Bonjour’s family budgeted $480,000 for the construction of the ADU. Of that total, they set aside $100,000 as a contingency fund.
“As a realtor, and as someone who’s always telling people to ask all the questions, I also hate to be caught by surprise,” Bonjour said. “With the contingency budget, you build in extra money that you hope you won’t need. It’s something everyone should consider, whether they’re building a million-dollar home or a small casita in the backyard.”
Unfortunately, unexpected costs, like hiring replacement contractors and installing a new electrical panel and solar panels, have exhausted the reserve. Bonjour said the extra expenses have trickled into the family’s day-to-day life, making it harder to justify things like family trips and upgrading the main home.
“I wish I had allocated it differently, but again, I think that planning with the right people at the onset would have saved so much headache and time,” she said. “We’ll have to wait on upgrading the home. That’s kind of annoying, but that’s where we’re at. Lesson learned on that one.”
