NOAH Certified Inc dba NOAH RDI.

NOAH is a national trade association for builders (manufacturers & do-it-yourselfers) producing Structures, suitable for permanent, full-time residential living or temporary habitation.

1. Vision, Mission & Goals

Vision: All inspected Structures built to The NOAH Standard.

Mission: Provide inspection & certification services for builders.

Goals: Promote & protect its members by:


  • Pursuing favorable business environments for NOAH members
  • Promoting the health and wellbeing of NOAH, the NOAH Standard & Members
  • Creating a safe & positive experience for consumers
  • Providing industry information & knowledge
  • Fostering continuous improvement of products or services


2. NOAH Builder Membership

NOAH Certification is a voluntary program for builders to demonstrate compliance with safety, construction & energy efficiency standards for consumer confidence in the product(s) they produce. The builder pledges to build to the Noah Standard. NOAH inspects the build at critical phases of construction to confirm compliance.  NOAH certifies the build, not the builder.  Builder membership is a requirement for access to the NOAH inspection & certification service.


3. The NOAH Standard

The NOAH Standard incorporates portions of nationally recognized standards for safety, energy efficiency & construction, from multiple industries & associations. Those industries include the Recreational Vehicle, Homebuilding, Transportation Industries & IRC including 2018 Tiny House Appendix Q.


  • 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


4. Inspection Services

Inspections are performed at all critical stages of construction for compliance to the NOAH 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

Standards Enforcement

If the build does not pass inspection at a stage, a re-inspection can be performed once, at no additional fee. After the second inspection, if the build does not pass, there will be a re-inspect fee, receivable before issuance of the NOAH Certification Seal. Builders failing or refusing compliance are subject to disciplinary action ranging from membership probation (resulting in more frequent inspections & re-inspection fees) to expulsion from NOAH membership.

Five Inspection Stages (Note: Skoolies/Vehicle Conversions/ RV Rehabs omit stage 1 & 2)


Stage 1 Inspection

Trailer frame

  • VIN label
  • 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:

Length                                                  Average finished weight

18'                                                          7,000 - 9,000 lbs

24'                                                          9,000 - 12,000 lbs

Preparing for Inspection

These instructions are available in your Member Portal along with links to inspection videos

Step 1: Please review all Steps 1-7, first.

We want to make the inspection process easy & efficient for you and our inspectors. Reviewing the information & completing each step prior to scheduling an inspection will ensure the best possible outcome.


Step 2: Download Inspection App

Please install the GoToAssist Seeit (Citrix) App onto your Smart Phone. The App is free & available in the Apple & Android App Stores

The GoToAssist Seeit App lets you share what you see through your Smart Phone’s camera with an inspector. You control the activation of your camera & microphone to allow access to our inspector. At the end of the session you & our inspector will disconnect the call to close the app.


Step 3 A & B: WIFI Signal & Preview Inspection Process

  1. Please verify that you have a strong Wifi signal with connection to the internet in the location of your Structure, where the inspection will take place. This is imperative for the best quality video & images.
  2. Inspection Process


Preview Inspection Process

Stage 1 Trailer: (May not apply to all Structures)

All inspections start with the VIN or identifier. The inspector will inspect the coupler and breakaway switch. He will look at the tire ratings, lug pattern, electric brakes and axle ratings. Have a measuring tape ready to measure the size of the trailer framing members, the length and width of the trailer bed and the measurements on the tongue. He will inspect the lighting and safety chains on the trailer also. NOTE: If your trailer has a metal pan and you will be covering the floor insulation with floor sheathing; please Schedule an Insulation Inspection prior to covering.


Stage 2 Framing: (May not apply to all Structures)

Inspector will be inspecting the framing, sheathing (with all straps and anchors), headers, rafters, rafter ties, loft framing, interior wall framing, studs, plates, SIPs panels and engineered metal framing. The minimum ceiling heights of kitchens and baths is 6’4”. He will also be looking at the nail pattern of the sheathing (roof and wall) and the rough opening for the primary and secondary means of egress. Inspectors will be checking the size of the structure to ensure all legal requirements are met. NOTE: Please have a ladder and tape measure ready for each inspection.


