What Multifamily Property Management Costs in San Diego: A Fee-by-Fee Breakdown

Updated August 2026  ·  Scott Engle, Broker DRE #01332676, Corp DRE #02075336  ·  Realty Management Group  ·  San Diego County, CA

Two San Diego owners can hold identical six-unit buildings, collect identical rent, and pay $8,572 a year apart for property management. Neither of them knows it, because the difference never appears on a single invoice.

If you own a small apartment building, you have probably noticed the pattern without naming it. The management fee on the statement looks reasonable. Repairs come back higher than the vendor quoted. A tenant moves out and a charge appears that you do not remember agreeing to. At the end of the year the cash flow is a few thousand dollars short of what the spreadsheet said, and no single line item explains it.

That is what this page is about. Not the advertised percentage — the per-unit minimums and per-event charges underneath it that multiply by every door you own. Every figure below comes from a published San Diego fee schedule, and the arithmetic is shown so you can run it on your own building.

Every competitor figure on this page comes from that company's own published pricing page, retrieved August 2026, and is named in the methodology at the foot of the post. Where a company does not publish a fee, this page says so rather than estimating.

The Per-Unit Minimum: The Line That Decides Everything

Most multifamily fee comparisons start with the percentage. That is the wrong starting point, because published San Diego schedules apply a monthly minimum per unit, and on a multi-door building the floor usually binds before the percentage does.

One San Diego company publishes 6% of collected rent for buildings of 5–15 units, with a minimum of $170 per unit per month. Sources for every figure on this page are named in the methodology at the foot of the post. Here is what that rate actually costs at different rent levels:

This is not a criticism of that schedule. It is published clearly and it is a defensible way to price. The point is that comparing it to a competitor's 8% tells you almost nothing until you know both minimums and your own rents.

The Published Multifamily Fee Stack

Below are the fee schedules published by San Diego County companies for multi-unit residential buildings. Where a company does not publish a figure, that is stated rather than filled in.

A third San Diego company publishes 8–10% with no leasing or renewal fees, but does not publish an inspection fee or maintenance markup, so it is not included in the worked comparisons below.

Worked Example: Six Units at $3,500

A six-unit building at $3,500 per unit — $252,000 in gross annual rent. One unit turns over during the year, five renew. Assume $8,000 in total repair spend and one annual inspection cycle.

The Breakeven Rent, by Percentage

The arithmetic is simple: divide the flat fee by the percentage. Above the resulting rent, the flat fee is cheaper on base management alone, before any event fees enter the calculation.

Cost by Building Size

All figures at $3,500 per unit, calculated from the published schedules above, with one turnover per year on buildings up to six units and two on larger ones.

The four-unit row uses the 8% tier with a $210 per-unit minimum, since that schedule's 6% tier begins at five units. Change the rent, the turnover assumption, or the repair spend and these totals move — the calculation is shown above so you can run your own.

What This Does to NOI and Value

Management fees are an operating expense, so they reduce net operating income dollar for dollar. Because income property is valued off NOI, a permanent reduction in a recurring expense affects value as well as cash flow.

On the six-unit example, a $4,982 annual difference at an illustrative 5.2% cap rate corresponds to roughly $96,000 in value. Against the higher-cost schedule, an $8,572 difference corresponds to roughly $165,000.

Compliance Costs Specific to Multifamily

Every compliance obligation below repeats on every door, which is why it belongs in a cost discussion rather than a separate legal one.

Frequently Asked Questions

What does multifamily property management cost in San Diego?

Published San Diego rates for buildings of five or more units run around 6% of collected rent with a per-unit monthly minimum near $170, or 8% on smaller buildings. Additional published charges include a leasing fee of up to 25% of one month's rent per placement, renewal fees up to $195 per unit, inspection fees of $150 to $250, and maintenance coordination markups up to 10%. On a six-unit building at $3,500 per unit, those schedules produce annual totals between $12,888 and $21,460 — effective rates of 5.1% to 8.5% of gross rent.

What is a per-unit monthly minimum and why does it matter on a multifamily building?

A floor beneath the percentage, applied separately to each door. A published 6% rate with a $170 per-unit floor produces an effective 9.4% on an $1,800 unit, 7.7% on a $2,200 unit, and 6.1% on a $2,800 unit. The floor binds on any unit renting below about $2,833. It is the single most consequential line on a multifamily fee schedule and the one owners most often fail to ask about.

Is flat-fee management always cheaper for multifamily?

No. Against a 6% tier, a $179 flat fee is more expensive on base management at any rent below $2,983 — at $2,800 the tier's $170 per-unit floor applies, making the flat fee $9 per door per month higher, or $648 a year across six units. On those buildings the flat fee wins only because it carries no leasing, renewal, inspection, or markup charges. Against an 8% rate with no minimum, $179 is cheaper above $2,238 in monthly rent and more expensive below it.

How do I calculate the breakeven between a flat fee and a percentage?

Divide the flat fee by the percentage. At $179 against 8%, breakeven is $2,238 per month; against 9%, $1,989; against 10%, $1,790. Two cautions: this covers base management only, so leasing and renewal fees push the real breakeven considerably lower, and if the percentage carries a per-unit minimum, the minimum governs at lower rents rather than the percentage.

Do multifamily managers in San Diego charge leasing fees?

Some do and some do not. One published schedule charges 25% of one month's rent per placement. Two others charge none on full-service management. Realty Management Group charges none. Because it varies this much for identical work, treat a leasing fee as a negotiable line item rather than an industry standard.

Does AB 1482 apply to a duplex or fourplex in San Diego?

Almost always, if completed before January 1, 2011. Multi-unit apartment buildings do not qualify for the single-family and condo exemption, so the 8.2% rent cap for August 1, 2026 through July 31, 2027 and the just-cause requirements apply. Only the under-15-year new-construction exemption removes a building from coverage, and that threshold advances every January.

How do management fees affect multifamily property value?

Management fees are an operating expense, so a permanent reduction raises net operating income, and income property is valued off NOI. At an illustrative 5.2% cap rate, roughly $1,000 a year in permanently lower expense corresponds to about $19,000 in value, for as long as the difference holds. Cap rates vary by submarket and condition, the effect reverses if you switch back, and a one-time cost such as a single vacant month does not capitalize this way — only a recurring change does.

Does Realty Management Group manage small apartment buildings?

Yes. Realty Management Group manages 1–16 unit properties throughout San Diego County, including El Cajon, La Mesa, Chula Vista, Mission Valley, Santee, and San Marcos. Flat fee: $199 per month for 1–3 units, $179 per unit per month for 4–16 units, 6% above $5,000 in monthly rent per unit.
