- An addition
- Significant structural repairs

If you’re unsure, contact the permit office before work begins.

Siding Replacement
Simple replacement of exterior siding may be treated differently from structural alterations.
If the project changes the structure, involves an addition or includes other construction, additional permits may be required.
Because requirements vary by jurisdiction, check with the building department serving your property before beginning a major siding project.

Storm Damage Repairs
Roof and siding repairs are common after hail, wind and severe storms.

- Get a written estimate.
- Verify exactly what work will be completed.
- Ask who is responsible for obtaining required permits.
- Check whether structural damage is present.
- Keep photos and documentation for insurance purposes.

- Roofing materials
- Shingle colors
- Siding materials
- Exterior colors
- Architectural changes
Check your HOA requirements before ordering materials or beginning work.
