Landlord Work Letter in a Commercial Lease

A landlord work letter in a commercial lease is the exhibit or schedule that specifies which improvements the landlord will design, build, and deliver at or before occupancy, and which the tenant must fund or build itself. The work letter translates the lease negotiation into concrete construction and cost responsibilities, establishing the baseline condition of the space, any allowances the landlord provides, and the standard for “completion.”

Why Work Letters Matter

A commercial lease is partly about rent and term, but much of the deal value sits in the landlord’s pre-opening contribution. In an office tower, retail center, or industrial park, the space starts as an empty shell. Someone must:

• Design the layout and mechanical systems
• Install walls, flooring, lighting, and HVAC
• Connect utilities and telecommunications
• Comply with building codes and permits
• Coordinate construction timing and approvals

A work letter allocates these costs and responsibilities. Without one, disputes flare up: the landlord claims the tenant must fund its own build-out; the tenant believes the landlord promised to deliver a “fully improved” space. The work letter prevents that chaos and protects both parties’ financial assumptions.

Core Components of a Work Letter

1. Base Build and Landlord Scope

The “base build” defines what the landlord will deliver. Examples:

• Structural shell (roof, exterior walls, columns)
• Common areas (lobbies, hallways, restrooms, mechanical rooms)
• Standard mechanical, electrical, plumbing (MEP) risers and distribution
• Backup power for common areas
• Fire life-safety systems (sprinklers, alarms, exits)
• Parking (if included in the lease)

A turnkey work letter obligates the landlord to deliver an “move-in ready” space with finished flooring, painted walls, ceiling, light fixtures, and HVAC tuned to the tenant’s specifications. A shell or base-building work letter delivers only structure and core systems; the tenant finishes the interior.

2. Tenant Improvement (TI) Allowance

The landlord often offers a dollar allowance (e.g., $40 per rentable square foot) toward tenant-funded improvements. The tenant chooses how to spend it:

• Partition walls
• Premium flooring or branding finishes
• Conference rooms or specialty spaces
• Custom lighting or acoustic treatments
• Upgraded HVAC zoning or controls

If the tenant’s build-out costs exceed the allowance, the tenant pays the overage (called “TI overage” or a cost-sharing arrangement). If the tenant spends less, the landlord typically keeps the difference, though some leases offer the tenant a credit toward rent.

3. Design and Construction Standards

The work letter specifies:

• Which architect and contractor design and build (landlord-selected, or landlord approval of tenant-selected)
• Construction documents and permits required before work begins
• Building code and ADA compliance obligations
• Material and finishes standards (e.g., “commercial-grade finishes only”)
• Warranty periods for landlord’s work (typically 1 year)

4. Timeline and Conditions Precedent

The work letter locks in:

• When the landlord will begin design and construction
• How long construction is expected to take (construction period)
• The “substantial completion” date and move-in readiness standard
• Conditions the tenant must meet before landlord starts (e.g., tenant approval of plans, proof of financing for overage costs)

Delays are often addressed with “abatement”—rent reduction for each month the space is not ready on schedule, incentivizing the landlord to finish on time.

5. Change Orders and Cost Control

Once work starts, changes to the scope drive cost overruns. The work letter typically requires:

• Written change orders approved by both parties before additional work proceeds
• Clear mechanics for who pays for changes (usually the tenant)
• Disputes resolved through a general contractor or third-party arbiter if costs or scope conflict

Turnkey vs. Allowance Structures

Turnkey Structure

The landlord designs and delivers a finished, fully compliant space. The lease specifies the exact uses (e.g., medical office with exam rooms, specific lab equipment). The landlord absorbs cost overruns up to a cap. The tenant reimburses the landlord for costs above the cap. Turnkey is simpler for the tenant but gives the landlord less certainty on total investment.

