Not required

Required

Contractors must submit a completed Contractor Requirements packet (surety bond, business tax license as applicable, Tennessee state contractor's license, and proof of workers' compensation or exemption) to the Building Division before a permit is issued. Plans requiring review should expect a minimum of five business days before approval and permit issuance. Permit applications may be submitted through the CityView Permit Portal, by email to [email protected], or in person at 601 E. Main Street.

The City of Johnson City's "Inspections & General Information Guide" states inspections must be scheduled by the permit holder at least 24 hours in advance, by phone (423-434-6232, leave a message) or by email to [email protected], giving the permit number, project address, type of inspection, contact name/phone, and requested date; requests received by 4:30 p.m. may be scheduled as early as the next business day. For a project that does require a building permit (see roofing_permit_required and repair_permit_threshold -- typically new construction, or roof sheathing/deck replacement over 100 square feet on a single-family home), the residential building-inspection sequence runs Foundation/Footing, then Framing (which the guide notes occurs "AFTER the roof, all framing, fire blocking and bracing is in place"), then Foundation Drain/Damp-proofing, then Insulation, then the Final Building Inspection once all other trade finals (electrical, plumbing, HVAC) are approved. The guide names no separate roof-specific or mid-roof inspection distinct from framing and final. Ordinary single-family reroofing, which needs no permit at all in Johnson City, triggers no inspection requirement.

City of Johnson City adopts the 2018 International Residential Code, with Appendix Q (Tiny Homes), by reference under City Code Section 12-301(2). That section (read in full) amends the 2018 IRC in four respects only: Section R313 (automatic fire sprinkler systems) is made not mandatory; Chapters 34-43 (electrical installations) are deleted and replaced with the National Electrical Code (NFPA 70), 2017 edition; Section R314.6 (smoke alarm power source) gains an exception for certain existing-area alterations; and Chapter 11 (energy efficiency) is deleted and replaced by the separately adopted International Energy Conservation Code. None of these amendments touches Chapter 9 (roof-assembly coverings).

Required — City of Johnson City adopts the 2018 IRC by reference under City Code Section 12-301(2). That provision, read in full, amends only fire sprinklers, electrical installations, smoke alarm power source, and energy efficiency; it does not touch Chapter 9, so the base 2018 IRC's drip edge requirement at eaves and rakes applies unmodified. About drip edge

Not required — The City of Johnson City's own published Design Criteria sheet, distributed by the Building Division through its Contractor Requirements and Information document center for designers, lists "Ice Barrier Underlayment Required = No" alongside the city's other Table-R301.2(1)-type design values (ground snow load, seismic design category, wind speed, frost line depth, weathering, termite risk). No other provision in the city's adopted 2018 IRC amendments (Code of Ordinances section 12-301(2), read in full) addresses ice barrier underlayment. About ice & water barrier

Not required — The City of Johnson City's own "Inspections & General Information Guide" (Building Division, read in full, 4 pages) lists the residential building-inspection sequence as Foundation/Footing, Framing, Foundation Drain/Damp-proofing, Insulation and Final Building Inspection; it names no separate roof, dry-in or mid-roof inspection distinct from the framing and final inspections. Because ordinary single-family reroofing needs no city permit at all (see roofing_permit_required and repair_permit_threshold), no inspection of any kind applies to that scope of work either.

Not required — City of Johnson City adopts the 2018 IRC by reference under City Code Section 12-301(2). That provision, read in full, amends only fire sprinklers, electrical installations, smoke alarm power source, and energy efficiency; it does not touch Chapter 9 and adds no UL 2218 Class 4 impact-resistance mandate. No such requirement appears in the city's adopted code or its amendments.

The Building Division's published permit guidance ("When is a Permit Required" memo) states that no permit is required for residential re-roofs of single-family structures, or for residential roof sheathing replacements of 100 square feet or less. Roof sheathing replacements over 100 square feet appear on the same memo's permit-required list. City Code Section 12-103(1) states the general permit requirement the memo's exemptions operate against; the memo is the department's own published statement of which work it exempts.

Per the City of Johnson City's own published Design Criteria sheet (Building Division / Contractor Requirements document center, for designers): Wind Speed = 115 mph; Ground Snow Load = 15 psf; Seismic Design Category = B; Frost Line Depth = 12 inches; Winter Design Temperature = 14 degrees F; Weathering = Severe; Termite = Moderate-Heavy; Air Freezing Index = >0-1000. The document does not state an exposure category or specify whether the 115 mph figure is ultimate (Vult) or nominal (Vasd), though the 2018 IRC's Table R301.2(1) format that these values track uses ultimate design wind speed.

The City of Johnson City adopts the 2018 IRC by reference under City Code Section 12-301(2). That adopting/amending provision, read in full, amends only fire sprinklers, electrical installations, smoke alarm power source, and energy efficiency; it does not touch Chapter 9 (Roof Assemblies). The base 2018 IRC's roof recover/replacement layer provisions therefore apply unmodified.
