Yes, but only slightly if at all.
If you’re wondering why buy a storage building at all. To put it another way is a storage shed a good investment?
This highly depends on what you are using the building for. Are you using the storage shed for business purposes, to enhance a rental property, or storage? A better question to ask is: “would a storage building increase your enjoyment and/or convenience of use of your property?”. If the answer to this question is YES! Then a storage shed may be worth investing in regardless of if storage buildings increase property value.
Who to contact?
If your wanting to know some idea how much possible value a storage building will increase your property, you can call your local tax appraisal office to see how they appraise and assess value of storage buildings, either for residential or commercial properties.
