How Santee building permits are filed

Santee’s Planning & Building Department is at 10601 Magnolia Ave., Building 4. The main line is 619-258-4100 ext. 167, and counter hours are Monday through Thursday 8 a.m. to 5 p.m. and Friday 8 a.m. to 1 p.m. The city takes permit submittals through its online portal only. It does not accept paper plans, and it does not offer expedited review.

Permit types the city lists

• ADU
• Residential alteration
• Residential new construction
• Electrical
• Mechanical
• Plumbing
• Solar and SolarAPP

The city also publishes a list of work that does not need a permit, so check it before you assume a small job is exempt. For the exact fee on a project, use the city’s fee schedule or ask the counter.

Steps for a typical Santee permit

1. Confirm the job needs a permit. Compare the work against the city’s no-permit list.
2. Prepare plans and forms. Planning forms and checklists are posted on the city’s documents page.
3. Submit through the portal. Upload the plans and documents online.
4. Respond to plan check comments. Corrections go back through the same portal.
5. Pay, build and inspect. Keep every inspection sign-off, because a buyer will ask for the final.

Santee ADU permits and what changed

Santee runs ADU permits through the same portal. The city’s ADU fee waiver ended on September 27, 2024, so fees now apply. New ADUs must meet 2022 CALGreen Tier II and the standards in Santee Municipal Code section 13.10.040 (J and K). Under AB 1332 the city accepts preapproved ADU plans from San Diego County, Chula Vista and Encinitas, which can shorten the design stage.

For an ADU built before January 1, 2020 without a permit, state law (AB 2533) lets an owner apply to legalize it, and the city uses a Substandard Structure Checklist as part of that review. Ask the counter at ext. 167 how it applies to your address.

Other Santee programs that can affect a project

• SB 9: the city has an SB 9 guide for two-unit projects and urban lot splits.
• SB 330: a preliminary application can lock in the rules that apply to a housing project.
• Essential Housing: a city ordinance (Ordinance 592, adopted 2021) for certain housing projects.
• Density bonus and by-right zoning: the city’s code includes density bonus rules and a by-right chapter, SMC 13.11.
• CEQA exemptions: the city lists several, including Guidelines sections 15183 and Class 32.

These mostly matter to owners with larger lots, but a buyer who plans to add units will ask what the lot already allows.

Permit gaps that surface when you sell

Open permits, expired permits and finished work with no permit at all are the three problems buyers and their lenders find most often. A converted garage, a patio cover turned into a room, a panel upgrade or a second kitchen are common examples. Ask the city counter whether the address shows open permits before you list, and gather final inspection records for any work you did.

Selling a Santee home that has unpermitted work

You have four realistic routes: finish and close the permit, pull a new permit and legalize the work, remove the work, or sell the home as-is and disclose it.

California sellers must disclose known unpermitted work on the transfer disclosure statement, which is covered in our as-is and unpermitted work guide. A cash buyer can purchase with the permit gap in place, and you can compare net proceeds with the seller closing costs guide.

Checklist before you list a Santee home

• Pull the permit history for the address.
• Locate final inspection records for additions, roofs, water heaters, HVAC and solar.
• List any work done without a permit and decide whether to fix, legalize or disclose it.
• Confirm the square footage you plan to advertise matches permitted space.
• Review the natural hazard disclosure guide so the paperwork is ready.

Questions to ask the Santee counter

• Does this address show any open or expired permits?
• Was the garage, patio or room addition finaled?
• Would the work I did need a permit today, even if it did not when it was built?
• If I want to legalize an older unit, which documents are required?
• What would it cost and how long would it take compared with selling as-is?

Time and cost: legalize or sell as-is

Legalizing work means plans, plan check, corrections, fees, construction and inspections, all through a portal with no expedited path. For a seller who needs to close quickly, that timeline can matter more than the cost. Selling as-is trades some price for speed and certainty.

A written cash offer that accounts for the permit gap lets you weigh both honestly, and our team can walk through the numbers with you at no cost.

Work Santee says does not need a building permit

The city publishes a list of activities that do not require a building permit, with the reminder that the work must still comply with the municipal code, including zoning and building codes. Highlights from that list:

• Sheds and playhouses: one-story detached structures with a floor area of 120 square feet or less. Location and height should be verified with Planning and Padre Dam.
• Fences: not over 6 feet high, measured from the bottom of the footing.
• Retaining walls: not over 3 feet high, unless they support a surcharge. New walls may still need a grading permit, so check with Engineering before starting.
• Sidewalks and driveways: not more than 30 inches above adjacent grade, with Padre Dam approval required.
• Prefabricated pools: installed entirely above ground, less than 24 inches deep and not more than 5,000 gallons, again with Padre Dam approval.
• Finish work: painting, papering, tiling, carpeting, cabinets and countertops.
• Window awnings: supported by an exterior wall and projecting no more than 54 inches.
• Minor repairs: ordinary repairs that do not cut away walls, remove structural beams, change egress or alter piping, wiring or mechanical work. Emergency equipment replacements still require an application within two working days.

The city’s list states that an exemption does not authorize work that violates the code or other laws. If a project is borderline, call the Planning and Building Department at 619-258-4100 before you start.

Counter hours and portal

The city lists the Planning and Building line as 619-258-4100, with hours of Monday to Thursday 8:00 a.m. to 5:00 p.m. and Friday 8:00 a.m. to 1:00 p.m. Applications go through the city’s permitting and licensing portal. Confirm hours before you visit, since they change.

Common mistakes

• Trying to file paper plans when the city accepts submittals through the portal only.
• Assuming an old permit from a prior owner was finalized.
• Waiting until a buyer’s inspection to find an open permit.
• Leaving unpermitted space in the listing square footage.
