A secondary dwelling—commonly called a granny flat—is a self-contained dwelling established in conjunction with a principal dwelling on the same lot. It can be within, attached to or separate from the principal dwelling. Its legal classification depends on the approved proposal and documents, not its appearance or marketing description. The NSW Government’s secondary-dwelling guidance explains this statewide framework.
This guide combines the few verified statistical facts available for Galore with statewide planning, construction and tenancy guidance. It cannot establish what applies to a particular property. The address, legal parcel, responsible council, zoning, local planning instruments, title restrictions, services and relevant mapped controls must all be checked before a project is described as suitable.

Local granny-flat overview
Galore is recorded as Australian Bureau of Statistics Suburbs and Localities geography, or SAL, code 11585. SAL boundaries are statistical approximations used for Census and other data; they are not cadastral boundaries, planning zones or council boundaries. SAL must not be confused with Statistical Area Level 1 or SA1. The canonical locality record covers approximately 259.0241 square kilometres and five mesh blocks, but neither figure says anything about the development capacity of an individual parcel.
The same record shows Galore intersecting the ABS statistical LGAs named Wagga Wagga and Narrandera, with Wagga Wagga having the larger overlap by area. This is statistical context only. It does not prove which council administers an address or which planning instrument applies. The ABS LGA name “Wagga Wagga” is also distinct from the formal organisation name “Wagga Wagga City Council”. Owners must identify the legal parcel from its address and lot/deposited plan, use current official mapping and confirm the responsible authority directly. A parcel in the Narrandera overlap cannot be assigned an authority by assuming the dominant overlap controls the whole locality.
The 2021 Census Galore QuickStats reported 70 people, 17 families and 24 private dwellings. These are historical 2021 Census values for the statistical locality, not current population or property-market evidence. The very small population and dwelling counts also make broad demographic, rental-demand or market conclusions unsafe: a small number of households can materially affect percentages and medians, while the SAL boundary may not correspond with a reader’s legal parcel.
At the property level, the starting questions are whether a lawful principal dwelling exists, which zone applies and whether the relevant planning instrument permits a secondary dwelling. State guidance says secondary dwellings are permitted in residential zones R1, R2, R3, R4 and R5 and may be permitted in other zones by the applicable local environmental plan. That is a statement of possible permissibility, not approval. Rural and non-residential land requires direct examination of the local environmental plan because some instruments contain specific rural-zone provisions.
The principal and secondary dwellings remain on the same lot under this framework. The secondary-dwelling pathway does not create a separately subdividable, separately titled or independently saleable residence. An existing garage, shed or studio is not lawful accommodation merely because it can physically be converted. Its approval history, proposed change of use, building work and certification requirements must first be established.
Council rules and approval pathway
A secondary dwelling may proceed through a development application assessed by the responsible council or through complying development if every applicable requirement is satisfied. Under the first pathway, council assesses the proposal against current environmental planning instruments, relevant local controls and site impacts. Under the second, council or an appropriately registered certifier may issue a complying development certificate. A certifier applies the rules; the certifier cannot waive an exclusion or development standard.
For the Housing SEPP complying-development pathway, NSW guidance identifies a lot area of at least 450 square metres, except where the secondary dwelling is located entirely within an existing dwelling house. This is one bounded eligibility test only. It is not a universal minimum for a council-assessed application and does not establish complying-development eligibility by itself.
The current State Environmental Planning Policy (Housing) 2021, including Schedule 1, and the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 must be read with the property’s zone, mapped exclusions and applicable local instruments. The Department’s complying-development guidance explains the standards-based pathway and the role of the certifier.
The Housing SEPP includes site and floor-area controls, but no universal floor area, setback, height, landscaping or site-coverage figure should be taken from an old guide or another development type. The applicable controls depend on the current instrument, property and pathway. State guidance says the Housing SEPP does not itself require additional parking for a secondary dwelling; nevertheless, loss of existing approved parking, driveway design, legal access, vehicle crossings and existing consent conditions may remain relevant.
