Christchurch District Plan
If the deck is attached to the dwelling in a Residential Suburban, Residential Suburban Density Transition, Residential Hills or Residential Large Lot zone, and is at ground floor level or below, it can be constructed right up to the internal property boundary as long as any parts within 1m of the boundary are 300mm or less in height.
If the site is within the Residential Banks Peninsula zone, it must be set back either 2m or 1.5m from the internal boundary, depending which boundary is involved. In the Residential Small Settlement zone the deck must be set back 3m, or 2m if your property is in the Spencerville and Kainga overlay areas. In all zones, a larger front yard setback is required.
If the deck is at first floor level or above, it must be set back at least 4m from internal boundaries in most Residential zones and certain distances from road boundaries (depending upon District Plan zone requirements).
If one of your boundaries is along a stream or waterway you will need to check the waterway setback rules. The setback distance varies depending on the type of waterway. A resource consent is required to build a deck or other similar structure within the waterway setback.
The deck must comply with site coverage (if higher than 800mm or covered/roofed), height and recession plane requirements applicable to the zone.
