Finished Basements
Basement is generally a room or number of rooms in a building, completely or partly below the level of the ground. Design is a sketch or drawing or plan using which something – for example basement – may be made.
When most people think of an addition to their home, they think about adding on to the existing structure. What many seem to forget is that their "addition," already 30% completed, is literally right under their noses – in the basement.
Professionally finished basements are a plus whereas unprofessionally finished basements are a minus.
You must obtain permits for finishing a basement. Listed below are the types of permits required, depending on the complexity of the project. Apply for your permits at the Permit Application Center .
- Building permit for construction of architectural and structural elements.
- Electrical permit for all electrical installations.
- Plumbing permit for installations of plumbing and gas piping systems.
- Mechanical permit is not required to install ductwork in a finished basement.
Covenants and Deed Restrictions are regulations set forth by many homeowners or civic associations. Your finished basement will comply with the standard Code (USBC) for residential construction.
There are two options for a plan submission; the requirements for each are listed below. When submitting plans, two complete sets are required for review.
A comprehensive set of construction plans must meet the requirements or show the items listed below.

In the case of an egress window, show the height of the sill above the finished floor and window opening dimensions.

OBTAINING A PERMIT
PERMIT PROCESS
Bring the construction documents described herein to the Permit Application Center where your permit process will begin. Here you will complete a building permit application. Permit technicians will direct you to the appropriate agencies necessary for permit approval. The applicable departments for a finished basement are:
- Zoning reviews finished basements for wet bars and second kitchens.
- Health Department reviews finished basements that are adding basement bedrooms and are served by a private sewer or well.
- Building Plan Review will review for compliance to the applicable building codes.
The building permit is issued when all required approvals have been obtained and applicable fees have been paid. Once your permits are issued, you must post a copy on the job site until the project has received final approval. Most finished basements are eligible for the Walk-Thru program, which allows you in most cases to apply for and obtain your permit in the same day.
Electrical and plumbing permits are issued after the building permit is approved, but may be processed at the same time. Plans submittals are not required.
- A copy of the approved permit and plans, must be on the job site and must be available to the inspector during each inspection.
- All close-in and final inspections for building, electrical and plumbing are required to be conducted simultaneously. The inspector may hold the requests until all trades are ready to be inspected.
In short, professionally finished basements are a plus. Unprofessionally finished basements are a minus!
