Window work in Lakewood

Lakewood's incorporated housing stock is a postwar suburb with a 1977 median, not a prewar grid. The practical window question is which decade the opening belongs to, because a 1950s single-glazed frame and a 1980s vinyl unit fail in different ways.

Housing age in the census

Source: U.S. Census Bureau, table B25034 and table B25035, Lakewood city, Colorado. The Census Bureau does not record window frame material.

The three largest decades are the 1970s (15,887 units, 21.6%), the 1960s (13,300, 18.1%), and the 1980s (11,703, 15.9%). The 1950s still hold 8,256 units (11.2%). Houses from 1939 or earlier are 1,964 units, 2.7% of the city. A bid that treats every Lakewood opening as a mid-century steel casement is describing a slice of the stock, not the median house.

Climate at the Lakewood station

NOAA's 1991 to 2020 climate normals for the station named LAKEWOOD, CO US (USC00054762) put the instruments at 1,719.1 meters, about 5,640 feet. The annual average temperature is 51.4 F. The normal daily maximum is 66.2 F and the normal daily minimum is 36.5 F. Annual precipitation is 17.32 inches and annual snowfall is 55.8 inches. The normal daily temperature range is 29.7 F, so a seal sees a wide swing on an ordinary day, before any storm.

Hail and wind in the NOAA storm file

In the NOAA storm events detail files for 2015 through 2024, the place name Lakewood is on 11 hail reports. The largest of those is 2.00 inches on 8 May 2017. Jefferson County, which contains Lakewood, has 152 hail reports in the same years. The county maximum is 2.75 inches at Edgewater on that same May date. Edgewater is not Lakewood. The county total is the wider exposure, and it includes other cities.

Thunderstorm wind reports with the place name Lakewood number 2. The larger is a measured gust of 56 knots, about 64 mph, on 6 June 2020. Jefferson County has 15 thunderstorm wind reports, and the largest is 68 knots, about 78 mph, at Columbine on 6 June 2020. Gusts in this NOAA file are stored in knots.

High wind is logged by forecast zone rather than by city. The zone named "Boulder and Jefferson counties below 6,000 feet / west Broomfield County" has 27 high wind events in those ten years. The largest measured gust in that zone is 94 knots, about 108 mph, on 30 December 2021. Lakewood sits in the plains portion of Jefferson County, so that zone is the relevant wind record. It is a zone total, not a sensor in one yard.

Permits in Lakewood

Lakewood's adopted residential code, chapter 14.09, lists work that does not need a building permit. One exemption is "Shutters, windows, gutters, door, and other minor cosmetic additions not affecting the structure." The same section says an exemption is not permission to violate the code. If the work changes structure, it is outside that sentence. The existing-building appendix in that chapter says replacement windows shall comply with the 2021 International Energy Conservation Code as adopted in chapter 14.08.

The city's egress window handout covers a new or altered basement opening. It calls for a structural design when the foundation is cut, a clear opening of at least 5.7 square feet, a width of at least 20 inches, a height of at least 24 inches, and a sill no more than 44 inches above the floor. Permits for city addresses go through eTRAKiT, and contractors must be registered with Lakewood. The permit counter covers the city. Confirm the address is inside city limits before you assume this office is the one that inspects.

This page is a reading of those posted rules. It is not a permit determination.

Do I need a permit to replace windows in Lakewood?

Work that cuts or changes structure is outside that exemption. The same chapter says replacement windows shall comply with the 2021 International Energy Conservation Code as adopted in chapter 14.08. A new or altered basement egress opening is covered by the city's egress handout and needs a structural design. Confirm the address is inside city limits.
