Beyond having an inspection, it’s important to do chimney maintenance at least annually to be certain the chimney is safe to use. Cleaning the flue of any built-up particles, creosote, and soot reduces the risk of fire. Fortunately, the cost of hiring a pro to do a chimney inspection often includes a chimney cleaning, so you may not have an extra expense for maintenance.

According to the National Fire Protection Association’s Code NFPA 25 (titled “Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems”), private fire hydrants must undergo inspection once per year, with an accompanying flow test and any necessary maintenance performed on the same schedule. Keep in mind that your town, city, or county may adopt more or less strict testing requirements. 

Certified fire door inspectors should inspect fire doors. These professionals receive training to specifically assess the condition, functionality, and compliance of fire doors. They often hold credentials from groups like the Door and Hardware Institute (DHI) or the International Fire Door Inspector Association (IFDIA). While fire marshals won’t usually do hands-on inspections, they’ll check that doors are being maintained properly during routine safety audits. If a building relies on fire doors for code compliance, it needs someone who understands the details—the difference between a cosmetic issue and a safety failure—and standards to sign off with confidence.

A chimney liner isn’t required for an outdoor fireplace; you don’t technically need one if the masonry chimney uses the proper dimensions and is built to code. However, a chimney liner does serve as a protective coating for the flue. Adding a liner could improve performance, safety, and durability. In short, while not necessary, it wouldn’t hurt.
