Project 02

Determine Whether a Residential Project Requires a Permit

Evaluate one defined residential project and produce a documented permit decision identifying required approvals, possible exemptions, licensed-trade boundaries, and official questions, using only the verified sources in the Project 01 reference binder.

Field Cue System

These cues appear at the point of work. They identify safety, code, professional-boundary, and documentation issues before they become an unverified assumption or an unauthorized start of regulated work.

△

Safety Cue

Task-specific guidance for site walks, photo documentation, and handling existing conditions.

✋

Critical Safety Cue

A stop-work condition: the learner must not begin regulated work or rely on an unverified exemption.

⛑

Field Safety Cue

Practical handling of official contacts and written clarification requests.

▤

Code Alert

Permit triggers, classifications, and exemptions vary by jurisdiction. Verify directly rather than from memory.

▧

Professional Boundary Cue

Identifies determinations reserved for the building official, plans examiner, licensed trade, or design professional.

▱

Documentation Cue

Recording, sourcing, and dating guidance for every entry placed in the permit matrix and decision file.

Job Overview

This project qualifies you to evaluate a defined residential project scope and produce a documented, source-supported permit decision before any work begins. The finished work product is one permit decision file containing a classified scope, a permit matrix, identified exemptions and their limitations, licensing and professional-boundary findings, official clarification correspondence, and a final documented decision of permit required, permit not required based on a cited exemption, or unresolved pending official determination.

You will define the property and proposed scope, classify each scope item using the jurisdiction's own definitions, identify structural, plumbing, electrical, mechanical, site, and zoning triggers, identify licensing and professional requirements, locate and test any claimed exemption, prepare focused official questions, contact the permit authority, and issue a documented decision supported entirely by the Project 01 binder and direct agency confirmation.

This is the second project in the book. It depends entirely on the authority register, adopted-code sources, and exemption resources built in Project 01. The permit decision produced here becomes the controlling input for Project 03's application packet and for every later inspection-readiness project that assumes the correct permits are already in place.

Skills You Will Demonstrate

  • CP-007 — Identify permit triggers across structural, MEP, site, and zoning scope items.
  • CP-008 — Distinguish repair from alteration, addition, demolition, relocation, and change of use using local definitions.
  • CP-009 — Identify structural work requiring a permit or design-professional review.
  • CP-010 — Identify plumbing, electrical, HVAC, and other MEP work requiring a permit or licensed trade.
  • CP-011 — Identify exterior, site, and zoning triggers, including explicit permit exemptions and their limitations.
  • CP-012 — Prepare a documented permit-decision checklist supported by official sources and correspondence.

Where This Skill Fits

Every regulated residential project starts with the same question this chapter answers: does this specific scope require a permit, and under which classification? Project 03 cannot assemble an application packet until this decision identifies which permits apply and which licensed trades or design professionals are required. Every later inspection-readiness project in this book assumes the underlying permit was correctly identified and issued before work began.

The classification discipline in this chapter — using the jurisdiction's own definitions rather than assumption, and treating an exemption as narrow and conditional rather than automatic — is the same discipline the Chapter 19 remodel review and the Chapter 20 capstone depend on.

Scope and Intended Use

This project covers:

  • defining the property, scope, and existing conditions for one proposed residential project
  • classifying each scope item as maintenance, repair, alteration, addition, demolition, relocation, or change of use using local definitions
  • identifying structural, plumbing, electrical, mechanical, site, and zoning permit triggers
  • identifying licensing, owner-builder, and design-professional requirements
  • locating and testing any claimed permit exemption against its official conditions and limitations
  • preparing and submitting official clarification questions for ambiguous scope
  • issuing and filing a documented permit decision

This project does not authorize the learner to:

  • begin demolition, excavation, structural work, utility disconnection, or equipment replacement before the permit decision and any required permit are complete
  • treat a claimed exemption as confirmed without verifying its exact conditions and limitations at the official source
  • size, approve, or field-modify any structural, MEP, or energy component
  • represent this decision checklist as a permit approval, inspection result, or legal opinion

Any scope item that cannot be classified from an official source must be logged as unresolved and referred to the responsible authority rather than decided by assumption.

Reference Conventions

Establish these references before any scope item is classified, and apply them consistently across the permit matrix.

