The Design

Complex designs with not-so-common shapes or styles cost more to build than simple designs.

The Time of the Year

Lumber prices fluctuate all year long as well as the fees for deck builders, they may increase during peak season.

The Foundation

The material you choose for the foundation plays a key role in the overall price, including whether you stick with redwood or go with a less expensive material. Whichever material you select, you must treat it to withstand insects and the elements.

Building Permit

Depending on your local regulations, you must obtain a permit at an additional cost. Most contractors will handle the permitting process, but homeowners will pay the fees.

Your Location

Redwood is native to the West Coast, making building a deck in some parts of California and Oregon less expensive than in Maryland because of transport costs.

Other Factors

The railing material, stairs, lighting and whether or not you’d like a hot tub add to the total cost of the deck.