Stage 3 Rough Trades will include:

  1. Rough plumbing including… supply lines with pressure test of 80-100 lbs., drain lines and gas lines with pressure test of 10 lbs.
  2. Rough electrical…
  3. Rough Mechanical will include mainly Freon lines if a mini split is used
  4. House wrap including the ice and water taping around the windows
  5. Roof Underlayment

NOTE: Rough Trades (A. through E.) may be scheduled separately, as needed.

Stage 4 Insulation:

Minimum R value.  Inspector may look at weather-stripping on the doors and U value on widows.

NOTE: Builder should have the area between doors and windows and the framing either caulked or insulated.

Step 4: Schedule Inspection

Log into your NOAH Member Portal using the credentials provided to you at the time of registering your NOAH Membership.

Choose the Schedule Inspection button located at the top of the portal. You will be directed to choose the inspection Stage, and the day & time you would prefer for your inspection.


Stage 5 Final:

Inspector will be looking for (where needed): the smoke and CO detector, fire extinguisher within 2’ of the main entry door, stairs and rails if needed and ceiling heights.  Inspector will also be verifying  secondary means of egress is properly labeled (with the word “EXIT” in 1” high Red letters), and the minimum size for the secondary egress. Inspectors will be re-checking the size of the structure to ensure all legal requirements are met.  Builder shall have a polarity and GFIC tester during this inspection. Builder will perform the factory tests per NEC Article 551.60 and attests to passing said tests. Inspector may also require random testing of polarity and GFCI.

Please schedule your inspection with at least 24-hours’ notice, whenever possible. You will receive an email confirmation of your Inspection Request.

Step 5: Inspection Appointment

Within 15 minutes of your scheduled inspection you will receive a text containing a session link from your inspector.

When you receive your session link,  click on the link in the text to access the app: Your smart device may ask you if it's okay to go to this link. Please click OK.

Next, your smart device will ask which app to open with - choose GoToAssis Seeit. The app will open, the session number will appear & you will need to click JOIN SESSION.


Step 6: Turn on Microphone

Turning on the microphone will allow you & your inspector to speak to one another during the inspection. The inspector will see what you are seeing through the camera of your smart device.

It may take 5-10 seconds for the camera to focus, especially after moving quickly. Initially, hold the phone/camera facing an object, such as the VIN sticker on the tongue of the trailer. Stay still while listening to the instructions from the inspector. Then move slowly as you proceed and as directed by the inspector. A strong wifi signal is necessary to produce the best quality images & video.

The inspector may ask you to pause so they are able to capture a still image. Again you will see what they see. They may place an arrow or other remarks on the still image. After providing additional instruction they may continue with video...


Step 7: Session Completion

Your inspector will make notes about the inspection before disconnecting the session. Please do not disconnect until you are advised.

Before the completion of the call, you will be notified of passing the inspection so you may continue to the next phase of inspection. If there is a need for re-inspection you will be able to schedule in the member portal when you are ready.

Your inspection(s) will be saved as part of your member record with NOAH. They will be available to you in the future, by request at or 866-664-6624.


6. Builder Quality Assurance Program

The NOAH Standard incorporates minimum standards from NFPA, NEC, ANSI, DOT/NTHSA & IRC. Each industry & association standard implies assurance to quality. In this respect, it is the generally accepted practice of construction & materials handling, being addressed:

  • The Member builder shall designate an individual who has authority & responsibility to enforce the Quality Assurance Program, & in the case of a member Manufacturer, reports to a member of management who has responsibility extending beyond production.
  • A system of storage of materials & protection of the unit during the build must be in place to prevent damage from weather (i.e. heat/cold & moisture.)
  • NOAH Members will have the opportunity to offer “Best Practice” suggestions for inclusion in the developing list of quality assurance principles not readily or evidently expressed elsewhere for Structures.


