San Juan full kitchen remodel permits — the key details

San Juan requires a permit for any full kitchen remodel in which one or more of the following occurs: a wall is moved or removed (especially load-bearing walls under IRC R602, which require engineering and inspection); any plumbing fixture (sink, dishwasher, refrigerator water line) is relocated to a new location (per IRC P2722 for drainage and trap-arm sizing); a new electrical circuit is added (per IRC E3702 for small-appliance branch circuits, which now require two independent circuits serving counter outlets); a gas line is modified or extended to a new appliance location (per IRC G2406); a range hood is vented to the exterior through a newly cut wall opening; or window or door openings in the kitchen are changed (structural opening modification). The threshold is deliberately low: even if you're only moving a sink 3 feet and keeping the cabinet footprint the same, you need a plumbing permit because the drain and supply lines are being re-routed. The City of San Juan Building Department will require separate applications for building, plumbing, and electrical, each with its own fee and inspection sequence.

Cosmetic-only work is exempt from permitting and includes cabinet replacement in the same location without structural support changes, countertop removal and replacement (laminate to quartz, for example, in the same footprint), vinyl plank or ceramic tile flooring, paint, hardware swaps, and appliance replacement with the same electrical and gas connections as the old unit. If you are replacing a gas range with an electric range or vice versa, that IS a gas-line modification and requires a permit. If you are replacing a range hood with one of identical ducting location and capacity, that is exempt; if you are adding exterior venting where there was none, or moving the duct exit, that requires a permit. The distinction hinges on whether new trades, new structural work, or new exterior penetrations are involved.

San Juan's position in the Rio Grande Valley means kitchen remodels often touch on flood-zone compliance and clay-soil settlement. If your property is in a FEMA flood zone, the building permit will include elevation verification, and plumbing work must be reviewed against flood-plain standards (typically requiring water heaters and electrical panels above base flood elevation). The expansive Houston Black clay common in the area can shift under footings, and while kitchen work usually does not involve new foundation loads, the city inspector may flag any wall removal that affects vertical load paths to the slab. Concrete flatwork around the exterior range-hood vent location may also be scrutinized if it is within 5 feet of the foundation. Plan-review time in San Juan is typically 2–4 weeks because all three sub-permits (building, plumbing, electrical) must clear before you receive the final green light. Do not assume you can pull the building permit first and submit the plumbing later; the city will require all three applications and plans before plan review begins.

The permit application package must include a site plan showing the kitchen layout (floor plan with dimensions, existing and proposed appliance locations, window and door locations), electrical plan showing the two small-appliance branch circuits (IRC E3702) with GFCI protection on all counter receptacles (IRC E3801; receptacles must be spaced no more than 48 inches apart along the counter), plumbing plan with drain and vent routing (especially the kitchen sink drain trap-arm slope and any dishwasher drain connection per IRC P2722), gas plan if applicable, and range-hood duct termination detail showing exterior wall cap and clearances. If a wall is being removed, a letter from a licensed engineer or an affidavit of design from a licensed architect stamped and dated is required to confirm the wall is non-load-bearing or to detail the beam or support that replaces it. All plans must be drawn to scale (typically 1/4 inch = 1 foot for floor plans) and signed by the applicant or contractor. San Juan Building Department accepts plans via in-person submission at City Hall; verify whether electronic submission is available by contacting the department directly.

Inspections are staggered and cannot be skipped: rough plumbing (before drywall, to verify drain and vent routing and trap dimensions), rough electrical (before drywall, to verify circuit routing and outlet box placement), framing (if walls are moved), drywall, and final (with all fixtures and appliances installed and operational). Each trade must schedule its own inspection, typically with 24 hours' notice to the city. The final inspection includes verification that GFCI outlets are functioning, range hood is ducted and capped at the exterior, gas connections are pressure-tested (if applicable), and plumbing fixtures drain freely. San Juan's inspector may also verify that any countertop openings for cooktops, sinks, and appliances are properly sealed at the underside to prevent water intrusion into the cabinetry. Expect the entire permit-to-final-sign-off process to take 6–10 weeks if there are no rejections or rework requests. If you are the owner-builder and the property is your primary residence, you may be able to pull the permits yourself, but you will still be responsible for scheduling inspections and ensuring work meets code.

