That’s right. Most homeowners policies have a coverage called “Contents”. This is generally a percentage of the total value of the home. (The percentage varies by carrier, program, etc). But it is fairly substantial. It covers everything except for a handful of excluded items which you’ll find in your Exclusions language.
For a non-business use, you’ll probably be fine if it gets stolen or the neighbor spills his beer into it.
But the total Contents coverage may not cover certain things - fine arts, wine collections, etc. not because the item isn’t covered but because the value of those might be more than your coverage. For that situation you can get separate riders to up coverage for that specific class of contents.
Electronics may have a limit but that’s more likely found in auto policies than homeowners now due to the proliferation of high-end electronic devices.
OTOH, if the house burns to the ground, you may not have sufficient coverage for all of the things you have. The percentage of home value used to figure contents coverage may not be sufficient due to your purchase habits being different from other people in similar homes. So you might take a look at adding everything up and figuring out how that correlates to your contents coverage. But that’s not a GF/laser specific issue.
BTW, many policies will have separate coverage for outbuildings and their contents so if you’ve got it in a detached shop building there’s a whole nother set of coverages to look at
People with home based businesses need to check with their agent or carrier. Some don’t care as long as the public is not coming to you (e.g. you operate an Etsy business) or aren’t producing food or cosmetic products or if you’re under a certain revenue threshold. The logic being that it’s not worth the effort to worry about someone who occasionally takes the neighbor’s dog in for a weekend for $100 or the Etsy sales of knickknacks. The exposures come from things with chance for significant liability - customers on premises, food or cosmetic products causing allergic reactions or poisonings, etc. For the risk that a GF adds to a homeowner (absent the public coming over every day), even if they decide you need some sort of commercial cover, it’s going to be minimal in cost (or you need a new carrier).
