Use Technical Chat when asking about building regulations for the entire nation, a province, or a singular municipality. This chat does not process single addresses.
This includes topics like:
Technical Chat is ideal when you don’t seek information about a specific plot, and you're looking for general rules and best practices that apply across multiple locations.
You will get answers based on public technical documentation, including national legislation and policy documents. These responses often include citations with direct links so you can verify the source yourself.
**⭐** Tip: Use Technical Chat when your question isn’t tied to a specific address, or when dealing with national frameworks and policy-level questions.
**⭐** Tip: If the model did not understand the intent behind the question, try rephrasing it, making it as explicit as possible. Adding more explanation about the reasoning behind your question can help our system get you to what you’re looking for.
**⭐ Tip: You can provide additional context about your question using the filters at the top of the chat window such as the municipality and province you want information for.**
