Plan Review and Approval Process

Before beginning construction of any buildings to be installed in Arizona, a manufacturer shall submit a Compliance Control Manual and Building plans for review and approval. Upon approval of submitted documents, a new manufacturer may initiate the certification process, or a previously certified manufacturer may begin construction of the approved building. See the inspection section for certification and inspection requirements.

Manufacturer Certification

Manufacturer certification is an evaluation function. A certification has two primary purposes. • To verify that the manufacturer is capable of producing modules that comply with the law and the rules, mandatory building codes and approved plan designs. • To verify that the manufacturer's approved compliance control program will ensure compliance now and in the future. A manufacturer with multiple production facilities shall have each facility that will be producing units for Arizona-certified. Each manufacturer shall have an approved compliance control manual for a specific facility and approved plans to build it. Any/all modules shipped to or within Arizona shall be produced in a certified facility.

FBB Continuing In-Plant Inspection

After certification, inspections of the manufacturing facility are performed to ensure that:

The manufacturer continues to follow their approved compliance control procedures.
The manufacturer continues to produce units that conform to the approved designs and codes in effect at the time of inspection.
Corrections are made if an inspection reveals non-compliance.
When non-compliance to the approved design is discovered in one unit, other related units do not leave the facility with the same non-compliance.
When the non-compliance is related to life safety, the manufacturer and OMH are notified so that the preceding units may be corrected.
The approved compliance control procedures prevent the covering of non-compliances prior to corrections.

Installation and Site Inspection Process

The installation of Factory Built Buildings shall be inspected by ADOH or other government entities in agreement with ADOH.

Installation inspections of factory built buildings are performed to ensure:

Completion and attachment are in accordance with mandatory building codes, the approved design package and on-site construction documentation.
Completion and attachment in accordance with the foundation system design and unique on-site details that have been sealed by a registered Arizona engineer.
All tests required by approved on-site documentation, Arizona installation standards, and mandatory building codes are performed.

Reporting Requirements

INSTALLERS - A monthly report is due by the 15th of each month for the previous month's usage, from the 1st through the 31st, etc. Please note that a separate report shall be filed for each month. Please do not combine multiple months on the same report. As long as an installer has insignia in possession, whether any were actually used or not for the month, a report is still required. If no certificates were used, then report no insignia were used. If an installer has no insignia in possession, then a report is not required.

MANUFACTURERS - Manufacturers are required to submit the Manufacturer’s Insignia Report monthly by the 15th of each month. A report shall be submitted even if no modules were built for Arizona. Please note that a separate report shall be filed for each month. Please do not combine multiple months on the same report. As long as a manufacturer has previously issued insignia or the new Modular Certificates in possession, whether any were actually used or not for the month, a report is still required. If no insignia or certificates were used, then report "no insignia or certificates" were used.

In-State Factory Built Building Certification and Inspection Requirements

MANUFACTURER CERTIFICATION

Manufacturer certification is an evaluation function. A certification has two primary purposes.

To verify that the manufacturer is capable of producing modules that comply with the law and the rules, mandatory building codes and approved design package.
To verify that the manufacturer's approved compliance control program will ensure compliance now and in the future.

A manufacturer with multiple production facilities shall have each facility that will be producing units Arizona-certified. Each facility shall have a design package, compliance control manual, and building plans approved for that specific facility.

Any/all modules shipped to or within Arizona shall be produced in a certified facility.

PRE-CERTIFICATION INSPECTION REQUIREMENTS

The manufacturer's design package, compliance control manual and building plans for the building to be used as the certification example shall be submitted to the Arizona Department of Housing (ADOH) for review and approval prior to the beginning of the certification process. These approved documents must be available at the manufacturing facility during the certification inspection.
The manufacturer must coordinate schedules with ADOH to conduct the certification inspection of the manufacturing facility, manufacturing process, and compliance control process. The manufacturer shall be invoiced for travel and time expended during the conduct of the certification inspection.

CERTIFICATION INSPECTION REQUIREMENTS

The certification inspector shall spend as much time as necessary in the manufacturing facility to ensure that all aspects of the compliance control program are functioning according to the manufacturer's approved procedures. At least one module containing all systems, or a combination of modules containing all systems, shall be observed during all phases of construction in the facility. The certification inspector shall inspect all units in production for Arizona during the course of the certification inspection. Similar units in production for other states may be inspected as an aid in the evaluation of the facility.

