To prevent sagging, consider both the material and the span of the shelf. Using sturdy materials such as plywood or solid wood can provide better support than particleboard. Additionally, limiting the shelf span to 36 inches or less can reduce the risk of sagging. For longer shelves, incorporating center supports or brackets can offer additional reinforcement.

You may need a building permit to add a closet, depending on the size and kind of work required to install it. The most likely scenario requiring a permit involves changing the structure of the house and performing electrical work for closet lighting. A permit can cost between $100 and $450. If you’re installing a smaller reach-in closet, a permit may not be required, but always check with your local municipality and consult a closet designer or builder.

You can budget a little less money for how to build a closet with wire shelves than with wood shelves. Some people don’t like the aesthetics that wire shelves provide, though, meaning they’ll gladly spend a little more to add wood shelves to the build. If you decide to buy pre-made wire shelves instead of building custom-sized wood shelves, you’ll be restricted in the closet shelving dimensions you can use.

You can turn an adjacent room into a walking closet by just rearranging the room. This means removing the furniture and adding racks and an island in the center if you have that in your budget. Houses with two bedrooms connected to each other are great options for large walk-in closets that don't require any structural changes or much building whatsoever.