7. NOAH Certification Seal

Each Structure is built by a NOAH Member, thereby meeting the requirements of the NOAH Standard Inspection Program. The inspected Structure is granted the right & privilege to display the NOAH Certification Seal. The NOAH Certification Seal is an external recognition of the builder’s commitment & compliance to the NOAH Standard, at the time of the initial build. Each individual NOAH Certification Seal is uniquely numbered & corresponds to the VIN or other Identifier of the Structure it is adhered to.


What Certification Represents...

  • The NOAH Certification Seal represents the builder's compliance with the NOAH Standard.
  • The NOAH Standard is a minimum requirement for certification, although builders may choose to exceed these standards.
  • The NOAH Standard incorporates safety & construction standards currently used by the Recreational Vehicle & Home Building industries; with particular attention to the unique demands of a Tiny House on Wheels by including the American Tiny House Association's Construction Guidelines (revised edition.)
  • A NOAH Certification Seal displayed on the tongue of the trailer provides a visible symbol & confirmation of THAT Tiny House on Wheels successfully completing the entire inspection process performed by NOAH inspectors.
  • NOAH Certification Seals are numbered & unique to each individual Tiny House on Wheels.
  • All elements of each inspection record (audio, video, .jpg, .doc, etc.) are archived by Certification Seal number, VIN number (or other identifier), Name of Builder (Manufacturer or Do-It-Yourselfer) for easy identification in the future.
  • Inspection Records are retrievable for review (by lenders, insurers, individual owners, municipalities, etc.) for compliance to future standards not currently in place at the time of the build.
  • NOAH Certification provides the unique distinction & credibility of a third-party inspection of EACH Tiny House on Wheels.



  • NOAH is an inspection company performing most inspections remotely
  • Inspections are performed by Licensed ICC and/or InterNACHI Certified Professional Inspector
  • All elements of each inspection record (audio, video, .jpg, .doc, etc.) are archived by Permit number, Address, Seal/Insignia/Mark, VIN (or other identifier) & Name of Builder for easy identification in the future.
  • What Inspection & Certification represents depends on home type (see home type chart)

In the case of Tiny Houses on Wheels inspected as RV’s the Builder certifies compliance with the Standard. NOAH a non-interested 3rd party, performs and stores inspections as additional evidence of compliance to the Standard.

  • The NOAH Standard is a minimum requirement for Certification, although builders may choose to exceed those standards.
  • A NOAH Seal displayed on the structure provides a visible symbol & confirmation of THAT Structure successfully completing the entire inspection process performed by NOAH inspectors.
  • NOAH Seals are numbered & unique to each individual Structure.

NOAH Inspection & Certification provides the unique distinction & credibility of a third-party inspection of EACH Structure.

  • NOAH Inspection & Certification is a partnership between the builder (Authority Having Jurisdiction, Manufacturer, DIYer, or Educational Institution) and NOAH's staff and inspectors to inspect and certify compliance with The NOAH Standard.
  • NOAH Does NOT Inspect and Certify Tiny Houses on Movable Foundations as Modular or Factory Built Homes.  Each state has its own requirements or process to obtain an Insignia for modular or factory built dwellings. States have not determined a specific, separate, approval process for tiny houses on movable foundations as dwelling units.
  • NOAH Inspection & Certification is not an unconditional approval of a builder, their product line(s) or particular model(s), manufacturing processes, business practices...



NOAH Inspection & Certification is a voluntary program for builders to demonstrate compliance with safety, structural & energy efficiency standards for consumer confidence in the product(s) they produce.

  • NOAH is not inspecting factory built or modular construction homes at this time.

NOAH has chosen to dedicate all of its efforts to supporting NOAH Members & Communities .

  • NOAH is not a government agency or agent.

NOAH is an independent corporation serving the Tiny House industry.  NOAH collaborates with government, municipalities & community developers to harmonize multiple standards of safety, structural & energy efficiency standards in an effort to meet the needs of the rapidly evolving industry.

  • NOAH Inspection & Certification does not guarantee lending approval, insurance coverage or placement of Structures.

NOAH Inspection & Certification guarantees the Structure bearing the NOAH Seal has successfully passed inspection at specific phases of construction for compliance to safety, structural & energy efficiency standards currently used by the Recreational Vehicle & Home Building industries.
