Building Codes, Full Text Copies of Building Codes

NFPA 4.3.1 code on air duct materials at InspectApedia.comThis section of this page provides downloadable PDF copies of various building codes & standards.

We also provide contact information for various building code & standard agencies. Some of these permit free online access to building codes in non-printable or non-downloadable versions and all of the code agencies permit purchase of copies of the codes they maintain.

Because various states or provinces also have adopted versions of the model codes, often a copy of these is available from the state or province at no charge.

Shown here, an excerpt from NFPA 90A covering the construction, installation, operation, and maintenance of air conditioning and ventilatino systems, including filters, ducts, and related equipment, [in order] to protect life and property from fire, smoke, and gases resulting from fire or conditiosn that have manifestations similar to fire.
