San Diego ADU permit and inspection prep guide for fewer delays

Imagine walking through the finished space and everything feels intentional: proportions, lighting, storage, and the small details that make the room feel easy.

This San Diego guide is written from a designer perspective. The goal is to help you make confident decisions before construction starts, so your remodel feels calm, functional, and built to last. Cali Dream Construction is a design build general contractor serving San Diego County with a focus on kitchens, bathrooms, ADUs, and whole home remodeling.

Designer lens

One lens that keeps decisions consistent is a timeless base with one confident accent. When a remodel feels cohesive, it is usually because one guiding idea was used for layout, materials, and details.

What this guide covers

How permitting and inspections affect planning
How to move from ideas to a buildable scope
How to compare bids fairly
What good project communication looks like

The ADU design decision that usually matters most

ADUs feel high quality when entry, storage, light, and privacy are designed intentionally. A simple palette and efficient plan often outperform complicated ideas.

Design first decisions

Confirm what is included and excluded before signing
Define scope in writing, not just in conversation
Set allowances that match your taste level
Plan a decision schedule so choices are made early
Choose a communication cadence that keeps things calm

Common mistakes and how to avoid them

Starting without a clear plan for inspections and access
Ignoring site protection and daily cleanup expectations
Signing without understanding allowances and change order rules
Not confirming who is ordering materials and when
Comparing bids with different scopes and assumptions

Worksheet you can copy into your notes

This worksheet is simple on purpose. Fill it in before you request bids so you can compare proposals on the same scope.

San Diego specific planning note

San Diego homes can range from coastal humidity to warmer inland days. That range affects material choices, ventilation planning, and how we think about comfort.

Budget and timeline note

Process is what protects both budget and schedule. A clear scope, a clear communication cadence, and early selections reduce the most common causes of delays.

If you want numbers for your specific home, the best next step is a walkthrough so we can measure, discuss scope, and identify constraints.

Permits and inspections in San Diego

Permitting depends on scope and on the authority having jurisdiction. In San Diego County, many projects are reviewed by the City of San Diego Development Services or by County of San Diego Planning and Development Services, but some cities have their own building departments.

Common triggers include changes to plumbing, electrical, structure, openings, or creating new dwelling space. We discuss permit needs early so inspections do not surprise the schedule.

Frequently asked questions

Do I need permits for this type of work?

If the work changes plumbing, electrical, structure, or creates new dwelling space, permits are commonly required. The exact requirement depends on scope and jurisdiction, so we verify early.

How do I start planning without getting overwhelmed?

Start with the problem you are trying to solve, then choose one guiding design direction. A walkthrough and a measurement based plan turn inspiration into a buildable scope.

How do I keep the design from feeling dated?

Use timeless fundamentals: good proportions, a calm base palette, and strong lighting. Add personality through elements that can be updated later.

What makes an ADU feel like a real home?

A clear entry moment, smart storage, good light, and a cohesive material palette repeated across the unit.

What design choice helps an ADU rent well?

Durable finishes, privacy, and a complete kitchen and bathroom. Good lighting and storage also matter more than most people expect.
