How does fair use apply to architectural drawings and designs?

Fair use can apply to architectural drawings and designs when the use of these works meets specific criteria, such as purpose, nature, amount, and effect on the market. For example, using an architectural design for educational purposes, commentary, or criticism may qualify as fair use if it doesn't significantly affect the market value of the original work. However, commercial use or reproduction of entire designs without permission is less likely to be considered fair use. Ultimately, each case is evaluated individually based on its circumstances.
