2026 Granny Flat Regulations on the Gold Coast

Building a granny flat on the Gold Coast is becoming increasingly popular, especially with the rise of multi-generational living and growing demand for flexible, self-contained accommodation.

As we move into 2026, it’s important to understand the rules that apply to secondary dwellings in the Gold Coast region and what you’re legally allowed to do with them. This guide breaks down the key regulations, recent changes, and why using a licensed builder is essential for compliance and peace of mind.

What Counts as a Granny Flat on the Gold Coast?

Under the Gold Coast City Plan, a granny flat is classed as a “Secondary Dwelling.” It’s a self-contained living space built on the same lot as an existing main house and must remain clearly subordinate to the primary dwelling. It can be attached, underneath, or completely separate, depending on your block layout and design goals.

Granny flats typically include a bedroom, bathroom, living area, and kitchen — making them ideal for family members, tenants, or guests.

Key Regulations for Building a Granny Flat in 2026

1. Maximum Size Limits

Most granny flats on the Gold Coast can be up to 80m² of gross floor area. This measurement excludes outdoor areas like patios, verandahs, carports, or decks.

2. One Granny Flat Per Lot

Only one secondary dwelling is allowed per residential lot, and it must remain smaller than and secondary to the main home.

3. Location on the Property

Granny flats generally need to be within 10 metres of the main dwelling, though some rural or larger lots may allow slightly more flexibility.

4. Shared Services

Your granny flat must connect to the same water, sewer, electricity, and driveway access as the main house. These connections must meet building and plumbing codes.

5. Parking Requirements

Most designs must include at least one additional parking space, separate from the main house parking.

6. Building Approvals Are Mandatory

Every granny flat requires building approval through a licensed certifier. This ensures the construction meets structural, fire safety, insulation, and energy efficiency standards.

7. Development Approval

Some granny flats qualify for “accepted development,” meaning you may not need a full Development Application if your design meets all zoning, setback, and overlay requirements.

However, if your block has overlays such as flood, bushfire, vegetation, character, or environmental protections, a Development Approval may be necessary.

Recent Changes Affecting Gold Coast Granny Flats

In recent years, Queensland introduced new rules allowing granny flats to be rented to anyone, not just family members. This significantly increases their investment potential and makes them a strong option for generating passive income.

However, renting to non-household members requires the granny flat to meet all building code requirements for fire separation, soundproofing, and independent living safety standards. Older flats built under previous rules may require updates before being legally rented out.

What You Can Use a Granny Flat For

A granny flat on the Gold Coast offers exceptional flexibility. In 2026, approved uses include:

• Long-term rental income
• Housing for parents, adult children, or extended family
• Guest accommodation
• A teenager’s retreat
• A separate home office or studio
• Short-term accommodation (depending on council rules and approvals)
• A private retreat while still staying close to home

Because they are fully self-contained, granny flats add genuine livability and long-term value to your property.

Why You Should Use a Licensed Builder

Building a granny flat is more than just putting up an extra room — it is a fully regulated construction project that must comply with strict planning rules, building codes, and safety requirements.

Working with a licensed and insured Gold Coast builder eliminates the risks and ensures your project is delivered correctly from start to finish.

A licensed builder will:

• Ensure your design complies with the Gold Coast City Plan
• Manage all building approvals and work with certifiers
• Ensure the correct setbacks, height limits, and site coverage rules are met
• Coordinate trades and construction safely and professionally
• Handle plumbing, electrical, foundations, and structural requirements correctly
• Ensure fire safety, sound insulation, and energy compliance standards are achieved
• Provide insurance protection for the duration of the build
• Deliver a high-quality finished dwelling that passes final inspection

Using an unlicensed builder risks non-compliance, fines, failed approvals, insurance problems, or even council-issued demolition orders. A licensed builder protects your investment, ensures structural integrity, and guarantees your granny flat is built legally and safely.

Before You Start Building: Key Things to Check

• Zoning and overlays on your property
• Available space for the dwelling and parking
• Compliance with size, height, and setback requirements
• Service connections (water, sewer, electricity)
• Access to the site
• Bushfire, flood, or ecological constraints
• Whether a Development Application is required

A builder familiar with Gold Coast regulations can handle this entire process for you, making your project smooth, compliant, and stress-free.

Conclusion

Granny flats remain one of the most valuable additions you can make to a Gold Coast property. With updated regulations, flexible usage options, and rising demand for self-contained living, they offer both lifestyle benefits and strong financial returns.

As you plan your 2026 granny flat project, choosing a fully licensed and insured Gold Coast builder is the best way to ensure your dwelling is designed, approved, and constructed to the highest standards — giving you peace of mind and protecting your investment for years to come.
