Why Do I Need a Permit?

Permits protect your family and your home.

Permits help you protect your investment and prevent mistakes.

When you take out a permit, you are paying to have a certified inspector come out to make sure work is done safely and to code. You know that  you are protecting your family and also the value of your home.

Construction mistakes can be exasperating, extremely costly and, in some cases, even deadly. Permits empower you to get safe, quality workmanship and avoid big problems down the line.

When selling your home, you are now required by Oregon law to fully disclose all remodeling work and whether or not permits were obtained. With permits and inspections, you can expect a smoother closing process, free of last-minute hassles, inspections and repair work if the home isn't up to code.  

What is the purpose of the permits and codes?

The purpose behind building codes is to give reasonable assurance that a home is safe from structural failure, fire hazards from electrical and heating systems, electrical shock and health risks. The permits provide a permanent record of the work performed and inspections conducted on the project.

Insist on permits!  It doesn't matter whether you do the work as the homeowner or you hire a licensed contractor to do the work - It simply does not pay to cut corners when it comes to protecting the safety of your family or the value of your biggest financial asset, your home.
