How Much Do Electrical, Plumbing & HVAC Permits Cost for a Remodel in San Diego?
A kitchen or bathroom remodel in San Diego almost always triggers three separate permit fees on top of your building permit: one for electrical, one for plumbing, and one for mechanical work. Here is the city’s current fee schedule, line by line, and what it typically adds up to.
Key takeaways
- MEP permits are billed separately from your building permit. Electrical, plumbing, and mechanical work each carry their own fee line under the city’s Information Bulletin 103.
- A typical bathroom remodel’s MEP fees run about $723.37 when it includes new plumbing fixtures, a vent fan, and up to five new circuits — before any building permit or plan check fee is added.
- Kitchen remodels usually add more circuits. The first five new circuits cost $176.57 combined; the sixth through tenth add $52.39 each.
- Only a properly licensed contractor can pull certain MEP permits. California requires a C-10 license for electrical work, a C-36 for plumbing, and a C-20 for HVAC and mechanical work.
- These are government fees, not an Eco Home Builders price. They are a small line item next to your total project cost, and they are separate from labor, materials, and design.

What Is an MEP Permit, and Why Is It Separate?
“MEP” stands for mechanical, electrical, and plumbing — the three trades that keep a remodeled kitchen or bathroom running water, power, and air. The City of San Diego’s Development Services Department bills each of these trades on its own fee schedule, published as Information Bulletin 103, separate from the building permit fee that covers framing, drywall, and structural work under Information Bulletin 501.
In practice, that means a single remodel can generate up to four permit fee lines: one building permit fee based on the project’s construction valuation, plus a plumbing fee, an electrical fee, and a mechanical fee, each priced by the specific item of work rather than by the project’s overall cost. Knowing this ahead of time keeps the number on your city receipt from looking like a mystery — or, worse, like the price of your remodel itself.
When Does a Kitchen or Bathroom Remodel Trigger MEP Fees?
Almost any kitchen remodel or bathroom remodel that moves or adds a fixture, outlet, or vent will cross into MEP fee territory. A new dishwasher circuit, a relocated sink, a range hood vent, or a bathroom exhaust fan are each billed as their own line item under Information Bulletin 103 — regardless of whether the rest of the project needs a building permit at all.
These fees sit alongside the general question of whether your project needs a permit in the first place, which we cover separately for a kitchen remodel permit and a bathroom remodel permit. This guide picks up after that question is answered “yes” and walks through what the city actually charges for the electrical, plumbing, and mechanical trades once permits are required.
San Diego’s MEP Permit Fee Schedule at a Glance
The table below pulls the fee lines a residential kitchen or bathroom remodel is most likely to hit, straight from Information Bulletin 103. Every figure is a permit fee charged by Development Services — not a materials cost, not a contractor’s price, and not part of the fixture itself.
| Permit type | Common remodel item | Permit fee |
|---|---|---|
| Plumbing | Kitchen or bathroom remodel, existing home (per dwelling unit) | $440.82 |
| Plumbing | Water heater replacement | $122.97 |
| Plumbing | Backflow preventer, first unit | $87.68 |
| Mechanical | Exhaust fan (range hood or bathroom vent) | $105.98 |
| Mechanical | Furnace, air handler, or mini-split, first unit | $176.57 |
| Electrical | New circuits, first five combined | $176.57 |
| Electrical | Each additional circuit, sixth through tenth | $52.39 |
| Electrical | Panel replacement or upgrade, up to 200 amps | $176.57 |
Example: Stacking the Fees for a Real Remodel
Permit fees for a remodel rarely come from a single table row — a bathroom remodel typically pulls one fee from each trade, and a kitchen remodel with more circuits pulls a bigger electrical line. The table below shows how the line items in Table 1 combine into a total, using scopes that are common for each room.
| Remodel scope | Fee items combined | Estimated MEP total |
|---|---|---|
| Bathroom remodel: fixtures, vent fan, up to 5 new circuits | $440.82 + $105.98 + $176.57 | $723.37 |
| Kitchen remodel: fixtures, vent fan, 6–10 new circuits | $440.82 + $105.98 + $176.57 + (1–5 × $52.39) | $723.37–$985.32 |
| Kitchen remodel above, plus a panel upgrade | Row 2 total + $176.57 | $899.94–$1,161.89 |
Who Is Allowed to Pull an MEP Permit?
