Windows and exterior wall due diligence for Michigan IRA property

A window can open smoothly and still leak at the sill. New siding can hide an older wall assembly, patched sheathing, or flashing that was never connected to the drainage path. Fresh caulk may be ordinary maintenance, but it can also make a short inspection look more settled than the building really is. Exterior due diligence should follow the wall as a system rather than grade the visible finish by itself.

A self-directed IRA buyer also needs a realistic way to pay for further inspection, opening a concealed area when appropriate, and completing accepted repairs. The plan cannot rely on the IRA owner replacing trim, sealing windows, buying materials personally, or covering a contractor invoice until the custodian responds. Those details belong in the purchase review while the buyer still has time to define the work and the account process.

Build the exterior record before judging the finish

Ask for permits, final inspection records, contracts, invoices, warranties, product information, photographs taken during prior work, insurance repair records available to the buyer, and maintenance reports. Match each document to a wall, elevation, addition, window group, or doorway. An invoice that says replacement windows may cover the street-facing rooms while leaving older units elsewhere. A siding contract may exclude sheathing, insulation, flashing, or trim.

Put the work in date order. If a leak led to a window replacement, identify the reported location, what was opened, what damage was found, how the opening was rebuilt, and whether anyone checked it afterward. If a facade was resurfaced, ask what remained beneath it. Keep the seller's explanation beside the contractor and permit records rather than blending them into one conclusion.

• Installation dates and scopes for windows, exterior doors, siding, masonry, trim, sealants, balconies, and attached canopies
• Permits, final approvals, contractor information, warranties, transfer requirements, and photographs before concealment
• Leak reports, interior staining, insurance repairs available to the buyer, and follow-up inspections
• Records for additions, enclosed porches, converted openings, storefront systems, and tenant improvements
• Areas that were inaccessible, covered by finishes, blocked by landscaping, or omitted from an earlier inspection

Trace water from the roof edge to the ground

Begin above the wall. Look at roof edges, gutters, scuppers, parapets, porch roofs, awnings, balconies, and any upper surface that can send water toward an opening. Then follow the likely path across siding or masonry, around windows and doors, past penetrations, and down to the grade. A stain below a window may have started at the window, but it may also have traveled from a roof joint, wall penetration, or opening above it.

West Michigan rain, wind, snow, freeze-thaw cycles, and seasonal temperature changes can expose details that look quiet during one visit. Ask what the inspector could observe under the day's conditions and what would require another method. Snow, recent dry weather, height, occupied rooms, screens, storm windows, vegetation, and unsafe access may all limit the view. A dry surface on inspection day is an observation, not a history of the assembly.

Continue the review at the bottom of the wall. Check how cladding ends near grade, pavement, decks, steps, and planted areas. Look for splashback, buried trim, soil or mulch against materials that were not meant to be covered, damaged kickout or edge details, and downspouts that empty beside the building. Coordinate those findings with the roof, drainage, foundation, and moisture reviews instead of creating four unrelated repair lists.

Inspect each window and door as an assembly

The glass and sash are only the parts most people notice. Ask the inspector or qualified window and building-envelope professional to review the frame, sill, head, jambs, exterior trim, sealants, visible flashing details, interior finishes, hardware, locks, screens, and the wall immediately around the opening. For doors, include thresholds, weather seals, hinges, closers, steps, landings, and the way water is directed away from the entrance.

Operate components only when it is safe and the inspection agreement allows it. Record units that bind, do not stay open, will not lock, show failed glass seals, have soft or damaged trim, or leave visible gaps. Note cracked glass, patched frames, missing screens, water marks, swollen finishes, corroded hardware, and daylight where it is not expected. None of those observations identifies the full repair by itself. It tells the specialist where a focused review may be worth the time.

Replacement inserts and full-frame replacements are not the same scope. An insert may leave the existing frame and some surrounding details in place. A full-frame project may expose flashing, sheathing, insulation, and interior or exterior finishes. Ask bidders to state what will remain, what will be opened, and how the new work will connect to the wall. Comparing only the number of windows can hide a major difference in the job.

