Carson FAQ
Can I build a 7-foot privacy fence in my back yard in Carson?
Generally no in a flat-graded interior lot — the default cap is 6 ft. You may reach 8 ft only where the side/rear yard abuts another residential zone or a future right-of-way; otherwise apply for a variance.
What height can I build in front of my house?
Solid walls in the required front yard are capped at 3.5 ft. You may stack open fencing material (wrought iron, lattice) above to a combined 8 ft, but a full 6-ft solid wall in the front yard is not allowed by right.
How is height measured on a sloped lot?
Carson Code uses the higher of the two adjoining grades as the measurement reference, preventing height-stacking on retaining walls.
