This article explains what the Oregon and Washington home inspector Standards of Practice have to say (or not say) about smoke detectors and carbon monoxide detectors, highlights what some of the requirements are about each for real estate transactions (which have nothing to do with inspectors), and how Nickelsen Home Inspections, LLC handles smoke/CO detectors and alarms. At the end, we include links that may be important to you. By reading this material and checking the links, you will know what is included and not included in the inspection process and what is required during real estate transactions.