Read siding and masonry in sections

Divide the exterior by material, orientation, height, and exposure. Vinyl, wood, fiber-cement products, metal panels, stucco-like systems, brick veneer, structural masonry, and mixed storefront assemblies do not age or shed water in the same way. A repair method suitable for one section may be wrong for the wall next to it. Ask the professional to identify the observed material and explain any uncertainty rather than assigning one label to the whole building.

Look closely at transitions: siding to masonry, an addition to the original building, a deck ledger, an exterior stair, a utility box, a hose connection, a light, a sign, a vent, or piping through the wall. Open joints, displaced materials, bulging, cracking, rust, rot, efflorescence, staining, and repeated sealant patches deserve context. The reviewer should distinguish movement or deterioration from ordinary surface variation and should say when a mason, carpenter, engineer, or envelope consultant needs to examine it.

Masonry deserves more than a count of cracked joints. Ask about the condition of mortar, units, lintels, sills, shelf angles when present, control or expansion joints, weep locations, coatings, and attachments. A painted wall may limit what can be seen. A repair that replaces mortar but ignores a corroding steel component or ongoing movement may improve appearance without addressing the cause.

Separate air leakage, condensation, and water entry

A draft near a window does not automatically call for a new window. Air can move through the sash, frame, rough opening, wall penetrations, baseboard, or another nearby path. Condensation on glass can relate to surface temperature, indoor humidity, ventilation, weather, window performance, and how the room is used. Water staining can have a third cause. Ask the appropriate professional to identify the likely mechanism before one symptom becomes a replacement order for the whole property.

When an energy assessment, infrared scan, blower-door test, moisture measurement, or targeted opening is proposed, ask what decision the test will answer and what conditions it requires. One image or reading should not be treated as a building-wide verdict. The report should record the date, weather, equipment, areas tested, limitations, and how the result connects to the recommended work.

Be careful with repair claims based only on future utility savings. A better window or tighter wall may change comfort and energy use, but savings depend on the building, installation, equipment, weather, rates, and operation. Get the property-specific scope and let the buyer's qualified professionals evaluate cost and performance. Do not use an estimated savings figure to erase a known capital expense from the IRA budget.

Use the right inspection scope for the building

A general property inspection may identify visible concerns from accessible areas. It may not include high elevations, concealed flashing, destructive access, facade engineering, laboratory testing, water testing, or removal of finishes. Ask what methods the inspector will use and what falls outside the agreement. A two-story rental house, a brick commercial building, and a mixed-use property with storefront glazing may need different specialists and access equipment.

If the review depends on a ladder, lift, drone, camera pole, interior opening, or controlled water test, settle permission, safety, restoration, tenant access, and cost before the visit. The seller and property manager should approve access through the contract process. The specialist should define the method. A buyer should not improvise an invasive test or create a new leak to learn whether an old one exists.

Keep inaccessible areas on the issue list. Finished basements, built-in cabinets, tenant belongings, sealed storefront panels, dense vegetation, and upper walls can conceal the exact part of the assembly that matters. The buyer may decide to obtain more access, carry a documented contingency, change the offer, or decline the property. Missing information should not quietly become a clean finding.

Verify permits with the enforcing agency

Michigan LARA's Building Permit Information page says building-code enforcement may be handled by the state, a county, or a local unit of government and directs applicants to the Statewide Jurisdiction List. The correct office can differ among nearby West Michigan addresses. Ask the enforcing agency for permits and final approvals tied to window enlargement, altered openings, wall reconstruction, structural lintels, balconies, facade work, and the proposed repair scope.

LARA's current Code Books page lists the 2021 Michigan Building Code as effective April 9, 2025, while residential requirements are contained in the Michigan Residential Code; the page lists the 2015 Michigan Residential Code as the current residential code. Those statewide references do not decide how an existing condition or planned project will be treated at one address. Ask the enforcing agency and the buyer's design and legal professionals which code, permit, review, and inspection requirements apply to the building and work.

