Why get a building permit for my rehab project?
​There are many important reasons to obtain a building permit and get the required inspections for your rehab project:

#1 It's the Law

​Permits are required by local city ordinances and if you are found to be working without a permit it can result in hefty fines, demolition and removal of the improvements and even jail time!

#2 Improves Project Safety

​Besides the law, the most import reason to get a building code is because it protects families from potential risks such as structural failure, fire hazards and electrical shock.  

​The building permit allows mandatory inspections from the local code official who ensures the project is meeting local code guidelines and safety standards.  The inspector coupled with an experienced and competent contractor can provide a system of checks and balances resulting in an overall safer project.

#3 Makes Selling the Property Easier

​When selling a property, a rehabber is often required to list any improvements made and declare if permits/inspections were obtained to perform the work.

If the property is being financed through a financial institution, they will often require proof of a final inspection.  If the inspector finds that the modifications were made without a permit, you may be required to tear down the addition/improvements or make costly repairs.

Obtaining a permit & local inspections can give your credibility and reassurance with the buyer that the rehab was done correctly and safely.

#4 Helps Protect Property Values & Your Investment

As a rehabber, you and/or your investors are forking out hundreds of thousands of dollars to purchase the property and fund the rehab improvements.

Like with any other investment, it is important to minimize risk and protect yourself from financial loss by using qualified contractors and building-out safe and high-quality improvements.

​If the contractors you are hiring are unqualified to perform the work and their improvements do not meet local building codes or quality standards, (and you get caught) there's a chance you may be required to demolish and tear out all the 'improvements' and start from scratch and potentially face hefty fines!

Potential home buyers and their inspectors can tell if you cut corners or if the craftsmanship is shoddy, which will reduce your credibility with your buyers, effectively decreasing the # offers you receive & the value you can derive from the property.
