Local Intelligence
What San Rafael Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in San Rafael — Building Division will not accept a permit application without them. San Rafael's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
San Rafael 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 San Rafael who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $2,559/month.
Permit Process & Fees
Floor plans submitted to Building Division 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 Division ↗Construction Cost Context
San Rafael's adu / renovation construction costs run $320–$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 San Rafael
Many San Rafael neighborhoods sit in the Wildland-Urban Interface fire zone, which means your ADU plans get routed to the Fire Marshal for a separate review covering defensible space, ember-resistant vents, and sometimes a fire sprinkler requirement even if your main house doesn't have one — this can tack on several weeks beyond the standard Building Division check. Because the city sits in Seismic Zone D, older homes in the Gerstle Park and Dominican neighborhoods often need a foundation retrofit evaluation before the ADU permit gets approved, especially if you're converting a detached garage. If your lot is on one of San Rafael's many hillside streets, expect the city to also ask for a drainage and grading plan, since runoff onto neighboring properties is a common reason plans get bounced back for revisions.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 8.5-week plan check figure and the per-square-foot cost are both San Rafael-level estimates rather than numbers pulled from actual permit files, so I'd treat them as a starting point, not a promise — get a couple of local contractor bids and call the Building Division directly to check current queue times. Even without a coastal overlay complicating things here, I've seen plenty of otherwise straightforward ADU submittals stretch past 8 weeks simply because the first drawing set wasn't complete enough to clear plan check in one pass."
Market Context
San Rafael has a median home value of $1,200,000. Comparable renovation projects in this market typically add 30% to resale value.
Neighborhoods in San Rafael with the strongest renovation and resale value potential include Terra Linda, Glenwood, Peacock Gap, Dominican, Sun Valley. Highest-density single-family area with mid-century ranches and Eichlers on flat 7,500-10,000 sq ft lots, just minutes from Kaiser San Rafael Medical Center - the city's largest employer cluster.
Permit Process
Permit applications are reviewed by the Building Division, with a plan check timeline of approximately 8.5 weeks. Design review: Yes - in designated overlay zones only (Historic Districts, Hillside Development Areas, and Coastal Zone; otherwise ministerial).
San Rafael falls within Seismic Design Category D (typically D0 or D1 per ASCE 7-22), which affects structural requirements for any new addition tying into the existing structure.

Common Questions
San Rafael Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in San Rafael? +
You need accurate floor plans for: permit applications (required by San Rafael'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 San Rafael? +
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. San Rafael'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 San Rafael? +
Our floor plan drafting packages for San Rafael 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 San Rafael 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 San Rafael 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 San Rafael 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 San Rafael? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in San Rafael. 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 San Rafael? +
In San Rafael, where median home values are around $1,200,000, 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 San Rafael? +
Yes — San Rafael'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 San Rafael? +
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 San Rafael homes built before the 1990s.
