TLDR
If your Montclair property is a local historic landmark or sits inside a local historic district, most visible exterior changes need a Certificate of Appropriateness from the Historic Preservation Commission before the building permit is issued, or before work starts if no permit is needed. Painting, interior work, changes the public can't see, and repairs or identical replacements that don't change the exterior appearance are exempt. Fences, awnings, lighting and paving can often go through a minor application without a public hearing. The Commission has 45 days from referral to report.
Montclair Historic District Rules: When You Need a Certificate of Appropriateness
Montclair has an unusually large stock of century-old houses and storefronts, and the Township protects a share of them through local designation. If you own one, the Historic Preservation Commission is part of your project whenever the work changes how the building looks from the street. Knowing which side of that line your job falls on, before you sign a contract, saves weeks and keeps you out of a stop-work notice.
Is Your Property Covered?
The Certificate of Appropriateness requirement in Montclair Code § 347-136 applies to two kinds of property: individually designated local historic landmarks, and any building, structure, site or object inside a designated local landmark district. Districts are designated in Montclair Code § 347-148.1 under the state Municipal Land Use Law (N.J.S.A. 40:55D-65.1).
The Township's Local Historic Districts page currently describes four districts:
- Pine Street Historic District: a largely residential, working-class neighborhood of 77 structures dating from the 1880s to the 1930s, including wood-frame houses and early-20th-century masonry buildings.
- Town Center Historic District: Montclair's largest commercial district, 176 structures from the 1840s to the 1960s, much of it along Bloomfield Avenue.
- Upper Montclair Business Historic District: 93 historic structures, mostly one- and two-story commercial buildings with retail below and offices or apartments above.
- Watchung Plaza Historic District: 24 historic structures around the Watchung Avenue station, plus Watchung Plaza Park and Watchung Park.
Individual landmarks can be anywhere in town, including on streets with no district. The Department of Planning & Community Development maintains a Historic Inventory Viewer, an interactive map of local districts, local landmarks and other areas identified in the Master Plan's Historic Preservation Element. Look your address up there before you plan anything. If the map is unclear, call Planning at the Municipal Building (205 Claremont Avenue, 973-744-1400) and ask whether your block and lot is designated.
One thing to watch: a house can show up on the inventory for demolition purposes without being a local landmark. The demolition rules in § 347-142.1 use a broader definition of “historic structure” that also covers federally or state-designated districts and properties with a documented survey identified in the Master Plan. If any part of your project removes a facade or a large share of the exterior walls, read that section or ask Planning directly.
Work That Needs a Certificate of Appropriateness
Under § 347-136(A), a certificate is required before a permit is issued, or before work begins when no permit is needed, for any of these on a covered property:
- Any improvement by addition, alteration or replacement.
- A change in exterior elevation.
- New construction of a principal or accessory structure, which includes things like a detached garage or shed.
- Any change to existing, or addition of new, signs or exterior lighting.
- Partial demolition, meaning less than substantially all of a building or facade. Total demolition has its own, stricter process.
The ordinance's definition of “permit” is broad on purpose. It includes building and demolition permits and also exterior work on fences, signs, porches, railings, steps, lighting and sidewalks, and any other work subject to public view that would alter the exterior appearance. In plain terms, if someone standing on the street or sidewalk would see the change, assume the Commission wants to see it first.
There's one important exception. Work that's part of a development application approved by the Planning Board or Zoning Board of Adjustment is exempt from a separate certificate. In that case the board refers the application to the Commission for advice instead, under § 347-142.
Work That Doesn't Need One
Section 347-136(B) is just as specific about what's exempt. No certificate is required for:
- Changes to interiors.
- Changes not visible to the public, other than relocation or demolition.
- Repair or exact replacement of an existing improvement that doesn't alter the exterior appearance. The ordinance lists these as permitted repairs:
- Identical replacement of existing windows and doors.
- Repairs to existing windows and doors, and storm doors and windows that don't change design, scale or appearance.
- Maintenance and repair of existing roofing with no change in design, scale or appearance.
- Structural repairs that don't alter the exterior appearance.
