Pergola Cost Guide (2026): What to Expect for Materials and Installation

A pergola adds usable outdoor living space and, depending on the materials and design, can meaningfully increase the appeal of a backyard. The cost range is wide — $1,500 for a kit pergola you assemble yourself, to $30,000 for a large custom structure with a louvered roof and electrical — so knowing what's driving the number is essential before you get bids.

What Pergolas Cost

Kit pergola (self-installed): $1,500–$6,000 for materials only
Professionally installed kit: $3,000–$8,000
Custom-built wood pergola: $5,000–$14,000
Custom aluminum or steel pergola: $6,000–$16,000
Louvered pergola (motorized adjustable roof): $10,000–$30,000+

Per square foot installed:

• Basic pressure-treated wood: $25–$40/sqft
• Cedar or redwood: $40–$70/sqft
• Aluminum (powder-coated): $45–$80/sqft
• Louvered/motorized system: $90–$200/sqft

A 12x16 foot pergola (192 sqft) — a common size for a patio — typically runs $4,800–$13,400 professionally installed depending on material.

Pergola Types

Open Lattice / Traditional Pergola

The classic pergola: vertical posts supporting horizontal beams with rafters running perpendicular on top, spaced to create dappled shade. Provides partial coverage (30–50%) without blocking full sun. Most pergola kit systems use this design.

Best for patios and decks where some sun is welcome, or where you'll grow climbing plants (wisteria, climbing roses, jasmine) over the structure.

Solid Roof Pergola (Covered Pergola)

Boards, polycarbonate panels, or a solid roof over a pergola frame. Provides full weather protection, extending the usable season of the space. Sometimes called a "patio cover" depending on the municipality.

Note: a solid roof pergola in most jurisdictions triggers a building permit and setback requirements. Open lattice pergolas sometimes avoid this threshold, but check with your local building department before assuming.

Added cost for solid roof: $2,000–$8,000 depending on material (polycarbonate panels vs. shingles vs. corrugated metal).

Louvered Pergola

Motorized aluminum louvers that rotate from fully open to fully closed with a remote or app. Lets you control sunlight and close for rain protection. The Azenco, StruXure, and Equinox systems are common in this category.

These are the premium tier. Budget $15,000–$30,000 for a professionally installed louvered system on a moderate-sized patio, plus potential electrical for the motor and lighting.

Attached vs. Freestanding

Attached pergolas connect to the house at one end, using the house wall or a ledger board as structural support. They integrate with the existing structure and often feel like an extension of the home. They require proper flashing where they attach to prevent water intrusion.

Freestanding pergolas stand independently from the house. They require four posts with footing foundations (or weighted base systems on concrete patios) and can be placed anywhere in the yard.

Materials

Pressure-Treated Pine (PT)

The least expensive wood option. Treated with preservatives that resist rot and insects. It will warp, check (develop surface cracks), and gray over time unless painted or stained annually. Not as aesthetically clean as cedar or redwood but significantly less expensive.

Cost premium over kit: None — most entry-level kits use PT.
Maintenance: Annual sealing/staining to preserve appearance.

Cedar

Naturally rot-resistant, dimensionally stable (warps less than PT), and takes stain well. The standard for mid-range custom pergolas. Western red cedar is the most common species used.

Cost: 30–50% more than PT for equivalent structure.
Maintenance: Seal every 2–3 years.

Redwood

Similar properties to cedar, slightly more durable, typically more expensive and less available outside the western US. Premium appearance.

Cost: Similar to or slightly more than cedar.

Ipe and Hardwoods

Tropical hardwoods (ipe, teak, cumaru) are extremely dense and naturally resistant to rot and insects without chemical treatment. Very long lifespan. Expensive and require specialized fasteners (pre-drilling required to avoid splitting).

Cost: 2–3x cedar for equivalent structure.

Aluminum (Powder-Coated)

Low maintenance, no rot, no warping, and can be designed to closely mimic wood appearance. Most louvered systems use aluminum. Heavier gauge aluminum structures feel solid; thinner-gauge systems feel hollow.

Cost: Comparable to mid-range cedar to high-end hardwood, depending on system.

Vinyl / PVC

Some kit manufacturers offer vinyl pergolas. They require no painting and resist moisture, but they can flex more than wood under load, look less substantial, and are harder to repair if damaged.

What Drives the Cost

Size: The single biggest variable. More square footage equals more material and more labor.

Material: Cedar vs. PT vs. aluminum varies the material cost by 2–4x.

Post footings: Concrete footings add cost. A simple surface-mount post base on an existing concrete patio costs less than digging and pouring separate footings in soil.

Roof type: Open lattice is least expensive. Solid or louvered roofing adds significantly.

Electrical: Adding fans, lights, or heaters requires an electrician, adding $500–$2,500 depending on the run from the panel and number of circuits. If you're adding string lights without hard-wiring, the OHLUX 55 Ft G40 Outdoor String Lights are a top-rated plug-in option — shatterproof dimmable bulbs, waterproof, and connectable end-to-end for longer runs.

Site conditions: Sloped ground, limited access, or difficult soil adds labor.

Custom vs. kit: A fully custom pergola designed for a specific space costs 20–50% more than a kit system of equivalent size but typically looks more integrated with the home.

Permits

Whether you need a permit depends on the jurisdiction, the size of the structure, and whether it has a solid roof.

General rules (always verify with your local building department):

• Freestanding open pergolas under 200 sqft often don't require a permit
• Attached pergolas almost always require a permit (they're attached to the structure)
• Solid roof pergolas / patio covers require a permit in most jurisdictions
• HOAs may require separate approval independent of city permits

Getting a permit means inspections, which means the footings and structure will be verified. This protects you — unpermitted structures can complicate home sales and insurance claims.

HOA Considerations

If you have an HOA, check the CC&Rs before purchasing materials or signing with a contractor. HOAs commonly regulate:

• Setback from property lines
• Maximum height
• Approved materials and colors
• Screening requirements (must the structure be hidden from the street or neighbors?)
• Timeline for approval before construction

HOA approval can take 30–90 days at some associations. Build this into your timeline.

What to Include in a Pergola Bid

A complete pergola bid should specify:

• Exact dimensions (length x width x height to top of rafters)
• Material species and grade (e.g., "Western red cedar, select grade, 6x6 posts, 4x8 beams")
• Post base type (surface mount vs. in-ground footing)
• Footing size and depth if concrete is poured
• Roof type (open lattice spacing, solid panel material, or louvered system model)
• Hardware (stainless steel or galvanized for exterior)
• Electrical rough-in included or excluded
• Paint or stain included or separate
• Permit pulled by contractor or owner

If the bid says "cedar pergola, 12x16" with no further specification, ask for the detail above before comparing against other bids.

Cost Reference

Get at least two bids with identical specifications. The materials differ significantly in quality, and a lower bid often reflects thinner lumber, lower-grade cedar, or lighter-gauge hardware.
