New Berlin Fire Department crews were called in to back up Brookfield firefighters at a reported structure fire at 375 S. Moorland Road on July 13, 2026, according to a social-media update from the department. In a post timestamped 02:44:33 UTC, officials said New Berlin units were operating as part of a mutual-aid response. Authorities had not released any information about possible injuries or the cause of the blaze at the time of the post.
Mutual aid under MABAS Division 106
The New Berlin update noted that the call was handled under MABAS Division 106, the mutual-aid box alarm system used across Waukesha County when local departments need extra apparatus or manpower. Per Waukesha County Communications, Division 106 dispatches predetermined resources - engines, ladders and support crews - using pre scripted box cards for working structure fires. The setup is designed so neighboring departments can move quickly when a single department's resources are stretched thin.
What we know about the scene
According to a Facebook post by the New Berlin Fire Department, crews were on scene at 375 S. Moorland Road assisting Brookfield units. The address corresponds to the Sheraton Milwaukee Brookfield Hotel and adjacent commercial parcels, per the hotel's official listing, though officials have not said which specific building was affected. As of the initial update, Brookfield and New Berlin authorities had not released information on injuries, evacuations or road closures tied to the fire.
Neighborhood context and past mutual aid calls
New Berlin crews helped Brookfield at other structure fires earlier this year. As outlined by the City of New Berlin, the New Berlin Fire Department is a full-time department that regularly staffs mutual-aid responses for larger incidents. Those cooperative runs are coordinated through Division 106 so departments can tap the right combination of engines, ladders and support teams without losing time.
Where to get updates
Officials urged residents to steer clear of the immediate area and to rely on official channels for information as the response continues.

This story will be updated as Brookfield and other agencies release additional details.