All non-compliance shall be resolved to the satisfaction of the certification inspector prior to certification of, or release of insignia to, the manufacturer. Corrective actions taken to resolve non-compliance shall be inspected by the certification inspector. Revisions to plans, design package, or compliance control manual taken to correct non-compliance shall be reviewed and approved by ADOH prior to acceptance by the certification inspector.

Certification Inspection Process Outline

The manufacturer shall provide copies of the approved design package, building plans, compliance control manual and a suitable location in which to work during the duration of the certification inspection. The certification inspector will review in detail, and become familiar with the approved documents.
The certification inspector shall inspect all phases of construction for compliance to the approved design package and to the mandatory building codes, and to assure that the manufacturer is following the approved compliance control procedures.
The certification inspector shall witness system testing on one or more modules. All types of system tests must be observed. Failure of a system test is not non-compliance. Failure to take action to correct the cause of the failure of the system test is non-compliance and shall be documented as such. Failure to follow the approved procedures for performing the system test shall be documented as non-compliance.
The certification inspector shall allow the manufacturer's compliance control personnel the opportunity to inspect and discover non-compliance to the approved design package or to the mandatory building codes in accordance with the procedures outlined in the manufacturer's compliance control manual. Non-compliance noted by the certification inspector shall be brought to the attention of the designated manufacturer personnel after inspection by manufacturer personnel but prior to the construction being covered in the normal process of construction. Failure of the manufacturer's compliance control personnel to identify and initiate corrective action for non-compliance shall be documented as a failure of the manufacturer's compliance control program. Repetitive non-compliance or failure to follow approved procedures may require changes in the manufacturer's compliance control procedures.
The certification inspection shall conclude when all phases of construction and all system testing have been witnessed by the certification inspector, upon verification that all corrective actions on the certification units have been completed, and when enough data has been collected to fully evaluate all aspects of the manufacturing facility and process.

POST-CERTIFICATION INSPECTION REQUIREMENTS

A certification report shall be issued by ADOH to the manufacturer when all certification requirements have successfully been met. The manufacturer and ADOH shall retain a copy of this report for their records. The certification report shall include the following:

The name and facility address of the manufacturer.
The names and titles of key manufacturer personnel and any/all certification inspectors involved in the certification inspection process.
The initial approval date of the manufacturer's design package, compliance control manual, and building plans.
The serial or identification number of all modules inspected during the certification inspection.
A description of any/all non-compliance discovered and corrective actions initiated during the course of the certification inspection.
A description of the type of building system inspected (wood frame, steel, concrete, etc.).
A statement by OMH that all requirements for certification have been met to the satisfaction of OMH and that the facility is considered certified for continuing production for the State of Arizona.

Certificate Insignia

Upon successful completion of the certification process and receipt by ADOH of the certification report, the manufacturer may order and affix Arizona insignia to completed modules. Insignia containing the complete plan approval and serial number may be affixed only to modules that are complete to the factory's scope of work and ready to ship. The date that the insignia is affixed to the module will be considered the date of manufacture. No module shall be shipped to or within the State of Arizona without having an AZ insignia affixed. Each module shall have an Arizona insignia affixed; this means if a building consists of seven modules, then seven insignia shall be affixed to that building.

Conditions for Continuing Certification

Once a manufacturer has successfully completed the certification process, the following conditions must be met to maintain that certification as valid:

After certification, the first module with any type of construction other than that described in the certification report shall require 100% inspection of that construction by ADOH. This inspection is in addition to the normal in plant inspection required by the FBB In-Plant Inspection Process. Any modifications or additions to the compliance control manual must be submitted for approval prior to beginning construction. A report of the successful completion of this inspection shall be provided by ADOH and considered as an update to the manufacturer's certification, allowing further production of the new construction type for Arizona.
A manufacturer shall comply with the requirements of the FBB In-Plant Inspection Process.
All reporting requirements must be maintained and up to date. (Inspection reports, insignia assignment, etc.)
A certification shall remain valid for six months from the date of manufacture of the last module manufactured for Arizona. If a manufacturer does not manufacture a module for Arizona for six months, then their certification will be considered expired. Further production for Arizona shall require re-certification.

