The siting requirements of a single dwelling and the associated outbuildings, on a site with an area exceeding 500 m2, can be found in Division 2 of Part 4 of the Building Regulations 2006, however allotments in the City of Bayside are in a zone of the planning scheme that are specified in Schedule 5 of the Building Regulations in respect of regulations 409, 411, 414 and 424 which vary the siting requirement of these regulations.
This means that frontage setbacks, site coverage, side & rear setbacks, and front fence heights differ from the regulations specified in Part 4. These variations can be accessed in our information sheet titled - The C2 Amendment – Additional Siting Requirements
The following is an information sheet on the siting requirements for single domestic dwellings in the City of Bayside which incorporate the additional siting requirements referred to in Schedule 5 of the Building Regulations:

Walls on Boundaries (regulation 415)
Walls of a building and carports can be constructed to the side or rear boundary of an allotment, (unless prohibited by regulation 417), provided
- The maximum length of wall/s and carport/s on or within 200mm a shared allotment boundary, with an adjoining property, must not exceed 10m plus 25% of the remaining length of the shared boundary. (Note: If a proposed wall abuts an existing neighbouring wall on the boundary, then it can be constructed to the same length of the wall it abuts.)
- The maximum average height of a wall or carport on or within 200mm to a side or rear boundary must not exceed 3.2m and a maximum height of 3.6m. (Note: If a proposed wall abuts an existing neighbouring wall on the boundary, then it can be constructed to the same height of the wall it abuts.)

Please note that the setback requirements of regulation 417 are often less than the setback requirements of regulation 414, in which case regulation 414 takes precedent.
Overshadowing of Neighbours Recreational Private Open Space (regulation 418)
After a building is constructed, a minimum of 75% or 40m2,with a minimum dimension of 3.0m (whichever is the lesser), of an adjoining neighbours “recreational private open space” must receive a minimum of 5 hours of sunlight between the hours of 9am and 3pm on the 22 September.
If the adjoining allotment does not already receive the above amount of sunlight on the 22 September, then the constructions on the adjoining allotments cannot further reduced sunlight to the neighbour’s secluded private open space.
Note: “recreational private open space” is any part of private open space which is primarily intended for outdoor recreational activity and is either at the side or rear of an existing dwelling, or in front of a dwelling if it is screened with a 1.5m high fences or walls (which are no more than 25% open) for at least 90 % of the perimeter of the private open space.
“Private open space” is an unroofed area of land or a deck, terrace, patio, balcony, pergola, verandah, gazebo and a swimming pool.
Overlooking (regulation 419)
A habitable room window, a landing with an area of more than 2m2, a balcony, terrace, deck or a patio (which is 800mm or more above natural ground level, measured at the boundary) must not provide a direct line of sight into a “secluded private open space” or a habitable room window of an existing dwelling on an adjoining within a 9.0m distance, measured at ground level, of the window, landing balcony, terrace etc.
Note: A direct line of sight is measured within a 45o angle from the plane of the window, landing, balcony etc from a height of 1.7m above the floor level of the room, landing, balcony, terrace, etc
A habitable room window complies if it;
- is offset a minimum of 1.5m from the edge of one window to the edge of the other window, or
- has a sill height of at least 1.7m above floor level, or
- has fixed obscured glazing in any part of the window less than 1.7m above floor level, or
- is obscured by a permanent fixed screen, which has more than 25% of its area open.
A landing. deck, balcony, etc complies if the direct line of sight is obscured by a permanent fixed screen which has no more than 25% of its area open.
If the floor level of a habitable room, or the level of a raised open space, is less than 800mm above natural ground level, measured at the boundary, and there is a 1.8m high visual barrier at the boundary, then the overlooking requirements of the above Regulation do not apply.
Note: “secluded private open space” means private open space which is primarily intended for outdoor recreational activities and which is screened for a least 90% of its perimeter by walls, fences, screen etc which are no more than 25% open and at a height of at least 1.5m.
Daylight to New habitable Room Windows (regulation 420)
A new habitable room window must face:
- an outdoor space on the allotment with an area of 3.0m2 and a minimum dimension of 1.0m, or
- a verandah on the allotment, if it is open on at least 1/3rd of its perimeter, or
- a carport on the allotment, if it is open on at least 1/3rd of its perimeter and has two (2) sides open.
Note: a side of a verandah or carport is considered open if it is not less than 500mm from another building or boundary).
Private Open Space (regulation 421)
A minimum 80m2 or 20% (whichever the lesser) of private open area must be provided on the allotment. Of this private open space, a minimum 25m2, with a minimum dimension of 3.0m, must be provided at the side or rear of the building, with convenient access from a habitable room (other than a bedroom).
Applications to vary the siting requirements can be made to Council. This is called a ‘Report and Consent’ and applications for these siting dispensations must include details that support the application, justification that the applications meet the Ministers Guidelines and comments from the nearby effected property owners.
Please refer to our information sheet on ‘report and consent’ (Siting Variations) Process regarding these applications.
For further information please contact Council’s Building Surveying Department on (03) 9599 4444.
Siting of Single Dwellings and Outbuildings
Part 4 of the Building Regulations regulate the siting of single dwelling and their associated outbuildings on allotments. Our information sheet on siting gives an abbreviated account of the provisions of Part 4 of the Building Regulation in the City of Bayside, incorporating the four (4) additional requirements that are included in Schedule 5 of the Building Regulations.
The regulations specify the minimum standards that apply to building heights, setbacks, site coverage, open space, maximum impermeable surfaces, daylight & solar access requirements, overlooking and overshadowing. The Schedule 5 additional requirements apply to front setbacks, side & rear setbacks, site coverage and front fence heights.
These schedule 5 requirements can be viewed on our information sheet titled ‘The C2 Amendment’ – Additional Siting Requirements
Dispensations (Siting variations) Applications
The Building Regulations allow for a ‘report & consent’ application to be made to Council seeking a variation to the siting requirements, where an applicant has difficulties in meeting the requirements.
This process is set out in Schedule 2 Parts (4), (4a) & (5), and Section 188A of the Building Act 1993 which refer to the relevant Minister’s Guidelines that need to be met before consent to vary the siting requirements can be given.
The application form (that sets our fees), an information sheet (that sets out what documents need to be submitted in respect of a ‘report & consent’ application) and the nearby affected neighbours comment form, can be accessed on the building forms page.
The Bayside Neighbourhood Character Review, that needs to be referred to in terms of neighbourhood character, is called up as part of the Ministers Guidelines and Bayside Neighbourhood Character precinct brochures
You will need to establish which neighbourhood character precinct a specific site is situated before accessing the appropriate precinct brochure. This can be done by contacting the Planning Department on (03) 9599 4444.
