The Building Operator's Guide to Tenant Improvements

As a building manager or operator, you oversee commercial properties where a tenant improvement (TI) request triggers a different set of questions depending on who receives it:

• Tenants are confirming the scope covers their layout and electrical requirements
• Leasing teams are calculating TI allowance cost per square foot against term length
• Property managers are coordinating permit timelines and vendor access during the build-out
• Finance teams are working out how the allowance amortizes into the lease economics
• Asset managers are evaluating how the improvement affects long-term asset value

Commercial tenant improvements, also called leasehold improvements, are interior modifications that directly affect whether a tenant renews. JLL found that re-letting a commercial space costs more than twice what retaining a tenant requires and can reach the full value of an annual net rent. Most property owners underestimate the total because vacancy and refurbishment are visible, but leasing commissions and the full marketing period rarely make it into the calculation.

Given the high cost of losing tenants and Visitt's mission to deliver the kind of building operations that keep them, this practical guide covers every stage of the process, from how the TI agreement gets structured to what tenant experience looks like once the space is occupied. 

When it comes to tenant improvements, what falls on whom?

Lease negotiations determine which of the following TI structures apply:

1. TI allowance (TIA): The most common structure. The landlord provides a fixed per-square-foot budget, and the tenant manages construction against it, absorbing any overruns. Before vendor selection begins, define exactly what the allowance covers in writing.
2. Landlord build-out: In this model, your team manages construction and delivers the space to spec. The most common source of disputes is a design that was not documented in enough detail before tenant improvement construction started, so it’s important to get everything outlined in writing before breaking ground.
3. Tenant-managed build-out: The tenant runs the project independently, which means your team's role shifts to coordinating vendor access and ensuring compliance, which makes defining the review and sign-off workflow ahead of time a must.
4. Turnkey: Your team delivers a finished space, according to a tenant-approved design. Budget control and timeline accountability sit entirely with you from the first day of construction.

In a soft market where vacancy is high, tenants have more leverage to push for a higher allowance or a full landlord build-out. When vacancy tightens, landlords offer less, and tenant-managed models become more common.

Note that regardless of which model the build-out runs through, tenants improvements and betterments stay with the property at lease end. That has direct implications for how your team approaches capital expenditure planning and how insurance coverage gets structured at renewal.

Before construction starts: plan the right build-out

Needs assessment

• Document the tenant's layout requirements and equipment specifications 
• Inspect the existing space in person; what looks serviceable on a floor plan frequently needs upgrading once walls are opened, particularly HVAC systems and electrical panels in older buildings
• Verify the space's electrical capacity against the tenant's equipment load requirements; upgrading service panels mid-build is one of the most disruptive and expensive changes to absorb

Budget

• Define exactly what the TIA covers before vendor bids are collected
• Require proof of insurance and current contractor licensing before any vendor is engaged; this is as much a cost protection measure as a compliance requirement
• Set aside a 10 to 15 percent contingency; hidden conditions in existing infrastructure are common and rarely inexpensive

Design

• Require fully approved drawings before submitting for permits; changes after submission restart the review process
• Run an ADA compliance check at the design stage, covering door widths, restroom clearances, and accessible route requirements
• Confirm the design reflects the tenant's full operational requirements before drawings are finalized

Permits

• Identify permit timelines before confirming an occupancy date
• Assign one person to manage permit follow-up; processing delays are the most common source of schedule slippage in commercial tenant improvements

Contractor selection

• Require proof of current licensing and insurance before any vendor is engaged
• Walk the space with the contractor before finalizing the budget
• Get written scope sign-off from the tenant before the contractor is confirmed

Timeline

• Build material lead times for specialty items into the schedule before construction begins; custom millwork and specialized equipment can run 6 to 12 weeks out
• If the tenant is already occupying part of the space, phased construction allows work orders and tenant operations to continue without interruption while the build-out progresses

Managing the build-out: vendors, timelines, and tenant communication

Running a tight tenant improvement build-out comes down to a consistent set of practices your team controls directly. Your ability to see all building operations through a single operations dashboard during the construction phase can help you implement and enforce the following best practices:

After handover: ensure tenant improvements lead to tenant satisfaction

Certificate of occupancy and closeout

• Confirm all inspections have closed before issuing an occupancy date; outstanding items give tenants grounds to delay rent commencement
• Deliver a complete closeout package at handover: as-built drawings, equipment warranties, operation and maintenance manuals, and a subcontractor list for future service needs

Post-occupancy communication

• Schedule a 30-day check-in after move-in to review and resolve any remaining issues 
• Give tenants a direct channel for submitting maintenance requests from day one; a tenant app connected to your work order system removes the friction that turns minor issues into formal complaints

Keep your tenant improvements and tenant relationships connected 

Visitt connects the operational work of a tenant improvement project to the tenant relationship that follows it. During the build-out, vendor documentation and certificates of insurance stay organized in one platform without switching between systems.

Once a tenant takes occupancy, maintenance management workflows route requests from newly installed systems to the right team member with full asset context, and the tenant app keeps communication direct from move-in through renewal. Every example of a leasehold improvement your team delivers connects to the workflows that protect tenant satisfaction and long-term occupancy.
