WHERE. The Building Commissioner's office is at 111 N Center St, Plymouth, IN 46563, on (574) 936-2824, fax (574) 936-5256, with Dennis Manuwal Jr. as Building Commissioner. The Commissioner is also the City's Zoning Administrator and Floodplain Manager, so the building permit and the Improvement Location Permit come from the same office. Applications and contractor registration are online through the City's GovWell portal. BEFORE APPLYING. The City's checklist says its items "must be completed, submitted, and approved prior to applying for any permit": a site plan with dimensions to lot lines, an assigned address, the list of contractors and subcontractors, and their City registration, among others. FEES. Under the codified schedule from Ord. 2024-2238 a residential roof permit is $75 and a commercial one $100. Ord. 2026-2261, passed and signed June 8, 2026 with its own stated effective date of October 1, 2026, replaces both with .05 percent of project valuation, with minimums of $75 residential and $100 commercial. INSPECTIONS. Section 153.10 has the Commissioner designate, permit by permit, the stage at which each inspection must be requested, with 24 hours' notice. The only stages the ordinance itself fixes are foundations before concrete and electrical, mechanical, plumbing or insulation work before it is covered. No roofing stage is fixed, so ask when the permit issues whether the deck must be seen. A re-inspection caused by non-compliance costs $30, and so does a late inspection request.

THE CITY ADOPTS NO EDITION OF ITS OWN; ITS ADOPTION FLOATS WITH THE STATE RULE. Section 153.06(A) of the Building Code, from Ord. 2008-1973, passed November 10, 2008, incorporates the state commission's rules by reference and says they "shall include later amendments to those articles as the same are published in the Indiana Register or the Indiana Administrative Code with effective dates as fixed therein". Its list includes "Article 14 - One and Two Family Dwelling Code. Indiana Residential Code (675 I.A.C. 14-4)". Chapter 153 was read in full, all twenty sections plus the penalty section. Its two 2026 amendments, Ord. 2026-2257 (February 23, 2026, permit application attachments) and Ord. 2026-2259 (May 26, 2026, emergency key boxes on commercial, industrial and multifamily work), leave section 153.06 alone. WHAT ARTICLE 14 REACHES. The state residential rule is 675 IAC 14-4.4, the 2020 Indiana Residential Code. The State Building Commissioner's memo states: "The 2020 Indiana Residential Code adopts, and amends, the first printing of the 2018 International Residential Code." The City writes no roofing amendment to it anywhere in Chapter 153.

Required — REQUIRED BY THE STATE CODE, NOT BY A PLYMOUTH ORDINANCE. The Indiana State Building Commissioner's memo on ice/water shield and drip edge reproduces R905.2.8.5 as adopted in the 2020 Indiana Residential Code: "A drip edge shall be provided at eaves and rake edges of shingle roofs." The memo goes on to give the overlap, extension and fastening rules. 675 IAC 14-4.4 amends R905.2.8 only by deleting the word "approved" and does not touch R905.2.8.5. Chapter 153 of the Plymouth Code has no drip-edge provision, and IC 22-13-2-3(c) leaves the City no power to add or remove one. About drip edge

Required — REQUIRED IN MARSHALL COUNTY BY THE STATE TABLE. The Indiana Residential Code's Table R301.2(1), as substituted by 675 IAC 14-4.4-5, runs county by county, and the Marshall row marks ice shield underlayment required Yes. R905.1.2 then requires an ice barrier for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes in areas so designated. The State Building Commissioner's memo spells out the consequence: "there are specific counties in which it is always required (per Table R301.2(1))". Marshall is one of them. The code's own exception is for detached accessory structures not containing conditioned floor area. Plymouth has no ordinance touching this; Chapter 153 contains no ice or snow provision. About ice & water barrier

Not required — NOT REQUIRED. Neither Chapter 153 of the Plymouth Code, read in full, nor the City's Zoning Ordinance contains a UL 2218 or Class 4 impact requirement for roof coverings. The state rule the City adopts, 675 IAC 14-4.4, makes no impact-resistance amendment to the roof assemblies chapter, and IC 22-13-2-3(c) would bar the City from enacting one. Impact-resistant shingles are an insurance and warranty decision in Plymouth, not a code requirement.

