Question 1

What actually controls my rehab timeline on a St. Louis fix and flip?

Accepted Answer

The occupancy inspection queue, not the permit counter. The whole City of St. Louis sits inside a Housing Conservation District, so a rental unit anywhere in the city needs an occupancy inspection before it is re-rented, and rentals reinspect every three years or on any change of occupancy (owner-occupied properties are exempt). The city schedules that inspection 3 business days to 15 days out from application, and a failed inspection restarts the clock, so build two to three weeks of inspection lag into your rehab schedule on top of the construction itself. Permit fees and plan-review timelines for the city or St. Louis County were not published as of this research; do not budget a figure you have not confirmed with the city Building Division.

Question 2

How does Missouri's reassessment calendar affect my carrying costs on a St. Louis flip?

Accepted Answer

A 2026 rehab carries at the pre-rehab tax bill through the rest of that year. Missouri reassesses property every odd year, and the next general reassessment date is January 1, 2027, so improvements made in 2026 are not picked up until then. In the City of St. Louis, a residential parcel is taxed on 19% of value at a total rate of $8.1867 per $100 assessed, an effective 1.556% of market value, while a parcel that lands in the commercial subclass instead pays 32% of value at $9.7522 per $100, an effective 3.121% of market value, roughly double. Confirm your parcel's subclass with the city Assessor before you size the holding-period tax line.

Question 3

What insurance risk actually gates a St. Louis flip while the property sits vacant?

Accepted Answer

The vacancy clause, not the tornado, is the everyday risk. Standard commercial property forms suspend theft, vandalism, water-damage and sprinkler-leakage coverage once a building has sat below about 31% occupied use for 60 days, and vacant buildings in St. Louis are a documented target for brick theft, enough that an alderman has floated a city 'brick bank' to slow it. Add the storm risk on top: an EF3 tornado crossed north St. Louis City on May 16, 2025, and Missouri's insurance regulator recorded nearly 9,000 claims with roughly $208 million paid on that single event by mid-2025. Carry a builder's-risk or vacant-structure policy for the hold period, not a standard landlord form.

Question 4

What does it cost to hold a vacant St. Louis property too long during a flip?

Accepted Answer

More than it used to, and the old ceiling is gone. The city charges a $200 semiannual vacant-building registration fee on residential property vacant six months or more in violation of the building code, and any city-ordered demolition, securing or repair work becomes a special tax bill that is both a lien on the property and a personal debt against the owner. Proposition V, a November 2024 city charter amendment, removed the old $500 cap on fines and fees for ordinance violations tied to vacant and non-owner-occupied deteriorated buildings, and under state law the dangerous-building fine ceiling doubles where the owner does not also live in the property. Order a full tax and special-assessment search before you buy a vacant St. Louis building, not just a title commitment.

Question 5

If I buy a St. Louis rehab out of the city's land bank, what deadline comes with it?

Accepted Answer

Twenty-four months to bring it to occupancy standard, under the Prop NS track. The city's Land Reutilization Authority holds roughly 9,000 properties, about 85% vacant lots and 15% vacant buildings, and its Prop NS program sells vacant residential buildings of six units or fewer to the highest bidder who can complete rehab to City of St. Louis occupancy standards within 24 months. Treat that covenant as a financing deadline, not fine print, when you size a flip's timeline and exit around land bank inventory.

Question 6

I'm flipping a house in Florissant. Does the sale itself trigger a municipal inspection?

Accepted Answer

Yes, and it applies to the sale, not just a new tenant. Florissant requires an occupancy inspection on any change of occupancy, including a sale or transfer of ownership, charges a $50 inspection fee, and requires every code violation found to be corrected even if the sale ultimately does not close. Build that inspection into your exit timeline the same way you would a buyer's own contingencies, because it is a municipal requirement that runs independent of your purchase contract.
