Arborists questions, answered by experts

Pergolas have no base structure to hold them up, so it’s necessary to attach them to some type of foundation. Most pergolas require a minimum of at least four concrete footings to keep them solid and stable in the ground. Attaching the pergola to a concrete foundation is an option as well.

Trellises offer versatility beyond just attaching to a fence because they provide privacy and shade. They can serve as standalone features in your garden or deck or as panel screens in pergolas. Plus, you can find trellises in various design options, including diamond-shaped or checker patterns, making working with trellises very creative and fun.

Pergolas and similar overhead outdoor structures will typically be subject to building code regulations. Every municipality is different, and some may have specs or permit requirements, so it’s important to double-check. Some HOAs may also have restrictions on what you can build, so be sure to check with your HOA as well (if applicable).

Rather than using a common two-by-four piece of wood for a rafter, you probably will use two-by-six, two-by-eight, two-by-ten, or even two-by-twelve boards. Wider lumber is typically a better choice in a larger building as it provides more sturdiness. Some installers may use wider lumber for rafters near the edges of the roof, where the greatest stress occurs, and save money with narrower lumber toward the middle.

Yes, many kinds of building permits exist for various projects in and outside your home. Each city sets the permit categories, but they typically cover new construction, alterations, and demolition. For example, you will need a different permit to finish a basement than you would tear down the patio.
