Usually, if storefront signs or logos are just incidental background elements in a photo taken in public, that is generally considered acceptable. In many places, images of things permanently visible in public may be allowed under concepts like freedom of panorama, and minor/incidental inclusion may also be treated as de minimis.

Trademark issues are more likely if you use the photo in a way that suggests the brand endorses you or your work. Copyright or trademark concerns are also more likely if the sign or logo is the actual subject of the photo rather than just part of the wider scene.

So for ordinary street or city photos, background signs are usually not a problem. But the exact rules vary by country, and “fair use” is mainly a US legal concept, so if your intended use is commercial or legally sensitive, get advice from a qualified local lawyer.
