Deck railing installation in Sparks, NV

Residential guardrails have a minimum height measured from the deck walking surface, and guards are generally required once that surface is more than 30 inches above the ground below. Stair guards are measured differently, from the nosings of the treads.

The specific figures come from the code edition your jurisdiction has adopted, and Northern Nevada jurisdictions adopt regional amendments on their own schedule. Confirm the current numbers with your building department before ordering posts — it is a cheap phone call and an expensive assumption.

Nine times out of ten the posts are lag-screwed to the side of the rim joist with no blocking behind them. Screws in that position resist very little leverage, and every lean gradually enlarges the holes.

The fix is to through-bolt the posts and add blocking so the load spreads into the joists. It usually means lifting a few deck boards, which is why it is much cheaper to do at build time than afterwards.

It works well and it is popular for exactly the right reason: on a foothill lot in ArrowCreek or above Washoe Valley, the view is the point, and cable disappears in a way that balusters cannot.

The caveats are real though. Tension pulls end posts inward, so corner and terminal posts need to be sized and braced for it. Cables need re-tensioning, particularly in the first year. And with big daily temperature swings the tension itself moves, so this is a system that wants checking rather than forgetting.

Usually, but the honest first question is what the posts will attach to. Older decks often have a rim board that was never intended to carry guard loads, and sometimes the framing simply is not there. Adding blocking means lifting deck boards along the perimeter.

It is a normal job. It is just rarely as quick as it looks from above.

A guard is the barrier that stops you falling off the edge. A handrail is the thing you grip going up and down stairs, and it has to be graspable — a specific profile and size your hand can close around, with returns at the ends so a sleeve cannot catch.

A flat top rail is a guard, not a handrail. Stairs generally need both, and a top rail doing double duty is one of the more common reasons a deck fails inspection.

Replacing an existing guard like for like is often treated as maintenance; adding a guard where there was none, or altering the structure to carry one, moves towards permitted work. Because guards are a life-safety component, inspectors take a closer interest in them than in decking.
