Managing multi-unit properties in San Diego comes with a long to-do list—and renovations are often one of the biggest, most complex tasks on it. Whether you’re upgrading a single unit between tenants or planning a full property overhaul, apartment renovations require thoughtful coordination, budgeting, communication, and the right contractor to bring it all together.

At McMillin Contracting Services, we’ve worked alongside property managers for over 25 years to simplify the renovation process. We understand your priorities—minimizing downtime, maximizing property value, and staying on schedule and budget. This guide breaks down the process to help you manage apartment renovations smoothly and efficiently from start to finish.

Step 1: Define the Scope of Work

Before you make any calls or pull permits, get clear on what you want to renovate and why. Are you:

1. Updating outdated units to attract better tenants?

2. Addressing structural or code-compliance issues like balconies or staircases?

3. Improving curb appeal with exterior upgrades?

4. Reconfiguring layouts to maximize square footage?

Create a list of priorities, noting whether each item is a must-have or nice-to-have. This helps you stay focused, communicate clearly with contractors, and make smart decisions when budget or time constraints arise.

Step 2: Set a Realistic Budget

Once the scope is outlined, estimate a realistic budget—and include a cushion (usually 10–15%) for unexpected issues. Things like outdated wiring, water damage, or permit delays can impact costs.

If you’re unsure where to start, McMillin offers correct estimates to help you get a sense of the investment required. Whether you’re budgeting for a quick kitchen remodel or a full exterior refresh, we’ll work with you to find solutions that meet your goals without breaking the bank.

Step 3: Choose the Right Contractor

The contractor you choose can make or break your renovation experience. You need someone who is:

✔ Experienced in multi-unit projects
✔ Familiar with local permitting and code compliance
✔ Responsive and communicative
✔ Capable of working around occupied units

At McMillin Contracting Services, we specialize in apartment and condo renovations throughout San Diego. We’re known for our clear timelines, consistent communication, and the ability to deliver results—without disrupting your tenants or dragging out the project.

Step 4: Plan Around Occupancy

Occupied renovations require extra care and planning. If you’re upgrading common areas, balconies, or exteriors, you’ll need to notify tenants in advance, set clear expectations, and minimize noise or accessibility issues.

When it comes to unit turns, McMillin’s team can step in quickly between tenants to handle painting, flooring, cabinets, bathrooms, and more—so you can list the unit fast and keep vacancy rates low.

Step 5: Don’t Skip Permits or Compliance

A huge pain point for many property managers is dealing with permits and code compliance. Especially for balcony work under California’s SB721 and SB326, you need to be working with licensed professionals who understand the process—and can help you avoid penalties or delays.

Unfortunately, many property owners hire the wrong inspectors, get unclear reports, or face slow permitting timelines. At McMillin, we handle the compliance headache for you. We’ll guide you through inspections, engineer plans if needed, obtain proper permits, and complete the work in full compliance with local regulations.

Step 6: Insurance Work? We’ve Got That Too

Was your renovation prompted by damage? Whether it’s water intrusion, fire, or balcony deterioration, dealing with insurance can be a battle. If your insurance company is giving you trouble, let us help. McMillin has experience with insurance work.  

Step 7: Communicate Often

During any renovation, clear and regular communication is key—especially in multi-unit properties. Keep your tenants in the loop with notices about work timelines, safety precautions, and temporary disruptions. And work with a contractor who communicates with you just as frequently.

At McMillin, we provide real-time updates, quick responses, and transparency at every stage—so you’re never left wondering what’s next.

Step 8: Final Walkthrough & Quality Check

Once renovations are complete, do a final walkthrough with your contractor to ensure everything meets expectations. Make note of any final touch-ups or concerns and get confirmation that all work was done to code.

Our team at McMillin prides itself on doing the job right the first time—but we’re always happy to go the extra mile if something needs attention before project closeout.
