Austin uses a split permitting workflow rather than routing every project through one online application. Austin Development Services handles the primary building-permit and plan-review functions, while land-use, fire, floodplain, transportation and other reviews may involve separate City work groups. Austin Build + Connect (AB+C) is central to permit management, payments, searches and inspections, but many residential and commercial building applications begin with project-specific City web forms.
Jurisdiction
Confirm Austin Jurisdiction Before Starting an Application
An Austin postal address does not by itself determine which development authority controls a project. City building requirements apply within Austin’s zoning jurisdiction, and City requirements can also extend to certain Municipal Utility Districts when the applicable consent agreement requires City permitting. Some electrical and plumbing work outside the City’s zoning jurisdiction can also fall under City requirements when City utilities serve the property.
Projects in Austin’s extraterritorial jurisdiction can have a different approval path and may require county approvals in addition to City land-development review. The jurisdiction and property status should therefore be established before choosing a building-permit application.
Austin-specific distinction
Building review, zoning review and site-plan review are not interchangeable approvals. A project can satisfy one review while still requiring another before construction permits can move forward.
Application path
Austin Uses Different Intake Routes for Different Permit Types
Residential
Residential Building Plan Review
New construction, additions, interior remodels and demolition involving single-family, duplex and other qualifying residential configurations are handled through Residential Plan Review. New applications are submitted using the applicable residential building-permit web form rather than assuming that AB+C is the initial application form.
Commercial
Commercial Building Plan Review
Commercial construction, commercial remodels, changes of use and qualifying multi-family projects use the Commercial Building Permit Web Form. The applicant also needs an AB+C account because project records, invoices and later permit activity are tied into the City’s online permit system.
Trade and stand-alone work
AB+C May Be the Direct Route
Many stand-alone trade permits can be requested directly through AB+C. Other stand-alone building permits use the City’s designated stand-alone application process. The correct route depends on the work rather than simply whether a contractor already has an AB+C account.
The City’s Types of Permits directory identifies the application method assigned to individual permit categories.
Residential projects
Residential Applications Move From Intake to Activation
Select the correct residential application
Residential Plan Review publishes separate application paths for project types such as new construction, additions, interior remodeling, demolition, fences and other residential work. Required plans and exhibits depend on the proposed project.
Check existing permit history
Austin instructs residential applicants to resolve expired building and trade permits before moving through the new review. Permit history can be checked through AB+C Public Search.
Submit the project through the applicable web form
After the City accepts an application for review, an invoice is issued. Review begins after the required payment is made and the project is distributed to the applicable review disciplines.
Respond to plan-review comments
If reviewers identify corrections, Austin issues review comments that must be addressed before approval. Updated documents are submitted through the residential permit modification process, and a complete revised plan set may be required rather than only the changed sheets.
Activate permits before construction inspections
Approval of the plans does not by itself complete permit activation. Once required permits are created, the applicable contractor or authorized permit holder must complete the activation process before scheduling construction inspections.
Residential process change
For residential permit applications in October 2026, Austin Energy no longer requires the Building Service Planning Application as part of the residential permit submission process. Electrical-service requirements that apply later in a project remain subject to Austin Energy rules.
Four-unit housing
Four-Unit Projects Can Follow Different Review Divisions
Austin’s treatment of four-unit residential development depends on the building configuration. Four-unit developments within the City are exempt from the site-plan process, but the correct building-review division still matters.
- Four individual single-family residences, two duplex buildings and certain other detached or semi-detached four-unit configurations can remain under Residential Plan Review.
- A single fourplex building containing four separate dwelling units is submitted through Commercial Plan Review or the applicable expedited review process.
- Site-plan exemption does not remove the requirement to obtain the correct building permit.
Commercial projects
Site-Plan Status Is Part of the Commercial Permit Sequence
For most commercial building applications, Austin requires an approved Site Plan, Site Plan Correction or Site Plan Exemption before the building permit is issued. A commercial building and site plan can be reviewed at the same time when the project qualifies for concurrent review and the required concurrent-review request has been approved, but the necessary subdivision or site-plan approval must still be completed before the building plan can receive final approval.
Determine site-plan status
Establish whether an approved site plan already covers the proposed work, whether a correction is needed, or whether the work qualifies for a site-plan exemption.
