Renovation, Tenant Improvements and Occupied Buildings

Chicago Renovation Defect Expert

Paul Gaston is a Chicago renovation defect expert for remodels, gut rehabs, tenant improvements and work in occupied buildings. Since 2007 he has directed renovation at O'Hare International Airport, a facility that never closes, and he evaluates whether defects resulted from the new work, existing conditions, phasing and protection, or later use.

Renovation Is Most of Chicago's Construction

In a city with Chicago's building stock, much construction is renovation: kitchen and bath remodels, gut rehabs of two-flats and greystones, conversions of older commercial buildings, tenant improvements in office towers and retail corridors, and renovation of institutional and public buildings. Renovation disputes have their own character because new work meets old work, and the line between them is where many problems appear.

New Work, Existing Conditions and the Connection

When a renovation shows defects, there are usually three candidates: the new work itself, the existing building, and the connection between the two. A new hardwood floor that cups may reflect installation, moisture from an old basement or slab, or a failure to account for an uneven subfloor. Paul evaluates all three, using the scope documents to determine what the contractor was responsible for addressing and the field conditions to determine where the problem originated.

Tenant Improvements

Chicago tenant improvement work involves landlords, tenants and contractors, with lease work letters defining responsibilities and building standards defining materials and details. Paul evaluates the installed work against the construction documents, approved submittals and building standards, and identifies the party that performed the disputed work. Allocation under the lease is left to counsel.

Work in Occupied Buildings

Renovation in occupied buildings requires phasing, protection of occupants and existing finishes, controlled access and often night work. Defects in this setting may result from the installation, from inadequate protection, or from operations after turnover. Paul has managed this kind of work at O'Hare for nearly two decades and previously supervised renovation of City of Chicago facilities, including public safety buildings, for the Department of General Services. He evaluates whether the contractor planned and protected the work as the conditions required.

Rehabilitation Code Context

Renovation of previously occupied Chicago buildings may be permitted under the Chicago Building Rehabilitation Code (Title 14R) rather than the Building Code for new construction. That affects which requirements apply to the altered areas. Paul reviews the permit to determine the compliance path before addressing any code question within his experience. See Chicago construction code compliance and Chicago repair cost evaluation.

Documenting Before the Next Phase

In phased renovation, the next phase often covers the evidence of the last. Paul can document conditions before follow-on work proceeds, so that disputes about earlier phases can be resolved on a record rather than on memory.

Questions

Common Questions

How does Paul tell whether a renovation defect came from the new work or the old building?

He evaluates the new work, the existing conditions and the connection between them, using the scope documents to determine what the contractor was responsible for addressing.

Does Paul handle tenant improvement disputes in Chicago?

Yes. He evaluates the installed work against the documents and building standards and identifies the performing party; lease allocation is for counsel.

Why is occupied-building renovation different?

Phasing, protection, access and night work create additional risks. Defects may result from protection failures or later operations, not only installation.

Which Chicago code applies to a renovation?

It depends on the permit. Many renovations of previously occupied buildings use the Building Rehabilitation Code, Title 14R.

A Chicago construction dispute that turns on the work?

Send the party names for a conflict check. Paul knows how work is permitted, built and inspected in Chicago.
