Miami, Oklahoma Building Permit Guide

Miami’s Community Development Department, 129 5th Ave. NW, issues building, electrical, plumbing, mechanical, roofing and demolition permits for property inside the city limits and has enforced the 2024 International Codes since October 1, 2026. A new house costs $150 for the first 1,000 square feet plus $5 per additional 100 square feet, and the city asks for 10 business days to approve a residential permit.

What needs a permit in Miami?

The city’s Permits page lists the work that generally needs a building permit, and the work that does not:

Zoning, stormwater and floodplain rules can still apply when no building permit is needed.

Who issues building permits in Miami?

Community Development covers building inspections and permits, contractor registration, floodplain management, zoning and the city’s maps and infrastructure. Travis D. Jones is the Community Development Director. The State Fire Marshal’s July 2026 list includes Miami among the cities that do their own plan review, permitting and inspections.

The city permits only inside its limits. Outside them, Ottawa County issues no building permits; its Emergency Management office, the county floodplain administrator, handles floodplain permits (918-541-9391). Buildings on the NEO A&M College campus come under Oklahoma State University, which the State Fire Marshal lists as reviewing and inspecting its own projects.

Miami permit applications

The applications are PDFs on the Permits page. File them with Community Development together with the plans:

• Building Permit Application for new buildings, additions, remodels, accessory buildings and carports, with a site plan drawing (Attachment A).
• Application for Electrical, Mechanical or Plumbing Permit, which lists each licensed contractor’s licence number.
• Application for New and Re-Roofing Permit, asking for the roofer’s Oklahoma licence number, the roof area and how many layers come off.
• Demolition Permit Application (August 2023 edition), with insurance and a performance bond unless the director waives them for an owner working on their own property, plus utility disconnects.
• Sign Permit, Storm Shelter Permit and Floodplain Development Permit applications.
• Soil and Erosion Control Permit: required for every construction project in the city, with an erosion control plan and fee.

Contractor registration: electrical, plumbing and mechanical contractors need a state licence and must also register with Miami, including contractors working outside the city on systems connected to the city’s electric, water or sewer service. Registration is $100 for a new contractor. The fee sheet gives renewal as $50 a year by June 30 ($100 after that), while the fee page of the Building Permit Application says $100 a year; ask which applies. Roofers register with the Oklahoma Construction Industries Board.

Miami building permit fees

Since July 7, 2015 Miami has charged building permits by square footage under Ordinance 1640; Ordinance 1641 added a penalty for not paying permit and inspection fees.

For example, a new 2,000 sq ft house costs $150 for the first 1,000 sq ft plus 10 × $5 = $50, so $200 for the permit plus the $4 state fee, before the inspection fees.

Electrical, plumbing and mechanical permits

Electrical, plumbing and mechanical work each need their own permit, and the trade permit fee includes the inspection: $50 per inspection, $95 per re-inspection, and $75 (residential) or $125 (commercial) for the final, plus the $4 state fee. A permit will not be issued without the contractors’ licence numbers. All feeders, branch circuits and service conductors attached to the city’s electric system must be copper (City Code Ch. 6, Art. IV, Sec. 6-100).

A home that has been without city utilities for a year or more cannot be reconnected until licensed electrical, mechanical and plumbing contractors each sign the city’s certificate of code compliance; a commercial version of the form applies to businesses.

What to submit

• The completed application with the owner, contractor and job address, estimated cost and square footage.
• A site plan showing the proposed work, existing utilities and distances to property lines; all structures need 10 ft of separation.
• Construction documents, plans and specifications.
• Licence numbers for the electrician, plumber, heat and air contractor and roofer.
• A floodplain determination (allow 3 business days) and, in the floodplain, a Floodplain Development Permit, with certified elevations for new construction and substantial improvements.
• For grading over one acre, a storm water control plan to the City Engineer under Section 10-66.

The city asks applicants to allow 10 business days for a residential permit and 21 to 28 business days for a commercial permit; an incomplete application delays issue.
