By Computer: ePlats Online Functions

The Automated Inspection Request/Information System (AIRIS) allows callers to use a touch-tone telephone to schedule inspections.

When you are ready to schedule an inspection, please call (301) 883-5390.

  1. Call the AIRIS line at (301) 883-5390 between 7:00 a.m. and 11:00 p.m.
  2. Enter 1 to schedule an inspection.
  3. Enter telephone number with the area code followed by the # sign. For example, 3017568888#. This telephone number can be used by the inspector to contact the responsible party the day of the inspection if additional information is needed or questions arise.
  4. Enter your Case Number (this represents your permit sequence number) followed by the second group of numbers from your Case Number (this represents the year of your permit) followed by the # sign.
    • For example, if your permit Case Number is 12345-2004-00-C you would enter 123452004#. (12345 for the permit sequence number and 2004 for the four digits of the year 2004) DO NOT ENTER THE LAST GROUP OF NUMBERS. THEY REPRESENT REVISIONS TO THE PERMIT.
  5. Enter the 3 digit Inspection Request Code followed by the # sign.
  6. NOTE: Pre-construction meetings for the Third Party Inspection Program can be arranged by contacting (301) 883-3820.  The Inspector will contact you to set up a specific date/time appointment for the pre-construction meeting.
  7. Enter the # sign again if you want your inspection for the next business day. If you wish to pre-schedule for another day (up to seven days in advance), enter the 4 digits for the month and day, mmdd# - for example October 21, 2006 would be 1021#), followed by the # sign.
  8. Listen as the system plays back your information. If all the information is correct, enter the # sign when instructed to verify. If you have detected an error, enter * when asked to verify and the system will allow you to re-enter the data. The system will then provide you with a confirmation number.  Please record your confirmation number. If you do not receive an authorization number, you will receive a message that your request is invalid. This means your inspection request has not been recorded.

General Notes: There is a 15 second time limit on each key entry. Therefore, the system may disconnect if the entry of information is delayed. If this happens, please try again. When the main computer is not operational, you will be told that there are technical difficulties. Please try again later.

Canceling an Inspection: If the work is not ready for the planned inspection, please contact the Licenses and Inspections Division at (301) 883-3820 to cancel the inspection. Inspections that are canceled are not subject to a re-inspection fee.

Additional Information: Permit case numbers that are followed by an R or C should select from the 100 series of choices. Those permit case numbers followed by an EC should select from the 200 series. Case numbers that use CGU and are in the TPIP program should contact the Commercial Construction/Life Safety Section to arrange an inspection. Failing to follow these guidelines may delay your inspection.

What type of Inspection: An inspection is required prior to concealing any new construction from view. The footing inspection is the first inspection to be made and must be completed prior to placing concrete. The footing must be free of mud and water. A foundation wall is that portion between the footing and the wood framing and is usually concrete construction. Prior to placing dirt against the foundation wall, a backfill inspection is required. The foundation drainage system must also be completed at this time. A framing inspection includes the exterior weather envelope, structural, rough electrical, sprinkler and mechanical. A WSSC plumbing rough-in sticker will be requested at this time. Following the framing inspection, insulation may be installed. Once the installation is complete, a close-in inspection occurs prior to the installation of any wall board or other interior covering. A slab inspection is required for basement, garage, driveway, sidewalk and other similar concrete inspections. When all work shown on the plans is complete, a final inspection can be requested.