Prepare the commercial building application
The application package is based on the project scope and the City’s published commercial submittal requirements. Projects can involve several review disciplines when land use, utilities, fire, accessibility or other regulations apply.
Submit the Commercial Building Permit Web Form
The City’s commercial web form accepts new commercial permit applications, revisions and updates. The applicant provides the email associated with the AB+C account so the application can be connected to the City’s permit system.
Pay the invoice and complete plan review
After intake accepts the application, the City provides the invoice and document-upload instructions. Payment through the applicable City payment process allows the project to be distributed for review.
October 2026 floodplain change
For commercial remodels and renovations, Austin replaced the former Floodplain Approval Letter used with the Site Plan Exemption process with a Floodplain Supplemental Form. The supplemental form is submitted with the commercial application rather than obtaining the former approval letter in advance.
Online permit system
What Austin Build + Connect Is Used For
AB+C serves as Austin’s online development and permitting account system, but its role changes by permit type. Registered users can perform several permit-management functions, while some initial building applications are submitted through separate City forms.
Registered account
Permit Management
- Apply directly for permit types offered in the portal
- Pay permit and review fees
- Upload project attachments where supported
- Manage permits connected to the account
- Schedule eligible building inspections
Public access
Permit and Case Search
AB+C Public Search does not require registration. It can be used to search development cases, permit history and related records, making it useful when checking existing permits before a new application or reviewing the status of a property.
Inspections
Building Inspections Can Be Requested Online or by IVR
Austin allows building inspections to be scheduled through AB+C or through the City’s telephone Interactive Voice Response system. Online scheduling is available only when the AB+C account is linked to the permit, the permit is active and required fees have been paid.
- The permit holder, general contractor, listed homeowner-contractor, trade contractor or authorized agent can schedule an inspection when properly associated with the permit.
- AB+C displays inspections available for an active permit and provides scheduling, cancellation and inspection-status functions.
- Telephone scheduling requires an IVR PIN, the permit number and the applicable inspection code.
- Austin states that inspections are usually performed about 24 hours after scheduling, although inspector workload can push the inspection to the next business day or as late as 48 hours after the request.
Inspection sequencing remains the responsibility of the permit holder and owner-general contractor. Required inspections vary with the building and trade work authorized by the permit.
Related approvals
A Building Permit May Depend on Other Austin Reviews
Land use
Zoning and Site Plan
Land Use Intake handles applications involving zoning, site plans, subdivisions and related land-development matters. A Site Plan Exemption is a zoning-compliance and small-development review that can be required before a building permit is filed or obtained.
Fire
Austin Fire Plan Review
The Austin Fire Prevention Division reviews applicable site plans, building plans and fire-protection system plans. Review can cover fire access, hydrants, sprinklers, alarms, smoke control, egress, hazardous materials and wildland-urban-interface requirements.
Floodplain
Watershed and Floodplain Requirements
Projects affected by Austin floodplain regulations can require additional documentation or review. Floodplain issues may affect both site development and building-permit processing and should be identified before relying on a standard permit path.
Historic properties
Historic Preservation Review
Permit applications involving historic properties or qualifying demolition work can be routed for Historic Preservation review. Some projects can receive staff-level approval, while others may be referred to the Historic Landmark Commission.
Public right of way
Transportation and Public Works
Construction affecting a driveway, sidewalk, curb, excavation area or other public right of way can require a separate right-of-way permit administered through Austin Transportation and Public Works. A building permit does not replace these approvals.
Utilities
Austin Energy and Austin Water
Utility-related development can require separate coordination with Austin Energy or Austin Water. The applicable utility process depends on matters such as new or changed electrical service, water and wastewater connections, taps and utility infrastructure.
Project closeout
Final Inspection and Certificate of Occupancy
Permit closeout depends on completing the inspections assigned to the project and resolving outstanding permit requirements. For new construction and major renovations that require occupancy approval, the City provides a Certificate of Occupancy after the applicable final inspection requirements have been successfully completed.
A Temporary Certificate of Occupancy has a separate City process for qualifying residential and commercial projects that need limited occupancy, stocking or furnishing before the final Certificate of Occupancy is issued.
