Garage door rules in Haddon Heights, NJ

New Jersey Division of Consumer Affairs, Office of Consumer Protection, Regulated Business Section (Office of the Attorney General) — official site

There is no garage-door trade licence and no state contractor classification system. Instead, under the New Jersey Contractor's Registration Act, "Every business engaging in the business of making or selling home improvements, whether an individually owned business or a corporation, limited liability company, partnership, or other business entity, is required to register annually with the New Jersey Division of Consumer Affairs" unless specifically exempted, and must display its registration number (NJHIC#). Municipalities are barred from issuing construction permits to a contractor that is required to be registered and is not.

Registration requires "Proof of commercial general liability insurance in a minimum amount of $500,000 per occurrence." (The registration application package requires an insurance certificate naming the applicant as insured under a commercial general liability policy of at least $500,000 per occurrence.)

Under the NJ Uniform Construction Code, N.J.A.C. 5:23-2.7, "The replacement of any window or door, including garage doors, in the same opening without altering the dimensions or framing of the original opening" is ordinary maintenance, and "Ordinary maintenance to structures may be made without filing a permit application with or giving notice to the construction official." Ordinary maintenance does NOT include cutting away any loadbearing wall, removing or cutting any structural beam or bearing support, or "Any work affecting structural or fire safety" - so a garage door job that changes the opening size or framing does require a permit.

New Jersey sets residential wind criteria by rule and designates no windborne debris region. N.J.A.C. 5:23-3.21, the one- and two-family dwelling subcode, amends IRC Table R301.2, Climatic and Geographic Design Criteria: under the heading "Wind Design--Speed," insert "see Bulletin 19-1"; under "Wind Design--Topographic effects," insert "N/A" for Not Applicable; under "Wind Design--Special wind region," insert "N/A" for Not Applicable; and under "Wind Design--Windborne debris region," insert "N/A" for Not Applicable. The same rule provides that "Section R301.2.1.5, Topographic wind effects, shall be deleted, along with its subsections, tables and figures." Because the windborne debris region entry is Not Applicable statewide, the New Jersey dwelling subcode imposes no impact-rated opening protection on a garage door. Site-specific wind speed comes from DCA Bulletin 19-1, Design Loads for Ground Snow, Wind and Seismic (issued September 2019, revised September 2022; supersedes Bulletins 94-8, 03-4 and 05-2) at https://www.nj.gov/dca/codes/publications/pdf_bulletins/b_19_1.pdf, which directs users to the Applied Technology Council or ASCE 7 hazard tools and to apply the result "per the one- and two-family dwelling subcode, Section R301.2.1 and Figures R301.2(5)A and B."
