Quick answer

In Minnesota, a licensed contractor's estimate must be written and include a detailed summary of the work, the materials, and the total price or how it's calculated (Minn. Stat. 326B.809). Compare scope, not just price; check that allowances are realistic; get every change in a signed change order; keep the deposit small and hold back final payment until inspections pass; and collect lien waivers from subcontractors and suppliers before you pay in full.

What Minnesota law says an estimate must include

Every proposal, estimate, bid, contract and change order from a licensed Minnesota contractor must be in writing and include (Minn. Stat. 326B.809):

  1. A detailed summary of the work to be performed
  2. A description of the specific materials, or a list of standard features
  3. The total price, or how the price will be calculated

The contractor also has to give you written performance guidelines before you sign, and a signed, dated copy of every agreement and lien waiver at no charge. The contract must state the contractor's license number (326B.87).

Comparing bids

Allowances: the line that can move your price

An allowance is a budget placeholder for things you haven't picked yet, like tile, a vanity or light fixtures. NAHB's model contract describes allowances as amounts for fixtures and finishes that are selected by the buyer during construction, with any increase or decrease reflected on a signed change order (NAHB).

What to check: is each allowance realistic for what you actually want? A low allowance makes a bid look cheaper, then the difference shows up later. At cK Builders we spell allowances out in the estimate so there are no surprises.

Change orders

Minnesota law requires change orders to be in writing (326B.809). DLI says any change to the scope or price should be a written change order signed and dated by you and the contractor, and you get a copy when it's issued (MN DLI). The Attorney General adds that anything not in the contract can be treated as an extra that costs more, so get every promise in writing (MN AG).

Deposits and payment schedules

Liens and lien waivers

In Minnesota, subcontractors and suppliers who don't get paid can file a lien against your home, even if you paid your contractor. That's why every residential contract with subs or suppliers must include a state-required notice telling you about lien rights and your right to withhold payment until you get lien waivers (Minn. Stat. 514.011). Before final payment, get signed lien waivers from each subcontractor and supplier (MN AG, MN DLI). A contractor who's required to be licensed but isn't can't file a lien at all (MN AG).

License and insurance

Minnesota license numbers begin with BC (building contractor), CR (remodeler) or RR (roofer); numbers starting with IR are registrations, not licenses (MN DLI). Licensed contractors must carry liability insurance of at least $100,000 per occurrence and $300,000 aggregate for bodily injury, plus $25,000 property damage, and you can ask to see their workers' comp policy (MN AG). Hire licensed, and you're also eligible for the state Contractor Recovery Fund, which can pay up to $100,000 per owner if a licensed contractor commits fraud or fails to perform (326B.89, MN DLI).

Frequently asked questions

What should a contractor estimate include in Minnesota?
By law (Minn. Stat. 326B.809), it must be in writing with a detailed summary of the work, the specific materials or standard features, and the total price or how it will be calculated.
How much deposit should a contractor get?
Minnesota's Attorney General says a good-faith down payment is customary but should be no more than a small percentage of the job; DLI says a modest percentage. Avoid contractors who insist on a large down payment.
What is an allowance in a construction estimate?
A budget amount for items you'll choose later, like tile, fixtures or a vanity. If your selection costs more or less, the difference goes on a signed change order.
Do change orders have to be in writing in Minnesota?
Yes. Minn. Stat. 326B.809 requires change orders between a licensed contractor and customer to be in writing, and DLI says you should get a signed, dated copy.
What is a lien waiver?
A signed statement from a subcontractor or supplier giving up the right to file a lien against your property. Get them from each sub and supplier before making final payment.
Is the lowest bid the best bid?
Not necessarily. The Minnesota Attorney General warns an unusually low bid may be cause for alarm, and some contractors bid low and raise the price later for “unforeseen circumstances.”
