Adopted code

Township of Cinnaminson - Construction Office

No, Township of Cinnaminson, NJ does not require a permit for like-for-like roof replacement (Township of Cinnaminson - Construction Office). No permit is needed under state law to reroof a detached one- or two-family house; a townhouse, other attached dwelling or any other building in Cinnaminson needs one from the Township construction office, 1621 Riverton Road, Cinnaminson, 856-829-6000 extension 5 (the Building Inspections line on the office's page). The office's own permit guide lists "Roof: Building (Commercial only)," while the Township's Code Enforcement and Zoning FAQ says a new roof needs a permit "under most circumstances" and advises calling the Construction Department at extension 2312. Where a roof permit is required, section 265-7 of the Township Code (amended April 21, 2014 by Ord. No. 2014-8) says "The subcode fee for a permit to replace roofing or siding on a residence shall follow the schedule in Subsection A(1)(b) above," which charges "Up to $50,000: $30 per $1,000," then $23 per $1,000 for the next $50,000 and $19 per $1,000 above $100,000. The office says "Municipal Construction Permits WILL NOT be issued without proof of registration from any contractor working on your home" and lists "roofing and siding" among home improvements. The permit must be posted on the site with a copy of the approved plans, and the page warns that "State law mandates that the Construction Official issue a fine to any person who performs work without a permit if the construction is of a nature which requires a permit." Building inspections are made Tuesday and Thursday, 8:00 am to 12:00 pm and 5:00 pm to 7:00 pm. The construction permit application and subcode technical sections are posted on the Township's page as PDF forms.

Registration details
  • state_level: New Jersey requires home improvement contractors to register with the Division of Consumer Affairs. The Contractors' Registration Act as enacted in 2004 (P.L.2004, c.16), C.56:8-138(a), reads: "No person shall offer to perform, or engage, or attempt to engage in the business of making or selling home improvements unless registered with the Division of Consumer Affairs in accordance with the provisions of this act." The Uniform Construction Code's permit rule, N.J.A.C. 5:23-2.15(b)9, reads: "If work involves a home improvement performed by a contractor, such contractor shall be registered pursuant to N.J.S.A. 56:8-136 et seq. The registration number of the contractor shall appear on the permit application."
  • city_level: Chapter 225 of the Cinnaminson Township Code (adopted May 16, 2007 by Ord. No. 2007-13) says every contractor, naming "roofers" among others, "taking a contract for the erection, alteration, repair, renovation, moving or demolition of any commercial, industrial or business-oriented building or structure or portion thereof shall obtain and pay an annual license fee to the Township Construction Department Permit Office." Section 265-24 reads: "The annual fee for a contractors' license required under Chapter 225 of this Code shall be $250." Section 225-5 requires a certificate of insurance naming the Township, with "a minimum liability insurance of $300,000 bodily injury and $100,000 property damage." Section 225-2H exempts "All New Jersey contractors required to be licensed by the state according to the provisions of the Contractor's Registration Act, N.J.S.A. 56:8-136 et seq., where said contractors do not perform any work on commercial, industrial or business-oriented buildings in Cinnaminson Township." The construction office's page also says "Municipal Construction Permits WILL NOT be issued without proof of registration from any contractor working on your home."
Permit process note
No permit is needed under state law to reroof a detached one- or two-family house; a townhouse, other attached dwelling or any other building in Cinnaminson needs one from the Township construction office, 1621 Riverton Road, Cinnaminson, 856-829-6000 extension 5 (the Building Inspections line on the office's page).

