Building under Cessnock Council Granny Flat Regulations? Here’s What You Need to Know
From Aberdare to Bellbird, Kurri Kurri to Kitchener, more Hunter Valley homeowners are turning to granny flats as a smart way to add space, value, and independence to their blocks. If you’re considering a granny flat in the Cessnock local government area (LGA), here’s what you need to know about what’s allowed, how approvals work, and whether you may be eligible to build something larger than the standard 60m².
What Is a Granny Flat (or Secondary Dwelling)?
In Cessnock and across NSW, a granny flat is officially known as a secondary dwelling. It’s a self-contained home on the same lot as an existing dwelling, and can be either detached, attached, or within the main home.
Granny flats must:
Be located on a property with an existing dwelling house
Use the same lot and title (not subdivided)
Have their own kitchen, bathroom, and living/sleeping area
Share utility connections with the main house
How Big Can a Granny Flat Be in Cessnock?
In most residential zones across NSW, the maximum size for a secondary dwelling is 60m², as specified under the NSW Housing SEPP.
However, in rural zones within Cessnock LGA, it may be possible to build larger than 60m², subject to certain conditions.
Can I Build Larger Than 60m² in Cessnock?
Yes — under the NSW Regional Housing Code, secondary dwellings larger than 60m² can be approved as Complying Development (CDC) on certain rural-zoned properties. Review this case study in Quorrobolong.
According to Cessnock City Council and the NSW Planning Portal, this applies to lots zoned:
RU1 – Primary Production
RU2 – Rural Landscape
RU4 – Primary Production Small Lots
R5 – Large Lot Residential
To qualify:
Your lot must meet the minimum lot size in the Cessnock LEP
The secondary dwelling must be clearly secondary to the main home
Adequate access to water and sewer must be demonstrated (onsite systems may be required in unsewered areas)
All setbacks, bushfire, and flooding requirements must be met
Because many properties in the Cessnock region are semi-rural or rural residential, this pathway is more common than you might expect.
There are two main approval pathways in the Cessnock LGA:
1. Complying Development Certificate (CDC)
A CDC is a fast-tracked approval issued by a private certifier, typically granted within 20 days. You may be eligible if your site complies with all planning and building controls under the NSW Housing SEPP or Regional Housing Code (for rural zones).
2. Development Application (DA)
If your site doesn’t qualify for CDC (e.g. due to bushfire risk, flood zones, sewer issues, or variations from planning controls), you can apply for a DA via Cessnock City Council. This process takes longer and requires a more detailed submission, but may provide more flexibility. Acrow take care of this for you.
Not all properties in the Cessnock LGA are connected to town sewer. For unsewered sites, you’ll need to provide an Onsite Sewage Management System (OSMS) that meets Council and NSW Health guidelines.

When our Client approached Acrow, he had a clear vision: a full-sized granny flat that looked and felt like a real home—with its own garage. The starting point was The Trinity, a popular 3-bedroom design from Acrow’s collection, but a few key tweaks were made to bring it all together.
Now complete in Muswellbrook, this project shows how clients can achieve both comfort and practicality—while staying cost-conscious.
The Design: The Trinity – Modified
The Trinity is one of Acrow’s most spacious layouts, offering three bedrooms, open-plan living, and a full kitchen and bathroom. For Silva’s home, the design was modified to include a garage, a feature not often seen in standard granny flats.
To make it work:
The front door was relocated to the opposite side of the living area
This allowed space to attach a single garage with a panel lift door
Entry is still welcoming, with a Merbau timber deck and stairs at the porch
Despite the addition, Silva stuck to Acrow’s standard inclusions, avoiding unnecessary extras to keep the build efficient and on budget.
Garages and carports can be added to almost any Acrow granny flat—just ask for it to be costed at the design stage.
SOG Construction and Smart Planning
The home was built on a slab-on-ground (SOG) with a drop edge beam, perfectly suited to the site’s fall and soil profile. A timber frame and truss system keeps the construction lightweight and adaptable.
Construction began on 6 December 2024 and reached Practical Completion by 6 June 2025. That’s a 22-week build period, including delays for the Christmas break and extensions of time (EOTs)—well within expectations for a 3-bedroom dwelling with a garage.
Plumbing Performance Solution: A Custom Approach
As part of the planning process, Acrow coordinated a plumbing performance solution to meet local site and drainage conditions. This was developed by engineering consultants to comply with Muswellbrook Council requirements and the National Construction Code, ensuring water runoff and subsurface drainage were properly managed for a long-term, low-maintenance outcome.
From grading the ground away from the footings to sleeving pipes under the slab and using clay backfill to reduce moisture ingress, every detail was covered by the engineering team before construction began.
BAL 12.5 Bushfire Compliance
The property is located in a BAL 12.5 bushfire zone, meaning the build required:
Compliant glazing to windows and doors
Sealed ember-proof construction methods
Fire-rated materials and finishes
These measures were implemented seamlessly without compromising on design or budget.
Client Review: Thoughtful, Cost-Effective Service
Here’s what Silva had to say in his 5-star Google review:
“Acrow Granny Flat had designed a beautiful granny flat at my property in Muswellbrook. Special thanks goes to Acrow Granny Flats sales manager Mick Springs for his exceptional and outstanding customer service, going above and beyond to help the client out and for his smart thinking on how to get the most cost effective solution for the clients. I would also like to thank Crystal, Dario and rest of the team for their support in building this beautiful Granny Flat.”
Silva’s review speaks volumes about the team’s approach. Whether it’s finding practical solutions, meeting bushfire requirements, or adapting designs to suit the land, Acrow focuses on cost-effective outcomes that don’t cut corners.

