680 sq ft Rental DADU
in Bothell, WA
A two-bedroom 680 sq ft DADU designed specifically for rental income in Bothell, WA. Every finish was chosen for durability, tenant appeal, and low maintenance — LVP flooring, quartz countertops, ceiling fans, and built-in closets in both bedrooms. Grey-blue fiber cement siding with a modern flat roofline and dark fascia gives it curb appeal without excessive cost. Built by Evercrest LLC for $285,000 ($419/sq ft). This detached ADU (DADU) — or backyard cottage — was designed specifically to maximize rental income.
Exterior
Grey-blue fiber cement siding with dark fascia and gutters — a contemporary color scheme that photographs well for rental listings and requires minimal maintenance.
Covered entry porch with sliding glass door. The low-profile roofline keeps construction costs down while looking modern. Landscaped yard provides separation from the main house.
Kitchen
White flat-panel cabinets with quartz countertops and stainless steel appliances — the rental trifecta of clean looks, durability, and tenant appeal.
Full-size refrigerator with water/ice dispenser, built-in oven, and cooktop. LVP (luxury vinyl plank) flooring runs throughout — waterproof, scratch-resistant, and warm underfoot. Much better for rentals than tile or hardwood.
Natural light from the kitchen window. Range hood vented to exterior.
Bedroom
Ceiling fan in each bedroom for comfort and energy efficiency. Large window with garden views. LVP flooring continues from common areas for seamless flow.
Built-in closets in both bedrooms — a must for rental units. Two bedrooms in 680 sq ft means this DADU can command significantly higher rent than a one-bedroom unit of similar size.
Bathroom
Tub/shower combo with frameless glass panel, marble-look porcelain tile surround, and rain shower head with matte black fixtures — a modern look that tenants love.
Double-sink vanity with shaker-style cabinets and quartz countertop. Framed mirror and sconce lighting. Practical luxury — looks premium, but every material is chosen for durability and easy cleaning.

Understanding Rental DADUs in Bothell
Bothell straddles King and Snohomish Counties, with regulations that allow detached ADUs (DADUs), also called backyard cottages, on most residential lots. A two-bedroom DADU like this one commands significantly higher rent than a one-bedroom — typically $2,000–$2,800/month in Bothell depending on finishes and location. With a build cost of $285,000, the rental income math works well for long-term investment. Bothell's proximity to UW Bothell, tech employers (Canyon Park corridor), and I-405 makes it a strong rental market. Evercrest LLC builds rental-optimized DADUs throughout the area.