FBB Continuing IN-PLANT Inspection

After certification, inspections of the manufacturing facility are performed to ensure that:

The manufacturer continues to follow their approved compliance control procedures.
The manufacturer continues to produce units that conform to the approved designs and codes in effect at the time of inspection.
The units produced conform to the approved designs contained in the design package.
Corrections are made if an inspection reveals non-compliance.
When non-compliance to the approved design is discovered in one unit, other related units do not leave the facility with the same non-compliance.
When the nature of the non-compliance is related to life safety, the manufacturer and OMH are notified so that the preceding units may be corrected.
The approved compliance control procedures prevent the covering of non-compliances prior to corrections.

Frequency of Inspections

The Arizona Department of Housing (ADOH) may conduct announced and unannounced inspections at the manufacturing facility at reasonable but varying intervals to review any and all aspects of the manufacturer's production and compliance control program.
The frequency of inspections may be increased if a review of the last five inspection reports indicates two or more failures of the compliance control personnel to follow their approved procedures. The increased frequency of inspections may continue and insignias may be taken under the control of ADOH until the agency is satisfied that the problem has been corrected.
The frequency of inspections may be increased if a review of the last ten inspection reports indicates the failure of the manufacturer to provide an approved design for a unit or units on two or more inspections. The increased frequency of inspections may continue and insignias may be taken under the control of ADOH until the agency is satisfied that the problem has been corrected.
The frequency of inspections may be increased if a review of compliance control travelers for units that received an Arizona insignia since the last inspection displays a failure of the compliance control staff to document inspections in accordance with the manufacturer's approved procedures. The increased frequency of inspections may continue and insignias may be taken under the control of ADOH until the agency is satisfied that the problem has been corrected.

Inspection Procedures

Inspection procedures are applicable to all in-plant inspections, including re-inspections.

The inspector shall perform an entrance interview at the start of the inspection. During the interview, the inspector shall inform the manufacturer:
a. that the compliance control procedures must function normally as stated in the approved compliance control manual;
b. that the compliance control documents (travelers) will be examined for all units that received an insignia since the last inspection;
c. that every Arizona unit in the production process will be inspected. This may include units previously inspected;
d. system testing must be witnessed at least once every third inspection.
The inspector shall request notification of changes to the approved design package and review the manufacturer's design package before beginning the inspection. The inspector shall also review the inspection reports from the last ten inspections and document uncorrected non-compliances on the present inspection report.
The inspector shall inspect all visible aspects of every Arizona unit in the production process.
Non-compliance shall be recorded on the in-plant inspection report. Non-compliance identified and corrected by the manufacturer's production or compliance personnel need not be recorded.
The inspector may not inform the manufacturer of non-compliance on the units until the manufacturer's compliance control personnel have completed their inspections unless the non-compliance is about to be covered by other construction or if the inspector has completed the inspection and the non-compliance will not be corrected before he/she leaves the plant.
If non-compliance is discovered in a unit, then all Arizona units in production shall be inspected for the same non-compliance.
Failure of the compliance control personnel to perform their required inspections prior to the construction being covered shall be documented as non-compliance.
Failure of the compliance control personnel to follow their approved procedures shall be documented as a non-compliance.
If the approved design package is not specific with respect to some aspect of construction or the manufacturer does not have an approved design for a unit or units, then the inspector shall not inspect until the manufacturer can produce the necessary approvals. Lack of approved documents shall be recorded as non-compliance on the inspection report. Construction concealing the aspect of construction that could not be inspected shall be uncovered to facilitate inspection at a later date.
The inspector may review the compliance control travelers for units that have received an insignia since the last inspection. Inadequate or incomplete compliance control travelers shall be recorded as non-compliant on the inspection report.
The inspector shall conduct an exit interview at the completion of the inspection to discuss the inspection relative to non-compliance, corrective actions, and any compliance control problems that need to be corrected. If necessary, Arizona insignias will be confiscated at this time and shall not be returned until the manufacturer can demonstrate to OMH that all non-compliance has been brought into compliance.

Inspection Report

ADOH shall compile a report of each in-plant inspection. The manufacturer shall retain copies for a minimum of five years. Each report shall include the following:

The unit serial number for each module inspected.
