Resources / Building Codes

Code, built in from the first drawing.

Every railing we design meets Washington State code from day one: guard heights, baluster spacing, glass, and load requirements. Compliance is built into the design, not bolted on at inspection time.

The standards we design to

The numbers behind a compliant guard.

Guard height

36″ – 42″

36 inches minimum for most residential guards; 42 inches in many multi-family and commercial settings.
Infill spacing

Rejects a 4″ sphere

Pickets, cables, and any infill are spaced so a 4-inch sphere can't pass through.
Cable spacing & support

3″ o.c. · supports ≤ 4′

Cables run 3 inches on center, with posts or intermediate braces close enough to hold tension and keep them from deflecting apart.
Glass

Tempered safety glass

Fully tempered, and laminated where code or exposure requires, engineered to guard-load requirements.
Guard loads

Engineered per site

Every run is engineered to Washington State guard-load requirements, including wind exposure for bluff, rooftop, and open-deck sites.
Post spacing

Up to 6′ on center

Engineered post intervals keep every run rigid and quiet underfoot while meeting load requirements.

Our approach

How we keep it compliant.

01

Designed to your project's code

We design every run to the code that applies to your specific project (residential, multi-family, or commercial), not a one-size assumption.

02

Engineered, and stamped where required

Runs are engineered to guard-load and wind requirements. When a job requires it, we arrange stamped engineering.

03

Checked before you spend a dollar

During the free consultation we confirm your framing or slab can take the guard loads, and flag any blocking or reinforcement up front.

A note: Guard requirements vary by jurisdiction and project type. These are the standards we design to; your local building department is always the final authority. When in doubt, we confirm with them before we build.
