This is a catch-all classification for very limited trades, that is, very few contractors engage in these trades. Examples of C-61 sub-classes are Gutter Installation, Safes and Vaults, Sand and Water Blasting, etc. The California Contractors State License Board describes the C-61 – Limited Specialty Classification License as:
(a) Limited specialty is a specialty contractor classification limited to a field and scope of operations of specialty contracting for which an applicant is qualified other than any of the specialty contractor classifications listed and defined in this article.
(b) An applicant classified and licensed in the classification Limited Specialty shall confine activities as a contractor to that field or fields and scope of operations set forth in the application and accepted by the Registrar or to that permitted by Section 831.
(c) Upon issuance of a C-61 license, the Registrar shall endorse upon the face of the original license certificate the field and scope of operations in which the licensee has demonstrated qualifications.
(d) A specialty contractor, other than a C-61 contractor, may perform work within the field and scope of the operations of Classification C-61, provided the work is consistent with established usage and procedure in the construction industry and is related to the specialty contractor’s classification.
The CSLB has listed the C-61 classifications into “D” subcategories for administrative tracking. The definitions for the “D” subcategories were developed by staff and approved by the Board as policy.
