Which rules apply in Wood Green?
Here is what usually applies to a Wood Green job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.

- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- Fire precautions follow a risk assessment; the LACORS Housing – Fire Safety guide (2008) is guidance, not law, but many councils base their standards on it.
