Fairview Heights incorporated in October 1969 after developing out of farmland, per the city's own history page; French Village, an unincorporated community, sits immediately to its west.
Fairview Heights
Median home age is about 41 years. The city incorporated in 1969 on what had been farmland, so its housing stock is almost entirely post-1969 suburban construction.
What that vintage turns up
First-generation vinyl replacements went in across this whole period and they are now hitting both of the ages that matter at once: the frames are inside the twenty-to-forty-year band and the sealed glass units are well past the eight-to-twenty-year band. That combination produces the most common call we get on houses this age — fogged glass in a frame that is still perfectly sound. The honest first answer there is replacing the glass unit, not the window.
Hardboard and wood-composite lap siding from this era is the one with the paperwork. Masonite's hardboard covered product installed between 1980 and 1998 and reached roughly four million homeowners; Louisiana-Pacific's Inner-Seal siding had its own national settlement in the mid-1990s. Both claim programmes closed years ago, so the relevance now is diagnostic rather than financial: swelling, delamination and mushrooming along the bottom edges of the boards on a house of this age is a known product history, not necessarily the owner having neglected it.
The one to watch on a house of this age
Synthetic stucco applied before about 1997 is the high-risk cohort. Roughly ninety-five per cent of American applications were the face-sealed kind, which has no way to drain what gets past it, and the failures traced back overwhelmingly to flashing that was left out. Drainable systems are a different animal and are not the problem.
Lead paint. No, for anything built after 1978 — but confirm the build year before assuming it. 55.3% of the homes in St. Clair County were built before 1980, and on anything pre-1978 the EPA renovation rule applies to both of these trades. Window replacement is never exempt from it, at any size — a single window triggers it. A whole-house re-side clears the twenty square foot exterior threshold on the first wall. What the rule actually requires of a contractor.
Next door
Fairview Heights shares a boundary with French Village. Where we have a page for a neighbour it is linked; where we do not, the rules there are still different from the rules here.
The rules in Fairview Heights
Siding replacement Permit required
Rests on the department's published general rule, not a siding-specific line. The Building Permits and Inspections page states: 'Building permits shall be obtained prior to making improvements or alterations to a property,' and that the department 'handles the issuance of all building permits and occupancy permits for residential and commercial properties, as well as signage permits.' Siding is not named. The only published exemption found is for fencing ('no permit is required for fencing,' though setback rules still apply); storage buildings of 200 square feet or more and swimming pools over 24 inches deep are named as requiring permits. Re-siding is not listed among exempt work.
Window replacement, same opening Permit required Enlarging or cutting an opening Permit required
Same published basis: 'Building permits shall be obtained prior to making improvements or alterations to a property.' The city publishes no window-specific rule and no distinction between same-opening replacement and a new or enlarged opening.
Illinois sets this, not Fairview Heights — and we are not going to print a number we have not read
This is set in Springfield, not here. The Illinois Energy Conservation Code is adopted statewide by the Capital Development Board, and under the Energy Efficient Building Act no unit of local government — home rule or not — may regulate residential energy standards either more or less strictly than the state does. The Board adopted the 2024 edition, in force since 30 November 2025. It reaches alteration, renovation and repair work for which the municipality or county requires a building permit, limited to the part of the house being modified, and there is no Illinois exemption for replacement windows as such.
The unamended 2024 code figure for this climate zone is U-0.28. But Illinois publishes its own amendments to that code, it has amended that very table before, and we have not been able to open the current amendment document. So we are not going to state U-0.28 as the number enforced here. Buy to the ENERGY STAR figure below and the question does not arise; if you need the exact legal minimum, the Capital Development Board’s energy code office is on 217-685-4079.
For comparison, ENERGY STAR asks for U-0.25 or lower with an SHGC of 0.40 or lower everywhere in this metro, which is stricter than every code edition in force here. And the code only bites when the sash and the glazing are replaced together — replace the glass alone in an existing sash, or add a storm window over the top, and it does not apply.
Contractor registration Not published
No contractor registration, local licence, bond or insurance requirement appears on the Building Permits and Inspections page or the Land Use & Development department page on either of the city's two websites.
Local quirks
Neither publishes adopted code editions, a fee schedule, or contractor requirements. Published exemption of note: 'no permit is required for fencing.' Accessory-structure threshold is 200 square feet (compare Waterloo's 50 sq ft).
