Custom Build Checklist for Newfoundland

1 Run the federal rebate math first $50K

The Bill C-4 First-Time-Home-Buyer GST/HST rebate (Royal Assent March 13, 2026) returns up to $50,000 on the federal 5% GST portion. Eligible agreements: signed between March 20, 2025 and before 2031, substantial completion before 2036. Owner-built homes qualify — you file GST191 within 2 years of substantial completion.

Full math + examples: HST Rebate Guide.

2 Know what’s NOT recoverable ~$50K

NL has no provincial-portion HST rebate on owner-occupied new housing. The 10% NL provincial HST is not recoverable. On a $500K build, that’s ~$50,000 in provincial HST you will NOT get back. Budget for it. The federal rebate doesn’t cover everything.

3 Talk to a mortgage broker about progress-advance financing EARLY

CMHC progress-advance mortgages let you fund construction in stages alongside builder milestones. Requires pre-approval BEFORE work begins. The CMHC Full Service option includes 4 free CMHC-validated draws. Skip this and you may end up needing more expensive bridge financing mid-build.

• Talk to mortgage broker about CMHC vs Sagen vs Canada Guaranty for progress-advance options
• Confirm rate-hold length — standard 90-120 days; some lenders offer 6-9 months for new builds
• Stack with FHSA + HBP for down payment (see HST Guide for amounts)

4 If unserviced lot: engage ANLS surveyor + Approved Designer EARLY 12 months

Most rural and many semi-rural Avalon lots aren’t on municipal water + sewer. You’ll need:

• An ANLS-licensed surveyor to lay out the lot and confirm boundaries
• An Approved Designer for septic system design (Service NL requires this for systems over 4546 L)
• Well drilling + potability testing
• Crown lands (if applicable) has 12-month deadlines from approval — don’t wait until permit-pulling time

Central NL soil conditions vary widely — what works on one lot may not work on the adjacent lot. Get the soil assessment done before you commit to a lot you can’t actually build on.

5 Verify against the full builder-vetting stack CRITICAL

Before signing anything, verify your builder against every layer:

• AHWP enrolment — call 1-800-320-9880 to confirm member status AND that they’ll enrol YOUR specific home per-unit. Full AHWP guide.
• CHBA-NL member in good standing
• Workers’ Compensation registration current
• General liability insurance certificate (ask for proof)
• GST/HST registration number (any legitimate builder has one)
• Municipal contractor license (varies by municipality)
• BBB Atlantic record check + Google reviews of completed builds
• Talk to 2-3 previous buyers if possible — ask specifically about deficiencies, timeline accuracy, change-order handling

6 Get the all-in price IN WRITING

Pre-construction builders frequently quote a base price that doesn’t include lot premium, upgrades, finishes above builder-grade, appliance packages, landscaping, driveway, deck. Get the all-in price covering:

• Lot purchase price + any lot premium (walkout basement, corner, premium position)
• Base build with specified plan
• All selected finish upgrades (cabinets, flooring, fixtures)
• Appliance package OR allowance amount
• Landscaping scope OR allowance
• Driveway and deck specs
• HST handling (inclusive or plus + rebate handling)
• Any developer / HOA / community fees

And confirm: does the base spec change if you make selections later? (It usually does.)

7 Deposit in lawyer-held trust account REQUIRED

NL has ZERO statutory deposit protection (unlike Ontario’s Tarion or BC’s REDMA). Contractual is the only protection you get. Insist on:

• Lawyer-held trust account (your lawyer, not the builder’s) for deposit + staged milestone payments
• Written deposit schedule tied to verifiable milestones (foundation poured, framing complete, mechanical rough-in, drywall complete, occupancy)
• Refund triggers if build runs past contractually-agreed completion date
• If AHWP-enrolled: AHWP deposit protection layered on top (program limits apply)

Negotiating this costs essentially nothing. Skipping it shows up only when something goes wrong.

8 Engage real-estate lawyer experienced with builder agreements

Builder purchase agreements are different from standard resale APS forms. They include staged closings, change-order rules, builder delay clauses, finish-allowance schedules, warranty assignment language. Get the contract reviewed by a lawyer who’s seen this shape before — not your cousin who does wills.

9 Lock in rate-hold with mortgage broker

Once contract is signed, rate-hold clock starts. Confirm the hold length and any extension options. New-build rate holds typically run 90–120 days, but some lenders extend to 6–9 months for new construction. If your build is longer than the rate hold, plan extension OR refinancing strategy upfront.

10 Specify NECB 2020 Tier 2+ at DESIGN phase $3-5K DESIGN

NL adopted only NECB 2020 Tier 1 as the minimum. Tier 2 or higher unlocks the CMHC Eco Plus refund of $3,000–$5,000 (requires ENERGY STAR for New Homes OR EnerGuide ≥20% better than reference). Hire an energy advisor at DESIGN phase, not after framing — insulation, air-sealing, mechanical decisions all need to be made before walls go up.

NL is on the lowest energy tier in the country. Most NL builds aren’t qualifying for federal rebates that reward higher tiers. The marginal cost of building to Tier 2+ is modest; the rebate plus resale value over time more than covers it.

11 takeCHARGE NL pre-application before construction starts

takeCHARGE NL offers rebates on heat pump installations, insulation upgrades, smart thermostats, etc. Apply BEFORE installation — retrospective applications are usually denied. Stack with CMHC Eco Plus if eligible.

12 Track every invoice for the GST191 rebate filing $$

The owner-built rebate (GST191) uses receipted construction costs as the calculation base. Missing invoices = smaller rebate. Build a shoebox / folder / spreadsheet from day one. Materials, labour, professional services, contractor invoices, equipment rentals — all of it.

A tax professional experienced with GST191 will pay for themselves on this filing.

13 Hire an independent pre-delivery inspector

Separate from the builder’s walkthrough. Look for InterNACHI or CAHPI certified inspectors. Document deficiencies in writing — this list becomes part of the AHWP year-1 warranty claim record. The builder is generally obligated to rectify documented items within a defined window (typically 30–90 days for cosmetic, longer for structural).

14 Get occupancy permit + AHWP enrolment certificate IN HAND before closing

Both required. The occupancy permit (issued by your municipality) confirms the structure is safe to occupy. The AHWP enrolment certificate (from your builder) confirms the warranty has been formally activated for your specific unit. Both should be in your closing package.

15 File GST191 within 2 years of substantial completion 2 YRS

The hard deadline. Don’t miss it. The Bill C-4 FTHB rebate has its own substantial-completion deadline of before 2036 for agreements signed in the eligible window. Use a tax professional experienced with owner-built rebate filings — the math is complex (fair-market-value method vs receipted-cost method, materials supply vs labour, GST vs PST).
