Why we take on commercial work differently

Commercial interiors run on a different clock than residential renovations. Your business either stays open through construction or it opens on a scheduled launch date. The jobs that finish on time are the ones where the scope is fully written before demo starts.

A written scope, not a range

Every line item priced, every allowance defined, before demolition begins. Change orders happen in writing before the work does. You know the number you signed is the number you will pay.

One crew across the trades

Drywall, paint, and custom millwork are in-house. The same team hangs, tapes, paints, and installs the built-ins - fewer handoffs, no "who owns this?" gaps between subs.

Built for occupied buildings

Elevator bookings, after-hours access, hoarding, landlord site-manager coordination, and mall construction rules built into the schedule. Neighbouring suites stay operational through construction.

A firm schedule with weekly updates

Retail opening dates and office move-ins hold because the schedule was realistic to begin with. Weekly written progress against the plan, not a scramble in the final week.

What clients say

A. Victor

Awat and his team are THE BEST! They painted 8 townhomes for me and fully finished 2 large townhome basements with framing, drywall, flooring, plumbing, electrical and a 2-piece washroom. I highly recommend Adept for small and large jobs.

Commercial project types we take on

Every project gets a written scope with line-item pricing and a firm schedule before demolition begins. We are a good fit for small and mid-sized commercial interiors between 500 and 10,000 sq ft: professional offices, retail stores, clinics, studios, and mixed-use spaces.

Commercial project types and typical scope
Project typeTypical scope
Small tenant suite (up to 1,500 sq ft)Written scope · 3–6 weeks active build
Mid-size office fit-out (1,500–5,000 sq ft)Written scope · 6–10 weeks active build
Retail storefront or in-mall buildoutWritten scope · fixed opening date
Multi-office layout (5,000+ sq ft)Written scope · phased schedule
Tenant improvement (leasehold)Written scope · single change log for all parties

Timelines exclude pre-construction (materials, permit drawings, and building coordination), which happens before Week 1. Retail buildouts run to a fixed opening date; we schedule backwards from that date.

Trades that finish every commercial project

Interior demolition, metal-stud framing, drywall to Level 4 or Level 5 spec, commercial interior painting, doors and trim, custom built-ins and millwork, and punch-list touch-up - all under one accountable crew.

Factors that affect scope and price

  • Floorplate size and partition layout complexity
  • Base building condition and demising requirements
  • Finish package: drywall level, paint spec, millwork
  • Custom built-ins: reception, shelving, storage
  • Access windows and after-hours coordination
  • Fire-rated assemblies, occupancy classification changes
  • City of Toronto building permits when required

How long does a commercial fit-out take in Toronto?

A mid-size office fit-out typically runs 6 to 10 weeks of active build; small tenant suites often close in 3 to 6 weeks. Retail buildouts run to a fixed opening date. Pre-construction (materials, permit drawings, building coordination) happens before Week 1 - a typical mid-size fit-out looks like this:

  1. Weeks 1–2

    Pre-construction: written scope confirmed, materials ordered against known lead times, permit drawings received, building coordination scheduled (elevator bookings, after-hours access, hoarding). Nothing gets torn out before this closes.

  2. Weeks 3–4

    Demolition, metal-stud framing, drywall hanging. Dust containment kept tight so neighbouring suites stay operational. Loud work scheduled outside tenant hours where the building requires it.

  3. Weeks 5–6

    Taping and finishing to Level 4 or Level 5 spec, prime and paint, doors and trim, millwork install: reception, storage, display fixtures. Weekly written progress updates.

  4. Weeks 7–8

    Punch-list, deficiency correction, and pre-occupancy touch-up. Final walkthrough on the scheduled date. Warranty handoff in writing.

Long-lead millwork, occupancy-classification changes, and after-hours-only work windows can add 1–2 weeks. We build these into the schedule during pre-construction so the target opening date holds.

Working in occupied buildings and in-mall spaces

Most commercial work we take on happens in occupied buildings with tight access windows, elevator booking rules, and a landlord's site manager to coordinate with. Loud work (demolition, framing) is scheduled outside standard tenant hours where the building requires it.