The construction permit application and subcode technical sections are posted on the Township's page as PDF forms.
Adopted code
The 2024 International Residential Code, New Jersey edition, adopted by the State, with the Rehabilitation Subcode for work on existing buildings. New Jersey has one construction code, the Uniform Construction Code (N.J.A.C. 5:23), which every municipality enforces; municipalities do not adopt building codes of their own (N.J.S.A. 52:27D-123.1 and 52:27D-139). N.J.A.C. 5:23-3.21(a)1 adopts the International Code Council's "2024 International Residential Code known as the IRC/2024 as the one- and two-family dwelling subcode in New Jersey subject to the modifications stated at (c) below," and 3.21(b) applies it to "detached one- and two-family dwellings and townhouses not more than three stories above grade plane in height." The section was rewritten by R.2026 d.086, "effective August 17, 2026," in the Department of Community Affairs' print of the rules "adopted and published through the New Jersey Register, Vol. 58 No. 16," and the Department's Current Construction Codes page lists the "International Residential Code/2024, NJ ed" with an adoption date of Aug 17, 2026. Other buildings fall under the building subcode, the International Building Code/2024, NJ edition (N.J.A.C. 5:23-3.14). Roof work on an existing building is held to the Rehabilitation Subcode: "Existing structures, when repaired, renovated, altered or reconstructed, shall conform to the requirements of N.J.A.C. 5:23-6, Rehabilitation Subcode" (N.J.A.C. 5:23-2.4(a)). A six-month grace period follows the adoption. N.J.A.C. 5:23-1.6(a): "For a period of six months following the operative date of a subcode revision, applicants may submit a complete permit application, including all prior approvals, to be reviewed under the code in force immediately preceding the subcode revision." The rule history gives R.2026 d.086 no date other than its effective date, so on that reading the window runs from August 17, 2026 until about February 17, 2027: a complete application filed inside it may be reviewed under either the prior edition or the 2024 edition, at the applicant's choice, and one filed after it closes is reviewed under the 2024 edition. Everything above is New Jersey state law, the same in every municipality. Locally, Chapter 220 of the Township Code establishes the enforcing agency, the "Cinnaminson Township Code Enforcement Agency." The construction office's page says "This office follows the requirements under the DCA and Cinnaminson codes" and refers applicants to the Department of Community Affairs' list of current adopted codes; it names no code edition of its own.
Mid-roof inspection
Not required — No mid-roof inspection under state law. Reroofing a detached one- or two-family house is ordinary maintenance, and N.J.A.C. 5:23-2.7(c) says "No permit for, inspections of, or notice to the enforcing agency of ordinary maintenance shall be required." Where a reroof does need a permit, N.J.A.C. 5:23-2.18(b)1 says "Inspections of one- and two-family dwellings for which construction must cease until the inspection is made shall be limited to the following": footing trenches, foundations, utility services and a mid-point inspection, whose building item is "All structural framing, connections, wall and roof sheathing, and insulation." The list names no roof-covering or underlayment stage, and the rule does not say whether its sheathing item reaches a permitted reroof that replaces sheathing. Any further inspection a municipality requires "shall be of the type and nature that construction may continue without interruption" (5:23-2.18(b)3). Everything above is New Jersey state law, the same in every municipality. Locally, the Cinnaminson construction office's page lists inspection hours by subcode (building inspections Tuesday and Thursday, 8:00 am to 12:00 pm and 5:00 pm to 7:00 pm) and says "the applicant must call for final building, electrical, plumbing, and fire inspections prior to occupying"; it names no roof-covering stage.
Impact-resistant roofing
Not required — No impact-resistant roofing requirement under state law. The New Jersey Uniform Construction Code rules that reach a house reroof (the administrative rules in N.J.A.C. 5:23-1 and 5:23-2, the State's amendments to the 2024 International Residential Code at 5:23-3.21, and the Rehabilitation Subcode at 5:23-6) contain no UL 2218, Class 4 or hail-impact requirement for roof coverings. A municipality cannot add one: N.J.S.A. 52:27D-123.1 says "Any law or regulation to the contrary notwithstanding," the "alteration, renovation, rehabilitation, repair, maintenance, removal, or demolition of all buildings or structures already erected shall be regulated pursuant to the 'State Uniform Construction Code Act,'" and under 52:27D-139 local construction regulations were "deemed repealed and superseded" once the state code was promulgated. An owner may still choose an impact-rated roof covering. Everything above is New Jersey state law, the same in every municipality. The Cinnaminson construction office's page and Chapters 220 and 265 of the Township Code state nothing further on roof covering ratings.
Repair permit threshold