- Replacement of clapboards, shingles or other siding with identical material.
- Maintenance and repair of siding, including masonry, with no change in design, scale or appearance.
- Exterior or interior painting.
The word doing the work in that list is identical. Replacing rotted wood clapboard with matching wood clapboard is a repair. Replacing it with vinyl or fiber cement is a change in appearance and material, and that needs review. The same goes for swapping a slate roof for asphalt shingles, or wood windows with true divided lites for a different window with snap-in grids.
Emergency repairs have their own rule. Under § 347-136(C), if a covered building needs immediate work to stay habitable or safe, the emergency repair can go ahead under normal Township codes without a certificate, but only the work needed to address the emergency. You have to request Commission review at the same time the emergency work starts, and nothing beyond the emergency repair can happen until it's approved. A storm-damaged roof that needs to be dried in is the classic example.

Common Projects at a Glance
This table applies the ordinance's categories to projects Montclair homeowners ask about most. It's a planning aid, not a ruling. Planning staff or the Commission decide how your specific project is classified.
| Project | Likely path | Why |
|---|---|---|
| Repainting, any color | No certificate | Painting is exempt under § 347-136(B)(3)(g) |
| Window replacement, identical | No certificate | Identical replacement is a listed repair |
| Window replacement, new material or pattern | Certificate of Appropriateness | Change in exterior appearance; window application requirements apply |
| Storm windows that match the opening | Usually no certificate | Exempt if they don't change design, scale or appearance |
| Roof repair, same material | No certificate | Maintenance with no change in appearance |
| Roof replacement, different material | Certificate of Appropriateness | Changes material and appearance |
| Siding replaced with identical material | No certificate | Listed repair |
| Wood siding replaced with vinyl or fiber cement | Certificate of Appropriateness | Different material on a visible elevation |
| New fence, awning, exterior lighting or paving | Often a minor application | Listed minor categories if no substantial effect |
| Front porch rebuild matching the original | Ask Planning first | Porches, railings and steps are named in the permit definition; an identical rebuild may be treated as repair |
| Rear addition not visible from the street | Ask Planning first | Not-visible changes are exempt, but additions are excluded from minor review and visibility is judged from public ways |
| Detached garage or shed | Certificate of Appropriateness | New accessory structure |
| Interior kitchen or bath remodel | No certificate | Interior changes are exempt (building permits still apply) |

How the Application Works
Applications are filed with the Department of Planning & Community Development, which supports the Commission. The Township lists three application types: a full Certificate of Appropriateness application, a Minor Application, and a Total Demolition of Historic Resource application.
What every application includes
Under § 347-138(D), a complete application includes the property's zone and block/lot, applicant and owner information, the application fee and any escrow, the applicant's verification and owner's authorization signatures, photos of the existing condition of the entire facade, and close-up photos of the area of work. The ordinance text lists a $100 filing fee; confirm the current fee and any escrow with Planning before you submit. Minor applications are filed in five copies and other applications in fifteen.
Extra items by project type
- Windows: photos of each window being altered, whether you're replacing the full frame or sash only, cross-sections (head, jamb and sill) of existing and proposed windows, documentation of original windows where available, and a conditions statement describing the deterioration that justifies removal.
- Lighting: detail photos of the attachment area, manufacturer cut sheets, a photomontage, and dimensions showing projection, height and mounting.
- Facade work, additions and new construction: existing and proposed site plans, photos including adjacent buildings and the streetscape, existing elevations, working drawings, renderings, material and color specifications, and specs for any masonry repointing, cleaning, coatings or waterproofing.
Review and timing
Full applications are heard at a public meeting, and you or your representative must attend (§ 347-139(A)). The Commission meets at least monthly. It must return its written report within 45 days after referral, and if it doesn't, that's treated as a report in favor of the permit without conditions. You and the Commission can agree to more time. If it denies the certificate or attaches conditions within the 45 days, the Construction Official denies the permit or writes the conditions in. An approved certificate is good for one year unless the Commission extends it.
Minor applications go to a Minor Application Subcommittee made up of a Commission member, the Director of Planning and Community Development, and the Zoning Officer. It can approve without a public hearing. If it doesn't think the application is appropriate, it gets scheduled before the full Commission.
