Which authority and version apply to this proposal, and what must be approved and recorded before the next stage?
Identify the exact location, proposed use, complete work and application history. Obtain the responsible authority’s adoption and amendment route, then use the corresponding technical publications. Coordinate required inspections and retain actual results and final records.

What this guide helps you do
For building an approval and inspection question file. Unincorporated Boulder County is a local example; municipal, state and specialized programs can differ. This guide is not a legal opinion, complete code analysis, permit exemption, inspection approval or authority to occupy.
Identify location, use and responsible authority
Record the address/parcel, whether it is inside a municipality, the existing approved use and the proposed change. Describe all connected work, including utilities and intended occupancy, rather than a convenient label such as shed, repair or tiny home. Locate actual planning, building and relevant trade/service authorities. Preserve existing permit numbers and dates. If several agencies are involved, ask who reviews each part and what evidence one needs from another before work can proceed.
Match the application date to adopted documents
Boulder County’s current page assigns its July 1, 2026 update to building permit applications submitted on or after that date in unincorporated territory, using 2021 I-Codes with local amendments. It separately lists earlier versions by application period and explains that cities adopt independently. Use the actual history and official direction for a particular project. The neighboring planning FAQ’s old 2015 reference remains flagged; copying a model-code edition from a general search result cannot settle applicability. Source: Boulder County adopted-code and amendment history.
Ask about the complete scope before assuming an exemption
B05 explains that a building-permit exemption does not authorize violations of other laws or requirements. Ask the actual authority about the work, use, land-use approvals and services together. Its older linked amendment file is not the current version for every new application; return to the adopted-code history. Record the official response with its date, scope and any conditions. A contractor’s informal assurance or the fact that a similar structure exists nearby is not the project’s approval record. Source: Boulder County permit requirements B05.
Read the identified technical publication
After identifying the adopted edition and amendments, use ICC’s original library to locate the corresponding model text and referenced standards. Keep the title, edition, relevant section and local changes together. Its gateway separates model publications, local collections and standards, but availability does not prove current local adoption. Some content and tools have subscription or credit terms; no purchase is needed to follow this guide. A calculator or generated answer should not replace the actual applicable text and responsible official’s interpretation. Source: ICC Digital Codes library gateway.
Schedule verification before dependent work
Ask which inspection stages apply, when work must remain visible, who requests them and how to obtain the result. Boulder County’s route uses permit and inspection identifiers and does not guarantee next-day service. Some photo reviews are specified; others require the inspector’s discretion. Do not assume every stage can be documented by a homeowner’s photograph. Roof access and exposed electrical equipment belong with qualified workers. Keep corrections, repeat-inspection requirements and the actual accepted result before proceeding. Source: Boulder County inspection coordination.
Keep completion distinct from separate permissions
Collect approved plans, amendments, conditions, inspection results, corrections and the actual final documentation required for the proposal. Ask whether separate utility release, fire, land-use or occupancy steps remain. Keep open items visible; an application submission, inspection request, paid fee or single passed stage is not proof that all work and uses are approved. A future owner should be able to trace what was approved, when, by whom and under which documents.
A pathway to practice
- Define place and proposal: Jurisdiction, use, scope, history
- Identify adopted requirements: Edition, date, amendments, authority
- Coordinate stages and results: Review, inspection, correction, record
- Close and preserve the file: Final conditions and separate permissions

From the Whole Earth registry to current practice
Spring 1969 Audel Guides (PDF page 26, printed page 24; WE69S-E050/WE69S-L039) acknowledges the reviewers’ limited ability to compare specialized manuals and asks for informed criticism. That visually verified editorial caution informs this guide’s separation of a reference from applicable authority. The link to modern code/version and inspection work is editorial; old manual diagrams are not adopted.
