Granny flat enquiries often fail to go ahead because the project dies at one of six checkpoints: site eligibility, finance and valuation, siteworks the base price left out, the approval wait, an unsettled rent-or-family decision, or a quote that expired. On this page’s middle-band assumptions only about 10 in 100 enquiries reach a signed build, and finance and site rules remove 55 of the 100 before a quote is worth writing.
The short answer from LeadsNow AI: Granny flat enquiries that do not proceed have often stalled on lot size, finance or a siteworks price shock rather than on a competitor, so LeadsNow recommends asking one screening question per checkpoint at the first call and tagging every dead enquiry with the checkpoint it stalled at. On this page’s middle-band assumptions, lifting the share of quoted clients who sign before the quote lapses from 55% to 70% adds about 2.7 signed granny flats per 100 enquiries without one extra lead.

At a glance
- The asset: the Granny Flat Enquiry Drop-Off Map, six checkpoints each with the question to ask at the first call and the reactivation message for that stall, plus a worked 100-enquiry funnel.
- The metric: enquiry-to-signed rate = signed granny flat contracts ÷ enquiries received, over 90 days, split by the checkpoint each lost enquiry stalled at.
- The benchmark: none public. We found no credible published enquiry-to-contract rate for Australian granny flat builders, so every pass rate here is a labelled assumption to replace with your own count.
- Not covered here: what a lead costs (granny flat lead costs in Australia), where leads come from (lead generation for granny flat builders) and the full dead-quote sequence (how to reactivate dead quotes).
Rules of thumb
- Ask lot size before anything else in NSW: a secondary dwelling on a lot under 450 m² cannot be approved as complying development, though a development application may still be possible (NSW Planning, secondary dwellings FAQ).
- Quote the all-in number, not the base build: What’s The Damage puts site works and service connections at $15,000 to $40,000 and driveway, path and basic landscaping at $5,000 to $20,000 on top of a turnkey contract (WTD granny flat cost guide, November 2026).
- Re-check any quote older than a quarter: the ABS input to house construction price index rose 1.0% in the September quarter 2026 and 3.9% over twelve months (ABS Producer Price Indexes, September 2026).
- In the middle band, finance (30 lost) and site eligibility (25 lost) remove 55 of every 100 enquiries, so screen for both on the first call before booking a site visit.
Why do granny flat enquiries not go ahead? The Granny Flat Enquiry Drop-Off Map
Granny flat enquiries stall at six checkpoints, and the Granny Flat Enquiry Drop-Off Map pairs each with a first-call question that exposes it and a message that reopens it later. The order follows the homeowner’s path from enquiry to contract, not frequency, because no public data ranks these causes.
| Checkpoint | What stalls it | Question to ask at the first call | Reactivation message for that stall |
|---|---|---|---|
| 1. Site eligibility (NSW complying development vs DA) | Lot under 450 m², width, overlays or a floor-area cap that counts the main house too | “Roughly how big is your block, and do you know of any flood, bushfire or heritage overlay on it?” | “We have looked at blocks like yours that missed complying development. Want us to check whether a DA route works for your lot?” |
| 2. Finance and valuation | No construction loan pre-approval, or equity lower than the homeowner assumed | “Are you funding this from savings, a construction loan or equity, and has a lender looked at it yet?” | “Has your finance position changed since we last spoke? We can re-send the quote in the format your lender asks for.” |
| 3. Siteworks and services exclusions | Base price excluded site works, connections, driveway or approvals | “Has anyone given you an all-in number including site works, connections and approvals?” | “We have rebuilt your quote as one all-in figure so nothing is left to surprise you. Want a copy?” |
| 4. Approval timeline | DA wait longer than the homeowner planned for | “When do you need the flat finished, and is that date fixed?” | “Your approval timing may look different now. Shall we map the dates from approval to handover again?” |
| 5. Rental vs family use | Household undecided between a rental and a home for a parent or adult child, or local use rules | “Who is the flat for: family, a tenant, or both over time?” | “Has the plan for who lives in the flat settled? The layout we would suggest differs for each.” |
| 6. Quote expiry | Quote lapsed while the homeowner waited, and the repriced number feels like a new deal | “If the numbers work, when would you want to sign?” | “Your quote has expired. We have re-checked current material costs: do you want the refreshed figure?” |
The first-call questions screen rather than sell: an enquiry failing checkpoint 1 or 2 is a nurture contact, not a site visit.

FAQ: granny flat enquiries that do not go ahead
Is a granny flat enquiry on a block under 450 m² a dead lead?
No. In NSW a lot under 450 m² cannot use complying development for a secondary dwelling, attached or detached, unless it sits entirely within the existing house, but NSW Planning’s secondary dwellings page says a development application to council may still be possible. Treat it as a slower project and say so on the first call.
How long should a granny flat quote stay valid?
Set the validity period yourself and print it on the quote. With the ABS input to house construction index up 3.9% over the year to September 2026, a quote held for six months or more is worth re-checking before the client signs.
Why do granny flat clients go quiet after receiving the quote?
Granny flat clients often go quiet after a quote because the all-in cost is higher than the base price they anchored on, or finance is not yet approved. Site works, connections, driveway and approvals can add tens of thousands of dollars, so ask which checkpoint stalled them before re-sending anything.
How many granny flat enquiries should become signed contracts?
No public benchmark exists for Australian granny flat builders. This page’s worked funnel uses assumption bands: about 3 signed per 100 enquiries in the leaky band, 10 in the middle band and 27 in the tight band. Replace each pass rate with your own 90-day count.
Should I visit the site before the client has finance approval?
Visit only if the lot passes the eligibility question and the client can say how the build will be funded. In the middle band, finance removes 30 of every 100 enquiries, so a visit before that answer is often a visit to a project that cannot proceed yet.