For time-poor landlords and property investors, granny flats offer a powerful way to maximise income on existing land. This recently completed two-bedroom granny flat in Metford, built under Maitland City Council via the CDC pathway, is a prime example—delivering an estimated $26k per year in additional income (based on current median rent of $500/week, source: domain.com.au, June 2025).
Built for Investment: Trusted by Buyer’s Agents
This project was commissioned by a buyer’s agent acting on behalf of investors who were building a portfolio and needed high-return secondary dwellings without the hassle.
From design and colours to quoting and construction, Acrow worked primarily with the agent to deliver a turnkey result—with minimal input needed from the owners.
Many buyer’s agents recommend Acrow for our combination of cost-effective builds, fast CDC approvals, and a track record of delivering quality outcomes that suit investment budgets.
The Design: The Dock – Kept Simple and Effective
This granny flat follows the standard Dock layout—a compact two-bedroom home designed for efficient construction, practical living, and broad tenant appeal.
The owners selected standard inclusions throughout, proving you don’t need to upgrade everything to get a high-performing rental. Key features include:
Open-plan kitchen, dining, and living area
Functional bathroom with modern fittings
Built-in wardrobes to both bedrooms
Neutral, low-maintenance finishes ideal for tenants
With its simple, proven layout and no-frills inclusions, the flat ticks every box for long-term rental durability.
Construction: Fast, Reliable, and CDC-Approved
The build was completed in 2024 under a Complying Development Certificate (CDC)—meaning no lengthy council DA process. That’s ideal for investors focused on return timelines.
Built on a slab-on-ground with a steel frame and truss system, the structure is solid, fast to assemble, and suited to long-term investment properties where reliability and low maintenance matter most.
Estimated Rental Income: Up to $26k Per Year
Based on the current median rent of $500/week for 2-bedroom homes in Metford and East Maitland, this secondary dwelling is expected to generate over $26,000 in yearly income—on top of the existing rent from the main home.
Whether used to boost yield or improve cash flow on a negatively geared property, granny flats like this one are one of the smartest add-ons available in today’s market.

In NSW, most granny flats are capped at 60m² under Complying Development, but this project in Quorrobolong proves there are ways to go bigger—if your land and zoning allow it. For Sally and Ben, that meant working with Acrow to create an 83.8m² standalone home for Sally’s parents, Barbara and John, right on their own rural property.
It’s a perfect example of how thoughtful planning, flexible design and smart navigation of the DA process can create real housing solutions for families—especially in regions like the Hunter Valley.
The Design: Spacious, Self-Contained and Custom
Approved via Development Application with Cessnock City Council, this custom design includes:
Two generous bedrooms with carpet and dual roller blinds
Ensuite and main bathroom, both upgraded with wall-hung vanities, vessel basin mixers, sleek shaving cabinets and Axon feature wall cladding
Open-plan living and kitchen area, with plenty of natural light
A well-appointed kitchen with gas cooktop, dishwasher, microwave provision with drawer, Polytec “Whitewood” overhead cupboards, and Evostone benchtops in “Typhoon”
A striking feature entrance door with sidelights and merbau timber porch
It’s a comfortable, high-quality home—designed to feel more like a rural cottage than a typical granny flat.
Built on Bearers and Joists to Meet Flood Zone Requirements
The site falls within a flood zone, so the build was constructed on bearers and joists—lifting the home to meet elevation and subfloor ventilation requirements. This solution, along with a steel frame and truss system, ensures durability, compliance and long-term performance.
Bushfire Protection: Compliant with BAL 29
Located in a bushfire-prone area, the dwelling was designed to comply with BAL 29, which required:
Aluminium flyscreens and metal ember guards
5mm glazing to windows and 6mm to sliding doors
10,000L water tank with a firefighting outlet
James Hardie Plank cladding and fire-rated roofing materials
Metal external pipes and fittings, sealed LED lighting and appropriate setbacks
These features aren’t just about compliance—they offer real peace of mind for the residents.
Energy Efficient and Comfortable Year-Round
As part of the BASIX commitments, the home includes:
Zoned air conditioning (5kW in the living area and separate system in the bedrooms)
Electric heat pump hot water system
Double glazed aluminium windows
R2.5 wall insulation and R3.0 ceiling insulation
Low-flow tapware, sealed LED lighting and a laundry connected to mains and tank water

