Austin ADU Permit Fees & Cost Calculator
Austin allows additional dwelling units and requires a building permit and separate address, but the provided official source does not publish a clear ADU fee schedule. The only numeric fee information in the search results is from non-official cost guides, so exact permit and pre-development fees should be verified directly with the City of Austin and relevant utilities.

Step 1 of 5: Location
The calculator uses staged city data from the ADUFee database with visible confidence levels and dated source tracking.
Fee overview
The provided official city source confirms process requirements but does not expose exact fee amounts in the excerpt, so this dataset is incomplete.
Non-official cost guides should not be used as the basis for permit budgeting without verification from the City of Austin.
Utility connection, school district, and county-specific charges were not verified from official local sources in the provided results.
The request is for an accessory dwelling unit on a residential property within Austin city limits, not unincorporated Travis County.
Only fees visible from the provided search results were included; no exact fee was invented.
Because the official Austin source excerpt did not show a fee schedule, fee amounts are left null unless a non-official estimate was explicitly labeled as such.
FAQs
Are Austin ADU fee estimates official?
No. ADUFee.com provides planning estimates only. Final fees are set by the city, utility providers, school district, and other agencies.
What sources are used for Austin?
The database stores city, state, utility, school, county, and other source links where available. Each estimate should still be verified locally.
Can ADU fees vary within Texas?
Yes. Permit, utility, school, inspection, and impact fees can vary by jurisdiction, parcel, project size, utility provider, and local interpretation.
