Building Inspections in St. Louis: Occupancy Permits, Code, and Who Shows Up
Revised September 11, 2026
What are the types of building inspections?
Three: the private inspection a buyer hires, which has no code authority; the municipal occupancy or housing conservation inspection, a minimum-standards code check the city requires before a unit is occupied; and the permit-stage construction inspections, footing through final, that verify permitted work rather than the condition of the house.
Keep reading ↓On a Thursday morning in Dutchtown, Marcus is nine days from closing on a brick two-family he has been circling since spring. The private inspector already walked it. The appraisal came back clean. Then the title company asks a question nobody had asked him before: is the occupancy inspection scheduled? It is not. He had never heard of it. In the City of St. Louis, the earliest an occupancy inspection can be scheduled is three business days from the day you apply, and the latest is fifteen days from the application day. Nine days suddenly looks like a very tight number.
Some version of that phone call happens in this city every week, and it is not because buyers are careless. It happens because three different things get called a building inspection, and only one of them is working for you.
One is the private inspection a buyer hires and pays for. One is the municipal occupancy inspection, a minimum-standards code check the city runs on its own behalf. One is the set of permit-stage construction inspections that happen during a build or a rehab. Different client, different scope, different consequences when something fails.
This guide walks all three: what each checks, who pays, what each one can and cannot force, and the order to do them in. Commercial occupancy is in here too, because that reader exists. If you want the buyer side in depth, our post on home inspections in St. Louis covers what a private inspection misses. This one is about the municipal track.
What are the types of building inspections?
Three, and they are not interchangeable. The private inspection is hired by a buyer, reports to that buyer, and carries no code authority whatsoever. The municipal occupancy or housing conservation inspection is a minimum-standards code check the city requires before a unit can be legally occupied. The permit-stage inspections verify permitted construction work at fixed points, from footing to final. Same two words, three different jobs.
The private inspection you hire
You pay for it, so it answers to you. A private inspector walks the house and writes you a report on condition: the roof, the furnace, the panel, the grading, the water heater, the things that will cost you money in year two. Nothing in that report obligates anyone. The seller can decline every request. The city does not see it, does not care about it, and will not act on it. Its value is leverage and information, not enforcement.
The municipal occupancy inspection
This one works for the city. It is a pass-or-fail code check against a minimum standard, and it gates whether a person may lawfully live in the unit. Failing it does not mean the house is bad. Passing it does not mean the house is good. It means the unit met a floor. That distinction is the single most misunderstood thing in this whole subject, and it costs people real money.
The permit-stage construction inspections
These belong to a project, not a property. When work is permitted, an inspector comes at set milestones to verify the permitted work matches code and matches the approved plans. Typical stages run footing, framing, rough electrical, rough plumbing, mechanical, then final. They verify the work that was pulled on the permit. They are not an opinion on the rest of the building, and they do not follow the house around after the permit closes.
What does the City of St. Louis occupancy inspection actually check?
It is a basic code inspection for minimal interior building code violations and minimum exterior standards under the International Property Maintenance Code. Ordinance No. 71835 requires a City Housing Conservation District Inspection of any property inside the district, and effective October 7, 2024, 100% of property in the City of St. Louis is located in a Housing Conservation District. There is no longer a part of the city where this does not apply.
So a house in Baden and a house in Holly Hills are on the same footing now. Whatever your block used to be outside of, it is not outside of this. For a buyer in Fox Park or Bevo Mill, that changes the question from “does my street need one” to “when do I apply.”
The inspection is required before a vacant residential unit is occupied, and before the sale of an occupied structure where no Certificate of Inspection has been issued in the last 12 months. For a residential sale, the Certificate of Inspection must be obtained before occupancy of the unit is permitted. For a rental unit, same rule: the certificate comes before occupancy. Nobody moves in on a promise.
A Certificate of Inspection is valid for 12 months. Rental dwelling units get reinspected every three years, or sooner on a change in occupancy. Owner-occupied properties are exempt from that three-year reinspection, which is a meaningful difference between buying a home to live in and buying a two-family to rent out. The inspection also establishes how many people may safely occupy the unit. No more than three unrelated persons may live in the same dwelling, and a family is defined as one or more persons living as a single housekeeping unit.
What does an occupancy inspection cost, and how long does it take?
The application fee is $120.00. If a resident is found occupying a dwelling without a current certificate, the fee is $200.00. Property managers pay $65.00 for each additional unit at the same address. On timing: the earliest an inspection may be scheduled is 3 business days from the day you apply, and the latest is 15 days from the application day. That window is the whole planning problem.
