Common Uses in Redwood City
Local Intelligence
What Redwood City Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Redwood City — Building & Code Enforcement Services will not accept a permit application without them. Redwood City's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Redwood City does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
Homeowners in Redwood City who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $3,495/month.
Permit Process & Fees
Building & Code Enforcement Services permit fees for this project type typically range from $7,000 to $11,000 depending on project valuation and scope. Plan check runs approximately 12 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Building & Code Enforcement Services as part of a permit application must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus if structural changes are involved, a licensed engineer must stamp the structural drawings.
Visit Building & Code Enforcement Services ↗Construction Cost Context
Redwood City's adu / renovation construction costs run $250–$490 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Redwood City
If your ADU is 750 sqft or larger, Redwood City applies development impact fees, which include school district fees from Sequoia Union High School District—this can add several thousand dollars to your project costs unexpectedly. Additionally, homeowners in areas with older sewer infrastructure often face mandatory lateral upgrades, which can run $10,000–$15,000 and require coordination with Public Works before permits are approved.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Redwood City submittals, that 12-week plan check figure and the $/sqft cost number are really state-level estimates, not local truth — I'd get quotes from at least two Peninsula-based contractors and call Building & Code Enforcement Services directly before you bank on either one holding up. Also worth noting: with HOA presence at 30%, don't be surprised if a CC&R review adds its own delay on top of whatever the city hands back."
Market Context
Redwood City has a median home value of $1,550,000. Comparable renovation projects in this market typically add 30% to resale value.
Neighborhoods in Redwood City with the strongest renovation and resale value potential include Farm Hill, Edgewood Park, Mount Carmel, Woodside Plaza, Eagle Hill. Top ADU pick with large 7,000-12,000 sq ft lots, detached single-family housing stock, and strong $2,800-$3,500/mo rental demand near downtown employers.
Permit Process
Permit applications are reviewed by the Building & Code Enforcement Services, with a plan check timeline of approximately 12 weeks. Permit fees in Redwood City range from $7,000 to $11,000 depending on project scope.

Common Questions
Redwood City Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Redwood City? +
You need accurate floor plans for: permit applications (required by Redwood City's building department for any structural work), refinancing or home equity loans, selling your home (accurate square footage documentation), renovation contractor bidding, HOA design review submissions, and insurance claims. Our as-built drawings capture your home's exact current dimensions.
What is an as-built floor plan and why do I need one in Redwood City? +
An as-built floor plan documents your home as it currently exists — including all room dimensions, door and window locations, wall thicknesses, and square footage. These are required when the original permit drawings are unavailable or the home was modified without permits. Redwood City's building department requires accurate as-builts when you apply for renovation or addition permits on older homes.
How much does floor plan drafting cost in Redwood City? +
Our floor plan drafting packages for Redwood City cover measured floor plans for all levels, room labels, door and window schedules, and verified square footage. Local drafting services typically charge $1,500–$4,000 for comparable work. Contact us for current pricing and to discuss your project. 14-day money-back guarantee.
How do you create floor plans remotely for my Redwood City home? +
You provide basic measurements (room dimensions, door/window sizes) and photos of each room. Our drafting team converts these into accurate CAD drawings with precise dimensions, wall thicknesses, and notations. For permit-grade as-built drawings, we may request additional measurements or a site visit from a local partner. We serve all Redwood City neighborhoods remotely.
What format are the floor plan drawings delivered in? +
We deliver drawings in PDF (for printing and permit submission) and DWG/DXF (AutoCAD-compatible format for contractors, engineers, and architects to work from). All drawings are formatted to Redwood City building department standards and include title block, scale, and code notations required for permit submission.
Can you draft floor plans for a rental property or multi-unit building in Redwood City? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Redwood City. Multi-unit buildings are priced based on the total number of units and floors. Contact us for a custom quote if your property has more than 4 units.
Will accurate floor plans increase my home's value in Redwood City? +
In Redwood City, where median home values are around $1,550,000, inaccurate or missing square footage records can suppress list price and appraisal value. Professional as-built drawings establish defensible square footage for appraisers and buyers. Unpermitted additions documented and legitimized through permit drawings can recover thousands in appraised value.
Do I need floor plans to get an ADU or addition permit in Redwood City? +
Yes — Redwood City's building department requires accurate floor plans as part of any ADU, garage conversion, or addition permit application. Our packages combine floor plan drafting with the full permit-ready drawing set (site plan, elevations, electrical, Title 24) needed for plan check submittal. If you only need the floor plans themselves, our Starter package covers that.
Can you draft floor plans from old blueprints or photos in Redwood City? +
Yes — we can redraft from original blueprints, scans of old permit sets, hand-drawn sketches, or room photos combined with your measurements. We regularize old drawings to current CAD standards and update them to reflect any modifications made since original construction. This is a common service for Redwood City homes built before the 1990s.
