How to Choose a General Contractor in Boise, Idaho
Hiring the wrong general contractor is one of the most expensive mistakes a Treasure Valley homeowner can make. A bad hire can mean blown budgets, months of delays, and work that has to be torn out and redone. This guide gives you a clear process for finding and vetting a contractor you can trust.
Quick Answer
Verify Idaho contractor license → check insurance certificate → get 2–3 written itemized bids → call local references → review the contract carefully before signing. Never pay more than 20–30% upfront. Never skip the permit.
Step 1: Verify Licensing and Insurance
This is the most important step and takes less than 10 minutes.
Idaho Contractor License
Idaho requires any contractor doing work over $2,000 to hold a license from the Idaho Division of Building Safety. Ask for the license number upfront and verify it at the state's online portal. If a contractor hesitates or can't produce a number, stop there.
General Liability Insurance
Request a certificate of insurance (COI) showing active general liability coverage with your name as certificate holder. This protects you if the contractor's work damages your home. Minimum $1 million in coverage is standard.
Workers Compensation
If the contractor has employees, they must carry workers compensation insurance. Without it, you could be liable if a worker is injured on your property. Sole proprietors with no employees may be exempt — verify this explicitly.
Subcontractor Verification
Ask how the GC handles subs. Do they use the same electrician and plumber consistently? Are those subs licensed? General contractors are responsible for the work of their subs — a good one knows and vets everyone on the job.
Step 2: Get and Compare Bids
Get at least two, preferably three written bids for any job over $5,000. Compare line by line — not just the total.
| What to Compare | Watch For |
|---|---|
| Total price and payment schedule | Large upfront deposits (>30%) or calendar-based payments |
| Specific materials and brands listed | Vague "allowances" that shift cost risk to you |
| Permit inclusion | Missing permit line — permits are always the contractor's job |
| Demo and disposal included | Some contractors exclude haul-away; clarify upfront |
| Labor and subcontractor breakdown | Unusually low labor may signal unlicensed workers |
| Warranty on labor | Good contractors offer 1-year minimum on their work |
Step 3: Review the Contract
Your contract is your protection if anything goes wrong. Every item below should be explicitly addressed before you sign.
If a contractor says "we don't do formal contracts for small jobs" — that's a red flag for any job over $2,000.
Red Flags to Walk Away From
⚠ Pressure to Sign Immediately
"This price expires today" is a sales tactic, not a capacity constraint. A reputable contractor will give you time to review a bid. If you feel pressured, walk away.
⚠ Significantly Lower Bid Without Explanation
A bid that's 30–40% lower than others usually means: missing scope, cheaper materials, unlicensed labor, or no permit included. Ask them to explain every line where they're cheaper.
⚠ Cash Only or Large Upfront Deposit
Legitimate contractors accept checks and typically request 10–20% upfront. Cash-only arrangements and 50%+ deposits are red flags. You lose leverage once the money is gone.
⚠ Can't Provide License or Insurance
This is disqualifying. Every Idaho contractor doing work over $2,000 must be licensed. Every legitimate business carries insurance. If they can't produce these documents, move on.
⚠ Offers to Skip the Permit
Skipping permits means the work won't be inspected, may not meet code, and can create serious problems when you sell. It also voids most homeowner's insurance policies for related claims.
5 Questions to Ask Every General Contractor
“Can you give me your Idaho contractor license number?”
Why ask: So you can verify it independently before any money changes hands.
“Who will be on-site daily — you, a foreman, or subs?”
Why ask: Tells you how much oversight there will be and whether you'll ever see the GC after contract signing.
“Can you provide 2–3 recent local references I can call?”
Why ask: Past clients are the best predictor of what working with a contractor is actually like.
“How do you handle change orders?”
Why ask: Changes are inevitable. You want a clear written process before they happen, not a surprise on the final invoice.
“What's your warranty on labor, and how do I contact you if there's an issue?”
Why ask: Establishes accountability after the job is done — and tells you if they plan to still be in business.
