A Lakewood rental property deck that was built in the 1970s or 1980s has likely never been structurally assessed. Original hardware has corroded. Ledger boards were installed without flashing. Post bases have been sitting in ground contact for 40 to 50 years of Pacific Northwest moisture. The deck looks functional until the day it doesn't. A forensic diagnostic identifies every compromised member. A fixed-price contract repairs the structure permanently — before a tenant becomes the load test.
The $350 forensic diagnostic covers ledger board condition and flashing status, post and post base integrity at every support point, beam and joist assessment including hardware connections, and an overall structural rating. Written findings report delivered. The $350 credits 100% toward repair. No open bids. No scope surprises after demo begins.
These are observable indicators of structural compromise. Each one represents a failure mode that has been developing over years — not a cosmetic condition that appeared recently.
A structurally sound deck platform is rigid under dynamic load. Visible movement, flex, or bounce when occupants shift weight indicates that one or more primary structural members — ledger, beam, or post — is no longer carrying load as designed. In Lakewood's 1970s-era rental housing, this symptom most commonly traces to ledger fastener corrosion or post base deterioration. Neither condition stabilizes without repair.
The ledger board is the structural connection between the deck and the house. Any visible gap, separation, or pulling away at this joint is a critical structural finding — not a caulking issue. In Lakewood rental properties built before current IRC ledger attachment standards, this connection was made with fasteners that have now corroded through decades of Pacific Northwest moisture. A separated ledger is a collapse precursor.
Deck posts in Western Washington that show dark staining, visible softness, or any lateral movement at the base are in active structural failure. Post base rot in Lakewood's rental stock is common — original posts were installed in direct soil contact or on surface-mount hardware that has since corroded. A post that moves under hand pressure is not carrying its design load. The beam and joists above it are compensating through adjacent members not designed for that redistribution.
Metal joist hangers that have visibly pulled away from the ledger or beam — even fractionally — indicate that the fasteners anchoring them have either corroded through or are pulling out of deteriorated wood. This is a hardware-and-material failure, not a fastener-tightening issue. The condition affects every joist connected to that hanger row and represents a simultaneous loss of load path across the full deck width.
A significant portion of Lakewood's rental property decks were built without permits during the 1970s and 1980s — owner-built additions that were never inspected to current structural standards. An unpermitted deck has no inspection record, no hardware compliance documentation, and no structural baseline. For a Lakewood landlord, an unpermitted deck represents both a habitability liability and a sale impediment. The forensic diagnostic establishes the actual structural baseline regardless of permit history.
Dark staining or visible soft spots on joists, beams, or the ledger board itself — visible without disassembly — confirm active or advanced fungal decay. In Lakewood's climate, once visible decay is present on the surface of a structural member, the interior of that member has been compromised for at least one to two seasons. Surface-visible rot on a structural member means the member is not carrying its design load and must be replaced, not treated.
Deck structural repair is a defined GC scope under WAC 296-200A-016(23). Understanding the boundary prevents scope misalignment before the contract is written.
The forensic diagnostic evaluates every primary structural member independently. Risk classification determines repair priority and scope sequencing in the fixed-price contract.
| Member | Primary Failure Mechanism — Lakewood Stock | Failure Consequence | Risk Level |
|---|---|---|---|
| Ledger Board | No flashing at house connection; fastener corrosion through rim joist; wood decay at direct contact with house sheathing | Full deck separation from house — collapse event, not a gradual failure | Critical |
| Posts | Original ground contact or surface-mount corrosion; untreated lumber at base; soil grade raised against post over decades | Post compression failure causes beam drop and platform tilt; accelerates at high-load events | Critical |
| Post Bases & Hardware | Non-galvanized original hardware corroded through; standoff height inadequate; base plate in direct water contact | Post lateral stability lost; deck can rack under lateral load (occupant movement, seismic) | Critical |
| Beam | Moisture accumulation at post-beam connection; lack of positive drainage at bearing point; fastener pull-through in deteriorated post tops | Beam drop at post connection; load redistribution to adjacent posts at above-design capacity | High |
| Floor Joists | Joist hanger corrosion; ledger-end joist rot from water intrusion at ledger; bearing point soft rot at beam contact | Localized deck platform deflection; progressive hanger pull-through under repeated load | High |
| Joist Hangers & Hardware | Original non-galvanized hardware corroded; inadequate fastener schedule; hangers undersized for current IRC joist span tables | Simultaneous hanger failure across full joist row; platform drop without prior visible warning | High |
| Rim Joist | End-grain moisture absorption at deck perimeter; surface decking fasteners wicking water into rim; paint or sealant failure | Decking fastener pull-through; rim joist connection failure at ledger ends | Moderate |
Four conditions specific to Lakewood's housing age, rental density, and Pacific Northwest climate concentrate deck structural risk in this market above the regional average.
The IRC prescriptive ledger attachment requirements — through-bolting, flashing, standoff hardware — were not standardized in Washington State's residential building code until the early 2000s. Lakewood decks built in the 1970s and 1980s were attached with methods that are now known to be inadequate: toenailed connections, unflashed ledgers against house sheathing, and fasteners that are now 40 to 50 years into corrosion exposure. The attachment method that was legal at the time of construction is a structural liability today.
Lakewood rental property decks are exterior systems that tenants use but rarely report on structurally. A tenant who notices a slightly bouncy deck surface attributes it to age and says nothing. A property manager conducting a turnover inspection looks at paint and flooring — not ledger hardware. The result is a structural system that deteriorates unobserved for 10 to 20 years between the original construction and the first competent assessment. By the time the assessment happens, multiple failure modes are operating simultaneously.
