How Much Deposit Can a Contractor Ask For in Idaho?
Idaho law controls who may work as a contractor and prohibits unconscionable and deceptive practices in trade or commerce, but the provisions cited here set no dollar cap on the deposit a contractor may request.
Idaho does not have a statute that caps how large a deposit a contractor may ask for before starting work. Instead, the rules that bear on a deposit come from the Idaho Contractor Registration Act, which governs who may lawfully act as a contractor, and from the Idaho Consumer Protection Act, which forbids unconscionable and deceptive conduct in trade or commerce. Knowing these rules helps you judge whether a large upfront demand comes from a properly registered contractor and whether the surrounding conduct is lawful.
Rules that bear on your deposit
Before you hand over any money, it is worth confirming that the person you are hiring may lawfully do the work, because Idaho law makes it unlawful for any person to engage in the business of, or hold himself out as, a contractor within this state without being registered as required in this chapter. 1
Not every job triggers that requirement, since Idaho law provides that registration is not required for a person performing work on one undertaking or project considered casual, minor, or inconsequential whose aggregate contract price, for labor and materials and all other items, is less than two thousand dollars ($2,000). 2
Registration status also affects a contractor's remedies, because Idaho law provides that a contractor who is not registered as set forth in this chapter, unless otherwise exempt, is denied and deemed to have conclusively waived any right to place a lien upon real property. 3
Acting as a contractor carries consequences either way, since Idaho law provides that any person who engages in the business or acts in the capacity of a contractor, whether or not duly registered, has thereby submitted to the jurisdiction of the state of Idaho. 4
Separately, Idaho law provides that any unconscionable method, act or practice in the conduct of any trade or commerce violates the provisions of this chapter whether it occurs before, during, or after the conduct of the trade or commerce. 5
In weighing whether conduct is unconscionable, Idaho law provides that one circumstance a court considers is whether the price grossly exceeded the price at which similar goods or services were readily available in similar transactions by similar persons, although price alone is insufficient to prove an unconscionable act. 6

Frequently asked questions
- Does Idaho cap how much deposit a contractor can ask for?
- No. Idaho statutes do not set a fixed dollar amount or percentage limiting the deposit a contractor may request. Idaho law instead requires most contractors to be registered, denies lien rights to unregistered contractors, and prohibits unconscionable and deceptive acts in trade or commerce, which can bear on an unfair or grossly excessive upfront demand. Review the written contract and confirm registration before paying a deposit.
