Choosing Exterior House Colors in Portland

In most of Portland you can paint your house any color you like. The city's zoning code treats repainting an already painted surface as maintenance, which is exempt from historic review even in historic districts. The limits that come up more often are an HOA's recorded rules, your siding maker's heat limits on dark colors, and how a color looks under a gray sky.

This guide does not pick colors for you. It covers the parts of the decision you can check: what Portland, Vancouver and Oregon law actually say, what light reflectance value means for siding and trim, and how to test samples in local light before a painter orders forty gallons.

Does Portland regulate exterior paint colors?

Only through the historic resource overlay, and even there a color change on painted siding is normally exempt. Portland's Zoning Code chapter 33.445 (the version posted on portland.gov, dated October 1, 2024) lists the proposals that need historic resource review and the ones that are exempt. “Maintenance” is on the exempt list for Historic and Conservation Landmarks and Districts (National Register resources need no historic resource review for development at all), and the code's definitions chapter (33.910, dated July 1, 2026) gives painting a previously painted surface as its first example of maintenance. Painting something that has never been painted is different:

Source: Portland Zoning Code 33.445.100 to 33.445.220 (10/1/24) and 33.910 (7/1/26). This summarizes the code for painting only. Demolition, additions and other alterations follow separate rules.

Two cautions. First, the maintenance definition does not mention color at all; on our reading, a new color on already painted siding still counts as painting a previously painted surface. If your house is an individual landmark whose designation documents list its colors, confirm that with the city before you buy paint. Second, painting brick or stone that has never been painted is the change the code singles out, and it is also the hardest to undo: our guide to painting a brick fireplace explains why the Brick Industry Association treats painted brick as close to permanent.

Portland's design overlay zone (33.420), which reviews the look of development in some parts of the city, exempts work that needs no permit, repair and maintenance, and sites used only for household living with four or fewer homes outside the RX, EX and CX zones, as long as any new building or addition stays within 35 feet. To find out whether your house is a landmark or in a district, Portland Permitting & Development points to its historic district maps and PortlandMaps, and offers a free 15-minute appointment with a city planner.

What about Vancouver and the rest of the metro?

In Clark County the review track is different. Clark County's certificate of appropriateness page says a property on the Clark County Heritage Register or within a historic district or overlay needs a certificate before alterations begin, with staff handling small like-for-like work and the Historic Preservation Commission hearing proposals that change a building's appearance. Ordinary repair and maintenance generally do not need a certificate from the commission, but the page says they still require an administrative staff review, and it does not mention painting either way. If your Vancouver house is on the register or in an overlay, call the county's historic preservation staff before you pick colors.

Other metro cities with designated historic resources set their own rules, and we have not read each one. Ask that city's planning department, and get the answer in writing if a color change is part of the plan.

Can your HOA tell you what color to paint your house?

Yes, if its recorded documents say so, and in Oregon that is built into the law. The Oregon Planned Community Act, ORS 94.550 to 94.783, requires a planned community's declaration to state any provisions restricting what owners can do with their lots, and ORS 94.580 names architectural controls, including the choice of exterior colors and materials, and review of building plans, as examples. Condominiums fall under a separate chapter, ORS chapter 100.

In practice that means three documents to read before choosing a color:

1. The declaration (CC&Rs), recorded with the county, which says whether architectural control exists and who exercises it.
2. Design guidelines or an approved color list, if the board or an architectural review committee has adopted one.
3. The approval process: what to submit (for example, the color names and numbers for body, trim and door), who decides, and how long it takes.

Get approval in writing before the painter starts. A painter can apply whatever you choose; only the association can say it complies. Vancouver HOAs work under Washington law, but the same reading list applies: the recorded declaration and any adopted guidelines are where color rules live.

What is light reflectance value (LRV), and why does it matter outside?

Light reflectance value is the percentage of light a color reflects, on a scale where, in Benjamin Moore's definition, 100 is pure white and 0 is absolute black. Benjamin Moore lists it on each color's web page; its White Dove, for example, is listed at 83.16. The lower the number, the more sunlight the color absorbs as heat.

