When a Flagstaff permit entry names a model plan, keep both identifiers. The model identifies a reviewed design; the property’s permit identifies the work being authorized for a particular site. Start with the City’s monthly building permit lists to connect an address or parcel to a permit number, then request the underlying file if the relationship is unclear.
A real list shows why suffixes matter
In the City’s September 2026 permit list, the opening page lists BP-26-01629-01 as an attached ADU and names model plan BP-25-00928-01. The eighth PDF page separately lists BP-26-01629 for a single-family project and names model plan BP-25-00928. Both rows carry the same parcel and street address.
The useful lesson is to preserve the complete numbers and classifications. Do not remove “-01” as if it were formatting noise, and do not replace the site permit with the model-plan number. These published rows establish a record relationship to investigate; they do not establish that either unit has passed final inspection or received occupancy approval.
Search by the property, then collect every relevant identifier
- Choose the likely month from Construction Permit Statistics and open the building permit list, rather than a citywide statistical total.
- Use the PDF viewer’s Find command for the address or parcel/APN. The September list contains separate columns for permit number, classification, project name, parcel and address.
- Check the full row and any continuation. Preserve the site permit, complete parcel number, address, project classification and any additional plan or case number mentioned.
- If the main residence and an ADU have different records, keep both. Ask which documents apply to each space instead of treating one property-level match as the entire history.
The current statistics page links to 2025–2026 monthly lists and 2023–2024 archives. Those visible ranges do not establish the earliest City permit or complete coverage of older buildings. If a date or address is uncertain, ask for the historical index rather than assuming a more recent list is the beginning of the file.
What a pre-approved model does—and does not—establish
The City’s separate library for detached ADU models illustrates the distinction: a pre-reviewed design still needs a lot-specific permit, followed by construction and occupancy approval. Its same-as review checks site fit, access and utilities. This library does not establish which model program the two attached-project entries above used.
Keep design, site authorization and completion evidence separate. A model name in a sales description does not supply the site’s approval record, and a similar-looking building does not identify its approved design.
The library also says an ADU receives a separate address during permit review. If an older record uses the main-house address, retain it as a search lead alongside the later ADU address and parcel number. Do not silently discard one identifier because the other is newer.
Use Citizen Access for the current workflow; request the historical documents
City Building Safety issues permits and directs requests for permit copies to Public Records. Its Building Permits page directs current applications to Citizen Access. Our portal check reached a JavaScript requirement, so no public address/APN query or returned project was verified there.
For missing or older files, use the City public-records request page. The City Clerk receives these requests and explains that the City is not required to create new documents. Request existing records that identify the relationship you need:
- The permit and approved site plan for the exact address or ADU, including its complete permit number.
- The model-plan reference and any approved site-specific revisions needed to understand that permit.
- The associated inspection history, final outcome and occupancy certificate, if those are the remaining questions.
- For an older address, any existing record that connects it to the current address or parcel.
If the request returns only a model sheet, identify the still-missing site permit rather than calling the file complete. For a no-result search, confirm jurisdiction and the address used when the permit was created. This guide concerns City of Flagstaff files; it is not a countywide permit index. The address-lookup guide covers those identity checks.
Official sources checked October 16, 2026 (UTC). We read the City’s department, request, report-index and model-library guidance, plus the cited entries on PDF pages 1 and 8. We did not run a live property search, open the underlying model or site-permit file, or verify completion of the example projects. A missing online record does not prove unlawful or unsafe work.
