Elk Grove ADU fee questions

Does an Elk Grove ADU of exactly 750 sq ft owe an impact fee?

Government Code section 66311.5(c)(1) bars impact fees on an ADU with 750 sq ft of interior livable space or less. The City's Measure A booklet prints under-750 and over-750 buckets, so ask the City to apply the current state-law boundary.

When do Elk Grove Unified school fees start?

Elk Grove Unified School District exempts ADUs of 750 sq ft or less. Its Facilities and Planning page publishes the larger-unit residential rate shown above; use it for an estimate and confirm the project-specific bill with the district.

Does the impact-fee exemption also remove permit fees?

No. Government Code section 66311.5(c)(1) addresses impact fees. Elk Grove's fee booklet has separate permit and impact schedules, but the area research did not verify a project-specific permit total; ask the City of Elk Grove Planning Division.

Is this a permit, or a plan I can build from?

Neither. It is a screening from public records, not professional advice, and not a survey, soils report, appraisal, loan offer or permit; every number is an estimate. A licensed designer confirms the final plan, and your city or county gives final approval.
