General Builder & Remodeller

The general builder is the one with the licence on the permit, the project to manage, and the surveyor to satisfy — a step up in money and risk from being on the tools. Here is the year-one income picture, the project benchmarks, the compliance failures that wipe a small job's profit, and what a surveyor visit actually checks. (Figures indicative 2025.)‍‌‌‌‌‌‌‌‌‌‌‌‌‌‌‍

The first-year income picture

A first-year builder usually mixes subcontract carpentry or framing for cash with a few project-managed renos:

Subcontract day rates (2025, indicative): ~$360-480/day in regional QLD, SA and TAS, ~$440-560 in VIC and regional NSW, ~$480-640 metro (Sydney, Brisbane, Perth) — supplying tools and insurances, not materials, with a year-one utilisation hit (~3-4 paid days a week).
Project-managed reno work prices as jobs, not days, with an effective $700-1,200/day once the supervision margin and subbie markup are in — but year one is constrained by limited pipeline, client trust, the cash-flow drag of deposits versus progress claims, and the learning curve on permits and sequencing.

A realistic first-year turnover is $100-180k gross (a good outcome around $140k), with an owner take-home of $60-90k after materials, subbies, insurances, vehicle and overhead. The common pattern: heavy subcontract work early for cash, weighted to one or two managed renos later to set up year two. The licence pathway itself is in Apprentice to Builder Pathway.

Project benchmarks (guidance)

Kitchen: a remove-and-replace (same layout, mid-range) $20-40k; a kitchen plus a small rear extension (new slab, exterior wall, roof tie-in) $80-150k in major cities (which triggers structural, energy and sometimes planning). First-years often win the "stage 1" rather than the full double-storey addition.
Bathroom reno: a standard one $15-35k (first-year persona typically $18-25k, keeping structural change low and using reliable waterproofers and tilers — where the risk lives).
Granny flat / secondary dwelling: a 40-60m² finished build often $120-250k — and the margin trap is that headline "kit" prices exclude services, site works, approvals and connection fees. A new builder's first granny flat is typically $150-200k straightforward suburban, and pricing aggressively before running a few smaller renos is how builders go broke.

The compliance failures that wipe profit

Starting without permits — structural changes assumed "just internal", or granny flats, decks and carports assumed exempt when they are over height or area, leading to stop-work orders, fines, certificate problems and personal liability.
Inadequate documentation — missing permits, inspection reports, as-built variations, engineering addenda or manufacturer instructions (critical if a dispute or audit arises).
Misreading the NCC — not keeping up with energy, condensation, fire-separation or accessibility updates, relying on "how we have always done it" (see NCC 2025 Overview).
Waterproofing and framing inspection failures — framing not matching the engineering (member sizes, bracing, tie-downs), or wet-area waterproofing not to spec (falls, membrane coverage, penetrations) — which can wipe the profit on a small job even when caught early.
Insurance and home-warranty gaps — starting without the mandatory domestic building or home-warranty insurance above the state value threshold, or inadequate public liability and contract works (see Home Warranty Insurance and Contract Works & Professional Indemnity).

What a surveyor visit actually checks

This surprises new builders: a building surveyor (certifier) provides independent statutory compliance oversight — not project supervision or a finish-quality check. They review the plans, engineering, energy reports, permits and product certs, and do focused on-site stage checks against the approved plans, the NCC and the conditions of consent (see Building Surveyors & Certifiers). The mandatory stages (NSW example): foundation excavation, slab preparation, frame, waterproofing verification, and final before occupation. At the frame check it is bracing, wall heights, spans, fixings, tie-downs and lintel sizes versus the engineering; at waterproofing, membrane coverage and heights, bond breakers, penetrations and falls. It is a minimum-standards-and-paperwork check, not a quality walkthrough — and in many states the owner appoints the surveyor (the builder is prohibited from doing so) to preserve independence. A first-year builder who turns up with tidy documentation, marked-up plans and readiness at each stage is already ahead of most peers.

Common mistakes

Pricing a granny flat or extension off a headline figure that excludes site works, approvals and connections.
Starting structural or "exempt" work without confirming the permit.
No home-warranty insurance above the threshold (a catastrophic gap).
Treating the surveyor as a quality checker rather than a compliance gate (and turning up not ready for the stage).
