Home Additions & ADUs in Lakewood, CO
A home addition or ADU can give your Lakewood property room for its next chapter. Summit coordinates new living space with the site, utilities, existing home, and any related interior improvements.
Confirm the rules for the proposal you are making
Before paying for a detailed expansion design, ask Lakewood Planning to confirm the property’s current zoning and the standards that apply to your proposed use. Older articles or saved zoning maps may not describe the rules in effect when you apply. Establish the permitted building envelope and review steps for the specific address.
Ask who supplies water and who handles wastewater
Lakewood-area service can involve independent water or sanitation districts. Identify the providers using the property’s bills and official mapping resources. Adding fixtures, changing a service, or expanding the home may prompt questions from those providers. Ask each organization about its role, requirements, and any separate charges.
Connect the remodel to the house’s existing systems
For a ranch, split-level, or home altered over time, consider how a new layout affects stairs, structure, plumbing, and heating or cooling. A kitchen or bathroom project is an opportunity to evaluate the systems serving that room. It is not a reason to assume every older system needs replacement.
Look at site conditions on the west side
Where a project approaches foothill terrain or mapped geologic constraints, use the applicable hazard maps and qualified professional advice to assess the site. Do not infer a parcel’s conditions from the neighborhood name. An addition’s drainage and foundation plan should work with the property’s actual setting.
Questions before you start
Is the City of Lakewood always my water provider?
No. Check the providers for your address. Water and sanitation approvals or charges can be separate from the city’s building review.