TermDefinition
Permit triggerA scope condition — such as structural, MEP, site, or zoning work — that the jurisdiction's rules require a permit to address
ClassificationThe jurisdiction's own category for the scope item: maintenance, repair, alteration, addition, demolition, relocation, or change of use
Permit exemptionA specific, conditional carve-out from permit requirements, confirmed at the official source, that does not remove code, zoning, licensing, safety, utility, or HOA obligations
Stop-work itemAny activity that cannot begin before permit issuance or a required separate approval
Unresolved itemA scope condition that cannot yet be classified from an available official source and must be tracked until the authority responds
Permit matrixThe document linking each scope item to its authority, permit type, exemption basis if any, license requirement, document need, and decision status

Property and Scope Record

Before classifying any scope item, record the property, scope, and decision context directly on the permit matrix:

Property address: ______     Owner: ______     Existing permit history: ______

Proposed work description: ____________     Location and dimensions: ____________     Systems affected: ____________

Estimated cost or valuation (if required by the jurisdiction): ______     Intended use: ____________

Prerequisites

Common Field Fundamentals

Every permit decision in this book, from a simple repair to the Chapter 20 capstone's full scope classification, follows the same sequence: define the scope, classify each item against the jurisdiction's own definitions, identify every trigger and exemption, identify licensing and professional boundaries, resolve ambiguity through the authority rather than assumption, and issue a documented decision. Learning that sequence here, on one defined project, means every later chapter's permit work starts from a method you already trust.

Scope DefinitionProperty, owner, proposed work, dimensions, systems, valuation
ClassificationMaintenance, repair, alteration, addition, demolition, relocation, change of use
Trigger IdentificationStructural, MEP, site, zoning, fire, health, and utility triggers
Exemption TestingSource, conditions, and limitations of any claimed exemption
Licensing ReviewContractor, trade, owner-builder, and design-professional requirements
ClarificationFocused official questions and recorded agency responses
Permit MatrixScope item, authority, permit type, exemption, license, status
DecisionPermit required, exempt with citation, or unresolved pending determination

Classification, Exemptions, and Stop-Work Boundaries

Every scope item receives one classification using the jurisdiction's own definitions, and every claimed exemption is tested against its exact published conditions before it is relied upon. Record the source, section, and date verified for every classification and exemption entered in the permit matrix.

C. Resource Takeoff

  • Scope data: one defined residential project with property, owner, proposed work, dimensions, systems affected, and intended use recorded before classification begins.
  • Reference resources: the completed Project 01 binder's authority register, adopted codes, licensing section, and exemption sources.
  • Documentation: photographs, sketches, plans, equipment information, and existing permit history for the property.
  • Verification allowance: at least one completed contact with the permit authority for a scope item that could not be classified from published sources alone, with the response recorded in the clarification log.

Decision documentationThe final decision is documented, dated, reviewed with the applicable parties, and filed with its supporting sources

E. Preparation — Define and Document the Scope

  1. Define the property, owner, proposed work, location, dimensions, systems affected, cost or valuation if required, and intended use. Record this information on the Property and Scope Record above before classifying any item.
  2. Collect photographs, sketches, plans, equipment information, and existing permit history relevant to the scope. File these with the scope description in the decision file.
  3. Identify the authority having jurisdiction and confirm the current permit rules from the Chapter 1 binder. Do not rely on a rule that has not been verified in the Project 01 binder or confirmed directly with the authority.

F. Classify the Scope

  1. Classify each scope item using local definitions for maintenance, repair, alteration, addition, demolition, relocation, change of use, and new construction. Record the classification and its official source for each item in the classification record.
  2. Do not treat replacement in kind as exempt until the local definition and limitations are verified. Confirm the exact conditions of any "like-for-like" or "replacement in kind" language at the official source.
  3. Identify structural work affecting foundations, bearing walls, beams, headers, posts, joists, rafters, trusses, shear walls, bracing, stairs, guards, decks, or retaining walls. Record each affected structural component in the trigger register.
  4. Identify work affecting exterior openings, roof structure, siding, fire separation, egress, occupancy, accessibility, or weather protection. Record each affected item in the trigger register.

G. Identify MEP, Site, and Zoning Triggers

  1. Identify plumbing work involving fixtures, water, drainage, venting, gas, water heaters, backflow, sewer, septic, well, or irrigation. Record each affected plumbing item in the trigger register.
  2. Identify electrical work involving service, panels, feeders, circuits, receptacles, lighting, alarms, generators, EV charging, solar, low voltage, or utility connections. Record each affected electrical item in the trigger register.
  3. Identify HVAC and mechanical work involving equipment, ducts, ventilation, exhaust, refrigerant, fuel, combustion air, chimneys, flues, or condensate. Record each affected mechanical item in the trigger register.
  4. Identify site work involving excavation, grading, drainage, driveways, right-of-way, utilities, trees, floodplain, erosion control, wells, septic, pools, fences, or accessory structures. Record each affected site item in the trigger register.
  5. Identify zoning or planning triggers for setbacks, use, height, lot coverage, parking, historic review, design review, or accessory dwelling units. Record each affected zoning item in the trigger register.
  6. Identify fire-department, health-department, utility, public-works, environmental, or other separate approvals. Record each separate agency approval required by the scope.

