Advertising a renovation business in the Inner West: licence rules, terraces and what converts

What can a builder legally say in an ad?

In NSW the licence number is part of the ad, not an afterthought.

Last updated 11 min readBy King St Ads Co.
The short answer

In NSW, a building trade advertisement must include the licensee name, the licence number with the correct category of work, and a business phone number. Beyond that, an Inner West tradie needs two campaign structures: search for emergency work, and a longer, proof-led path for planned renovations. Work out your allowable cost per acquired job first, then judge every suburb and channel against it. General information, not legal advice.

About the numbers on this page. Figures labelled "our audit" come from King St Ads Co.'s September 2026 review of 108 Inner West and Alexandria businesses using public ad-library listings and website checks (method and full tables). Budget figures are modelled, not observed spend. Nothing here is legal or financial advice.

What a NSW building ad has to contain

The first question is a legal one, so it comes first. NSW Government guidance on building trade advertisements (Fair Trading content) says an ad must include the licensee's name (an individual, a company, or a business name registered to the licensee), the licence number with the correct category of work, and the business telephone number. The rules cover print, internet, TV, radio and other media, so a Google ad, an Instagram post and a van sign are all in scope.

The same page says residential building work over $5,000, or specialist work of any value, needs a licence under the Home Building Act 1989. Specialist work includes electrical wiring, plumbing, draining, gas fitting, and air conditioning and refrigeration. The guidance also says an ad cannot make false or misleading statements, and cannot state a price that is only part of the cost unless the single total price is also clearly stated. It recommends keeping records of who placed each ad.

Two practical points follow. First, the licence number belongs in the ad itself, not only on the website: a responsive search ad or a short social caption needs a deliberate place for it, such as a headline, a description line or a visible text overlay. Second, the correct category matters. A builder who also does plumbing under a different licence needs the right number against the right claim.

General information, not legal advice. This summary reflects a page we read on 4 October 2026. Rules and thresholds change, and application to your business depends on your licence and your work. Check the current requirements with NSW Fair Trading or a professional adviser before you publish.

Contracts, deposits and reviews: what your ad should not contradict

NSW Government guidance on home building contracts says a written contract is required where the contract price is over $5,000 including GST, or where the price is not known but the reasonable market cost of labour and materials exceeds $5,000. It says you cannot ask for a deposit of more than 10 per cent, and that contracts over $20,000 must include a statement of a cooling-off period of five clear business days. An ad that implies otherwise, such as a promise of a large deposit discount or an instant start with no paperwork, creates avoidable risk.

Reviews are the other trap. The ACCC says it is against the law to create fake or misleading reviews or arrange for others to do so. Reviews from family, employees or paid people need their connection disclosed, incentivised reviews must be offered equally for positive and negative feedback and clearly disclosed, and negative reviews should not be suppressed or altered. Google's own Business Profile rules separately prohibit offering incentives such as free or discounted work for reviews. That makes a "10% off if you leave us five stars" note on an invoice a poor idea: it breaks Google's rule and fails the ACCC's equal-treatment expectation. Our Business Profile guide covers the review workflow.

Who you are advertising to: the Inner West's housing

The 2021 Census gives a precise picture of the housing stock a renovation builder works with. Of occupied private dwellings in the Inner West, 42.4% are flats or apartments, 28.8% are separate houses, and 27.1% are semi-detached, row, terrace or townhouse dwellings. Renters occupy 43.8%, 29.0% are owned with a mortgage and 25.0% are owned outright.

Sources: ABS Census 2021 QuickStats (Inner West); economy.id, ABS Business Register, April 2025 (GST-registered, active businesses; it excludes trusts, super funds and non-GST micro-businesses).

