Cafés and Restaurants
Guidance on information required for Café/Restaurant fitout
This guidance document has been prepared to assist applicants and their agents in the use of the relevant sections of the Building Act 2004 (the Act) and NZ Building Code.
If this is a first time fit out of a new building, all work must fully comply.
If this is for the fit out of an existing building, Section 115 (Change of use) is applicable.
If this is for an existing café/restaurant, please refer to sections 112 and 118 of the Act for direction on what is required.
For existing buildings, the consents that are processed with fewer requests for further information (RFIs) are the ones supported by a good quality “As Near As Reasonably Practicable” (ANARP) report. This report should cover all code clauses and the following specific points:
- Current situation - (what is the existing lawfully established use?)
- What does 100 percent compliance look like for the proposed work?
- An upgrade action plan should be provided to determine what is reasonable to upgrade as required by Sections 112 or 115 of the Act.
- The action plan should provide reasoning for not fully upgrading to current standards. Evidence would need to be supplied to support the decision not to fully upgrade or why no changes to the existing have been made.
Note: Before a building consent can be granted, sections 112 and 115 of the Act requires the building consent authority to be satisfied that the existing building, or part of a building, complies with requirements for a
- means of escape from fire to a safe place and
- access and facilities for people with disabilities to what is reasonably practicable.
This means for an existing building; Council will decide what is reasonably practicable re compliance as it is not a new building. The intention of sections 112 and 115 is to ensure that buildings are upgraded to enable them to be safer or more useable to occupants.
Simple low-cost upgrades such as door handles, taps, signage, handrails, and the like are likely to be required as a minimum.
For new buildings, an accessibility report is to be provided with the consent application to demonstrate compliance with New Zealand Building Code requirements as applicable.
Providing a floor plan on its own without an accessibility report is likely to cause delays in the consenting process.
The accessibility report should begin from the start of the journey into the building (such as the accessible car park) if a carpark is required, then on to the main entrance of the building and throughout showing the full extent of accessible routes.
The designer should consider door thresholds, widths, handles and hardware (taps, switches) plus electrical light fitting heights etc. throughout the building along the accessible route.
For example, the designer should imagine themselves to be in a wheelchair when writing the report and consider where do I park, how do I get to and enter the building, where is the counter and toilet facilities etc.
The application must demonstrate correct number of toilet facilities under G1 and required accessible and plus hand-washing facilities. If a new accessible toilet facility is to be provided in an existing building, access to the new toilet must be considered. It is critical to ensure that access is compliant from the entrance of the building to all facilities within.
The designer could also imagine themselves escaping from a fire to the “safe place”. Any obstacles that are not permitted in a safe path (gas bottles, electrical boards, and the like) would need to be considered. Consider also any non-compliant door hardware to final exits, internal and external changes of level, gates, and enclosed courtyards surrounded by 2 m high concrete block walls.
G5: Interior Environment
Performance Clause G5.3.4 requires that where reception counters are provided in commercial buildings for public use, then at least one counter will be accessible. Consent documentation information should be provided identifying how compliance will be achieved.
Accessible counter NZBC G5/AS1 refers to NZS 4121.2001 and NZBC F8/AS1 for signage.
Note: if there is no requirement to fill out a form or sign a document then a max 900 mm high counter could be acceptable as this will ensure it is accessible to everyone and means the users on both sides can carry out normal activities and processes related to the counter. This needs to be clearly documented on the building consent plans and accessibility report
It is not generally acceptable to have a high counter as it is important to see and be seen, make eye contact and be in hearing range without being obstructed by the counter. Be aware of the space needed for the accessible toilets - the dimensions must be taken from the inside of the lined walls. If taken from the framing the rooms may be non-compliant, remember the code and acceptable solutions show only minimums of what is required.
A fire report to C1-6 as applicable needs to be provided with all applications to demonstrate means of escape from fire and protection of other property where applicable.
A fire report is required to recommend alarm systems, occupancy numbers, fire rating required, emergency lighting recommendation etc. This can also help with the deign process for what is required for other code clauses such as G1 for toilet facilities required with the occupancy number etc.
A fire report may not be required for some very minor works. In these cases, a written statement from a suitably qualified person should be provided to clearly explain why the C1-6 clauses do not apply to this application.
Grease trap type and size should be assessed by Council’s trade waste team prior to consent application as a Trade Waste Consent and site inspection maybe required. External in-ground conventional passive grease traps are preferred by council infrastructure, see G13/AS2 section 3.4. These should provide enough capacity to function efficiently between cleaning and maintenance intervals. The minimum size of a passive in-ground grease trap is 500 litres or 500 litre equivalent alternate solution. Alternate solutions will only be accepted with supporting documentation with consent application.
