How Does San Diego Calculate Your Remodel’s Permit “Valuation”? (2026)
San Diego doesn’t base certain permit fees on what you’re paying your contractor. It uses a published per-square-foot schedule instead, and the two numbers can be very different.

Key takeaways
- Your permit “valuation” is not your contract price. San Diego uses a published per-square-foot schedule (Information Bulletin 101) to set an official construction valuation, separate from what you’re actually paying your contractor.
- Most single-family remodels and additions are valued as occupancy Group R-3, with the exact rate depending on the home’s construction type.
- Two state fees are calculated directly from this valuation number: the State Seismic Fee and the State Building Standards Fee, both set as a rate per dollar of valuation.
- Work that adds no new floor area — closing a wall opening, adding a window, an interior partition — uses a separate, smaller valuation table.
- Partial permits (foundation only, structural frame only, shell only) are valued as a set percentage of the full project’s valuation.
- The schedule’s per-square-foot figures are sourced from industry construction-cost data that is updated on its own schedule, so it can lag what materials and labor actually cost in a given year.

What “valuation” actually means
When you apply for a building permit in San Diego, the city assigns your project an official “construction valuation.” Information Bulletin 101 describes this as a schedule of “average construction costs” used to value new construction, additions, alterations, and other building work. It is a published, per-square-foot figure pulled from a standard table — not an estimate based on your signed contract, your material selections, or your contractor’s bid.
That distinction matters because homeowners often assume a bigger number on a permit document means a bigger bill from their builder. It doesn’t. The valuation is an administrative figure the city uses for its own calculations, and in a market like San Diego’s, it can run well below or above what a project actually costs to build, depending on scope and finish level.
Why your project is “Group R-3”
San Diego’s valuation schedule is organized by occupancy group, which is a building-code classification for how a structure is used, and by construction type, which describes what the building is made of (wood frame, masonry, steel, and so on). For a typical single-family home — a kitchen expansion, a primary suite addition, or a full interior remodel — the applicable occupancy group is R-3: Residential, one- and two-family.
Multi-family buildings use a different row (R-2), and a detached garage is valued separately under the “Utility, miscellaneous” classification. If your project changes how a space is used — turning a garage into living space, for example — Information Bulletin 101 instructs applicants to value the change as the difference between the old use’s rate and the new use’s rate, not the full new-use rate on its own.
Construction type changes the rate
Within Group R-3, the per-square-foot rate still depends on construction type. San Diego’s schedule lists nine types, running from fire-resistive Type I construction down to standard wood-frame Type V construction, which covers most single-family homes in the county. The table below shows the full R-3 range.
| Construction type | Valuation rate |
|---|---|
| Type I-A | $209.61 / sq ft |
| Type I-B | $203.74 / sq ft |
| Type II-A | $198.94 / sq ft |
| Type II-B | $195.12 / sq ft |
| Type III-A | $188.41 / sq ft |
| Type III-B | $181.45 / sq ft |
| Type IV | $191.77 / sq ft |
| Type V-A | $175.86 / sq ft |
| Type V-B (standard wood frame) | $165.67 / sq ft |
Most ground-up single-family construction and additions in San Diego County are built as Type V-B, standard wood frame. Your plan set — not a guess from a photo or a general assumption — is what determines which row actually applies to your project, so confirm the construction type with your designer or the plan checker before you rely on any figure here.
Patio covers, pools, and other add-ons
Beyond the main per-square-foot table, Information Bulletin 101 sets separate valuations for specific items that commonly come with an addition or an outdoor remodel. These figures are adjusted annually using a construction cost index, according to the bulletin, so they move independently of the main occupancy table above.
| Item | Valuation |
|---|---|
| Patio cover or balcony | $45 / sq ft |
| Carport | $26 / sq ft |
| Retaining wall (concrete or masonry) | $55 / sq ft |
| Swimming pool (vinyl-lined) | $104 / sq ft of surface area |
| Re-roofing, asphalt low-slope | $494 / square (100 sq ft) |
| Unfinished basement (R-3) | $31.50 / sq ft |
- These miscellaneous figures stand on their own — they aren’t added to the R-3 per-square-foot rate for the same square footage, since they cover items the main occupancy table doesn’t price.
- A detached, private garage uses the “Utility, miscellaneous” rate from the main table rather than the R-3 residential rate, even on a lot with a single-family home.
- If an item you’re pricing isn’t listed in either table, the bulletin directs plan check staff to make a case-by-case determination rather than leaving the valuation blank.
