REFERENCE DESK · CODES & AUTHORITIES

Commercial Glass Reference Desk

No website determines the correct product or permit path for a specific opening; different authorities answer different parts of the question. No single reference — and no website — determines the correct product or permit path for a specific opening. Federal glazing rules, the adopted building code, Indiana design-release rules, local permits, historic-district review, and right-of-way review each answer a different part of the question. This page maps who governs what, defines the terms neutrally, and points to where each answer is confirmed.

AUTHORITY TABLE

Which authority governs which part

Each row lists what an authority or standard governs, what it does not decide, where to confirm it, and when it was last checked. Values come only from sources recorded in this site’s evidence ledger.

Authority or standard	What it governs	What it does not decide	Where to confirm	Last checked
16 CFR Part 1201 — Safety Standard for Architectural Glazing Materials	Federal safety standard for architectural glazing materials, including impact requirements, permanent certification marks, and fabrication limits for tempered glass.	Whether a specific Fort Wayne opening is a hazardous location under the adopted building code, or any local permit question.	eCFR (ecfr.gov) and the certifying entity's mark on the glass	July 25, 2026
Indiana Building Code as listed by Allen County (2012 IBC with Indiana amendments)	Adopted building-code requirements in Allen County, including safety-glazing hazardous-location provisions, subject to the code's listed exceptions and Indiana amendments.	Project-specific rulings. The provider and the authority having jurisdiction apply the rule to an actual opening.	Indiana DHS Fire & Building Safety and the Allen County Building Department	July 25, 2026
Indiana amendments to the adopted building code	State amendments that control where they differ from the model code.	Local permit classification or fees.	Indiana DHS Fire & Building Safety	July 25, 2026
ICC accessibility standard as listed by Allen County	Accessibility requirements referenced by the adopted code for entrances and openings.	Whether a specific entrance alteration triggers accessibility work — confirm with the issuing office.	Confirm with the Allen County Building Department	July 25, 2026
Indiana construction design release rules (675 IAC 12-6)	When state construction design release is required and which limited scopes — including replacement or reglazing of glass at 675 IAC 12-6-4(b)(5)(A) — are exempt.	The separate Allen County permit question; an exemption does not remove other applicable rules.	IDHS Plan Review	July 25, 2026

State design release, historic-district approval, or right-of-way use.	Allen County Building Department, Permits & Planning	July 25, 2026
Allen County contractor licensing / registration	Licensing or registration of contractors and subcontractors before projects begin; required permits are issued only to registered or licensed contractors.	Provider capability or availability for a specific request.	Allen County Building Department	July 25, 2026
Fort Wayne Historic Preservation	Certificate of Appropriateness review before most exterior work in a local historic district; Allen County's electronic routing for these properties took effect November 7, 2025.	Whether a property is in a district is confirmed by address — raise it on the first call.	Fort Wayne Historic Preservation	July 25, 2026
Fort Wayne right-of-way / barricade review	Review when work occupies or obstructs public space such as a sidewalk, parking lane, or street.	Building-permit or design-release questions.	City of Fort Wayne right-of-way office	July 25, 2026
Indiana trade-licensing guidance	Statewide occupational licensing guidance; Indiana does not issue a statewide glazier license.	Local registration requirements, which are handled by the local building department.	Confirm with the Allen County Building Department	July 25, 2026

Where a value is not verified, confirm it with the listed authority rather than assuming a number or interpretation.

DEFINITIONS

Definitions

Construction design release: A state-level review, administered by Indiana, that must be obtained before certain construction work; limited scopes — including replacement or reglazing of glass — are named as exempt at 675 IAC 12-6-4(b)(5)(A). An exemption from design release does not remove other applicable rules.
Local permit: An authorization issued by the local building department. In Allen County, the Allen County Building Department classifies work, applies its fee schedule, and issues permits. It is a separate question from the state design release.
Hazardous location: A position for glazing that the adopted building code identifies as needing safety glazing — for example, glazing near doors or certain large low panels — subject to the code's listed exceptions and Indiana amendments. This site does not determine whether a specific opening is a hazardous location; the provider and the authority having jurisdiction apply the rule to an actual opening.
Safety glazing: Glazing that meets the impact requirements of the applicable safety standard. Under the federal standard, certified safety glazing carries a permanent mark. Whether a given location requires safety glazing depends on the adopted code and its exceptions.
Permanent mark: A durable marking on certified safety glazing that identifies the certifying entity and the standard. Under 16 CFR Part 1201, safety glazing certified to the federal standard carries such a mark.
Certificate of Appropriateness: An approval from Fort Wayne Historic Preservation required before most exterior work begins in a local historic district and before a related building permit can be issued. Whether a property is in a district is confirmed by address.
Right-of-way permit: A City of Fort Wayne authorization required when work occupies or obstructs public space such as a sidewalk, parking lane, or street. It is separate from a building permit or a design release.
Insulated glass unit: A sealed assembly of two or more glass panes separated by a spacer, sometimes called an IGU. When the seal fails, the unit can fog; the unit is generally replaced rather than repaired in place.

METHODOLOGY AND LIMITATIONS

Methodology and limitations

Official-first sourcing. Each entry traces to a government or standards source — federal, state, county, or city — rather than to secondary summaries.
Retrieval dates. Every source is recorded with the date it was retrieved so a reader can see how current the underlying material is.
Normalization. Sources are described in a consistent structure — what they govern, what they do not decide, and where to confirm them — so different authorities can be compared side by side.
Review dates. Entries carry a last-checked date. The current material was reviewed July 25, 2026.
No project-specific ruling. This page does not decide any question about a specific opening, permit, or property. The provider and the authority having jurisdiction apply the rules to an actual project.
Rules change. Codes, amendments, fees, and processes are revised over time; confirm current requirements with the listed authority before relying on them.
Local determinations control. Where state amendments or local determinations differ from a model standard, the local determination controls.
Not professional advice. Nothing here is legal, engineering, code, or safety advice.

IN PREPARATION

Reference assets in preparation

Two source-normalized authority references are being prepared. They are not yet published and are not linked; each entry below is anchored so it can be referenced once the asset is live.

Architectural Glass Injury Statistics

IN PREPARATION

A source-normalized reference on injuries associated with architectural glazing, built from federal safety data, with methodology and retrieval dates.

How to Identify a Safety Glass Mark

IN PREPARATION

A practical reference for locating and reading the permanent safety-glazing mark on installed commercial glass, based on federal glazing rules.
