SCHEDULING INSPECTIONS AND RESPONSE TIME

• Inspections must be requested at least 24 hours prior to the date the inspection is needed. To schedule an inspection, you must have the appropriate permit number(s) available when you call.
• To schedule fire protection or fire alarm inspections you must provide the street address, level or area, permit number, and type of inspection needed. Note that inspections on multiple floors in commercial buildings are considered separate inspections and must be scheduled as such. Each floor must be scheduled individually. In most cases, inspection requests made before 12 noon will be scheduled for the next business day. A specific time for an inspection cannot be given at the time that the inspection is scheduled.
• A re-inspection fee will be assessed for any system that has been disapproved twice. The fee amount assessed will be 50% of the original inspection fee.      
• If you have a job specific question during installation, please call the inspector assigned to the area in which the project is located. To find the name and contact information for the fire protection or fire alarm inspector, please click on the blue i button on the right hand side of the following web page: http://permittingservices.montgomerycountymd.gov/dpstmpl.asp?
• Inspections which cannot be performed because the inspector cannot gain access to the inspection site or where work is incomplete, will be considered disapproved, counting toward the two allowed disapprovals. To avoid re-inspection fees, inspections may be canceled by phone prior to the inspector’s arrival.
• Be certain that your inspection site is clearly marked with a lot number, suite number or address. If the lot is not marked, the inspection will be rejected.
