Summary
Hawthorne requires a building permit before any fence or wall goes up in any zoning classification. The rule sits in the general fence and wall standards of the zoning code, and it applies citywide regardless of height or material.
No fence or wall shall be constructed in any zone classification without first obtaining a building permit therefor.
Full Breakdown
" That covers residential, commercial and industrial lots alike, and it applies before any construction starts, not after the fact. 090 at three and one-half feet regardless of what the zone otherwise allows. 020(A)(6) before a contractor can break ground. Skipping either step leaves the fence unpermitted even if it otherwise meets the height and material rules.
Violations & Fines
An unpermitted fence or wall is a code violation the city's building and safety division can act on through a stop-work order and require retroactive permitting, removal, or modification to bring the structure into compliance. Because Chapter 17.48 folds height, material and screening standards into the same permit review, an unpermitted fence that also exceeds height limits or uses a banned material faces two separate corrections: obtaining the permit and altering the fence itself.
