Before you hire
Tenant Improvement in Metro Detroit: what to expect
Tenant improvement (TI) work adapts a leased commercial space for a specific tenant: new walls and offices, updated restrooms, lighting, flooring, paint, data cabling and mechanical changes. It ranges from a light refresh between tenants to a full reconfiguration.
The lease drives the project. It says who pays for what (often through a TI allowance), who hires the contractor, what landlord approvals are needed, and when rent starts. Reading the work letter before getting bids avoids surprises.
TI work falls under the Michigan Building Code. Even smaller changes can trigger plan review for exits, accessibility, fire separation and occupancy. Working in an occupied building also means after-hours work, protecting common areas, and coordinating with building management. In older Detroit office and retail buildings, existing conditions such as outdated wiring, limited restroom counts or missing fire protection can expand the scope once walls are opened.
What a proper job includes
- Review of the lease work letter and landlord rules
- Drawings from design professionals where required
- Plan review and building permit
- Licensed electrical, plumbing, mechanical and fire protection trades
- Protection of common areas and neighboring tenants
- A schedule tied to lease milestones
- Final inspections, closeout documents and lien waivers
What drives the price
- Scope: cosmetic refresh versus full reconfiguration
- Restroom and accessibility upgrades
- Mechanical and electrical changes
- Fire alarm or sprinkler modifications
- Landlord requirements for contractors and insurance
- After-hours or phased work in occupied buildings

Permits and licensing in Michigan
Tenant improvements are permitted under the Michigan Building Code, often with plan review before work starts. In Detroit, permits and inspections go through BSEED; elsewhere, the city or township building department (or the county or state, where they enforce) issues them.
LARA licenses residential builders, not commercial builders, so ask about commercial experience and insurance. Licensed electrical, plumbing and mechanical contractors pull their own permits. Collect sworn statements and lien waivers with each payment.

Common questions
Tenant Improvement FAQ
Money the landlord provides toward improvements, set in the lease. The lease says how it is paid and what it covers.
Either, depending on the lease. The landlord usually approves the contractor and plans.
Most does, beyond paint and carpet. Changes to walls, exits, restrooms and systems need permits.
The terms overlap. Build out often means finishing a shell; TI usually means modifying an existing space for a tenant.
It depends on scope and plan review. A light refresh may take a few weeks, while a full reconfiguration with permits and inspections can take a few months, so build review time into your lease dates.
