Property managers in Orange County deal with contractors constantly — for painting, repairs, tenant improvements, parking lot work, plumbing, and dozens of other recurring needs. The best property managers have a consistent vetting process that protects their properties, their tenants, and their own professional reputation. Here are the questions they ask — and the answers you should expect from a qualified contractor.

This is always the first question. In California, contractors must hold a valid license from the Contractors State License Board (CSLB) for the type of work they perform. The relevant licenses for most commercial property work:

• B (General Building Contractor): General construction, tenant improvements, renovations
• C-33 (Painting & Decorating): Painting, wallcovering, surface preparation
• C-36 (Plumbing): Plumbing installation and repair
• C-10 (Electrical): Electrical installation and repair
• C-20 (HVAC): Heating, ventilation, and air conditioning

What to do: Verify the license number at cslb.ca.gov. Confirm the license is active, the classification matches the work, and the name on the license matches the contractor.

Red flag: Any contractor who can't provide a license number immediately, or whose license is expired, suspended, or in a different name than the company you're dealing with.

A licensed contractor should carry two types of insurance:

General liability insurance protects you if the contractor's work causes property damage or bodily injury. For most commercial property work, require a minimum of $1 million per occurrence and $2 million aggregate. The certificate should name you (the property owner or management company) as an additional insured.

Workers' compensation insurance covers the contractor's employees if they're injured on your property. Without it, you may be liable for injured workers' medical costs and lost wages.

What to do: Request certificates of insurance before work begins. Verify the certificates are current (not expired) and that the coverage limits meet your requirements.

Red flag: A contractor who says they're "exempt" from workers' comp but has employees working on your site. Sole proprietors with no employees can legitimately file an exemption, but any contractor with workers needs active coverage.

Many contractors bid work themselves but subcontract the actual labor to others. This isn't inherently a problem — it's standard practice in construction — but you need to know:

• Will the contractor's own employees perform the work, or will it be subcontracted?
• If subcontracted, are the subcontractors licensed and insured?
• Who is the on-site supervisor, and how much experience do they have?
• Will the person you're meeting with during the bid process be involved in the actual project?

What to expect: A transparent answer about the project team. A reputable contractor will tell you exactly who will be on site and in what capacity.

Red flag: Vague answers about who will do the work, or a contractor who seems to be bidding work they have no capacity to perform themselves.

References are one of the most valuable vetting tools available, and they're underused. Ask for references from:

• Projects of similar type (office building painting, retail TI, parking lot work)
• Projects of similar scale
• Projects completed in the last 1–2 years

When you call references, ask specifically:

• Did the contractor complete the work on schedule?
• Were there any significant cost overruns? How were they handled?
• How was communication throughout the project?
• Were there any quality issues? How were they resolved?
• Would you hire this contractor again?

What to expect: A contractor with a strong track record will provide references readily and encourage you to call them.

Red flag: Reluctance to provide references, references who give vague or lukewarm responses, or references who can't be reached.

Scope clarity is essential to avoiding disputes and cost overruns. Before signing any contract, make sure you understand exactly what is and isn't included.

For a painting project, for example, ask:

• Does the price include surface preparation (pressure washing, scraping, caulking, priming)?
• What products will be used, and how many coats?
• Is masking and protection of windows, landscaping, and tenant signage included?
• What is the warranty on labor and materials?

For a tenant improvement project:

• Does the price include permit fees?
• What trades are included (framing, drywall, electrical, plumbing, flooring, painting)?
• What allowances are included for fixtures and finishes, and what happens if selections exceed the allowance?
• How are change orders handled?

What to expect: A detailed written proposal that specifies scope, products, exclusions, and payment terms.

Red flag: A vague proposal with a single lump-sum price and no detail about what's included. This is a setup for disputes and change orders.

Changes happen on almost every construction project. The question is how they're managed. A professional contractor:

• Documents all changes in writing before performing additional work
• Provides a written change order specifying the additional scope and cost
• Gets your signature before proceeding
• Maintains a running log of approved change orders

What to expect: A clear, written change order process described in the contract.

Red flag: A contractor who performs additional work without written authorization and then presents a surprise invoice at the end of the project.

A reputable contractor stands behind their work. For painting, a reasonable warranty is 2–5 years on labor (peeling, flaking, or adhesion failure due to workmanship). For construction work, California law provides a 10-year statute of repose for latent defects and a 4-year period for patent defects.

What to expect: A written warranty specifying what is covered, for how long, and what the contractor will do if a warranty claim arises.

Red flag: No written warranty, or a warranty that excludes virtually everything.

Payment schedules should be tied to project milestones, not arbitrary dates. A reasonable structure:

• Deposit: 10–20% at contract signing (never more than 10% or $1,000, whichever is less, for residential projects under California law)
• Progress payments: Tied to completion of defined milestones
• Final payment: 10% held until final inspection, punch list completion, and receipt of lien releases

Red flag: A contractor who demands 50% or more upfront, or who wants full payment before the job is complete.

For occupied commercial properties, tenant disruption is a real concern. A professional contractor:

• Provides a detailed schedule showing which areas will be affected on which days
• Communicates directly with tenants (or coordinates through you) about access restrictions
• Performs noisy or disruptive work during off-hours when required
• Cleans up at the end of each workday
• Protects tenant signage, landscaping, and property from damage

What to expect: A specific plan for managing tenant impact, not just a general assurance that "we'll work around your tenants."
