must be over the age of twenty-one years, of good moral character and, at the time of
applying for examination, shall have had, during the ten (10) years immediately
preceding his or her application, at least seven and one-half (7½) years or the equivalent
as indicated below and during such time a minimum of ten thousand five hundred
(10,500) hours or the equivalent as indicated below of satisfactory experience in the
installation, alteration and repair of wiring and appliances for electric light, heat and
power in or on buildings or comparable facilities. Except as otherwise provided below,
such satisfactory experience must have been obtained while under the direct supervision
of a licensed master electrician or special electrician or, with respect to experience
outside the city, under the direct supervision of an individual with comparable
qualifications as determined by the commissioner, and while in the employ of (i) a
master electrician business as defined herein, or (ii) an individual, a partnership or a
corporation owning, leasing or managing a building, buildings or parts thereof and
employing a special electrician to perform electrical work in or on specific buildings,
lots or parts thereof owned, leased or managed by such individual, corporation or
partnership, or (iii) an individual, a partnership or a corporation deemed acceptable by the
commissioner. No more than twenty-five percent ( 25 %) of such satisfactory experience
shall have been gained while working outside the United States unless the commissioner
determines that the licensing system and electrical code of the foreign jurisdiction is
essentially similar to licensing systems and electrical codes in the United States. The
following shall be deemed to fulfill the satisfactory experience requirement:
1. A journeyman electrician who has worked at least seven and one-half
(7½) years and during such time a minimum of ten thousand five hundred (10,500) hours
of such experience must have been obtained by working with his or her tools on the
installation, alteration and repair of wiring and appliances for light, heat and power in or
on buildings or comparable facilities, or
2. A graduate of a college or university who holds a degree in electrical
engineering, either a master of science (M.S.) or bachelor of science (B.S.) and has in
addition worked at least (i) with respect to an applicant with an M.S. degree, two and
one-half (2½) years and during such time a minimum of thirty-five hundred (3500) hours
of such experience or, (ii) with respect to an applicant with a B.S. degree, three and

hours of such experience must have been obtained by working with his or her tools on the
power in or on buildings or comparable facilities, or
3. A graduate of a vocational, industrial, trade school or apprenticeship
program, registered with the New York state department of labor, specializing in
electrical wiring, installation and design or applied electricity, who has worked at least
five and one-half (5½) years and during such time a minimum of seventy-seven hundred
(7700) hours of such experience must have been obtained by working with his or her
tools on the installation, alteration and repair of wiring and appliances for electric light,
heat and power in or on buildings or comparable facilities, or

degree in electrical engineering, mechanical engineering, bachelor of science in electrical
engineering or mechanical engineering, who passed all subjects in the required courses
shall be credited with satisfactory experience equal to fifty per cent (50%) of the number
of curricula years he or she has satisfactorily completed which, in no event, however,
shall exceed two and one-half (2½) years credit of satisfactory experience, the balance of
the required seven and one-half (7½) years, i.e., five (5) years and during such time a
minimum of seven thousand (7000) hours of such experience must have been obtained by
working with his or her tools on the installation, alteration and repair of wiring and
apparatus for light, heat and power in or on buildings or comparable facilities, or
5. Any person who attended courses in a vocational, industrial or trade
school, registered with the New York state department of labor, specializing in electrical
wiring, installation and design or applied electricity who has passed all subjects in the
required courses shall be credited with fifty per cent (50%) of the number of curricula
years that he or she has satisfactorily completed which, however, in no event, shall
exceed two (2) years credit of [practical] such experience, the balance of the required
seven and one-half (7½) years, i.e., five and one-half (5½) years of such experience and
during such time a minimum of seven thousand (7000) hours must have been obtained by
working with his or her tools on the installation and repair of wiring for electric light,
6. An employee of a government agency, private inspection agency or
other entity, acceptable to the commissioner, whose duties primarily involve the
inspection of electrical work for compliance with the electrical code and the electrical
code technical standards and/or other laws relating to the installation, alteration or repair
of electrical wiring or appliances shall be credited with fifty percent (50%) of the
number of years that he or she has been satisfactorily employed in such duties within the
ten (10) year period prior to application, which, however, in no event, shall exceed two
and one-half (2 ½) years credit of satisfactory experience. The balance of the required
seven and one-half (7 ½) years, i.e., five (5) years and during such time a minimum of
seven thousand (7000) hours of such experience must have been obtained by working
with his or her tools on the installation, alteration and repair of wiring and appliances for
electric light, heat and power in or on buildings or comparable facilities except that the
requirement of subdivision a of this section that an applicant’s working experience must
have been within the ten (10) year period prior to application shall not apply to such
balance of five (5) years working experience required pursuant to this paragraph.
c. Every applicant shall be required to take an examination in accordance
with the rules of the department. However, where the application is on behalf of a city
agency, the commissioner may waive the examination requirement if the applicant has
sufficient experience qualifications, as determined by the commissioner.
§2. Subdivision a of section 27-3015 of the administrative code of the city

examination, provided application for such renewal, accompanied by the renewal fees
prescribed above and such information as may be required by the commissioner to ensure
compliance with section 27-3016 of this chapter, shall have been filed prior to the
expiration of the existing license. Where an applicant can show good and sufficient cause
for his or her inability to renew his or her license and seal before its expiration, the
commissioner may, within thirty days after the expiration of such license, permit the
issuance, without examination, of a new license and seal upon payment of the prescribed
fees for such new license and seal within said thirty days. No license shall be renewed
and no new license and seal shall be issued unless all outstanding fees required by section
27-3018 of this code have been paid. The commissioner may promulgate rules requiring
applicants for the renewal of master or special electrician’s licenses to submit proof, in
such form as he or she shall determine, that, in each year of the license term, such
applicant completed at least ten hours of continuing education courses approved by the
department. Such proof shall be submitted not less than two months prior to the

approved such application and issued an appropriate permit for such work. The permit
shall be conspicuously posted at the work site at all times while the work is in progress.
Each permit shall be issued with an expiration date to be determined in accordance with
the rules of the department, but not less than one year after the date of issuance. An