California ties each MEP permit to a specific contractor license classification. A general building contractor’s license does not automatically cover specialty electrical, plumbing, or HVAC work on its own — the Contractors State License Board requires the matching classification below.
| Trade | CSLB classification | Covers |
|---|---|---|
| Electrical | C-10 | Electrical Contractor |
| Plumbing | C-36 | Plumbing Contractor |
| HVAC / mechanical | C-20 | Warm-Air Heating, Ventilating and Air-Conditioning Contractor |
Before signing a permit application, ask to see the license number of whoever is pulling each MEP permit and confirm it against the classification above on the CSLB’s public license lookup.
How MEP Fees Relate to Your Building Permit
MEP fees are not a substitute for your building permit fee, and they are not calculated the same way. Your building permit fee is based on the construction valuation of the project — the city’s Building Valuation Schedule prices residential remodel work by the square foot, then applies plan check, issuance, and inspection charges from Information Bulletin 501 on top of that valuation. MEP fees, by contrast, are flat or tiered charges tied to the specific item of work, unrelated to your project’s dollar value.
That means a small remodel with a lot of new circuits and fixtures can generate MEP fees that are a meaningful share of its total permit cost, even though its building-permit valuation is modest.
The figures above are Development Services Department fees only, current as of Information Bulletin 103’s May 2026 effective date. They do not include your contractor’s cost to prepare and submit the permit, any separate plan check fee if your project needs one, or charges from other agencies such as the utility. Fee schedules are revised periodically — confirm your exact total at submittal.
How to Avoid Surprise MEP Fees at Plan Check
A few habits keep this line item predictable instead of a surprise on your permit receipt.
- Ask your contractor for a written list of every planned circuit, fixture, and vent fan before permits are submitted, so the MEP fee estimate reflects the real scope.
- Confirm early whether a panel upgrade is needed — it is a separate $176.57 electrical fee that is easy to miss if it gets added mid-project.
- Verify your contractor (or their subcontractor) holds the correct CSLB classification for each trade before signing the permit application.
- Keep the plumbing, electrical, and mechanical fee lines separate on your budget so a change in one trade’s scope doesn’t get mistaken for a change in the whole project’s price.
Do I need a separate permit for electrical, plumbing, and mechanical work on a remodel?
Yes, in the sense that each trade is billed on its own fee line under Information Bulletin 103, separate from the building permit fee in Information Bulletin 501. The bulletin explicitly requires standalone MEP permits for non-residential and multi-dwelling construction; for a single-family remodel, MEP scope is typically reviewed alongside the building permit application, but the fees themselves are still itemized separately. Confirm the exact permit structure for your project with Development Services at submittal.
How much is the plumbing permit fee for a kitchen or bathroom remodel?
The flat plumbing permit fee for a residential kitchen or bathroom remodel in an existing home is $440.82 per dwelling unit, per Information Bulletin 103. That figure is the city’s permit fee — it does not include the fixtures themselves or your contractor’s labor and materials.
How much does a permit cost to replace a water heater in San Diego?
$122.97, according to the plumbing fee table in Information Bulletin 103. It is a flat permit fee regardless of the water heater’s size or fuel type.
How much does it cost to add new electrical circuits during a remodel?
The first five new 15–45 amp circuits cost $176.57 combined. Each additional circuit from the sixth through the tenth adds $52.39. A kitchen remodel that adds dedicated circuits for a dishwasher, disposal, microwave, and small-appliance outlets can easily reach six or more circuits, while a bathroom remodel with a vent fan and a GFCI circuit usually stays under five.
Does a kitchen or bathroom exhaust fan need its own permit?
Yes. A new or replaced exhaust fan is billed as a mechanical permit item at $105.98, separate from the plumbing and electrical fees on the same project.
Who is allowed to pull an MEP permit in San Diego?
California requires the contractor to hold the matching specialty license: C-10 for electrical, C-36 for plumbing, and C-20 for HVAC and mechanical work, per the Contractors State License Board’s classification system. Ask to see the license number before signing a permit application.
Are MEP fees included in the building permit fees I’ve seen quoted elsewhere?
No. General building permit fees, covered in our guide to San Diego building permit fees, are calculated from project valuation under Information Bulletin 501. MEP fees are flat or tiered charges from Information Bulletin 103, billed as separate line items on top of that base fee.
