How much does it actually cost to permit a retail store in Montgomery County?
There is no single figure, and any site quoting one is rounding away the part that matters. Of the 9 records listed for a retail store in Montgomery County, TX, 4 apply to every business of this type and 5 are conditional. Adding every fee on the page together would overstate what most operators pay, because it would include permits they never need.
Of the 4 that always apply, 1 carry a flat fee, coming to $0.00. That is a floor, not a total. 6 of the 9 are charged as a range or a formula set by the issuing agency, and 0 have no fee published at all. The ones that vary:
Fire Code Permit: $500 up to 5,000 sq ft, plus $100 for each additional 1,000 sq ft to 50,000 sq ft, plus $150 for each additional 1,000 sq ft above 50,001 sq ft
Floodplain Development Permit: $0–$1,600 per permit, by scope
Commercial On-Site Sewage Facility Permit: $210–$560 per permit, by scope and floodplain status
Temporary Event and Farmers Market Food Permit: $52–$800 per event or per year, by type
Commercial Structure Permit: $250–$1,600 per permit, by floor area and floodplain status
Retail Food Establishment Permit: $250–$500 per year, banded by gross annual food sales
Which offices issue these permits in Montgomery County?
Permits for a retail store in Montgomery County, TX come from 5 separate offices: Montgomery County Fire Marshal, Montgomery County Permitting Department, Montgomery County Environmental Health Services, Texas Secretary of State, Texas Comptroller of Public Accounts. No single office issues them all, which is why an opening means filing in several places rather than one.
Is anything about these requirements changing?
$500 covers the first 5,000 square feet, then $100 for every further 1,000 to 50,000, and $150 per 1,000 beyond that — so the rate goes UP with size rather than down, which is the opposite of every city building schedule in this dataset. A 20,000 square foot building is $2,000 in fire fees alone, on top of the $1,500 structure permit. Budget the two together: for a mid-size commercial building in unincorporated Montgomery County the fire charge is the larger of the pair.
A floodplain determination itself is free, which makes it the first thing to ask for on any site near a watercourse — it settles whether the rest applies. If it does, the premium runs through everything: $300 rather than $250 for non-structure work, and $600 to $1,600 rather than $500 to $1,500 for a new commercial structure. Non-compliance is $200 per incident. Montgomery County took severe flooding in 2016 and 2017, which is the context for a schedule that prices floodplain work separately at every line.
A new commercial system is $400 plus the $10 state-mandated septic fee, rising to $550 plus $10 in the floodplain; an add-on to an existing system is $200 plus $10, or $335 plus $10 in the floodplain. Reinspection is $150 and non-compliance $200 per incident. This is the permit that catches restaurants and childcare centres opening outside a city sewer district, and it is a real constraint on siting rather than a formality — a subdivision review is $340 on top.
$52 for a single event of up to 14 days and $200 for a multiple-event permit covering a year. A farmers market is $100. The two lines worth knowing are the mass gathering fees: $400 under 5,000 people and $800 above, which are charged to the organiser and are the largest single food-side figures on the schedule.
Banded on floor area: a new structure under 5,000 square feet is $500, then $750 to 9,999, $1,000 to 14,999 and $1,500 to 20,000. Inside the floodplain the same bands cost $600, $850, $1,100 and $1,600 — about 20 per cent more, and the schedule stops at 20,000 square feet, so anything larger needs a conversation rather than a lookup. Non-structure work such as demolition, a driveway or disturbed area is $250, or $300 in the floodplain. Two provisions to watch: non-compliance is $200 per violation, and letting a permit lapse costs half the original fee to recertify. This applies in the UNINCORPORATED county; inside a city, the city permits.
$250 low volume, $375 mid volume and $500 high volume — the cheapest banded schedule of any jurisdiction held here, and well under the $773 that Senate Bill 1008 would permit at the top. Amending an existing permit rather than taking a new one is markedly cheaper: $100 low, $150 mid, $200 high. An initial inspection is $150 and a requested inspection or reinspection $150. The late fee is $100.
Required to form an LLC or corporation, not to trade as a sole proprietor. Texas has no statewide general business licence, so for many businesses this filing plus a sales and use tax permit is the entire state-level obligation.
Only needed if you trade under a name different from the one on your formation filing. The certificate is effective for a term not exceeding ten years from the date of filing and does not roll over by itself — it must be actively renewed, and a new certificate can be filed within six months of the original expiring. The $25 is the Secretary of State fee; sole proprietors and general partnerships file with the county clerk instead, at county rates.
There is no fee for this permit — the Comptroller says so directly, which is worth stating because a blank fee reads as though nobody knows. It does not expire on a date, but it is not permanent either: it is valid only while you are actively engaged in business as a seller, and the Comptroller's office may cancel it on finding that you are not. Filing obligations keep it alive, so a return must be filed for every period even when there were no taxable sales or purchases to report. Apply through Comptroller eSystems and allow two to three weeks.