Western Washington's persistent humidity — 140-plus rain days per year in Pierce County — drives a hardware corrosion timeline that is dramatically faster than national building code assumptions based on drier climates. Non-galvanized or under-galvanized joist hangers, post bases, and ledger fasteners that carry a 25-to-30-year rated life in dry climates reach end-of-service in 15 to 20 years in Lakewood's exposure environment. A deck built in 1985 with code-compliant hardware of that era has hardware that has been past its functional service life since approximately 2005.
A significant percentage of Lakewood's rental property decks were owner-built additions that were never permitted or inspected. These structures were built to the original owner's judgment — not to prescriptive code. Post spacing, ledger attachment, hardware selection, and beam sizing were all made without plan review or field inspection. For a current Lakewood investment property owner, an unpermitted deck is a documented liability gap: no inspection record, no structural baseline, and no permit documentation to satisfy a buyer or lender. The forensic diagnostic is the only way to establish the actual structural condition of a deck with no permit history.
Four stages. The fixed-price contract is written before any structural member is touched. No scope additions after the ledger comes off the wall.
Full structural assessment of every primary member: ledger attachment method and condition, post integrity and base hardware at every support point, beam bearing condition, joist and hanger assessment, rim joist condition. Written findings report with member-by-member status. Structural risk classification for each identified failure mode. $350 credited 100% toward repair if you proceed.
Each compromised member identified in the diagnostic is assigned a repair or replacement specification. Ledger replacement includes through-flashing specification. Post replacement includes hardware upgrade to current ICC-ES approved standoff bases. Hardware replacement specifies hot-dipped galvanized or stainless at all connections. One fixed price — not a range, not a T&M estimate. Scope does not expand after the contract is signed.
APCON LLC (GC License #APCONL*825QO) pulls the permit through the City of Lakewood. Temporary shoring installed before any primary member is removed. Compromised members replaced in full to current IRC specification — no partial repairs on members past structural threshold. All hardware upgraded to current code at replaced connection points. Flashing installed at ledger per current IRC prescriptive requirements. Framing completed and staged for inspection.
Structural framing inspection passed through Lakewood's building department. Permit closed with full documentation record. Five-year written structural guarantee on all APCON LLC work issued at project close. Documentation package — permit record, inspection sign-off, written warranty — provided in format suitable for lender, buyer disclosure, or property management file. Unpermitted deck status resolved by the permit and inspection record on the repair.
Every deck structural repair completed by APCON LLC carries a five-year written guarantee against structural failure attributable to our workmanship or materials.

WA GC License #APCONL*825QO.
Deck structural failure is not a gradual cost escalation problem — it is a liability event problem. Four consequences apply specifically to Lakewood investment property owners who defer structural assessment.
Washington State's implied warranty of habitability (RCW 59.18.060) requires landlords to maintain all structural elements in a safe and sound condition. A tenant injury on a structurally compromised deck creates direct premises liability exposure. The critical factor in any liability claim is whether the landlord knew or should have known of the condition. An uninspected 1970s deck on an occupied rental property — absent any inspection record — does not satisfy "should have known." The $350 diagnostic plus a fixed-price repair contract is the complete documentation of due diligence. APCON LLC does not provide legal advice — consult a licensed Washington State attorney.
Unlike subfloor deterioration — which produces soft spots and odors before structural failure — ledger board and post base failures in deck systems frequently produce no observable precursor symptoms. The ledger fasteners corrode through across all connections simultaneously. The post base corrodes to the failure threshold across all posts in a common exposure environment. The failure mode is sudden, not gradual. This is the structural condition that produces the deck collapse events that become news — and the reason that a structural assessment on an uninspected Lakewood rental deck is not optional maintenance but a risk management baseline.
A Lakewood investment property sale with an unpermitted or structurally flagged deck will not close with FHA or VA financing — and increasingly not with conventional financing — until the deck structural condition is documented and repaired. A buyer who discovers an unpermitted deck during due diligence has grounds to renegotiate price or exit the transaction. Resolving this during a vacancy window — not under contract pressure — produces better repair economics and a cleaner transaction.
The ledger board is physically attached to the house rim joist. Fungal decay that initiates in the ledger does not respect the boundary between deck and house framing. Active rot at the ledger connection point migrates into the rim joist, adjacent floor joists, and in advanced cases into the mudsill below. A deck structural repair that is deferred long enough becomes a dry rot remediation project that includes the house structure — a materially larger scope at materially higher cost.
Licensing & Regulatory Notice: Deck structural repair — including ledger board replacement, post and post base replacement, beam and joist repair, and hardware upgrades — is structural framing work performed directly by APCON LLC under Washington State General Contractor License #APCONL*825QO pursuant to RCW 18.27 and WAC 296-200A-016(23). Deck surface boards, railing systems, and finish work are outside this structural scope and are referred to appropriate licensed contractors. Any electrical work on or adjacent to the deck is performed exclusively by a licensed electrical contractor under GC coordination per RCW 19.28. APCON LLC does not hold or advertise specialty trade licenses. Realty Repair Co. is a registered trade name of APCON LLC.
The $350 forensic diagnostic assesses every structural member — ledger, posts, post bases, beams, joists, hardware — and delivers a written fixed-price repair contract before any work begins. The $350 credits 100% toward the repair. The permit and inspection sign-off produces the structural documentation record your tenant, lender, and next buyer require. Do not let the next load event be the inspection.
