Get matched with top patio pros in Fort Wainwright, AK

A concrete base—or concrete footings, more specifically—is necessary for a freestanding pergola build. A pergola is top-heavy and can’t stand on its own, so it will always need some type of base or support. If you’re attaching a pergola to a deck, the deck’s supportive joists will act as the support, so there will be no concrete base or footings necessary.

While some areas may allow for a slope of up to 20%, this is often the maximum slope for driveways, with a few exceptions of up to 25%. Other regions may have a maximum of 12%, 15%, or 18%, so check with your local building department to ensure you’re laying a driveway that is up to code for your location.

In most cases, you will need a building permit for cement work on your property. You need a permit for any project that adds a permanent foundation on your property—which, in most cases, includes even a flat slab of concrete poured directly on the ground. Building permits for concrete projects usually cost between $100 and $500, although this can get higher for larger projects. You can always ask your cement company if a permit is necessary for your project, and the expert will typically pull the permit for you to save you time and energy.

Generally, a patio is more accessible than a standard deck because patios are constructed at ground level. However, decks can be made accessible by adding a wheelchair-accessible ramp, a vertical lift, or a stair lift along the entry. An ADA-compliant deck ramp costs about $3,000 on average. The additional investment will provide a much friendlier experience for your guests with movement impairments.
