Home additions and second stories in Tarzana.
Start with the rooms your household needs: another bedroom, a larger living area or space for extended family. A ground-floor addition must connect the new structure, roof and building systems to the current house. A second-story addition also requires a design and structural review of the foundation, load paths and stair location. Those decisions belong in the scope before construction pricing.
ADUs and separate living space.
An ADU project needs a clear relationship to the main home, including access, utilities, outdoor space and construction staging. Share existing plans and the intended use of the new space. Your architect and the responsible agencies should confirm what the particular property can support; a neighborhood address alone does not establish eligibility.
When an addition becomes a whole-home remodel.
If added rooms change the circulation through the house, review the kitchen, bathrooms and common spaces at the same time. A whole-home renovation can coordinate those connected changes in one sequence. If you are considering replacing the existing house, we also review custom homes and rebuilds.
Check the Tarzana parcel and existing documents.
Los Angeles City Planning's Encino–Tarzana Community Plan information provides area context. Use the City's ZIMAS property tools to begin a parcel-specific review with your design team. The proposed work, property information and applicable review must be considered together.
Bring previous permits or drawings, site photos and any survey you have. Identify where delivery vehicles could unload and how the work would affect access to the existing home. These practical questions help define site preparation, protection and the order of construction.
Questions about expanding a Tarzana home.
Should an ADU and main-home renovation be planned together?
Review them together if they share utility work, access or site improvements. A combined plan can identify dependencies even when the construction is phased. Tell us which work is essential first and which can follow later.
What if we do not have drawings yet?
Send photos, the property location and a description of the space you need. We can discuss the construction questions and the information needed from your design professionals before preparing a defined proposal.
Start with your household's priorities.
Tell us the rooms you need, whether the house will be occupied, your design stage and an initial budget range. We will review the project fit and discuss what should be resolved next.
