How old are homes in Cedar, and what does that mean for a deck?
31% of homes in Cedar's covered ZIP code were built in 2000 or later and 4% before 1960; the largest group dates to the 1970s.
Homes in Cedar have a median construction year of 1987, so a deck original to a typical house would now be about 39 years old — beyond the point where wood framing, fasteners and flashing can be assumed sound.
Many decks from the 1970s and 1980s were built before today's detailed deck provisions appeared in model codes. Common issues on decks of this age include corroded hangers, posts set directly in soil and ledger boards fastened with nails. Replacement is often the better value than repeated repairs.
That is about the same as Anoka County overall (median 1986). Statewide, the median Minnesota home was built in 1979. Among the 62 covered Minnesota communities with Census data, Cedar ranks #28 for oldest housing. In this ZIP code, 4% of homes were built before 1960, 35% between 1960 and 1979, 30% between 1980 and 1999, and 31% since 2000 — the single largest group dates to the 1970s.

What does Cedar's climate mean for deck construction?
Cedar averages about 162 days a year at or below freezing, 63.9 inches of snow and 34.4 inches of precipitation, based on NOAA 1991–2020 normals.
The nearest NOAA climate station with 1991–2020 normals is Cedar, about 2 miles away. It records an average of 162 days a year with a low at or below 32°F — a long, hard freezing season. On roughly 85 of those days the temperature climbs back above freezing, so water in wood, soil and gaps between boards repeatedly freezes and thaws.
For Cedar, that means footings must bear below the locally required frost depth to avoid heaving, and wood surfaces should be kept sealed so absorbed water doesn't split boards over winter. Synthetic decking tolerates freeze-thaw well but still needs the manufacturer's expansion gaps.
Snow is a major factor: the Cedar station averages about 63.9 inches a year. Framing has to carry snow load, stairs need a plan for winter use, and snow removal should be done with plastic-bladed shovels and ice-melt products the decking manufacturer allows.
Precipitation averages about 34.4 inches a year, falling on about 67 days with 0.1 inch or more — wet enough that drainage and flashing still matter, but dry spells also let wood surfaces dry out and check in the sun.
Summer heat is mild by comparison — average summer highs near 79°F and only about 4 days a year at 90°F or above — so board color can be chosen mostly on looks.
Which decking material makes the most sense in Cedar?
For most Cedar homes, capped composite is the strongest starting point because about 85 freeze-thaw days a year are hard on unsealed wood and roughly 63.9 inches of snow a year means regular shoveling.
Budget, upkeep tolerance and sun exposure on your particular lot still decide the final choice between these options.
| Material | How it handles Cedar's conditions |
|---|---|
| Pressure-treated pine | Economical; needs sealing to resist freeze-thaw splitting |
| Cedar | Attractive and stable; refinish to keep its color |
| Capped composite | Low maintenance; handles moisture and freeze-thaw well |
| PVC | Lightest and most moisture-proof; premium price |
What kinds of homes are in Cedar, and how does that shape deck design?
Cedar has about 4,054 housing units across its covered ZIP code. 93% are single-family detached homes, 0% are attached homes such as townhouses and rowhouses, and about 7% are in buildings with two or more units. Roughly 96% of occupied homes are owner-occupied.
Detached single-family homes dominate in Cedar, so most decks are backyard decks attached to the rear of the house. That gives more freedom on size, layout and stairs, and makes a well-planned deck one of the most-used rooms of the home.
What deck projects are most common in Cedar?
Based on the age of Cedar's housing, the largest group of projects is likely to be replacing or rebuilding aging decks.
- Replacement and major repair: about 2,447 homes (60%) were built between 1970 and 1999, the age group whose original or early add-on decks are most likely to have worn-out framing, connectors and boards.
- Upgrades and expansions: about 474 homes (12%) were built since 2010. Their decks are usually sound but small or builder-grade, so enlarging the deck, adding stairs and switching to composite or upgraded railings are common.
- Retrofit decks on older homes: about 351 homes (9%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.
When is the best time to plan a deck project in Cedar?
With about 162 freezing days a year, the building window in Cedar is compressed. Design, drawings and permits are usually handled in winter so footings can go in as soon as the ground allows in spring, and finishes like stain are applied before nights turn cold in fall.
Do you need a permit to build a deck in Cedar?
Often, yes — especially for attached or elevated decks — but the rules are set locally. Check with the building department that serves your address: the municipality, or Anoka County for unincorporated areas.
For Cedar, MN, ask the permit office whether your deck needs a permit based on its size, height and attachment to the house, which drawings and inspections are required. Statewide code background for Minnesota is on our state page; local rules change, so the building department remains the authority.

Deck planning checklist for Cedar homeowners
- Confirm your ZIP code is 55011, the covered Cedar ZIP.
- Find out when your current deck was built and whether it uses pre-2004 treated lumber.
- Ask what footing depth your building department requires for frost.
- Plan stair location and snow storage so winter shoveling doesn't damage boards or railings.
- Probe the ledger, post bases and joist tops for soft wood before planning a resurface.
- Call 811 before any digging so utility lines are marked.
