Set the width and length of your pergola, choose a structure material, and pick a roof style — a standard open-beam top, a retractable fabric canopy, or an adjustable louvered roof. Tick professional installation if you want it built for you, and mark whether it attaches to the house. The calculator estimates structure materials, roof and features, labor, and a total, using 2026 national-average rates.
What Drives Pergola Cost
Material and roof style move the price the most. Pressure-treated wood is the budget choice at around $30 a square foot for the structure; cedar and redwood run higher for their looks and rot resistance; vinyl and aluminum cost more up front but shrug off sun and salt with almost no upkeep. A standard open-beam roof adds nothing extra, a retractable canopy adds a moderate amount, and an adjustable louvered roof is the premium option because of its motorized, watertight slats.
Attaching the pergola to your house (a ledger-mounted or wall-mounted design) uses fewer posts and footings, trimming roughly 15% off the structure cost. Professional installation adds labor but gets you engineered footings and a permit where required.

San Diego's year-round sun makes a pergola one of the best-value outdoor upgrades — shade over a patio or deck that you use every month. Aluminum and vinyl hold up best near the coast, while cedar suits inland yards. We design and build custom pergolas and covered decks to match your home, and can fold one into a full deck design.

Frequently Asked Questions
How much does a pergola cost in San Diego?
Most pergolas run about $4,000 to $12,000 installed, depending on size, material and roof. A 12x12 pressure-treated open-beam pergola starts near $4,300 in materials; aluminum or louvered roofs cost more.
Is a wood or aluminum pergola cheaper?
Pressure-treated wood is the cheapest up front. Aluminum and vinyl cost more initially but need almost no maintenance, which often makes them cheaper over 15 to 20 years, especially near the coast.
Does an attached pergola cost less than freestanding?
Usually yes. An attached, wall-mounted pergola uses the house for support and needs fewer posts and footings, saving roughly 15 percent on structure materials.
Do I need a permit for a pergola in San Diego?
Often yes, especially for attached structures or larger freestanding ones. We confirm the requirement and pull the permit as part of the build.