A final approval is useful evidence for the permitted scope at a point in time. It does not establish the condition of every window or wall today, and it does not prove that later work was included. If the building and permit history disagree, keep both facts visible while the buyer's attorney, inspector, and appropriate building professionals decide what further review is needed.

Build a repair scope that includes what surrounds the wall

Ask contractors to price the same written findings. The scope should identify each elevation and opening, removal limits, temporary protection, flashing and water-management details, sheathing or framing allowances, insulation and air-sealing work, interior and exterior finishes, permits, access equipment, cleanup, and closeout records. It should also say how concealed damage will be documented and approved before a change order proceeds.

Exterior work often reaches other specialties. Enlarging an opening may require structural design. Moving wiring, signs, vents, plumbing, or security devices can involve licensed trades. Disturbing older coatings, sealants, siding, insulation, or wall materials may require lead-based paint or asbestos review before demolition. Wet sheathing or framing may need moisture, mold, or structural follow-up. Put those tasks in sequence rather than expecting one facade bid to cover every consequence.

Budget immediate work, later maintenance, and a reserve separately. Add access, design, permits, testing, restoration, tenant coordination, and the cost of areas that could not be examined. Do not make a known exterior cost disappear by assuming higher rent, full occupancy, appreciation, lower utility bills, an insurance payment, or refinancing. None of those outcomes is guaranteed.

Plan occupied work with consistent procedures

For an occupied property, identify how inspection and construction will affect notice, entry, window coverings, personal belongings, weather protection, security, noise, dust, entrances, and temporary loss of a room or doorway. The property manager and Michigan attorney should review lease duties, lawful access, repair communication, temporary arrangements, and accommodation requests before the schedule is promised. Contractors control the work zone; they do not decide the housing provider's legal obligations.

HUD states that the Fair Housing Act prohibits housing discrimination because of race, color, national origin, religion, sex, familial status, or disability. Use written, consistent procedures for inspection access, repair priorities, temporary protection, communication, and accommodation review. Base the work on documented building conditions, lease rights, qualified recommendations, and applicable law rather than a tenant's protected characteristics. Michigan and local protections may also apply.

Keep contracts and payments inside the IRA process

Ask the self-directed IRA custodian how specialist inspections, access equipment, contractor deposits, permits, repairs, warranties, refunds, and insurance proceeds must be authorized and paid. Confirm the purchaser name, signer, invoice wording, funding lead time, and change-order process. If the seller will complete work before closing, have the purchase agreement define the scope, contractor qualifications, permits, inspection rights, documentation, and response if concealed conditions change the job.

The IRS prohibited-transaction page, reviewed June 27, 2026, lists furnishing goods or services between a plan and a disqualified person among prohibited transactions and identifies buying property for present or future personal use with IRA funds as a possible IRA prohibited transaction. Do not assume the IRA owner can remove trim, apply sealant, replace a window, supply materials, supervise personal labor, or pay a contractor and seek reimbursement. The custodian, CPA, and attorney should review the people, contracts, work, signatures, and payment route before anyone acts.

No property, window, wall system, contractor, repair, ownership structure, or strategy is approved or endorsed by the IRS. Have your own self-directed IRA custodian, CPA, Michigan attorney, property inspector, qualified window and building-envelope professionals, licensed contractors, insurer, property manager, enforcing agency, and other advisors review the account, building, records, proposed use, and work before taking action.

Leave closing with an exterior file someone can use

Keep the elevation map, inspection reports, dated photographs, permits, final approvals, installation and repair records, product information, contractor credentials, scopes, estimates, warranties, tenant communications, custodian instructions, and closing documents together. Mark every opening, wall section, or concealed area that was not fully reviewed. Add follow-up dates for maintenance, warranty transfers, and accepted repairs so the next property manager does not have to reconstruct the exterior history from a few unlabeled photos.

Primary sources for the public-rule portions of this review include Michigan LARA's Building Permit Information and Code Books pages, HUD's Fair Housing Act overview, and the IRS retirement-plan prohibited-transaction guidance. They provide the general framework. The answer for one window, wall, permit, or occupied property comes from current records, field inspection, the responsible enforcing agency, and the buyer's own qualified professionals.
