A California homeowner has exactly 15 days after a remodel ends to file one form: a Notice of Completion [1]. File it, and a subcontractor’s window to place a lien on the house drops from 90 days to 30 [1]. Miss it, and a supplier the owner never even met keeps a 90-day clock running long after the final check clears [2].

The big picture:

Homeowners often treat a remodeling contract as the whole story.

The reality is that lien rules sit in state law, running entirely outside that contract. A subcontractor or a supplier who never gets paid by the general contractor can file a claim against the house itself. This happens even when the owner paid the general contractor in full.

State statutes set the timeline. California gives a claimant 90 days from completion to file [2]. Arizona allows 120 days, or 60 if a completion notice is on file [4]. Utah requires a subcontractor or supplier to file a preliminary notice within 20 days of starting work, or they lose the right to lien entirely [3].

The part I keep circling is that an owner’s protection has nothing to do with the contract price. It comes down to two paper acts. Record the completion notice on time, and hold the next payment until every claimant signs a release.

By the numbers

  • 15 days — The owner’s deadline: A California homeowner has 15 days from completion to record a Notice of Completion [1]. This filing cuts a subcontractor’s or supplier’s lien window from 90 days to just 30 [1].
  • 90 days — The default clock: Without a notice on file, a claimant must record the lien within 90 days of completion, acceptance, or first use [2]. A lawsuit to enforce that lien must follow within 90 days of recording [2].
  • 120 days — Arizona’s longer window: Arizona allows 120 days to record a notice and claim of lien after completion [4]. That window falls to 60 days once an owner records a completion notice [4].
  • 20 days — The early notice: Utah requires a subcontractor or supplier to file a preliminary notice within 20 days of starting work to keep their right to lien [3]. California runs the exact same 20-day early window [2].

What I’d watch:

Title officers, construction lawyers, and experienced general contractors track statutory dates, not just the contract price. Here is what I am watching next.

  • The completion notice: Recording this form is the cheapest defensive act a homeowner has [1]. California keeps the timing tight at 15 days [1]. I am watching how many owners skip this step simply because nobody told them it was their job to file it.
  • Releases at every payment: A conditional release protects the owner until the check clears, while an unconditional release means the payment is made and the claim is gone [1]. California’s licensing board notes the owner can legally hold the next payment until the prior releases are in hand [1].
  • State guaranty funds: Maryland caps recovery from its Home Improvement Guaranty Fund at $30,000 per claim, and limits one contractor’s total to $250,000 [5]. New York City pays up to $20,000 through a simple claim process, and up to $40,000 through its standard process [6]. Since both ceilings sit below the cost of a typical kitchen remodel, the fund is a backstop rather than a primary plan.
  • Who is allowed to lien: Laborers and the direct contractor usually skip the early notice [2]. Subcontractors and suppliers do not [2]. The group of people who can cloud a title is much wider than the crew the owner actually hired.

The catch

My read is that the rules cut both ways.

The exact same 15-day filing that protects a homeowner exists so a diligent supplier gets paid. If states shorten the clock too aggressively, builders grow wary of taking on small jobs [1][4].

The day-counts vary wildly, and they stay in motion. Arizona’s 120 days is not California’s 90 [1][4]. The money in a state fund is set by local statute, not by a national standard [5][6]. A homeowner in one state cannot safely rely on a timeline from another.

There is also a massive gap between what the law allows and what most owners do. Holding the next payment until releases arrive is perfectly legal [1]. Yet most people pay the last invoice in full and only hear about the lien months later. That is how a routine roof replacement turns into a five-month, four-figure legal cleanup.

At a glance

  • The Big Shift: On a home remodel, the money already paid does not end the owner’s risk. A subcontractor or supplier left unpaid by the general contractor can still lien the house, and the deadline runs on a strict state clock the owner has the power to shorten [1][2].
  • Why It Matters: The owner holds two controls, both cheap and both timed. Record the completion notice (15 days in California) to cut a subcontractor’s lien window from 90 days to 30, and release each payment only against a signed lien release [1][2]. Skip either, and a stranger’s unpaid invoice lands on the property title.
  • What I’d Watch:
  • The completion notice: Whether owners actually file it inside the 15-day window, since it is their responsibility and nobody else’s [1].
  • Releases at every payment: Whether each check goes out against a conditional release, and whether the next payment waits on the prior ones [1].
  • State funds: What a guaranty fund actually pays — $30,000 per claim in Maryland, up to $20,000 in New York City — against a remodel job that usually costs much more [5][6].
  • The Catch: The day-counts differ drastically by state (Arizona’s 120 days is not California’s 90), the fund caps are set locally and sit below a typical remodel, and shortening the clock too far pushes builders away from small jobs [1][4][5][6].
