A realistic HOA siding budget is built line by line, not guessed at as a lump sum — and the single biggest reason re-cladding projects blow through reserves is a budget that left lines out. This page is a self-directed worksheet your board or community manager fills in yourselves: a structured set of cost categories — wall area and building count, tear-off and disposal, substrate-repair contingency, weather-resistive barrier and flashing, cladding and trim, finish, permits, staging and access, resident communication, project management, and a reserve contingency percentage — each with a blank to enter your own numbers once you have bids. It is meant to be printed or saved and worked through, not a record of any project Sierra Siding has priced; we launched in 2026 and this is a planning tool, so every line is a fill-in ($______), never a fabricated figure. Used well, it turns a vague "we need new siding" into a defensible number the membership can trust. When you're ready to put real numbers against your buildings, schedule an HOA or multifamily exterior assessment.
How to use this worksheet
Print this page or save it, then work top to bottom, filling each blank as bids and your reserve study give you real figures. Don't try to complete it from memory — the value is in making sure no cost category is missing, so that when you compare proposals nothing returns later as a change order against the reserve. Fill in the quantity lines first (wall area, building count), then attach a dollar line to each scope category once contractors have priced the same written scope. Keep the contingency lines honest: a budget with no contingency isn't conservative, it's incomplete. For the larger decision this budget supports, our HOA exterior renovation guide frames the lifecycle, and for normalizing the bids that fill these blanks, use our HOA siding bid comparison guide.
Line 1 — Wall area and building count (the quantity basis)
Every dollar line downstream scales off how much wall there actually is, so start by quantifying it. Record total wall area to be re-clad (____ sq ft), the number of buildings (____ buildings) and stories, and any unusual access conditions — tight setbacks, multi-story elevations, balconies — that change labor. If you don't have measured areas, note that the bidders' site walk should establish them, because a budget built on a rough guess of square footage is a budget that will move. This quantity basis is what lets you sanity-check whether a per-unit bid is reasonable. For sizing the larger investment, our siding cost in California page covers the general market ranges that frame expectations without standing in for your bids.
Line 2 — Tear-off and disposal
Removing the existing cladding and legally disposing of it is real, separate cost that thin bids sometimes fold invisibly into a single number. Record a line for tear-off labor and a line for haul-off and disposal (Tear-off & disposal: $______). Older communities may carry added cost if the existing material requires special handling, so flag that as a question for your bidders rather than an assumption. Keeping this as its own line is what lets you compare proposals honestly — a bid that doesn't separate it is a bid you can't fully level. Our HOA exterior renovation process page shows where tear-off falls in the sequence and why what it reveals matters to the next line.
Line 3 — Substrate-repair contingency (the line boards forget)
This is the single most commonly under-budgeted line, and the one that most often triggers a mid-project special assessment. Tear-off reveals what aged cladding was hiding — dry rot, failed prior flashing, damaged sheathing — and none of it is visible when bids are written. Rather than pretend it isn't there, carry an explicit substrate-repair contingency (Substrate-repair contingency: $______) sized to the age and condition of your buildings, and confirm in the contract how found rot will be priced and approved. A budget that assumes zero hidden damage on a thirty-year-old community is a budget designed to fail. Our cost of delaying HOA siding replacement page explains why the older the cladding, the larger this contingency needs to be.
Line 4 — Weather-resistive barrier and flashing
The assembly that actually keeps water out for decades — the weather-resistive barrier and the flashing at every window, door, transition, and penetration — is invisible once cladding covers it, which is exactly why it deserves its own budget line rather than being buried in "installation." Record it explicitly (WRB & flashing: $______). This is the highest-leverage quality investment in the whole project, because a barrier or flashing shortcut won't fail at final inspection but will surface as a defect claim years later. Make sure every bid prices the same barrier and flashing approach so this line is comparable. Our HOA siding bid comparison guide shows how to normalize bids around exactly these hidden-but-critical scope items.
Line 5 — Cladding, trim, and finish
This is the visible material and labor most people think of as "the siding," and it usually splits into a few lines: the cladding system itself, trim and corner boards and fascia, and the finish. Record the cladding and trim line (Cladding & trim: $______) and, separately, the finish line (Finish / ColorPlus: $______), because factory finish versus field paint changes both cost and long-term maintenance. Sierra Siding installs James Hardie fiber cement and LP SmartSide engineered wood; the product choice affects this line and the manufacturer guidance at James Hardie sets what correct installation requires. Tie the finish decision back to lifecycle cost, since a longer-lasting factory finish lowers the repaint line in future reserve cycles.
