APPLY FOR PERMITS ONLINE!

As of January 1, 2025, the 2025 California Building Codes and 2025 California Fire Code have been effective in the City of Lompoc, along with previously adopted amendments to those codes. Chapter 3 addresses the subject of when building permits are or are not required.

So, You Want to Build Something? A Guide to Building Permits in Lompoc

The General Rule
If you (or your agent) intend to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building—or if you're messing with electrical, gas, mechanical, or plumbing systems—you must apply for and obtain a permit first. Yes, that includes replacing systems, not just new ones.

When You Can Skip the Permit (The Exemptions)
We aren't total sticklers. There are a few things you can do without our blessing, provided they don't violate other laws or zoning rules:

• Small Structures: One-story detached accessory structures (like sheds or playhouses) under 120 square feet. Just keep in mind that if you’re in a Wildland-Urban Interface area, we might still have a few words to say about materials.
• Wood Fences: As long as they aren't over 7 feet high (and aren't acting as a swimming pool barrier).
• Retaining Walls: If they are 4 feet or less from the bottom of the footing to the top of the wall, and aren't supporting a surcharge (extra weight from above).
• Water Tanks: Up to 5,000 gallons, provided the height-to-width ratio is no more than 2:1 and they sit directly on the ground.
• The Aesthetics: Painting, papering, tiling, carpeting, cabinets, and countertops. Basically, the "fun stuff" is usually exempt.
• Decks: If they are 200 square feet or less, no more than 30 inches above grade, and aren't attached to the house or serving a required exit door.

Service System "Light" Work
You don't need a permit for minor repairs and maintenance, such as:

• Electrical: Replacing lamps or connecting portable equipment to existing receptacles.
• Plumbing: Clearing stoppages or fixing leaks in pipes and valves—as long as you aren't rearranging the whole setup.
• Mechanical/Gas: Portable heating, ventilation, or cooling units.

The "No-Go" Zone (Always Requires a Permit)
Don't even think about doing these without a permit, even if you consider it a "repair":

1. Cutting away any wall or partition.
2. Removing or cutting any structural beam or load-bearing support.
3. Changing any part of a required exit (means of egress).
4. Any addition or relocation of water, sewer, gas, or electrical lines.

A Note on Lompoc Zoning
In our lovely City of Lompoc, your accessory structures must still respect property lines. Detached accessory structures generally need to be in the rear half of the lot with a minimum of 5 feet between buildings. If you're in a residential zone, height limits apply near property lines, so check Figure 17.304.020.2 before you go vertical.

Remember: Even if a permit isn't required, you must still follow the building codes. Safety isn't optional!
