Review the design plan before beginning deck construction. Build the deck in several stages, and gather tools and materials for each stage before beginning. Arrange to have a helper for the more difficult stages.

Check with local utilities for the location of underground electrical, telephone, or water lines. Apply for a building permit, where required, and make sure a building inspector has approved the deck design before beginning work.

The time it takes to build a deck depends on the size and complexity of the design. A rectangular deck, about 10 ft. × 14 ft., can be completed in two or three weekends.

1. Install a ledger to anchor the deck to the house and to serve as reference for laying out footings. Use batterboards and mason's strings to locate footings, and check for square by measuring diagonals.

2. Pour concrete post footings, and install metal post anchors. Set and brace the posts, attach them to the post anchors, and mark posts to show where beam will be attached.

3. Fasten the beam to the posts. Install the outside joists and header joist, using galvanized nails.

4. Install metal joist hangers on the ledger and header joist, then hang the remaining joists. Most decking patterns require joists that are spaced 16" on center.

5. Lay decking boards, and trim them with a circular saw. If desired for appearance, cover pressure-treated header and outside joists with redwood or cedar facing boards.

6. Build deck stairs. Stairs provide access to the deck and establish traffic patterns.

7. Install a railing around the deck and stairway. A railing adds a decorative touch and may be required on any deck that is more than 24" above the ground.