NO THRESHOLD, AND ROOFING IS NAMED IN TWO SEPARATE INSTRUMENTS. The Building Code at section 153.08 reads: "A permit shall be obtained before beginning construction, alteration or repair of any building or structure, including a fence." It sets no dollar or square-footage floor. The fee schedule at section 151.02 carries its own residential line for a roof. SEPARATELY, THE ZONING ORDINANCE ASKS FOR AN IMPROVEMENT LOCATION PERMIT. Article 11, Section 060 B states that "City of Plymouth requires that an Improvement Location Permit be obtained for the following:" and item 13 of that list is "Roof or re-roofing". The City's published Zoning Ordinance records this in its table of amendments as PC 2026-07, dated June 2, 2026, an Article 11 amendment on permitting requirements for accessory structures and roofs. The only exemption in Section 060 C covers "cosmetic (non-structural) changes to any structure", with replacement windows in existing openings, siding and repainting as its examples. Roofing is not among them, and it is listed by name as work that needs the permit. The Building Commissioner's own page agrees: "The following is a list of work/items requiring a permit." Roof is on that list.

THE FIGURES ARE THE STATE'S COUNTY-INDEXED TABLE, NOT A PLYMOUTH ENACTMENT. Table R301.2(1) of the Indiana Residential Code, as substituted by 675 IAC 14-4.4-5, gives the Marshall County row as wind speed 115 mph, seismic design category A, ground snow load 30 psf, frost depth 36 inches, winter design temperature 1 degree Fahrenheit, decay slight to moderate, termite moderate to heavy, weathering severe, ice shield underlayment required Yes, air freezing index 2000 and mean annual temperature 50.0 degrees. The City publishes no design criteria of its own; Chapter 153 contains no wind, snow or seismic provision, and IC 22-13-2-3(c) bars it from varying these locally.

NO CITY RULE AND NO STATE AMENDMENT, SO THE BASE CODE APPLIES. Chapter 153 of the Plymouth Code was read in full and writes no technical roofing provision at all; its adoption at section 153.06 attaches no amendment. The state rule, 675 IAC 14-4.4, amends the roof assemblies chapter in only four places: it deletes the last sentence of the rooftop photovoltaic section R902.4, the word "approved" from R905.2.6 and from R905.2.8, and the word "printed" from R905.2.8.4. It does not touch the reroofing section. Nor could the City add a rule of its own: IC 22-13-2-3(c) bars a city from an ordinance "that conflicts with or includes more stringent or detailed requirements than the commission's rules". So the 2018 International Residential Code applies unchanged. Section R908.3.1.1 bars a recover "Where the existing roof has two or more applications of any type of roof covering." One existing layer may be recovered; a second forces a full tear-off. Establish the layer count before quoting a recover.

NO LOCAL SHEATHING RULE. Chapter 153 was read in full and contains no sheathing or decking provision; it deals with the commissioner's office, adoption by reference, permits, inspections, entry, stop orders, certificates of occupancy, appeals and penalties. IC 22-13-2-3(c) bars the City from adding a rule more stringent or detailed than the state's. The deck side of an asphalt reroof is therefore answered by the 2018 International Residential Code as incorporated by 675 IAC 14-4.4, whose roof-chapter amendments are the four word and sentence deletions described in this record's layer field. None of them reaches the sheathing provisions.

7.00% in Plymouth, the Indiana state sales and use tax rate, with no county or municipal add-on. The Department of Revenue describes the obligation as registering "to collect a seven percent sales tax". Indiana authorises no local-option general sales tax, so neither Marshall County nor the City levies anything on top of the state rate.
