Decks require several inspections during and after the building process, but the specifics vary depending on where you live. Most areas mandate that decks comply with local building codes and safety regulations for the foundation, framing, and structure. Some pros recommend a footing inspection, which verifies the depth, width, and location of the various footings to ensure they offer enough foundational support.

Expect to spend around $10,000 to $11,000 to replace a 20-by-20-foot deck. Using high-end materials like composite or exotic hardwoods can drive up the cost, as can custom features and design elements. You can also expect to pay more than average if your deck replacement requires a site evaluation or if you need the work done during the busy season.

Whether you need a permit depends on the deck design and local regulations. Most areas mandate a building permit if the deck is over a specific height or if it's attached to a pre-existing structure. Shorter, freestanding decks may not require a permit, but you should check with local zoning ordinances and your homeowners association for specifics.

The best direction for a gate to swing depends on its location and purpose, but swinging inward is the general rule. An inward swing is often considered safer, prevents the gate from opening into public spaces like a sidewalk, and may be required by local building codes.

There are exceptions and specific considerations. If your property is on a slope, an inward swing might not be possible. For a deck gate, it's safest to have it swing away from any steps. In a backyard, the direction can be a matter of preference, though an inward swing can be helpful when carrying heavy items like a wheelbarrow into a garden.

Regardless of direction, ensure the gate can open fully without hitting any objects or blocking spaces. While an inward swing is standard, a gate that can swing both in and out offers the most flexibility if your setup allows for it.
