Building consent guide
Do you need consent for a pergola in the Palmerston North City Council area?
An open, unroofed pergola usually doesn't. A roofed cover - a canopy, louvre roof or metal-roofed pergola - only avoids consent if it fits the awning or carport size limits; otherwise it needs a building consent. Here are the national rules, where to check with Palmerston North City Council, and how we help.
The short version
- Open, unroofed pergola: exempt at any size.
- Roofed cover attached to the house (an awning under the rules): up to 20 m² exempt; 20-30 m² at ground level if a licensed building practitioner or chartered engineer is involved.
- Carport with at least one open side: up to 20 m² exempt; 20-40 m² with a licensed building practitioner or chartered engineer.
- Anything larger, or fully enclosed like a sunroom: building consent needed.

Checking with Palmerston North City Council
Enclosed structures such as sunrooms are more likely to need consent than an open pergola. Where consent is needed, we tell you at the measure, before you commit.
