Does Paris, Texas have zoning, and what does it mean for RVs and tiny homes?

Yes. The City of Paris Planning Office maintains the Paris zoning ordinance and the official zoning map for land inside the city². The published districts include Agricultural, three single-family districts (SF-1, SF-2, SF-3), two-family, four-family, multiple-family, commercial, industrial, planned-development, institutional and historic overlay districts⁸. Minimum lot sizes, setbacks and home sizes depend on the district, so look up your parcel on the zoning map before you buy.

We could not confirm whether Paris allows living in an RV, a tiny home, a manufactured home or an accessory dwelling in any given district. Call the Planning Office with your parcel address and ask for the use table for that district⁹.

Do you need a building permit in Paris, TX, and who issues it?

Yes. Paris requires a building permit to erect, construct, enlarge, alter, repair, replace or remove any structure or building, and the requirement covers storage sheds, garages, carports and fences¹. The City of Paris Building Department issues them¹⁰. The city has adopted the 2024 International Building Code and International Residential Code and the 2023 National Electrical Code⁴.

The permit fee is based on the total cost of labor and materials⁷. The city says a permit can take up to 14 business days to issue when no plan changes are needed, and you can apply online or pick up an application at the City Hall Annex, 150 SE 1st St.¹¹

What inspections does Paris require?

Every development project in Paris must have proper zoning for its use, sit on a platted lot, hold a valid site permit or building permit, be inspected during construction, and receive a certificate of occupancy⁵. Plan for the certificate of occupancy before you move in or connect permanent use⁶.

How do septic permits work inside Paris, Texas?

Texas requires a permit to construct, install, alter, extend or repair an on-site sewage facility (OSSF), and local programs can be stricter than the state minimums³. We could not confirm which agency issues OSSF permits for property inside Paris city limits, or whether a lot inside the city must connect to city sewer. Ask the Paris-Lamar County Health District, then the Building Department, before you buy a lot without sewer service¹².

The state's exemption for single-family homes on tracts of at least 10 acres is written for rural land and has conditions about site evaluation and setbacks; whether it helps a parcel inside Paris is unconfirmed³.

Building a home in Paris, TX: the steps, in order

1. Check the parcel's zoning district on the official zoning map, and confirm the lot is platted⁵.
2. If you are dividing land, remember Paris requires a plat when land inside the city or its extraterritorial jurisdiction is split into two or more parts¹³.
3. Ask the Health District and the Building Department how sewage will be handled¹².
4. Apply for the building permit with the Building Department, online or at the City Hall Annex¹¹.
5. Build to the adopted codes and call for inspections during construction⁴.
6. Receive a certificate of occupancy before use⁶.

What stays with Lamar County, and what to check before you buy

City rules apply only inside Paris. Land outside city limits in Lamar County is handled differently; see the Lamar County page. Outside the city, Lamar County has adopted no county zoning ordinance¹⁴. Plat rules also reach the city's extraterritorial jurisdiction¹³, so check which side of the line a parcel is on.

A new driveway onto a state highway needs a TxDOT driveway permit¹⁵. Private wells are registered only if the property falls inside a groundwater conservation district, and we could not confirm a well rule inside Paris¹⁶. Lamar County's effective property tax rate is about 1%¹⁷, and USDA rates about 7% of county soils as not limited for a conventional septic drain field, so most sites without sewer need a site evaluation¹⁸.

Watch-outs

• Owner-builder rules, RV and tiny-home occupancy, and the sewer-connection requirement inside Paris are unconfirmed; ask the Planning Office and Building Department before you buy⁹.
• Paris permits fences and sheds as well as houses, so even small projects need a building permit¹.
• Do not apply Lamar County's unincorporated-land answers to a lot inside Paris, or Paris rules to a lot outside city limits².

A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
