Why Permits Protect You (Not Just Bureaucracy)

Many homeowners see permits as unnecessary hassle. Here's why they actually protect YOUR investment:

1. Ensures quality construction — Inspectors verify structural integrity, electrical safety, and code compliance. This catches dangerous shortcuts.

2. Protects your insurance — If unpermitted work causes damage (fire from bad wiring, collapse from bad framing), your insurance may deny the claim.

3. Avoids sale problems — Unpermitted work must be disclosed when selling. Buyers can demand you obtain retroactive permits (expensive) or reduce the price.

4. Prevents fines — Massachusetts towns can issue stop-work orders and fines of $100 - $1,000 per day for unpermitted construction.