Heat is the cost of a dark house. The USDA Forest Products Laboratory's Wood Handbook says darker finishes cause more solar heating, and with it more warping and checking of wood siding than light finishes. It adds that dark colors are more prone to moisture blisters because they get hotter in the sun, that many dark finishes fade to an unacceptable look long before they fail, and that white is always a safe choice. None of that rules out a dark or colorful house, but it changes where the color goes. The south and west walls take the most sun, and our guide to how long exterior paint lasts in Portland explains why those walls wear out first.

Which colors are safe on vinyl siding and PVC trim?

This is where LRV stops being a design term and becomes a written limit. Vinyl and PVC soften with heat, and the makers set floors:

The thresholds differ by a point or two, so the rule that matters is the one written for your siding and your paint. Before you fall for a deep color on a vinyl-sided house, find the color's LRV and check it against both documents. A painter should do the same, and a quote that names the product line and the vinyl-safe color is easier to hold to.

How should you test paint samples in Portland light?

Benjamin Moore's exterior color guide gives the method: brush its sample paint onto a white foam board rather than the house, since the samples are interior formulas, then take the board outside and watch it through the day. A color in a tree's shade reads darker than the same color in direct sun, and the direction a wall faces changes how it looks.

Portland adds a local twist: most days are gray. NOAA's Comparative Climatic Data for Portland International Airport averages about 222 cloudy days a year, against 68 clear and 74 partly cloudy, and December averages about 26 cloudy days. Its older sunshine record (1965 to 1983) shows Portland getting 20 percent of the possible sunshine in December and 72 percent in July. A color picked on a bright August afternoon will spend most of the year under overcast light.

• Look on a cloudy day and a sunny one, and in the morning and late afternoon.
• Hold the boards against each side of the house, because the north wall and the sunny south and west walls will not look like the same color.
• Stand where people see the house, from the street and the sidewalk, not just up close.
• Judge body, trim and door together. Benjamin Moore says homeowners typically use three to four colors in an exterior scheme.

Start with what you are not repainting

Benjamin Moore's guide tells homeowners to begin with the elements that will not change, such as roofing, stone, brick and landscaping, and to pull colors from them. On many Portland houses that list includes the roof, any brick chimney or foundation, the windows and the front steps. A body color that fights the roof will keep fighting it for the life of the paint job, so hold the sample boards next to those surfaces as well as against the siding.

Two practical limits come with a color change. Benjamin Moore's Aura Exterior sheet notes that certain custom colors need a deep-color primer tinted to a special formula to reach the intended shade, which is an extra coat to price in. And on a house built before 1978, any scraping and sanding before the new color goes on falls under lead-safe rules, which our guide to painting a pre-1978 home explains.

Which sheen should siding, trim and doors get?

Sheen changes how a color looks on the wall, so choose the two together. Exterior lines are sold in several sheens, and the data sheet for each says which; Rodda's Protector XL-100, for example, comes in flat, velvet and satin. Judge the color in the sheen you will actually use, sampled in that sheen if you can. Our guide to paint sheens explains the differences between flat, eggshell, satin and gloss.

Local paint makers and color collections

Two of the brands on Portland paint-store shelves are local, which is useful mostly because their stores and color collections are here:

• Miller Paint. Its company page says it was founded in Portland in 1890, has manufactured paint in Portland since then, became employee-owned in the 1990s, and has more than 50 stores in Oregon, Washington and Idaho. It publishes a Northwest Color Collection that it describes as rooted in the region.
• Rodda Paint. Its company page dates the business to 1932 and lists more than 130 retail locations across the Northwest, and its data sheets say its paint is formulated and manufactured in Portland. Its website now presents the brand as Rodda-Miller Paint.

Paint makers also publish color forecasts. Sherwin-Williams' 2027 Color of the Year is Celery SW 6421, which it describes as a soft, muted green. That is the maker's own forecast; its page does not suggest the color for exteriors, and a forecast says nothing about how a color holds up on a south wall. Test any trend color the same way as any other.

To describe a project, use the project request form. Whoever you hire, check the license first: an active Oregon CCB license, plus the CCB's Lead-Based Paint Renovation license on a house built before 1978, or a Washington L&I contractor registration in Vancouver and Clark County. Our guide to checking a painter's license shows how, and our exterior house painting page covers what the job involves.
