Converting non-habitable building into habitable area (Class 10 to 1)

A building application to Council for a building permit is required for converting a Class 10 to a Class 1 (example: shed to dwelling) under the Building Act 1975 . 

To change the class of a building from a Class 10 building to enable it to be used for habitable purposes as a Class 1 building. A Class 10 building is generally not designed to comply with the structural performance criteria for a Class 1 type building (dwelling) as required under current building regulations. To ensure compliance with these regulations an application for building works is required.

Siting Requirements

The Queensland Development Code regulates siting requirements for single detached dwellings and Class 10 type structures.

Siting requirements under the Planning Scheme

A Planning Scheme may have ‘alternative provisions’ which provide boundary setbacks that conflict with the Queensland Development Code. Where such provisions exist, then those provisions override the Queensland Development Code. Check the Rockhampton Region Planning Scheme for any alternative provisions relating to boundary setbacks.

Wind Category Rating

The building work is required to be designed to comply with the wind rating of the property on which the development is to occur (either Non-Cyclonic or Cyclonic). The building plans/documents must confirm the design standard. To confirm the wind rating of your property contact either your nominated RPEQ Engineer, Building Designer or the authority nominated to assess the application

Documentation required to lodge a building application for this work:

General

  • Building Form - 1 Application details
  • Building Form - 2 Building work requiring assessment against the Building Act 1975 
  • QBCC if a register builder is engaged to do the work and the work is valued over $3,300
  • Owner Builder receipt if the owner builder is to do the work and the work is valued over $11,100
  • PLSL receipt details if work value >$80,800
  • Fees as per the current Fees Schedule.

Site Plan (min scale 1:100 – 3 sets)

  • Full outline of property and dimensions
  • Location of ALL existing buildings and clearly identify the building structure North point
  • Road frontages to be identified
  • Easements/covenant areas on the site
  • Distance of all buildings from the boundaries
  • Location of sewer / method of roof stormwater discharge on the site
  • Details of any site works that must be carried out as part of or for the development
  • Contours of the site after cut/fill
  • Location of rainwater tank (if installing).

Floor Plans (min scale 1:100 – 3 sets)

  • Floor plan – full dimensions
  • Elevation and section plans – full dimensions
  • Design details (either engineer specifications and/or bracing, timber schedule, tiedown details). Design is to also take into consideration the soil classification of the site where no soil investigation has previously been conducted. Council will accept a visual assessment from a suitably qualified Engineer (registered within the State of Queensland), however, where additional building work is greater than 50% of the existing floor area then a soil test investigation report is required.
  • Building floor level above adjacent finished ground level & site drainage system
  • Identify the use of the rooms
  • Smoke detector location/s
  • Method of termite treatment to be used
  • Wind category design details/certification
  • Energy efficiency design calculations
  • Window / door sizes.

Other Documentation

  • Engineer drawings/ specifications/ design certification (must use IPA Form 15)
  • Soil Classification.
