according to the intended design, while also considering the practical aspects of construction. Remember that although the architect/designer is not on site, he/she has studied every inch of your project and imagined all the scenarios' that would be happen in this space.



3. Panicking When Delays Occur, Even When the Team Is Working Hard:


Construction projects, including building an ADU, are subject to unforeseen circumstances and delays. Weather conditions, permit approvals, and unforeseen site conditions can all contribute to project timelines shifting. However, one common mistake customers make is panicking and losing confidence in the project when delays occur, even when the construction team is working diligently to overcome obstacles. It is essential for customers to maintain open lines of communication with the contractor and have realistic expectations regarding project timelines. Establishing a buffer in the schedule can help account for potential delays and minimize anxiety. Regular updates from the contractor and transparent communication about any challenges or changes will help customers stay informed and engaged in the process. Customers should trust in the expertise and professionalism of the construction team. If delays do occur, work closely with the contractor to understand the reasons behind them and collaboratively develop solutions to keep the project on track. Remember that open and constructive communication is key to resolving issues and ensuring a successful outcome.


In conclusion, building an ADU is an exciting opportunity for homeowners, but it can also be fraught with challenges. By avoiding these three common mistakes—choosing the cheapest contractor and trusting them fully, listening to the contractor more than the architect/designer, and panicking when delays occur—customers can navigate the ADU construction process more effectively. Prioritizing quality over cost, actively engaging with both the contractor and architect/designer, and maintaining open communication will contribute to a smoother and more successful ADU project. With careful planning and collaboration, customers can bring their ADU vision to life and create a valuable addition to their property.
