Building Permits are required within the City of Collinsville, and inspections are mandatory for certain types of work. If you are unsure
whether or not you need a building permit, please call the Building Department to verify. Following are the types of Building Permits
we issue, along with a general description of each:
Limited “U” Permit:
The most common type of building permit is a “Limited” or “U” Permit, which is used for roofing, siding, windows, pools, fences, sheds, decks,
etc., whether residential or commercial. As a guideline, any exterior work valued at more than $500 is eligible for a “U” permit, although
there are exceptions. Several “jobs” can be included on the same permit for the same fee, such as roof, windows, gutters, pool, fence and deck.
The cost is always $50, regardless of the cost of the work. A Limited “U” Permit is valid for one (1) year.

Residential “R” Permit:
All residential work over and above that listed above for the Limited “U” Permit requires an “R” permit, and includes total residential remodels,
basement finishes, total bathroom or kitchen rehabs, room additions, garages, sunrooms, new residential construction and most jobs over $10,000
(with the exception of roofing), and work involving plumbing, drywall, or electric. Some “R” permit projects can be issued at the front counter
while the applicant waits, while others may require plan review by an Inspector prior to issuance, which can take several days. Building plans
maybe required for Residential “R” Permits. The cost of a Residential “R” Permit is based on the total cost of all the work and is valid for
one (1) year.

The demolition of residential and commercial structures, including mobile/modular homes, garages, carports, and sheds, as well as interior commercial

Land Disturbance (Grading) Permits:
Except as exempted by Code, it's unlawful for the owner of a property and/or that owner’s agent to perform land disturbance activities affecting
more than 5,000 square feet of land area or cuts/fills that are greater than 30 cubic yards without first obtaining a land disturbance permit.
If the land disturbance is less than one acre, and if it is determined by the City Engineer that erosion & sediment control plan can be waived,
then a MINOR Land Disturbance Permit can be issued without the need to
prepare and submit sediment and erosion control plans. Typically, individual home construction, outbuildings, additions, and minor residential
improvements and grading operations qualify for MINOR permits. If the land disturbance is one acre or greater, or if the City Engineer cannot
waive the plan submittal requirements, then a MAJOR Land Disturbance Permit will be
required. A MAJOR Land Disturbance Permit will require engineering calculations, design documentation, and sediment and erosion control plans.
Contact the City Engineer at 346-5211 ext. 2211 if you are unsure of the type of permit needed.
