Fremont ADU Permit Fees & Cost Calculator
Fremont’s official ADU page confirms a separate permit is required for the ADU, but the public page in the provided results does not expose a full fee schedule. For California ADUs, impact fees are waived for units under 750 square feet under state law, and larger ADUs may be subject to city-defined fees that must be verified directly with Fremont.

The calculator uses staged city data from the ADUFee database with visible confidence levels and dated source tracking.
Fee overview
The provided search results do not include Fremont’s current official fee schedule, so exact building permit, plan check, inspection, technology, and utility connection charges could not be confirmed.
One numeric fee in the results ($1,000 preapproved plan review) comes from a secondary source and should not be treated as confirmed official pricing without verification.
Impact-fee treatment for ADUs 750 square feet and larger may differ and should be checked directly with Fremont before budgeting.
The user wants ADU permit and pre-development fee data, not total construction cost estimates.
Fremont’s public-facing official ADU page in the provided results does not include a full fee table, so unverified dollar amounts are omitted.
California’s ADU impact-fee exemption for units under 750 square feet applies as the baseline unless a specific local fee is separately identified.
