The California Legislature approved a bill requiring local governments to disclose infrastructure fees and requirements within 30 days of permit applications for new housing.
Current law did not require cities to reveal all infrastructure obligations or costs, and governments were not required to provide or honor builder estimates.
Those late-stage surprises often made financing harder and limited homebuilding, because builders lacked complete cost information when setting budgets for new California housing projects.
The measure also barred local governments from adding requirements after the 30-day window unless they showed a specific public health or safety need.
The approved bill then headed to the governor's desk, with backers saying earlier disclosure and firmer deadlines would reduce project risk and costs.