Read the second fee again. The $200.00 figure is what shows up when someone is already living there without a current certificate. It is not a penalty box you want to discover on a rental you just bought with a tenant in place, which is why the certificate history of an occupied building is worth asking about early rather than at the table.
Payment is its own small trap. The Housing Conservation office takes cash and checks only for in-person payment. Online payment is card only, and a 3.5% processing fee gets added. Neither is a hardship. Both are the kind of detail that turns a fifteen-minute errand into a second trip downtown if you show up with the wrong thing in your pocket.
Why is the city inspection not a substitute for your own?
Because the city says so, in writing. The City of St. Louis states plainly that “An inspection does not imply a guarantee or warranty as to the overall condition of the building and/or its systems,” and it advises that citizens purchasing property may want to consider having a commercial grade building inspection completed. The agency that runs the inspection is telling you to go get a different one.
That is not bureaucratic throat-clearing. It is an accurate description of scope. A minimum-standards check asks whether the unit clears a floor set by the property maintenance code. It does not ask how many winters are left in the roof, whether the electrical service is adequate for how you plan to live, or what the sewer lateral is doing under the front yard. A certificate on the wall and a habitable, non-expensive house are two separate claims.
So run both tracks. On the private side, shortlist two or three inspectors worth interviewing and tell each one plainly what you want: the crawl space entered rather than glanced at, the panel opened, the outbuilding included, a written report you can actually read, photographs, and a walkthrough at the end. Then listen to what each one says they are prepared to deliver. The gap between your list and their answer is the signal. Price moves with square footage, age, whether there is a basement or a crawl, how many units, and which add-on scopes you ask for, so compare scope and price together or you are comparing nothing.
If this is your first purchase, the sequencing matters more than any single line item. Our first-time homebuyer guide to St. Louis lays out where inspections sit in the larger timeline, and what a home appraisal involves in St. Louis explains the third visit people confuse with the first two.

What happens during permit-stage construction inspections?
An inspector comes out at fixed milestones while the work is open and verifies that what was permitted is what got built. The usual sequence on a build or a gut rehab runs footing, framing, rough electrical, rough plumbing, mechanical, and final. Each one happens before the next trade covers it up. Miss a stage and you may be opening a wall back up.
Here is the part rehabbers in Old North and Fox Park learn the hard way: these inspections verify the permitted work, not the condition of the house. A passed framing inspection says the framing you pulled a permit for meets code. It says nothing about the original joists twelve feet away that nobody touched. A final on a kitchen permit is a statement about that kitchen. It is not a clean bill of health for the building.
Which also means a rehabbed property is not automatically an occupancy-ready property. The construction permit track and the occupancy track are separate lines. Work that closed out cleanly on permits can still need its Certificate of Inspection before anybody moves in, and the clock on that certificate starts when you apply, not when the contractor finishes. Plan them as two errands, not one.
What does a commercial occupancy permit require in St. Louis?
More people than you expect. For commercial occupancy in the City of St. Louis, the inspectors who always examine a building are Building, Electrical, Mechanical, Plumbing, and the Fire Marshall. Air Pollution inspectors may be added depending on the business type, for example manufacturing or automotive painting. You apply in person at City Hall, Room 425, and someone has to be present between 9 a.m. and 2 p.m. to let inspectors in.
Bring paperwork that proves you are allowed to be there. Applicants must have a signed lease, or a notarized letter from the property owner granting permission to occupy and stating the type of business. Fees run $80.00 for units 3,500 square feet or less and $160.00 for units over 3,500 square feet. A name change on an existing permit is $5.00. If you pay the $80.00 and the space turns out to be over 3,500 square feet, you pay the additional $80.00 before the permit issues.
Zoning reviews the stated use first, before any of that. If zoning denies the use, a Conditional Use or Board of Adjustment hearing may be set, and that is a calendar event, not a phone call. If any inspector finds major violations, the applicant receives a violation letter, has to remediate, and then has to pass a re-inspection by the same inspector who wrote it. Watch the shot clock too: a commercial occupancy application is valid for 60 days, after which it is considered abandoned.
One more thing worth knowing before you sign a lease on a storefront in Carondelet or on The Hill. An occupancy permit is valid for a business until the business changes, the business owner changes, or the property’s use changes. The permit on the wall belonged to the last tenant. It does not transfer to you because the walls did not move.
