HOA & condo construction,
done by the statute.
The 8-phase playbook we run for boards and property managers across the Puget Sound — reserve alignment, owner notice, bid leveling, insurance, lien controls, and warranty handoff — with the actual RCW chapters that govern each step.
Eight phases. In this order.
Reserve study alignment
Before any RFP, pull the most recent reserve study (RCW 64.34.380 / 64.38.065 require one every three years for most associations). Map each candidate scope — roof, siding, decks, balconies, plumbing risers, paving — to its remaining useful life and funded balance. A project that runs ahead of the reserve schedule needs a board resolution + (often) a special-assessment vote before scope can be issued.
RCW 64.34.380 — Reserve Studies ↗Owner notice & vote thresholds
WUCIOA (RCW 64.90) and WCA (RCW 64.34) set strict notice windows: 14–60 days for special meetings, supermajority for special assessments over 5% of annual budget, and unanimous consent for changes to limited common elements (private balconies, decks, patios). Document every notice in the meeting minutes — courts have voided assessments on bare technicalities here.
RCW 64.90 — WUCIOA ↗Engineer / architect of record
For envelope work (roof, siding, deck waterproofing, plumbing risers), retain a licensed Washington PE or AIA architect to write the scope and bid documents — not the contractor. This is the single biggest cost-control lever in HOA work; contractor-written scopes routinely come in 30–60% higher because they bake in margin against scope ambiguity.
Bid leveling on identical scope
Issue identical bid packages to 3+ pre-qualified GCs (verified L&I, $2M+ liability, $5M+ aggregate, completed at least three multifamily projects in the last 36 months). Require itemized line-item pricing on a common schedule of values. The low bid is rarely the right bid — a leveled bid sheet shows you where each contractor is high, low, or missing scope.
Owner communication plan
Publish a phased construction schedule with: dates per building, daily working hours (most Puget Sound cities cap at 7am–7pm weekdays, 9am–7pm Saturday, none on Sunday), parking impacts, balcony/deck access loss windows, and a single point-of-contact email. Send weekly updates. The #1 source of HOA construction disputes is poor owner notice, not the construction itself.
Insurance & additional-insured endorsements
Require the GC to add the association AND the management company as additional insureds on the GL and umbrella policies for the project duration plus 2-year completed-operations tail. Require waivers of subrogation. Confirm the association's master policy covers occupied-unit work — many policies exclude construction defect.
Lien-release controls (multifamily critical)
Mechanic's liens on a multifamily building hit every unit owner pro-rata. Require conditional waivers (RCW 60.04 Form A) with every progress draw from the GC AND every named sub/supplier. Final 10% retention released ONLY upon delivery of unconditional final waivers from the full chain. This single clause prevents the most expensive HOA construction surprise.
RCW 60.04 — Mechanics' Liens ↗Punch & substantial completion
Substantial completion is a contractual milestone — define it in writing: punch list mutually agreed, certificate of occupancy issued where applicable, all manufacturer warranties registered in the association's name (not the contractor's), as-built drawings delivered, and a 2-year walkthrough scheduled in the contract. Without these, warranty enforcement falls apart at month 13.
What the work actually costs.
| Scope | 2026 Puget Sound range |
|---|---|
| Roof replacement (4–12 buildings) | $18–$42 per sqft installed; add $3–$8/sqft for sheathing replacement common in 1990s-era Puget Sound stock. |
| Siding replacement (LP/T1-11 → fiber cement) | $22–$38 per sqft installed; include rain-screen assembly and new flashings — code change since most original installs. |
| Deck & balcony waterproofing | $45–$90 per sqft for full tear-off, joist sister, new membrane, and rail. ANSI A1264 inspection on every balcony per WAC 51-11R (post-2018). |
| Plumbing riser replacement (PB / poly-B failures) | $2,800–$5,500 per stack-floor; phase by stack with 2-day owner notice and bottled-water plan. |
| Paving / parking lot mill & overlay | $3.50–$6.20 per sqft mill & 2" overlay; full reconstruct $9–$14/sqft. Stripe + ADA per WAC 51-50 Ch 11. |
| Exterior paint (full envelope) | $4.20–$7.80 per sqft of wall, includes prep, primer, two-coat acrylic. 10–12 yr cycle in PNW; 6–8 on south/west exposures. |
| EV charging infrastructure | $3,500–$8,500 per stall installed (Level 2); WAC 51-11 now requires EV-ready conduit in new MF construction. |
| Common-area HVAC / boiler replacement | $45–$95 per unit served for high-efficiency condensing replacement; coordinate with WA energy code compliance path. |
Ranges blend our last 36 months of Puget Sound multifamily bids with regional reserve-study benchmarks. Exclude design fees (5–10%), permits, and reserve contingency (10–15% recommended).

Frequently asked
When does an HOA need a special assessment vote vs. board approval?
Under WUCIOA (RCW 64.90.480), any expenditure exceeding 5% of the association's annual budget requires owner approval — typically a majority of votes cast at a meeting with quorum. Older WCA associations (RCW 64.34) often have lower thresholds in their CC&Rs (sometimes 3%). Read the declaration first; statute is the floor, not the ceiling.
Can the board bypass an owner vote by phasing the project across multiple budget years?
No. Washington courts treat artificial phasing to avoid the assessment threshold as a breach of fiduciary duty under RCW 64.34.308. If the work is functionally a single capital project, it counts as one expenditure for the vote test — even if invoiced across two fiscal years.
Does the association need a permit for roof, siding, or deck replacement?
Yes — every Puget Sound city requires a building permit for roof tear-off, siding replacement, and deck/balcony repairs that touch structural members. Seattle SDCI typically issues these as Standard Plan permits in 4–8 weeks. Bellevue, Tacoma, Kirkland, and Redmond similar. Painting and in-kind window replacement (no header change) are usually exempt.
Who is liable if a contractor's sub files a lien on the building?
Every unit owner — pro-rata by undivided interest. Mechanic's liens under RCW 60.04 attach to the entire common-element parcel, and the lien claimant can foreclose. Only conditional waivers from every tier (GC, subs, suppliers, rental yards) at every draw protect the association. This is non-negotiable.
What insurance limits should we require on a $1M+ envelope project?
Minimum: $2M general liability per occurrence / $4M aggregate, $5M umbrella, $1M auto, $1M workers' comp employer's liability. For multifamily over 4 stories or projects over $5M, scale to $5M/$10M GL and $10M umbrella. Require the association and management company as additional insureds with primary/non-contributory language, plus 2-year completed-operations tail.
Should we use a construction manager (CM) or go directly to a GC?
For projects under $750K, direct-to-GC with an architect-of-record is usually sufficient. For projects $750K–$3M, an owner's-rep CM (3–5% of construction cost) typically saves more than they cost through bid leveling, change-order discipline, and warranty enforcement. Above $3M, a CM is essentially mandatory.
