Construction and building inspectors inspect new or remodeled structures. They make sure work meets code requirements.

Before construction begins, examiners determine if plans comply with codes and regulations. They approve plans that meet codes and reject those that do not. They also issue building permits for approved plans. Construction cannot begin until permits have been issued.

Building inspectors visit the worksite before workers pour the foundation. They inspect the soil condition to ensure it can support the foundation. They also check the position and depth of the footings. Later, they return to the site to check the completed foundation.

The number of other visits depends on the size and type of structure. In general, inspectors visit to check systems, such as plumbing and electrical, before they are covered by additional construction. Inspectors make a final inspection when the project is completed.

Inspectors often do visual inspections to check structures. Their experience enables them to spot problems. They sometimes measure dimensions and compare them to those specified in building plans. Inspectors also check safety systems for correct installation. Inspectors witness smoke control and fire systems tests along with the fire marshal.

When inspectors find problems, they note the code violation. They notify builders and city building agencies. Inspectors confer with these groups to explain regulations. If builders do not agree, inspectors may need to explain their decision to the building codes division. Inspectors review builder complaints and gather evidence.

Inspectors maintain daily logs and inspection records. They also prepare reports.

There are many types of inspectors:

• Electrical inspectors check electrical installations to be sure they operate properly and safely.
• Mechanical inspectors check heating, ventilation, and cooling systems.
• Plumbing inspectors examine pipes, fixtures, water supply, and waste systems.
• Public works inspectors inspect sewers, dams, bridges, and highways.

Some inspectors conduct tests for environmental hazards like mold, asbestos, or poor air or water quality.