No permit and no size limit for reroofing a detached one- or two-family house; a permit for every other building. N.J.A.C. 5:23-2.7(c) lists items that "are ordinary maintenance and shall be treated as such by every enforcing agency" and says "No permit for, inspections of, or notice to the enforcing agency of ordinary maintenance shall be required." Item 1.x is "The repair or replacement of existing roof covering on detached one- and two-family dwellings," with no square-footage or percentage cap. N.J.A.C. 5:23-2.14(b)1 carries this into the permit rule: "Ordinary maintenance as defined in N.J.A.C. 5:23-2.7 shall not require a permit or notice to the enforcing agency." Two limits apply. First, the item covers only detached one- and two-family dwellings. Reroofing a townhouse or other attached dwelling, or any other building, falls under the general permit rule, N.J.A.C. 5:23-2.14(a): "It shall be unlawful to construct, enlarge, repair, renovate, alter, reconstruct or demolish a structure ... without first filing an application with the construction official." Some of that work may be "minor work" under N.J.A.C. 5:23-2.17A, which still needs a permit, but "work may proceed, upon notice to the enforcing agency, before the permit is issued" (5:23-2.14(b)2). The fee is municipal: "The municipality, in accordance with this chapter, shall establish by ordinance enforcing agency fees" (N.J.A.C. 5:23-2.25; fee standards at 5:23-4.18). Second, ordinary maintenance does not include "Any work affecting structural or fire safety" (5:23-2.7(b)4), so roof work that reaches rafters, trusses or other structure needs a permit even on a detached house. The rule does not say whether replacing roof sheathing alone is such work. Everything above is New Jersey state law, the same in every municipality. Locally, the Cinnaminson construction office's guide "When is a Permit Needed?" lists "Roof: Building (Commercial only)" and "Siding: Building (Commercial only)" and calls itself "a general guide"; its roof line does not mention townhouses or other attached dwellings. The Township's Code Enforcement and Zoning FAQ, on the same page, answers "Are permits required for a new roof, windows, siding, and other home improvements?" with "Yes, under most circumstances. There are some exceptions for very minor repairs. The best thing to do, is to call the Twp. Construction Dept. at 829-6000 ext 2312." The two Township statements do not agree with each other. Where a roof permit is required, section 265-7 of the Township Code says "The subcode fee for a permit to replace roofing or siding on a residence shall follow the schedule" for renovations, alterations and repairs: $30 per $1,000 of estimated cost up to $50,000, $23 per $1,000 for the next $50,000 and $19 per $1,000 above that.
Roof layer limit / recover
Two layers maximum, by state rule. Roof work on an existing building is held to the Rehabilitation Subcode (N.J.A.C. 5:23-2.4(a)), whose repair section, N.J.A.C. 5:23-6.4(e)7, reads: "Existing roof covering shall be removed before installing new roof covering when any of the following conditions occur: i. The existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing; ii. The existing roof covering is wood shake, slate, clay, cement or asbestos-cement tile; or iii. The existing roof has two or more applications of any type of roof covering." So one existing layer of asphalt shingles may be covered once; a roof that already has two layers, a wet or deteriorated roof, or a wood shake, slate, clay, cement or asbestos-cement tile roof must be torn off first. The answer is the same if a reroof is treated as renovation rather than repair: for work other than repair, N.J.A.C. 5:23-6.8(h)7 applies "All of Chapter 9 entitled 'Roof Assemblies', except Section R907" of the 2024 International Residential Code, and its reroofing section, R908.4, Exceptions, bars a recover "Where the existing roof has two or more applications of any type of roof covering." New Jersey's Chapter 9 amendments at N.J.A.C. 5:23-3.21(c)8 change only R903.4.1 and R905.1.2 and leave R908 as published. Everything above is New Jersey state law, the same in every municipality. The Cinnaminson construction office's page and Chapters 220 and 265 of the Township Code state nothing further on roof layers.
Sales & use tax
6.625% New Jersey Sales Tax; whether the roofing bill is taxed depends on the job. The Division of Taxation's guide Contractors and New Jersey Taxes (S&U-3, Rev. 5/25) refers to "New Jersey's 6.625% Sales Tax rate." A new roof is an exempt capital improvement: "New roof" is on the guide's list of "Exempt capital improvements," and "If the work results in an exempt capital improvement to real property, the contractor does not charge Sales Tax on the bill"; the owner gives the contractor a Certificate of Exempt Capital Improvement (Form ST-8). The roofer still pays tax on materials: "The contractor pays the Sales Tax on the cost of materials and supplies at the time of purchase." A repair is taxable. The guide lists "Fixing a leaky roof" among repairs and says "replacing a few loose bath tiles or a portion of a leaky roof is a repair to the existing real property. However, replacing all of the tiles or the entire roof with upgraded or improved materials would be an exempt capital improvement." On a taxable job the only deduction is a separately stated cost of materials, and "If the contractor does not itemize the materials and the labor for a taxable job, the entire receipt is subject to tax." Work for an exempt organization, a government agency or a qualified business in an Urban Enterprise Zone follows separate exemption rules. Everything above is New Jersey state law, the same in every municipality. The Cinnaminson construction office's page states nothing further on sales tax.

