Windows In Fairhaven’s Historic District: What’s Allowed

Thinking about updating your windows in Fairhaven’s Historic District and not sure what’s allowed? You are not alone. You want comfort and energy savings, but you also need to protect your home’s historic character and follow the city’s review process. In this guide, you’ll learn which window changes usually get approved, which ones do not, how to boost efficiency without losing charm, and how to navigate the local review with less stress. Let’s dive in.

What rules apply in Fairhaven

Fairhaven is a locally designated historic district, and the City of Bellingham’s Historic Preservation Program reviews exterior changes that are visible from the public right of way. Window work seen from the street almost always needs approval before you start.

Start by reviewing the Fairhaven Historic District design guidelines and the city’s historic preservation procedures. Decisions typically align with the Secretary of the Interior’s Standards for Rehabilitation, along with guidance from the National Park Service and Washington State DAHP. A quick pre-application call with staff can save time and prevent denied permits.

Common triggers for review include replacing windows, altering sizes or locations of openings, changing materials or muntin patterns, and adding exterior storm windows. Rear or less visible elevations may have more flexibility, but you still need to confirm scope with staff.

Repair vs. replacement: what reviewers prefer

Start with repair in place

Repairing original wood windows is the preferred path. You keep the historic sash, frames and trim, and address issues like rot, glazing, hardware, and weatherstripping. Techniques like epoxy consolidation and Dutchman splices often bring windows back to good condition. This preserves original profiles, sightlines and character.

Pairing repairs with storm windows or interior secondary glazing boosts energy performance while keeping the appearance intact. Reviewers favor this approach because it preserves historic material and is reversible.

Add storms or interior secondary glazing

Storm windows are a highly recommended upgrade. Options include:

• Painted exterior aluminum storms that fit within trim lines
• Wood storms painted to match visible trim
• Interior removable panels for minimal visual change
• Low-e storm sash or interior panels for added efficiency

Because the original window stays, storms are usually considered compatible and reversible. When properly fitted, storms can deliver comfort and energy savings close to replacement windows while preserving your home’s look.

When in-kind replacement is allowed

If repair is not feasible, in-kind replacement can be approved. You will need to document deterioration and explain why repair will not work. Approved replacements usually match the original in material, profile, muntin pattern, proportions, finish and operation. On primary facades, wood is generally preferred, and historic trim should be preserved or reinstalled.

Expect to submit photos, condition assessments, and product details. Reviewers look for a close visual match from the street.

Compatible modern replacements, case by case

Modern units like wood-clad or fiberglass can be considered if they closely match wood profiles, sightlines and divisions. Vinyl on street-facing elevations is commonly discouraged because of profile and texture differences. Non-wood products may be more acceptable on rear or non-contributing elevations, but it is case by case.

Opening changes and full-frame swaps

Altering historic openings by enlarging or moving them is typically not allowed on primary elevations. Full-frame replacements that change opening proportions or cover trim face heavy scrutiny. If you pursue these options, expect to provide strong justification and detailed design to replicate original dimensions.

Energy upgrades that preserve character

Low-impact upgrades with high acceptance

• Weatherstripping and sash sealing to reduce drafts
• Repairing glazing and restoring smooth sash operation
• Exterior or interior storm windows for a big comfort boost
• Insulating shades or removable interior panels

These measures are reversible and often recommended first.

Moderate upgrades to consider

• Interior secondary glazing units that are removable and fit within existing casing
• Interior-applied low-e films that do not damage historic glass
• Restored sash weights or balance systems for a tighter fit

These may require review, but are often acceptable when reversible.

What to avoid on public-facing sides

• Dark tint or highly reflective glass that changes street view
• Exterior insulated units that add bulk or cover trim
• Full-frame vinyl replacements on primary elevations

If you explore double-glazed replacement units, reviewers will expect historic sightlines and appropriate muntin profiles, such as true-divided light or simulated divided light with accurate details.

Performance expectations

Repairing original windows and adding storms can deliver significant energy savings and improved comfort. For many Fairhaven homes with single-pane windows, a combined strategy of repair, weatherstripping and storm windows provides a strong cost-benefit while meeting preservation standards.

How to navigate Bellingham’s review

Step-by-step process

1. Schedule a pre-application consult with Historic Preservation staff.
2. Prepare and submit a Certificate of Appropriateness application with photos, drawings and product data.
3. Participate in staff or board review, depending on scope.
4. Receive approval and conditions, then pursue any separate building permits if required.

What to include in your application

• Clear photos of each window and full elevations
• Sketches or measured drawings of existing profiles and muntins
• A brief condition assessment with evidence of deterioration
• Contractor or specialist reports if claiming repair is infeasible
• A detailed scope describing repair methods or in-kind replication
• Product sheets and finish samples for storms or replacements
• A simple visual mockup showing the street view after the work
• A short checklist showing how your proposal meets the Secretary’s Standards

Typical approval conditions

• Match existing visible profiles and muntin patterns
• Use painted finishes on street-facing elevations
• Provide a sample window or corner mock-up for final sign-off
• Install storm windows with reversible fasteners that protect historic fabric

Timeframes and budgeting

Historic review can add several weeks to a couple of months, depending on scope and schedules. Pre-application conversations help shorten timelines. Repair-first strategies can cost less than wholesale replacement, while high-quality in-kind wood windows cost more but deliver better longevity and preservation outcomes. If you are unsure about scope, budget for a specialist assessment.

Smart contractor and product choices

Choose pros with historic window experience

Hire contractors or glaziers who have repaired historic windows in regulated districts. Ask for similar project references. General window vendors may push full replacement by default, so look for preservation-minded teams.

What to look for in storms

Choose storms with narrow sightlines, baked-enamel painted finishes and hardware that does not damage trim. Paint to match surrounding trim, and make sure the fit aligns with existing lines.

Replacement window tips

If replacement is approved, insist on samples or a small mock-up before placing a full order. Match operation type, muntin patterns, profiles and proportions. On primary facades, wood is typically preferred, with historic trim preserved or replicated.

Make your plan

• Assess your existing windows for repair potential.
• Talk with Historic Preservation staff early to confirm what is likely to be approved.
• Choose a repair-first path with storms for the best preservation and energy results.
• If replacement is needed, document why and match historic details closely.
• Prepare a complete application package to streamline approval.

Are there incentives to help with costs?

• Federal rehabilitation tax credits focus on income-producing historic buildings, not most private homes. Local or state incentives can vary, so check with the City of Bellingham and Whatcom County programs or state-level energy resources.
