Your physical address, which is also known as the situs address, is assigned by various divisions and jurisdictions, and not the County Assessor. Planning and Zoning is responsible for assigning, maintaining, and approving situs addresses in unincorporated Jefferson County.  We also receive situs address information from the various cities within the county. If you have a concern with your situs address, we would be happy to look into this on our end. Please call our office at 303-271-8600 and ask to speak to someone regarding a situs address concern. While the assessors office only maintains the information provided, you may need to contact the local agency or jurisdiction who is responsible for the assignment of the situs address.

The Assessor’s office is responsible for determining the actual value of your property. We revalue all properties every two years as ordered by state statute.  For example, in 2019 and 2020, we determined the market value of residential property by analyzing sales of properties that sold between July 1, 2016 and June 30, 2018. These dates are set by the state. Once these sales were verified, they were compared to the property being valued by a computer program and adjusted for size, age, date of sale, and amenities, such as bathrooms, garages, basements, porches, etc.  This adjusted value is what the Assessor’s Office believes is a reasonable market value for your property and is the value used by the Treasurer’s Office to calculate your taxes. We call this value the actual value.

Property taxes are calculated using this actual value by plugging it in to the formulas below:

Actual Value x Assessment Rate = Assessed Value 

• The actual value is the value explained above.
• The assessment rate is set by the state legislature. In 2020, the residential assessment rate was 7.15% and the non-residential assessment rate was 29%.

Assessed Value x Mill Levy = Taxes 

• The assessed value is the value calculated in the previous step. 
• The mill levy is determined by the school districts, county commissioners, and local taxing authorities such as fire departments, water districts, metro districts, and various other special districts.

Here is an example calculating the taxes of a $300,000 residence with 100 mills levy using the 2020 assessment rate:

• $300,000 X 7.15% = $21,450 
• $21,450 X 0.100 = $2,145.00 total taxes 

Taxes for like-valued properties will vary based on the specific mill levy for the tax district where the property is located, and taxes for properties in the same tax district will vary based on having different values.

As you can see, there are a number of reasons that your taxes could have gone up. However the most common reason that your taxes go up is that the value assigned to your property has increased.  The valued assigned by the Assessor’s Office will follow the pattern of market value of properties in your neighborhood.  As the value of homes in the neighborhood increase, so too does the value assigned by the Assessor’s Office.  If homes are selling for more, you home becomes more valuable, even if no changes have been made to your property. 

The appeal timeframe is May 1st thru June 1st each year.  It is important to review your Notice of Value sent every odd year to every property owner to determine if you agree with the Assessor Value.    

The Assessor’s Office transfers ownership by publicly recorded documents. These documents are recorded for public record at the Jefferson County Clerk & Recorder’s Office.

The Assessor’s Office changes its records based on changes in the real property records recorded in Jefferson County. Without a recorded document the Assessor’s Office is unable to combine parcels onto a single tax bill or split parcels. Please be aware even if a document is recorded in the real property records the Assessor’s Office may still be unable to combine the parcels onto one tax bill, and property owners may still receive multiple tax bills. Please note, this typically happens when the properties to be combined are not within the same taxing districts or the ownership and tenancy of parcels are not the same – as a result, the Assessor’s Office is unable to combine the tax bills. The Assessor’s Office is unable to provide legal advice as to which document you should record to effectuate a split or combination.

If you would like to pursue some type of action to combine or split your parcels, and your property is in unincorporated Jefferson County, please contact the Jefferson County Planning & Zoning Division and inquire about a property merger or a subdivision process. Jefferson County Planning and Zoning can be reached on the Jeffco Planning and Zoning website or at 303-271-8700.

If the property is located within city limits, you will need to contact the planning & zoning office for your city and inquire about a property merger or a subdivision process.

If your intent in requesting to combine parcels is to have an adjacent lot or parcel classified as residential for assessment purposes, the lot or parcels do not have to be combined to qualify. If you would like more information about this, please submit your question to our contact form, list your question as “Land and Agricultural,” and note that this is what you are asking about.

Property lines can only be determined by a surveyor. Jefferson County does not offer this service. If your property is within a platted subdivision, you may view the recorded plats at the Jefferson County Clerk & Recorder’s Office.  The Jefferson County Clerk & Recorder can be reached on their website or at 303-271-8122. The Jefferson County Assessor’s parcel maps can be viewed by locating the property in question through the Assessor Property Records Search Application.

When an owner on a deed dies, the death certificate may need to be recorded with the Clerk and Recorder. For more information on recording a death certificate, visit the Clerk and Recorder website or reach them at 303-271-8121. 

The rest of the process depends on what kind of ownership the property is.  

If the property is joint tenancy, the recording of a death certificate may result in the deceased owner being removed, but we still recommend getting legal advice from an attorney or probate court to be certain. 

If the property is tenants in common, the recording of the death certificate will not automatically result in the deceased owner being removed. You will need to contact probate court or an attorney to have the deceased owner removed. If a Personal Representative's Deed is recorded for public record, the Letters of Testamentary appointing the Personal Representative of the estate must also be recorded. The Assessor’s Office is unable to provide any legal advice.  Probate court can be reached at 720-772-2500 and is located at 100 Jefferson County Parkway Golden, CO  80419. 

We are unable to provide new schedule numbers before the plat, split, or deed is processed as they do not exist until that time. Plats, splits, and deeds will be worked in chronological order by recording date. With the Jefferson County offices previously closed due to COVID-19 we are working hard to address this backlog. We are unable to provide a time frame for when these documents will be processed. We appreciate your patience.

The Assessor’s Office is unable to provide legal advice as to which document you should record to effectuate a separation. If you need more in-depth information on separations, we suggest you contact a title company or a real estate attorney for more assistance.
