Bangor, Maine, is weighing proposed ordinance changes after historic property owners raised concerns about repair costs, material choices, and delays on older homes.
The changes would affect owners who need approval before altering the exterior appearance of homes and buildings in the city’s historic districts. According to Bangor Daily News, Bangor’s historic preservation rules apply to roughly 430 properties across historic districts and sites, including nine historic districts.
The proposal is meant to make the review process clearer and more flexible for certain repairs and alterations. Local owners still say the code needs more objective standards before they can confidently price roofs, windows, trim, mechanical equipment, solar panels, and other exterior work.
Historic-home buyers outside Maine should check the same issue before committing to an old house. Local preservation rules can affect what materials are allowed, how long approval takes, whether exterior equipment can be seen from the street, and how much a repair may cost once a commission reviews it.
A Slate Roof Fight Put Repair Costs at the Center

The Bangor debate grew louder after a months-long fight over Steven Farren’s historic Broadway home. Bangor Daily News reported that Farren replaced a failing slate roof with asphalt shingles designed to mimic slate after city officials denied his request, then later received retroactive approval to keep the replacement roof.
The cost difference was the clearest part of the dispute. In a separate Bangor Daily News report, Farren cited estimates above $200,000 for a new slate roof, while the asphalt alternative cost $60,000.
The proposed ordinance changes would soften the requirement to replace certain exterior features with the exact same material when that material is unaffordable or difficult to source. For old-house owners, that can affect slate roofs, wood windows, siding, porch elements, custom trim, and specialty labor.
Rick Violette, a contractor and Broadway Historic District resident, told Bangor Daily News that the ordinance should be more objective so property owners can read it and understand what they need to do to get a permit. He also argued that appearance should matter more than material when the finished work looks historically accurate.
The Proposal Covers Materials, Equipment, Votes, and Deadlines
A Bangor city agenda summary says the proposed ordinance would update the Historic Preservation Code to add flexibility and clarity for certain alterations to historic structures. The draft also adds examples of records owners could use when arguing that strict compliance would create an undue hardship, including assessment records, tax records, and cost estimates.
The proposal also addresses modern equipment on historic buildings. Solar panels, generators, heat pumps, residential communication devices, HVAC units, and similar mechanical installations could be reviewed as minor alterations when they are visible or affect the exterior. The draft says equipment should be placed to minimize visual impact, screened where possible, located neatly, and painted when possible to reduce visibility.
The approval process could change as well. Bangor’s current historic preservation code says the commission must act within 45 days after a complete application is filed and requires four affirmative votes for a certificate of appropriateness. Under the proposal, approvals would require a majority of members present and voting, a change Bangor Daily News reported could reduce delays when attendance is low.
The timeline for approved work would expand. The current code says work must begin within six months and be completed within 12 months for certificates of appropriateness and minor alterations. The proposed ordinance would give owners 12 months to begin work and 24 months to complete it, unless the commission sets another schedule.
Historic Buyers Should Check the Rules Before Pricing Repairs
The Maine Historic Preservation Commission says local preservation ordinances are not intended to prevent changes. They are meant to guide changes so they remain sensitive to the historic structure and the surrounding community.
For buyers, a historic designation does not automatically block updates, but exterior work may need review before contractors are hired, materials are ordered, or demolition begins. Roofs, windows, porches, siding, trim, fences, solar panels, heat pumps, generators, and visible HVAC equipment can all raise questions depending on the local code.
Bangor’s proposed ordinance changes are not final. The Historic Preservation Commission is scheduled to review the changes, and city councilors may consider approval later this month. City staff also plan additional code updates this fall with more detailed guidelines for new construction and character-defining features in historic districts and sites.
Before buying or repairing a historic property, owners should ask whether the home is in a local historic district, what exterior work needs a certificate of appropriateness, what materials are acceptable, how hardship is documented, and how long approval can take.
