What you need approved, who does the submitting, and why this — not construction — is usually what delays a start.
Why this matters more than clients expect
On most projects we work on, the approval process rather than the construction determines when you can start. Clients budget carefully for the build and treat approvals as paperwork that happens in the background. It does not.
Building without approval is also a genuine risk, not a technicality. It can result in enforcement action, difficulty connecting utilities, problems obtaining insurance or financing, and a serious obstacle whenever you come to sell.
What a submission usually involves
The detail varies between counties and with the size and nature of the project, but a typical building approval submission is assembled from:
- Proof of ownership for the plot, and confirmation that the intended use matches how the land is zoned
- Architectural drawings prepared and signed by a registered architect
- Structural drawings and calculations from a registered structural engineer
- Drainage and services proposals
- Environmental assessment where the project’s scale or nature requires it
- The relevant county submission forms and fees
Because the drawings must be prepared and signed by registered professionals, this is not something a client assembles alone. Either you appoint the consultants directly, or you appoint a design-and-build contractor who appoints them as part of one contract.
Zoning is worth checking first
Before spending anything on drawings, establish what your plot is actually zoned for and what density is permitted. Plot ratio, ground coverage, setbacks and height limits vary considerably by area, and they determine what can be built at all.
Discovering after a full design that the permitted density will not support the scheme is an expensive and entirely avoidable way to learn this.
How long to allow
Approval timelines vary with the county, the completeness of the submission and the complexity of the project. The single biggest factor within your control is submission quality — a complete, correct first submission moves considerably faster than one that generates queries and a resubmission.
Plan for approvals to take real months rather than weeks, and do not commit to a handover date, a tenancy or a loan drawdown that assumes otherwise.
Approvals do not stop at the permit
Approval to build is the start of an obligation, not the end of one. Expect county inspections at defined stages, separate registration of the project with the NCA, and — depending on the building — an occupation certificate before it may lawfully be used.
Utility connections have their own processes and their own lead times, and they are best started earlier than feels necessary.
