Landlord Work & Base
Building Services in the
Greater Toronto Area
Property owners and managers across the GTA trust Silcon Construction to maintain, repair, and upgrade the base building systems and common areas that keep commercial properties operational, compliant, and competitive. From central HVAC and main electrical distribution to lobby improvements, parking structures, and life safety systems — we deliver landlord work with the coordination, documentation, and compliance standards that commercial property management demands.
What Is Landlord Work in Commercial Construction?

Clear Definition
Landlord work refers to the construction, maintenance, and upgrade of the base building components that fall under the property owner's responsibility, as distinct from the tenant improvement work that individual tenants fund and control. Base building systems include central mechanical and electrical infrastructure, the building envelope, common areas, life safety systems, and the structural and compliance elements that serve the entire property rather than any single tenancy.

Why It Matters
The condition of a landlord's base building directly affects the property's value, the quality of the tenancies it can attract, the rent it can command, and its ongoing compliance with Ontario's building, fire, and accessibility codes. Deferred landlord work compounds — a neglected facade leads to water infiltration, a failing HVAC system drives tenant disputes, and an accessibility gap becomes a regulatory liability. Proactive, well-executed landlord work protects the asset and the income it generates.

The Silcon Approach
We act as a general contractor and project manager for landlord work across various commercial property types in the GTA—retail, office, mixed-use, and industrial. We coordinate trades, liaise with property management and engineers, and deliver base building work to meet asset and tenant standards. For seasonal tasks like envelope repairs and waterproofing, we plan around Ontario's climate to protect buildings before winter and restore them afterward.

