    FAQ

    Your Questions, Answered

    What's the difference between an addition and an ADU?

    An addition expands your existing footprint - extra bedrooms, a family room, a second story - and stays connected to the main home. An ADU (Accessory Dwelling Unit) is a fully self-contained living space on your property with its own kitchen, bathroom, and private entrance. We build both, and the right choice depends on how you plan to use the space and what your lot and zoning allow.

    How long does an addition or ADU take to build?

    Most additions and ADUs take 14–30 weeks from permit approval to completion, depending on size, scope, and whether the build requires a full kitchen, bathroom, and separate utility connections. We provide a project-specific schedule before construction begins so you know exactly what to expect at each stage.

    Can I rent out my ADU?

    In most areas, yes - ADUs are a popular source of rental income. Whether a short-term or long-term rental is allowed depends on your lot's zoning and local rules. We confirm what's permitted for your specific property during the design and permitting process so your ADU is built to meet all applicable requirements from day one.

    Will the addition or ADU match my existing home?

    Yes - matching your existing home is a core part of how we design every project. We align rooflines, siding profiles, trim details, and exterior finishes so the new structure looks like it was always there. We walk you through material selections early in the design phase to lock in the right match before construction begins.

    Do you handle permits and inspections?

    Yes - permitting and inspections are handled in-house as part of our service. We prepare all drawings, submit to the appropriate jurisdiction, coordinate utility connections, and manage every required inspection. You never have to chase paperwork or follow up with the city; we keep the project moving.

    Does adding on to my home increase its resale value?

    Generally, yes. Functional additions - extra bedrooms, bathrooms, or a well-built ADU - tend to add measurable resale value and make your home more competitive in the market. The return varies by project type, neighborhood, and the overall condition of the home. We design additions to complement your property value, not just add square footage.

    Should I build out on the ground level or add a second story?

    Building out on the ground level is usually less complex and less disruptive to the existing structure, but it uses yard space and requires new foundation work. Adding a second story preserves your lot but involves structural upgrades to support the added load and temporarily impacts more of the home during construction. We assess your lot, existing structure, and goals during the design consultation to recommend the approach that makes the most sense for your project.

    Can an ADU work for multigenerational living?

    Absolutely - ADUs are one of the most practical solutions for multigenerational households. A separate entrance and self-contained layout gives aging parents or adult children genuine independence while keeping everyone close. We design ADUs specifically for long-term livability, with layouts, accessibility features, and finishes you'd want for family, not just renters.

    What Our Clients Say

    "I chose A2Z because of both the quantity and quality of their reviews for our home addition project. This project added nearly 1000 square feet between the garage, mudroom, bathroom and upstairs rooms and required pouring a foundation and tying everything into the existing home. We are very pleased with the outcome and love our new home addition."

    - Phillip S.

    "We used A to Z for a significant addition to our home, and I appreciated the up-front flat fee pricing, which was honored without question. It's rare to get a price up front and have that price honored in the construction industry, so I appreciated that and we had a good experience overall."

    - Ryan Jones

    "Excellent work! We converted our attic into a hallway with a linen closet plus an additional bedroom/closet. From start to finish our Project Manager Eliko was incredibly thorough. His crew worked efficiently and with great quality and respect for our space."

    - Hannah Henning
