Grant Deneau Tower receives historic register listing

A downtown Dayton office tower has been placed on the National Register of Historic Places.

The designation makes it eligible for historic tax credits that officials say are necessary to renovate the building into housing and office space.

The Grant Deneau Tower, 40 W. Fourth Street, was listed on the national register earlier this year — despite being less than 50 years old, which is generally required for inclusion on the list.

In December, the Ohio Historic Site Preservation Advisory Board officially endorsed designating the tower after agreeing it has exceptional historic importance.

The building’s ownership has proposed spending $35 million or more to renovate the 23-story building into market-rate housing on the upper floors and office space on the lower floors.
