Do I need both a planning permit and a building permit for my residential project?
Whether you need a planning permit, a building permit, or both depends on the nature and location of your proposed works. A planning permit, issued by the local council, determines whether the development is appropriate for the site by considering matters such as zoning, overlays, neighbourhood character and land use. A building permit, issued by a registered building surveyor, confirms that the proposed construction complies with the Building Act 1993 (Vic), Building Regulations 2018 (Vic) and the National Construction Code (NCC) 2025.
If a planning permit is required, it must be obtained before a building permit can be issued. Our team works closely with homeowners, designers and planning consultants to ensure planning requirements are addressed early, helping to minimise design changes, avoid unnecessary delays and streamline the building approval process.
Who can issue a building permit and how do I appoint a building surveyor?
Building permits in Victoria are issued by either a private registered building surveyor or a municipal building surveyor (council). You must appoint a registered building surveyor to assess and issue the building permit. Always verify the practitioner’s registration via the Building & Plumbing Commission’s practitioner directory before engagement, and appoint them early so they can assess your documentation and clarify what mandatory inspections may be required.

What mandatory inspections will my project require?
Mandatory inspections are staged to verify compliance at key construction points and will be listed on the building permit. The mandatory inspection stages required in Victoria are (residential and commercial) foundations, footings, frame and final inspections. For Class 2–9 commercial projects, Essential Safety Maintenance (ESM)schedules and services often require independent verification during construction and at completion. Our inspection team manages and records all prescribed inspections, liaises with builders to schedule timely site checks and ensures ESM documentation is prepared and retained, thereby reducing the risk of incomplete records or delays to practical completion. A Certificate of Final Inspection or an Occupancy Permit are subsequently issued after a compliant final inspection has been undertaken for a project.
What are the most common reasons residential building permits are delayed, and how can delays be prevented?
Residential building permit applications are often delayed because of incomplete documentation, inconsistencies between plans and supporting reports, unresolved planning permit conditions, or insufficient information to demonstrate compliance with the Building Regulations 2018 (Vic) and National Construction Code (NCC) 2025.
Many of these issues can be avoided through careful preparation before the application is lodged. Engaging a registered building surveyor early, ensuring plans and specifications are complete, and coordinating with designers, engineers and other consultants helps reduce requests for additional information during the assessment process. Our team undertakes detailed pre-lodgement reviews, identifies potential compliance issues before submission and manages communication with councils and referral authorities to help achieve timely permit approvals.
What exactly are Class 1 and Class 10 building classifications?
A Class 1 building classification applies to dwellings, including detached houses, townhouses, terrace houses, and small secondary dwellings, as well as associated decks and verandahs. A Class 10 building classification applies to non‑habitable structures such as sheds, carports, private garages, fences, masts, antennas, retaining walls, swimming pools, and private bushfire shelters. The National Construction Code (NCC) 2025 determines the applicable technical and regulatory requirements. When you appoint our building surveyor practice, our registered surveyors confirm the correct classification at the outset, ensure documentation and inspection pathways align with the applicable code.
How can early engagement with a building surveyor help my Class 1 or 10 project?
Engaging our advisory team at the design stage helps identify siting, compliance and documentation issues early, reduces the risk of permit delays, minimises redesign costs and clarifies which inspections and reports will be required once construction commences. Early advice is particularly valuable where siting, bushfire attack level (BAL) ratings, or multiple approvals may apply.
How do siting rules affect building Class 1 and Class 10 approvals?
The siting provisions in Part 5 of the Building Regulations 2018 (Vic) control setbacks, overshadowing and related matters; they generally apply where a planning permit is not required and may apply even when a planning permit is issued for the project. Our building compliance specialists review siting against the Building Regulations 2018 (Vic) at project commencement, advise on compliant layouts or the need for Report and Consent, and document the chosen approach on plans. By addressing siting design matters early we prevent permit hold‑ups, protecting the project schedule and budget.
What happens if my plans don’t meet a siting or other regulation requirement?