Why Quorrobolong Is Ideal for a Granny Flat
Set among the rolling hills of the Hunter Valley, Quorrobolong offers large rural lots with ample space for dual occupancy. The area falls within the Cessnock LGA, where zoning and lot sizes can often support secondary dwellings larger than 60m²—provided you go through the DA process.
It’s a great option for families who want to live together while maintaining independence, or who want to prepare for future flexibility.
Cessnock is a large town in the Lower Hunter Region, NSW. It is located 2 hours from Sydney, 45 minutes from Newcastle and just 15 minutes from wine country. This makes it an ideal position for the addition of a granny flat for either an investment opportunity or just creating more room for family members seeking the country lifestyle without being too far from the city.
A Great Outcome for Multi-Generational Living
This project allowed Sally and Ben to bring their family together under one roofline—without sacrificing privacy, space or comfort. From planning and council approvals to construction and handover, the Acrow team ensured everything ran smoothly, even with the additional complexities of flood and bushfire requirements.

Built in 2025 for Jess, this two-bedroom granny flat showcases how a standard design can be personalised to feel like a true home. Based on The Dock Plus layout and approved via CDC, this project in NSW proves that practicality and personality can go hand-in-hand.
The Design: The Dock Plus (Modified)
The Dock Plus offers a generous open-plan living, kitchen and dining layout—ideal for daily life or welcoming guests. Jess opted for a modified version of the design, incorporating:
Two bedrooms with built-in wardrobes
A shared bathroom with a separate laundry
An island bench in the kitchen for extra prep space and casual meals
A 3.5kW air conditioner for year-round comfort
Jess also upgraded the kitchen with black cabinetry handles and added a dishwasher, reflecting her focus on both form and function.
Steel Frame Construction and BAL 12.5 Adaptations
Built on bearers and joists with a steel frame and truss system, this home also met BAL 12.5 bushfire requirements—featuring aluminium flyscreens, eave vents, and a hardwood merbau porch and stairs. These additions not only offer peace of mind but contribute to a durable, long-lasting build.
Colour Choices That Make It Her Own Home
Unlike many secondary dwellings that lean toward neutral palettes, Jess brought vibrant character to her granny flat with:
Four different interior wall colours
Customised front door with Dulux “Golden Koi” at the entrance —a bold, warm shade that immediately sets her home apart
A unique blend of warmth, fun, and individuality that’s rarely seen in secondary dwellings
This personalised palette shows how small design decisions can make a big visual impact, adding charm and ownership to every room.
Ellalong Granny Flat Gallery
Granny Flat Delivered On Time with High Praise
The build commenced in mid-November 2024 and reached Practical Completion by early March 2025. Despite the Christmas break and minor delays, the project remained within the 12-week construction window. The final result not only met but exceeded Jess’s expectations.
Here’s what she had to say in her 5-star Google review:
*“We recently had our forever home built by Acrow Granny Flats, and we couldn’t be happier with the entire experience. From the very beginning, everything was well organised and ran smoothly. The process was quick, professional, and completely stress-free.
Crystal in the office was always prompt, friendly and helpful, Duke the sales manager guided us through the early stages with clarity and honest up front pricing and Dario our project manager made sure everything went to plan and was built to a high standard.
The quality of the build exceeded our expectations, and the whole team was a pleasure to deal with. If you’re thinking about building a granny flat, we highly recommend Acrow—professional, efficient, and genuinely great to work with.”*
Why Ellalong is Ideal for a Granny Flat
Ellalong is an ideal location for a granny flat thanks to its generous block sizes, peaceful rural atmosphere, and proximity to Cessnock and the Hunter Valley. The area attracts families, retirees, and renters looking for a quieter lifestyle with town conveniences nearby.

Whether you’re building for family, future flexibility, or additional rental income, Ellalong offers the space and setting to make a granny flat a smart investment.

Acrow Granny Flats recently achieved a record milestone by completing this gorgeous granny flat in Aberdare, Cessnock for our client, Anne. in just 8.5 weeks. Designed as a personal sanctuary on her daughter’s property, this build showcases the efficiency and quality that Acrow is known for.
Anne selected the Petit Plus design, a spacious one-bedroom granny flat layout perfect for comfortable living. With minimal alterations to the standard plan, she opted for timber-look overhead cabinetry inspired by our Cessnock display, an upgraded toilet, and panel glide blinds for the sliding door. One standout feature of the granny flat is the raked ceiling in the living, dining, and kitchen areas, creating an inviting and airy atmosphere.
The project was managed by our experienced team, with Mick as the Sales Manager and Dario as the Project Manager. The seamless construction process included weekly updates that kept Anne informed at every stage, ensuring her confidence and satisfaction throughout the build.
Anne’s experience with Acrow Granny Flats was nothing short of exceptional. She shared her thoughts in a glowing 5-star Google review:
“After analysing other companies against Acrow, it was easy to decide on Acrow with all the inclusions they offered on my 1-bedroom Petit Plus. The whole process was very smooth and managed well. Weekly communication throughout the process was effective, and it was good to know what was happening each week. I would recommend Acrow Granny Flats.”
Anne’s experience with Acrow Granny Flats goes beyond just building a structure; it’s about creating a space where she can thrive and enjoy her independence.
