The proper height for a stair riser or deck step is between four and seven inches, with seven inches often considered the most comfortable. Building your stairs to this height ensures a strain-free step position and minimizes the risk of trip and fall injuries. For optimal safety and comfort, especially on deck stairs, a rise of around seven inches should be paired with a tread depth (or run) of at least 10 to 12 inches. While it is possible to design stairs with risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. Always check with your local building codes, as they may mandate specific dimensions that differ from these general recommendations.

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.

You should refinish your deck to maintain its appearance, durability, and longevity. Refinishing your deck protects the wood from foot traffic and the elements. It also helps extend its life span by keeping rot, mildew, and termites at bay. By maintaining your deck, you can avoid the cost of replacing your deck sooner. A refinished deck also looks great and restores some of its original beauty.

No, you don’t need a permit to repair and replace a few boards on an existing deck. However, if you’re making structural changes to the deck or tearing down the old one and building a new one, you will likely need a permit. Check with your local municipality for the regulations and rules in your area, or ask a local contractor who builds decks for advice.
