St. Joseph, Missouri Building Permit Guide

St. Joseph anchors north-west Missouri and runs an unusually granular building chapter, with its own classed electrical and mechanical trade licences, its own examinations and its own continuing education requirements. It is a municipal licensing regime of a depth the state itself does not provide.

The Building Development Services Department sits at City Hall, 1100 Frederick Avenue, open Monday to Friday 8 a.m. to 5 p.m. Permits are selected, completed and returned by post or fax, and staff give an approximate readiness date when a completed application is submitted. Plans submitted since March 2025 must be designed to the 2024 International Building, Existing Building, Residential, Mechanical, Fuel Gas and Fire Codes, the 2024 Uniform Plumbing Code and the 2023 National Electrical Code.

This guide covers work inside the St. Joseph city limits. Buchanan County and the surrounding communities adopt separately, and there are places called St. Joseph in other states.

What requires a building permit in St. Joseph?

Exempt lists, thresholds and fee schedules are set by whoever adopted the code, so an exempt list from a neighbouring municipality is not reliable and neither is one from the county. An exemption from a building permit is never an exemption from zoning, floodplain regulation, or an electrical or plumbing permit. Confirm scope with St. Joseph Building Development Services before work starts.

Local rules worth knowing

The city also bars permits on the enforcement side: its fee and permit article carries a provision headed no permits for contractors with violations, so an outstanding violation on one job can stop issuance on an unrelated one. Check the contractor’s standing before the bid, not after the award.

Missouri has no mandatory statewide building code for private construction: a county, fire protection district or municipality may adopt one (usually by reference under RSMo 67.280), and in parts of the state none has. Building codes in Missouri

Who handles permitting in St. Joseph?

Building Development Services issues building and trade permits, reviews plans and inspects work, with the city’s building chapter also establishing classed trade licensing for electricians and the mechanical trades, including examinations, experience and continuing education requirements.

The permit route is split by trade in a way that catches general contractors used to pulling everything themselves. The general contractor is responsible for obtaining only his own permit for the construction project — he cannot obtain the electrical, mechanical, plumbing or right-of-way permits. He does, however, need to be prepared with the information for all of them and a list of his subcontractors, all of whom must hold a current occupational licence with the city.

Electrical and plumbing work must be performed by a master electrician and plumber licensed by the City of St. Joseph, and those masters must carry a $2,000 bond in addition to workers’ compensation insurance, with copies of the bond and liability insurance provided to the department. On request the department can supply a list of licensed electrical and plumbing contractors.

In 2025, building permits issued in St. Joseph authorized 10 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Residential permits require an occupational licence obtained through the Customer Assistance Department and a copy of workers’ compensation insurance before the building permit can be obtained. Review time depends on the scope of work, the number of trades and whether the property sits in a flood zone. Over-the-counter permits are typically issued at the time of application.

How Missouri contractor credentials work

Commercial permits

Commercial projects of 20,000 cubic feet and larger, and all multi-family projects of three or more units, must have drawings prepared by an architect or professional engineer registered with the State of Missouri. Fence permits are issued through Planning and Zoning while roof permits come from the Building Department, so the counter differs by work type.

Licences, trade classifications and design professionals

Practically, three credential layers appear on Missouri projects: any local contractor licence or registration that applies where you are building; trade licences for electrical, plumbing or mechanical work (local, except that electrical can also be the optional state licence); and, on commercial and larger residential work, drawings sealed by a Missouri-licensed architect or professional engineer, whose licence is issued and enforced by the state. Confirm what St. Joseph Building Development Services requires for the specific building before filing.

For the main building trades Missouri licenses only electrical contractors at state level, through an optional licence that local governments must accept (RSMo 324.900 to 324.945); there is no state general, plumbing or mechanical licence. Contractor licensing in Missouri

St. Joseph permit costs and fees

Permit fees have been calculated on the valuation of construction since the first of July, 2022, following a council ordinance of the seventh of March that year which also increased construction permit and trade licence fees.

There is no state fee schedule for local building permits in Missouri, because there is no statewide code to charge against. Every figure is set by the adopting jurisdiction, which means a fee quoted for a project a few miles away may bear no relation to the fee here. Ask St. Joseph Building Development Services for the schedule in force on your filing date.