Allowance Structure

The landlord gives the tenant a fixed dollar allowance and the tenant (or its architect/contractor) designs and builds. The tenant pays overages dollar-for-dollar. This caps the landlord’s cost exposure and gives the tenant flexibility. The trade-off: the tenant bears more construction risk and complexity.

Hybrid

Many leases combine both: the landlord delivers a base build (shell, MEP, code compliance) and provides an allowance for tenant-funded finishes.

Landlord’s Indemnity and Tenant’s Obligations

The work letter typically includes:

• Landlord indemnity: The landlord warrants that its work complies with codes, is free of defects, and is completed in a professional manner. If something fails during the warranty period, the landlord repairs it at no cost to the tenant.

• Tenant indemnity: The tenant (or tenant-hired contractors) indemnifies the landlord for negligence, accidents, or code violations during tenant-funded work. The tenant also indemnifies the landlord against claims from its own build-out.

• Insurance and bonding: Large-dollar work letters often require the general contractor to carry performance bonds (guaranteeing completion) and payment bonds (guaranteeing workers and suppliers are paid).

Substantial Completion and Punchlist

“Substantial completion” occurs when the space is ready for the tenant’s occupancy and use, even if minor items (light fixture installation, paint touch-ups) remain. The work letter defines substantial completion and establishes a “punchlist”—a line-item checklist of remaining work. The landlord must complete punchlist items within 30–60 days of occupancy; if major items remain, the landlord is typically in default and the tenant can abate rent.

Payment Mechanics

Most work letters require the landlord to fund its work during construction, whether by:

• Direct construction contracts and payment
• Reimbursement to the tenant if the tenant hires the contractor
• A construction loan that funds progress payments (the tenant then pays off the loan from the TI allowance)

For tenant-paid portions (overage, design fees, optional upgrades), the tenant usually pays the contractor or reimburses the landlord after invoices and architect certification of completion.

Tax and Accounting Treatment

For the landlord, the cost to deliver the work letter is typically capitalized as part of the leasehold improvement asset and depreciated over the lease term or the improvement’s useful life (usually 15 years). The landlord deducts depreciation as an operating expense.

For the tenant, improvements funded from the landlord’s allowance are often capitalized by the tenant (at fair value equal to the allowance) and depreciated. Tenant-funded overages are also capitalized and depreciated.

Common Disputes and Protections

Scope Creep

The tenant requests “just one more” partition or HVAC tweak; costs balloon. Prevention: a fixed allowance with transparent overage rates and a sign-off threshold (e.g., changes over $5,000 require both parties’ approval).

Contractor Performance

The landlord’s contractor delays or produces poor work. The work letter should specify remedies: penalty clauses, third-party inspection, and the tenant’s right to abate rent for unresolved major defects.

Code Compliance

The landlord’s work letter includes responsibility for building code compliance, but changes to building codes mid-project can increase costs. The work letter should clarify: does the landlord pay for code upgrades triggered by new code changes, or does the tenant?

Latent Defects

After move-in, the tenant discovers water damage or HVAC malfunction. The work letter warranty period (often 1 year) should apply, and the landlord should be obligated to remediate.

Real-World Example

An office tenant leases 10,000 square feet at $30/SF annually ($300,000/year). The landlord offers $25/SF TI allowance ($250,000). The lease calls for:

• Landlord delivers: shell, core MEP, code compliance, standard flooring, painted walls, lighting
• Landlord’s cost: $240,000 (in line with the $25 allowance)
• Tenant’s needs: upgraded finishes, interior glass walls, premium lighting, custom furniture system
• Tenant’s build-out cost: $320,000
• Overage: $320,000 – $250,000 = $70,000 (tenant pays this directly to contractor)
• Total build-out cost: $240,000 (landlord) + $320,000 (tenant) = $560,000

The work letter specifies the tenant’s $70,000 overage is the tenant’s sole obligation; the landlord funds and manages the $240,000 base build. If the tenant’s architect finds the space needs additional structural work costing $15,000, the tenant pays this cost via a change order.
