Commercial Renovation Contracts in Vancouver: Fixed Price, Cost Plus, Payments and Change Orders

A practical guide to reviewing scope, price structure, payment milestones, holdback, schedule and closeout before construction begins.

A commercial renovation contract should explain how the project will be run, not merely state a total price. Once demolition begins, most disagreements are not about whether the owner wanted a finished space. They are about whether a particular item was included, who carried an approval, what evidence supports an invoice, and whether a site change affected the opening date.

That makes contract review especially important for tenant improvements in Vancouver and the Lower Mainland. The work may involve the business owner, landlord, strata, consultants, municipal reviewers, base-building vendors, equipment suppliers and multiple trades. A short proposal can leave those interfaces unresolved even when both parties are acting in good faith.

The purpose of this guide is not to replace legal advice. It is to help business owners identify the commercial and construction details that should be settled before a deposit is paid or work is authorized.

• Choose the price model only after considering how complete the drawings are and how much concealed-condition risk remains.

• Treat drawings, specifications, exclusions, allowances, alternates and the landlord manual as part of the contract package, not background material.

• Tie progress payments to measurable work and supporting records rather than dates alone.

• Keep statutory holdback, deficiency money and disputed amounts separate in both the contract and invoice review.

• Require written change authorization that records scope, price and schedule impact before extra work proceeds, except under a defined emergency process.

A signed agreement cannot carry the whole project by itself. The contract should identify every document that defines the work and establish which document controls if two requirements conflict.

For a typical commercial interior renovation, the package may include architectural and engineering drawings, specifications or finish schedules, the contractor's scope and price breakdown, exclusions, allowances, accepted alternates, schedule, landlord construction rules, insurance requirements and supplementary conditions.

Record document titles, dates and revision numbers. 'As per drawings' is weak if the drawing set is not named, or if pricing was completed against an earlier issue. The same applies to an email promise that never appears in the signed scope.

If a document can change price, time or responsibility, identify it in the contract package. Before signing, compare the contract list against the documents the estimator actually used.

A Fixed Price or stipulated-price contract sets an agreed amount for a defined scope, subject to the contract's adjustment rules. It is most useful when drawings are coordinated, major selections are known, site information is reasonably reliable and bidders have priced the same responsibilities.

Fixed Price does not mean every future condition is included. Concealed damage, hazardous materials, utility conditions, landlord-directed work, design revisions or an owner-requested upgrade may sit outside the defined scope. The contract should explain how those conditions are notified, investigated and valued.

A Cost Plus contract reimburses defined project costs and adds an agreed contractor fee. It can fit fast-track work, early demolition, incomplete design or a project with substantial unknowns. The owner receives flexibility, but final cost certainty is lower unless the agreement includes reporting controls, a target budget or a guaranteed maximum price with carefully written assumptions.

Define reimbursable cost: trade invoices, labour rates, supervision, equipment, delivery, small tools, permits, insurance, travel and other categories should not be left to assumption.

State whether the contractor fee is a percentage or fixed amount, what the fee applies to, and whether trade markups are already included.

Set the required backup: invoices, time sheets, purchase orders, delivery records and a current cost report.

Identify which commitments require owner approval before purchase and how often the forecast-to-complete is updated.

A hybrid arrangement can be practical: a fixed price for well-documented work, unit rates for measurable unknown quantities, and allowances for products that are not yet selected. The categories must be separated clearly enough that the same cost is not recovered twice.

Price certainty comes from scope certainty and contract controls, not from the words 'Fixed Price' alone.

A contract total should reconcile with the accepted proposal. If the estimate changed during negotiation, compare the final scope line by line. Y&Y's article on why commercial renovation quotes differ explains how exclusions and assumptions can make similar totals cover different work.

Confirm whether the stated price includes applicable taxes and which party pays permit fees, consultant fees, testing, utility charges, landlord review costs, parking, after-hours premiums, disposal, final cleaning and equipment commissioning. The answer can vary by project; it should not vary between the estimate and contract.

Separate contractor work from owner-supplied and landlord-supplied work. For every excluded interface, name the party responsible for design information, purchase, delivery, installation, connection, inspection and warranty. An owner-supplied oven, for example, may still require electrical, gas, ventilation and millwork coordination by several parties.

An exclusion is not fully understood until the owner knows who will perform the work and when it must occur.

An allowance is a placeholder for work or material that cannot yet be priced precisely. It should state what it covers, the assumed quantity or quality level, whether labour, delivery and contractor fee are included, and how the final difference will be credited or charged.

Unit rates are useful when quantity is unknown but the work can be measured, such as an agreed rate per square foot, linear foot, fixture or labour hour. Define the measurement method, minimum charges and approval record. A unit rate without measured quantity is not a complete price control.

Alternates allow the owner to add or remove defined work. State the acceptance deadline because an alternate may affect procurement, permit drawings or the critical path. Once accepted, it should be incorporated into the current contract value and scope log.

Before signing, build a one-page list of every allowance, unit rate and alternate. That page often reveals where the budget remains exposed after the headline price has been agreed.

An allowance is a visible budget assumption, not a promise that the final selection will cost the same amount.

A commercial project may require a deposit for mobilization, submittals or long-lead procurement, followed by progress payments and a closeout payment. The exact percentages depend on the job. The more important question is what each payment represents.

Ask for a schedule of values that divides the contract into recognizable work packages. Each progress claim can then show the original value, previously billed amount, current progress, approved changes, holdback where applicable and remaining balance.

The invoice process should state the billing cut-off, review period, payment due date and required support. For stored or specially fabricated materials, confirm product identification, paid invoices where required, storage location, insurance, ownership and what happens if the design or permit changes.