What changes when the property is outside the city limits?
Everything on the municipal side is local. The rules above are City of St. Louis rules, and they stop at the city line. Every municipality in the region sets its own occupancy requirements, its own fee schedule, its own inspection triggers, and its own timelines. Some require an occupancy inspection on every sale. Some require one only on rentals. Some handle it very differently.
A house in Byrnes Mill or House Springs answers to a different city hall than one in Pine Lawn, Velda City, or Bellefontaine Neighbors, and none of those answers to the City of St. Louis. Do not assume, and do not take a neighbor’s experience from a different town as gospel. Call the municipality the property actually sits in, ask whether an occupancy or point-of-sale inspection is required, ask what triggers it, and ask what the current fee and lead time are. Fifteen minutes on the phone beats a rescheduled closing.
How to sequence it around a closing date
Work backward from the day someone needs to sleep in the house. In the city, the occupancy inspection cannot be scheduled sooner than 3 business days after you apply and no later than 15 days from the application day. Build that window into the contract timeline rather than discovering it in the last week.
A workable order looks like this. Under contract, confirm which municipality governs the property and what it requires. Book the private inspection immediately, inside your inspection period, because that is the window where you still have negotiating room. Ask the seller whether a Certificate of Inspection has been issued in the last 12 months, since that answer decides whether a fresh one is required at all. Apply for the occupancy inspection as soon as you know you need it, and pay attention to how you are paying.
Then leave slack for the thing that goes wrong. A failed item needs a repair and a re-inspection, and repairs need a contractor with an opening. Renovating? Run the permit-stage inspections on their own track and do not let a final on a kitchen permit convince you the occupancy step is handled. Two lines, two calendars.
Marcus, from the opening, made his closing. He applied the same afternoon, got an appointment on day four, and spent the two days before it fixing three small things a contractor could knock out in an hour. He got lucky on the calendar. The cheaper version of that story is applying two weeks earlier.

Frequently asked questions
What are the three main types of inspections?
The private inspection a buyer hires, which reports to the buyer and carries no code authority. The municipal occupancy or housing conservation inspection, a minimum-standards code check a city requires before a unit may be occupied. And permit-stage construction inspections, which verify permitted work at milestones like footing, framing, rough electrical, rough plumbing, mechanical, and final.
What is the checklist for building inspection?
It depends which inspection. The City of St. Louis housing conservation inspection checks for minimal interior building code violations and minimum exterior standards under the International Property Maintenance Code, and it establishes how many people may safely occupy the unit. A private inspector’s checklist is far broader and covers condition, systems, and remaining service life. Ask the municipality for its own list.
How many inspections are required when building a house?
There is no single number, because it depends on the permits pulled and the municipality. A typical permitted build or gut rehab hits footing, framing, rough electrical, rough plumbing, mechanical, and final, with each stage happening before that work gets covered. Ask the permit office for the inspection sequence tied to your specific permits before the first trade starts.
What do inspectors look for in an inspection?
A city occupancy inspector looks for code violations against a minimum standard and for safe occupancy limits, not overall quality. A permit-stage inspector checks that the permitted work matches code and the approved plans. A private inspector looks at condition and cost: roof, systems, structure, moisture. Three different questions, and only the private one is asking what the house will cost you.
Can a building inspector walk onto your property?
It depends on the situation, and it is worth asking your municipality rather than assuming. An inspection you applied for is one you invited, and for commercial occupancy in the city someone must be present between 9 a.m. and 2 p.m. to let inspectors in. Observing exterior conditions is different from entering a dwelling. Rules vary by municipality, so ask directly.
Can I say no to an inspection?
You can decline a private inspection, since that one is yours to buy or skip, though skipping it removes your information and your leverage. The municipal side is different: in the City of St. Louis a Certificate of Inspection must be obtained before occupancy is permitted, so declining does not make the requirement go away. Ask the municipality what your options actually are.
At what point do you do a home inspection?
Book the private inspection as soon as you are under contract, inside your inspection period, while you still have room to negotiate. Apply for the city occupancy inspection as soon as you know one is required, because the earliest appointment is 3 business days out and the latest is 15 days from the application day. Those are two separate errands.
How fast can a home inspection be done?
A private inspection is usually a matter of hours on site plus turnaround time for the report, and larger or older properties take longer. The city occupancy inspection is governed by its scheduling window, not by how fast anyone works: no sooner than 3 business days from application, no later than 15 days. Failing an item adds repair time plus a re-inspection.