When there’s no new floor area
Not every remodel adds square footage. Converting a window into a slider, closing up an old exterior opening, or adding an interior partition wall changes the structure without adding floor area, so Information Bulletin 101 values these alterations on a separate, smaller schedule.
| Alteration | Valuation |
|---|---|
| Interior partition wall | $151 / linear ft |
| New window or sliding glass door | $46 / sq ft of opening |
| Closing an exterior wall opening | $45 / sq ft of opening |
For a project that changes a space’s use without adding floor area — enclosing an open porch, for instance — the bulletin’s instruction is to value the work as the difference between the existing use’s per-square-foot rate and the new use’s rate, rather than charging the full new-use rate on space that already existed.
What fees actually use this number
Valuation isn’t just a line on a form. Two specific state fees are calculated directly as a rate against it, according to the city’s separate fee bulletin for construction permits: a State Seismic Fee of $0.13 per $1,000 of valuation on one- and two-family homes, and a State Building Standards Fee of $4 per $100,000 of valuation, with a $1 minimum. A full breakdown of San Diego’s building permit fee schedule covers how these sit alongside the plan-check and inspection charges that aren’t tied to valuation the same way.
Because these two fees scale with valuation, a higher construction-type rate or a larger addition does raise them — just by cents to a few dollars per thousand, not dollar-for-dollar with your contract price. Don’t confuse a change in valuation with a proportional change in your total project cost; the two numbers answer different questions. For a sense of what remodeling and additions actually tend to cost in the local market, see our breakdown of home addition costs in San Diego.
Information Bulletin 101’s main per-square-foot table is sourced from industry construction-cost data dated August 2023, according to the bulletin itself. That means in a period of fast-moving material and labor costs, the published valuation rate can run behind what a project actually costs to build in the current market — it’s an administrative figure, not a budgeting tool.
Partial and phased permits
Larger projects sometimes pull permits in phases rather than all at once, and Information Bulletin 101 sets specific percentages of total project valuation for each phase:
- Foundation only: 10% of total project valuation.
- Structural frame only: 50% of total project valuation.
- Build-out with no tenant improvements: 20% of total project valuation.
- Shell-only buildings: valued at 80% of the total project valuation.
These percentages exist so the city can collect fees proportional to the phase being permitted, rather than charging full-project fees on a foundation-only submittal. If you’re planning a phased addition or new construction project, ask your designer which phase percentages apply before you budget your permit timeline.
Frequently asked questions
Is my permit “valuation” the same as what I’m paying my contractor?
No. The valuation is a figure the city calculates from a published per-square-foot schedule (Information Bulletin 101), based on your project’s occupancy group, construction type, and square footage. It is not based on your signed contract or your contractor’s invoice, and the two numbers are often different.
What occupancy group does my single-family remodel or addition fall under?
Most single-family remodels and additions in San Diego are classified as Group R-3, residential one- and two-family. Multi-family buildings use Group R-2, and detached garages are valued separately under the city’s “Utility, miscellaneous” classification.
Which construction type applies to a typical San Diego home?
Most single-family homes and additions in the county are standard wood-frame construction, which the schedule lists as Type V-B or Type V-A. Your plan set determines the exact type — never assume it from a photo or a general description of the home.
Does a garage conversion get valued as living space or as a garage?
A standalone garage is valued at the “Utility, miscellaneous” rate. If you’re converting a garage to living space, Information Bulletin 101 directs applicants to value the change as the difference between the existing use’s rate and the new use’s rate, not the full R-3 rate applied on top of the existing valuation.
Are these valuation rates adjusted over time?
Yes, on two different schedules. The main per-square-foot table is sourced from industry Building Valuation Data, with the version cited in the current bulletin dated August 2023. The separate miscellaneous-items table is adjusted annually using a construction cost index, according to the bulletin.
Does a higher valuation mean I owe more in permit fees overall?
It raises two specific state fees that are calculated as a rate against valuation: a $0.13-per-$1,000 State Seismic Fee on one- and two-family homes, and a $4-per-$100,000 State Building Standards Fee (with a $1 minimum). Most other plan-check, inspection, and issuance fees are set separately and aren’t a straight percentage of valuation.
What if my project doesn’t add any new floor area?
Work like closing an exterior wall opening, adding a window, or building an interior partition uses a separate, smaller valuation table rather than the main per-square-foot schedule, since no new floor area is being created.
