When reviewing a commercial lease, one of the most important distinctions to understand is who is responsible for construction and build-out costs. This responsibility is typically divided between landlord work and tenant improvements, but the difference is not always obvious.
What Is Landlord Work?
Landlord work refers to construction, repairs, or improvements that the property owner is responsible for completing, typically to deliver the space in a leasable condition.
Typical Characteristics of Landlord Work
- Performed before or early in the lease term
- Focused on making the space functional and compliant
- Benefits the property long-term, not a specific tenant’s operations
Common Examples
- Structural elements (walls, floors, roof)
- Base building systems (HVAC, electrical capacity, plumbing mains)
- Fire and life safety systems
- Code compliance upgrades
- Common area improvements
- Delivering a “shell” or “vanilla shell” condition
Landlord work is usually standardized and applies across multiple tenants, especially in multi-tenant buildings.
What Are Tenant Improvements (TI)?
Tenant improvements are modifications made specifically for a tenant’s use of the space. These changes reflect how the tenant plans to operate their business.
Typical Characteristics of Tenant Improvements
- Customized to tenant needs
- Often negotiated as part of the lease
- May be funded by the tenant, the landlord, or both
Common Examples
- Interior walls and partitions
- Flooring, ceilings, and finishes
- Lighting layout changes
- Plumbing for restrooms, kitchens, or specialty uses
- Branding and interior design elements
- Office layouts or retail build-outs
Tenant improvements are often tied to a Tenant Improvement Allowance (TIA), which defines how much the landlord will contribute toward these costs.
What is the difference between landlord work and tenant improvement?
| Category | Landlord Work | Tenant Improvement |
| Responsible Party | Landlord | Tenant (often with landlord contribution) |
| Purpose | Make space leasable | Customize space for tenant use |
| Scope | Base building and core systems | Interior layout and finishes |
| Timing | Before or early in lease | Usually after lease execution |
| Customization Level | Low | High |
| Cost Responsibility | Landlord | Tenant or shared |
| Ownership After Lease | Landlord | Often reverts to landlord |
| Accounting Treatment | Capital improvement | Leasehold improvement |
This distinction is central to lease negotiations and budgeting decisions.
Financial Responsibilities and Cost Implications
Who Pays for Landlord Work?
Landlord work is generally funded entirely by the property owner, as it improves the long-term value of the building.
Who Pays for Tenant Improvements?
Tenant improvements are typically handled in one of three ways:
- Tenant-funded – Tenant pays all costs
- Landlord-funded allowance – Landlord provides a TI allowance
- Turnkey build-out – Landlord completes all work to an agreed standard
If improvement costs exceed the allowance, the tenant usually pays the difference.
Lease Structure and Contractual Language
The lease is the final authority on what qualifies as landlord work versus tenant improvement.
Key Lease Components
- Work Letter – Details construction responsibilities
- Scope of Work – Defines what is included or excluded
- TI Allowance Clause – Sets funding limits and reimbursement rules
- Turnkey Provisions – Shift construction responsibility to landlord
Ambiguous language in these sections is a common source of disputes.
Overlap and Gray Areas
In practice, the line between landlord work and tenant improvements is not always clear.
Common Gray Areas
- Electrical capacity upgrades
- HVAC modifications for tenant equipment
- Restroom additions or relocations
- ADA upgrades triggered by tenant changes
In competitive markets, landlords may absorb more of this work to attract tenants.
Real-World Use Cases
Retail Tenants
Retail tenants often require extensive tenant improvements, including branding, displays, and customer-facing layouts.
Office Tenants
Office spaces may rely more on landlord work initially, with tenant improvements focused on layout and finishes.
New Construction vs Existing Buildings
- New builds: More landlord work upfront
- Existing spaces: Higher tenant improvement costs for customization
