🧾 Overview
Most residential pergola installations do not require a permit when they’re below a specific size threshold and installed on an existing patio or deck.
However, local rules vary — especially if your pergola is attached to a structure, includes electrical wiring, or exceeds 200 sq ft in total area.
▼ When a Permit Is Typically Not Required
Freestanding pergolas under 200 sq ft (common in most U.S. municipalities)
Installed on existing patios or decks without new foundations
Manual models (non-motorized) with no electrical connection
💡 Example: Two 10 × 10 ft pergolas (total = 200 sq ft) often qualify as exempt structures.
▼ When a Permit Is Usually Required
Structures exceeding 200 sq ft
Pergolas attached to a home or other building
Models with hard-wired electrical components (motors, lighting, heaters)
Commercial or multi-unit property installations
