Privacy screen in the backyard without permit

I’m seeking privacy in my backyard and was considering installing a privacy screen, similar to the one in the image. This approach would allow me to comply with the 7ft limit on the rear fence without exceeding it.

I’m wondering if this installation would require a permit or pose any concerns. I’m looking for a temporary solution that’s easy to remove if I decide not to use it in the future. I reside in the Almaden area.
