Home Remodeling in
DuPont, WA
In much of DuPont, the city is only half the approval. Northwest Landing has its own committee that has to sign off on almost any exterior change before work starts.
Remodeling in DuPont
What building in DuPont actually involves
DuPont sits along I-5 just south of Lakewood, next to Joint Base Lewis-McChord. It began as a company town, and much of its housing now sits inside Northwest Landing, a large master-planned community with its own owners association.
That association changes how remodeling works here more than any city rule does. If your home is in Northwest Landing, the order of approvals matters, and getting it wrong can mean stopping a job halfway through.
Northwest Landing needs approval before work starts
The Northwest Landing Residential Owners Association is explicit about it. Any and all property improvements have to be submitted to its Property Improvement Committee, and its own examples include painting, replacing a roof or siding, building or replacing a fence, adding a patio cover and adding central air conditioning.
Its list of projects that need review before work begins also names decks, patios, sheds, heat pumps, solar panels, landscape renovations and adding or removing trees.
For a remodeler that covers most exterior jobs. A new deck or a roof replacement in Northwest Landing is not only a city question; the committee has to approve it first.
Two approvals, in the right order
Committee approval does not replace the city. Some projects also need a City of DuPont building permit, and the association advises getting the city building permit application before submitting a property improvement request.
The committee also enforces its own standards. Only certain paint colors and fence styles are allowed, and front yards have to keep at least half their area in grass. A design that meets the building code can still be turned down if it does not meet those.
On every Northwest Landing job we build this into the schedule, so the committee submission goes in alongside the permit rather than after it.
ADUs in DuPont
Under DuPont City Code, an accessory dwelling unit is a unit with its own living, sleeping, cooking and sanitation facilities on the same lot as a single-family home, duplex, triplex, townhome or other housing unit. ADUs are generally smaller than the main house, at 1,000 square feet or less, and can be a conversion inside the home, an addition, or a separate structure such as a converted garage.
Northwest Landing adds a layer. The association states an ADU may only be built on a single-family residential lot, and requests go to the Property Improvement Committee alongside the city permit.
One detail worth knowing before planning to rent it out: the association notes its Declaration allows it to require that all occupants of a lot be a single housekeeping unit. Talk to the association first if the plan depends on separate tenants.
City requirements on this page were last checked on 12 September 2026. Codes change, so confirm current standards with the city before you apply.

Client Reviews
What our clients say
โChris, owner of KOI build is a great guy. He personally made sure that the reconstruction of our deck was as we wanted and made sure his workers were following the things we expected. They did a great job on a hard project. All supplies and costs were explained and options given. After completion the work site was thoroughly cleaned everything hauled away. Everyone working on the project was very personable. Chris went out of his way to make sure we were happy with the results even coming over and doing painting on a Sunday to help out. This is a good company with very nice and helpful people. I would highly recommend them for any home improvement needs.โ
