What this governance record addresses
A source register should not be a timeless list of links. This page publishes each source's role, geography, lifecycle, review interval, due date and automated result; row dates distinguish the 25 July 2026 baseline from targeted rechecks on 30 July and 2026-10-17.
Important boundary: Even HTTP 200 can redirect away from the intended record; HTTP 202, 403 or 429 does not automatically make a source broken. Automated retrieval does not validate content, edition, amendment or withdrawal status, or local adoption.
Source-by-source maintenance table
| Source | Evidence role | Geography | Lifecycle | Retrieval check | Next review | Observed status |
|---|---|---|---|---|---|---|
| icc-irc International Code Council | Technical or regulatory context | United States | Edition or archival record 365 days | Manual follow-up required (HTTP 403; access_restricted_403) The registered URL rejected the automated client and requires browser follow-up. | ||
| icc-ibc International Code Council | Technical or regulatory context | United States | Edition or archival record 365 days | Manual follow-up required (HTTP 403; access_restricted_403) The registered URL rejected the automated client and requires browser follow-up. | ||
| aluminum-manual The Aluminum Association | Technical or regulatory context | United States | Edition or archival record 365 days | Automated retrieval succeeded (HTTP 200) The registered Aluminum Association Aluminum Design Manual 2020 page returned HTTP 200 on 2026-10-11 and was folded into the deflection-and-serviceability check group. It is the structural aluminium design reference cited by the International Building Code and records aluminium's elastic modulus at roughly a third of steel's; it defines the presence of a design framework and does not grade any aluminium member, span, deflection limit or installation in a delivered pergola. | ||
| aluminum-standards The Aluminum Association | Technical or regulatory context | United States | Standards or code directory 90 days | Automated retrieval succeeded (HTTP 200) The Aluminum Association 2024 standards-and-data page returned HTTP 200 on 2026-09-02 and its alloy, temper, mechanical-property and dimensional-tolerance scope was separately checked. It does not establish a pergola member, connection, system or site capacity. | ||
| usda-wood USDA Forest Products Laboratory | Technical or regulatory context | United States | Edition or archival record 365 days | Automated retrieval succeeded (HTTP 200) The registered US Forest Service Research and Development record page for the Wood Handbook (FPL-GTR-282, Wood as an engineering material) returned HTTP 200 on 2026-10-11 and was folded into the deflection-and-serviceability check group. The previous fpl.fs.usda.gov PDF address no longer served the document on a read-only recheck, so the official record page — which offers the current PDF download from the same record — was registered in its place. It is a government technical reference on wood properties, moisture, decay, fasteners and design; it is not a product capacity, a service-life figure or a project approval, and it establishes no pergola span or deflection limit. | ||
| awc-nds American Wood Council | Technical or regulatory context | United States | Edition or archival record 365 days | Automated retrieval succeeded (HTTP 200) The registered American Wood Council 2024 National Design Specification for Wood Construction page returned HTTP 200 on 2026-10-11 and was folded into the deflection-and-serviceability check group. It is the United States design standard for wood members and connections that the model codes reference; it supplies the design-value framework for members and connections and does not itself assign a span, a deflection limit, a product capacity or a project approval. | ||
| eurocode-1 European Commission Joint Research Centre | Technical or regulatory context | European framework | Standards or code directory 90 days | Automated retrieval succeeded (HTTP 200) The registered European Commission Joint Research Centre Eurocode 1 page returned HTTP 200 and was read on 2026-10-15. It describes actions including self-weight, imposed, snow and wind and the role of National Annexes and nationally determined parameters. It is an official framework entry point, not a calculation, capacity result, fixing layout or project approval. | ||
| iso-12944 International Organization for Standardization | Technical or regulatory context | International or global | Edition or archival record 365 days | Automated retrieval succeeded (HTTP 200) The automated client received HTTP 200; this does not validate content, edition or current applicability. | ||