If a proposal varies from the Building Regulations 2018 (Vic), a Report and Consent or other statutory application to the local council may be required. Our residential building compliance specialists prepare the requirement checklist and can assist you in compiling the necessary documentation to lodge with council.
How can I determine if my residential project requires an Occupancy Permit or a Certificate of Final Inspection?
The type of completion certificate required for your project will be determined as part of the building permit process. New homes always require an Occupancy Permit before the building can be lawfully occupied, whereas alterations or extensions generally require a Certificate of Final Inspection.
These documents confirm that all mandatory inspections have been completed and that the approved building work satisfies the relevant legislative and safety requirements. Our building surveyors review your permit conditions, coordinate outstanding inspections where required and ensure the necessary documentation is in place so your project can be finalised efficiently and in compliance with Victorian building legislation.
If I’m an owner‑builder, are there extra requirements for building Class 1 or 10 work?
Owner‑builders must satisfy statutory owner‑builder consent requirements and provide the documentation specified in the Building Regulations 2018 (Vic); some owner‑builder work is subject to additional limits. Our building surveyor practice advises on the precise owner‑builder evidence and documentation required for permit lodgement and ensures the submission meets statutory expectations to avoid delays or refusals due to incomplete paperwork.
What if my proposed structure is exempt from a building permit – how do I confirm that?
Some small Class 10 works are exempt from a building permit, but whether an exemption applies depends on a range of factors, including size, height, location relative to boundaries, and local planning overlays, which can lead to misinterpretation. Our permit coordination team reviews your plans and site context and confirms whether the work is exempt or whether a building permit and inspections are required, removing uncertainty and preventing costly mistakes from assuming exemption incorrectly.
How close can I build a wall or shed to my side or rear boundary?
Setbacks for side and rear walls are governed by Part 5 of the Building Regulations 2018 (Vic) and depend on a variety of design parameters. Our technical team assess your proposed plans and calculate the exact setbacks applicable for your site.
How close can I build a deck to the boundary?
Building a deck to the boundary requires compliance with the fire separation requirements of the National Construction Code (NCC) 2025 and applicable siting requirements. Our technical team assesses the deck design against all construction requirements and siting rules, ensuring your home is safe and compliant for long-term use.
Can I build a garage or carport on the boundary?
Garages and carports can be built on boundary and are required to comply with the National Construction Code (NCC) 2025 and Building Regulations 2018 (Vic) (for example, Regulation 80: provisions for walls on boundaries). Our technical team checks the design against the relevant regulations, advises whether a boundary wall is acceptable and directs you in lodging any required report and consent documentation.
What are the rules for front fence heights and corner lots?
Front fence heights are regulated under the Building Regulations 2018 (Vic) (Regulation 89 and related clauses) and may also be affected by local planning controls. On corner lots, visibility splays and intersection sightlines are critical – fences within specified distances of the street alignment must meet maximum heights to maintain intersection sightlines.
How do bushfire attack level (BAL) requirements affect Class 1 & 10 structures?
Bushfire attack level (BAL) ratings apply where your property is in a bushfire‑prone area and can affect construction standards for both Class 1 dwellings and associated Class 10 structures. A BAL assessment may change required materials, clearances and construction details. Our residential building compliance specialists check whether your site is in a designated bushfire area, advise on required BAL documentation and coordinate compliance measures with your designer so the permit application and construction meet the necessary bushfire standards.
Do I require a building permit for my commercial project?
Under Victorian legislation, commercial building work requires a building permit before any construction commences. A building permit confirms the proposed work complies with the Building Act 1993 (Vic), the Building Regulations 2018 (Vic) and the National Construction Code (NCC) 2025. Some very minor works may be exempt, but exemptions are specific and site‑dependent. Our registered buiding surveyors review the scope of works and site context to determine whether a permit is required, and where exemptions are borderline we provide a definitive assessment. Engaging our permit coordination team early prevents unlawful commencement, reduces the risk of enforcement action and ensures the project proceeds on a compliant, auditable basis.
What is the difference between a planning permit and a building permit?
