Local Intelligence
What San Bernardino 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 Bernardino — Building & Safety Division will not accept a permit application without them. San Bernardino's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
San Bernardino 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 Bernardino who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,495/month.
Permit Process & Fees
Building & Safety Division permit fees for this project type typically range from $3,500 to $12,000 depending on project valuation and scope. Plan check runs approximately 8 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Building & Safety 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 & Safety Division ↗Construction Cost Context
San Bernardino's adu / renovation construction costs run $210–$420 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 Bernardino
If your lot sits in one of the city's designated Very High Fire Hazard Severity Zones—common in the foothill areas near Highland or north Del Rosa—Building & Safety will kick your plans over to Fire Prevention for a separate review, which adds ignition-resistant construction requirements like ember-resistant vents and Class A roofing that most contractors don't price in upfront. Because San Bernardino sits in Seismic Zone D (and sometimes worse depending on your soil report), plan checkers frequently send back foundation designs for stamped calculations from a structural engineer, which can quietly add two to three weeks if your architect didn't anticipate it. On top of that, since short-term rentals aren't allowed here, some homeowners assume they can pivot to Airbnb income to offset the build cost, only to find out during final inspection sign-off that code enforcement actively checks ADU use against that rule.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 8-week plan check timeline and $300/sqft figure are San Bernardino state-level estimates rather than verified local numbers, and I've seen actual plan check queues run considerably longer plus contractor bids swing well above that per-square-foot figure depending on finishes and site conditions — get local quotes and call the Building & Safety Division directly before you bank on either number."
Market Context
San Bernardino has a median home value of $362,000. Comparable renovation projects in this market typically add 25.0% to resale value.
Neighborhoods in San Bernardino with the strongest renovation and resale value potential include Verdemont, Ridgeline, Arrowhead Farms, North Park, Kendall. Very large lots and higher home values make Verdemont ideal for detached ADUs and rentable units.
Permit Process
Permit applications are reviewed by the Building & Safety Division, with a plan check timeline of approximately 8 weeks. Permit fees in San Bernardino range from $3,500 to $12,000 depending on project scope.
San Bernardino falls within Seismic Design Category D (site-dependent; may be E or F), which affects structural requirements for any new addition tying into the existing structure.

Common Questions
San Bernardino Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in San Bernardino? +
You need accurate floor plans for: permit applications (required by San Bernardino'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 Bernardino? +
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 Bernardino'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 Bernardino? +
Our floor plan drafting packages for San Bernardino start at $997 for a standard residential home. This includes 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 the same work. We deliver within 10 business days with a 14-day money-back guarantee.
How do you create floor plans remotely for my San Bernardino 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 Bernardino 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 Bernardino 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 Bernardino? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in San Bernardino. 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 Bernardino? +
In San Bernardino, where median home values are around $362,000, 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 Bernardino? +
Yes — San Bernardino'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 Bernardino? +
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 Bernardino homes built before the 1990s.
