Commercial Lease Buildout Negotiation: TI Allowance, Work Letters, and Building Standards

Negotiating tenant improvement terms is one of the most important—and often misunderstood—parts of a commercial lease. The difference between a well-negotiated and poorly-negotiated TI package can be tens of thousands of dollars. This guide covers how to negotiate TI allowances, understand work letters, navigate building standards, and protect your interests in Washington State commercial leases.

Understanding TI Allowance Basics

A Tenant Improvement (TI) Allowance is money the landlord contributes toward building out your space. It's not free money—you're paying for it through your rent over the lease term.

How TI Allowances Work

Conceptually: The landlord fronts capital for construction. You repay it through higher rent over your lease term. The landlord spreads their cost over the lease and profits from the interest spread.

Example:

• $50/SF TI allowance on 5,000 SF = $250,000
• Landlord amortizes over 10-year lease at their cost of capital
• Adds approximately $2-3/SF/year to your base rent

Typical TI Allowances (Washington 2024)

Building Class	Office (per SF)	Retail (per SF)
Class A	$60-100	$30-50
Class B	$30-60	$15-35
Class C	$15-30	$5-20
Industrial	$5-15	N/A

Factors affecting TI allowance:

• Lease term length (longer = higher allowance)
• Credit quality of tenant
• Market conditions (landlord vs. tenant market)
• Space condition (shell vs. second-generation)
• Landlord's cost of capital
• Competing offers

Negotiating TI Allowance

Know Your Leverage

Tenant leverage is strongest when:

• High vacancy in the market or building
• You're a credit tenant with a strong balance sheet
• You're willing to sign a longer lease
• You have competing options
• The space has been vacant for extended periods

Landlord leverage is strongest when:

• Low vacancy market
• Space is highly desirable
• You need the specific location
• Short lease term requested
• Weak credit or startup business

Negotiation Strategies

Get real estimates first: Before negotiating, have an architect and contractor provide preliminary estimates for your buildout. You need to know what you actually need.

Don't accept the first offer: TI allowances are negotiable. The initial offer is usually 20-40% below what the landlord will ultimately accept.

Use competing offers: If you're considering multiple spaces, let landlords know. Competition increases allowances.

Trade lease term for TI: Longer lease commitments justify additional TI. Each added year typically means $5-10/SF more.

Understand landlord economics: Landlords prefer TI over rent reduction—TI is a one-time cost that adds building value, while rent reduction compounds over the term.

Ask for "as-is" credit: If you're taking space in good condition and need less work, negotiate a portion of standard TI allowance as rent credit or cash.

What TI Allowance Covers

Typically included (hard costs):

• Demolition of existing improvements
• Framing and drywall
• Ceilings and flooring
• Doors and hardware
• Millwork and casework
• Electrical and lighting
• HVAC modifications
• Plumbing modifications
• Fire and life safety
• Painting and finishes

Often excluded (soft costs):

• Architectural and engineering fees
• Permit fees
• Project management
• Furniture, fixtures, equipment (FF&E)
• Technology/IT infrastructure
• Moving costs
• Signage

Negotiate to include soft costs: Push to have 10-15% of TI allowance available for soft costs. "Hard costs only" provisions limit your flexibility.

The Work Letter

The work letter (or construction exhibit) is the section of your lease that governs tenant improvements. It's as important as the rent economics—maybe more so.

Key Work Letter Provisions

Base Building Condition

What the landlord provides before your buildout:

• Shell condition: concrete floor, bare walls, base building systems stubbed
• White box: drywall, ceilings, basic HVAC, lighting
• Warm shell: finished but generic, ready for minor customization

Negotiate clearly: Ambiguous base building conditions lead to disputes about what's included. Get specifics in writing.

Example language to seek: "Landlord shall deliver Premises with ceiling grid and tiles installed, HVAC system fully operational with distribution to Premises, electrical service with dedicated panel of not less than 200 amps, fire sprinkler heads installed to initial shell layout, and drywall ready for paint."

Building Standards

What it means: Landlords specify approved materials, systems, and finishes that are "building standard."

Why it matters: Building standard items are typically included in TI allowance at no markup. Above-standard items cost extra.

What to negotiate:

• Comprehensive building standards list before signing lease
• Above-standard items at cost (no markup)
• Flexibility to upgrade at tenant's cost
• Specific inclusion of items important to your build

Common building standards:

• Drywall: 5/8" Type X (fire-rated)
• Ceiling: 2x4 acoustic tile, suspended grid
• Flooring: Commercial-grade carpet tile or LVT
• Doors: Solid core wood or hollow metal
• Hardware: Building-standard lever sets
• Lighting: 2x4 LED troffers
• HVAC: Ceiling diffusers, standard zones
• Paint: Two coats, eggshell finish

Design and Approval Process

Typical process:

1. Tenant submits schematic design
2. Landlord reviews and comments (within X days)
3. Tenant submits design development drawings
4. Landlord reviews and comments
5. Tenant submits construction documents
6. Landlord approves for bidding and construction

What to negotiate:

• Approval timelines: Landlord must respond within 5-10 business days. No "deemed approved" for tenant submissions—get explicit approval.
• Approval standards: "Not to be unreasonably withheld or delayed." Without this, landlord has veto power.
• Dispute resolution: What happens if landlord and tenant disagree on design?

