What happens if you skip the permit (and you needed one)
- Stop-work order issued by city inspector costs $250–$500 in citation fees, plus you'll owe double permit fees when you finally pull a retroactive permit.
- Homeowner's insurance may deny claims for unpermitted work; water damage, electrical fire, or gas leak discovered post-loss could leave you uninsured and liable for $20,000–$100,000+ in repairs.
- When you sell, Idaho Residential Property Condition Disclosure (RPCD) must disclose unpermitted work; buyer can back out, demand price reduction (typically 2–5% of sale price), or sue for non-disclosure.
- Lender (mortgage, HELOC, refinance) can demand removal or correction of unpermitted structural or mechanical work, potentially blocking loan close; some lenders require a licensed engineer's certification to accept it as-is, costing $1,000–$3,000.
Boise City full kitchen remodels — the key details
Boise City adopts the 2018 Idaho Building Code (IBC), which mirrors the 2015 International Building Code with Idaho-specific amendments. For kitchens, the triggering code sections are IRC E3702 (small-appliance branch circuits — two required, serving only countertop receptacles), IRC E3801 (GFCI protection on all countertop and sink outlets), IRC P2722 (kitchen-sink drain sizing and trap-arm slope), and IRC G2406 (gas-appliance connections and shutoff valve placement). Any remodel that involves moving or removing a wall, relocating a plumbing fixture, adding a new electrical circuit, modifying a gas line, or cutting an exterior wall for a range-hood vent crosses into the permit threshold. The city's Building Department interprets 'relocated' plumbing to include not just moving the fixture itself, but also rerouting supply lines or drain lines — even if the sink stays in the same corner, if you're reconfiguring the undersink cabinet or adding a new P-trap, that's a reportable change. This matters because plan review commonly rejects plumbing-relocation drawings that don't show trap-arm slope (1/4 inch per foot minimum, per IRC P3005.2), vent-stack connection detail, or undersink access clearances.
