Last updated: October 2026
These are the questions people ask us most about building permits in Austin, answered the short way first. This site is not a government agency; we estimate fees from the city's published schedule and point you to the official office for the final word. For the calculator itself, start on the home page.
How much does a building permit cost in Austin?
It depends on the project. A 2,000 square foot new home runs about $2,345.83 all in, a 400 square foot addition runs about $1,842.04, and a 10,000 square foot new office building runs about $7,146.07. The calculator at the top of this page runs the city's exact tables.
Where do I apply for an Austin building permit?
Online through the Austin Build + Connect portal at abc.austintexas.gov, or in person at the Permitting and Development Center, 6310 Wilhelmina Delco Drive, Austin, TX 78752.
How long does Austin plan review take?
Published industry timelines put standard review at roughly 15 to 25 business days per cycle. Expedited plan review is available for qualifying projects.
Do I need a permit for a remodel in Austin?
If the work touches electrical, plumbing, mechanical, or structural elements, yes. Purely cosmetic updates generally do not need one. When in doubt, call 512-978-4000.
Why does Austin charge twice, plan review plus permit fees?
That is simply how Austin structures it. Plan review covers the cost of reviewing your plans and is paid at application (non-refundable). The per-trade permit fees cover inspections and are paid when the permit is issued. Our calculator shows both so there are no surprises.
Who do I contact with questions about my Austin permit?
The main line is 512-978-4000, appointments are 512-978-4504, and payments are 512-974-7045.
Are Austin permit fees going up soon?
Fee amounts refresh every October 1 with the city's fiscal year, so the next update is expected October 1, 2026. We re-verify these numbers every September.
Is this an official city website?
No. This is an independent resource operated by Perfect Option MBC, LLC. We are not a government agency and we are not affiliated with the city. Every estimate is built from the city's published fee schedule so you can confirm the number at the source.
Is the estimator free?
Yes. The estimator and this guide are free to use, with no account and no sign-up. The details you enter are calculated in your browser and are not stored or sent to us.
How current are the fees?
We work from the fee schedule the city publishes, and we update our math when the city updates its schedule. Treat every result as a well-sourced estimate, and confirm the final figure with the city when you apply.