A town planning permit, issued by the local council, regulates land use, siting, heritage, external appearance and broader development outcomes. A building permit, issued by a registered building surveyor, certifies that the building design and construction meet building regulations and technical standards. Where a town planning permit is required, it must be obtained prior to lodging a building permit application.
Who can issue a building permit and how do I appoint a building surveyor?
Building permits in Victoria are issued by either a private registered building surveyor or a municipal building surveyor (council). You must appoint a registered building surveyor to assess and issue the building permit. Always verify the practitioner’s registration via the Building & Plumbing Commission’s practitioner directory before engagement, and appoint them early so they can assess your documentation and clarify what mandatory inspections may be required. Victorian Building Authority building surveyor practitioner directory.
What mandatory inspections will my commercial construction project require?
Mandatory inspections are staged to verify compliance at key construction points and will be listed on the building permit. The mandatory inspection stages for commercial projects include foundations, footings, frame, fire safety systems, Essential Safety Measures (ESM) checks and final completion. For Class 2–10 projects, ESM and services often require independent verification during construction and at completion. Our inspection team manages and records all prescribed inspections, liaises with builders to schedule timely site checks and ensures ESM documentation is prepared and retained, thereby reducing the risk of incomplete records or delays to practical completion. A Certificate of Final Inspection or an Occupancy Permit are subsequently issued after a compliant final inspection has been undertaken for a project.
When do I need an Occupancy Permit or a Certificate of Final Inspection?
The building permit will specify whether an Occupancy Permit or a Certificate of Final Inspection is required on completion. An Occupancy Permit is typically required for new buildings or where a change of use affects safety or amenity; a Certificate of Final Inspection may apply to all other construction work (additions/alterations, fences, carports etc.). These instruments confirm that mandatory inspections are complete and that the building is suitable for use. Our compliance specialists review the building permit conditions, coordinate any remaining inspections and compile the evidence required for the relevant certificate, enabling lawful occupation and reducing exposure to post‑completion compliance issues.
What are Essential Safety Measures and how do they affect my project?
Essential Safety Measures (ESM) include fire detection and suppression, exit lighting, emergency signage, hydrants and other life‑safety systems. ESM must be documented in the permit, installed to National Construction Code (NCC) 2025 standards, and maintained after handover. We provide Essential Safety Measures (ESM) audits, maintenance schedules and statutory certification to ensure ongoing compliance.
Do commercial buildings in Victoria need to be accessible for people with disability, and will I need a building permit to carry out accessibility upgrades to my commercial premises?
Accessibility requirements in Victoria are governed by the National Construction Code (NCC) 2025, relevant Australian Standards (including AS 1428), and the Disability (Access to Premises – Buildings) Standards 2010. These frameworks work together to set the minimum requirements for equitable access to and within buildings, and apply to new buildings, as well as alterations or additions to existing buildings, and buildings undergoing a change of use.
If you are upgrading your commercial premises – such as installing ramps, accessible toilets, lifts, or modifying entrances – these works will often require a building permit.
In some circumstances, even partial upgrades may trigger a requirement to improve overall accessibility to ensure the building complies with current standards.
As registered building surveyors, Hornsby Building Surveyors can assess your proposed works, determine whether a building permit is required, and advise on your obligations under the National Construction Code (NCC) 2025, the Premises Standards (Disability (Access to Premises — Buildings) Standards 2010), and Victorian building legislation (Building Act 1993 (Vic); Building Regulations 2018 (Vic)). Seeking advice early can help ensure compliance and avoid delays or costly redesign.
What commonly causes commercial permit approval delays and how can I avoid them?
Common causes of delay in approving commercial building permits include incomplete or inconsistent documentation, unresolved planning conditions, unclear fire safety or accessibility solutions, and late submission of Essential Safety Measures (ESM) details. To avoid delays, appoint a building surveyor early, prepare complete drawings and specialist reports, and coordinate planning, fire engineering and services consultants prior to lodgement.
What role do you provide as building surveyors and consultants for commercial Class 2–10 projects?
