Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.

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.

There are several methods for attaching stair stringers to a deck. The best way is to bolt the stringers to the deck joists using three carriage bolts in a triangular pattern. This method offers the sturdiest fit for stairs that won’t budge. Alternatively, attach the stringers to the deck rims using lag bolts or to the posts using adjustable slope hangers.

Yes, deck pier blocks can be used as an alternative to traditional deck footings, particularly for small or low-to-the-ground decks. Unlike poured concrete and buried post footings, deck blocks don’t require digging or pouring. However, their use is regulated by local building codes, and they may not be permitted in areas prone to high winds, earthquakes, or hurricanes. Always consult your local building codes before choosing them for your deck project.
