Barndominium Builders in Richland, Washington

Richland's code keeps two zones for owners who want room inside the city: an agricultural district with five-acre lots and a suburban agricultural district built around one-acre homesites with animals and crops. On those parcels a barndominium can share the ground with a pasture and a few animals without leaving the city. Inside the limits, the City's Building Permit and Inspection office permits the house through its online portal, City sewer serves most lots, and drinking water is treated from the Columbia River. Parcels outside the limits belong to Benton County, and Kennewick and Pasco keep their own permit offices. We design and build the whole project: a custom plan that fits the shop bay and living space to the setbacks, site preparation, the permit set and a turnkey build. If you would rather put up the frame yourself, barndominium kits in steel or pole barn homes are the starting point. Share the parcel through the survey and we will check its zone, the sewer and water hookups, and the City's design values before a plan is drawn.

Barndominium Kits and Pole Barn Homes in Richland

A kit suits an owner who wants to raise the shell with their own crew. A pole barn home sets its frame on posts and trusses (the engineering term is post-frame construction) and suits a wide, simple layout with a shop bay under the same roof; a metal building home uses a bolted steel frame. Which one fits your parcel comes down to the zoning, the site and the design values the local building office publishes, covered below.

Building a Barndominium in Richland: Permits, Zoning, Septic and Water

On rural land the zoning, septic and water answers often come before the building answer. Here is who decides each part in Richland, taken from the office or document that publishes it. Rules change, so check them again against your parcel before anything is drawn.

Who issues the building permit City building department

City of Richland Development Services, Building Permit and Inspection

Richland's Building Permit and Inspection office in Development Services regulates the construction, alteration and occupancy of all buildings within the city and calls itself a one-stop shop. Since 3 June 2024 applications go through the City's EnerGov planning and permitting portal, and the office posts residential submittal requirements and handouts on detached garages, retaining walls and floodplain construction. Land outside the limits goes to Benton County.

Who decides the land use Inside an urban growth area

City of Richland Planning Division

Chapter 23.14 of the Richland Municipal Code sets two agricultural zones. The AG district, applied to land the comprehensive plan designates agriculture or urban reserve, has a five-acre minimum lot. The SAG district provides rural-style residential areas with lots large enough for certain animals and farm crops, with a 43,560 square foot minimum lot and 145-foot minimum width and depth.

Sewer or septic Public sewer

City of Richland Wastewater Utility; Benton-Franklin Health District off the sewer

Richland's wastewater treatment plant, built in 1985, serves about 62,220 residents through roughly 316 miles of sewer line kept up by City crews. A lot on that system connects to it. Where no sewer reaches the parcel, an on-site septic permit comes from the Benton-Franklin Health District.

Where the water comes from Public water system

City of Richland Water Utility

The City's Water Utility names the Columbia River as the main source of Richland's drinking water, and it also runs four irrigation systems, at Columbia Point, Horn Rapids, Smart Park and the Heights of Meadow Springs, for landscape water. Land beyond the City system normally relies on a private well, which must show an adequate supply before the permit is issued.

Richland local design criteria
Richland's local design criteria sheet (dated 2 April 2024) sets a 20 psf ground snow load, a 24-inch frost line depth, a 110 mph ultimate design wind speed and Seismic Design Category C for homes under the residential code (D for commercial buildings), and requires ice barrier underlayment. It dates the City's entry into the flood hazard program to 1 March 1984.

Livestock in the SAG zone
In Richland's suburban agricultural (SAG) district the code allows orchards, vineyards, gardens, field crops and pasture, and up to two animal units per acre of fenced gross pasture, for example one horse and one cow, or ten sheep or goats. A fence or shelter must be in place before the animals arrive.

Building on land near Richland

Look up the zone before the price: a standard residential lot in Richland is fine for a house with an attached garage, but a real shop bay, a pole barn or animals point to SAG or AG land, which the City zones for exactly that. Check the flood map for parcels near the rivers, since the City's design sheet points builders to its GIS flood hazard maps, and ask whether the lot is on one of the City irrigation systems for landscaping. Plan footings to the 24-inch frost line and roof framing to the 20 psf snow load. If the parcel you like sits past the city limits, the rural zones, private wells and the county's water mitigation rules on our Benton County page apply instead.

Building in Richland: questions

Start the survey
How much does it cost to build a barndominium in Richland?
It depends on the parcel as much as the building. An acre in the SAG zone may need a longer sewer or water run, fencing for animals and more grading than a city lot, while the size of the shop bay and whether you start from a kit or a turnkey package shift the total most. We quote against the real site. Read our barndominium cost guide for sourced ranges before you set a budget for Richland land.
Do I need a building permit for a barndominium in Richland?
Yes. A barndominium used as a home is permitted like any new house, and inside the city the application goes through Richland's online permitting portal to the Building Permit and Inspection office. Land outside the limits is permitted by Benton County, and Kennewick and Pasco have their own offices. Tell us the parcel through the survey and we will confirm who reviews it.
Where can I build on acreage and keep animals in Richland?
Look for land zoned SAG or AG. The SAG district is meant for homes on one-acre-plus lots with room for horses, cattle, sheep or goats at up to two animal units per acre of fenced pasture, and the AG district requires five acres. Standard residential zones are not the place for a working barn. We can size a custom plan to either zone's setbacks.
