Frequently
Asked Questions
Q: When do I need a permit?
A: A building permit is required for all new construction including
buildings, fences, sheds, decks, and anything else that involves an above-ground
structure. No permit is required for a concrete or paver patio or landscaping
where no structural work is involved. However, a permit is required to construct
parking lots and loading facilities.
A building permit is required for existing structures where the work to
be done is regulated by a code. For example, any changes or replacement
of water or gas piping, wiring, heating and central air conditioning systems,
or water heaters require a permit. Work that affects the structure of any
walls, door and window openings, roof elements, etc., as well as replacement
of permanent exterior coverings such as roofing, siding, and window frames
requires a permit.
A permit is not required for work that is not controlled by the building
codes, such as painting and floor coverings, or installing appliances that
are not permanently attached to the wiring or plumbing systems such as washing
machines or room air conditioners.
If you have any questions about whether a permit is required, please call
us. Obtaining a permit will ensure that the work is inspected so that you
have the comfort of knowing it complies with applicable codes. If you decide
to sell your home or building, the buyer will have that comfort as well.
Q: What kind of drawings or plans do I need?
A: Different kinds of construction require different kinds of plans.
Please check the permit information packet for your type of project to determine
what kind of drawings you need and who needs to prepare them.
Drawings must show all the details of the proposed construction the
size of lumber to be used, size of insulation, electric locations, etc.
Drawings should not exceed 24 x 36 inches.
If your project is for nonresidential construction, or if it involves any
form of structural change (residential or nonresidential), the plans must
be sealed by an Illinois registered architect.
Q: How long will it take until my permit is approved?
A: Each permit is unique, and so the length of time needed for proper
review may vary. Generally, residential construction permits take about
7 to 10 working days if the required information has been submitted and
there are no unusual circumstances. Non-residential permits generally require
a more extensive review, and take about 15 to 20 working days after the
required information has been submitted. As with residential permits, unusual
circumstances can lengthen this time.
Q: Can I start any of the construction work before my permit is approved?
A: We advise applicants to wait until the permit has been issued
before starting any construction. If the project involves demolition of
existing interior improvements, we can authorize that part of the project
to proceed. Please contact the Building and Zoning Office to request authorization
to proceed under these circumstances.
Q: Do I have to pay the permit fees when I apply?
A: You are required to pay a review fee when you apply for a permit.
Certain permits also require additional fees to be paid when the permit
is approved and issued; these additional fees must be paid when you pick
up your permit.
Q: How do I determine the zoning of my property?
A: The St. Charles Zoning Map shows the zoning of all property in
the City. Many newer parts of the City have "Planned Unit Development"
zoning, which means that there is a set of zoning regulations written specifically
for that area. The Zoning Ordinance is available under the "Code Book"
section of this web site as Title 17. Zoning maps may be purchased from
the Utility Billing Counter at the Municipal Center, 2 E. Main Street.
If you want to determine your propertys zoning in person or over the
telephone, you may contact the Building and Zoning Division. You will need
to provide us with the correct address of the property so we can give you
an accurate answer. If you do not know the address, but have a parcel number,
contact the Planning Division for assistance.