Calendar-only milestones such as '30% on June 1' can disconnect payment from site reality. A better milestone describes a result, such as approved procurement, rough-in completion subject to inspection, millwork delivery, or substantial completion supported by a deficiency list.

Every invoice should let the owner answer three questions: what was completed, what changed, and what remains.

British Columbia's Builders Lien Act creates statutory holdback obligations for construction work. In general terms, the Act requires a 10% holdback and provides a 55-day holdback period calculated from the applicable completion, abandonment or termination event. The correct trigger and release process depend on the project structure and facts, so owners should obtain legal advice where needed.

Statutory holdback is not the same as money retained because a deficiency remains open, documentation is missing or an invoice is disputed. Combining all three under the word 'holdback' makes final-payment discussions harder and can lead to incorrect administration.

The contract should state who calculates holdback, what appears on each invoice, whether a certificate of completion will be used, what documents are required before release, and how lien searches or legal review will be handled where appropriate.

Name each withheld amount and its reason separately: statutory holdback, deficiency retention or disputed work.

Commercial renovation changes are normal. The control problem begins when the site proceeds on a sketch, text message or meeting comment without recording the commercial result.

A change order should carry a unique number, describe the reason and revised work, reference the current drawing or instruction, break down price and applicable tax or markup, state any schedule impact, and identify who authorized it. Credits deserve the same documentation as additions.

The contract should distinguish a quotation request from authorization to proceed. It should also identify approval limits: who can sign for the owner, whether email approval is accepted, and whether the project manager can authorize only up to a stated amount.

For urgent work needed to protect life, property or completed construction, define an emergency notice and documentation process. 'Emergency' should not become a standing substitute for written approval.

No change is fully approved until both its cost and schedule effect are recorded. A zero-dollar change can still delay an inspection or opening date.

A start date is credible only when its prerequisites are listed. Common prerequisites include executed contract, deposit, issued drawings, permits or authorization to proceed, landlord approval, site access, proof of insurance, equipment information and release of long-lead purchases.

Define the target for substantial completion and what remains afterward. Also record work hours, shutdown windows, elevator bookings, delivery routes, inspection responsibility and owner decision deadlines. In an occupied building, phasing and temporary access may be contract work rather than informal site coordination.

The delay clause should address owner changes, late information, concealed conditions, authority or landlord delays, unavailable products and other events relevant to the project. It should require prompt notice and an updated schedule rather than waiting until the original completion date has already passed.

The full sequence from lease review through handover is outlined in Y&Y's tenant improvement guide. The contract schedule should identify which party owns each step in that sequence.

A completion date without written start prerequisites and delay-notice rules is only a target.

Substantial completion, occupancy, business opening and total completion are not always the same date. The contract should define the milestone used for progress payment, holdback administration, warranty commencement and schedule reporting.

List the expected closeout package: approved inspection records, deficiency list and completion evidence, warranties, operating and maintenance information, keys and access credentials, equipment training, testing or balancing reports, and as-built information where required by the contract or authorities.

Confirm warranty duration, response procedure, exclusions and responsibility for manufacturer warranties. A warranty promise is more useful when the owner knows where to submit a request, what information to include and how urgent service is handled.

Termination, suspension and dispute clauses also deserve attention before a problem exists. Review notice periods, payment for work completed, treatment of ordered materials, access to drawings and records, and the steps required before litigation or arbitration. Legal review is sensible when the contract value, operating risk or proposed terms justify it.

Closeout is a defined deliverable, not the point when the site becomes quiet.

Place the final agreement, proposal, drawing list and schedule side by side. Confirm the following before signatures and deposit:

• Contracting company and authorized signatories match the proposal, insurance and payment instructions

• Drawings, specifications and revisions are listed by date

• Fixed Price, Cost Plus, allowances, unit rates and alternates are labelled consistently

• Taxes, permit costs, consultant fees and owner-supplied items are assigned

• Deposit and progress payments correspond to defined work or procurement

• Holdback, deficiencies and disputed amounts have separate treatment

• Change approval records both price and schedule impact

• Start prerequisites, completion milestone and delay notices are defined

• Warranty and closeout documents are listed

• Every verbal commitment that affected the decision appears in the written package

Owners still comparing teams can use Y&Y's seven contractor checks before signing before moving into this final contract review.

Y&Y Construction approaches commercial renovation as a coordinated path from design and approvals through construction and handover. Contract discussions are tied back to the current drawings, operating requirements, landlord conditions, procurement plan, known site risks and opening target.

The goal is not to pretend that every condition can be known before demolition. It is to make the known scope clear, give each remaining unknown a control method, and keep decisions traceable as the project changes.

Ask for a written procurement authorization identifying the exact product, supplier quote, deposit amount, cancellation or restocking terms, expected delivery, storage location, insurance and ownership. Confirm whether the permit or final design could change the item, who carries that risk, and how the payment will appear in the schedule of values. An early purchase can protect the schedule, but it should not be an unexplained lump-sum deposit.

Not automatically. Review the defined scope, existing-condition information, exclusions and concealed-condition clause. The contractor should document the condition, explain why the existing contract does or does not cover it, and issue a priced change with schedule impact before corrective work proceeds, unless immediate action is required for safety or property protection under the contract's emergency process.

Use the contract's definitions and payment conditions rather than appearance alone. Reconcile completed work, outstanding deficiencies, inspection status, closeout documents, approved changes and statutory holdback treatment. Record each unpaid amount and its reason separately. If the contractual or lien implications are unclear, obtain project-specific legal advice before withholding or releasing funds.
