8 questions to ask a town planner. And 4 to never ask.

A town planner is one of the most useful professionals a property buyer can engage. They translate council planning rules into your specific lot. They tell you what is possible, what is contested, and what is impossible. A 60-minute pre-purchase consultation can save you tens of thousands of dollars by ruling out unsuitable properties or confirming a viable redevelopment thesis.

But the engagement is hourly. The fees range $250-450 per hour. Productive conversations get value for money. Unproductive ones burn cash quickly.

This post is the eight questions worth asking and the four to skip.

The 8 questions worth asking

Question 1: Is this site eligible for complying development for my intended project?

The complying-development pathway saves time and cost. Your town planner can answer this in 5-10 minutes based on the zone, the lot characteristics, and your project description. If the answer is yes, your project timeline is half what it would otherwise be.

If the answer is no, the next question follows.

Question 2: What is the most likely DA pathway and timeline for my intended project?

If complying development is unavailable, what is the realistic timeline through a full DA? The answer depends on the council's typical assessment times, the project complexity, and the likelihood of objections.

A planner who knows the council can usually estimate within 6-10 weeks of accuracy.

Question 3: What overlays apply that I might have missed?

Heritage, character, flood, bushfire, coastal, biodiversity, easements, infrastructure designations. The planner cross-checks your assumptions against the actual mapping. Often catches one or two overlays you did not know about.

Question 4: What is the realistic build envelope on this lot?

Setbacks, height limits, FSR, site coverage, articulation requirements. The planner can sketch the buildable mass that the planning rules support, accounting for all the constraints together.

This is the answer that tells you whether your intended dwelling actually fits.

Question 5: Are there any pending or recent DAs nearby that affect my application?

Some councils give weight to recent precedents in their assessments. A neighbour's recent successful DA for a similar project strengthens your case. A neighbour's failed application or active objection may complicate yours.

The planner reads the council's DA register and the surrounding neighbourhood context.

Question 6: What objections are likely to arise from my application?

Council, neighbours, heritage authority, environmental groups. The planner knows which objections are routine for the project type and area and which would be unusual.

This question reveals whether your project is straightforward or contested.

Question 7: What is the conservative cost estimate for the planning process?

Architect/drafter, engineer, heritage consultant (if needed), arboricultural report (if needed), DA fees, certifier fees, conditions compliance, planning agreement contributions. The planner can scope these by project type and council.

Most buyers underestimate the total planning cost by 30-50%. The planner's estimate is the realistic budget.

Question 8: If I had to walk away from this site, what would change your mind?

The most useful question many buyers do not ask. The planner has seen the site and the project. If they have reservations, the question gives them permission to share. Sometimes the answer reveals a critical constraint that no other question would surface.

The 4 questions to skip

Question to skip 1: "What do you think this property is worth?"

Town planners do property valuation only incidentally. A registered valuer is the right professional for this question. Asking the planner forces them to either decline (wasted hourly billing) or speculate (potentially misleading).

If you need a valuation, hire a valuer separately.

Question to skip 2: "Is this a good investment?"

"Good" depends on your strategy, your hold period, your risk tolerance, your capital structure, your tax position. The planner has none of this context. They can speak to planning viability but not investment merit.

A buyer's agent or investment property advisor is the right professional. Or your accountant. Or yourself.

Question to skip 3: "Should I bid above the price guide?"

Bidding strategy and price guidance are agent territory, not planner territory. The planner cannot tell you what other buyers are willing to pay or what the auction dynamics will be.

The right professional for this question is a buyer's agent or no professional at all (you decide based on the property's value to you).

Question to skip 4: "Tell me everything about this council and area"

Open-ended questions burn hours of billing without producing actionable answers. The planner will give you broad context that you could have read on the council website yourself.

Replace the open question with specific ones. "What are the council's three most common DA refusal reasons?" gets you actionable insight. "Tell me about the council" gets you 40 minutes of paid summary.

The 60-minute pre-purchase consultation

A typical productive pre-purchase consultation with a town planner:

• Pre-meeting: send the planner the address, the planning certificate, the relevant council documents (10 minutes of your prep time)
• The meeting: 45-60 minutes covering the 8 questions above ($250-450 of professional fees)
• Follow-up: short written confirmation of the key advice ($50-150 of additional billing)

Total cost: $300-600. Total information value: typically equivalent to or greater than the planner's fee.

When to engage a town planner versus rely on your own research

Three situations favour the planner:

Situation 1: substantial redevelopment intent

If your purchase is conditional on knock-down-rebuild, subdivision, dual occupancy, or substantial extension, the planner's confirmation of feasibility is worth the fee.

Situation 2: heritage or character properties

Heritage layers add complexity that is difficult to fully assess from self-research. A planner who works in the heritage area regularly knows the local heritage officer's preferences and the typical assessment outcomes.

Situation 3: properties with hazard overlays

Flood, bushfire, coastal, landslip overlays all add planning complexity that benefits from professional translation.

Three situations where DIY research is sufficient:

DIY 1: buying an existing dwelling to occupy as-is

If you have no intention of redevelopment or substantial alteration, the planning rules are largely informational. The 60-second LEP read and a SafeBuy report give you 90% of what you need.

DIY 2: small renovations within the existing envelope

Internal renovations and minor extensions within the existing dwelling envelope typically do not require deep planning analysis.

DIY 3: lots in straightforward residential zones with no overlays

If the lot is clear of all overlays, in a permissive zone, and matches the suburb's standard housing stock, planning is unlikely to surprise.

The planner's value is then concentrated on the 30 minutes that require professional judgment: project-specific feasibility, council-specific dynamics, objection prediction, design optimisation.

The combination of SafeBuy plus 60 minutes of planner consultation is materially better than either alone. The data and the judgment compound.

Town planners are some of the most underused resources in Australian property due diligence. The 8 questions above turn an hourly consultation into a sharp pre-purchase asset. The 4 to skip stop you from converting the planner into a expensive talk-show host.
