This section defines the authority of the code official—how they enforce, interpret, accept alternates, require reports/tests, and keep records.🧠 Plain English Breakdown•Enforcement & interpretations (Sections 104.1–104.2): The code official enforces the IMC and can issue interpretations/policies—but cannot waive code requirements.•Listed compliance (Section 104.2.1): “Listed” means a product is evaluated by a listing agency (UL/ETL/ICC-ES) to a specific published standard and edition, gets a mark/report, and must be installed exactly per that report and the manufacturer’s installation instructions. Be ready to show the listing/evaluation report ID and the relevant Installation & Operations Manual (IOM) pages.•Technical assistance & tests (Sections 104.2.2, 104.2.2.4): The official can require engineer-sealed opinions/reports and testing by acceptable labs to prove compliance (costs are not on the jurisdiction).•Alternatives—materials/designs/methods (Sections 104.2.3–104.2.3.7): Alternatives may be approved if they meet code intent and are equivalent in quality, strength, effectiveness, durability, safety, and fire safety; expect a written application/decision, and possibly evaluation reports, testing, or peer review.•Modifications (Sections 104.2.4, 104.2.4.1): Case-by-case modifications may be granted for practical difficulties without reducing life/fire/structural/accessibility safety; relief is very limited in flood hazard areas.•Permits, inspections, records (Sections 104.3, 104.7): The office processes permits/inspections/notices and keeps official records for at least 5 years.•Right of entry & warrants (Sections 104.4, 104.4.1, 104.5): Inspectors have legal authority to enter at reasonable times to enforce the code. They present ID and request entry; if refused, they can obtain a warrant, after which entry cannot be denied.•Approvals & reuse (Sections 104.9–104.9.1): Install as approved; reuse only if in good working order and approved.🏗️ Why It Matters in Design & Construction This is the playbook for approvals: what documentation reviewers expect (listing proof + IOM), how to lawfully use alternates/mods, and that inspectors have lawful access to verify safety and compliance.🔧 Field Tip Before you submit your permit set or equipment submittals, send a one-page pre-submittal to the code official with:1. the IMC sections you’re relying on (e.g., 104.2.1 listing, 104.2.3 alternative, 104.9.1 reuse),2. the listing proof (agency mark, published standard & edition, report ID) and the IOM pages,3. a request for a 10-minute alignment call. It’s quick—and it cuts redlines.Daily Code Talk #5 – IMC Section 105: PermitsThis section covers when a permit is needed, how to apply, time limits, approvals, expirations, and special cases (emergencies, annual permits).🧠 Plain English Breakdown•Where required (105.1): Permit before you erect, install, enlarge, alter, repair, remove, convert, or replace a mechanical system. Emergency? Fix now, apply next business day.•Annual permits (105.1.1–105.1.2): For facilities with in-house trades; keep detailed records available to the code official.•No permit needed (105.2): Certain portable equipment, minor parts, internal piping within listed equipment, and self-contained refrigeration ≤10 lb or ≤1 hp. Exemption ≠ permission to violate code.Apply (105.3–105.3.2): Use AHJ form with fees, scope, location, occupancy; pre-issuance inspection allowed. Applications abandon after 180 days unless pursued; extensions in writing.•Issuance & docs (105.4–105.4.2): Permit issued when compliant and fees paid; stamped drawings govern. Partial permits allowed—at applicant’s risk. Approval never authorizes a violation; AHJ can require corrections.•Expiration & extensions (105.4.3–105.4.4): Permit expires if not started within 180 days or suspended 180 days. One 180-day extension with cause; fee typically ½ a new permit.•Suspend/revoke, prior approvals, posting (105.4.5–105.4.7): AHJ may suspend/revoke permits issued in error/bad info; lawful prior permits generally stand; post permit on site to completion.🏗️ Why It Matters in Design & Construction Permits control liability and schedule: building without or beyond one risks stop-work, fines, demo, and insurance issues. Track both 180-day clocks (application and permit) to avoid re-permitting delays. Use annual permits to streamline in-kind maintenance only with a clean work ledger. Partial permits phase work but don’t guarantee full approval. Emergency replacements are allowed—but file the permit next business day and document scope (photos, nameplate data).🔧 Field Tip Before issuing drawings, call the AHJ to confirm permit type (standard/annual/emergency) and whether partial permits are allowed; include a one-page phasing plan if splitting scopes. When you file, set Day-170 reminders for both the application and the permit; if slipping, request a written 180-day extension with cause. Build only from the approved, stamped set—submit revisions for field changes. Keep on site: the posted permit, stamped sheets, and key listing/installation pages; for annual permits, maintain a simple work ledger.
