Beach house soul. Gorgeous Sound views. A bigger vision. In Old Town Mukilteo, 506 4th Street brings together the charm of an eclectic beach house and the opportunity to create something extraordinary. Reimagine the existing home with a thoughtful remodel, then bring the bigger picture to life with plans for two detached accessory dwelling units. Architectural and civil plans are available, with both DADU permits reported by the City as ready to issue. Create a multigenerational retreat with separate homes for privacy and space to come together, live in one home and pursue rental income from the others, or develop a long-term investment in a location people love. Picture morning coffee overlooking Puget Sound, afternoons at nearby Lighthouse Park, dinner along the waterfront, and ferry trips to Whidbey Island. The character is here. The views are here. The next chapter is yours to create. Buyer to verify current permit status, remaining fees, approval conditions, and intended uses. Buyer to verify all to own satisfaction.
