Closet design services include help designing and laying out your closet for maximum utility, visual appeal, and return on investment. Many closet designers can also include the carpentry required to construct your custom closet. You should speak with your designer beforehand to determine what services are included in the estimate, and prepare to lay out additional funds for materials or labor as needed.

Bump-out additions can add some space to a closet without requiring any significant structural work. This entails pushing back the existing rear or side of the closet, simply moving the wall into either an adjacent room or unused space. For ground-floor closets, this could even be extended to the exterior of the home, but that has its own complications. Bump-outs are a good discussion to have with your contractor if you’re just looking to increase the space a little—not renovate the entire closet space.

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 design your own closet, but it’s usually better to hire a professional to do the work for you. Not only will you get years of design experience to guide you toward the right layout and material choices, but you’ll also only pay slightly more hiring a professional than you would creating your own plans and hiring a carpenter. A high-quality closet designer can provide insight into how to lay out your closet, and they may be able to find you a good deal on the carpentry or complete the work using an affordable, in-house team.
