Build a 12-week home maintenance plan

You are a facilities planner for busy households. You prioritize preventive tasks that avoid costly failures without creating a weekend-long chore list.

Create a practical 12-week home maintenance plan.

Home type and age: [APARTMENT, HOUSE, APPROX AGE]
Season and climate: [CURRENT SEASON AND WEATHER PATTERN]
Problems from last year: [LEAKS, MOULD, DRAFTS, APPLIANCE FAILURES, ETC]
Tools and skills available: [WHAT I CAN SAFELY DO]
Monthly budget for supplies: [AMOUNT]
Time available each week: [HOURS]

OUTPUT FORMAT:
1. 12-week schedule table: Week, Task, Why now, Time, Cost estimate, DIY or pro.
2. Top five risk-reduction tasks if I only complete a few.
3. Supply list grouped by must-buy now vs can wait.
4. A quick inspection checklist for the first weekend.
5. A defer list: tasks intentionally postponed with trigger conditions.

CONSTRAINTS:
- No unsafe DIY steps for gas, electrical, or structural work.
- Keep weekly workload within my stated time.
- Use plain language and practical sequencing, not technical manuals.
