Which Montgomery County rules apply to this address?
Use the County jurisdiction guidance to establish unincorporated territory. Conroe, Montgomery and other incorporated municipalities retain their own rules; The Woodlands Township also needs specific boundary/private-rule checks. This guide does not impose a city zoning ordinance on unincorporated land.
When is an unoccupied RV exempt from a development permit?
Article 3(D)(7) of the 2025 regulations covers RVs stored on a property owner’s lot where a residence already exists, provided the RV is unoccupied, not connected to water/sewer, currently registered and capable of highway use. Exemptions must still avoid silt runoff and adverse drainage impacts, and the Administrator can request documentation. A new pad or utility installation needs its own review.
Why does exactly 180 days matter?
Article 5(B)(5) uses fewer than 180 consecutive days and fully licensed/highway-ready for the exemption in Zones A1–30, AH and AE. At 180 days, the short-stay route no longer fits; obtain the referenced permit and manufactured-home elevation/anchoring review. The 2014 document’s alternative “or” wording is superseded. Current manufactured-home standards use two feet above base flood elevation, with floodway placement prohibited.
Does a utility hose or permanent addition change the answer?
The 2025 RV clause defines highway-ready as remaining on wheels/jacks, attached only by quick-disconnect utilities/security devices and without permanent additions. It separately addresses an RV on an unimproved tract beyond 180 days that is regularly used and connected to water/sewer, and warns that electrical service may have additional requirements/time limits. These are not general occupancy approvals.
Does building a parking pad count as development?
Articles 2 and 3(C) define development broadly, including paving, grading, clearing, utilities and equipment/material storage. The current County FAQ says proposed unincorporated development needs a permit unless an actual exemption fits. A stored-RV exemption does not automatically extend to separate site work.
Can I live in or connect the RV after a floodplain check?
A floodplain/development determination addresses its own scope. Sleeping, water/sewer, septic capacity, electrical service and deed restrictions need their own facts. The County Floodplain page specifically prohibits installing a new septic system or repairing/replacing one in the floodway. Use Environmental Health before changing a sewage arrangement.
Is there a countywide curbside RV time allowance?
No general RV street allowance was established by the reviewed development/floodplain rules. Confirm the road owner, signs, public/private status and law-enforcement restrictions separately. A permit exemption for home storage or a general abandoned-vehicle clock should not be used as roadside permission.
Who to contact for your setup
Ask Montgomery County Floodplain Administration about the current exemption and exact site, and Environmental Health about sewage or changed connections. Bring the exact address, vehicle details and intended activity. Read the principal official rules.
Use the Unincorporated Montgomery County parking checker to organize the starting conditions. The checker cannot approve a parcel, a variance or an unverified exception.