Please email TradeWaste@westernbay.govt.nz for more information.
Alternate Solution G14/VM1 section 1.2
If you are unable to install a conventional in-ground exterior grease trap as per the “Acceptable solutions of G13” and propose an alternative solution such as an under-bench grease trap system, you will be required to identify the following on your Building Consent application and supply supporting documentation:
- G13/AS2 section 3.4.7 Other types of grease trap such as those that separate, or digest grease must be reviewed for approval by the network utility operator as required by G14/VM1 1.2.1.
- The reasons why you cannot use a conventional in-ground grease trap for the trade waste team to review, including drainage/building plans and photos.
- Sizes/capacities of sanitary fixtures and appliances discharging into grease trap.
- Sizing of the under-bench grease trap system should only be done with prior approval with Council’s trade waste team and each one will be judged on a case-by-case basis. If it was approved in one situation does not guarantee it will be suitable in another.
- Size and type of grease trap, inclusion of tamper proof sink screens or solids capture devices and a testing port on unit.
- Calculations that support the size of the grease trap as per G13/AS2 Section 3.4
- Manufacturers details and specification of the Grease trap.
- An operation and maintenance schedule for the under-bench grease trap system.
- The maximum seating capacity of restaurant (fire report.)
- A service and maintenance agreement, proposed maintenance frequencies, including service provider.
- Provide sufficient access to the unit for cleaning and maintenance.
- Proposed location of the grease trap detailed on plans.
If you have any further queries, please email TradeWaste@westernbay.govt.nz

Note: fire report requirements may include a fire suppression system as part of the rangehood and supporting information on this will be required.
See Performance Clause G4.3.3, Performance Clause G4.3.5 for code requirements.
Please provide a set of complying maintenance, inspection, and reporting procedures for the mechanical ventilation systems in the building, this required as part of the building consent documentation.
G8: Artificial light requirements:
Please provide information to demonstrate that spaces within the building have enough artificial lighting (min. 20 lux at floor level). When activated in the absence of sufficient natural light, the artificial light should enable safe movement.
The lighting design will also need to cover (F6 Visibility in escape routes) emergency lighting if required (including external changes of level) along the escape route to the safe place if they have not been considered by the fire designer.
Please also include information on the types of lights used and design standard for the compliance schedule.
NZBC G9 Electricity - Performance Clause G3.3.3 requires an adequate energy supply is provided for cooking and refrigeration appliances.
An electrical plan should cover this along with the height levels for accessible power and light switches.
Performance Clause G9.3.1 details performance criteria to be meet
G10: Piped Services Gas supply
Please supply details on
- Cooking hobs etc where gas is the power source
- Gas hot water systems etc
- Any system that uses gas as the power supply
NZBC G10 Piped Services - Performance Clause G10.3.5 requires that enclosed spaces will be constructed to avoid the likelihood of accumulating vented or leaking gas.

Note: If you have any questions contact your local IQP and they will help you with what’s required as they will be certifying this as part of the compliance schedule.
G13: Sewer pipes/drains, new or existing drains
Items you will need to consider for code performance requirements for the design path selected either G13/AS1 or AS/NZS3500.
Note: If you need to cut the floor slab to install new sewer pipes, you will need to detail the means of reinstating the floor slab. You may need to engage an engineer for this to ensure the structural integrity of the floor slab has not been compromised.
If the fitout contains some Structural engineering design, please ensure all structural engineering design sketches are replicated in the design drawing detail sheets that are
1. in CAD
2. to min standard of AS/NZS1100
3. to scale and referenced back to larger scale plans.
Hand sketches pasted onto drawings will not be accepted.
If the tenancy fitout is to have a suspended ceiling, the design will need to include the seismic fixings with supporting calculations and details and manufacturers system information if using a proprietary suspended ceiling system.
F2: Hazardous building Material
Glazing to the front of the tenancy must also be considered for your fit out or new build.
In some cases, the tenancy front is fully glazed, and you will need to consider the requirements for manifestation to glazing to comply with F2.3.2.
NZS4223.3:2016 details requirements for manifestation to glazing.
Any new installation or alteration to a specified system requires confirmation of the performance standard the system is designed to, and the inspection, maintenance and reporting procedure. This may be by way of a cited standard, acceptable solution section or specific design.
Any change to the performance standard during construction process will require a consent amendment, so this needs to be correct. These performance standards and IMR procedures need to be consistent across all the documentation. Any discrepancy across documentation will result in a request for further information being issued.
Manifestation – Marking of glazing to make it visible.
Specified System - Buildings that contain certain safety and essential systems, known as specified systems, need a compliance schedule.
IQP – Independent Qualified Persons.
IMR – Inspection Maintenance Record.
BWoF – Building Warrant of Fitness.
