Codes, exemptions & field inspections

Build to the adopted code. Verify every exception.

This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.

Regulatory framework

The code baseline for Kendall County.

Kendall County's March 4, 2026 verification letter states that permits are required for all development in unincorporated areas, including buildings, structures, grading, paving, excavation, fill, storage, driveways, county right-of-way work, outdoor lighting, OSSFs, and residential or commercial site improvements inside or outside the floodplain. The Engineer's Office applies the amended Kendall County Development Rules, 2022 Flood Damage Prevention Order, dark-sky standards, road/drainage/infrastructure requirements, and OSSF rules under Texas Health and Safety Code Chapter 366 and 30 TAC Chapters 30 and 285. The Fire Marshal administers the county-amended 2021 International Fire Code and issues permits and occupancy/compliance certificates for covered multifamily and nonresidential development. The county has not adopted a single-family residential building code and has no zoning in unincorporated areas.

Inspection lane

Obtain the rural 911 address and county-road access permit first, then submit the development application, checklist, printed and PDF plans, dark-sky application, and any floodplain, drainage, well, septic, or commercial materials. Incomplete applications are not processed. For OSSF work, submit the county septic form, professionally sealed planning materials, site evaluation, and required recorded affidavit and maintenance contract for an aerobic system; await approval, call 830-331-8253 to schedule inspections, and leave the system uncovered. For covered Fire Code work, the engineer, architect, or ICC-certified building official performs sufficient construction inspections; at completion, email the signed/sealed final-inspection request to fire.marshal@co.kendall.tx.us, after which the Fire Marshal calls to schedule the appointment.

Minor-work playbook

Understand what may be exempt—and what is not.

There is no broad minor-development exemption: the county's 2026 letter says all man-made site-development changes require permitting. Kendall County expressly requires an OSSF permit regardless of acreage, eliminating the state 10-acre permit exception, and requires professionally prepared planning materials for all systems. An access permit is no longer required for a driveway fronting a private road, although an address request and the separate development permit still apply. Single-family residences are outside the county building-code program but are not exempt from development, floodplain, septic, driveway/address, dark-sky, or other applicable permits.

Field rule

A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.

Inspection pipeline

Keep the work visible at every release point.

  1. 1

    Request with lead time

    Obtain the rural 911 address and county-road access permit first, then submit the development application, checklist, printed and PDF plans, dark-sky application, and any floodplain, drainage, well, septic, or commercial materials. Incomplete applications are not processed. For OSSF work, submit the county septic form, professionally sealed planning materials, site evaluation, and required recorded affidavit and maintenance contract for an aerobic system; await approval, call 830-331-8253 to schedule inspections, and leave the system uncovered. For covered Fire Code work, the engineer, architect, or ICC-certified building official performs sufficient construction inspections; at completion, email the signed/sealed final-inspection request to fire.marshal@co.kendall.tx.us, after which the Fire Marshal calls to schedule the appointment.

  2. 2

    Preserve access

    Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.

  3. 3

    Close the record

    Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.

Contractor verification

Verify the builder before the contract is signed.

Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.

Planning reference

Keep the parcel rules beside the building plans.

A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Project questions

Frequently asked questions for Kendall County

Who handles permitting for this jurisdiction?

Kendall County Engineer's Office / Kendall County Fire Marshal's Office is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.

How should I begin an application?

No verified online portal was located in the reviewed public materials. Contact County Engineer: 830-249-9343 (development/OSSF direct line 830-331-8253); Fire Marshal: 830-249-3721 and request the current application route before preparing a final submittal.

How long might review take?

Kendall County expressly states that it will approve or deny an OSSF application within 30 days of receipt. The county publishes no typical development- or Fire Code-permit review duration; review begins only after the Engineer determines the application is complete.

How are inspections scheduled?

Obtain the rural 911 address and county-road access permit first, then submit the development application, checklist, printed and PDF plans, dark-sky application, and any floodplain, drainage, well, septic, or commercial materials. Incomplete applications are not processed. For OSSF work, submit the county septic form, professionally sealed planning materials, site evaluation, and required recorded affidavit and maintenance contract for an aerobic system; await approval, call 830-331-8253 to schedule inspections, and leave the system uncovered. For covered Fire Code work, the engineer, architect, or ICC-certified building official performs sufficient construction inspections; at completion, email the signed/sealed final-inspection request to fire.marshal@co.kendall.tx.us, after which the Fire Marshal calls to schedule the appointment.

Field sequencing matters

The inspector needs to see the work at the right moment.

Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.

When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.

Closeout file

Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