Landlord Work & Base Building Services We Deliver
Base Building Systems
The mechanical and electrical infrastructure that serves the entire property is maintained and upgraded at the landlord level to ensure reliable service for all tenancies.
Central HVAC systems
inspection, servicing, repair, and replacement of central plant equipment, including chillers, boilers, cooling towers, air handling units, and rooftop package units; ductwork modifications to accommodate new or changing tenancy configurations; coordination with mechanical engineers where system redesign is required
Main electrical distribution
work on main switchgear, distribution panels, transformer equipment, and building-wide electrical infrastructure; capacity upgrades to support increased tenant electrical loads; coordination with the utility and the Electrical Safety Authority for work on regulated systems
Water supply & main plumbing lines
inspection, repair, and replacement of domestic water supply mains, sanitary and storm drain systems, backflow prevention devices, and building-wide plumbing infrastructure serving multiple tenancies; coordination with the municipality for any work affecting the building's connection to the municipal water and sewer systems
Building Envelope
Exterior systems protecting the building are maintained on a schedule addressing Ontario's seasons. Envelope work is urgent due to damage from water infiltration, freeze-thaw, and storms, worsening over time. Spring and early summer are ideal for inspections, sealant replacement, waterproofing, and cladding repairs — after winter's damage and before the next season.
Exterior facade maintenance
inspection and repair of exterior cladding systems, including EIFS, masonry, metal panel, glass curtain wall, and mixed-material facades; sealant and caulking replacement at joints, penetrations, and window perimeters; brick and block repair; surface cleaning and treatment programs; remediation of spalling, cracking, or delaminating cladding elements before they become safety hazards or allow water infiltration
Waterproofing & leak remediation
application and replacement of waterproofing membranes at roofs, podium decks, planters, and below-grade walls; roof leak investigation and repair; caulking and sealant programs at envelope penetrations and transitions; remediation of water infiltration damage to building structure and interior systems
Window systems (base building)
inspection, repair, and replacement of base building window units and curtain wall glazing assemblies; weatherstripping and seal replacement; remediation of failed IGU units and condensation issues; full window system replacement programs for buildings with aging or non-performing fenestration
Structural slab repairs
assessment and remediation of concrete slab defects in parking structures, podium decks, and elevated slabs; crack injection, surface repairs, concrete restoration, and expansion joint replacement; coordination with structural engineers for scopes requiring engineering sign-off before remediation proceeds
Common Areas
The shared spaces that shape the first impression of the property and directly affect the experience of every tenant and visitor in the building are maintained and improved as a landlord capital investment.
Elevator maintenance & modernization
coordination of elevator maintenance programs and cab improvement scopes; cab interior refreshes, including wall panels, flooring, lighting, and door surrounds; coordination with licensed elevator contractors for mechanical and code-related work; management of elevator modernization projects where existing equipment requires updating to current safety standards
Lobby & common corridors
maintenance, refresh, and renovation of building lobbies, elevator lobbies, common corridors, and shared tenant amenity areas; flooring replacement, wall finish updates, lighting upgrades, signage and wayfinding improvements, and millwork built-ins; scope managed as a capital improvement program with phased execution in occupied buildings
Parking structures
surface repairs, line repainting, lighting upgrades, and drainage maintenance for surface and structured parking areas; concrete repair and waterproofing programs for underground and above-grade parkade structures; bollard installation and replacement; EV charging station infrastructure installation as part of parking upgrade programs; coordination of parking control equipment installation and replacement where required
Life Safety Systems
The base building fire protection and emergency power systems that protect occupants and satisfy Ontario Fire Code and Ontario Building Code requirements at the landlord level.
Fire protection systems (base building)
inspection, testing, repair, and upgrade of base building fire suppression systems, including sprinkler mains, riser systems, fire pumps, and suppression infrastructure serving multiple tenancies; coordination with licensed fire protection contractors and the local fire authority for systems requiring third-party inspection and approval; documentation of all testing and remediation to Ontario Fire Code standards
Emergency generators
inspection, load testing, fuel system maintenance, and repair of building emergency generators providing backup power to life safety systems, exit lighting, elevators, and other critical loads; coordination of transfer switch testing and exercising on the schedule required by the manufacturer and the Ontario Electrical Safety Code; upgrade and replacement of aging generator equipment where existing capacity no longer meets the building's life safety load requirements
Building Safety & Compliance
The regulatory and accessibility requirements that apply to the building as a whole are assessed, remediated, and documented at the landlord level to protect the property from enforcement action and liability.
Accessibility upgrades (AODA and OBC)
assessment of the building's current accessibility conditions against the Accessibility for Ontarians with Disabilities Act requirements and the Ontario Building Code accessibility provisions; remediation scopes covering entrance configurations, accessible route continuity, washroom accessibility, elevator access, signage, and parking — designed and executed to bring the property into compliance with applicable standards and timelines
Base building code compliance
review of the building against current Ontario Building Code and Ontario Fire Code requirements; identification of non-conforming conditions resulting from code changes since original construction, tenant modifications, or deferred maintenance; remediation scopes permitted and executed to bring the building into compliance with documentation provided for municipal, insurer, and property management records
Planning Landlord Work Around the Ontario Climate Calendar
Building envelope and exterior landlord scopes have a seasonal dimension that interior and systems work does not. Ontario winters accelerate deterioration — freeze-thaw cycling opens cracks in masonry and concrete, ice damming stresses roof membranes, and salt exposure corrodes exposed metal elements. The window between spring thaw and the onset of summer heat is the most productive period for envelope assessment, waterproofing, facade repair, and exterior restoration work.
Planning landlord envelope work in late winter — scoping, permitting, and procuring materials before the spring window opens — ensures the building is restored at the right time rather than rushed into a summer backlog or deferred another year.
For property managers building a landlord work calendar, we recommend aligning the envelope and exterior scopes with a spring mobilization, base building systems work with the fall shoulder season before heating demand increases, and compliance and interior common area scopes whenever lease events and tenant schedules allow.
How We Deliver Landlord Work
Property Assessment & Condition Review
We begin with a thorough walkthrough of the property — base building systems, envelope conditions, common areas, life safety infrastructure, and any known compliance gaps. We document existing conditions, identify deferred items, and establish a clear picture of the building’s current state before defining any scope. For multi-building portfolios, we conduct assessments across all properties and consolidate findings into a unified condition report.
Scope Definition & Prioritization
Based on the assessment, we work with you to define and prioritize the landlord work program — separating urgent remediation from planned capital upgrades, and phasing the work around your budget cycle, lease events, seasonal windows, and tenant operational requirements. You receive a clear written scope and schedule before any work is committed.
Permit Coordination & Engineering Alignment
Landlord work frequently requires building permits, engineering sign-off, and coordination with the local fire authority, the utility, or the Electrical Safety Authority. We manage the permit submissions, coordinate with your engineers and consultants, and ensure the required approvals are in place before any regulated work begins. Nothing proceeds without the right documentation.
Managed Construction & Trade Coordination
We act as the general contractor for the full scope — holding the trade contracts, sequencing the work, managing site safety, and enforcing the schedule. For landlord work in occupied buildings, we plan the construction sequence to protect tenant operations, minimize disruption to common areas, and comply with any building access restrictions.
Inspection, Documentation & Handover
We coordinate all required inspections — municipal building inspections, fire authority sign-offs, ESA certificates of inspection, and any third-party commissioning required for mechanical or life safety systems. You receive a complete project close-out package including permit sign-offs, inspection records, compliance documentation, and as-built information for the building file.
Why Property Owners and Managers Choose
Silcon for Landlord Work in the GTA

