Frequently Asked Questions
Does a granny flat increase property value?
A compliant, certified granny flat commonly adds more than its build cost in high-demand suburbs, but results vary. See do granny flats add value.
Can I claim negative gearing on a granny flat?
If the flat is rented and you borrow to build, interest and eligible expenses can be deductible. Rules differ when the flat sits on your principal residence. Ask a tax agent.
Are studio apartments harder to sell than houses?
Studios can be sensitive to oversupply and lending policy on small apartments. Granny flats are not sold separately; value is realised when you sell the whole property.
Which has lower vacancy risk?
Depends on location. CBD studios near employment hubs fill fast. Granny flats in transport-linked suburbs also rent steadily. Analyse local vacancy data, not national averages.
Can I Airbnb a granny flat instead of a long-term studio lease?
Short-term rental rules vary by council. Long-term tenancy usually gives more predictable cash flow for either asset type.

How much does council approval add to your granny flat budget?
Council and certifier fees sit outside the builder quote. In NSW, a CDC pathway through a private certifier often lands between roughly $3,000 and $8,000 once survey, BASIX and Sydney Water checks are included, while a full DA can cost more because of longer consultant time and holding costs. Victoria and Queensland use different fee schedules, so treat any single number as a starting point.

What design choices affect approval speed?
Setbacks, height, floor area and tree protection overlays decide whether you stay on a fast CDC track or drop to a slower DA. Staying under common 60 sqm internal caps, keeping adequate side and rear setbacks and connecting services without major easement conflicts usually keeps the pathway simpler. If your block is sloped, flood-affected or heritage-listed, expect extra reports before council or your certifier can sign off. Use the setback checker and approval wizard against your address before you pay for custom drawings.
