Architectural Coatings are coatings applied to stationary sources and their appurtenances, to portable buildings, to pavements, or to curbs. Appurtenances are accessories to an architectural structure, including, but not limited to: handrailings, cabinets, bathroom and kitchen fixtures, fences, decks, rain gutters and downspouts, window screens, lamp posts, signs, concrete forms, heating and air conditioning equipment large fixed stationary tools, and other mechanical equipment.

Beginning in the mid-1970s, the Air Resources Board (ARB) and the districts began developing source specific rules such as rules for individual coating sources like architectural coatings. In those districts that have not adopted a source specific coating rule like architectural coatings, the national architectural coating rule applies. Over the ensuing years, rules were developed that cover a multitude of coating operations such as aerospace, architectural coatings, metal parts and products, and automotive painting. Most districts now have rules covering one or more of these categories.

The rules in each district are dynamic and subject to change. The ARB recommends that if you want specific information on a particular rule to contact the district. Ask the district to place your name on their mail list so you will be notified when a rule is amended. Although the ARB promotes and encourages uniformity among rules in each district, due to the unique air pollution problems in each district, rules may be tailored to meet these conditions for each district. Hence, adjacent districts may have different rules. The state of California is subdivided into 58 counties, 14 air basins, and 35 local districts.

To ensure compliance with district regulations / rules, businesses who perform coating activities or provide coatings for use in one or more areas of California should contact the local district in each area that a facility is located or the coating will be used. The district(s) can help you identify any requirements that may exist. The regulations / rules that have been adopted in each district apply only to the geographic boundaries of the district. For your convenience a district contact list is available from this web page.
