Julia Mulligan, who is standing for re-election this year, has announced her decision following a examination of the services offered at local stations.
Ms Mulligan claims that only one in 20 crimes are now reported by people coming into a police station.
Under the new hours Scarborough’s station, in Northway, will close its doors two hours earlier each night at 10pm.
Ms Mulligan said: “[i have agreed to] amend the opening hours of existing police station front counters to better reflect the actual usage of the communities they support, and using those hours to provide necessary secretarial and exhibits (i.e. storage) support.
“In addition, we have listened to the public’s feedback that they find it extremely frustrating to see people in a police station but for them not to answer the door.
“A new policy of ‘when we’re in, we’re open’ will be introduced.
“This means that even if front counter staff are not working, but others are, the public will still get a response and the station will be open to them.”
The move is currently projected to save £300,000 in its first year, and £330,000 in each subsequent year.
The savings will be invested in more police officers and PCSOs.