We Understand the Landlord-Tenant Dynamic
Landlord work takes place in buildings where tenants are operating, leases are in effect, and disruption has real financial consequences. We plan base-building scopes around lease events, coordinate access with tenant operations teams, and execute the work with the level of professionalism required for a managed commercial property. We've worked in some of the GTA's most demanding commercial environments — the protocols aren't new to us.

Compliance Documentation That Holds Up
Ontario Building Code permits, Fire Code sign-offs, ESA certificates, AODA remediation records — landlord work generates compliance documentation that needs to be accurate, complete, and properly filed. We manage the permit and inspection process, coordinate with the authorities, and deliver a close-out package that provides your property management team and legal advisors with what they need.

One Point of Contact for Multi-Trade Scopes
Landlord work routinely involves structural, mechanical, electrical, fire protection, and civil trades, all working on the same property. Rather than managing four separate subcontractors through four separate contracts, you engage Silcon as your general contractor, and we own the coordination. One scope. One schedule. One accountable contact from assessment to handover.

From Landlord Work to Tenant Improvement
Property owners who use Silcon for landlord work frequently engage us for the tenant improvement scopes that follow — new tenancy buildouts, suite renovations, and fitout coordination. We already know the building, its systems, and its quirks. That continuity makes the TI scope faster, more accurate, and less disruptive than starting fresh with a new contractor.

A Track Record in High-Profile GTA Properties
We've delivered construction and renovation work at Upper Canada Mall, Hillcrest Mall, Scarborough Town Centre, Yorkdale Shopping Centre, and Maplelands on Bloor Street — environments with rigorous contractor vetting, strict site protocols, and zero tolerance for work that doesn't meet the property management standard. That experience translates directly to how we approach landlord work at every commercial property we serve.
Compliance & Safety First
Landlord work in Ontario is heavily regulated — building permits, fire authority approvals, ESA inspections, and AODA compliance requirements all apply depending on the scope of work. We operate with documented safety programs and hold current registrations with ISNetworld and Avetta, satisfying the contractor pre-qualification requirements that most commercial property managers impose before granting site access.




Landlord Work Works Best Alongside
Landlord work doesn’t exist in isolation — it connects upward to capital programs and downward to ongoing operations. The services our landlord clients most frequently draw on:

General Contracting
When landlord work transitions into a full construction scope — new demising walls, suite rebuilds, or base building upgrades that require a permitted general contract — we deliver it through the same team already engaged on the property

Project Management
For multi-phase landlord programs spanning several buildings, fiscal years, or concurrent tenant events, we provide full project management oversight from planning through to close-out

Contractor
The hands-on trade execution behind every landlord scope we take on — structural, mechanical, electrical, and finishing work delivered by a commercial contractor that meets the vetting requirements of managed commercial properties

Building Maintenance
Once base building systems are upgraded or replaced through a landlord work program, ongoing scheduled maintenance keeps them performing between capital cycles

Seasonal Services
Exterior restoration, waterproofing, facade repairs, and site-level work planned around the Ontario climate calendar — the seasonal complement to your year-round landlord work program

Site Work
Exterior and ground-level construction scopes that run alongside base building programs — parking structure repairs, drainage, paving, bollard installation, EV charging infrastructure, and site restoration

