Home additions & new homes in Redwood City.
A better connection between rooms, more space for family or a home planned from the ground up. Sami & Sons serves Redwood City homeowners with a construction conversation built around the property, the design and the decisions that matter to you.

Give the existing home a proper starting point.
Before changing the building, understand its records and its place on the site. Existing approvals, historical questions and the proposed exterior form can influence how the project moves from an idea to construction drawings.
Use the City’s single-family resources.
Redwood City brings architectural permits, neighbor notification, historic resources and tree permits together on its single-family housing page. Review those topics with your designer and ask Planning which are relevant to the actual proposal.
Read the city guidanceDescribe what will remain and what will change.
The City’s architectural-permit guidance asks homeowners to consider design-review findings and whether a property has historical significance. Existing photographs and clear demolition and proposed plans help make that discussion specific.
Read the city guidanceKeep the scope tied to the latest drawings.
An extra level, a revised roof or a larger opening to the garden can affect more than the room being added. Bring the latest plan set and city comments into our conversation so we can discuss the connections to the existing structure and the selections still to resolve.

- A list of unresolved decisions about layout, exterior materials and access
Before we talk.
Should we check historical questions before planning a major change?
Yes. Redwood City’s single-family resources include historic-preservation information, and its architectural-permit guide raises that question early. Ask Planning how it relates to your property before making assumptions about removal or replacement.
Does a Redwood City mailing address settle the permit jurisdiction?
Confirm the parcel’s jurisdiction at the outset. Share the full address and any existing permit records so the project team can identify the correct reviewing authority.
Can you talk through a new home and an addition as separate options?
Yes. Describe your priorities and what you value about the current home. The two options need their own scopes, assumptions and design information to make the comparison meaningful.
Local planning resources.
City guidance checked September 18, 2026. The applicable requirements depend on your property and proposal; confirm them with the City and your design team.
