How does Rapid City weather affect pavers?

Rapid City sits at about 3,356 feet in a climate that falls between semi-arid and hot-summer humid continental. The regional airport averages 17.44 inches of precipitation and 48.5 inches of snow a year, with a January mean low of 12.7°F and a July mean high of 86.4°F. Chinook winds can warm the city above 50°F roughly 20 times between December and February, so snow melts and refreezes repeatedly. Third-party summaries of the Rapid City Municipal Code list a frost depth of 42 inches, measured from finished grade to the bottom of a footing. A paver patio is a flexible surface and doesn't sit on frost footings, but pergola posts, covered patios and some walls do, and keeping water out of a patio base is the best defense against frost heave.

Why does clay soil matter?

In 2015, Rapid City homeowners told the City Council about foundation damage from clay soils that expand when wet and contract as they dry, and city officials considered requiring builders to test new home lots for expansive soil. The same movement that cracks foundations lifts and drops patios and walks. For a paver project, that points to a well-compacted crushed rock base, a slope away from the house, and downspouts and sprinklers that keep water off the pavers and their edges.

Do I have to call 811?

Yes. The South Dakota Public Utilities Commission says state law requires notifying South Dakota 811 at least two working days before any excavation begins. The service is free and can be reached by calling 811 or through the online portal at sdonecall.com, and the person digging is responsible for avoiding the marked areas. Your contractor should place the request and keep the marks visible during the work.

Which paver projects need a permit?

PermitMint's summary of the 2021 International Residential Code as used in Pennington County says an uncovered concrete or paver patio at grade is exempt from a building permit. Add a roof, cover or screen enclosure and it becomes an accessory structure that needs a permit. For Rapid City, PermitMint says retaining walls over 4 feet need a building permit with an engineered design, and walls carrying a surcharge need one at any height. The city's Building Services Division takes permit applications through eTRAKiT and also lists a Sidewalk Construction Permit and a Floodplain Development Permit. Spearfish, Sturgis, Custer and the surrounding counties run their own permit offices, so check where you live. A project that doesn't need a permit still has to be built to code.

What are the backyard fire rules?

The Rapid City Fire Department's recreational fire guidelines apply to single-family homes and duplexes. The fire must be in a sound, hard-to-burn container such as a fire ring, fire bowl, chiminea, fire pit or permanent outdoor fireplace. Burn only the fuel the appliance is designed for, such as natural gas, propane or dry cut wood, and never trash or yard waste. Wood can be stacked no larger than 3 feet across and 2 feet high, and the department recommends keeping the fire at least 15 feet from trees, walls, decks and patios. Homes in the Black Hills Fire Protection District need a burn permit.

What about wildfire?

SDSU Extension advises keeping the first 5 feet around a home free of fuel, using gravel, rock mulch or concrete against the siding instead of wood mulch, and storing firewood at least 30 feet from the house. Paver patios and gravel borders fit those recommendations well on wooded Black Hills lots.

How do I check a contractor?

South Dakota has no statewide trade license for paver or landscape contractors. The Department of Revenue requires anyone who contracts to improve real property to hold a contractor's excise tax license, and its guide names laying bricks for a patio, walkway, driveway or retaining wall as excise-taxable work, taxed at 2%. That is a tax license, not a skills credential. The City of Rapid City licenses contractors working inside city limits, posts a current licensed contractors report, and has warned residents that "some will say they have a state license but the state only has an excise tax license."

Questions to ask a contractor

Are you licensed with the City of Rapid City (if I live there), and are you insured?
How deep will the base be, and how will you compact it on clay?
Where will water go, both off the patio and away from the house?
What edge restraint will you use?
Who places the 811 request, and who pulls any permits?
What does your warranty cover, and for how long?

Yes. State law requires notifying South Dakota 811 at least two working days before any excavation. The service is free.

Does a paver patio need a building permit in Rapid City?

An uncovered patio at grade is generally exempt. Covered patios and retaining walls over 4 feet, or with a surcharge, need permits.

Does South Dakota license paver contractors?

Not with a trade license. Contractors need a contractor's excise tax license, which is a tax license. Rapid City licenses contractors within city limits.
