- Cost approach — estimated replacement cost of improvements minus physical or functional depreciation.
- Income approach — capitalization of expected net income for commercial or rental properties.

When values change — reassessment triggers
Major reassessment events include change of ownership, new construction, and certain court or administrative adjustments. Under California law, assessments normally begin with a base-year value and adjust under rules set by the state and applied by the county assessor.
- Change of ownership — transfers can trigger reassessment to current market value.
- New construction — additions and substantial improvements are added to assessed value.
- Temporary reductions — market declines can lead to temporary reductions under state procedures.