Contractor Selection

Landlord requirements may include:

• Approved contractor list
• Single pre-approved contractor (often unfavorable)
• Minimum insurance requirements
• Union labor requirements
• Background checks and security clearances

What to negotiate:

• Right to use any licensed, insured contractor
• At minimum, competitive bidding from multiple approved contractors
• Transparency on landlord markups for landlord-performed work
• Clear insurance and bonding requirements (so you can quote accurately)

Construction Management

Who manages construction?

• Tenant-managed: Tenant controls construction, typically with landlord oversight
• Landlord-managed: Landlord controls construction, bills tenant for overages

Tenant-managed advantages:

• Direct control over contractor
• No landlord markups
• Faster decision-making
• Accountability to you, not landlord

Landlord-managed considerations:

• May be required by some landlords
• Typical 3-10% management fee
• Less direct control but less administrative burden

Disbursement of TI Allowance

Methods:

• Reimbursement: Tenant pays contractor, submits invoices, landlord reimburses
• Direct payment: Landlord pays contractor directly
• Construction draw: Landlord pays monthly based on work completed

What to negotiate:

• Prompt reimbursement (within 15-30 days)
• Reimbursement as work progresses (not all at completion)
• Required documentation (lien waivers, permit sign-offs)
• Soft cost inclusion

Change Orders

How changes during construction are handled:

• Who approves changes?
• What's the markup on change order work?
• Does landlord approval slow the process?

Seek: Pre-approved change order threshold (e.g., tenant can approve changes under $5,000 without landlord consent)

Excess Costs

When your buildout exceeds TI allowance:

• How are overages paid? (Upfront vs. added to rent)
• What's the markup on overages if landlord pays?
• Who is responsible for cost verification?

Negotiate: Right to pay overages directly, rather than through landlord financing at unfavorable rates.

Protecting Your Interests

Before Signing the Lease

Get estimates: Don't sign based on assumptions. Get real construction estimates from architects and contractors.

Understand total costs: TI allowance + your cash = buildout budget. Know both numbers.

Review building standards: Obtain the actual standards before committing to ensure they meet your needs.

Verify base building condition: Physically inspect the space. What you're told may differ from reality.

Negotiate the work letter carefully: This isn't boilerplate. Every provision affects your buildout.

During Construction

Document everything: Photos, emails, change orders—all in writing.

Monitor the budget: Track spending against TI allowance weekly.

Get lien waivers: Collect partial and final lien waivers from all contractors and suppliers.

After Completion

Obtain closeout documents: As-built drawings, warranties, lien releases, Certificate of Occupancy, TI allowance reconciliation.

Punch list everything: Complete walk-through before final payments.

Common Pitfalls to Avoid

• Signing before estimates: TI allowances can't be renegotiated after signing. Know your costs first.
• Ignoring soft costs: "Hard costs only" means $15-25/SF out of pocket for design and permits.
• Accepting vague base building conditions: "Shell condition" means different things. Get specifics.
• Agreeing to landlord's contractor only: Single-contractor arrangements often mean above-market pricing.
• Overlooking approval timelines: Without deadlines, landlord approvals delay indefinitely.
• Not reading building standards: Above-standard finishes add cost not covered by allowance.

Questions to Ask

About TI Allowance

1. What is the TI allowance, and how is it calculated?
2. What costs are included in the TI allowance?
3. Can soft costs be included?
4. How is the allowance disbursed?
5. What happens if there's an overage?
6. Is any unused allowance available as rent credit?

About Building Standards

7. Can I get the full building standards specification?
8. What's the cost for above-standard upgrades?
9. Are there any restrictions on modifications?
10. What's the HVAC capacity in my space?

About the Work Letter

11. What is the base building condition at delivery?
12. What's the landlord approval process and timeline?
13. Can I use my own contractor?
14. What are insurance and bonding requirements?
15. Are there construction rules or restrictions?

Red Flags

• Extremely vague work letter: More ambiguity means more disputes
• Mandatory landlord contractor with no competitive bid: Above-market pricing
• TI allowance "subject to landlord approval of scope": Landlord veto over your buildout
• No approval timeline obligations: Delays cost rent without occupancy
• "Hard costs only" with no exceptions: You pay all soft costs out of pocket
• Building standards not provided until after signing: Committing blind
• No "reasonable consent" language: Landlord has absolute veto

Washington-Specific Considerations

• Contractor licensing: All contractors must be registered with L&I. Verify at verify.lni.wa.gov.
• Permit timeline: 4-12 weeks for commercial permits. Seattle is often longest.
• Energy code: WSEC affects HVAC and lighting. Budget for compliance.
• Seismic requirements: May be required depending on location and scope.
• Prevailing wage: May apply if landlord receives public funding.

Timeline Considerations

Phase	Duration
Initial lease negotiation	2-8 weeks
Work letter negotiation	1-4 weeks
Design development	4-8 weeks
Landlord approvals	2-4 weeks
Permitting	4-12 weeks
Construction	8-16 weeks

Start early: Work backward from your target move-in date. Commercial lease negotiations are complex, but the work letter and TI provisions deserve as much attention as the rent. Done right, a well-negotiated buildout package saves significant money and prevents headaches throughout your tenancy.
