Building Permits in Plano

Plano requires a building permit for most construction, alteration, and repair work that affects structural, electrical, plumbing, or mechanical systems. Permits are issued by the City of Plano Building Inspections Department, which administers plan review, permitting, and field inspections for the city.

Plano has locally adopted construction codes based on the International Building Code (IBC) and International Residential Code (IRC) with local Plano amendments. Texas has no statewide mandatory building code for cities — House Bill 1736 (2021) established model minimum standards, but each municipality adopts and enforces its own codes. As a result, Plano's specific adopted code editions and local amendments govern all construction within the city.

Plano lies primarily in Collin County, with a small portion in Denton County. It is one of the most significant corporate-headquarters suburban centers in the country, with a substantial commercial and mixed-use development base alongside its residential neighborhoods, making building permit compliance a critical step for both homeowners and commercial developers.

When You Need a Permit

You generally need a Plano building permit for:

• New construction, additions, and accessory structures (including ADUs — Accessory Dwelling Units)
• Structural alterations, load-bearing wall changes, and foundation work
• Electrical, plumbing, and mechanical (HVAC) changes
• Reroofing and window or door openings in exterior walls
• Swimming pools, spas, and retaining walls above a height threshold
• Demolition of any habitable structure
• Changes of occupancy or use
• Garage conversions and covered patio additions

Minor cosmetic work — such as interior painting, floor coverings, and cabinetry replacement without plumbing or electrical changes — is typically exempt. When in doubt, contact the Building Inspections Department before starting work. Performing work without a required permit can result in stop-work orders, fines, required demolition of unpermitted work, and complications when selling the property.

Plano ePermits — The Online Portal

The City of Plano ePermits / Online Permit Center is the primary channel for permit applications, plan submittals, fee payments, and inspection scheduling. The portal is accessible through the Building Inspections Department page at plano.gov.

Through the ePermits portal you can:

• Submit new residential and commercial permit applications
• Upload construction documents for electronic plan review
• Track application and review status in real time
• Respond to plan check correction comments
• Pay permit fees online
• Schedule and track required inspections
• View inspection results and correction notices

The portal is available 24/7 for document submission and status checks. For projects not suitable for online submission, in-person service is available at Plano City Hall, 1520 K Ave., Plano, TX 75074. The Building Inspections Department can be reached at (972) 941-7320.

Permit Costs

Plano permit fees are established in the official Building Inspections Fee Schedule, published by the City of Plano. Fees are generally calculated based on:

• Building permit fee — scales with project valuation or project type
• Plan review fee — a percentage of or addition to the building permit fee
• Inspection fees — for each required inspection phase
• Impact and utility fees — may apply for new construction or additions that increase demand on city infrastructure

Because Plano is a fully developed, high-density suburban city with significant commercial activity, commercial permit applications for office, retail, and corporate campus projects often involve multiple review disciplines and corresponding fee components.

Do not rely on third-party fee estimates. Always consult the current Plano Building Inspections Fee Schedule linked in the sources for exact, up-to-date amounts before budgeting a project.

Typical Timeline

Second and subsequent correction cycles are typically shorter than the initial review if the applicant fully addresses all plan check comments. Using the ePermits portal to respond promptly to correction notices is the most reliable way to minimize review time.

The Process

1. Pre-submittal: Confirm the zoning district for your parcel and verify that your proposed use is permitted; review applicable adopted codes and Plano amendments; contact the Building Inspections Department for pre-application guidance on complex projects
2. Plans: Prepare construction documents — stamped by a licensed Texas architect or engineer where required — in the format specified by the ePermits portal (generally PDF)
3. Submit via ePermits: Create an account, start a new permit application, upload all required documents, and pay the initial plan review fee
4. Plan review: City reviewers across applicable disciplines (building, structural, electrical, mechanical, plumbing, fire, zoning) examine submitted plans for code compliance
5. Corrections: Respond to all plan check correction comments in the ePermits portal; revise and resubmit plans addressing each comment until all disciplines approve
6. Permit issuance: Pay remaining fees and receive the approved permit through the portal
7. Inspections: Schedule required inspections at each phase of construction through the portal or by phone
8. Final: Pass all final inspections; obtain a Certificate of Occupancy where required before occupying the structure

Inspections

Typical inspection stages for a residential project include:

• Footing / foundation
• Underground plumbing and electrical
• Framing
• Rough plumbing, electrical, and mechanical
• Insulation
• Drywall / sheathing
• Final building and trade inspections

For commercial projects, additional inspections — including fire suppression, accessibility compliance, and site utilities — are typically required.

Schedule inspections through the Plano ePermits portal or by contacting the Building Inspections Department at (972) 941-7320. Submit inspection requests at least one business day in advance. Inspection results and any correction notices are recorded in the portal.

Common Reasons for Denial or Corrections

• Plans do not meet Plano's locally adopted IBC, IRC, or other adopted code editions and amendments
• Missing structural calculations, energy compliance documentation (IECC), or required design-professional stamps
• Zoning conflicts — setbacks, height limits, lot coverage, or a use not permitted in the applicable district under Plano's Unified Development Ordinance (UDO)
• Missing utility clearances (water, sewer, electrical service from the appropriate provider)
• Fire marshal review not completed for commercial or multi-family projects
• Incomplete submittal — missing sheets, details, or required forms in the ePermits portal
• Property in a FEMA Special Flood Hazard Area without required floodplain development permit or elevation certificate
• HOA architectural review not completed (note: HOA approval is separate from city permits and does not substitute for them)
