General contractors ensure the safe final assembly of a prefab tiny house. The following are some of the standards adopted by builders in prefab housing. The Housing and Urban Development and International Residential Code are the regulatory bodies.
Conventional Building Codes
The HUD had once mandated the standards for small prefab homes. They include:
- Limitations on Square Feet
- Standards on Room Size
- Ceiling Heights and Sanitary Standards
- Electricals and HVAC System Standards
The minimum square feet allocation for the prefab tiny house is 400sq ft and the maximum is 1000 sq ft.
Zonal Regulations and Square Feet
Zoning regulations define the type of prefab tiny house as per the locality. Not all prefabs could be mounted on a property much the same way in two different communities.
Zoning As Per the Floor Levels
Homebuilders understand that user specific prefab homes could be assembled easily from the modules. The IRC rules, for instance, define boundaries as per the floors involved in the final assembly kit. A single room prefab tiny house was 120 square feet once, which has become void following a new regulation in 2014.
The New Designer Series Home
The property in which modules are to be assembled should be the same during construction stage, as it is in the beginning. Last minute changes are difficult to implement in small prefab homes that have some amount of customization. Contractors dealing with the designer series homes manufacture the modules to fit properly to the plot. As long as they don’t deter from the standards, they will get permits quite easily.
Licensing of Prefab Homes
The thing that differentiates a prefab tiny house from an RV is the type of construction. Prefabs are permanent fixes whereas an RV is a manufactured home on wheels. To get licensed, builders should provide the details on the type of construction and the quality of materials used to the various governing bodies.
These days even indigenous contractors are licensed to assemble prefab tiny homes. What gives reputation to the small prefab homes is the word of mouth of the public. Builders and contractors team up in many cases, making it possible for the homeowner to sit back and relax while the home is manufactured in the factory.
