A plan is underway for the $25 million sale and upgrade of the Patten Towers at 11th and Market.

The matter is set to go before the city's Health, Education and Housing Facility Board on April 25.

The board will be asked to issue bonds for the purchaser, ECG Patten Towers LP.

The former Patten Hotel has long served as a low-income, senior facility. Under the new owner, it would still be for low-income and moderate-income housing.

It is one of the top sites in the city for police and fire calls.

The once-popular hotel is in the Innovative District the city is promoting to spur technology firms to grow and expand in Chattanooga.
