The Central Street District was listed on the National Register of Historic Places in 1982. The listing alone doesn't tell you what local review applies.
That gap between "listed" and "regulated" is the thing most people get wrong about historic property in Andover, and it matters if you're buying an older home here, planning to sell one, or thinking about work on one you already own.
Three Bodies, Three Very Different Powers
Andover doesn't have one historic review process. It has three, and they don't all apply to the same houses in the same way.
The Ballardvale Historic District Commission covers the old mill village centered on Andover Street, with Center, Marland, Dale and High Streets laid out in an 1848 subdivision, plus portions of High Vale Lane, Chester, Oak and Tewksbury Streets and Clark Road, as the Ballardvale Historic District listing describes. If your house sits inside that footprint, some exterior work may require a Certificate of Appropriateness before the town will issue a building permit, as the town's Ballardvale commission guidance explains. The commission’s review authority dates to the district’s establishment in 1995, though, as the town’s March 16, 2026 update explains, the revised bylaw now exempts some work.
The Central Street Historic District Commission covers properties with frontage on Central Street between Phillips Street and Essex Street, as the Central Street District entry on Wikipedia describes. This is the newer authority, created by Town Meeting vote in 2025.
The Andover Preservation Commission operates differently. The town's Preservation Commission guidance says it reviews exterior changes to individually listed properties, from siding and windows to rooflines and chimney removal, but not interior work, paint color, or routine maintenance. Its sharpest tool is a demolition delay of up to twelve months on buildings it finds historically significant, and it has been credited with saving the oldest house in Andover from the wrecking ball, according to the Andover Preservation Commission page.
| Authority | What triggers review | What it can require |
|---|---|---|
| Ballardvale Historic District Commission | Potential review of exterior work inside the mapped district | For non-exempt work, a Certificate of Appropriateness before a building permit is issued |
| Central Street Historic District Commission | Exterior work on Central Street-fronting properties, Phillips to Essex Street | Exterior review may apply |
| Andover Preservation Commission | Exterior changes to individually listed properties, or demolition of a building found historically significant | Up to a 12-month demolition delay; recommendations on exterior changes |
A house can be old, photogenic, and locally beloved without triggering any of this. It can also be a modest ranch that happens to sit inside a mapped district boundary and face the same review as the grandest Victorian on the street. Age and architecture aren't the trigger. The address is.
The Bylaw Just Got Rewritten, and That Matters for Timing
Andover's Select Board voted 5-0 in March 2026 to recommend the first major revision to the Ballardvale bylaw since it was written in 1995, and Town Meeting approved the update on April 28 and 29, 2026. The process behind it ran through five publicly televised commission meetings, a community survey that drew 206 responses, and two public forums for Ballardvale residents.
The rewrite didn't loosen everything. It added specific exemptions from commission review: retaining walls under four feet, solar panels, satellite dishes, and other work that doesn't already require a building permit. It also introduced an expedited approval track for applicants who make the changes the commission asks for, rather than starting the clock over. For anyone planning pre-listing exterior work on a Ballardvale home this fall or next spring, that expedited path is worth knowing about before you schedule a contractor.
What the rewrite didn't touch is the underlying authority itself. A Certificate of Appropriateness is still required for covered exterior work before the town issues a building permit. Skip that step and the town can issue a stop-work order or a fine, on top of whatever it costs to fix.
How the commission applies its judgment came through clearly in resident feedback gathered before the rewrite. As Andover News reported, one Ballardvale homeowner described asking to replace windows that had already been swapped out in the 1970s on a house built in the 1890s, seeking better energy performance. The commission agreed the new windows would look indistinguishable from the street. It denied the request, citing the structural profile of the proposed replacement. That's the kind of outcome a rewritten exemption list for solar panels and short retaining walls doesn't change.
What This Actually Means Before You List or Renovate
If you own, or you're considering, a home inside Ballardvale or along Central Street, a few things follow directly from how these commissions work.
Check district status before you plan exterior work, not after. Some exterior work may need a Certificate of Appropriateness first. That approval step happens before the building permit, not alongside it, so it needs to be built into your renovation timeline months in advance of a spring listing, not the week before photos.
Don't assume National Register status means nothing regulates the property, and don't assume it means everything does. Some individually listed properties outside mapped districts may also be subject to the Preservation Commission's review.
Ask what specifically triggered any past review on a property you're considering. A previous owner's stop-work order, a denied application, or a demolition delay finding is the kind of history that shapes what you'll be able to do with the house, and it's worth surfacing in conversation with your agent and with the seller before you're deep into a purchase.
If you're weighing an addition or a major exterior renovation, look at whether the specific commission with jurisdiction over your address has recently updated its guidelines. Ballardvale's rewrite came with a promise of a separate, more detailed design guidelines document to follow the bylaw itself. That kind of update can change what's realistic to plan for a property years before you'd otherwise think to check.
A Few Common Questions
Does every old house in Andover need historic review before renovation? No. Historic review can apply to some older homes, but many older Andover homes fall under none of these three authorities.
My house is old but I don't think it's in a mapped district. What applies to me? A mapped district is not the only way a property may come under historic review; the Andover Preservation Commission also reviews exterior changes to individually listed properties.
How long does a Certificate of Appropriateness take? The research doesn't give a fixed timeline, and it will vary by project complexity and commission meeting schedule. The Ballardvale commission meets the first Wednesday of each month, and the 2026 rewrite added an expedited track for applicants responding to requested changes.
Historic character is one of the things that makes an Andover address worth a look, but the rules that come with it aren't the same from block to block or year to year. Knowing which commission has jurisdiction over a specific address, and how recently its rules changed, is the difference between a renovation timeline that holds and one that doesn't.