How many granny flat enquiries should end in a signed build?
About 10 in every 100 granny flat enquiries reach a signed contract in this page’s middle band, against roughly 3 in the leaky band and 27 in the tight band. Every pass rate is an assumption for illustration; we found no published Australian enquiry-to-contract rate for granny flat builders.
| Checkpoint (pass rate, assumptions) | Leaky band | Middle band | Tight band |
|---|---|---|---|
| Enquiries received | 100 | 100 | 100 |
| 1. Site eligible (60% / 75% / 85%) | 60.0 | 75.0 | 85.0 |
| 2. Finance confirmed (50% / 60% / 75%) | 30.0 | 45.0 | 63.8 |
| 3. Accepts all-in price incl. siteworks (40% / 55% / 70%) | 12.0 | 24.8 | 44.6 |
| 4. Accepts approval timeline (70% / 80% / 90%) | 8.4 | 19.8 | 40.2 |
| 5. Use decided (80% / 90% / 95%) | 6.7 | 17.8 | 38.2 |
| 6. Signs before the quote expires (40% / 55% / 70%) | 2.7 | 9.8 | 26.7 |
Reading the middle column, enquiries lost at each checkpoint are 25, 30, 20.3, 5.0, 2.0 and 8.0. Lifting checkpoint 6 from 55% to 70% turns 17.8 decided households into 12.5 signed builds instead of 9.8, a gain of 2.7 per 100 enquiries. At the roughly $175,000 What’s The Damage gives for most two-bedroom builds, that is about $470,000 of contract value per 100 enquiries, from follow-up alone.

Which checkpoint is losing your granny flat enquiries, and how do you test it?
The checkpoint losing your granny flat enquiries is the one whose 90-day pass rate sits furthest below the middle band, and a CRM export plus one tag per lost enquiry finds it in an afternoon.
- Export every granny flat enquiry from the last 90 days.
- Tag each lost or silent enquiry with the first checkpoint it failed. If nobody asked, tag it “unknown”: that count is itself the finding.
- Divide the enquiries that passed each checkpoint by the ones that reached it, compare with the middle band, and fix the lowest first.
If more than a third of lost enquiries are “unknown”, the leak is the first call itself, and speed to lead for trade businesses is the place to start. To connect each tag to revenue, track which leads become booked jobs.
Why does site eligibility stop so many granny flat enquiries in NSW?
Site eligibility stops NSW granny flat enquiries because complying development, the fast approval route, requires a lot of at least 450 m² and a floor area that counts the main house and attached structures. NSW Planning’s secondary dwellings page says a lot under 450 m² cannot use complying development unless the secondary dwelling sits entirely within an existing house, though a development application to council may still be possible.
- Floor area: the same page says the maximum floor area includes the principal dwelling, the secondary dwelling and any attached carport, garage, deck, patio, pergola or verandah, so a large existing house can sink a block that looks big enough.
- Timeline: NSW Planning’s complying development page says fast-tracked approvals can be issued in as little as 20 days, against an average determination time of 70 days for a development application. That gap is checkpoint 4 in miniature.
- Outside NSW: rules are set by state and council. A 2021 Sunshine Coast News report described a then town plan requiring a 600 m² block and a granny flat within 20 m of the main dwelling, and quoted a builder whose first enquiry question was about that 20 m rule. Check the current local plan.

Why do siteworks and expired quotes kill granny flat deals after the quote?
Siteworks and expired quotes kill granny flat deals because both move the price after the homeowner has anchored on a number. What’s The Damage’s November 2026 granny flat cost guide lists site works and service connections at $15,000 to $40,000 (typically $25,000) and approvals at $3,000 to $12,000, and advises confirming what is excluded because those items are often quoted separately.
On a $175,000 build, the typical $25,000 of site works and connections plus $10,000 for driveway, path and basic landscaping adds $35,000, or 20%, to the anchored figure. A homeowner who budgeted the base price often goes quiet rather than name the gap.
Quote expiry compounds it. The ABS input to house construction index rose 1.0% in the September quarter 2026 and 3.9% over the year, led by plumbing products and electrical equipment. That index tracks builders’ input costs, not quote prices, but explains why a quote repriced after six months feels like a new deal.
Which stalled granny flat enquiries are worth reactivating?
Stalled granny flat enquiries worth reactivating are the ones tagged at checkpoints 2, 4, 5 and 6, because finance, timing, household plans and expired prices all change on their own while the site stays the same.
- Reactivate first: checkpoint 6 (quote expired) and checkpoint 2 (finance). These households had a priced, eligible project.
- Reactivate with new information: checkpoint 3 (siteworks shock) only with an all-in figure, and checkpoint 1 only with a DA option for that lot.
- Leave alone: clear noes and anyone who asked not to be contacted.
The consent, unsubscribe and Do Not Call Register rules for re-contacting old quotes are set out in how to reactivate dead quotes, and the wider method is on the database reactivation page. Doing it yourself costs a CRM export, an afternoon of tagging and someone free to answer replies the same day. The same stall pattern after a design is paid for shows up in landscape design clients not proceeding to build.
