Ada, Oklahoma Building Permit Guide

In Ada, building permits come from the Community Development Department’s Building Division at City Hall, 231 S. Townsend, and are filed, paid for and inspected through the City’s GOVmotus web portal. Fees follow the value of the work under Resolution 26-12A, in force since July 1, 2026: $125 for the first $15,000 of a new building plus $1.35 for each further $1,000. Commercial and multi-family plans must clear the weekly Project Review Team before you apply.

What needs a permit in Ada?

The City’s permit table lists nine permit types, and a change of use needs its own permit. A new building, addition or remodel permit already includes the building, mechanical, electrical and plumbing work.

City ordinances do not allow an accessory building on a lot without a house, and buildings built off-site are generally not allowed unless specifically approved.

Who issues building permits in Ada?

The Community Development Department brings platting, zoning, planned unit developments, plan review, permits, inspections, floodplain determinations and code enforcement into one office. Its Building Division reviews plans, issues permits and inspects every structure for code compliance.

Land outside the city is in Pontotoc County, which the state code commission lists as issuing no building permits; the county’s Emergency Management Director handles floodplain permits there.

Ada’s web portal and contractor licences

You need a GOVmotus account before applying. In the application, describe the job (for example “Residential New Construction”), enter the construction cost for new construction, remodels, additions, accessory buildings, pools and signs, and give the square footage for new construction. Roofing, electrical, mechanical and plumbing contractors enter their Construction Industries Board licence number, and electrical, mechanical and plumbing contractors also enter their City of Ada licence number.

Every electrical, mechanical and plumbing contractor must be licensed with the City: $250 for a new licence and $80 for the annual renewal, with licences expiring on June 30. The application is on the City’s business licences page, and the Deputy City Clerk handles it (ext. 223).

Fees are paid in the portal by card or by ACH/eCheck, which carries no charge. Resolution 26-12A sets the card processing fee at 2% of the payment, while the City’s December 2025 portal guide still says 4%; cash is taken at the Building Department in City Hall during counter hours. No permit is issued until it is paid.

Electrical, plumbing and mechanical work in Ada

On a new building, addition or remodel, the trade work is part of the one construction permit, and the application must list every electrical, mechanical and plumbing subcontractor with their City and state licence numbers. The fee schedule also lists separate plumbing, mechanical and electrical permit fees of $50 each.

The City’s FAQ notes that only a licensed mechanical contractor may install an HVAC system. For a solar installation, a homeowner who lives in the house may do the electrical work once the structural statement and sealed electrical drawings are provided. Commercial electrical work follows the 2023 National Electrical Code on the City’s adopted-code list. For commercial buildings, fire suppression and fire alarm plans go straight to the Deputy Fire Chief.

Ada building permit fees

The City Council and the Ada Public Works Authority approved the current schedule (Resolution 26-12A) on June 1, 2026, effective July 1, 2026. Construction permit fees are based on the total value of the work and include building, plumbing, electrical and mechanical.

For example, the construction permit for a new house valued at $300,000 is $125 plus 285 × $1.35, or $509.75, before any plan review charge. The same resolution sets a $250 sewer tap and water taps from $1,400 for a ¾-inch connection.

Plans and documents for an Ada permit

Plans must be drawn to scale (¼ inch per foot is normal) in black ink with text at least 12-point; photographs and copyrighted plans for another address are rejected. Incomplete submittals are not accepted.

How to get a building permit in Ada

Ada inspections

Request inspections in the GOVmotus portal against the issued permit, choosing the inspection type and date; requests should be made at least one day ahead, and the system does not accept a same-day date (write in the comments box if you need one). The City notifies you by email or text when the inspection is scheduled. For a permit not issued through the portal, call 580-436-6300, ext. 240.

Each failed inspection that has to be repeated costs $30. A permit is cancelled if no progress is made or no inspection is called for in 180 days. For commercial buildings, the Certificate of Occupancy is issued once the building inspector has approved the plans and all inspections have passed; only then may the business open.