Read that as an advertiser. Roughly 54% of dwellings are owned, and they are the people who commission renovation work. A renter's repair need goes to the landlord or the managing agent, so a plumbing ad aimed at a Newtown renter, where 57.6% of dwellings are rented, will find mostly the wrong decision-maker. The people who call a plumber about their own hot water system are owners, and landlords. For planned work, the buyer is a terrace owner, a semi owner, or an apartment owner dealing with a strata committee. Each needs a different message.

It is also a crowded market. The Business Register counts 2,798 construction businesses in the Inner West, 11.4% of active GST-registered businesses in April 2025. In our audit of 108 Inner West and Alexandria businesses, 21 were in building, trades and construction, 17 of those 21 were independent or owner-operated, and 38% had a live audit issue. Four of the six we live-checked had no ad history on Google or Meta. Most of your competition is as time-poor as you are.

Terraces, heritage and what you can promise

A terrace renovation in Newtown, Balmain or Leichhardt is a different job from a project in a newer suburb. Council describes a heritage conservation area as significant "due to the collective nature of buildings and elements in that area", and lists more than 100 across the local government area. Council's approval guidance says that for exempt and complying development alike, consent is generally required for works on heritage items or within heritage conservation areas. A job that looks small can still need a development application, assessed on merit by a Council planner.

The local complication is that suburb names do not map neatly to one council. Newtown, Camperdown and St Peters are split between the Inner West and the City of Sydney, so two houses on opposite sides of a street can sit under different approval processes. Council points owners to the Department of Planning's spatial viewer, or to its duty planners, to check heritage status.

What this means for your advertising:

  • Never promise an approval. "We handle approvals" is a service claim you can substantiate. "Guaranteed DA approval" is a prediction you cannot.
  • Show heritage competence as proof. Photographs of terrace rear extensions, restored joinery and facade work, with a plain description of what was involved, answer the owner's real fear: that the project will stall at Council.
  • State the approval pathway on the page. A short section on "exempt, complying or DA" helps buyers and helps search engines.

Emergency work and planned work need different campaigns

Emergency (plumbing, electrical, gas)

  • Customer searches while the problem is happening.
  • Decision window: minutes to hours.
  • Channel: Google Search and your Business Profile, with a call button first.
  • Landing page: phone number, licence number, service area and hours.
  • Success measure: answered calls, booked jobs.

Planned (renovation, extension, fit-out)

  • Customer researches for weeks or months.
  • Decision window: long, with several quotes.
  • Channels: Search for the intent, plus Meta, Instagram and Pinterest retargeting for the long middle.
  • Landing page: portfolio, process, approvals, price guidance and a clear enquiry step.
  • Success measure: qualified quotes and signed jobs.

Do not run both from one campaign. An emergency plumber who bids on "bathroom renovation" is spending the wrong money, and a renovation builder who bids on "emergency" terms is paying for tyre-kickers. Keep separate campaigns, separate budgets and separate landing pages. For planned work, remember that most visitors will not enquire on the first visit: a portfolio-led page, a remarketing audience and a Houzz-style proof layer (project photos with scope, suburb and a date) carry the buyer across the gap. Our guide to Meta versus Google ads in the Inner West explains how to split that budget.

Google Local Services Ads are worth a line. Google's published availability list does not include Australia as at our check, so do not build a plan around them without confirming the current position with Google.

Suburb targeting and the catchment trade-off

Marrickville, Balmain and Haberfield do not behave alike. Marrickville has 26,570 residents and 46.6% renters at the 2021 Census, with a median personal income of $1,077 a week. Leichhardt has 15,158 residents, 40.4% renters and a median of $1,377. We have not verified census figures for Balmain or Haberfield, and we have no verified project-size data by suburb, so we do not claim to know which suburbs hold the larger jobs. Pull your own last 12 months of won jobs by suburb and compare cost per won job, not cost per click.

The wider question is whether to advertise to the Inner West only, or to Greater Sydney. Google lets you target locations by radius, with a minimum radius of 1 km, and its default location option reaches people in, regularly in, or interested in your target area. Check that setting, because an "interest" audience can pull in enquiries from outside your real service area.

