Rule 4. Factory-Built Residential Structures (Modular and Tiny Homes) and Non-Residential Structures (Commercial) Requirements 4.1 Every “factory-built structure” as defined in section 24-32-3302(11), C.R.S., that is manufactured, sold, offered for sale, or occupied in this state must display an insignia issued by the Division of Housing certifying that the structure is constructed in compliance with the codes adopted by the State Housing Board. This does not apply to factory-built structures manufactured or sold for transportation to and installation in another state. However, if the unit were to return to Colorado for use, then it would require an insignia issued by the Division of Housing. To assist with the certification process, pursuant to section 24-32- 3303(1)(a), C.R.S., a “manufacturer” as defined in section 24-32-3302(23), C.R.S., is required to be “registered” (based on qualifications) or “certified” (based on performance) with the Division of Housing.
4.1.1 Registration or certification is for a specific manufacturing facility location, and is not transferable to any other location including those of the same manufacturer.
4.1.2 A registered or certified manufacturer is required to inform the Division of Housing of a change in ownership, address, or location within ten (10) business days of such change.

4.2 Registered/Certified manufacturers are required to have that facility’s production approved through an initial review of its Quality Control (QC) program and the Quality control personnel that ensure construction code compliance. The Division of Housing must be notified of any changes to the QC program or personnel.
4.3 The manufacturer’s QC department must perform “no cover” inspections for all phases of construction on all structures and witness all required tests, regardless of whether the facility is registered or certified.
4.4 Upon the manufacturer’s receipt of the approved plans and manual, the third
party agency may proceed with QA, rough, and final inspections with registered manufacturers, or if the manufacturer is certified, to include factory oversight inspections.
4.5 Manufacturers who sell direct to purchasers of one or two family dwellings must register as a Seller with the Division of Housing and follow all statutory and Administrative Rules requirements. See Rule 5.
4.5.1 The exception is if the purchaser is a developer who in turn plans to resell the home to the end-user; the developer in that scenario is required to be a registered seller with the Division of Housing.
4.5.2 Manufacturers who receive down payments or deposits from registered
4.6 In order to provide efficiency, manufacturers building multi-family or commercial units as a part of a development project of 5 or more units must contact the Division of Housing and provide a project plan that includes: project schedule, production schedule, on-site construction items, and installation plan and schedule. It is recommended to contact the Division of Housing early in the plan process, even before all the required documents are available. The Division will evaluate the materials provided, meet with the respective parties, and determine a total estimated fee schedule. Overnight stays by inspectors may require additional expenses. Following the installation, it is recommended that a follow up meeting be conducted with all applicable parties to check the status of the project plan.
Manufacturer Registration 4.7 Once issued by the Division of Housing’s Building Codes & Standards Section, a registration is active for one (1) year or three (3) years after completing the first year and must be successfully renewed in order to continue manufacturing structures in the state of Colorado or shipping them into the state. Three year registrations will require an email or letter regarding any material changes (or no changes) to operations annually. For three year registrations, it is the responsibility of the manufacturer to ensure annual payment is paid in a timely manner or forfeit the remaining registration period. Notifications are only sent as a courtesy, for all registration types, when the Registration period is going to expire at 60 days and 30 days prior to the expiration date and when it expires.
4.8 At the time of registration, all manufacturers are required to have Division of Housing approval, in writing, of the third party agency or agencies that will conduct the production inspections and certification of Colorado units on behalf of the Division of Housing. A manufacturer is also required to request approval of the Division of Housing thirty (30) days prior to any subsequent change of its third party agency.
Certified Manufacturer Status
4.9 A manufacturer must maintain an active Colorado registration for each
manufacturing facility requesting Certified status.
4.9.1 Out of state registered manufacturers must utilize a third party agency to submit a recommendation for certified manufacturer status to the Division of Housing.
4.9.2 In-state registered manufactures may utilize a third party agency to submit a certified manufacturer recommendation OR request certified manufacturer status from the Division of Housing.
