Does the Town of Gage, Oklahoma have zoning?

Yes. The Town of Gage's zoning chapter is in force inside the corporate limits81. The town's districts are A-G general agricultural, R-S single-family residential, R-G general residential, C-C, C-A/R, C-G, I-L and I-H3. Land the town annexes is treated as R-S single-family residential until it is reclassified1.

The town's code is current through an ordinance passed in 2022, so later changes may exist1. Ask the town which district a specific lot is in before you buy.

What are the lot size, setback and height rules in Gage's R-S district?

In the R-S single-family residential district, the Town of Gage requires a lot of at least 6,000 square feet with at least 50 feet of frontage5. Buildings may cover at most 30% of the lot and stand at most 35 feet tall910.

The front yard setback is 25 feet, interior side yards are 5 feet (10 feet on the street side of a corner lot), and the rear yard is 20% of the lot depth11. Other districts have their own numbers, which we have not confirmed.

Can you put a mobile home or manufactured home in Gage?

Inside the R-S district, the Town of Gage allows a mobile home only when the board of adjustment grants it after a public hearing6. The site must be at least 5,000 square feet, the lot at least 50 feet wide and 100 feet deep, and the home must have at least 750 square feet of living space6.

Front yards must be at least 20 feet and side and rear yards at least 10 feet, and the home needs an enclosed foundation, a connection to all public utilities, and signed consent from all property owners within 300 feet6. Oklahoma treats an occupied manufactured home as a permanent installation12.

Do you need a building permit in the Town of Gage?

We could not confirm whether the Town of Gage requires a building permit, what code it enforces, or what it charges. The town's building regulations chapter is listed in its code, and the town clerk can say what applies to your lot.

Two things are known. Oklahoma's statewide codes are minimum standards that a municipality may exceed4. And the town's zoning chapter includes a zoning clearance permit, though we have not read its terms, so ask the town whether it applies before you start work.

How do septic permits work inside the Town of Gage?

Oklahoma DEQ issues septic permits for new or modified on-site sewage systems anywhere in Ellis County, including incorporated towns unless a stricter local rule applies13. An Authorization to Construct must be purchased and issued by DEQ before installation14.

The Report for On-Site Sewage must be reviewed by DEQ before the Authorization to Construct is issued14. Inspection and approval, by DEQ or a certified installer, must happen before the system goes into use15. Whether Gage has a public sewer line serving your lot is something to confirm with the town.

What stays with Ellis County and the state?

Septic permits, groundwater rules and floodplain questions are not decided by the town's zoning chapter. Domestic wells for household use do not need an Oklahoma water permit7. Floodplain rules are enforced by local participating communities, so ask the town whether your lot is in a flood hazard area16.

The rules for unincorporated land outside town limits differ; see the Ellis County page for those.

What should you check before you buy land in Gage?

Confirm the zoning district of the lot with the town, and whether the lot meets the R-S minimums if it is residential5. Ask whether the town requires a building permit and a zoning clearance permit.

For septic, expect a soil evaluation and a DEQ Authorization to Construct14. Ellis County farmland is valued at about $1,200 per acre17, and the county's effective property tax rate is 0.7%18.

Watch-outs

  • We could not confirm the Town of Gage's building permit, inspection or fee rules, so ask the town clerk before you start work, because Oklahoma lets municipalities exceed the state minimum codes4.
  • Mobile homes in the R-S district need board of adjustment approval after a public hearing, with signed consent from owners within 300 feet6.
  • We could not confirm what Gage's code says about RVs, tiny homes or accessory dwellings, so ask the town before you move one onto a lot, since the town sets use rules district by district3.