What building code does Township of Cinnaminson, NJ use?

The 2024 International Residential Code, New Jersey edition, adopted by the State, with the Rehabilitation Subcode for work on existing buildings. New Jersey has one construction code, the Uniform Construction Code (N.J.A.C. 5:23), which every municipality enforces; municipalities do not adopt building codes of their own (N.J.S.A. 52:27D-123.1 and 52:27D-139). N.J.A.C. 5:23-3.21(a)1 adopts the International Code Council's "2024 International Residential Code known as the IRC/2024 as the one- and two-family dwelling subcode in New Jersey subject to the modifications stated at (c) below," and 3.21(b) applies it to "detached one- and two-family dwellings and townhouses not more than three stories above grade plane in height." The section was rewritten by R.2026 d.086, "effective August 17, 2026," in the Department of Community Affairs' print of the rules "adopted and published through the New Jersey Register, Vol. 58 No. 16," and the Department's Current Construction Codes page lists the "International Residential Code/2024, NJ ed" with an adoption date of Aug 17, 2026. Other buildings fall under the building subcode, the International Building Code/2024, NJ edition (N.J.A.C. 5:23-3.14). Roof work on an existing building is held to the Rehabilitation Subcode: "Existing structures, when repaired, renovated, altered or reconstructed, shall conform to the requirements of N.J.A.C. 5:23-6, Rehabilitation Subcode" (N.J.A.C. 5:23-2.4(a)). A six-month grace period follows the adoption. N.J.A.C. 5:23-1.6(a): "For a period of six months following the operative date of a subcode revision, applicants may submit a complete permit application, including all prior approvals, to be reviewed under the code in force immediately preceding the subcode revision." The rule history gives R.2026 d.086 no date other than its effective date, so on that reading the window runs from August 17, 2026 until about February 17, 2027: a complete application filed inside it may be reviewed under either the prior edition or the 2024 edition, at the applicant's choice, and one filed after it closes is reviewed under the 2024 edition. Everything above is New Jersey state law, the same in every municipality. Locally, Chapter 220 of the Township Code establishes the enforcing agency, the "Cinnaminson Township Code Enforcement Agency." The construction office's page says "This office follows the requirements under the DCA and Cinnaminson codes" and refers applicants to the Department of Community Affairs' list of current adopted codes; it names no code edition of its own.

Is a mid-roof inspection required in Township of Cinnaminson, NJ?

No. No mid-roof inspection under state law. Reroofing a detached one- or two-family house is ordinary maintenance, and N.J.A.C. 5:23-2.7(c) says "No permit for, inspections of, or notice to the enforcing agency of ordinary maintenance shall be required." Where a reroof does need a permit, N.J.A.C. 5:23-2.18(b)1 says "Inspections of one- and two-family dwellings for which construction must cease until the inspection is made shall be limited to the following": footing trenches, foundations, utility services and a mid-point inspection, whose building item is "All structural framing, connections, wall and roof sheathing, and insulation." The list names no roof-covering or underlayment stage, and the rule does not say whether its sheathing item reaches a permitted reroof that replaces sheathing. Any further inspection a municipality requires "shall be of the type and nature that construction may continue without interruption" (5:23-2.18(b)3). Everything above is New Jersey state law, the same in every municipality. Locally, the Cinnaminson construction office's page lists inspection hours by subcode (building inspections Tuesday and Thursday, 8:00 am to 12:00 pm and 5:00 pm to 7:00 pm) and says "the applicant must call for final building, electrical, plumbing, and fire inspections prior to occupying"; it names no roof-covering stage.