H. Identify Professionals, Licensing, and Exemptions

  1. Identify project conditions requiring architect, engineer, surveyor, geotechnical, energy, testing, or special-inspection services. Record each condition in the licensing findings.
  2. Identify contractor and trade licensing requirements for the proposed work. Record the applicable license categories from the Project 01 licensing section.
  3. Identify owner-builder options and required disclosures without assuming the owner qualifies. Record the disclosure requirement and route qualification questions to the owner and authority, not to assumption.
  4. Locate explicit permit exemptions and record their source, conditions, and limitations. File each exemption citation with its exact published wording.
  5. Confirm that an exemption does not remove code, zoning, licensing, safety, utility, or HOA obligations. Record this confirmation next to each exemption citation.
  6. Separate exempt work from permit-required work when the project contains both. Mark each scope item in the permit matrix as exempt, permit-required, or unresolved individually rather than applying one status to the whole project.
  7. Identify whether work may proceed under an over-the-counter, express, standard, deferred, or phased permit process. Record the applicable process for each permit-required item.
  8. Identify whether demolition or investigative opening requires authorization before the main permit. Add any required pre-authorization to the stop-work list.

I. Resolve Ambiguity and Issue the Decision

  1. Prepare specific official questions for ambiguous scope rather than describing the project vaguely. Draft one focused question per unresolved item, tied to the exact scope condition.
  2. Contact the permit authority through the approved channel and record written guidance where available. Use the Field Safety Cue above when making contact.
  3. Record the official contact, date, question, response, and any stated limitations. Complete one clarification-log entry per contact.
  4. Prepare a permit matrix listing each scope item, authority, permit type, exemption basis if any, license requirement, document need, and decision status. Complete one row per scope item.
  5. Prepare a stop-work list for activities that cannot begin before permit issuance or separate approval. Cross-check every stop-work item against the permit matrix.
  6. Identify permit, design, fee, review, inspection, and schedule impacts for the Book 24 estimate or project budget. Record these impacts for use in cost and schedule planning.
  7. Review the decision with the owner, contractor, and design professional as applicable. Record the reviewers and the date of review.
  8. Issue a documented decision of permit required, permit not required based on cited exemption, or unresolved pending official determination. Record the decision, its date, and its supporting sources in the final decision record.
  9. File the decision checklist, sources, correspondence, and project-scope description in the compliance record. Store the completed decision file where it is available for Project 03.

Skill Check

  1. Why must every scope item be classified using the jurisdiction's own definitions rather than a general industry understanding of "repair" or "alteration"?
  2. What conditions must be confirmed before relying on a "replacement in kind" exemption?
  3. What information must the trigger register capture for a scope item affecting a bearing wall?
  4. Why does a permit exemption never remove code, zoning, licensing, safety, utility, or HOA obligations?
  5. What must the learner do before assuming an owner qualifies as an owner-builder?
  6. What belongs on the stop-work list, and why must it be cross-checked against the permit matrix?
  7. Why must an unresolved scope item be referred to the permit authority rather than decided by the learner's best judgment?
  8. What are three possible causes of an incomplete trigger register, and how does the learner confirm which one occurred?
  9. What must the final decision record include before the decision file is considered complete?
  10. Why does this chapter require the learner to contact the permit authority for at least one unresolved item rather than leaving it undetermined?

Performance Check

With the scope classified and the permit matrix complete, review the finished decision file against the Acceptance Standards table and confirm every scope item has a sourced classification, every trigger present in the scope is recorded, every claimed exemption is tested against its official conditions, licensing and professional-boundary findings are complete, the stop-work list is cross-checked against the matrix, at least one unresolved item has a recorded agency response, and the final decision is documented, dated, and reviewed. Complete the Permit Decision Worksheet and correct any failed item before beginning Project 03. If an entry fails, identify whether the error occurred in classification, trigger identification, exemption testing, licensing review, or decision documentation before correcting and re-running the affected check.

Project Closeout

You have completed the second project in the building codes, permits, and inspections sequence: determining whether a residential project requires a permit. This project required you to identify permit triggers across structural, MEP, site, and zoning scope items (CP-007), distinguish repair from alteration, addition, demolition, relocation, and change of use using local definitions (CP-008), identify structural work requiring a permit or design-professional review (CP-009), identify plumbing, electrical, HVAC, and other MEP work requiring a permit or licensed trade (CP-010), identify exterior, site, and zoning triggers, including explicit permit exemptions and their limitations (CP-011), and prepare a documented permit-decision checklist supported by official sources and correspondence (CP-012).

You now have a filed, source-supported permit decision and a repeatable classification method you can apply to any future residential project scope. That decision carries directly into the next project: assembling the basic residential permit application packet for every scope item classified as permit-required.

Store the filed decision where it remains available to Project 03 and every later project in this book. You will recheck and reuse this exact classification method throughout the rest of this book.
