What permits do you need to open a contractor or trade in Montgomery County?

There is no single figure, and any site quoting one is rounding away the part that matters. Of the 6 records listed for a contractor or trade in Montgomery County, TX, 2 apply to every business of this type and 4 are conditional. Adding every fee on the page together would overstate what most operators pay, because it would include permits they never need.

3 of the 6 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 Structure Permit: $250–$1,600 per permit, by floor area and floodplain status

Permits for a contractor or trade in Montgomery County, TX come from 4 separate offices: Montgomery County Fire Marshal, Montgomery County Permitting Department, Texas Secretary of State, Texas Department of Licensing and Regulation. No single office issues them all, which is why an opening means filing in several places rather than one.

$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.

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.

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.

Texas licenses no general contractor - there is no statewide builder licence. Individual trades are licensed instead: electrical, plumbing and HVAC, each under its own programme. The $110 is the application fee. Published renewal figures conflict between $110 and $165 depending on licence subtype, so no renewal amount is recorded until a reviewer confirms which applies.

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.