Illustrative assumptionsInner West onlyWider Sydney

Cost per enquiry ($ per click divided by rate)$300$233
Share of enquiries that are qualified35%20%
Cost per qualified lead$857$1,167
Illustrative figures chosen to show the arithmetic, not benchmarks. Qualified means the right suburb, scope and budget. Test with your own numbers.

The wider catchment is cheaper per click and more expensive per qualified lead, because distance, scope and heritage knowledge cut the share of enquiries worth quoting. That is the pattern worth testing, not a rule. For a trade where travel time is a real cost, the Inner West core tends to hold up better than its click price suggests.

Call tracking, lead qualification and quoting speed

For a tradie, the phone is the conversion. Google Ads can count calls from ads as conversions once they reach a minimum call length that you set, so choose a threshold that screens out wrong numbers without cutting real emergencies. Our tracking guide shows how to check that calls, forms and bookings are counted once each.

Then qualify. Typical groups are the tyre-kicker (no scope, no budget), the quote shopper (collecting three quotes with no preference), and the fit lead (clear scope, right suburb, realistic budget). A short form asking for suburb, type of work and rough budget range will reduce the first two groups, though it also reduces total enquiries, so compare cost per signed job, not cost per lead. Speed matters at both ends: an emergency enquiry that waits an hour is gone, and a renovation enquiry that gets a considered reply within a day usually beats a rushed quote a week later. We have no verified Inner West data on response times, so treat this as practice, not evidence.

Worked example: the allowable cost per acquired job

An illustrative Leichhardt renovation builder (not a real business) works backwards from the job, not from the click.

  1. Average job value is $180,000. After direct costs, gross margin is 20%, so gross profit per job is $36,000.
  2. The builder is willing to spend 10% of gross profit on winning a job: $3,600 is the allowable cost per acquired job.
  3. One in four qualified quotes is won (25%), so the allowable cost per qualified lead is $3,600 x 0.25 = $900.
  4. One in three raw enquiries is qualified (about 30%), so the allowable cost per raw enquiry is $900 x 0.30 = $270.

Now test two scenarios against that ceiling.

Illustrative scenarioCost per clickClick to enquiryCost per enquiryCost per qualified lead (30%)Cost per won job (25%)Within $3,600?
A$84%$200$667$2,667Yes
B$143%$467$1,556$6,222No
Illustrative arithmetic: cost per enquiry = cost per click divided by click-to-enquiry rate; per qualified lead divides by 0.30; per won job divides again by 0.25.

Scenario A leaves headroom; scenario B costs 73% more than the builder is willing to pay. Neither is a forecast. The point is that the ceiling is known before the first click, so the decision between a campaign, a better landing page or a narrower suburb list is arithmetic, not mood. If your numbers differ, our guide to how much to spend on marketing shows the same logic for budgets.

Pre-flight checklist and limits

Pre-flight compliance checklist

  • Licensee name, licence number with the correct category of work, and business phone number appear in each ad format.
  • The licence matches the work advertised (building, plumbing, electrical and so on).
  • Any price shown is the single total price, or the total is also clearly stated.
  • No claim about approvals, timelines or results that you cannot substantiate.
  • Deposit and contract statements are consistent with the written contract rules.
  • Reviews are real, not incentivised without disclosure, and negative ones are not removed.
  • A record exists of who placed each ad and where it ran.
  • Service-area settings on your Business Profile are correct. Google's guidance says a service-area business that does not serve customers at its address should hide it.

Limits of this advice

We have not verified penalty amounts for advertising breaches, the detail of each licence class, or current Council fees. We have no verified suburb-level job-size data, and every figure in the worked examples is illustrative. A firm that does mostly referral work may rightly decide that advertising is a small part of its mix. This guide is general information, not legal advice. Check with NSW Fair Trading, Council or a professional before you act.
