Local Intelligence
What San Ramon 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 Ramon — Building and Safety will not accept a permit application without them. San Ramon's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
San Ramon 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 Ramon who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $2,437/month.
Permit Process & Fees
Building and Safety permit fees for this project type typically range from $8,000 to $18,000 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 and Safety 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 and Safety ↗Construction Cost Context
San Ramon'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 San Ramon
If your property is in the San Ramon Valley Unified School District, expect to pay $5.17 per square foot in school impact fees, which can significantly drive up total permit costs for larger ADUs. Additionally, many neighborhoods governed by HOAs in San Ramon require pre-approval of ADU designs, and their guidelines often exceed city requirements, adding weeks or even months to your project timeline. For properties on slopes or near ridgelines, a site-specific geotechnical report may be required due to San Ramon's hillside development restrictions, adding both cost and time.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 8-week timeline and the per-square-foot cost figure are really just statewide estimates dressed up as San Ramon-specific numbers, so I always tell clients to get two or three local contractor quotes and call Building and Safety directly before penciling in a schedule; with 75% of the area under HOA control, don't be surprised if your architectural review adds its own timeline on top of whatever the city quotes you."
Market Context
San Ramon has a median home value of $1,500,000. Comparable renovation projects in this market typically add 28% to resale value.
Neighborhoods in San Ramon with the strongest renovation and resale value potential include West San Ramon Hills, Bent Creek / The Hills, Bollinger Hills, Old Ranch Estates & Summit, Norris Canyon Estates & Roubion. Established hillside single-family neighborhood with quarter- to half-acre lots near Bishop Ranch — ideal lot sizes for detached ADUs and strong job-driven rental demand.
Permit Process
Permit applications are reviewed by the Building and Safety, with a plan check timeline of approximately 8 weeks. Permit fees in San Ramon range from $8,000 to $18,000 depending on project scope.
San Ramon falls within Seismic Design Category D0 / D1 / D2 / E (site specific), which affects structural requirements for any new addition tying into the existing structure.

Common Questions
San Ramon Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in San Ramon? +
You need accurate floor plans for: permit applications (required by San Ramon'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 Ramon? +
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 Ramon'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 Ramon? +
Our floor plan drafting packages for San Ramon 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 Ramon 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 Ramon 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 Ramon 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 Ramon? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in San Ramon. 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 Ramon? +
In San Ramon, where median home values are around $1,500,000, 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 Ramon? +
Yes — San Ramon'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 Ramon? +
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 Ramon homes built before the 1990s.
