For a building permit in Douglas County, Colorado, first confirm who issued it. The County Building Division issues building permits for unincorporated areas. Its Building Online Services offers a public permit search by address or permit number. For some older permits, the County’s 1976–1985 register may be the remaining evidence of issuance even when the fuller file is unavailable.
Check the building jurisdiction before searching
An address in Douglas County does not automatically belong to the County Building Division. The County portal has a Search Address Jurisdiction form specifically to identify the building division for an address. It accepts a house number and/or street name; its instructions say to leave off direction letters and street-type abbreviations. If it points to a municipality, ask that municipal building office for its permit record rather than treating a County search miss as an absence of work.
This boundary matters for older files too: the County retention schedule describes records of permits issued by the County. A municipal permit would have a different custodian. Our city versus county permit records guide explains how to keep those searches separate.
Search with the address or permit number you have
The Simple Permit Search shows fields for permit number, street number, and street name. The short route is:
- If you have a printed County permit, enter its permit number. Otherwise, enter the street number and street name.
- Leave direction letters such as N or S and suffixes such as Ave or Dr out of the street-name field, as the form instructs.
- If a matching permit appears, open it and check its dates and inspection history rather than assuming issuance means completion.
A County inspection guide says this search does not require sign-in and that an opened permit can show Inspection History with a Print Report option. We reached the blank form, but did not run a search or inspect a result.
The Advanced Permit Search also exposes issued and completed dates, permit type and status, address fields, and a State Parcel Number field. Those are live form labels, not a promise that every archived record has each field populated. Use an official number or a narrow address first.
The Building Division page says its online services include more than 1.2 million archived building permit records dating back to 1978. That is an online coverage claim, not a guarantee that every document from 1978 onward is present or that an earlier permit never existed.
Ask for the right older record
The County’s Building and Structure Records schedule identifies a permanent 1976–1985 register or ledger listing issued building permits. It explicitly warns that the register may be the only issuance record for older permits. For a project believed to fall in that span, ask the Building Division about the register even if no complete permit packet appears online. A register entry can establish a recorded issuance; it may offer less detail than an application file, plan, or inspection report.
The register documents issuance, not the outcome of the work. If the question is whether construction was inspected or completed, ask separately for the inspection history or completion record. The schedule states minimum retention rules, not proof that a particular record was kept or digitized.
For a missing County record, contact the Building Division at 303-660-7497, or use the County’s records-request route for a specific County department record. Give the jurisdiction, address, approximate year, and permit number if known; ask specifically for the permit, 1976–1985 register entry, or inspection history. A result that is absent online leaves the underlying record question open. It also cannot establish current code compliance or completed inspections.
What the County keeps, and what an open records request costs
The County’s Building and Structure Records retention schedule sets different rules for different parts of a permit file:
- Building permits, certificates of occupancy, and inspection reports (both passed and failed) are kept permanently.
- Demolition permits are kept for 10 years after the demolition.
- Construction drawings for approved residential permits only have to be kept 180 days after the project is finished. Nonresidential plans for approved permits are kept permanently.
In practice, you can often confirm that a permit was issued and inspected on an older house, but don’t expect the County to still have its house plans.
Before you file a request, use the Advanced Permit Search to narrow results. You can search by State Parcel Number, Subdivision, Issued Date range or CO Date range. The Status filter includes Finalled, Completed, Expired, Historical and Voided. On a permit record, the Inspections History section has a Print Report button, as shown in the County’s paperless inspection reports guide.
If you still need a record, the Douglas County Open Records page sends requests for County department records to its County Department Records portal. The County responds within three working days, or up to seven more working days in extenuating circumstances. Under the County’s open records procedure and fees, research time can be charged at $40 an hour after the first hour, and standard copies cost no more than $0.25 a page. Fees are collected before the work is done.
