Backfill Inspection: Foundation walls complete and braced, all forms stripped, damp-proofing, drain tile and gravel in place, and before backfill. Note: If all foundation walls are no lower than 3'6" below grade and braced properly, no backfill inspection is required.
Rough-In Inspection: When framing, rough plumbing, rough electrical, conduit and boxes (wires do not have to be pulled), rough masonry complete before insulation and dry wall.
Under Slab Plumbing or Wiring Inspection: When piping has been laid and properly supported before backfill.
Concrete Slab Inspection: For basements, when gravel, vapor barrier and wire mesh is in place and before concrete is poured. For garages, when gravel and wire mesh is in place and before concrete is poured.
Septic Field Inspection: When tanks and field tile are complete, before backfill.
Final Inspection: When building is completely finished and rough grading done. For houses, a water sample and spotted survey are required. For all permits a spotted survey is required. Note: Pole buildings require final inspection.
Inspection for Certificate of Occupancy: Issued when all final corrections made. Penalties shall be incurred for occupancy without certificate.
(Ord. 76-6, 5-24-1976)
Swimming Pool Inspection, in order of occurrence:
1. When bottom is ready to be poured and all grounding in place.
2. When deck is ready to be poured and all grounding in place.
3. When all work described in the building permit application is completed.
Satellite Antenna Inspection: When antenna is anchored to the concrete platform and effectively grounded and screening is in place as described in the building permit application.
Final Inspection: When the building, including pole buildings, is completely finished with those items required by the provisions of this Chapter and rough grading done.
(Ord. 89-13, 10-23-1989)
Inspection for Certificate of Occupancy or Completion: A certificate of occupancy or completion shall be issued when all final corrections are made and a spotted survey is received. In addition, for a residence, there is required prior to the issuance of a certificate of occupancy (i) an as-built drawing of the septic system, (ii) a water sample and (iii) a successful test of the Emergency Number Telephone System. Occupancy of any building, including, but not limited to, storage of furniture, equipment or other personal property, or the use of such building, prior to the issuance of a certificate of occupancy or completion, shall be subject to the fines and penalties of Section 4-1-9 of this Title.
(Ord. 03-17, 8-25-2003)
Other Inspections: In addition to the called inspections above, the Building Officer may make or require any other inspections to ascertain compliance with this Code and any other laws enforced by the Building Officer. Work shall not be done on any part of the building or structure beyond the point indicated in each successive inspection without first obtaining the written approval of the Building Officer. Such written approval shall be given only after an inspection has been made at each successive step in the construction as indicated by each of the inspections required above.
3. In addition to Section R-112: A building plan for each model must be filed with the Building Officer incorporating all off-site constructed aspects of the structure as well as its final site assembly down to the foundation. These plans must bear the seal and signature of a registered architect or professional engineer licensed to practice in the State of Illinois.
4. Values for Table No. 2-A shall be as follows: Roof live load = 25 PSF; Roof snow load = 30 PSF; Wind velocity at 30 feet above ground = 30 PSF; Seismic Condition = Zone 1; Subject to damage from weathering - yes, 6" above grade; Subject to damage from frost line depth - yes, 3'6" below grade; Subject to damage from termites - yes, moderate; Subject to damage from decay - yes, moderate.
