Many hillside and edge neighborhoods are in High/Very High Fire Hazard Severity Zones, where Zone 0 rules restrict combustible fencing within 5 feet of the home. Non-combustible aluminum is the right material there; vinyl can be used on runs farther from structures.

Generally a 6-foot fence in rear and side yards is allowed without a building permit, with front-yard limits and corner-lot visibility rules in play. We confirm Simi Valley’s standards and pull permits as required.

It can, as long as it’s built for the load – we reinforce posts and footings so solid vinyl privacy panels withstand Simi’s gusts. For the most exposed lots, we may suggest a partially open design or aluminum to reduce wind pressure.

Quality UV-stabilized vinyl resists fading and brittleness, and powder-coated aluminum handles the heat without issue. Both stay low-maintenance through Simi’s hot summers, unlike wood which dries and cracks.
