The overhang, or nosing, of deck steps is another area that will be covered in building code requirements. The noses on your deck steps should have a minimum overhang of ¾ inch. For safety, usability, and code compliance, the nosing of deck steps should not extend past 1¼ inches.

Pressure-treated decks last 15 to 20 years on average, but with proper maintenance, you could get 40 to 50 years of value from yours. Reseal your deck every one to two years, and replace old or rotted wood as soon as possible to avoid structural damage. Where you live plays a role in the lifespan of your deck. Intense sunlight, rainfall, wind, and hail can reduce the deck’s lifespan.

While eco-friendly decking, also called composite decking, is a win for the environment because it consists of recycled materials, it has trade-offs. These sustainable options often come with steeper price tags, lack natural wood's warm look, and can become uncomfortably hot under full sun. Some composite materials can also become slick when wet, posing a potential hazard.

Building codes for deck railings can vary by location, so it's important to consult your local regulations before construction. Generally, a guardrail is required for any deck that is more than 30 inches above the ground.

For residential properties, the standard minimum height for a deck railing is 36 inches. However, some states and municipalities have stricter requirements; for example, California and Washington mandate railings that are at least 42 inches high. Therefore, a 42-inch railing is not considered too high and may be required in your area or chosen voluntarily for additional safety.

In addition to height requirements, codes also specify other safety features, such as the maximum spacing between balusters to ensure they are close enough to prevent a child from squeezing through.