For in-mall retail buildouts, we work within the mall's construction rules: after-hours work, hoarding, and coordination with the mall project office. Dust containment stays tight enough that neighbouring suites keep operating.

Commercial renovation permits in Toronto

Most commercial interior work in Toronto requires a building permit, particularly when the project changes the floor plan, alters occupancy classification, or affects fire-rated assemblies. The City of Toronto Building Division reviews and issues these permits, and the Ontario Building Code governs the technical requirements.

We do not file the permit application itself - that is your design team's role (architect, interior designer, or code consultant), and the city owns the review and issuance. What we do: scope the project so you know upfront which portions require a permit, coordinate with your architect or designer during design development, build to the approved drawings without field changes that would trigger a revision, and keep the site inspection-ready at every stage.

6 questions to ask before hiring a commercial contractor

Use this checklist on every quote call, including ours. For the full hiring playbook, see our guide on how to hire a renovation contractor in Toronto.

  • Is the full scope of work priced in writing before demo begins?
  • Are drywall, paint, and millwork in-house or subcontracted?
  • How are change orders documented, and who has to approve them?
  • What building coordination do you handle: elevator, after-hours, hoarding?
  • What is your dust containment plan for occupied buildings?
  • Which drywall finish level do you deliver, and is that in the quote?

Toronto commercial renovation FAQs

Do commercial renovations in Toronto require a building permit?
Most commercial interior work in Toronto requires a City of Toronto building permit, particularly when the project changes the floor plan, alters occupancy classification, or affects fire-rated assemblies. The City of Toronto Building Division reviews and issues the permit, and the Ontario Building Code governs the technical requirements. Filing the permit application is your design team's role (architect, interior designer, or code consultant). Adept scopes your project so you know upfront which portions require a permit, then builds to the approved drawings and keeps the site inspection-ready at every stage.
How long does a commercial fit-out take in the GTA?
A small tenant suite fit-out typically runs 3 to 6 weeks of active build after pre-construction closes. Mid-size offices between 1,500 and 5,000 sq ft run 6 to 10 weeks. Retail buildouts run to a fixed opening date; we schedule backwards from that date so it holds. Pre-construction (materials, permit review, building coordination) happens before Week 1, and its length depends on lead times and your design team's schedule.
Do you work in occupied buildings and in-mall spaces?
Yes. Most of the office work we take on happens in occupied buildings with tight access windows, elevator booking rules, and a landlord's site manager to coordinate with. For in-mall spaces, we work within the mall's construction rules: after-hours work, hoarding requirements, and coordination with the mall's project office. Loud work is scheduled outside tenant hours where the building requires it, and dust containment is kept tight enough that neighbouring suites stay operational.
What size of commercial project is a good fit for Adept?
We are a good fit for small and mid-sized commercial interiors between 500 and 10,000 sq ft: professional offices, retail stores, clinics, studios, and mixed-use spaces. Commercial projects at our size get one accountable point of contact, not a general contractor who subcontracts every trade and adds a management fee on top.
How do you handle change orders on commercial projects?
Every change order is documented and priced in writing before the work happens. For tenant improvement (TI) projects where landlord, tenant, and property manager all need to sign off, we keep a single change log that all three parties can reference, updated weekly. The base building work letter stays intact so nothing gets confused between the base scope and the change scope.
What drywall finish level do you deliver on commercial jobs?
Standard commercial spec is Level 4 for painted walls under standard lighting, and Level 5 for walls in critical lighting conditions or with gloss/semi-gloss finish. Both are included in our written scope up front - not treated as an upgrade after the fact. We build to the finish level specified in the design package.
Do you handle drywall, painting, and millwork with your own crew?
Yes. Drywall installation and finishing, commercial-grade interior painting, and custom built-in millwork are all handled in-house by the same team. That means handoffs are internal, the same crew that hangs the drywall paints it and installs the millwork, and one accountable point of contact runs the project from demolition to final walkthrough.
