Plano Commercial Construction: 2024 Codes, Permits and Build-Out Timeline

Short answer: Plano adopted the 2024 International Codes (building, residential, existing building, energy, mechanical, plumbing, fuel gas, fire, property maintenance and pool codes) with local amendments, effective August 1, 2025, along with the 2023 National Electrical Code. A new commercial building needs an approved site plan and engineering release before its building permit can issue, and a filed final plat before its certificate of occupancy. The city's goal for first review of a commercial permit is 10 working days, and 5 to 7 working days for each resubmittal. A tenant finish-out skips the site and plat steps and can be submitted online.

Plano Is on the 2024 Codes

Plano's Building Standards Commission held a public hearing on the 2024 International Building Code on April 15, 2025, and the city adopted the 2024 editions by a series of ordinances numbered 2025-6-x, each "with certain additions, deletions, and amendments." The ordinances state an effective date of August 1, 2025. The electrical code is the 2023 NEC (Ordinance 2025-6-13).

That puts Plano a cycle ahead of Dallas, which is on the 2021 codes, and well ahead of Fort Worth, which still uses the 2015 IECC. Drawings prepared for a neighboring city are not automatically compliant in Plano. Two local amendments worth knowing early:

Sprinklers at 6,000 square feet. Plano's amended fire code requires automatic sprinklers in Group B (business) fire areas over 6,000 square feet, and in Group M (mercantile) where a fire area exceeds 6,000 square feet or combined M areas exceed 24,000. Groups A-1, A-3, A-4, E and F-1 also use 6,000-square-foot triggers. That is a lower threshold than many owners expect, and it changes the budget for a small office or retail building.

A toilet facility on every permitted site. Plano's IBC amendments require one, and the city says it may issue a stop work order on a project that does not comply.

Step 1: Pre-Application Meeting and Zoning

Plano's Development Handbook (February 2026) says "the development process begins with a pre-application meeting," scheduled through the Planning Department and attended by Planning, Engineering, Building Inspections, Environmental Health and Fire-Rescue. Bring the intended use, a concept plan and questions about utilities and access.

If the use is not allowed by the parcel's zoning, a rezoning goes to the Planning & Zoning Commission for a recommendation and then to City Council. The handbook says the process "takes a minimum of two months" from submittal to approval.

Step 2: Site Plan, Plat and Engineering (New Buildings)

For a new building, the city's order is fixed: concept or preliminary site plan, then site plan, preliminary plat and engineering plans, then public improvements, then building permits, then final plat, then certificate of occupancy. In the handbook's words, "site plans must be approved before building permits can be released and final plats must be approved and filed for Certificates of Occupancy to be released."

Plats are on a state clock: the handbook notes that state law requires plats to be acted on within 30 days of submittal, and a pre-submittal option lets many plats be approved by the Planning Director rather than the Planning & Zoning Commission. Building code, mechanical, electrical, plumbing and health plan review run at the same time as site and civil review, so the building drawings do not have to wait for engineering to finish, but the permit cannot issue until the "Full Civil Release" has been approved by Planning and Engineering. Plano offers a "Foundation Only" early-release permit.

Impact fees. The February 2026 handbook states that Plano does not require impact fees. Confirm any utility connection or meter fees with Engineering.

Step 3: Building Permit Submittal and Review

New buildings and additions are submitted to Building Inspections with the application, a plan review deposit of 65 percent of the commercial permit fee, and two sets of scaled, dimensioned plans (three for food businesses), per the city's permit guide. Drawings marked "bid set" are not accepted, and an incomplete submittal is rejected at the counter.

Tenant finish-outs and alterations can be submitted online. Commercial interior finish and commercial alteration/remodel are the only two permit types Plano accepts electronically. The submittal requirements include sealed drawings, a COMcheck compliance sheet, proof of the TDLR accessibility submittal, an asbestos survey, and a parking analysis if the use is changing.

Review goals. Plano's goal is 10 working days for comments on a first commercial review and 5 to 7 working days for the second and third reviews. Each correction cycle adds a review plus your design team's response time.

Third-party review. For commercial projects, Plano offers a Third-Party Organization plan review option to expedite review. Time and terms are negotiated between the applicant and the approved consultant, and the consultant's fee is on top of the city's.

Fire and health. Fire sprinkler and fire alarm plans go to Plano Fire-Rescue and must be approved before any framing inspection. Food-related build-outs send a plan set to Environmental Health for its own review, and a food business cannot open until it has a certificate of occupancy.

Contractor registration. Plano requires the general contractor to register with the city, and the mechanical, plumbing and electrical subcontractors to be validated on the permit, before it issues. Electrical contractors register listing a master electrician; plumbing and fire protection contractors need their state license. UTS BuildPros does not self-perform trades; licensed subcontractors pull and validate on their own permits.

Once issued, a permit allows 180 days to begin work.

Step 4: Inspections and the Certificate of Occupancy

Inspections are scheduled through eTRAKiT, SelecTXT or by phone at 972-941-7140. For a certificate of occupancy, Plano's CO sheet sets the order: electrical (power on before fire), fire, health, gas test, planning, then the final CO inspection, and "a Certificate of Occupancy will not be issued until all inspections have been scheduled and passed."

Plano requires a certificate of occupancy for a change of ownership, a change of tenant and a business name change, not only for new buildings. A new tenant moving into existing space needs one even if no construction is planned.

What Sets a Plano Timeline

Plano does not publish an overall project duration, and we do not quote one without your scope. What the city does publish are the clocks that sit inside it: a rezoning of at least two months, plats acted on within 30 days, 10 working days for a first commercial review and 5 to 7 for each resubmittal. Add design time before submittal, correction cycles, and construction. For how the construction phases themselves usually run, see our commercial construction timeline.

For a finish-out: no site plan or plat, online submittal, review, construction, then the inspection sequence and CO. The schedule usually turns on how complete the drawings are, long-lead items such as HVAC equipment and storefront, and whether the 6,000-square-foot sprinkler triggers apply.

For a new building: pre-application, zoning if needed, site plan, plat and engineering, and civil release come before the building permit. That front end usually sets the schedule more than the building review.

How We Work in Plano

Plano is next door to our Richardson office. We check zoning, sprinkler triggers and the code edition during preconstruction, prepare complete submittals with the design team, and schedule the licensed trades and their registrations. See our Plano general contractor page, our tenant build-outs and ground-up construction services, and how permitting works in Dallas and Fort Worth. Call (940) 231-2640 or request a consultation.