Fees for local building permits are set by whichever body adopted the code; Missouri has no state fee schedule for them. Permit fees in Missouri

Trade permits and who may pull them

Each trade follows the code the jurisdiction adopted for it; electrical contractors may hold the optional statewide licence, while plumbing and mechanical credentials are local. Trade permits in Missouri

How to apply for a St. Joseph building permit

Review, corrections and what actually causes delay

In Missouri the first cause of delay is filing with the wrong body — with the municipality where the parcel is unincorporated, with the county where the county never adopted a code, or with neither where a fire protection district holds the fire code. After that comes the edition question, because the jurisdiction chose its own edition and may be one or two cycles behind the current model code. Then missing local licensing, floodplain requirements along the state’s rivers, and seismic detailing in the south-east. There is no statewide review clock: any timeline you are given is that jurisdiction’s own target, not a statutory obligation. Build the review time into the schedule and confirm the checklist with St. Joseph Building Development Services before filing.

Permit validity is set by St. Joseph's ordinance rather than by statute, so confirm the expiry on phased or delayed work. Permit validity in Missouri

Inspections in St. Joseph

Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and any adopted energy provisions, fire systems on commercial work, and final, with an occupancy certificate before the building is used. Because the trades hold their own permits, their inspections are booked by the trade contractor rather than by the general contractor coordinating the job.

Missouri inspections are carried out against the edition the jurisdiction adopted and the local amendments it made to it, by inspectors employed or contracted by that jurisdiction. There is no state certification requirement for local building inspectors and no state body auditing them, so practice and interpretation vary more between Missouri jurisdictions than in states with a single code. Keep the approved plans on site for the inspector to check against, and confirm the notice St. Joseph Building Development Services needs and its inspection windows.

Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings and your correction responses available on site.

St. Joseph permit search and official resources

Permit records in Missouri sit with the body that issued them, and there is no state repository to fall back on. Where St. Joseph Building Development Services is the authority for the City of St. Joseph, it holds the building permit, the inspection history and the occupancy certificate. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — and in Missouri also confirm whether a permit was ever required, because in some places it was not.

These are the primary sources behind this guide. Ordinances, fee schedules and procedures change — confirm the position for your filing date.

Frequently asked questions

Can I start the foundation before plan review is finished?

Yes, if the city grants a footing and foundation permit on request. It allows the dirt work and foundation to proceed, but it is issued as a convenience contingent on approval of the final drawings, the applicant proceeds at their own risk, and the city gives no guarantee that a building permit will be issued. The partial permit is valid for 30 days and work may not go beyond the foundation under it.

Can my general contractor pull all the permits?

No. The general contractor is responsible for obtaining only his own permit and cannot obtain the electrical, mechanical, plumbing or right-of-way permits. He does need to be prepared with the information for all of them and a list of subcontractors, all of whom must hold a current occupational licence with the city.

What does an outstanding violation do to my permit?

It can stop it. The city's schedule of fees and permits carries a provision headed no permits for contractors with violations, so an unresolved violation on one project can bar issuance on another.

What do my electrician and plumber need?

A master licence issued by the City of St. Joseph, a $2,000 bond and workers’ compensation insurance, with copies of the bond and liability insurance supplied to the department. For the main building trades, Missouri has only one state licence: the optional statewide electrical contractor licence under RSMo sections 324.900 to 324.945, administered by the Office of Statewide Electrical Contractors, which began accepting applications on 1 July 2019. Under section 324.925 every political subdivision must recognise it in lieu of a local electrical licence; if one still refuses 30 days after the state notifies it of a complaint, its local sales tax revenue is held back until it complies. There is no state general contractor, plumbing or mechanical licence, so those credentials are local (city or county). Separately, where a city or county licenses construction contractors, section 287.061 requires it to obtain proof of workers’ compensation cover, or a signed exemption affidavit, before issuing the licence.

Which code applies here?

The city reviews plans submitted since March 2025 against the 2024 International Building, Existing Building, Residential, Mechanical, Fuel Gas and Fire Codes, the 2024 Uniform Plumbing Code and the 2023 National Electrical Code. Missouri has no mandatory statewide building code for private construction. A code applies to a parcel only because some body adopted one — a county, fire protection district or municipality — usually by incorporating a published model code by reference under the procedure in RSMo section 67.280. A copy of the adopted code is filed with the clerk of that community and kept available for public inspection. So the edition, the amendments, the exempt list, the fee schedule and the permit validity period are all local questions, and in some parts of the state the answer is that no code was ever adopted at all.

When do I need sealed drawings?

Commercial projects of 20,000 cubic feet and larger, and all multi-family projects of three or more units, must have drawings prepared by an architect or professional engineer registered with the State of Missouri.