Industries
Landlord work sets the stage for the tenant improvement scopes that follow. Explore the industry-specific renovation services we deliver for office, retail, restaurant, industrial, and washroom fitouts across the GTA

Retail Construction
When a landlord is preparing a space for an incoming retail tenant, the brand-specific construction scopes follow immediately: storefront glazing systems, specialty lighting, POS infrastructure, and visual merchandising integration delivered by the same team already engaged on the property

Frequently Asked Questions
What is the difference between landlord work and tenant improvement work?
Landlord work involves the base building systems and common areas managed by the property owner, including mechanical, electrical, the building envelope, lobbies, parking, and safety systems. Tenant improvement work focuses on the interior fitout of tenant spaces, usually funded and controlled by tenants. Often, both run simultaneously — landlord systems need to be in good condition before tenant improvements can begin, and new tenancies may prompt landlord upgrades during lease negotiations. We handle both and know how they interact.
Do you work directly with property management teams and building engineers?
Yes — this is how most landlord work engagements are structured. We interface with your property management team for access coordination, tenant communication, and scope approvals, and with your building engineers and consultants for permit drawings, structural sign-offs, and mechanical and electrical design. We’re comfortable operating within a managed property environment where multiple stakeholders are involved in every decision.
Can you manage landlord work in occupied commercial buildings without disrupting tenants?
Yes. The majority of our landlord work is conducted in occupied properties. We plan construction sequences around tenant operating hours, schedule disruptive work within approved windows, and communicate proactively with property management and tenants about access requirements and anticipated impacts. Occupied building construction is a discipline we’ve developed across years of work in active retail centres, office towers, and mixed-use properties.
What permits and approvals are typically required for landlord work?
It depends on the scope. Structural repairs, envelope modifications, base-building mechanical and electrical work, and life-safety system upgrades typically require Ontario Building Code permits and, depending on the system, coordination with the Electrical Safety Authority, the local fire authority, or a licensed specialty contractor. We manage the permit and approval process as part of the project scope — you don’t have to navigate those relationships yourself.
How do you handle AODA accessibility compliance for commercial properties?
We begin by assessing the property’s current accessibility conditions against AODA and the Ontario Building Code requirements, identifying the gaps, and developing a remediation scope that addresses them in priority order. Common scopes include entrance reconfiguration, accessible washroom retrofits, elevator access improvements, and parking modifications. All work is documented for your AODA compliance records and coordinated with the applicable permits.
When is the best time of year to plan building envelope and exterior landlord work?
Spring — specifically the window between the end of freeze-thaw cycling and the onset of summer heat — is the optimal period for facade inspections, sealant and caulking replacement, waterproofing programs, and exterior concrete and masonry remediation. We recommend scoping and permitting envelope work in late winter so mobilization can happen as soon as conditions allow. Waiting until the deficiency is visible from the inside usually means the water damage has already begun.
Do you work on parking structures and exterior building elements?
Yes. Parking structure maintenance and repair — concrete remediation, waterproof membrane application, drainage, line repainting, bollard installation, and EV charging infrastructure — is part of our landlord work offering. Exterior facade work, including sealant replacement, cladding repairs, and window system upgrades, is also within our scope. For work requiring engineering sign-off, we coordinate with your structural or building envelope engineer throughout the project.
Can Silcon manage a multi-building landlord work program across a portfolio?
Yes. For property owners and managers overseeing multiple commercial properties, we can conduct assessments across the portfolio, consolidate findings into a unified condition report, and develop a phased capital program that prioritizes the most critical scopes first. Having one contractor managing the program across multiple buildings improves consistency, simplifies reporting, and gives you a single point of accountability across the portfolio.
How does Silcon coordinate landlord work with tenant improvement scopes happening at the same time?
Carefully. When landlord base building work and tenant fitout work are running in parallel — as they often do during a new tenancy buildout — we establish clear sequencing between the two scopes, define the interfaces between base building systems and tenant rough-ins, and coordinate access so neither scope delays the other. If we’re managing both the landlord work and the TI scope, that coordination is entirely internal. If a separate TI contractor is involved, we establish the coordination protocols at the start of the project.
