What is Ar Apartment Questionnaire – Boulder County, CO?
The Ar Apartment Questionnaire is a rental survey issued by the Boulder County Assessor that collects rent, vacancy, unit-mix and amenity information for one rental property, identified by the property address listed on the accompanying letter.
The cover letter explains the purpose. The rental information is used in a mass appraisal analysis to establish market trends, which the Assessor says helps ensure that fair and equitable values are placed on all rental properties. The letter is dated 12/18/2024 and is signed by the Boulder County Assessor.
The survey has eleven numbered items, followed by a "completed by" line and a contact number:
- Property address, total number of buildings and average vacancy rate (items 1 to 3).
- Condition and remodel year, with a description of the remodel if there was one (items 4 and 5).
- Unit counts by type, from studios to 4+ bedrooms, with baths, average rent and average square footage (item 6).
- Sleeping rooms, tenant-paid utilities, off-street parking, laundry and additional amenities (items 7 to 11).
The form is not a tax return, a petition or an application for a classification. It asks for information only. Other Assessor questionnaires, such as the Online Income and Expense Questionnaire and the Hotel-Motel Income Questionnaire, are listed separately on the Assessor's forms page.
Who needs to file Ar Apartment Questionnaire – Boulder County, CO?
The Boulder County Assessor addresses the questionnaire to the property owner of the rental property whose address is listed on the letter. If you received the letter and survey, you are the person the Assessor is asking to complete it and return it to the office.
The letter does not name any penalty and does not describe the survey as a legal requirement; it asks for participation and says that participation is greatly appreciated.
Someone else may fill in the form for the owner: the form ends with a "COMPLETED BY (please print)" line and a contact number, so the person who completes it prints their name and gives a phone number. The letter does not describe any signature or power-of-attorney rule.
The questionnaire covers one property address. It is built for properties with rental units, and it includes a separate question for units rented as sleeping rooms (rent bedroom only, with use of a community kitchen and bath). If you need help with the form, the letter gives the Assessor's phone number and email address.
When to file Ar Apartment Questionnaire – Boulder County, CO
Return the questionnaire after you receive the Assessor's letter. The letter asks you to provide the information to the Assessor's Office as soon as possible and gives no calendar due date. The letter's own deadline line is incomplete, so check the date with the Assessor's Office at (303) 441-3530 if your copy shows one. The survey sets no recurring renewal or validity period. The letter does not state a processing time or a follow-up step.

- Circling only one utility or amenity when the form says "circle all that apply" for utilities paid by tenant (item 8) and additional amenities (item 11).
- Entering a remodel year in item 5 without describing the extent of the remodel on the lines below it.
- Leaving the unit-count table in item 6 incomplete: each unit type has its own count, baths, average rent and average square footage.
- Counting rooms rented individually as regular units instead of answering item 7 about sleeping rooms, with their number and average rent.
- Forgetting to print the name of the person completing the form and a contact number at the bottom.
- Filling out the survey for an address other than the property address listed on the Assessor's letter.
