Composite decking requires a solid foundation or substructure for support. This base is typically a frame composed of posts, beams, joists, and footings. The frame can be built from various materials, such as composite, plastic, timber, or metal, depending on your budget, deck type, and environmental conditions. For maximum stability, a professional deck builder may recommend installing this frame on top of a solid concrete base. It is best to discuss the most suitable substructure design and materials for your specific project with a professional.

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.

As with patios, there are many types of deck choices to choose from to add personalization to your home. Some common deck options include:

• Attached decks are anchored to the home and include simple ground-level options or multi-level structures with stairways and separate landings. 

• Detached island decks are not attached to the home; they’re a freestanding structure in the yard. 

• Wraparound decks connect the back of the house with at least one other side and often are built with railings for safety. 

• Multi-level decks connect your deck through varying levels of elevation, featuring landings that are attached to stairs.

Homeowners should build their floating decks at least 18 inches off the ground. Having it at this height will allow for better airflow underneath and help prevent moisture-related problems like warping or rot. That being said, local guidelines for deck heights may vary depending on where you live.
