Governing code

What code applies here

Austin Residential Code 2021 (2021 IRC with Austin amendments)

Austin City Council approved the 2021 I-Codes on June 3, 2021, effective September 1, 2021. Austin's local amendments are among the more extensive in Texas, particularly around energy and flood provisions — and surrounding jurisdictions like Round Rock, Cedar Park, and Georgetown adopt their own versions on their own timelines.

Who reviews it

Austin Development Services Department handles permitting inside the city limits. Travis County covers unincorporated areas, and the Hill Country jurisdictions west of the city add septic and slope considerations that rarely show up in a standard foundation letter.

Services

Letters we issue in Austin

  • Permit closure affidavits

    Open or expired permit with work already complete. A sealed affidavit documents that the finished work meets code so the jurisdiction can close the file.

  • Foundation certifications

    New slab, repair verification, or lender-required certification — sealed against the adopted code edition and the site’s actual soil conditions.

  • Manufactured home foundation letters

    HUD 7584 permanent foundation certification for FHA, VA, and conventional financing. Turns a mobile home into real property.

  • Structural modification & repair

    Wall removals, beam additions, truss repairs, and post-damage structural certification for permit or insurance purposes.

  • Construction verification

    In-progress or after-the-fact verification that completed work matches the approved plans and the governing code.

FAQ

Engineer letters in Austin

What building code applies to an engineer letter in Austin?
Austin Residential Code 2021 (2021 IRC with Austin amendments). Austin City Council approved the 2021 I-Codes on June 3, 2021, effective September 1, 2021. Austin's local amendments are among the more extensive in Texas, particularly around energy and flood provisions — and surrounding jurisdictions like Round Rock, Cedar Park, and Georgetown adopt their own versions on their own timelines.
How fast can you turn around an engineer letter in Austin?
Standard turnaround is 24–48 hours from the site visit or from receipt of documentation. Same-day site visits are available in Austin — we travel to the property, document conditions, and issue the sealed letter without waiting on a local subcontractor’s schedule.
Do I need a site visit, or can the letter be written from photos?
It depends on what is being certified and what the jurisdiction will accept. Some after-the-fact certifications can be supported by dated construction photos and permit records; concealed structural work and most foundation certifications require an on-site evaluation. We tell you which applies before you commit to a fee.
Is the engineer licensed in Texas?
Yes. Every letter is signed and sealed by a professional engineer licensed in the state where the property sits — in this case Texas. A seal from an engineer licensed elsewhere is not valid for a Texas permit.
Will the Austin building department actually accept an engineer letter?
In most cases yes, but acceptance is at the discretion of the authority having jurisdiction. Austin Development Services Department handles permitting inside the city limits. Travis County covers unincorporated areas, and the Hill Country jurisdictions west of the city add septic and slope considerations that rarely show up in a standard foundation letter. We write to the specific department’s expectations and, when a jurisdiction has a required form, we use their form rather than a generic letter.
What does an engineer letter cost in Austin?
Fees depend on scope, whether a site visit is required, and how much documentation already exists. We quote a fixed fee before starting — no hourly billing and no surprise change orders. Send the permit number and a short description and you will have a number the same day.
