Most of the expensive problems in a home project aren’t made on the job site. They’re made months earlier, in the planning — or the lack of it. After 40 years in the building trade, these are the seven mistakes we see families make most often.
1. Assuming an ADU Is the Only Answer
An ADU can transform a property, but it isn’t always the right fit. Sometimes a remodel or an addition gives your family the space it needs for less money and less disruption. Start with the problem you’re trying to solve, not the product.
2. Skipping a Property Evaluation
Setbacks, utilities, slope, and access all affect what you can build and what it will cost. A proper evaluation of your lot up front prevents redesigns and surprises later.
3. Underestimating the Full Budget
Construction is only part of the cost. Permits, plans, utility connections, site work, and finishes add up. Plan for the whole project, and keep a contingency for the unexpected.
4. Choosing on Price Alone
The lowest bid often leaves things out. Compare what each bid actually includes, ask how changes are handled, and choose the team you trust to communicate honestly when something comes up.
5. Not Planning for How You’ll Live
Will a parent need single-level living? Will an adult child eventually move out? Design for how your family will use the space in five or ten years, not just today.
6. Ignoring Local Requirements
Every city has its own rules for ADUs, additions, and major remodels. Understanding them early keeps your timeline realistic and your plans approvable.
7. Making Changes Mid-Construction
Changes after work begins are the fastest way to blow a budget and a schedule. Spend the time to finalize layouts, finishes, and fixtures before the first wall goes up.