Before selecting a pathway, verify:
- the address, lot/deposited plan, title arrangement and lawful principal dwelling;
- zoning and the current local environmental plan, development control plan and any site-specific instrument;
- easements, covenants, restrictions, sewer and drainage assets, utilities and legal access;
- mapped controls or exclusions actually affecting the parcel;
- whether the proposal is internal, attached, separate or a conversion; and
- council submission requirements, contributions, waste arrangements, stormwater policy and servicing requirements.
The NSW Planning Portal Spatial Viewer is the official starting point for address and parcel mapping. Its results should be checked against the current legal instruments, title, survey and approval history. Planning approval may not displace private title restrictions, and a concept plan, quote, BASIX certificate or builder’s statement is not development approval.
After approval, the project may require construction certification, inspections and evidence that approval conditions have been met. Service NSW explains that an occupation certificate is required before occupying or using a new building or changing an existing building’s use. Confirm the required documentation and inspection stages with the appointed certifier before work begins.
Costs and budgeting
No verified Galore construction rate, council fee, contribution or utility allowance is available in the supplied evidence. Build the budget from the investigated site and documented scope rather than an advertised package or suburb-wide estimate. Obtain itemised, like-for-like quotes based on the same survey, drawings, specification, reports and approval assumptions.
Allow separate headings for:
- title searches, surveys, service location and preliminary investigations;
- design, engineering and specialist consultants;
- application, Planning Portal, council and certifier charges;
- contributions where an applicable plan requires them;
- demolition, excavation, retaining and site preparation;
- building work, fixtures, finishes and BASIX commitments;
- water, sewer, electricity, telecommunications and stormwater work;
- access, paths, fencing, landscaping and other external works; and
- insurance, inspections, certificates and handover documentation.
Cost sensitivity comes from the actual property. Access restrictions, slope, ground conditions, service distances, existing structures, drainage, required reports and finish selections can alter the scope. A conversion may require structural work, waterproofing, insulation, fire-safety measures, ventilation and service upgrades, so an existing shell should not automatically be treated as a low-cost solution. Resolve uncertainties early and retain an allowance suited to the risks that remain, rather than applying an unsupported standard percentage.
Require each quote to identify inclusions, exclusions, provisional sums, prime-cost items and responsibility for approvals, BASIX, engineering, authority applications, inspections and final certificates. Check current charges with the relevant authority for the defined proposal.
Building Commission NSW contract guidance states that residential building work costing more than $5,000 requires a written contract, work costing more than $20,000 requires the more extensive large-job contract, and the maximum deposit is 10%. Read the Consumer Building Guide and align progress payments with completed work.
Home building compensation cover is required in applicable circumstances for residential building work valued at $20,000 or more, including GST. Obtain the project-specific certificate before paying where cover is required and verify it through the official HBC Check. Recheck the current contract and insurance rules when procuring the work.
Design and site considerations
Begin design with verified parcel information, a survey and a plausible approval pathway. Consider how the secondary dwelling relates to the principal dwelling, including access, privacy, overlooking, daylight, ventilation, noise, private outdoor space, waste storage, clothes drying and maintenance. A standard plan that fits geometrically may still conflict with planning controls, services or the amenity of either dwelling.
Check the relevant controls for building position, floor area, height, landscaped area, site coverage and earthworks against the current instruments identified for the parcel. For a development application, the responsible council may require additional plans or reports addressing local controls and impacts. For complying development, every applicable standard and exclusion must be tested before the design is treated as eligible.
Locate sewer, drainage, water, electricity and telecommunications infrastructure early. Confirm lawful connection points, system capacity, easements and authority protection requirements. Stormwater needs a lawful property-specific solution. If on-site wastewater is involved, investigate the existing approval, capacity and land-application requirements rather than assuming another dwelling can connect.
