Do I require a building permit for these portable houses?
No. Because they are mobilised on triple axles and six wheels, with an ability to tow them, they are classified in law as caravans. As long as you can move them at reasonably short notice, with quick dis-connection, the test is satisfied.
Do I need permission from Council to site these portable houses?
Most Council’s do not require this, but it sometimes pays to check the local Council bylaws as it relates to “caravans”. Because these buildings are attractive, there should not be any issues.
Do I need permission to connect to Council water, sewerage and storm-water?
If required, you might obtain a plumbing consent from Council, or connect to your own services.
Can I go off-grid with these houses?
Very easily. These tiny homes can be powered with a combination of gas & solar power. A 1000 litre tank for septic at little cost. Roof water, a holding tank and an in-line water pump.
