About this classification

What does a C-61 Limited Specialty contractor do?

A C-61 Limited Specialty Contractor performs specialty work for which the applicant is qualified that falls outside any of the defined specialty (C) classifications. Each C-61 license is confined to a specific field, a D-subclassification, that the CSLB Registrar endorses.

Under the California Code of Regulations (Title 16, §832.61), the C-61 covers specialty contracting "for which an applicant is qualified other than any of the specialty…classifications listed and defined in this article." Rather than one broad scope, the C-61 is a family of narrow D-subclassifications, each limited to a single field of work. Other specialty contractors may perform C-61 work when it is consistent with their own classification.

  • California requires a license for any specialty contract over $1,000 (labor and materials combined), and workers' compensation coverage is required once you have employees; sole owners with no employees may file an exemption (BPC §7125(b)).

Common Questions

C-61 Limited Specialty license FAQ

The C-61 is California's umbrella classification for skilled trades that do not fit any defined C classification. Instead of one broad scope, each C-61 license is issued as a specific D-subclassification, such as D-35 Pool & Spa Maintenance or D-65 Weatherization, that the CSLB Registrar endorses based on your qualifications. There are 29 active D-codes.
If your trade matches a defined C classification, you must apply for that classification, the C-61 is only for specialty work that falls outside every defined C class. For example, electrical work is C-10 and landscaping is C-27, so neither uses the C-61. The C-61 covers narrow trades like awnings, window coverings, or pool maintenance that have no standalone C class.
There are 29 active D-subclassifications, including D-3 Awnings, D-4 Central Vacuum, D-6 Concrete-Related Services, D-12 Synthetic Products, D-16 Hardware/Locks/Safes, D-21 Machinery & Pumps, D-28 Doors/Gates/Activating Devices, D-30 Pile Driving, D-34 Prefabricated Equipment, D-35 Pool & Spa Maintenance, D-38 Sand & Water Blasting, D-39 Scaffolding, D-41 Siding & Decking, D-50 Suspended Ceilings, D-52 Window Coverings, D-63 Construction Clean-up, and D-65 Weatherization, among others.
Over the years, some D-codes were absorbed into newer, standalone C classifications as those trades grew large enough to warrant their own license. The C-61 still holds the trades that have not been promoted to a standalone C class (check with CSLB for the current status of any specific D-code), since some (like D-49) remain active and separate from a similarly-named C classification.
Most students are exam-ready in 4–6 weeks of CSLS prep. Adding CSLB application processing (typically 2–4 weeks), exam scheduling, and posting your $25,000 bond, the full path usually runs 2–4 months from start to license-in-hand.
No. Business and Professions Code §7065.01 states that C-61 Limited Specialty applicants do not take a trade exam. Applicants still take the Law & Business exam unless they qualify for an examination waiver.
