Barndominium Builders in Denham Springs, LA

Barndominium builders planning a home in Denham Springs have something many towns never publish: a one-page sheet of the city's construction codes and design criteria. Denham Springs is the largest city in Livingston Parish, a town of 9,286 people in the 2020 census, and the Amite River forms part of its boundary. Inside city limits, that sheet tells us the wind speed, frost depth, termite rating and flood map dates we design around before a single post goes in.

The city's design criteria

The City of Denham Springs adopts the 2021 International Residential Code, including Appendix AQ for tiny houses, as part of the Louisiana State Uniform Construction Code. Its climatic table lists:

• Wind design speed: 123 mph, with no special wind region and no wind-borne debris zone
• Ground snow load: zero
• Frost line depth: 0 inches
• Seismic design category: A
• Termite hazard: very heavy
• Mean annual temperature: 66.9 F

For a steel or post-frame barndominium, the wind number drives the anchor bolts, the column and truss connections, and how the roof panels are fastened. The zero frost depth lets footings stay shallow, but the very heavy termite rating means wood near the ground needs protection and the slab needs proper treatment. That is one reason steel framing appeals to many owners here.

Heating and cooling targets

The same sheet gives Manual J design conditions: an outdoor summer design temperature of 93 F, an outdoor winter design temperature of 31 F, and an indoor summer target of 72 F at 50 percent relative humidity. Those are the numbers an HVAC contractor uses to size equipment for a house in Denham Springs. In a metal building, the insulation package changes the load more than almost anything else, so we settle insulation before anyone sizes a system. An oversized unit in this humidity short-cycles and leaves the house clammy.

Flood maps and the 2016 crest

Denham Springs adopted its Flood Damage Prevention Ordinance on August 24, 2001, and its current Flood Insurance Rate Map took effect April 3, 2012, under community number 220116. Those maps matter more here than almost anywhere. In August 2016, the Amite River crested nearly 5 feet above its previous record at Denham Springs, and a parish official estimated that 75 percent of homes in Livingston Parish were a total loss. If your lot is near the river or one of its low drains, we look at the map panel, the base flood elevation and the 2016 water line together, and talk about how high the finished floor should be. An elevated barndominium, with living space upstairs and a shop or garage below, is one way to handle a low lot.

Inside the city or out in the parish

The city limits cover only about 7.3 square miles, so land just outside town is often part of the search. Livingston Parish covers 703 square miles and grew from 128,026 people in 2010 to 142,282 in 2020. Outside city limits the city's criteria sheet does not apply directly, and your permit, flood review and septic approval run through parish offices instead. Louisiana's parish sanitarians handle onsite sewage permits, and 57 of the state's 64 parishes have their own onsite sewage ordinances, so a rural lot without sewer starts with a call to the parish health unit.

Getting around

Interstate 12 and US 190 cross the city east to west, and LA 16 is the main north-south road in western Livingston Parish. Downtown, the old hardware and drug stores have turned into the Denham Springs Antique Village, a cultural arts district. The town itself dates to 1903, when it was incorporated as a village and named for a local spring and William Denham.
