Do I need a resource consent to build a deck or cut down a big tree?

Different rules can apply, so check before starting. Building work is regulated under the Building Act 2004, where some low decks are exempt from a building consent, but the work can still need a resource consent if it breaches your district plan rules on height, site coverage or boundary setbacks. Trees may be protected under the district plan as notable or heritage trees, and some areas have rules on vegetation clearance near waterways or on coastal sites. Look up your property's zoning and rules on your council's district plan map, or ask the council duty planner in writing. Note that the Resource Management Act 1991 is being replaced by new planning legislation, so confirm which regime applies at the time. Working without a required consent can lead to enforcement orders and fines.
