Top Home Addition Questions
1. What is the first step in starting a home addition?
A contractor is the first call most people make when considering a home addition. However, there is very little that can be determined before a full set of plans has been drawn. Engineering calculations, structural details and finish schedules are needed before an accurate estimate can be provided. We do not offer design services in house but we have a great team of professionals who we partner with to help you throughout the process. Once the design details are complete and ready to submit for permitting, FIVE40 and our vendors can provide detailed, accurate estimates.
2. How does the home addition permit process work?
The process to obtain a building permit typically takes up to 30 days. During this time the city will review all documents and issue any corrections or changes they want, this is commonly referred to as “red lines.” If any changes are needed, our architects and engineers will address these and resubmit the package for review. Once approved, permit fees are paid, and the permit is issued. Some cities offer rebate incentives of permit fees in order to encourage timely completion.
3. Will the house be secure during construction?
We make every effort to secure any jobsite and property during construction. Temporary fencing will be installed around the property as needed and any unsecured openings are boarded up and taped off to restrict unapproved access.

The remodel required to relocate a water heater to the garage, reconfigure my air conditioning ducting in the attic, and new floor tile. They were reliable, showed up every day, and even worked on the weekend to finish the job. After the job was complete we had an issue with a drain (No fault of theirs). I contacted Shannon the owner and he sent over his guy the next day to fix the problem. We haven’t had an issue since. I highly recommend Five40 Remodeling for your remodeling needs.
