Start With Your Rapid City Property
On a sloped property, watch runoff near foundations from a safe location after rain. Indoors, compare lower-wall damage with roof and plumbing stains. Ask for a repair scope that addresses the entry point and checks wet materials before enclosure.
Rapid City Code Enforcement
Ordinance officers respond to complaints and inspect properties for violations. The office attempts contact with the owner or tenant and uses the city’s enforcement process when necessary.
Before you contact them:Provide the city address, description of the damaged building component and dates it became wet. Ask whether the office handles the interior condition or needs to refer it to building inspection.

State Laws and Rights
Check South Dakota notice requirements and the coverage of your tenancy before using a rent remedy or ending a lease. The local reporting contact above can address only the issues within its stated scope.
South Dakota mold law snapshot
South Dakota does not have a mold-specific statute, but habitability rules still apply.
Under SDCL Section 43-32-8, landlords must keep rental premises in reasonable repair and fit for human habitation, including the maintenance of all electrical, plumbing, and heating systems. This requirement applies except for damage caused by the tenant's fault. The warranty of habitability cannot be waived or modified by the parties to the rental agreement - this "implied" requirement applies whether or not the lease agreement specifically says so and even if the lease tries to waive the obligation. While mold is not specifically mentioned, conditions that promote mold growth (such as plumbing leaks, inadequate ventilation, or water intrusion) would violate these habitability standards.

Repair Notices and Rent Decisions
Start with these South Dakota rules, then check the local regulations section and your property's coverage. A statutory notice period is not always a deadline for finishing every repair. Keep proof of notice and get local legal advice before changing rent payments or ending a lease.
How long does a Rapid City landlord have to fix mold?
No universal mold-specific repair deadline was confirmed for South Dakota in the sources reviewed for this guide. Treat timing as notice-and-condition specific: document the mold and moisture source in writing, use the cited habitability or repair source, and get local code enforcement or legal aid advice before treating any deadline as fixed.
Can Rapid City tenants withhold rent for mold?
South Dakota allows rent withholding in limited circumstances. If the costs of necessary repairs to maintain habitability exceed one month's rent, the tenant may withhold rent and deposit it in a separate bank or savings account maintained for the purpose of making repairs. The tenant must FIRST give written notice to the landlord stating the specific reason for withholding the rent and then provide written evidence of the deposit. The repairs must be necessary to maintain habitability of the premises, such as plumbing, heating, security, electricity, etc. The money in this account shall be given to the landlord once repairs are made, or it shall accumulate until there are enough funds for the tenant to pay for repairs.
Does mold in Rapid City require relocation?
Unclear as a standalone statewide mold relocation benefit in the sources reviewed for this guide. If mold or remediation makes the unit unsafe or unusable, South Dakota tenants should look to the cited habitability, essential-services, condemnation, disaster, or lease-termination rules and ask legal aid whether rent abatement, substitute housing, temporary vacancy, or termination applies.
Does mold have to be disclosed in Rapid City?
South Dakota does not have a comprehensive statewide mold disclosure requirement for rentals. However, SDCL Section 43-32-30 requires landlords to disclose to any actual or potential tenants if they have knowledge of the existence of any prior manufacturing of methamphetamines at the rental property. For real estate sales, South Dakota requires sellers to provide a disclosure form that includes known hazardous conditions such as radon, mold, methane gas, lead paint, asbestos, and toxic materials. Landlords must also comply with federal lead-based paint disclosure requirements under Title X, Section 1018 for properties built before 1978.
