Residential Construction in Redwood City
Redwood City offers a diverse mix of homes, lot configurations and neighborhood conditions, which means major remodeling and expansion projects need to be planned around more than just the desired floor plan. Zoning, setbacks, lot coverage, floor area, neighborhood compatibility, existing site conditions and the age of the home can all influence the path forward.
SharrCo Builders helps Redwood City homeowners coordinate the construction process from early feasibility through permitting and final completion, whether the project involves an ADU, a major home addition or a complete home renovation.

Zoning & Development Standards
Before designing an addition or major remodel, the property's zoning and applicable development standards should be reviewed. Requirements involving setbacks, building height, lot coverage and floor area can influence what can be built and where an addition can be located.
Second-Story Additions & Remodels
Redwood City's residential development process can require Architectural Permit review for second-story additions and certain second-story remodels involving exterior modifications before the building permit process.
Larger Homes & FAR Review
Larger residential projects can require additional planning review. Redwood City currently identifies certain projects exceeding 3,000 square feet or 0.45 floor-area ratio, whichever threshold is greater, for Planning Commission review. Requirements should always be verified for the specific property and proposed scope.
Older & Pre-1940 Homes
Redwood City has additional review procedures that may apply to certain projects involving older residences. When an Architectural Permit is required, additions or demolition involving qualifying homes built before 1940 may require historic-resource review.
Planning and building requirements can change and vary by property. Project-specific requirements should always be confirmed with the City of Redwood City and the appropriate design and permitting professionals.
Redwood City Permitting & Construction Coordination
Major residential construction can involve coordination between planning, building, engineering, fire and other departments depending on the project. SharrCo Builders helps coordinate the project team and construction process so the transition from planning and permitting into construction is organized and clearly managed.
Depending on the scope, permit documents may include architectural drawings, structural plans, site information, engineering and other project-specific documentation. We work with the appropriate architects, engineers and other professionals as needed throughout the process.
Redwood City Site & Construction Considerations
Fire-Sprinkler Requirements for Larger Projects
Certain larger additions and new residential construction projects can trigger fire-sprinkler requirements. Redwood City's current residential guidance includes sprinkler requirements for qualifying new construction and certain demolition-and-addition projects reaching applicable size thresholds. The requirement should be verified for the specific project during planning and design.
Trees & Site Planning
Existing mature trees can influence the design and placement of an addition or ADU. Redwood City protects qualifying trees on private property, and certain tree removals associated with construction may require City review and permitting. Considering existing trees and other site conditions early can help identify potential conflicts before construction documents are finalized.
Building an ADU in Redwood City
An ADU can create independent living space for family, guests, a home office or other long-term needs while making better use of your existing property. Depending on the site and existing improvements, homeowners may consider detached ADUs, attached ADUs, garage conversions and other configurations.
ADUs follow a different regulatory framework from conventional home additions, so early feasibility should consider the property layout, existing structures, utilities, access, site conditions and applicable state and local requirements before the design is finalized.
Redwood City Address vs. Building Jurisdiction
A Redwood City mailing address does not always mean a property is located within incorporated Redwood City. Some surrounding residential areas are under San Mateo County jurisdiction and can follow different planning and building requirements. Confirming the correct jurisdiction is an important early step before beginning design or permitting.
SharrCo can help identify the appropriate jurisdiction as part of the early project review.

SharrCo Builders serves homeowners throughout Redwood City, including Mount Carmel, Roosevelt, Woodside Plaza, Palm Park and surrounding residential neighborhoods.

Does a second-story addition require additional planning review? +
Redwood City's current residential development guidance can require Architectural Permit review for second-story additions and certain second-story remodels involving exterior modifications. Requirements should be confirmed for the specific property and design.

Garage conversions may be possible depending on the existing structure, property conditions and applicable ADU requirements. A property-specific feasibility review is the best starting point.
Can SharrCo help coordinate design and permitting? +
Yes. SharrCo coordinates with architects, engineers and other professionals as needed and helps manage the project from early planning through construction and final inspections.
What if my Redwood City home was built before 1940? +
Certain projects involving qualifying older homes can be subject to additional historic-resource review, particularly when an Architectural Permit, addition or demolition is involved. This should be investigated early in project planning.

How long does a remodel or home addition take in Redwood City? +
Timelines depend on the design, engineering, permitting process, project complexity, material lead times, inspections and construction scope. SharrCo develops project-specific schedules rather than advertising unrealistic blanket timelines.
Does every Redwood City address use the City of Redwood City permitting process? +
No. Some properties with Redwood City mailing addresses may be located in unincorporated San Mateo County or another jurisdiction. The governing jurisdiction should be confirmed before design and permitting begin.
