Portland, Texas Building Permit Guide

Building permits inside Portland city limits come from the City’s Development Services Department at the City Annex, 601 Moore Avenue (361-777-4550), and are applied for in the City’s iWorQ portal or on the lobby computer at the Annex.

A permit is needed to build, alter or enlarge any structure, including swimming pools and fences, and to install, alter, repair or replace electrical wiring, plumbing or mechanical equipment. The City issues these permit types:

Portland Development Services: who handles permitting

All permits are issued by Development Services, which also runs planning and zoning and inspections. Plans for new construction are reviewed by Bureau Veritas under a professional services agreement with the City. Averi DeVault, P.E., is Director of Development Services.

The City’s Chief Building Official, at the same 361-777-4550 number, is listed in the state floodplain directory as Portland’s floodplain administrator. Portland lies in San Patricio County, with a small unpopulated part in Nueces County; land outside the city limits is outside the City’s permit system.

Portland applications, forms and contractor registration

Permits are issued in the name of the property owner or of the licensed contractor doing the work. Contractors register each calendar year (January 1 to December 31) in the iWorQ contractor portal with proof of their state licence and insurance; the registration number becomes the access code for booking inspections. Working for pay on a permitted job without registering is a misdemeanor punishable by a fine of up to $500 a day.

The Development Forms page posts the City’s supporting documents:

• Address assignment and verification, and the homestead affidavit
• Commercial plan submittal requirements and plan review checklist
• Electrical, gas and generator one-line diagrams
• Foundation certificate and wind brace report
• Asbestos statement and backflow prevention test form
• Swimming pool packet
• Short-term rental and bed and breakfast application

The City’s Permit Requirements and Inspection Checklist lists the documents and inspections for every permit type; incomplete applications are not accepted.

Portland permit cost

Fees come from the Development Fee Schedule, updated March 14, 2024. Small residential jobs are flat fees:

New buildings, additions, remodels and demolitions are charged by project value, which must be at least 80% of the International Code Council’s building valuation data and includes all building systems and site work. New single-family, multi-family and commercial projects also pay a plan review fee from a second table, and a technology fee is charged on top. For a project valued at $250,000, the building permit fee is $1,150 plus 150 × $6.50, or $2,125, and the plan review fee is $450 plus 150 × $2.50, or $825.

Multi-family and commercial projects also pay fire code plan review and inspection fees, starting at $500 and $750 for projects up to $250,000.

Portland trade permits

Plumbers, irrigators, electricians and air-conditioning contractors need state licences as well as City registration. Mechanical permits need a 2021 Manual J, S and D load and duct design, plumbing tunnel jobs need an engineer’s letter, irrigation permits close with a backflow test report, and generators need the gas and electrical one-line and the generator manual. Fire sprinkler, suppression and alarm systems are reviewed by the Fire Marshal.

What to submit for a new home

Any foundation over 1,000 sq ft must be designed and inspected by a Texas-licensed professional engineer, and new or remodeled assembly, educational, hazardous, institutional and R-1 and R-2 residential occupancies must be designed by a registered design professional. Commercial projects add engineered fire plans, a code analysis sheet, a 2021 COMcheck and a stormwater notice of intent.

Inspections in Portland

Contractors request inspections in the iWorQ citizen portal, using their registration number as the access code and choosing a morning or afternoon visit. Requests in by 4:00 p.m. are scheduled for the next business day; later requests go to the next two business days. Results are posted in the portal by the end of the business day. If an inspection is missed, the City requires an engineer’s letter to sign off the work.

The checklist lists 23 inspections for a new home: setback, temporary electric pole, plumbing rough, water service and sewer yard, foundation, electrical, mechanical and gas rough, plumbing top-out, framing, stucco and brick ties, energy insulation, construction electric and gas final with meter release forms, the trade and building finals, energy final, the driveway flatwork (by Public Works) and a certificate of occupancy walkthrough with the Building Official. Framing inspections do not replace the Texas Department of Insurance windstorm inspections.

Local Portland details

Windstorm: roofing, windows, siding, doors, accessory structures, solar panels and generators all need the TDI WPI-1 at application and the WPI-8 certificate before the permit closes. During a hurricane warning, the Building Official can order loose outdoor objects and building materials on homes, businesses and construction sites to be secured or stored.

Flood zones: the City’s flood hazard areas come from the Flood Insurance Study for the City of Portland dated November 4, 2016, and new homes close out with an elevation certificate.

Certificates of occupancy: a new CO is needed for each new tenant, new use, business name change or change of ownership, and utilities are released in the new tenant’s name only after it is issued.

Land next to state land: work on land adjoining state-owned or General Land Office land needs a boundary survey by a licensed state land surveyor.

Texas building code

Texas has no single statewide building code: state law makes the International Residential Code the base code for homes in cities and the International Building Code the base for commercial buildings, with each city choosing the edition and its own amendments, while the National Electrical Code and the energy code apply statewide. Outside city limits most counties issue no building permits for homes. Texas building code rules
