The city received permission this week from county officials to use Hall B in Plummer Park for city offices for two more weeks. The city, which has been unable to find new offices, was supposed to leave the park by Wednesday.
Members of a city hall search committee said they have run out of leads in their quest for 10,000 square feet of office space.
Supervisor Ed Edelman warned the city in a letter that state park regulations "preclude indefinite use of park space for offices." Continued use of the building as an office could lead the state to claim the land or withdraw park maintenance funds, according to John Stodder, a spokesman in Edelman's office.
If the city has not left its Plummer Park offices by May 15, the county may turn the park title over to the city, Stodder said. If the city wants to continue to rent the space from the county, the rent could be greatly increased from the current $1,000 a month.
