NOAH Certified

  • NFPA 1192 - National Fire Protection Association

  • NFPA 70 (NEC) - National Electrical Code

  • IRC - (International residential code) With Appendix Q for tiny houses

  • ANSI 119.5 - American National Standards Institute

Inspections are performed at all critical stages of construction for compliance to The ANSI+ Standard. NOAH inspectors are Certified Professional Inspectors, utilizing InterNACHI CPI’s, Engineers, General Contractors, Plumbers, Electricians & Building Inspectors.

Inspections are performed by individuals, in-person or remotely, using an expert mobile application which can be hosted anywhere in the world. Recording of live stream video & audio allow the inspector to guide the builder through each inspection stage. Inspectors can also take snapshots/photos during video & make annotations to thoroughly document specific details.

NOAH maintains all inspection records for each NOAH Certified Structure using AES-256 encryption of data stored in world class secure facilities that meet PCI, HIPAA, Military and other regulatory requirements. Records are stored and retrievable by identifiers:

  • VIN - Vehicle Identification Number/or Other Identifier

  • NOAH Certification Seal Number

  • Builder Name

As stated above, each build gets inspected 5 separate times during the build.

Stage 1 Inspection - Trailer frame

  • VIN permanently attached

  • Dimension of frame and tongue metal

  • Cross-member spacing

  • Total trailer weight rating or axle weight rating

  • Number of axles, lug pattern, brakes, coupler size

  • Length and width of frame

House length & required trailer capacities:


18' » 7,000 - 9,000 lbs

24' » 9,000 - 12,000 lbs

32' » 12,000 - 16,000 lbs

If your trailer doesn't have a total weight rating tag on it or a weight rating tag on the axles, here's a guideline to assist you:

Typical Axle Diameters Based on Axle Capacity

3,500-lb axle: 2 3/8-inch diameter

6,000-lb - 7,200-lb axle: 3-inch diameter

8,000-lb axle: 3-1/2-inch diameter

9,000-lb axles: 4-inch diameter

10,000-lb or more axles: 5-inch diameter
