Home Addition FAQs
Here are a few frequently asked questions related to home addition construction:
You can find home addition contractors in Longmont by 1) asking a neighbor for a referral, 2) searching for “home addition contractors” in your favorite search engine, 3) using a traditional paper directory resource (yellow pages), 4) looking for ads on your local TV station, 5) using an online matching service.
In general, hiring an architect or designer to prepare construction documents is likely necessary. The structural elements of the building will need to be designed and stamped by a licensed structural engineer. If you need to do foundation work, you may also need a civil engineer to make sure the site is properly graded. You can ask your builder if they could assist you with the design process (ie: do the project using a design/build approach) or whether they would prefer you hire an architect separately to prepare drawings. Either way, the final design documents will then need to be submitted to your local permit office for approval.
Building a home or an addition requires a contractor’s license in most localities. However, many localities provide exemptions when property owners choose to serve as the general contractor for a property that they own. You will need to research your local laws. For instance, here is a link to a Florida statute addressing owner-builder exemptions. There are pros and cons relating to serving as an owner-builder. For instance, you will assume many of the responsibilities and liabilities associated with the project.
It is highly likely that you will need a building permit to build a home addition. Discuss the permit process with the contractors you are considering for the project. A seasoned and reputable contractor should be comfortable and willing to help guide you through the process or willing to handle the task as part of their contract.
