Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
N/A; Cameron County publishes application requirements and inspection stages but no standard building-plan review timeline. OSSF permit letters are issued after the Designated Representative reviews and inspects the submission.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call 956-247-3516 (Building Permits); 956-247-3599 (Environmental Health/OSSF); 956-247-3500 (County Engineer) if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.

N/A; Cameron County publishes application requirements and inspection stages but no standard building-plan review timeline. OSSF permit letters are issued after the Designated Representative reviews and inspects the submission.
Submit the building permit application and plans to the Planning and Inspections Division at 1390 W. Expressway 83, San Benito, or contact 956-247-3516. County inspections include underground plumbing, foundation, framing, insulation, and final inspections; concealed work must not be covered before acceptance, and at least two whole business days’ notice is required for certain electrical inspections. After-hours requests must be submitted at least 72 hours in advance. For OSSF, obtain the building clearance letter, soil/site evaluation and design, submit the checklist to Environmental Health, and contact 956-247-3599; the Designated Representative issues the permit after review/inspection.
Cameron County’s Flood Damage Prevention and Building Regulations, adopted July 5, 2022 and amended through April 8, 2025, apply to all unincorporated areas. They incorporate FEMA’s February 16, 2018 Flood Insurance Study and FIRM/FBFM, county floodplain standards, applicable ICC and state codes, Cameron County Fire Marshal codes, NFPA 70 for electrical service, and the 2015 International Fuel Gas Code. The county requires the lowest finished floor generally 12 inches above BFE or 24 inches above highest adjacent grade, whichever is higher, with coastal/floodway and utility requirements. OSSF work follows Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285. No broad cosmetic-work exemption is published. The county requires a building permit before development in its jurisdiction. Temporary structures have Type I and Type II permit categories with defined terms. Subdivision platting exceptions include agricultural/farm/ranch/wildlife/timber uses, qualifying family divisions of four or fewer parts, divisions where all lots exceed 10 acres, and other statutory exceptions, but exempt divisions still require an affidavit and may remain subject to site-development, floodplain, building, and OSSF rules. Emergency utility repairs may proceed with next-business-day written notice to the Floodplain Administrator.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
