Two Idaho rules decide whether a construction job in Ada County ends in payment or in a claim. A construction lien attorney in Kuna confirms registration before anyone signs, then watches a ninety-day clock that starts when the work finishes rather than when an invoice is ignored.

Quick answer
Idaho Code section 45-507 allows ninety days after the labor or services are completed, or the materials furnished, to record a claim of lien. For a Kuna parcel that recording happens at the Ada County Recorder in Boise, which makes the last days of the window a logistics question too.
Construction is not a side activity in Kuna. Residential development, light industrial and distribution buildings, and the tenant improvements that follow them have been the town’s steady work since the population moved from 5,382 in 2000 to 24,011 at the 2020 census, and the same trades circulate between all three.
Payment disputes on those jobs almost never turn on craftsmanship. They turn on two Idaho rules that are simple to satisfy in advance and impossible to repair later: who may lawfully work as a contractor, and how long a claim of lien has to be recorded after the work ends.
Clark Meyers PC drafts and reviews prime contracts, subcontracts and supply terms for Kuna owners, general contractors and trades, and sets the registration and deadline checks up as a routine rather than a reaction.
Completion, for lien purposes, is the end of the claimant’s own labor, services or furnishing of materials rather than the end of the building. Each party therefore runs its own ninety-day period. A subcontractor that finished early can lose its lien right while the structure is still going up.
Payment slows, conversations continue, and the job drifts. By the time a claim is prepared, the one fact the statute turns on — the date this party’s scope ended — exists only in somebody’s memory, and the other side remembers a different date.
Daily logs, delivery tickets, signed change orders, inspection sign-offs and a dated final punch list turn completion into a record rather than a recollection. The contract can define it directly, which avoids the argument altogether.
Registration gets confirmed for the engaging party and for every trade brought on, with the evidence saved beside the signed subcontract. It is a short task that removes an argument nobody wants once money is already owed.
Idaho Code section 54-5204 makes it unlawful, on and after January 1, 2006, to engage in the business of a contractor or to hold yourself out as one in Idaho without being registered. The same section goes a step further: a contractor must not engage another contractor without proof of current registration.
That second duty is the one that catches people. On a Kuna job pulling framing, concrete, mechanical and electrical trades from across the Treasure Valley, the obligation to verify belongs to whoever is doing the engaging, and a gap downstream is not somebody else’s private affair.
Registration also expires. On a project running across a year, a check performed at engagement has become a stale answer by the time that trade comes back for punch work.
Section 45-507 requires a claim of lien to be recorded within ninety days after the completion of the labor or services, or the furnishing of materials. The trigger is the work itself. It is not the invoice date, not the rejection of a payment application, and not the day a working relationship soured.
That ordering runs against instinct, because a dispute feels urgent later than it actually began. A supplier whose final delivery landed in April and who is still exchanging polite emails in July may be out of time without having done a single thing wrong.
Kuna is an Ada County city and Ada County’s seat is Boise, so a claim of lien against Kuna land is recorded there rather than in town. On day eighty-eight that stops being trivia and becomes a scheduling constraint.
The same office holds everything already recorded against the parcel: the owner’s deed of trust, earlier liens, easements and plat restrictions. A search run before the contract is signed shows what a later claim would be standing behind.
A subdivision phase, a light industrial shell and a tenant improvement inside that shell can involve the same trades on overlapping schedules. Each party’s ninety days runs from its own last day, so one building can carry half a dozen live deadlines at the same moment.
Two habits keep that straight without much effort.
Each agreement gets its own completion date and its own diary entry, instead of a single project-wide date that everyone assumes applies to them. The assumption is usually wrong, and it is wrong in a direction that costs the claimant.
A short written confirmation that a trade’s scope is finished, signed and dated by both sides, removes the ambiguity the statute is measured against. It also makes retainage release easier to administer, so it earns its keep twice.
A lien secures payment against the land. It does not establish what is owed. The contract answers that, and the clauses doing the heavy lifting are the ones drafted in a hurry: payment timing, retainage and its release condition, the change-order route, the definition of completion, and the notice required before calling a breach.
On converted farm ground there is one more clause worth real attention. Old irrigation structures, buried debris, fill of unknown origin and shallow groundwater can change a scope after mobilization, and the agreement should say who prices that change and by what mechanism.
The cost difference between the two ends of this is stark. Verifying registration and tightening an agreement is a short engagement with a defined scope. Reconstructing a completion date afterward, from records nobody kept, is open-ended work performed against a clock that is already running.
Owners and contractors running several Kuna jobs at once usually set the checks up once, as a standing process each new project inherits, rather than rebuilding them whenever somebody remembers to ask.
| Rule | What it requires | When it is satisfied | What a miss costs |
|---|---|---|---|
| Contractor registration | Registration is mandatory under section 54-5204 for anyone doing business as a contractor in Idaho, and a contractor may not engage another without proof that its registration is current | Before signature, and again on jobs running longer than a year | Exposure reaches the engaging party as well as the unregistered trade |
| Claim of lien | Section 45-507 sets ninety days from completion of that claimant’s own labor, services or materials for recording the claim | Inside ninety days of that party’s last day, at the Ada County Recorder | The security against the property is gone, leaving an unsecured contract claim |

The two dates that decide a Kuna construction payment dispute are both set before anyone is arguing: the day registration was confirmed and the day that scope of work ended. Put both in the contract and the project file, and the ninety-day right is still there when it is needed.
The ninety-day period under Idaho Code section 45-507 begins when the claimant’s own labor, services or materials end, which is frequently weeks before anyone treats the payment dispute as serious.
Claims of lien against Kuna property are recorded with the Ada County Recorder in Boise, because Kuna is an Ada County city and the county seat is where land records are kept.
Idaho Code section 54-5204 bars a contractor from engaging another contractor without proof of current registration, so the verification duty belongs to whoever is doing the engaging on a Kuna job.
Each claimant measures the ninety days from the end of its own scope, so a concrete subcontractor that finished in spring and an electrician still working in midsummer are on separate deadlines.
Once the statutory window closes, the security against the property disappears and the unpaid party is left pursuing an unsecured contract claim against whoever actually signed the agreement.
Registration expires on its own schedule, so a verification performed when a trade was engaged can be out of date by the time that trade returns for punch list work months later.
Dated daily logs, delivery tickets, signed change orders, inspection sign-offs and a final punch list are what establish a completion date, and they have to be kept while the job is running.
A lien secures payment against the land, while the amount owed, the payment schedule and the consequences of paying late all come from the contract the parties actually signed.
Verifying registration and tightening a contract is a short engagement with defined scope, while reconstructing a completion date after the fact is open-ended work performed against a deadline already running.
Construction matters on Kuna projects are run from the Clark Meyers PC office in Nampa at 4865 E. Franklin Rd, and the firm keeps no separate office inside Kuna.
