Why Checking Zoning First Matters
78% of DIY ADU projects face unexpected setbacks because homeowners didn't verify zoning first. Here's what's at stake:
$15K Lost on Plans
A homeowner paid an architect $15,000 for custom ADU plans — only to discover their lot didn't allow ADUs at all.
Setback Surprise
Foundation was poured, then the inspector found a 5-foot setback violation. Tear-down cost: $32,000.
18-Month Delay
They needed a special permit but didn't know it. Town board meetings are quarterly — project delayed 18 months.
