What Documents Should I Ask For When Hiring A Contractor? Complete Checklist for Property Managers

The break room at Johnson Construction has a whiteboard. Written across the top in permanent marker: “No Document = No Work.” Below it, tally marks track saved lawsuits—247 and counting.

According to the National Insurance Crime Bureau, post-disaster contractor fraud alone costs Americans up to $9.3 billion annually¹. Construction fraud cases can result in median losses of $250,000 per incident² according to the Association of Certified Fraud Examiners. Proper documentation significantly reduces these disasters when hiring a contractor.

Key Takeaways

• Essential Documentation: Collect 25+ critical documents across three categories: verification (licenses, insurance), project (contracts, permits, warranties), and protection (lien waivers, completion certificates).
• Insurance Requirements: Demand general liability coverage with at least $1 million per occurrence and $2 million aggregate limits³, plus workers’ compensation and commercial auto insurance of at least $1.5 million⁴.
• Payment Protection: Never pay more than 10% down, tie all payments to milestones, and exchange lien waivers simultaneously with payments.
• Permit Responsibility: Always have contractors pull permits—whoever pulls becomes the legal contractor with full liability.
• W-9 Requirement: Collect W-9 forms before paying—the IRS requires 1099 filing for contractor payments over $600⁵.
• Red Flags: Walk away from contractors who can’t produce documents immediately, offer cash discounts to skip paperwork, or claim permits aren’t needed.
• Professional Management: Consider professional incident management for major projects or emergency restoration to ensure complete documentation compliance.

Miss even three of these contractor documents? You’re gambling with your largest investment.

Why Each Document Can Save You Thousands

Verification Documents: Your First Defense Line

The License That Isn’t

Every contractor has a laminated license card. That card might be expired, suspended, or fake. State licensing boards suspend licenses daily for insurance lapses, violations, or unpaid judgments. The contractor showing you last year’s card doesn’t mention his suspension last month.

Action: Write down the license NUMBER. Verify it yourself at your state’s contractor board website before continuing any conversation. Takes three minutes. Saves potential heartbreak.

The Insurance Certificate Trap

Here’s what contractors won’t tell you: Their general liability insurance probably excludes your specific project type. Roofing policies often exclude flat roofs. Remodeling policies might exclude structural work.

There’s a bigger trap. That million-dollar policy protects the contractor, not you—unless you’re named as “additional insured.” Without that endorsement, you’re just another claimant fighting for coverage.

Action: Request additional insured status in writing. Call the insurance company directly (use the number from their website, not the certificate) to confirm coverage. If they won’t confirm, walk away.

Workers’ Comp: The Hidden Liability Bomb

“I don’t need workers’ comp—I work alone.”

When solo contractors say this, you relax. Mistake. That “solo” contractor brings a helper for heavy lifting. The helper falls off your roof. Guess who gets sued?

Even legitimate exemptions don’t protect you. In most states, an injured worker can bypass workers’ comp exemptions and sue you directly. Your insurance might deny the claim because you “hired” someone without proper coverage.

Action: Demand workers’ comp certificates or signed acknowledgment of YOUR liability exposure. No exceptions for “just me and my buddy” operations.

Project Documents: Your Control System

The Contract That Actually Protects You

Legitimate contracts contain unglamorous specifics that matter when problems arise:

• Start date with penalty for delays (typically $100-200/day)
• Completion date with weather delay provisions
• Payment schedule never exceeding 10% down (unless custom materials require more, documented separately)
• Specific materials by brand and grade (not “industry standard”)
• Change order process requiring written approval
• Lien waiver requirements tied to payments
• Who cleans up daily (and defines “clean”)

A contract missing any three of these elements isn’t protecting you.

The Permit Predicament

“Don’t worry, we don’t need permits for this.”

“You’ll save money if you pull the permits.”

“Permits just slow everything down.”

Three lies that destroy property sales and insurance claims. Unpermitted work creates serious sale complications. Insurance companies can deny claims for unpermitted improvements. Cities issue stop-work orders and daily fines.

Here’s the critical part: Whoever pulls the permit assumes contractor liability responsibilities. When you pull permits to “save money,” you become legally responsible for code compliance, inspection failures, and liability. The actual contractor becomes your “helper” with reduced legal obligations.

Action: Contractors pull permits. Period. If they resist, they’re planning to cut corners that inspectors would catch.

Protection Documents: Your Financial Armor

Lien Waivers: The Most Important Papers You’ll Never Frame

A contractor builds your deck. You pay in full. Six weeks later, the lumber yard files a lien because the contractor never paid them. Legal? Absolutely. Preventable? Completely.

