    Do ordinary replacements need Addison permit review?

    Addison's permit page includes replacement windows, doors, roofing and siding among projects requiring review. Before agreeing to a seller repair or ordering materials, describe the exact replacement to the Community Development Department. Keep the issued permit and completed inspection record with the property's improvement history.

    What drawings should accompany an Addison exterior project?

    Addison distinguishes exterior work from interior alterations in its application guidance. Exterior proposals need a current survey or site plan showing the improvement's location and dimensions; interior projects need an appropriate floor plan. Buyers evaluating an addition should obtain these drawings before assuming the advertised expansion is feasible.

    Local research · Seller questions

    How can an Addison seller document that permitted work finished?

    Addison says permitted projects require at least a final inspection, with additional inspections identified in the permit conditions and online portal. A paid contractor invoice alone does not establish that closeout occurred. Ask the Community Development Department to reconcile the permit number, approved scope and recorded inspection result before listing.

    Does Addison register every renovation contractor?

    Addison's guidance says it does not require general contractor registration, but requires the roofing license, the 055 and 058 plumbing licenses and a letter of intent with every online permit application. Verify the documents for the trade actually hired. General registration status should not replace checking qualifications or obtaining the project's required permit.

    Local research · Seller questions

    What sewer clearance belongs in an Addison closing plan?

    Addison's transfer process includes a sewer compliance certificate, with separate scheduling and validity limits on the Village page. Sellers should arrange the inspection early and have the closing team confirm the certificate will remain acceptable through closing. An ordinary home inspection does not substitute for this municipal clearance.

    Local research · Seller questions

    Why can an old Addison permit affect a sale?

    Addison requires a permit release as part of its real-estate transfer procedure. That review checks open permits, outstanding inspection matters and related fees. Before setting a firm closing date, ask the Village to identify unresolved items and obtain the release after the required closeout work is recorded.

    Local research · Buyers & sellers

    Can the Addison buyer's water setup affect the seller's final bill?

    Addison's transfer instructions make buyer water preregistration part of the final-billing sequence. Sellers also arrange a final meter reading and clear the resulting bill before the transfer stamp is issued. Coordinate both parties' submissions with the closing team so the account handoff does not stall the municipal clearance.

    Do Addison condominium transfers follow the same utility inspections?

    Addison's transfer page specifically distinguishes condominiums: it says they do not require the water-account, sewer or sump-pump inspections described for other properties, while the permit release remains applicable. Have the Village confirm the property's condominium classification and the complete transfer package rather than treating that exception as a blanket exemption.

    Who investigates an Addison sewer blockage near a parkway tree?

    Addison's sewer guidance distinguishes root intrusion associated with a Village-owned tree in the area between street and sidewalk. The Village describes correcting blockages attributable to such trees. Report the problem to Public Works and establish the cause before assigning responsibility or promising a buyer that municipal repairs will cover it.

    Local research · Buyer questions

    What should an Addison buyer ask about an existing sewer backup device?

    Addison recommends regular maintenance of an interior backflow device and identifies an overhead sewer as another protective approach. Ask the seller which system is installed, where it is accessible and when it was last serviced. A device's presence alone does not establish its condition or eliminate a property's backup exposure.

    Local research · Buyer questions

    Does a basement sewer smell establish an Addison main-sewer defect?

    Addison explains that water can evaporate from a seldom-used drain trap, allowing sewer odor into a home. Buyers should distinguish that possibility from an actual backup and ask about recurrence and prior service calls. Have the cause evaluated rather than assuming every odor proves a municipal sewer-main problem.

    Local research · Buyer questions

    Which Addison resources help investigate a property's flood exposure?

    Addison links both FEMA flood-map panels and DuPage County mapping with contours and historical imagery. Use the parcel location, drainage features and available property records together when assessing a purchase. The Village also links rain and stream monitoring, which supplies current conditions rather than a guarantee about future flooding.