Line 6 — Permits, staging, access, and resident communication
These are the project's enabling costs, and they're easy to forget until they show up. Carry a line for permits and any required inspections (Permits: $______), a line for staging and access — scaffolding, lifts, dumpsters, protection of landscaping and walkways (Staging & access: $______) — and a line for resident communication, because notices, signage, and the manager's coordination time are real costs of a community project (Resident comms: $______). For multi-building sites these scale with phasing, so price them against your actual sequence. Our resident communication during construction page details what that comms line is buying you in avoided friction.
Line 7 — Project management and oversight
A community-scale exterior project needs someone owning the schedule, the milestone walkthroughs, the change-order approvals, and the closeout documentation — whether that's the contractor's project management built into their bid, the community manager's time, or both. Record it as an explicit line (Project management / oversight: $______) rather than assuming it's free. Under-resourcing oversight is how quality problems and disputes slip through, so a board that budgets for it is protecting the rest of the investment. Our HOA contractor evaluation checklist helps you judge whether a bidder's project-management approach is credible, and our questions to ask a siding contractor page surfaces how they handle oversight day to day.
Line 8 — Reserve contingency and the total
Finish with an overall contingency expressed as a percentage of the subtotal (Reserve contingency: ____% = $______), separate from the substrate-repair line in Line 3 — this one covers the unknowns that aren't substrate, from weather delays to scope refinements. A modest, explicit contingency is what keeps a project from becoming a special assessment when reality differs slightly from the plan. Sum every line above plus the contingency to reach your planning total ($______), and carry that number — not a single bid number — into the reserve discussion and the membership conversation. Our protecting reserve funds and avoiding special assessments pages explain why a contingency-inclusive total is the one that protects the community.
Key takeaways
- A defensible HOA siding budget is built line by line; the lump-sum guess is what blows through reserves
- This is a printable, fill-in-yourself worksheet — every figure is a blank ($______) you complete from your own bids, not a price we've set
- Quantify wall area and building count first, because every dollar line scales off the quantity basis
- The substrate-repair contingency is the most-forgotten line and the top cause of mid-project special assessments
- Give the weather-resistive barrier and flashing their own line — it's the highest-leverage quality investment and easy to bury
- Permits, staging, resident communication, and project management are real costs that scale with phasing on multi-building sites
- End with an explicit reserve contingency percentage and carry the contingency-inclusive total — not a single bid number — to the membership

Quick Answers
Neither. It's an on-page worksheet you read, print or save, and fill in yourself. There's nothing to download and no email gate — the cost categories and blank lines are right here for your board or manager to work through directly.
Sierra Siding launched in 2026, and we won't print fabricated figures as if they were real prices. Real costs depend on your wall area, building condition, materials, and access, so every line is a blank ($______) you complete once you have bids scoped to your specific community.
The substrate-repair contingency. Tear-off reveals hidden dry rot, failed flashing, and damaged sheathing that no bid can see in advance, and a budget that assumes zero hidden damage on an aging community is the one most likely to trigger a mid-project special assessment.
That's a board decision informed by the age and condition of your buildings and your reserve study, which is why the worksheet leaves it as a percentage you fill in. The principle is that a budget with no contingency isn't conservative — it's incomplete — so carry an explicit, honest number rather than zero.
From bids scoped to the same written scope of work and from your reserve study. Normalize the proposals using our bid comparison guide so each contractor is pricing the same buildings and the same barrier, flashing, and material approach, then transfer those leveled figures into the worksheet lines.
Yes. A community-scale project needs someone owning the schedule, walkthroughs, change orders, and closeout — whether that's the contractor's built-in project management, the community manager's time, or both. Budgeting for it explicitly protects the rest of the investment from the quality problems that under-resourced oversight invites.
The contingency-inclusive planning total from the bottom of the worksheet, not a single bid's headline number. A total that already accounts for tear-off, hidden repairs, the hidden barrier work, enabling costs, and contingency is the one that survives contact with reality and keeps a special assessment off the table.