| uk-planning UK Planning Portal | Technical or regulatory context | England | Living web guidance 180 days | Automated retrieval succeeded (HTTP 200) The registered UK Planning Portal England FAQ page on whether planning permission is needed for a pergola returned HTTP 200 on 2026-10-09 and was folded into the UK-planning check group. It states that a pergola is classed as permitted development provided it meets specified conditions and limits, notes that outbuildings cannot be installed on the principal elevation and that any platform must not exceed 0.3 metres, and directs a listed building to listed building consent and planning permission. It is England-facing plain-language guidance: it states no project determination, no wording of the class limits themselves and no rule for Wales, Scotland or Northern Ireland. | ||
| govuk-householder-permitted-development UK Ministry of Housing, Communities and Local Government | Technical or regulatory context | England | Living web guidance 180 days | Automated retrieval succeeded (HTTP 200) The registered GOV.UK householder permitted-development technical guidance (updated 10 September 2019; applies to England) returned HTTP 200 on 2026-10-09 and was folded into the UK-planning check group. Its Class E limits and conditions, the raised-platform definition of a height greater than 0.3 metres, the exclusion of verandahs, balconies and raised platforms, and the statement that buildings attached to the house are not permitted under Class E and are subject to Class A were used to write out the England tests. It decides the class framework only: it does not determine a project, approve a structure or apply outside England. | ||
| hse-work-at-height Health and Safety Executive (Great Britain) | Operational safety context | Great Britain | Living web guidance 180 days | Automated retrieval succeeded (HTTP 200) The registered Great Britain HSE Work at height: the law page returned HTTP 200 on 2026-10-12 and was folded into the self-build boundary check group. It states Great Britain duties for employers and people controlling work at height, including building owners contracting others; it is occupational-safety guidance, not a Czech or Slovak construction rule, trade licence, method statement or project approval. | ||
| lysaght-six-sided-gazebo-guide Lysaght | Technical or regulatory context | Australia | Edition or archival record 365 days | Automated retrieval succeeded (HTTP 200) The registered manufacturer installation guide returned HTTP 200 and its six-sided frame, crown, rafter, gutter, outlet and setting-out topology was checked on 2026-09-14. Its product dimensions, connectors, footings and approval notes do not establish a universal hexagonal-pergola design or local approval. | ||
| france-cre-pv-tariffs Commission de régulation de l'énergie | Technical or regulatory context | France | Living web guidance 180 days | Automated retrieval succeeded (HTTP 200) The registered CRE open-data page returned HTTP 200 and its quarterly revision boundary for metropolitan French photovoltaic tariffs, premiums and degressivity coefficients was checked on 2026-09-10.

| govuk-approved-document-k UK Ministry of Housing, Communities and Local Government | Technical or regulatory context | England | Standards or code directory 90 days | Automated retrieval succeeded (HTTP 200) The registered GOV.UK publication page for Approved Document K returned HTTP 200 and its publisher description — building regulation in England covering protection from falling, collision and impact in and around the building — together with its Details summary (this edition covers protection from falling, collision and impact and includes designing staircases, ladders, ramps, guarding and vehicle barriers in and around all types of buildings; since April 2023 the Building Safety Regulator has a duty under the Building Safety Act 2022 to keep under review the safety and standards of all buildings in England; the edition combines Approved Document N and some overlapping Approved Document M guidance) were read on 2026-09-26. Only the publication page and its summary were read: the PDF was not machine-extracted, so no clause text, guard height, load value or dimension is attributed to it. It is England-only guidance and does not determine whether any project needs approval or satisfies the requirement. | ||
| govuk-building-regulations-approval UK Government (GOV.UK) | Technical or regulatory context | England | Living web guidance 180 days | Automated retrieval succeeded (HTTP 200) The registered GOV.UK building regulations approval service page returned HTTP 200 on 2026-10-09 and was folded into the UK-planning check group. It states that building regulations approval is different from planning permission and that both may be needed, and that using someone registered with a competent person scheme removes the need for the householder to obtain approval separately. It is an England-facing process page: it does not decide a project, name an applicable edition or transfer to another jurisdiction. | ||
