I once had a builder in Newtown ring to ask if he could just send photos instead of booking an inspection, because the drainage trench was already backfilled. The answer was no, and it is always no, and that single fact causes more re-digging than anything else in outdoor construction. Council inspections exist to look at work while it is still visible. Once it is covered, a photograph proves the trench existed. It does not prove the pipe was laid to fall, bedded correctly, or connected to the right outlet.
What an inspector is actually looking for outdoors
On a typical outdoor job, there are a handful of stages where an inspector wants eyes on the work before it disappears. Foundation and footing excavations get checked for depth and for reaching a bearing layer the ground can actually carry — not an assumed depth on a plan, but the actual soil or rock in that hole. Reinforcing steel gets checked for size, spacing, and concrete cover before the pour, because none of that is verifiable once concrete has gone over it. Drainage pipe gets checked for fall, bedding, and jointing before backfill, since a pipe laid to the wrong grade will hold water or silt up long before anyone notices from the surface. Wellington City Council’s building consents and inspections information lists which stages on a typical job need a booked inspection rather than a self-certified sign-off.
Why “cover it and photograph it later” does not work
A photo taken through an open trench can look convincing and still miss the one thing that matters, because a camera cannot measure fall or verify compaction under a pipe. Inspectors are trained to check specific, sometimes small details — cover depth over reinforcing steel, the compaction of bedding material, whether a subsoil drain actually falls to an outlet rather than sitting flat. None of that survives in a phone photo taken from above. Councils generally will not accept photographic evidence in place of a booked inspection for those concealed stages, and if work gets covered before the inspection happens, the usual outcome is digging it back up, which costs far more than the delay would have.
The most common reasons an outdoor inspection fails
A handful of issues account for most of the “not ready” outcomes I signed off on outdoor sites. The site was not actually ready — trenches partly backfilled, formwork not braced, nobody present who could open the work up if asked. The wrong depth or grade had been used against the approved plans, often because a site’s actual fall did not match the drawing and nobody had gone back to check it. Reinforcing steel was under-covered or wrongly spaced, which is invisible once concrete goes on. And documentation was missing — a producer statement from an engineer, a compaction test result, something the consent had specifically required as evidence rather than a visual check. Most of these are avoidable by reading the consent conditions before the inspector turns up, not after.
What this has to do with selling the house later
A code compliance certificate, or CCC, is the council’s confirmation that inspected building work was completed to the consented design. For outdoor structures like retaining walls and decks that needed a building consent, a missing CCC is one of the more common issues that surfaces in a pre-purchase check years later, and it can hold up a sale while the current owner scrambles to get the original work signed off or, if that is not possible, engages an engineer to assess it after the fact. Whether a wall needed that consent in the first place is its own question, covered in retaining wall heights and when you need a design. The inspections along the way are what earn a CCC. Skipping one, or covering work before it happens, is usually why one never gets issued in the first place.
Frequently asked questions
Can I submit photos instead of booking an inspection? Generally no, for stages that are about to be concealed — councils want the actual work checked in person before backfill or a pour, not a photographic record of it.
What happens if work is covered before an inspection? The usual result is uncovering it, whether that means digging out a drain trench or, in serious cases, exposing reinforcing steel that was poured over before it was checked.
Does every outdoor structure need a code compliance certificate? Only work that needed a building consent in the first place gets a CCC; rules vary by council, so it is worth checking against your specific consent rather than assuming.
