Does Oak Point, Texas have zoning?

Yes. The City of Oak Point divides the city into zoning districts under its own zoning ordinance: A, RE-5, RE-3, R1, R2, R3x, R4x, MHRx, NC, CC and PD1. Single-family lot sizes depend on the district: RE-5 requires 5 acres, RE-3 requires 3 acres, R1 requires 1 acre, R2 requires 22,000 sq ft, and the R3x, R4x and MHRx districts run from 15,000 down to 10,000 and 12,000 sq ft4. Check which district a specific parcel sits in before you assume a lot size, because the same street can hold different districts.

In the residential districts the main building is limited to two and one-half stories and 35 feet8.

How big does a house have to be in Oak Point?

Oak Point sets a minimum dwelling size by district. A, RE-5, RE-3 and R1 require at least 2,500 sq ft, R2 requires 2,000 sq ft, R3x requires 1,500 sq ft, and R4x and MHRx require 1,250 sq ft5. Because the smallest minimum in the districts we reviewed is 1,250 sq ft, a typical tiny home would fall below the city's minimum dwelling size; we found no tiny-home-specific rule, so ask the city before planning one5.

Lot coverage is capped at 20% in A, RE-5 and RE-3 and at 30% in the other single-family districts9. Setbacks vary by district: R1 asks for 45 feet front, 20 feet side and 40 feet rear, while RE-5 asks for 60 feet front, 40 feet side and 100 feet rear10.

Do you need a building permit in Oak Point, and who issues it?

Inside Oak Point city limits, building permits, plan review and inspections come from the city's Building Permits and Inspections Division, not from Denton County3. The city says it enforces the codes it has adopted, including heating and cooling, electrical, plumbing and building3. The page we checked lists the 2021 editions of the International Building, Residential, Plumbing, Mechanical and Fuel Gas codes3.

We could not confirm the city's step-by-step permit process, its fee amounts or any owner-builder rules. Call city hall at the number below for those. The city publishes a fee schedule in its code of ordinances11, and splitting a larger tract into lots falls under the city's subdivision regulations12.

How do septic permits work in Oak Point?

We could not confirm who issues septic permits for addresses inside Oak Point city limits. Denton County Public Health's Environmental Health Division administers the county's septic (OSSF) order throughout the unincorporated portions of Denton County, and the county notes that incorporated municipalities may have separate permitting authorities7.

Texas requires a permit and approved plan to build, alter, repair or extend a septic system13. Call the Environmental Health Division and city hall and ask which one handles your address before you rely on septic. County-level soil data rates only about 10.3% of Denton County soils as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system14.

Can you live in an RV or manufactured home in Oak Point?

Manufactured homes appear to be limited in Oak Point. HUD-code manufactured homes are placed in a dedicated MHRx district, and we could not confirm that other districts allow them6. MHRx lots need at least 12,000 sq ft4.

We could not confirm whether Oak Point allows living in an RV on a lot, or temporary camping, because the zoning ordinance text we reviewed did not address them. Ask the city's Building Permits and Inspections Division before you buy land with the plan of parking an RV on it3.

Building a home in Oak Point: the steps, in order

  1. Find the parcel's zoning district with the city and confirm the minimum lot size, home size and setbacks for that district2.
  2. Apply for building permits through the city's Building Permits and Inspections Division, which handles plan review and inspections3.
  3. Ask the city and Denton County Environmental Health who permits septic at your address, then apply with that office7.
  4. If the driveway meets a state highway, apply to the local TxDOT district office on Form 105815.
  5. If you are splitting land, check the city's subdivision regulations first12.

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

Denton County's own Development Permit and building rules apply to unincorporated land, not to parcels inside Oak Point16. For land outside the city limits, see the Denton County page.

County-level figures: Denton County's effective property tax rate is 1.7%17. Zoning, minimum home size and lot rules are the city's, so read the district table for your parcel before you make an offer2.

Watch-outs

  • Oak Point's building codes, building permit steps and fee amounts were not confirmed here; call the Building Permits and Inspections Division before you budget3.
  • Septic authority for addresses inside Oak Point city limits is unconfirmed; the county's septic office covers the unincorporated portions of Denton County7.
  • Manufactured homes are tied to the MHRx district, so a lot in another district may not accept one6.
