FAQ

Questions homeowners actually ask

Short answers, tied to the Town of Castle Rock's own pages where a code figure is involved. This is not a ruling from the building department.

What is an egress window?

An egress window is an emergency escape and rescue opening large enough for a person to climb out and for a firefighter to climb in. In Castle Rock it is a building-code item for basements, not a decorating upgrade, and it is not, by itself, a bedroom approval.

Who permits work inside the Town of Castle Rock?

The Town of Castle Rock Building Division permits work at addresses inside town limits. Douglas County does not permit those in-town addresses. The Town's basement finish guide says cutting a new opening in an existing basement wall is outside that guide and requires a stamped structural plan. For new permit submittals, the Town's adopted building codes page says amendments, including the 2024 International Residential Code, took effect on June 30, 2026. A handout can lag an ordinance, so confirm the edition that applies to your submittal. This website is not the building department and cannot issue a code ruling.

What opening sizes does the Town publish?

The Town's residential basement finish guide publishes these minimums for an emergency egress window: a net clear opening of 5.7 square feet, a clear openable height of at least 24 inches, a clear openable width of at least 20 inches, and a sill no more than 44 inches above the finished floor. Where the sill is below outside grade, the guide calls for a window well of 9 square feet, with at least 36 inches of horizontal projection and width. A well deeper than 44 inches needs a permanently attached ladder or steps. The opening, and any cover, must operate from the inside without a key, tool, or special knowledge. The permit reviewer applies the code edition in force for that submittal, including Title 15 amendments.

Does the frame size on a sticker match the clear opening?

Not always. A slider opens only part of the frame, so the clear opening is smaller than the overall frame. The figures to check are the clear opening, the sill height, and the well. Those are the measurements the Town's guide names. This site does not recommend a brand or a product line.

Are Parker, Lone Tree, and Highlands Ranch under Castle Rock's rules?

No. The Town of Parker permits addresses inside Parker. The City of Lone Tree permits addresses inside Lone Tree. Highlands Ranch is not a city. The Douglas County Building Division permits the unincorporated community, and a nearby parcel can fall in another city. Castle Rock's handout does not govern those addresses. This site does not publish separate pages for those places, because a copied city page would not be a different code.

Does this website install windows, pull permits, or warranty the work?

No. Castle Rock Egress Windows is an information and referral site. It does not employ an installation crew, it does not pull permits, and it does not warranty the work. No contractor is named on this site. A call to 720-961-3434 reaches the publisher of the site on a Google Voice line, not a job site.

Will this site publish a price or a payback figure?

No. This site does not publish a Castle Rock price, a cost range, or a return on investment. A price belongs on a written quote for a specific house. An opinion of value belongs with an appraiser or an agent who has seen the property. Neither has been supplied here.

Does a basement egress opening change what a house is worth?

This site does not know that, and it will not guess. Finished area below grade is often reported separately from above-grade living area. An egress opening does not by itself rewrite an appraisal, the assessor's record, or a listing's bedroom count. Below-grade space can still be worth finishing for the household. Ask the building department about the permit, and ask an appraiser about value.

What should I ask an installer to put in writing?

Ask which building department will review the permit, who stamps the plan for a new foundation opening, how water leaves the window well, who carries the insurance, and who stands behind the workmanship. Get the company name from the company's own papers. This site has not verified a partner's license, insurance, or warranty, and it does not publish those claims.

Why are there no homeowner reviews?

This site does not publish homeowner reviews. None are shown because none have been supplied and checked. A review will not be invented to fill the page.

Is the email address working?

No. info@castlerockegresswindows.com is reserved and is not an active mailbox yet. The contact form does not send. Call 720-961-3434.