Even following guidelines doesn’t ensure dispute-free projects, but proper documentation significantly reduces risks. Lien waivers work like receipts, but most property managers botch the timing:

• Conditional waiver: Exchange simultaneously WITH payment
• Unconditional waiver: Exchange AFTER payment clears (5 business days minimum)

Give an unconditional waiver before the check clears? You just gave up your only protection against disappeared contractors.

The Subcontractor Gap

Your general contractor’s insurance covers their mistakes. It doesn’t cover the subcontractor who installed your windows wrong. That requires separate documentation from every sub on the property.

Most property managers never meet their subcontractors, let alone document them. Then the unlicensed electrician burns down the kitchen, and the general contractor points to the fine print: “Subcontractors are independent businesses.”

Action: Demand a subcontractor list with insurance certificates before work begins. No surprise “helpers” or “specialists” appearing without documentation.

Red Flags That Scream “Run Away”

The worn spot on a contractor’s truck floor beneath the driver’s seat tells you something. They’re in that vehicle constantly. Successful contractors wear out trucks, not excuses.

Watch for these documentation dodges:

“I’ll bring that tomorrow” – Tomorrow never comes. Legitimate contractors carry standard documents.Learn more about incident management reporting systems

“My insurance guy is getting that” – Insurance certificates generate instantly online. This is stalling.

“We’ve never needed that before” – They’ve never been caught before. You don’t want to be the first.

“Cash discount if we skip the paperwork” – Tax evasion plus zero legal protection. The “savings” won’t cover the lawsuit.

“Trust me, I’m bonded” – Bonds are public record. If they can’t produce documentation immediately, they’re not bonded.

Your Action Plan: The Professional’s Approach

Property managers who never have contractor problems follow this sequence:

Before First Contact

• Verify license status online
• Check court records for lawsuits
• Review registration status (LLC/Corporation)
• Screenshot everything (licenses expire, websites change)

First Meeting (Documentation Review)

Spread their documents on a table. Photograph everything. Check:

• License numbers match online records
• Insurance dates are current (not “about to renew”)
• Business names match exactly across documents
• Phone numbers are working businesses (call them)

Before Signing

• Additional insured endorsement in hand
• Permit applications completed
• Subcontractor list provided
• Payment schedule defined
• Lien waiver schedule agreed

During Work

• Conditional waivers with every payment
• Change orders before additional work
• Progress photos (dated)
• No cash payments without notarized receipts

Project Completion

• Final unconditional lien waiver
• Every subcontractor lien waiver
• Warranty documentation
• Permit sign-offs
• Certificate of completion

This isn’t paranoia. It’s the professional standard that helps prevent substantial losses.

Documentation Most Contractors Don’t Mention

The W-9 Tax Form

The IRS considers you a business when you hire contractors. According to IRS requirements⁵, if you pay someone who is not your employee $600 or more for services during the year, a Form 1099-NEC needs to be completed. The contractor who “forgot” the W-9 might be planning to “forget” reporting the income.

Photo Documentation Agreement

Smart contracts include photo provisions: contractors document pre-existing conditions, progress milestones, and completion. When they claim your foundation crack was pre-existing, their own photos prove otherwise.

The Arbitration Clause

Buried in many contracts: mandatory arbitration. You can’t sue, only arbitrate. Construction arbitration⁶ often involves tiered dispute resolution including management discussions and expert resolution before reaching arbitration. Arbitration can cost thousands upfront, may favor contractors, and eliminates jury trials. Cross out arbitration clauses or find contractors who don’t require them.

When Professional Management Makes Sense

Documenting contractors properly requires expertise. Missing one critical document among the requirements creates expensive vulnerability.

Professional incident management companies handle this documentation daily. They know which certificates are fake, which insurance companies are reliable, and which licensing boards actually investigate complaints. For major projects or emergency restoration work, professional oversight costs far less than a documentation mistake.

FIRM manages contractor compliance for property owners nationwide. When disasters strike and contractor documentation becomes critical, professional incident management protects your interests. Before your next major project or emergency restoration, consider whether professional contractor oversight makes sense.

Final Thoughts on Contractor Documentation

Those 247 tally marks in Johnson Construction’s break room? Each represents a prevented disaster through proper documentation. Not one represents paranoia or overthinking.

Every missing document is a door left unlocked. Contractors know which property managers check documentation and which don’t. They adjust their behavior accordingly.

Your document checklist isn’t bureaucracy. It’s the difference between a successful project and a financial disaster. Between a warranty claim honored and denied. Between a lien-free property and an unsellable house.

The worn spot on that break room floor? It’s from the office manager’s chair, rolling between the filing cabinet and copy machine, creating duplicate documentation sets for every project. That’s what professionals do. That’s what protects you.

Start your documentation file before you make the first call. Because once work begins without proper papers, you’re not hiring a contractor—you’re gambling with the property.
