Project GuidesGranny Flat Rules QLD 2026 — Approval Guide for Queensland
Queensland granny flat approval guide for 2026 — covering accepted development vs DA, 80m² size limit, rental rules since Sep 2022, and council-specific requirements.
Overview
Queensland's granny flat rules changed significantly in September 2022 when rental restrictions were removed. Homeowners can now rent secondary dwellings to anyone, not just family members. The approval process varies by council, with many allowing granny flats as accepted development — no DA required.
Approval Pathways
Accepted Development — No DA Required
Many Queensland councils allow secondary dwellings as "accepted development" if they meet specific criteria. This means no formal Development Application is needed — only a building approval.
You may avoid a DA if:
- The granny flat is within council size limits (often ≤ 80m²)
- It's within 20m of the primary dwelling
- The lot meets minimum size requirements (often 450–600m²)
- No special overlays apply (flood, bushfire, character, biodiversity)
Development Application — Council Assessment
A DA is required if the project exceeds accepted development thresholds.
You'll likely need a DA if:
- Internal floor area exceeds council limits (often 80m²)
- The structure is more than 20m from the main house
- The lot is affected by overlays
- The lot is smaller than the council's minimum
Building Approval — Always Required
Regardless of whether a DA is needed, all secondary dwellings in QLD require building approval from a licensed private building certifier to comply with the National Construction Code.

Rental Rules
Since September 2022, homeowners can rent granny flats to anyone — no family connection required. This change was introduced via planning regulation amendment and applies statewide.
Note: The rental restriction removal was implemented with a three-year review period, placing a review point around late 2025. As of March 2026, the change remains in effect.
Key Council Variations
Queensland does not have a single statewide CDC-style pathway like NSW. Rules vary by council:
| Council Area | Typical Max Size | Notes |
|---|---|---|
| Brisbane City | 80m² | Check BCC planning scheme |
| Gold Coast | 80m² | Overlay-dependent |
| Sunshine Coast | 80m² | Check local planning scheme |
| Ipswich | Varies | Contact council |
| Townsville | Varies | Contact council |
Always check your specific council's planning scheme for the exact requirements that apply to your property.
