Commercial construction in Idaho moves at a fast pace. General contractors often need to step in when a subcontractor fails to clean a site or fix defective work.
Taking a deduction from the pay of a subcontractor seems like a simple solution. However, many contractors face legal hurdles because they handle back charges incorrectly under state law.
Do not apply residential rules to commercial sites
A common mistake is following the wrong set of laws. Some contractors try to apply the Notice and Opportunity to Repair Act (NORA) to commercial disputes. This law creates a specific process for construction defects. However, Idaho Code limits its application to residential dwellings, like houses or duplexes or residential cooperative units. It generally does not apply to standalone commercial projects such as office buildings or retail spaces.
On a commercial job your prime contract dictates how to handle defects and back charges. If you pause work based on a residential law that does not apply you may fall behind schedule. This could result in a lawsuit for delay damages. An attorney can help you determine which rules govern your specific project.
Avoid using vague documentation for costs
A subcontractor will likely dispute any charge that lacks detail. Many contractors fail to keep precise records during the repair process. To ensure a back charge stands up in court you should gather specific evidence:
- Take photos before the work starts and after it ends.
- Record the exact hours your crew spent on the specific task.
- Keep receipts for any extra materials you purchased.
- Identify the section of the contract the subcontractor breached.
These detailed records help prove the costs were necessary and prevent claims that your charges are arbitrary or padded.
Do not overstate credits and offsets
It is tempting to add high administrative fees to a back charge. However, Idaho Code requires a lien claim to be a statement of demand after deducting all just credits and offsets. Idaho courts take this seriously.
Under Idaho case law a court may invalidate an entire lien if it finds you willfully or fraudulently overstated the amount. This often happens when a contractor adds unauthorized management fees. Accurate accounting ensures your legitimate repair costs remain protected.
Protect Your Commercial Interests
Managing commercial construction projects requires an understanding of the contract documents and Idaho Code. When you withhold funds improperly, a subcontractor may have contractual and statutory remedies.
These disputes can stall your project and lead to expensive litigation. A legal professional can review your contracts to ensure you’re complying with the contract and Idaho law.