If you're still deciding on a design, § 347-136(D) lets you request an informal concept review. Neither side is bound by it, but it's a low-cost way to learn whether an idea is likely to fly before you pay for full drawings.
How the Commission judges a project
Section 347-137 adopts standards identical to the Secretary of the Interior's Standards for Rehabilitation. The ones that matter most for houses: repair deteriorated features rather than replacing them where possible; if replacement is needed, match the original in composition, design, color, texture and other visual qualities; clean with the gentlest means possible (sandblasting is out); and design additions so they could be removed later without destroying the building's essential form. For new work, the Commission looks at height, proportion, window pattern, materials, roof shape and scale relative to neighboring buildings.
Planning the Job With a Contractor
The Commission and the Building Office are two separate approvals. The certificate comes first; the Construction Official won't issue a permit for regulated work without it. Our building permit guide covers the permit side. To keep both moving:
- Check designation before you collect bids. A contractor who knows the property is in a district will quote the right product and build application time into the schedule.
- Ask each bidder whether the job is repair-in-kind. If it is, get the exact matching material in writing. If it isn't, ask who prepares the drawings, cut sheets and photos.
- Price the repair option, not just replacement. The standards favor repair, so a bid to restore original wood windows or patch slate gives you something the Commission is more likely to approve quickly.
- Don't let work start early. Under § 347-143, unapproved work leads to a notice with 10 days to abate by restoring the prior condition, possible injunctive relief, and daily fines on conviction that increase the longer the violation runs.
- Build the calendar backward. Monthly meetings plus a 45-day report window means a full application can add weeks to a project. Exterior jobs like painting and roofing are weather-limited, so file well before the season you want to work in.

Frequently Asked Questions
Do I need a Certificate of Appropriateness to paint my house in a Montclair historic district?
No. Montclair Code § 347-136(B) lists exterior and interior painting among the activities that do not require a Certificate of Appropriateness. That applies to color as well as repainting, since painting is listed without a color condition. Other parts of the job, such as replacing trim with a different profile, can still need review.
Can I replace my windows without going to the Historic Preservation Commission?
Only if the replacement is identical. The ordinance exempts identical replacement of existing windows and doors, repairs that don't change design, scale or appearance, and storm windows and doors that don't change design, scale or appearance. A different material, muntin pattern, size or configuration on a visible elevation is a change in exterior appearance, and the Township's window application asks for photos of each window, cross-sections of the existing and proposed units, and a conditions statement justifying removal.
What counts as a minor application?
Under § 347-128, a minor application is one that doesn't involve demolition, relocation, an addition or new construction, and is for fences, signs, awnings, lighting, paving or streetscape work that the Minor Application Subcommittee finds won't substantially affect the landmark or district, or for a field change to an existing certificate. Under § 347-136.1 the subcommittee can approve it without a public hearing; if it doesn't find the application appropriate, it goes to the full Commission.
How long does the Commission have to decide?
Section 347-139(B) says the Commission must return its written report no later than 45 days after the application is referred to it. Under § 347-139(D), failure to report within that period is deemed a report in favor of issuing the permit without conditions. The applicant and Commission can agree to extend the time. A certificate is valid for one year unless extended.
Does a National Register listing alone trigger this review?
The Certificate of Appropriateness requirement in § 347-136 applies to locally designated landmarks and properties within locally designated landmark districts. The ordinance notes that National or State Register listing isn't necessary for local designation to take effect. Separately, the demolition rules in § 347-142.1 define historic structures more broadly, including federally or state-designated districts and properties identified in the Master Plan's historic preservation element. Check your property in the Township's Historic Inventory Viewer before you plan.
What happens if work is done without a required certificate?
Under § 347-143, the administrative officer serves a notice giving the owner 10 days to abate by restoring the property to its prior condition, and can seek injunctive relief if that doesn't happen. The owner must stop work, apply for approval and, if the work is denied, restore the property. On conviction, the ordinance sets daily maximum fines that increase the longer the violation continues.
