1. Budget Overruns

Challenge: Many homeowners underestimate how much an ADU will actually cost. Unexpected expenses, like needing to fix poor soil conditions or dealing with price increases for materials, can lead to budget overruns.

• Solution: To avoid this problem, it’s important to get detailed cost estimates before you start the project. This means asking your contractor for a breakdown of all potential expenses, including a contingency fund. A contingency fund is usually around 10-20% of your total budget and is set aside for any surprises that come up during construction.

Pro Tip: Keep track of all your spending during the project to make sure you stay within your budget.

2. Zoning Restrictions

Challenge: Some neighborhoods have specific rules about ADUs. These rules might limit how big the unit can be, how tall it can be, or where it can be placed on your property. This can make it hard to design your ADU the way you want.

• Solution: To navigate these zoning restrictions, work with a contractor who knows your city’s ADU requirements. They will understand the local laws and help you design a unit that meets those rules while still fitting your needs.

Pro Tip: Before you start designing, check with your local city planning office to understand the zoning laws in your area.

3. Utility Hookups

Challenge: Connecting your ADU to essential services like water, sewer, and electricity can sometimes cost more than you expect. If the connections are complicated or need major upgrades, it can add to your budget and timeline.

• Solution: Discuss utility connection options with your contractor early in the planning stage. This will help you understand what needs to be done and get accurate estimates for the costs involved.

Pro Tip: If you have any existing utility issues, address them before starting your ADU project to avoid unexpected problems.

4. Maximizing Small SpacesChallenge: Since ADUs are often smaller than regular homes, it can be challenging to make the most of the available space. You want to ensure that it feels comfortable and functional, even in a limited area.

• Solution: Use smart design strategies to maximize your space. Consider open floor plans that eliminate unnecessary walls, which can make the space feel larger. You can also incorporate lofted ceilings to create a more spacious atmosphere and use multi-functional furniture (like a sofa bed or storage ottoman) that can serve more than one purpose.

Pro Tip: When designing the layout, think about how each space will be used and aim for flexibility in your design.

5. Finding Skilled Contractors

Challenge: Not every contractor has experience building ADUs, and hiring someone who isn’t qualified can lead to delays and poor-quality work. This can be a big headache and might cost you more in the long run.

• Solution: Look for licensed contractors who specialize in building ADUs and have a good track record. Check their portfolios (examples of their past work) and read reviews from previous clients to ensure they have the right experience for your project.

Pro Tip: Ask potential contractors specific questions about their experience with ADUs, including any challenges they’ve faced and how they overcame them.
