Don’t own your home, or don’t think you have the skills to update it? You don’t need to hire a handyman or ask the landlord’s permission for these home-improvement hacks.I cover home improvement for Wirecutter, and while I think that most people are more intimidated by power tools and drilling holes in their walls than they ought to be, I also have to admit that there are plenty of great, nonpermanent ways to upgrade your space.My colleagues and I have rounded up a heap of our favorite DIY projects for renters (and commitment-phobic owners), each based on comparative testing and years of experience on our beats and in our own homes. Most of these can be completed in an hour or less, often without any tools, and they’re all easy to undo at the end of a lease — likely without gambling your security deposit.
