Police will move in with Bassetlaw District Council later this year as part of a restructure in Worksop amid Government cuts.
The move will see officers relocate from Potter Street to share Queen's Buildings with the authority.
The announcement comes after months of negotiations.
Chief Constable Craig Guildford said: "Sharing facilities with Bassetlaw District Council means that Nottinghamshire Police will have less square feet, but more on the beat. That’s what I want and that's what the public want. We are not just maintaining our local policing presence but increasing it.
"We now have an additional dedicated police officer for Worksop town centre who has been in post since January and three new PCSOs. A new CID unit will also move in once works have been completed too, followed by a new schools liaison officer in September.
"I would like to thank local politicians and in particular councillor Simon Greaves, John Mann MP and Police and Crime Commissioner (PCC) Paddy Tipping whose collective challenge and support has assisted myself and the local authority chief executive to deliver a great outcome for the good people of Bassetlaw."
Coun Greaves, leader of the council, said: "We are delighted to be working closer with Nottinghamshire Police and, as part of this relocation, have been able to secure the appointment of additional officers who are already walking the streets of Worksop, as well allowing a number of other positions to be brought back to the town.
"This is an extremely positive move for both the police and Bassetlaw District Council and will further enhance the services we are able to offer Bassetlaw residents in Queen's Buildings as part of our one-stop service that currently includes the Department for Work and Pensions, Citizens Advice and 2 Shires Credit Union."
PCC Mr Tipping said: "All public services will continue to face significant financial challenges in the future and working more closely with our partners, like this, is a logical step that delivers economic savings while providing better facilities for the public.
"It's police officers and staff who keep our communities safe, not buildings. By working with our local authority partners, we are creating an efficient, fit for purpose and sustainable estate that helps to improve services and deliver value for money across the board."
A Nottinghamshire Police spokesman added: "The relocation is in response to the Government's reductions in police funding, which has hit Nottinghamshire particularly hard with £56million of cuts completed to date and a further £12m required to meet their target.
"Work on the dedicated offices at Queen's Buildings is expected to start imminently with Nottinghamshire Police planning to move into its new Worksop home later this year."
