What changes the price on your job
The ranges above are the starting point. These five factors are what move a quote up or down within (or sometimes outside) those bands.
- Size — sqm is the biggest single driver of cost.
- Spec — basic vs premium finishes is a $50–$100k spread.
- Site work — flat block with services nearby cheapest; sloping rear-of-block with no services adds $25–$50k.
- Council jurisdiction — some councils make granny flats easy (NSW SEPP exempt-and-complying), others require full DA.
- Demolition + site clearance — old structures, mature trees, contaminated soil add.
Red flags — what to watch for in quotes
We see these patterns every week from operators we'd never recommend. If a quote you've received contains one of these, ask before signing.
- Quotes without site survey + soil test — $25k of ambush costs after deposit.
- Quotes without council permit cost — $3,500–$8,500 on top.
- Builders without HBCF / DBI insurance — illegal in most states over the threshold.
- Cheap-end '$80k granny flat' specials — usually 25sqm studio, no services, no permit.
- Quotes that don't separate services connection — often the surprise cost.
