In-Law Suites & Multigenerational Living in Chesterfield, Missouri

Chesterfield homes and this kind of project

An in-law suite in Chesterfield means working in large 1970s to 1990s two-stories and newer estate homes to the west, so on our first visit we look at zoning limits on second kitchens, the HOA indenture and which part of the house suits the person moving in.

The housing stock here: large 1970s to 1990s two-stories and ranches in established subdivisions, with newer estate homes to the west.

Walkout basements in homes of this era make the most economical suites.

Lots, exteriors and approvals in Chesterfield

Brick fronts with wood or early hardboard siding elsewhere often need siding replacement. Mature lots favor screened porches and composite decks. Subdivision trustees review exterior changes.

Subdivision lots in Chesterfield have defined building lines and easements, and HOA indentures that may be decades old but still binding. Most additions go to the rear. Matching vinyl or hardboard siding that is no longer made sometimes means re-siding a whole elevation.

What is included

For Chesterfield in-law suites we provide zoning research, design, permits, framing, plumbing, electrical, a dedicated HVAC zone or mini-split, sound insulation, an accessible bathroom, kitchenette, flooring and finishes, plus exterior entry work.

We take on in-law suite work across Chesterfield, from neighborhoods off Clarkson, Baxter and Olive to Chesterfield Valley commercial district and the Wild Horse Creek Road corridor.

What we watch for

Subdivision indentures in Chesterfield sometimes prohibit anything that resembles a second dwelling. We read them alongside the zoning code, because HOA approval is a separate hurdle from the building permit.

Chesterfield properties tend to be generous, rolling lots with mature trees, and that affects how we stage materials, where the full range of trades park and how debris leaves the site.

Permits and approvals in Chesterfield

Chesterfield's planning department together with the St. Louis County permit process is where we file for an in-law suite in Chesterfield, and the job will see zoning review plus the usual building and trade inspections.

Exterior work in Chesterfield can also involve subdivision trustees, and we put that package together for you.

Schedule and getting to you

Plan on six weeks to six months depending on the approach of site work for an in-law suite in Chesterfield, once permits and materials are in hand.

Chesterfield is down I-64 and over the Daniel Boone Bridge, just under half an hour from our Wentzville base. We plan crew days and deliveries around that drive so you get full working days on site.

What moves the price in Chesterfield

We price in-law suites & multigenerational living in Chesterfield from a site visit, not a square-foot figure. These are the items that change the number.

• A separate HVAC zone or system.
• Exterior entrance, walkway and any ramp.