Three San Juan kitchen remodel (full) scenarios

Small-appliance branch circuits and GFCI protection in San Juan kitchens

IRC E3702 and E3801 are the two most commonly missed code sections in San Juan kitchen permits. IRC E3702 requires that all counter receptacles in a kitchen be served by a minimum of two independent, separate 20-amp small-appliance branch circuits; no other outlets (lighting, garbage disposal, dishwasher) may be connected to these circuits. Many older homes have a single 15-amp general circuit serving the entire counter, and when homeowners or contractors fail to add a second dedicated circuit, the plan-review stage catches it and the application is rejected. San Juan's building department will not approve a permit for a full kitchen remodel without evidence of two small-appliance circuits on the electrical plan. Each circuit must originate from a separate breaker in the main panel and must be clearly labeled on the plan. Additionally, IRC E3801 mandates that all receptacles serving kitchen countertop surfaces within 6 feet of a sink be GFCI-protected; receptacles within 6 feet horizontally or 2 feet vertically of the sink edge must have either GFCI outlets or be protected by a GFCI breaker. Counter receptacles must be spaced no more than 48 inches apart (measured along the countertop edge), so a 10-foot counter will need a minimum of 3 outlets, all GFCI-protected. If you are using a single GFCI breaker to protect multiple outlets on one circuit, the electrical plan must clearly show the GFCI source and all protected outlet locations.

San Juan's electrical inspector will test GFCI function at the final inspection using a test button and a GFCI test plug; if the outlet does not trip within 25 milliseconds, the inspection will fail. This is not a cosmetic issue—GFCI protection is a life-safety requirement that prevents electrocution from water contact. If your contractor submits a plan showing a single 15-amp circuit and only one outlet on the counter, the plan will be rejected, and you'll have to resubmit and restart the 2–4 week review clock. To avoid this, verify with your electrician upfront that two independent 20-amp circuits are shown on the plan and that all counter receptacles are GFCI-protected and spaced correctly. This is one of the few code sections that San Juan inspectors enforce consistently and without exception, so do not try to work around it.

In newer homes or homes with recent electrical updates, the panels may already have capacity for two new circuits. In older homes, especially those from the 1960s or 1970s, the main panel may be full (e.g., a 100-amp service with 24 breaker slots all in use). If your panel is full and you need two new circuits, you have two options: upgrade the main service from 100 amps to 150 or 200 amps (cost: $2,000–$5,000 and a separate permit), or use tandem/twin breakers if the panel permits and if space is available. The electrical contractor will determine feasibility during the permitting phase; if a service upgrade is needed, this will extend the timeline by 1–2 weeks and increase the total permit cost.

Plumbing drain and vent routing in San Juan's clay-soil environment

San Juan sits on expansive Houston Black clay, which is prone to shrinkage and settling, especially in areas with poor drainage or high water tables. This affects kitchen plumbing permits because the city inspector will verify that any relocated plumbing lines maintain proper slope and do not create low spots where water can pool in the vent lines. IRC P2722 requires that kitchen sink drains be trapped (a U-bend that holds water to prevent sewer gases from entering the home) and that the trap-arm (the horizontal section between the trap and the main vent stack) slope at a minimum of 1/8 inch per foot and a maximum of 1/2 inch per foot; if the slope is too steep, the water moves too fast and leaves solids behind; if it is too shallow, water pools and blocks drainage. If you are relocating a sink even 3 feet away from its current location, the plumber must re-run the drain line and ensure the slope is correct. The inspector will check this during the rough-plumbing inspection by looking at the dry line (before it is connected and before final countertop installation) and measuring the slope with a level.

Vent-stack sizing is also critical. When a sink is added or relocated, the plumber must verify that the existing vent stack has capacity for the new load; if the stack is undersized or if the new sink is on a branch vent with low slope, the stack must be upgraded. The vent termination (the roof penetration or wall opening) must be at least 10 feet from any window, door, or exhaust intake, and at least 6 inches above the roofline (per IRC P3103). In San Juan's humid climate, the inspector will also check that the vent termination has a cap to prevent rainwater from entering the drain system; a missing or improperly installed vent cap is a common reason for rough-plumbing inspection failures and must be corrected before drywall is closed.

If your kitchen sink is being relocated to a different part of the home (e.g., from the south wall to the north wall, 15 feet away), and the existing vent stack is not positioned to serve the new location without an excessively long branch run, you may need to tie into an alternate vent or install a new vent line to the roof. This significantly increases the complexity and cost of the plumbing work and must be shown on the plumbing plan submitted with the permit. San Juan's building department will reject a plumbing plan that does not clearly show vent routing and sizing, so work with your plumber to ensure the plan is complete and accurate before submission. The rough-plumbing inspection is the last chance to correct vent or drain slope issues before the lines are buried in the wall or under the floor.
