I am going to build a new garage/carport or add concrete/blacktop to my property, what will my taxes be?

If the Assessor’s RMV for the new addition is less than $10,000 the value will be added to the RMV only. Under M50 guidelines you will not be assessed or taxed for the additions under $10,000 unless they fall under the 5-year $25,000 category. Beginning in the 2024 tax year the new construction thresholds will be increased to $18,200 in any one year or $45,000 within any consecutive five years. Thresholds indexed annually starting with tax years 2025-26.
