A practical verification guide for business owners comparing contractors for a tenant improvement, retail, office, restaurant or service-space renovation.
A useful contractor portfolio should show completed commercial spaces where layout, millwork, lighting and day-to-day operations were coordinated as one project.
Choosing a commercial renovation contractor is not a portfolio contest. A polished finished space matters, but it does not show who held the contract, whether the same project manager is still with the company, how the estimate was written, or what happened when site conditions changed.
The decision is harder in a leased commercial unit because the contractor works inside several systems at once: the owner's budget and opening date, the landlord's construction rules, municipal permits and inspections, base-building services, neighbouring tenants and the operating needs of the business. A team can be good at construction and still be a poor fit if it cannot manage those interfaces.
The safest selection process is document-based. Ask every serious bidder for the same information, check the information against the proposed scope, and record the answer before comparing price. The seven checks below are designed for that purpose.
Key takeaways
• Confirm the legal company that will sign the contract and the business-licence requirements that apply to the project location.
• Request a current WorkSafeBC clearance letter, not only an account number or verbal assurance.
• Review the insurance certificate for the correct company name, policy dates, limits and project or landlord requirements.
• Test experience against the actual business type, building systems and approval path, then confirm who will manage your project.
• Compare estimate scope, exclusions, allowances, schedule assumptions and change-order rules before comparing totals.
Before interviewing contractors, issue the same project brief
Contractor comparison becomes unreliable when each company is pricing a different project. Before requesting proposals, prepare a short brief with the site address, lease or landlord manual, available drawings, intended use, major equipment, desired opening date, known work-hour restrictions and any areas that must remain operational.
State what is still unknown. If the permit drawings are incomplete, equipment has not been selected or the landlord has not reviewed the concept, say so. A responsible contractor can then identify assumptions rather than hiding them inside a lump-sum number.
The first test is whether the contractor asks useful questions before giving a confident price. Questions about electrical capacity, HVAC, washrooms, fire protection, loading, waste, equipment and landlord approvals usually indicate that the team is trying to understand the real scope.
1. Verify the legal business and who will sign the contract
Ask for the exact legal name, operating name, business address and the name that will appear on the contract, invoices, insurance certificate and WorkSafeBC documents. These names should make sense together. If a portfolio belongs to one company but the contract is issued by another, ask for the relationship in writing.
Business-licence requirements can depend on the municipality and how the contractor operates there. Do not stop at the phrase 'we are licensed.' Ask which business licence applies to the project location, whether it is current, and which permits or trade qualifications are carried by subcontractors rather than the general contractor.
A company name that changes between the proposal, insurance and payment instructions is a reason to pause. It may have a reasonable explanation, but the owner should understand who is legally responsible before paying a deposit.
2. Obtain a WorkSafeBC clearance letter for your contract
A WorkSafeBC account number is not the same as evidence that an account is active and in good standing. Ask for a clearance letter addressed to the hiring company or owner for the contractor that will perform the work.
WorkSafeBC explains that a hiring business may be liable for premiums connected with work performed by a registered contractor that has not made required payments. Its official guidance recommends obtaining a clearance letter before and after services. The letter should cover the period of the contract, so treat it as a project document rather than a one-time screenshot.
Check clearance before mobilization and again before final payment. Also ask how the general contractor verifies the trade contractors it hires. The goal is to understand the coverage chain, not merely collect one PDF.
3. Read the commercial liability insurance certificate
Request a current certificate of insurance from the insurer or broker where practical. Confirm the named insured matches the contracting company, the policy is active through the expected work period, and the coverage addresses commercial construction operations.
The required limit is not universal. A landlord, strata, property manager or contract may require a particular commercial general liability limit, additional insured wording, automobile coverage or other project-specific terms. Send those requirements to the bidder before contract execution and ask who will provide the final certificate.
Insurance does not replace a clear scope or competent site management. It is a financial protection layer. If the contractor will not provide a certificate until after a deposit, clarify the sequence in writing before signing.
4. Match experience to the real project, then verify the proposed team
Ask for two or three completed projects that resemble the current job in the ways that create risk. For a restaurant, that may be kitchen equipment, ventilation, grease, gas, health review and shutdown coordination. For an office, it may be data, occupied floors, acoustic work and phased moves. Retail and service spaces may depend on storefront rules, secure inventory, customer access, privacy or after-hours work.
Do not accept a gallery as the complete answer. Ask what the contractor's scope included, which municipality and landlord were involved, what changed after demolition, how long the work took and whether the person presenting the project actually worked on it.
Who will be on this project?
Request the proposed project manager and site superintendent, not only the salesperson or company owner. Ask how many other active projects they will carry, how often the project manager will visit, who can approve a site decision and who sends the weekly update.
Company experience and project-team experience are not automatically the same. A strong portfolio is relevant only if the contractor can connect it to the people, systems and subcontractors proposed for this job.

5. Compare the estimate by scope, not by the bottom line
Use the same drawings and project brief for all bidders, then compare scope categories. Y&Y's guide to why commercial renovation quotes differ explains how exclusions, allowances, unknown site conditions, after-hours work and permit responsibilities can create large differences between totals.
For this selection stage, check whether the proposal identifies demolition, temporary protection, framing, ceilings, doors, millwork, finishes, mechanical, electrical, plumbing, fire protection, equipment connections, permits, inspections, cleaning and closeout. The exact categories depend on the project, but a single unexplained construction number is difficult to evaluate.
Mark every allowance and owner-supplied item. Ask what quantity, product level or labour assumption supports it. Also identify work by landlord vendors, base-building contractors or specialist suppliers. Those interfaces often become schedule gaps if no one is named as coordinator.
A low bid is not comparable until its exclusions and allowances are placed beside the other proposals. The objective is not to eliminate every unknown; it is to make the remaining unknowns visible before contract signing.

