Frequently Asked Questions
Q: Can all unpermitted additions be legalized?
A: Most can be brought into compliance, but some may require modifications to meet current codes. In rare cases, removal may be necessary if the addition violates zoning or setback requirements.
Q: Will I get in trouble for having an unpermitted addition?
A: Building departments want compliance, not punishment. Voluntarily addressing the issue shows good faith and typically results in cooperation rather than penalties.
Q: Do I need to hire the original contractor?
A: No. PermitPatch works with licensed professionals to obtain retroactive permits regardless of who did the original work.
Q: Will my property taxes increase?
A: Possibly. Once permitted, the addition becomes part of your official square footage and may increase assessed value.
