Getting paid on a construction project can be hard work. There are a lot of documents that construction businesses need to exchange in order to receive payment. One of the most underrated documents in construction is the preliminary notice, an informational document sent at the start of a project. It brings enormous benefits to everyone involved in a project, from the property owner down to the smallest equipment supplier. Sending preliminary notice is a critical first step for anyone hired to work on a construction job.

This comprehensive article will explain everything you need to know about preliminary notices, why they鈥檙e so important, and best practices for everyone on a construction project.

What is a preliminary notice?

A preliminary notice is a document used on construction projects to provide information to the people in charge (like the property owner and general contractor) about the work being performed. In many states, contractors and suppliers must send preliminary notice to retain the right to file a mechanics lien or make a bond claim if they are unpaid.

Preliminary notices go by a lot of different names:

  • Notice to owner (NTO)
  • Notice of furnishing
  • Prelim
  • Pre lien
  • And many more…

The construction industry uses a variety of notices, but preliminary notices are special – some might even say 鈥渕agical.鈥 One look at the 鈥 gives you an idea of how powerful they are:

鈥渄enoting an action…done in preparation for something fuller or more important.鈥

And indeed, preliminary notices are used in preparation for something more important. In fact, it鈥檚 the reason why any construction business exists in the first place: Payment.

As you might have guessed, preliminary notice is sent at the beginning of a project, or at least within a few days  after work begins.

Why are preliminary notices important?

It all comes back to payments – making them and receiving them. At the end of the day, everyone who works on a construction project wants the same things: to complete the project successfully, and to ensure that everyone gets paid.

It might seem counterintuitive to suggest that property owners want everyone to get paid. You might be thinking, 鈥淲ouldn鈥檛 the property owner rather not pay anyone?鈥 Of course, everyone financing a construction project wants to minimize their costs. But they also want to avoid legal claims against their property, known as mechanics liens.

Property owners want to avoid claims on their property

A mechanics lien is a legal document that unpaid construction businesses can use to essentially freeze the property. And the people in charge of a project definitely don鈥檛 want that to happen. Unfortunately, the complexity of construction projects can create a huge risk for the owners. If they don鈥檛 know who is working on their property, they can鈥檛 make sure that everyone gets paid. And if someone doesn鈥檛 get paid, they have the right to file a mechanics lien against the property.

In fact, property owners are largely responsible for the existence of construction notices! In the 1960s and 70s, property owners and construction lenders lobbied state governments to help them protect against the problem of 鈥渟urprise liens.鈥 This lobbying led many states to create laws requiring preliminary notices. The purpose was to give owners and lenders the ability to identify and track the contributors to the job, so that they could pay everyone and proactively avoid lien claims.

Preliminary notices are necessary because a construction project is an expensive, complex, and often risky undertaking. The number of people required to complete a project grows exponentially as the project size increases. For property owners and lenders, these notices help make sure they know everyone who鈥檚 working on their project.

Subcontractors & suppliers want to get paid on time

Sub-tier parties, like subcontractors and suppliers, also want to avoid mechanics liens, but for a different reason: They would much rather get paid in full and on time for their work, so they can move on to the next project.

Sending preliminary notices helps sub-tier parties get paid. This is because sending the notice brings their contribution to the attention of the owner, and other people in charge of payments. When the owner knows that a particular company is working on their property, they can take steps to make sure they collect what they鈥檙e owed.

Benefits of preliminary notice

Even though they largely help with managing payment on a construction project, preliminary notices bring a number of benefits that reach well beyond a checkbook. They improve communication, send professional signals, help GCs with waiver collection, and can correct an imbalance of power.


One of the biggest benefits preliminary notices bring to a construction project is improved communication. General contractors have a difficult job of coordinating everything that happens on a project, from coordinating subcontractors to navigating design changes to ensuring smooth and timely payment. Managing a successful project requires a high level of communication with everyone involved, from the architect down to the sub-subcontractors and material suppliers.

While the GC probably knows how to contact the architect, they might not know how to get in touch with the electrician who was hired by a sub-subcontractor. This is a problem when the architect issues a change order, and the GC has to shift the production schedule around. The electrician needs to know about the schedule change, too. Sending preliminary notice ensures that the GC knows he鈥檚 on the job, giving the GC the ability to notify him about important project changes or delays.


In the construction industry, relationships and reputation matter. Everyone wants to hire the most professional outfit to get each part of the job done.

Most property owners and GCs probably have a recurring nightmare that involves a sloppy subcontractor who does shoddy work, doesn鈥檛 communicate about what they鈥檙e doing, and quits the job as soon as their check clears.

Sending a preliminary notice sends a strong signal to the hiring party that they鈥檙e working with a professional. When a property owner receives a notice, they know that the company has its processes and procedures in place, understands the value of communication, and runs a tight ship.

