Duplex & Multifamily Builder in Rainier, WA

It depends on your city's zoning, but the answer is yes more often than it used to be. Many Washington cities now allow duplexes, townhomes and other middle housing on lots that were once limited to a single house. Greg checks the zoning, setbacks and utility capacity for your lot before you commit to a design.

Sometimes. Rural zones are usually stricter than cities, and the septic and well capacity of the land matter as much as the zoning. Greg checks what your county allows and what the site can support, so you know whether a duplex or another option fits your property.

Moisture control. Rentals get less day-to-day attention than owner-occupied homes, so Greg builds in what keeps them healthy without relying on tenants: strong bath and kitchen ventilation, durable siding and flashing details, gutters and drainage that carry water away, and a well-vented crawl space or a properly prepared slab.

It depends on the number and size of units, the lot and site work, utility connection fees, the finish level and the design. Building two units on one foundation under one roof usually costs less per unit than two separate houses, which is a big part of the appeal. Greg's estimates are free and broken down so you can run your own numbers.

With the whole wall and floor assembly, not just insulation. Greg uses separated or staggered stud walls, sound insulation and sealed penetrations at the shared wall, along with layouts that keep bedrooms away from it where possible. Quieter units mean happier tenants and longer leases.