4.9.3 Each manufacturing location will require a separate certified manufacturer recommendation.
4.9.4 The Division of Housing and authorized third party agencies will utilize the following criteria for approval of registered manufacturers requesting certified manufacturer status.
4.9.5 Manufactures who previously qualified for the Division of Housing’s
4.9.6 Recommendations received from a third party agency will be reviewed,
4.10 All certified manufacturers are registered manufacturers and must follow all registered manufacturer requirements unless specifically exempted or changed in these rules.
4.11 Certified manufacturer status for a specific facility is considered ongoing unless the manufacturer fails to perform as described in 4.12. An annual letter will be required from the manufacturer regarding any changes, or stating no changes, in the quality assurance program in order to continue certified manufacturer status.
4.12 The Division of Housing may immediately seek summary suspension to remove
the designation of certified manufacturer status for failure to remedy any of the following conditions after notice from the Division of Housing:
4.12.1 The change of a third party agency or change in that entity’s status.
4.12.2 The change of a facility location.
4.12.3 The manufacturer has had insignias of approval removed pursuant to
4.12.4 Failure to remedy manufacturing defects or deficiencies as identified by
4.12.5 Notification by a third party agency regarding failure to meet quality control guidelines.
4.12.6 The factory is not in compliance with “Performance Criteria for Monitoring Manufacturers and Third Party Inspection Agencies”.
4.13 A registered manufacturer whose status as a certified manufacturer has been removed by the Division of Housing will resume operations on a higher frequency of inspections until its performance improves and is recommended for reinstatement of its certified manufacturer status pursuant to Rule 4.9 of these rules.
Renewal 4.14 Each manufacturer is required to resubmit its quality control manual (and when applicable, plans) for approval prior to the registration expiration date that is stamped on the quality control manual. This Quality Control manual resubmission is required regardless of when plans are approved or structures shipped. Failure to comply with this requirement will result in that manufacturer’s registered location having to comply with the initial registration inspection requirements.
4.14.1 The registration expiration date for all manufacturers is determined by the expiration date that is stamped on the quality control manual. Plans that are submitted at the time of registration or within the registration period shall have the same expiration date as the quality control manual.
4.14.2 It is the responsibility of the manufacturer to submit to the Division of Housing the quality control manual for approval within the authorized sixty
Plan Review 4.15 All registered or certified manufacturers must obtain prior approval of each set of designs from the Division of Housing or third party agency before constructing structures under those plans.
4.15.1 The Division of Housing will expedite the review and approval of plans
4.15.2 Life safety corrections will be sent back to the manufacturer and the third party agency that pre-approved the plans. Third party agencies who continue to pre-approve plans after notification of life safety plan corrections must provide a report on internal quality assurance corrective actions taken to the Division of Housing.
4.15.3 The Division of Housing and third party agencies will utilize redline
4.16 Plan approvals are granted to a manufacturer for a specific manufacturing facility and are not transferable to other manufacturing facilities including those of the same manufacturer.

4.18.1 Expired applications must be resubmitted as new applications
4.19 In order to be considered approved, plans and quality control manuals must be stamped by the Division of Housing or third party agency. Revisions, additions, or deletions will not be acceptable without prior approval.
4.19.1 An approved copy of the quality control manual and plan must be retained
4.19.2 All third party agency approvals must be submitted to the Division of
4.20 Plan approval does not guarantee a manufactured structure constructed from the approved plan will also be approved. All structures must also undergo an inspection and receive an insignia of approval in order to be considered certified by the State of Colorado. A plan approval does not prevent the Division of Housing or the third party agency from requiring the correction of errors found in the plans or the unit itself, when found in violation of these rules.
4.21 Revisions to the approved plan are required where the manufacturer proposes a change in structural, plumbing, heating, electrical, or fire life safety systems. Such changes must become part of the approved plan unless the Division of Housing determines that the change constitutes a new model. If determined a new model, the interim change will be processed as a new application. Any difference in fees will also be assessed.
