Workflow

Overview

Drafting tenant improvement work letters requires careful attention to construction timelines, cost allocation, and allowance disbursement terms. Attorneys spend hours customizing templates, ensuring consistency with the base lease, and negotiating provisions for hard costs, soft costs, permits, and excess expenses. Manual drafting increases the risk of missing critical provisions or creating inconsistencies between the work letter and lease agreement.

Attorneys spend hours crafting detailed provisions for design approval, TI allowances, disbursement procedures, and completion timelines. Manual drafting is time-consuming, prone to inconsistencies, and often delays lease execution.

Questions

What is a tenant improvement work letter?

A tenant improvement work letter is a detailed exhibit to a commercial lease that governs the construction, approval, and payment process for improvements to leased premises. It establishes procedures for design approval, construction standards, tenant improvement allowances, disbursement of funds, and completion timelines. The work letter protects both landlord and tenant by clearly defining responsibilities, costs, and procedures throughout the improvement process.

What costs are typically covered by a tenant improvement allowance?

Tenant improvement allowances typically cover hard costs (direct construction costs including labor and materials) and soft costs (architectural fees, engineering fees, permits, and project management). The work letter should specify which costs are eligible for reimbursement and which are excluded, such as furniture, equipment, telecommunications cabling, or costs from tenant-requested changes. Any costs exceeding the allowance are the tenant's responsibility.

How long does the tenant improvement approval process take?

The approval timeline varies but typically includes 10-15 business days for landlord review of each plan submission, plus time for tenant to prepare initial designs and incorporate revisions. The complete process from initial space plan through final approved construction documents often takes 4-8 weeks. The work letter should establish specific deadlines for each phase and address whether approval delays extend the rent commencement date.

What happens if tenant improvements aren't completed on time?

The work letter should distinguish between excusable delays (force majeure, landlord-caused delays, governmental delays) and non-excusable delays (tenant-caused delays, contractor issues). Excusable delays typically extend the rent commencement date, while non-excusable delays do not. The work letter may also establish landlord's remedies for failure to complete, including the right to complete the work and charge the tenant or terminate the lease.

Can CaseMark customize the work letter for different types of commercial properties?

Yes, CaseMark generates work letters tailored to your specific lease terms and property type, whether office, retail, industrial, or mixed-use. The AI adapts provisions for design approval processes, construction standards, allowance structures, and completion requirements based on your transaction details. You can customize TI allowance amounts, eligible costs, approval timelines, and other key terms to match your deal structure.
