Building permits in Laredo — the largest US city on the Mexican border, located in Webb County — are issued by Building Development Services. Laredo adopts the 2021 International Codes with local amendments.
This guide covers what requires a permit, how to apply, fees, trade permits, and inspections in Laredo.
Laredo is in Webb County on the US-Mexico border. The city handles all permitting within city limits. Laredo's rapid growth and international trade position make timely permitting essential for both commercial and residential projects.
What requires a building permit in Laredo?
Under the adopted 2021 codes, a permit is required for most construction activities:
Permit required
- New construction, additions, and alterations
- Structural modifications
- Reroofing, windows, siding changes
- Electrical, plumbing, and mechanical work
- Decks, pools, fences, and accessory structures
- Change of occupancy
- Demolition
- Mobile/manufactured home installations
Typically exempt
- Painting, flooring, and cosmetic work
- One-story detached accessory structure ≤ 200 sq ft
- Retaining walls ≤ 4 ft
- Same-type fixture replacements
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders. Note that exemption from a building permit does not exempt a project from zoning requirements — confirm edge cases with the building department.

Laredo trade permits
Electrical, plumbing, and mechanical permits filed separately. State-licensed contractors required.
Electrical permits
Required for service installations, panel upgrades, solar PV, and wiring — TDLR-licensed electrician required.
Plumbing permits
Required for plumbing, repipes, water heaters, and gas work — TSBPE-licensed plumber required.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, and ductwork — TDLR-licensed mechanical contractor required.
Miscellaneous & specialty
Pool, fence, sign, and demolition permits follow separate tracks.
Verify your contractor's license. Texas licenses electricians (TDLR), plumbers (TSBPE), and HVAC/mechanical contractors (TDLR) at the state level — contractors must register with the local municipality before pulling permits. Texas does not issue a statewide general-contractor license. Projects over $50,000 require a TDLR project number and accessibility review. The property owner is responsible for ensuring a permit is obtained. Verify trade licensure at tdlr.texas.gov and tsbpe.texas.gov.