4.22 The Division of Housing will approve unchanged plan renewals it previously
reviewed and approved, provided there has been no change in adopted codes and the manufacturer’s officer in Rule 4.17.2 above certifies in writing that the plans are identical to those previously approved by the Division of Housing. A “Supplemental Plan Check Fee” will apply for plan renewals.
4.22.1 Should it be determined by the Division of Housing that unauthorized
4.23 When amendments to these regulations require changes to be made to an
approved plan, the Division of Housing will notify the manufacturer of the requirement and allow it a reasonable time to submit revised plans for review and approval. Revised plans will be processed as interim changes with the appropriate fees assessed.
4.24 Approved plans expire with the factory registration. Plans must be resubmitted and the Supplemental Plan Check Fee will apply. New plans approved within 120 days of the manufacturers’ registration expiration date will not be required to resubmit plans for renewal until the next registration cycle. If the manufacturer fails to register on time, due to fault of their own, those plans are no longer valid and will be required to be renewed. The asset for that structure is required to have been created and construction started before the expiration to be exempt from the renewal process for that specific plan and structure.
4.25 Tiny home plans must include: details on the vehicle chassis, including drawings and connections, and whether the tiny home is going to be installed on a permanent or temporary foundation.
Inspections 4.26 All structures manufactured, sold, or offered for sale in the state of Colorado must display the Division of Housing insignia of approval affixed either by the Division of Housing, an authorized third party agency, or by a certified manufacturer. These insignias certify that the unit is constructed in compliance with applicable codes and regulations adopted by the State Housing Board. This does not apply to factory-built structures or tiny homes manufactured or sold for transportation to and installation in another state. However, if the unit were to return to Colorado for use, then it would require an insignia issued by the Division of Housing.
4.26.1 Registered (non-certified) and certified manufacturers must apply for
additional insignias of approval to a third party agency or certified manufacturer if all insignias affixed are not timely and completely reported.
4.27.2 Insignias are assigned for use at a specific location and cannot be

4.27.6 For installation and inspection insignias, the name of the installer or
4.28 Whenever an on-site inspection reveals that a structure fails to comply with any provision of these rules, the Division of Housing or the third party agency may affix a “Red Tag Notice” on the structure. All manufacturers must correct any construction code violations within thirty (30) calendar days of inspection. Life safety corrections may require less than 30 days to correct. An extension may be granted when submitted in writing to the Division of Housing.
4.28.1 Once notified of a “Red Tag Notice” by the Division of Housing or the third party agency and the specific violation(s), the affected parties must resolve the issue(s) with the entity that posted the notice.
4.28.2 Within five (5) working days, the affected parties or their agents must

4.28.4 All structures posted with a “Red Tag Notice” must be corrected or
4.28.5 A “Red Tag Notice” may be removed only by an authorized representative
4.29 Factory-built structures may not be modified, prior to or during, installation at a site without approval from the Division of Housing. Once installed and its installation certified (factory-built residential structures only), any substantial alternation or repair made to the construction of the structure (both residential and nonresidential) already certified by the Division of Housing and on-site is under the jurisdiction of the local building department.
4.30 The Division of Housing and/or the third party agency retained by the
manufacturer will conduct certification and production inspections of all manufacturers engaged in manufacturing or offering for sale factory-built structures in the state of Colorado. This inspection will include the quality control program and systems testing. This does not apply to factory-built structures manufactured or sold for transportation to and installation in another state. However, if the unit were to return to Colorado for use, then it would require an insignia issued by the Division of Housing.
4.30.1 Payment of the fees provided in Rule 3 is required if utilizing the services of an inspector from the Division of Housing. This cost is not refundable.
4.30.2 All in-state manufacturers shall have the option to contract with a third party agency or continue to use the Division of Housing to perform certifications and in-plant production inspections, to evaluate its registered/certified location’s Quality Control procedures, approve manufacturer engineering manuals and installation instructions and/or approve construction plans.