Improved lien waiver collection

General contractors generally need to collect lien waivers from every party on the project in exchange for payment. But identifying everyone who needs to send waivers – and making sure they collect, organize, and track all of the waivers – can be a difficult task. Preliminary notices help avoid headaches when the time arrives for payment. If they collect prelims from every party, they can easily match waivers to them, and make sure that everyone is accounted for.

Balancing risk

A big part of managing a construction project successfully is balancing risk. Preliminary notices help property owners reduce the risk of double payments, and help subcontractors reduce the risk of non-payment. In most states, contractors and suppliers are required to  send preliminary notice if they want to protect their right to file a mechanics lien or bond claim later on.

Preliminary notice and the mechanics lien process

A mechanics lien is a powerful tool that contractors and suppliers can use if they don鈥檛 receive payment. But it doesn鈥檛 just happen automatically. In general, there are 3 required documents that make up the mechanics lien process:

  1. Preliminary notice
  2. Notice of intent to lien
  3. Mechanics lien

Of course, no one starts a project expecting not to get paid. Too many contractors put themselves in a bad situation because they didn鈥檛 think they needed to send preliminary notice – until it was too late.

Unfortunately, that scenario plays out all too often. There are a lot of moving parts that have to line up just right for payments to flow down the chain of contractors and suppliers on a job. Problems occur all the time – but there鈥檚 no way to predict when and where they will arise.

That鈥檚 why sending a preliminary notice on every single project is simply good business. If it鈥檚 not required in your state…send a preliminary notice. When you don鈥檛 expect a payment problem…send a preliminary notice. If you鈥檙e doing a roofing job on your best friend鈥檚 house…send a preliminary notice.

State requirements

In states where preliminary notice is required to protect your lien rights, you鈥檒l need to follow specific requirements. These include sending notice in a specific timeframe,  to the right people, by the proper means, and providing complete and accurate information.

However, because of the enormous benefits they provide, it鈥檚 a good practice to send prelims even if your state doesn鈥檛 require it.

Calculating your deadline

Each state sets their own deadline, and some are stricter about it than others. In California and Arizona, for example, you must send preliminary notice within 20 days of first furnishing labor or materials. But if you miss the deadline, you鈥檙e not dead in the water. You can still send one – but the lien protection will be limited to the labor or materials provided 20 days prior to the notice and everything thereafter.

In many other states, the deadline is hard and fast. Failing to send a preliminary notice within the timeframe required means you give up your right to file a mechanics lien entirely. If you don鈥檛 get paid, your options to recover payment are much more limited, expensive, and time-consuming.

It鈥檚 a good idea to send a prelim as soon as you start any project. This will prevent you from needing to calculate deadlines in different states or on different projects. You can always rest assured that your lien rights are protected.

Information to include on a preliminary notice

While it鈥檚 important to check your state鈥檚 specific requirements, there is some information that preliminary notices will generally contain:

In addition, many states with preliminary notice requirements also require specific notice language on the form that informs the recipient of your right to file a lien if they don鈥檛 pay you on time.

Delivering preliminary notice

Most states spell out exactly how preliminary notices can be sent. The best practice is to deliver notice by certified mail with return receipt requested, so that you have a record of the service in case a disagreement arises down the road. States often allow for personal service, i.e. hand delivery, but that can be harder to prove.

Most often, you鈥檒l need to serve notice on the property owner (that鈥檚 why quite a few states call it a Notice to Owner). In some cases you鈥檒l need to provide it to the general contractor and, potentially, the lender, depending on the state, project type, and project role.

Regardless of the requirements, it鈥檚 a good idea to send notice to all of the parties up the payment chain. You can鈥檛 really send preliminary notice to too many people. The more people who know you’re on the job, the more likely you are to receive payment on time.

Project Awareness Letter

A project awareness letter is a type of non-statutory preliminary notice. This means that there aren鈥檛 any laws that govern how or when to send it, and it won’t affect your lien rights. It鈥檚 a document that gives information to the parties above you about your company. It includes a description of the work that you鈥檙e doing, and the contract price you鈥檙e working for.

Fundamentally, there鈥檚 really no difference between an awareness letter and a prelim. The main difference is that, in preliminary notice states, that information must be delivered in a specific format, by a specific deadline, and in a specific way. In fact, some states require a prelim to contain a statement like 鈥淭his is an informational notice required by law.鈥

Construction businesses in states without a statutory preliminary notice may use a project awareness letter instead. While they don鈥檛 carry the same legal weight, they include  all of the same information. Providing an awareness letter improves communication, provides more transparency, and improves the likelihood of on-time payments in full.

Preliminary notice vs. other construction notices

Construction has a lot of different types of notices that relate to the payment process. Each state has their own names for them. The whole process can feel a lot more complicated than it really is.

