Plans on Job Site
In addition, you will be required to keep a set of approved plans on the job site for review by the Construction Code Official when he or she comes to perform an inspection. The Construction Code Official will need to compare what is being constructed to the approved plans to ensure that the work is being done properly.
Remember, it is your responsibility to call into the Norristown Code Enforcement Department at 610-270-0441 to schedule inspections. If fail to call in for a required inspection, the next time the Construction Code Official visits the job site, you may be required to dismantle some of your work so the official can adequately evaluate the job. This can unnecessarily delay the completion of your project.
