When you live in the main house and rent the backyard cottage, you share a lot with your tenant. You share a yard, a driveway and often a set of trash bins. Planning for DADU tenant privacy helps both households enjoy daily life without feeling watched. It also tends to make tenants stay longer, which helps the owner too.

This guide covers entry paths, fences, landscape screens, lighting, windows, bins and shared areas. It focuses on how a tenant lives day to day rather than on family arrangements. As always, your lot, your plans and current city rules will shape what works.

Why DADU Tenant Privacy Matters

A tenant pays for a home, not a room in someone else’s yard. If they must walk past your kitchen window every time they come home, the space can feel less like their own. Over time, that friction can strain the relationship on both sides.

By contrast, a layout with clear boundaries lets each household relax. You can garden or host friends without worrying about intruding, and so can your tenant. Our guide to DADU privacy layout covers the floor plan side of this topic.

A Separate Entry Path

The route from the street to the cottage door is the first thing to plan. Ideally, it runs along a side yard rather than through the main patio. A simple paved path with its own gate gives the tenant a clear way home.

Width and surface matter too. A path wide enough for a bike, a stroller or a moving dolly makes daily life easier. A firm, slip resistant surface also helps in wet Seattle weather.

Also think about deliveries and guests. A house number or small sign at the gate helps visitors find the cottage without knocking on the main door. Meanwhile, a covered spot near the cottage entry gives packages a dry place to land.

Fences and Landscape Screens

Fences are a common way to divide space. According to the city’s fence permit page, zoning in neighborhood residential and multifamily zones generally limits fence height to 6 feet. The code also allows an additional 2 feet of architectural features such as arbors or trellises. In a front or street side setback, the limit drops to 4 feet.

Plants can soften those lines. A row of shrubs, a trellis with climbing vines or a few tall grasses can screen views without feeling like a wall. However, check plant choices and locations against any tree protection rules. Our post on Seattle DADU trees explains those rules.

Lighting That Respects Both Homes

Good lighting keeps paths safe at night. Low path lights and a fixture at the cottage door help a tenant get home without stumbling. Motion sensors can also reduce the time lights stay on. In addition, a light near the bins and the gate helps on dark winter evenings.

At the same time, bright floodlights can shine into bedroom windows. So aim fixtures down and away from both homes, and choose warm, shielded lights where possible. That way, everyone sleeps better and the yard still feels safe.

Windows and Sight Lines for DADU Tenant Privacy

Windows bring light into a small cottage, but they also create views. For DADU tenant privacy, avoid placing large windows so they look directly into the main house. Instead, angle views toward a side yard, a garden or the sky. The same thinking applies to the main house, since its windows may look down on the cottage patio.

Window height matters as well. Clerestory windows and frosted glass let light in while blocking views from the yard. Similarly, a deep porch or a small overhang can shade a door from sight lines across the lot. Your designer can show how these choices look in elevation.

Trash, Recycling and Utility Areas

Bins are easy to forget until move in day. Two households produce more garbage, recycling and compost than one. Therefore, plan a spot where both sets of bins can sit without blocking a path or sitting under a bedroom window.

A small enclosure or screened corner near the alley or street keeps bins tidy. It also makes collection day simpler, since neither household has to drag bins past the other’s door. Likewise, place meters, hose bibs and outdoor equipment where either household can reach them without walking through the other’s space.

Shared Spaces and Clear Expectations

Both homes will share some areas no matter how carefully you plan. A driveway, a side yard or a laundry room may serve both homes. In those cases, clear expectations matter as much as design.

For example, put shared rules for parking, yard use and quiet hours in the lease. Then both sides know what to expect from the first day. It also helps to agree on how you will handle guests, pets and outdoor gatherings in shared areas. If parking is part of the plan, our post on Seattle ADU parking covers the city’s rules.

Planning DADU Tenant Privacy From the Start

Privacy features are much easier to plan during design than to add later. A path, a fence line and well placed windows cost less on paper than after construction. As a result, it helps to walk the site with your designer and imagine daily routines for both households.

In the end, good outdoor design lets a tenant feel at home and lets you enjoy your own yard. Thoughtful paths, screens, lighting and shared rules can make a backyard rental work smoothly for years.
