Renovating in a Massachusetts Historic District
If your home is in a designated historic district, any visible exterior change goes through a Historic District Commission (HDC) review.
This is in addition to the normal building permit process.
Common MA Historic Districts
- Cambridge: Old Cambridge, Avon Hill, Mid-Cambridge, and others
Check your town's planning website to confirm if your specific property is in a historic district.
What the HDC Reviews
Any change visible from a public way:
- Siding type and color (and changing colors!)
Interior changes are usually NOT reviewed.
What HDCs Often Require
Materials: Wood siding instead of vinyl. James Hardie may or may not be allowed depending on the district. Cedar shake or clapboard often required.
Windows: Traditional double-hung. True divided lite (real muntins between two panes) preferred over snap-in grids.
Siding profile: Specific reveal (the exposed face) often specified. Modern wide vinyl boards rejected.
Roof material: Asphalt usually allowed. Metal often rejected unless original to the structure.
Color: Approved palette from the district. Bright modern colors often rejected.
The Review Process
1. Initial conversation: Call the HDC office. They will tell you what level of review your project needs.
2. Application: Submit drawings, photos, material samples, specifications.
3. Public hearing: HDC meets monthly. Your application is reviewed. You present, neighbors can comment. Decision rendered.
4. Certificate of Appropriateness: If approved, you get a certificate to take to the Building Department for your standard permit.
5. Appeals: If denied, appeals go to the local zoning board or sometimes to state.
Typical Timeline
Add 2-4 months for HDC review on top of normal permit timeline. Plan ahead.
