How do I combine or split my property?

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.