6. Test the project-management and communication system
Ask the contractor to show the actual format it uses for a construction schedule, request for information, submittal log, change order, site report and deficiency list. Blank templates are acceptable. The point is to see whether the process exists before the project becomes busy.
Confirm who coordinates landlord submissions, elevator bookings, shutdown notices, deliveries, inspections and trade access. For occupied or shared buildings, ask how high-impact work is communicated to the owner and neighbouring tenants.
The contractor should also explain how the job moves from design and approvals into construction and handover. The broader tenant improvement process is useful context because many delays occur between parties rather than within one trade.
A weekly meeting is not a communication system unless decisions, owners and due dates are recorded. Ask where the current drawing, schedule and approved change information will live, and how the owner will know which version controls.

7. Confirm the contract controls before paying a deposit
Before signing, confirm the contract identifies the drawings and scope documents, price basis, taxes, payment milestones, holdback treatment where applicable, start assumptions, substantial-completion target, change-order authorization, insurance, warranty and closeout requirements. Obtain legal advice where the risk or contract value warrants it.
The payment schedule should follow understandable progress, not only calendar dates. Ask what evidence supports each invoice and what happens when work is incomplete, disputed or waiting for inspection. No extra work should rely solely on a verbal conversation if it changes price or time.
List the required handover documents: inspection records, operating manuals, warranties, keys, access credentials, training, as-built information where required and a deficiency process. The next article in this series will examine contract types, payment milestones and change orders in more detail.
Do not let an urgent opening date turn unanswered contract questions into site problems. A few extra days spent aligning documents can prevent weeks of dispute after demolition starts.

Call references with project-specific questions
Ask for references from recent commercial work, preferably with a similar scope or building condition. Confirm permission to contact them and ask questions that require more than a yes-or-no answer:
• What was included in the original contract, and what changed?
• Who managed the project day to day, and how quickly were decisions documented?
• Were invoices and change orders understandable before work proceeded?
• What caused the largest delay, and how did the contractor respond?
• Was the deficiency and handover process completed as expected?
References are most useful when the same names, project facts and constraints appear consistently across the proposal, portfolio and conversation.

Use a simple contractor comparison scorecard
Score each bidder on the same categories: credentials and documents, relevant experience, proposed team, estimate completeness, schedule logic, communication system, references and contract clarity. Record evidence beside the score.
Do not assign most of the weight to presentation quality. A polished interview can hide an incomplete scope, while a technically strong contractor may communicate more plainly. Weight the categories according to project risk: a commercial kitchen may place more weight on mechanical coordination; an occupied clinic may prioritize phasing, dust control and privacy.
The selected contractor should be the team with the clearest, most credible plan for the actual project, not simply the lowest total or largest portfolio.
Warning signs before contract signing
Treat these as reasons for further verification, not automatic proof of a problem:
• The legal company name is unclear or changes across documents
• WorkSafeBC clearance or insurance is repeatedly deferred
• The estimate is a single number with few assumptions or exclusions
• Similar projects cannot be connected to a recent client reference
• The proposed project manager or superintendent is not identified
• Permit, landlord and inspection responsibilities are described as 'handled' without an owner
• Extra work can proceed without written price or schedule approval
• The requested deposit is not connected to a clear contract and mobilization plan
How Y&Y approaches contractor selection questions
Y&Y Construction reviews commercial renovation as a combined design, approval, construction and handover process. Early discussions focus on the business model, lease and landlord constraints, building systems, permit path, budget assumptions, procurement and opening target.
Owners considering a project can review Y&Y's commercial design and renovation services and bring the address, available drawings, landlord criteria, equipment information and desired schedule to an initial conversation.
The goal of contractor selection is not to remove all uncertainty. It is to choose a team that identifies uncertainty early, assigns responsibility and documents decisions before they affect the site.
Frequently asked questions
The proposal, insurance certificate and payment instructions show different company names. What should I do?
Pause before paying a deposit. Ask for a written explanation of the legal relationship, identify the entity that will sign the contract and perform the work, and confirm that the insurance certificate and WorkSafeBC clearance apply to that entity and the contract period. Different names may have a legitimate explanation, but responsibility and coverage should be clear in writing first.
The contractor is on the landlord's approved contractor list. Do I still need to complete my own checks?
Yes. Landlord approval may address building access, insurance thresholds, work rules or familiarity with the property. It does not necessarily mean the landlord has reviewed your scope, estimate, project team, schedule, change-order process, references or construction quality. Treat landlord approval as one project requirement, not a substitute for owner due diligence.
Which documents should be confirmed before paying a construction deposit?
At minimum, confirm the contracting entity, signed contract, current drawings and scope, exclusions, allowances, payment milestones, start assumptions, written change-order process, current insurance certificate and WorkSafeBC clearance. Also identify the project manager and site contact, plus any landlord or permit conditions that must be satisfied before mobilization. The deposit amount and timing should be connected to a clear contractual purpose.
