What goes in the record
The complete addition documentation:
- PP&D permit set — the issued plans and structural drawings.
- Certificate of Occupancy — the legal document.
- Sub-permit finals — electrical, plumbing, mechanical sign-offs.
- Structural engineer's letter — confirmation that the as-built work matches the stamped drawings.
- Energy compliance — REScheck or prescriptive summary, blower-door and duct-test results.
- Asbestos clearance (if abatement happened) — DEQ paperwork.
- Lead RRP records (if applicable) — EPA-required documentation.
- Survey — the boundary and topographic survey.
- Geotech report (if obtained).
- Construction photos — milestone shots, especially in-wall photos before drywall (where pipes, wires, and structure are visible — invaluable for future repairs).
- GC contract and warranty paperwork.
- Lien waivers — final unconditional waivers from GC and every sub.
- Sub list — names, license numbers, contact info for every trade who worked on the project.
- Equipment manuals and warranties — HVAC, water heater, appliances.
- Allowance true-up record — what was selected for each allowance line, what it cost.
Why this matters
Three audiences will eventually want this record:
- Future you. When you re-roof in 12 years, you'll want to know what the roof structure looks like. When a faucet leaks, you'll want to know which sub installed it. When the HVAC needs warranty service, you'll want the paperwork.
- A buyer. When you sell — even 20 years from now — buyers and their inspectors will ask whether the addition was permitted. The CofO and the permit set are the answer.
- Your insurer. Major additions often trigger policy reviews. The CofO confirms the work was permitted; the as-built square footage updates the policy limits.
Where to keep it
Two copies, both digital:
- Cloud storage (Google Drive, Dropbox, etc.) in a clearly named folder with sub-folders by document type.
- Local backup on an external drive or family NAS.
Paper-only home records are how documentation gets lost in moves, fires, and basement floods. Go digital, with a clear folder structure that someone other than you can navigate.
A note on what HomePlan stores
HomePlan's home record (Phase 2+ feature) is designed to hold exactly this set of documents — event-sourced, permanent, attached to the physical address rather than the account. For now, organize it yourself with a date-stamped folder structure and you'll be ready when the platform feature lands.