It helps to think of a preliminary notice as one that construction businesses send to provide information to the people in charge at the beginning of a construction project. That鈥檚 the big difference between this and other types of notices.

Consider the Notice of Intent to Lien (NOI), for example. This is a document that鈥檚 sent before a mechanics lien can be filed in some states. It鈥檚 only used after a payment has been missed. So it doesn鈥檛 make sense to send it at the beginning of a project.

A Notice of Commencement is another type of notice used at the beginning of a construction project. But it’s not used by a contractor or supplier. This document is filed by the property owner (or sometimes the GC) to serve as a public record that a project has started.

In certain cases, states may also require you to actually file a preliminary notice with the county clerk. But that鈥檚 not typical.

Best Practices For Preliminary Notices

Below are some best practices for property owners, general contractors, and sub-tier construction parties to use preliminary notices to their respective advantage. If you want to dig deeper, try this free download: The Guide to Best Practices for Preliminary Notices.

What Property Owners Can Do

It can be difficult for property owners to identify everyone on their project and make sure they鈥檙e paid. And that difficulty can lead to missed payments…which can lead to mechanics lien claims. So preliminary notices can actually be incredibly helpful. Owners and GCs should love receiving preliminary notices!

Because of this, it鈥檚 a good idea to put a preliminary notice requirement in your contract with the general contractor. Make collecting notices a concrete, requisite part of the process. This process is a critical part of avoiding lien or bond claims.

If you鈥檙e a property owner, the main thing to do when you receive a preliminary notice from a contractor or supplier is to keep a record of it. Establish a process to collect and organize all of the preliminary notices you receive. Or ask the GC to establish this process, and present it to you with the pay applications. (Even better if you both have a process, so you can compare your records as an added level of protection.)

When it comes time to submit payments, you can use these records to double-check pay applications and track that payments are going to the right people.

What General Contractors can do

General contractors have a more complicated relationship with preliminary notices. While they receive them from sub-tier parties, GCs must often send prelims in order to protect their own lien rights as well.

When it comes to managing a project, general contractors and property owners often have the same interests: Finishing the project on time and avoiding lien claims from sub-tier parties. They also have the same problem: It鈥檚 hard to see everyone who鈥檚 working on a project, much less collect prelims from all of them. Worrying about mechanics lien claims keeps a lot of GCs and property owners up at night.

So wouldn鈥檛 it be better to ask subs and suppliers not to send preliminary notice, so they don鈥檛 have lien rights in the first place? That鈥檚 the solution that some GCs come up with, but it鈥檚 a really bad one.

First of all,  a GC can鈥檛 legally prevent someone from sending a notice. Sure, you can use your leverage to bully them into submission – but you鈥檒l quickly find that subcontractors (and property owners) don鈥檛 want to work with you.

And second, this ignores the actual benefits that preliminary notices provide (see above). A much better solution is to require prelims from every single party on the project. Put it in your subcontracts – that the subcontractor must get all of their subs and suppliers to send preliminary notices, too.

The more visibility you have into who is working on your project and the work they鈥檙e doing, the better you will be at ensuring payment to all of them. This protects you (and the property owner) against non-payment claims.

Collect & track notices effectively

On most projects, the task of actually collecting and tracking preliminary notices from every sub, sub-sub, and supplier will fall to the GC. The best way to manage this process is to use a system to track which parties on a project have provided a preliminary notice, and when those parties sent the notice.

Whether this process involves a waiver tracking spreadsheet you manage in-house or a software platform that does the tracking automatically is up to you. But if you just receive preliminary notices without giving any thought to connecting them to the party that sent them, you can lose the benefits that they bring.

What subcontractors & suppliers can do

Believe it or not, you have the same goals as the property owner and GC, too: You want to avoid a mechanics lien or bond claim. You鈥檇 much rather get paid fairly for your work so you can invest that money in other projects.

Sending preliminary notice is a really important step to achieving this goal. Construction companies that send a prelim are more likely to get paid in full and on time – without ever having to file a claim for non-payment.

As soon as you sign a contract, you should put the steps in motion to send your preliminary notice. Identify the information you need to complete the notice, and send a request to the GC and/or property owner to make sure you have everything you need. This information will be useful for other documents as the project progresses, so it鈥檚 a good idea to keep it in one place, like a project information sheet.

The main takeaway for sub-tier parties is this: Send preliminary notice on every single project. Don鈥檛 waste time trying to figure out the risks of non-payment on each project, so that you only send notice on 鈥減roblem jobs.鈥 You might get the calculation right, but you won鈥檛 get it right every time.

Just establish a policy of sending a prelim every single time, as soon as your work on the project begins. This will protect your lien rights when you need them, but in the majority of cases it will ensure you get paid what you鈥檝e earned; on time and in full. After all,  isn鈥檛 that the goal?
