The location is between the Grocery Outlet & Dollar General on Olive Avenue at Mains Street.
It comes two years after the original library burned to the ground and claimed the lives of two firefighters.
A new permanent library is scheduled to be completed in 2024.
Porterville officials say the new state-of-the-art library will offer many more services thanks to the community's input.
The new building will also be a tribute to Porterville Fire Captain Raymond Figueroa and firefighter Patrick Jones who gave their lives fighting the flames.
