Pergola vs Gazebo: Differences, Costs, and Which Fits Your Yard

Key takeaways:

• A pergola has an open, slatted, or louvered roof; a gazebo has a solid roof and is usually freestanding, often with its own floor.
• Pergolas give filtered shade and suit patios, pool decks, and modern architecture; gazebos give full shelter.
• HomeGuide: custom pergolas run about $30 to $65 per square foot; a custom 12-by-12 gazebo runs about $8,600 to $14,400.
• Motorized louvered pergolas offer the best of both: open for sun, closed for shade and rain.
• In the City of San Diego, many patio covers under 300 square feet can be exempt from a building permit, but the exemption disappears in the Coastal Zone or with electrical work.

Pergola vs gazebo is a common question when homeowners want shade over part of the yard. Both create an outdoor room, but they look, feel, and cost differently, and the right choice depends on how you will use the space. At Modern Yardz, we design and build pergolas and patio covers across San Diego County.

This guide compares structure, shade, placement, cost, and permits, and explains where louvered pergolas fit in.

What is the difference between a pergola and a gazebo?

The roof. A pergola's roof is open: beams, slats, lattice, or adjustable louvers that let sunlight and air through. A gazebo has a solid roof, typically pitched or domed, that blocks sun and rain completely.

Which is better for shade in San Diego?

For most San Diego patios, a pergola gives the right kind of shade. Our mild climate and frequent sun reward filtered shade and airflow, and a pergola keeps a patio bright while cutting glare. Inland, where afternoons get hot, a denser slat pattern, shade cloth, or a louvered roof adds more protection.

A gazebo makes more sense when you want a true sheltered room away from the house - a spot at the end of the garden, a dining pavilion, or a place to sit during the occasional rain.

What about louvered pergolas?

A motorized louvered pergola is a hybrid: open like a pergola, closed like a gazebo. Aluminum louvers rotate to let in full sun, filtered light, or close completely to shed rain. For San Diego's mix of bright afternoons and marine-layer mornings, they offer the most flexibility. Our aluminum pergola guide covers louvered systems in detail.

How much does a pergola cost compared with a gazebo?

Pergolas usually cost less because the roof is simpler. HomeGuide estimates:

• Pergola: A prefabricated pergola runs about $1,450 to $5,750 installed, and a custom pergola about $30 to $65 per square foot, per HomeGuide's pergola cost guide.
• Gazebo: About $30 to $100 per square foot installed, with a custom 12-by-12 gazebo around $8,600 to $14,400, per HomeGuide's gazebo cost guide.

High-end and engineered structures cost more. For Modern Yardz's aluminum pergolas, lattice styles start around $65 per square foot, solid-roof covers around $100, and cantilever designs around $125, with motorized louvered systems typically $30,000 to $60,000 depending on size and features.

Do you need a permit for a pergola or gazebo in San Diego?

Often, especially for larger or coastal structures. The City of San Diego's Information Bulletin 206 explains when patio covers on single-family lots can be exempt: generally up to 300 square feet, under 12 feet tall, and at least 5 feet from property lines. The exemption does not apply in the Coastal Zone, over 300 square feet, above 12 feet, or where the structure encroaches on a setback, and integrated electrical needs its own permit.

Gazebos with solid roofs are evaluated similarly as accessory structures. Your designer should confirm requirements for your lot and any HOA rules before you order materials.

Which should you choose?

Choose a pergola if:

• You want filtered shade over an existing patio, deck, or outdoor kitchen.
• You prefer a modern or Mediterranean look attached to the house.
• You want to integrate lighting, fans, or a louvered roof.

Choose a gazebo if:

• You want a fully covered, freestanding retreat away from the house.
• Rain and full sun protection matter more than light.
• Your home's style is traditional or garden-oriented.

Choose a louvered pergola if you want both, and the budget allows.
