How small can a house be for a building permit?

The Building Regulations used to prescribe how big your house had to be, now it’s very much about minimum function. In a previous postwe saw how its consumer law through building contracts that now defines and manages people’s requirements for specific projects, like size!

In the Uniform Building Regulations in Victoria through the 50’s and 60’s there must have been a perception that a house had to be a certain size to meet the basic functional requirements for cooking and washing (both yourself and your clothes).

Nowadays from a minimum legislative perspective the relevant objective in the Building Act is “to protect the safety and health of people who use those buildings and to enhance the amenity of buildings.” Building Surveyors are directed to Building CommissionPractice Note 2006-24 when they evaluate an application for an Occupancy Permit. As you can see size does not matter!

The project “Living in Small Spaces” at Kent Griswold’s blog “Tiny House Blog” shows what can be achieved with small spaces. In our modern age of scarce resources the average “project” home in Australia just seems to get bigger, although the land is often smaller. So here is the challenge “Living in Small Spaces”. Here’s a video from the Tiny House Blog on the tiny houses by Jay Schafer from Tumbleweed Tiny Houses:

Will your next building permit application be a you tube video on a flash drive?

Is this the future of building permit applications? Could a digital presentation of your building permit application be a “legal” document? We have 3d models using 3D drawing software? We can stamp pdf’s with an image of a stamp.

Is the legislation ready? Is it admissible as evidence? This ultimately would seem to be the key. In Victoria it’s the Evidence Act 1958 which is crucial. There is a whole section on business documents, with all sorts of exceptions and variations etc. It also says unless otherwise specified in an Act e.g. The Building Act 1993.

Regulation 302 of the Building Regulations 2006 mentions nothing about electronic documents. It just refers to documents. Section 32 of the Act says that a Council must keep all documents submitted in a “prescribed manner”. Regulation 321 is the key – it refers to records being kept for 10 years in their “original form”. So, if you submitted a permit application to BDC in digital form that would be the original form. OK, so far so good!

According to Johnathan Clough from the Monash University Law School in a presentation to the Public Records Office on the issue of “The Admissibility of Digital Evidence” section 3 of the Victorian Evidence Act 1958 says:

‘any disc tape sound track or other device in which sounds or other data (not being visual images) are embodied so as to be capable (with or without the aid of some other equipment) of being reproduced therefrom.’

How many levels above ground can an external fire hydrant serve with a building permit?

We all have rules of thumb we follow. Whether it’s an urban myth that works or the advice of someone we trust. Whether it’s an unusual project or we are just having an off day – sometimes we question these rules of thumb. Joe Zita, an associate of ours at Approval Systems mentioned to Building Design Compliance this  issue. Joe was on the money from the outset, but it took a couple of run throughs of the standard before we were convinced.

The “urban myth” that you can only provide external hydrant coverage to one level above the access level (typically the ground level) comes from this diagram above (Fig 3.2.2.2) from AS2419.1-2005. The note to the diagram only serves to  reinforce the “urban myth”. It says “Due to difficulties associated with fighting building fires, internal fire hydrants are required in fire-isolated stairs for levels more than one floor below ground and one or more levels above ground.”

Our understanding of the notes to these diagrams is that they provide guidance and are informative only. The must is in the text which says: (more…)