Address constraints only when official mapping or property investigations indicate relevance. Potentially relevant matters can include bushfire, flooding, heritage, biodiversity, contamination, acid sulfate soils, coastal hazards or mine subsidence, but the Galore SAL record proves none of them for an address. Use the Spatial Viewer as an initial check, then obtain the reports required for the actual mapped issue. A title search and survey remain necessary because planning maps may not show private restrictions, accurate boundaries or encroachments.
BASIX should inform concept design rather than being added after key decisions. The Planning Portal BASIX guidance covers water, energy use and thermal performance. Its secondary-dwelling project guidance distinguishes conversions, new attached or separate work, and projects involving new principal and secondary dwellings together. Select the project type that matches the approved scope and carry its commitments into specifications, construction and certification.
Prefabricated, modular or relocatable construction does not bypass planning, building, BASIX or certification requirements. Likewise, converting an outbuilding requires investigation of its lawful existing use and the approvals needed for habitation.
Rental and investment considerations
Assess rental use only after confirming lawful approval and the steps required for occupation certification. Retain approvals, stamped plans, inspection records, certificates and warranties because they may be relevant to leasing, insurance, maintenance and future property transactions.
If the completed secondary dwelling is rented under a residential tenancy, current NSW Fair Trading residential-tenancy guidance applies alongside the Residential Tenancies Act 2010. Use the current standard agreement and follow the applicable processes for required information, condition reporting, bonds, repairs, safety, access and ending a tenancy.
Do not assume that family occupation, room letting, a licence, short-stay accommodation and a standard residential tenancy have identical legal or planning treatment. Obtain advice for the intended arrangement and check whether the approval contains relevant conditions.
Plan practical arrangements between the two dwellings. Consider private access, mail, waste storage, outdoor areas, utility supply, charging arrangements and responsibility for shared services or grounds. Separate metering may suit some projects, but feasibility, authority requirements and tenancy rules need to be checked before it is specified.
The small 2021 Census dataset is not evidence of current achievable rent, vacancy, demand or investment performance. Use recent comparable evidence appropriate to the completed dwelling and distinguish advertised asking prices from completed transactions. Seek advice suited to the owner’s circumstances about finance, insurance, taxation, legal obligations and property management. A feasibility assessment should account for the full approved project scope, ongoing maintenance and periods without rental income rather than relying on the building quote alone.
Choosing a granny-flat builder
Undertake preliminary planning and site investigations before requesting final tenders so builders price a consistent, realistic scope. Identify the legal entity that would enter the contract and use the official builder and tradesperson licence check to verify its current licence, category and conditions. An ABN, association membership, advertisement or online review is not a substitute for a valid licence check.
Ask for recent references involving comparable secondary dwellings, approval pathways, access conditions and service work. Inspect completed projects where possible and ask previous clients about communication, variations, site management, defect rectification and handover. References complement rather than replace official checks.
Give tenderers the same drawings, survey, specification, consultant information and known approval conditions. Compare:
- the contracting entity and licensed supervisor;
- inclusions, exclusions, provisional sums and prime-cost items;
- excavation, retaining, access and spoil-removal assumptions;
- service connections, stormwater and external works;
- responsibility for approvals, BASIX, engineering and certification;
- how BASIX commitments appear in the specification;
- variation procedures and extension-of-time provisions;
- progress-payment stages, defects and handover requirements; and
- occupation-certificate documents, product warranties and applicable statutory warranty information.
Use the appropriate written contract, read the Consumer Building Guide and ensure verbal representations are recorded in the agreement. Do not sign a document with blank sections. Have variations documented and priced in accordance with the contract before the varied work proceeds, except where urgent legal or safety circumstances require another process.
Where home building compensation cover applies, obtain the project-specific certificate and verify it before making a payment. Keep approvals, contracts, variations, invoices, inspection records and correspondence. Before final payment, inspect the work, record outstanding defects and collect certificates, manuals, warranties and other handover documents. Obtain independent legal, building or quantity-surveying advice where the scope or risk allocation is unclear.