4.30.3 Out of state manufacturers are required to obtain the services of a third party inspection agency to perform certifications and in-plant production inspections, to evaluate the plant’s Quality Control procedures, and may use an approved third party agency to approve manufacturer engineering manuals, installation instructions, and/or approve construction plans.
4.31 A third party agency may consist of one of the following entities (any exceptions must have prior approval by the Division of Housing):
(A) States – must enter into a memorandum of understanding with Colorado.
(B) Local Government – must adopt Division-approved local ordinance or rule.
(C) Firms – must currently be listed with a national listing agency such as the International Code Council (ICC), International Accreditation Service (IAS), or other Division-approved entity.
4.32 Other states that wish to operate as a third party agency inspecting
registered/certified manufacturers located in their state and structures manufactured in their state that are to be shipped to Colorado must have existing statutory authority to regulate the design and construction of factory-built structures and enter into a memorandum of understanding with Colorado to establish recognition of the following:
(A) Acceptance of construction codes that are adopted by the State of Colorado Housing Board for factory-built structures sold into or offered for sale in Colorado. (See Rule 2 of these rules).
(B) Acceptance of the design evaluation and approval performed by the Division of Housing or other third party agency for structures sold into or offered for sale in Colorado.
(C) Performance of facility certifications and other inspection requirements. Routine inspections include performing inspections of at least one (1) unit in each phase of manufacturing and performing a minimum of a rough, final, and other inspections and/or tests (as required in Rule 2 of these rules) when a production line process is not being utilized. Also to place the manufacturer on a higher frequency of inspection when it is unable to conform, on a continuing basis, to approved Quality Control procedures and or approved plans and standards.
(D) Evaluation, at the manufacturing facility, of code compliance problems resulting from consumer complaints on labeled Colorado structures; work with the manufacturer(s) in resolving such complaints by adequately following up and assisting them in correcting the complaint issue(s), and their production and/or inspection process.
(E) Provide sixty (60) days notice before withdrawing from the memorandum of understanding, thereby allowing a manufacturer sufficient time to obtain a new third party agency.
4.33 Manufacturers contracted with a firm to perform its inspections are required to be inspected by that entity. A manufacturer may contract with more than one approved third party agency to perform these services. If more than one third party agency is under contract, the Division of Housing must be notified as to which inspections each agency is assigned; more than one agency cannot be assigned to the same inspection.
4.33.1 Approved third party agencies are authorized to conduct certifications, in- plant production inspections, recommend certified manufacturer status, in- plant evaluations of the plant’s quality control procedures, review manufacturer engineering manuals, approve plant construction plans, or perform on-site construction (OC) field inspections, in accordance with Division of Housing approved procedures and documents.
4.33.2 The structure will be inspected to the approved plans; except where the
4.33.3 A third party agency, when a facility is not certified, must conduct at a minimum a rough, final, and other inspections as required per code (see Rule 2 of these rules) for all structures manufactured. For tiny homes, a vehicle chassis inspection must be completed.
4.33.4 After the Division approves certified status for a manufacturer based on
4.33.5 Whenever the third party agency finds that a manufacturer is unwilling or unable to conform on a continuing basis to the approved quality control procedures, or approved plans or standards, that manufacturing facility will be placed on a higher frequency of inspection. The Division of Housing must be notified and the certification labels for units held until the manufacturer demonstrates that it can perform within its approved standards. If after three (3) consecutive inspections, the last inspection still indicates that the manufacturer is not able to perform within standards, all remaining insignias paid for by the manufacturer will be returned to the Division of Housing and the manufacturer will need to reapply for certified status after the time period in 8.1.1.
4.33.6 Additional information, such as increased frequency and routine quality
4.33.7 The third party agency is required to provide its own inspection label to be affixed adjacent to the Colorado insignia of approval on each structure to be installed in Colorado prior to shipping.
4.33.8 All manufacturers that use a third party agency, other than another state, to perform production inspections, recommendations for certified manufacturer status, evaluate quality control procedures, approve engineering manuals, or approve plans, must have such agency request approval from the Division of Housing to be an approved third party agency for the State of Colorado.
