#119 of 254 in Texas

Unincorporated Navarro County, Texas requires development permits, while residential building permits also apply in the Richland-Chambers Lakeshore Area1. Qualifying new houses, duplexes and major additions must follow the county's adopted residential code and inspection rules2. Navarro County also requires permits for new, modified and repaired septic systems3.

Do you need a building permit in Navarro County, Texas?

Yes, but the permit type depends on location.

Yes, but the permit type depends on location. Navarro County lists a development permit outside the Richland-Chambers Lake zoning area and a building permit within the lake area1. New single-family houses and duplexes on vacant lots must meet the International Residential Code published as of May 1, 2008; the order also covers additions that increase a residence's square footage or value by more than 50 percent2. Manufactured homes under Texas Occupations Code Chapter 1201 and modular homes under Chapter 1202 are excluded from that construction order2. Inside the Richland-Chambers Lakeshore Area, the residential building-permit application requires ownership evidence, construction plans, a site or survey plan and the fee; separate trade permits may also be required5.

Who is the Navarro County building department, and how do you reach them?

Navarro County Planning & Development is at 601 N. 13th St., Suite 1, Corsicana, TX 75110, phone (903) 875-3311.

Navarro County Planning & Development is at 601 N. 13th St., Suite 1, Corsicana, TX 75110, phone (903) 875-33116. Office hours run Monday through Friday, 8:00 a.m. to 4:30 p.m., closed for lunch from 12 to 16. For covered homes, duplexes and additions, the builder hires an eligible inspector for at least three stages: foundation before concrete, framing and mechanical systems before wall covering, and completion2. A lakeshore residential building needs all required inspection forms before the county issues its certificate of completion5. The county lists a $300 development-permit fee outside the lake zoning area and a lake-area building-permit fee of $0.50 per square foot of structural area1. Starting construction before permits are issued doubles the listed fees1.

Does Navarro County have zoning?

Navarro County's zoning ordinance establishes nine use districts in the Richland-Chambers Lakeshore Area, and Planning & Development maintains the official zoning map.

Navarro County's zoning ordinance establishes nine use districts in the Richland-Chambers Lakeshore Area, and Planning & Development maintains the official zoning map4. For detached houses, the SF-1, SF-2 and SF-3 districts require at least 1,600, 1,200 and 1,000 square feet of floor area, respectively4. Those districts require lots of at least 1 acre, 0.75 acre and 0.5 acre, respectively, while the A district requires 3 acres excluding land below the 315-foot contour4. Maximum building coverage varies by district, including 25 percent in SF-1, 35 percent in SF-2 and 40 percent in SF-34. Each of those single-family districts permits up to 2.5 stories4. Other lake-area dwelling and district schedules differ, and countywide zoning beyond the lakeshore area could not be confirmed; ask Planning & Development for the parcel's mapped district before designing a home.

How do septic permits work in Navarro County?

Navarro County Planning & Development administers OSSF permitting and inspections through its authorized agent and designated representatives.

Navarro County Planning & Development administers OSSF permitting and inspections through its authorized agent and designated representatives1. Every new, modified or repaired septic system in Navarro County requires a permit and must be installed by a licensed installer3. Mailed plans are reviewed within 10 working days, and approval produces an Authorization to Construct3. The owner or installer must arrange inspection when installation is ready, and the system cannot be covered before approval3. Only about 2.7% of Navarro County soils lack severe limits for a conventional drain field, so make septic feasibility an early purchase contingency7.

Can you live in an RV or tiny home on your land in Navarro County?

In the Richland-Chambers Lakeshore Area, an RV cannot be a permanent living facility and no more than one RV may be stored on a lot.

In the Richland-Chambers Lakeshore Area, an RV cannot be a permanent living facility and no more than one RV may be stored on a lot4. Temporary occupancy is limited to 72 hours per permit and five permits in a six-month period; a specific-use permit during permanent-home construction can run 120 days, with discretionary 30-day extensions4. The county lists a $300 temporary RV use permit1. A lakeshore accessory building cannot serve as a residence4. A conventional tiny home must satisfy the applicable lakeshore district's dwelling-size and lot rules4. We could not confirm countywide RV or tiny-home occupancy rules outside that area; give Planning & Development the parcel address and proposed unit before committing.

Building a home in Navarro County: the steps, in order

Ask Planning & Development whether the parcel is in the Richland-Chambers Lakeshore Area and which development or building-permit application applies.

  1. Ask Planning & Development whether the parcel is in the Richland-Chambers Lakeshore Area and which development or building-permit application applies1.
  2. Confirm the mapped district, allowed use, minimum home and lot size, setbacks, coverage and height before commissioning plans4.
  3. Submit the OSSF plans early; mailed plans are reviewed within 10 working days3.
  4. Check flood status; floodplain development in unincorporated Navarro County needs a county permit5.
  5. Submit complete construction and septic materials before work begins3,5.
  6. Arrange foundation, framing/mechanical and completion inspections for covered residential construction2.
  7. For a lakeshore home, submit the inspection forms and obtain the certificate of completion5.

What to check before you buy land in Navarro County

Start with septic feasibility: only about 2.7% of Navarro County soils lack severe limits for a conventional drain field.

Start with septic feasibility: only about 2.7% of Navarro County soils lack severe limits for a conventional drain field7. Verify the survey, flood status and lakeshore zoning district because district-specific lot size, setbacks, coverage and height can change the usable building envelope4. The subdivision manual sets a 1-acre net minimum lot size while directing applicants to use stricter septic requirements when they conflict8. We could not confirm a countywide private-well permit or utility-connection rule, so ask Planning & Development and the serving utility before closing. Navarro County averages about 41.2 inches of precipitation annually and has experienced severe drought in about 16.3% of years7.

Watch-outs

  • Navarro County doubles its listed fees when construction begins before permits are issued6.
  • The owner-builder provision only exempts a primary-residence owner-builder from referral for a notice-related misdemeanor; it does not waive building permits, inspections or code compliance2.
  • In the lakeshore zoning area, an accessory building cannot be used as a residence4.
