ITEM 1. BUSINESS

The partnership is a publicly-held limited partnership organized under the
California Uniform Limited Partnership Act. The partnership's General Partner is
Del Taco, Inc., a California corporation ("General Partner"). The partnership
sold 8,751 units totaling $4.375 million through an offering of limited
partnership units from March 1983 through March 1984. The term of the
partnership agreement is until April 30, 2022 unless terminated earlier by means
provided in the partnership agreement.

The business of the partnership is ownership and leasing of restaurants in
California to Del Taco, Inc. The partnership acquired land and constructed six
Mexican-American restaurants for long-term lease to Del Taco, Inc. Each property
is leased for 35 years on a triple net basis. Rent is equal to twelve percent of
gross sales of the restaurants. As of December 31, 1998, the partnership had a
total of six properties leased to Del Taco (Del Taco, in turn, has subleased two
of the restaurants).

The partnership has no full time employees. The partnership agreement assigns
full authority for general management and supervision of the business affairs of
the partnership to the General Partner. The General Partner has a one percent
interest in the profits or losses and distributions of the partnership. Limited
partners have no right to participate in the management or conduct of the
partnership's business affairs.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

Liquidity and Capital Resources

The partnership offered limited partnership units for sale between March 1983
and March 1984. 15% of the $4.375 million raised through sale of limited
partnership units was used to pay commissions to brokers and to reimburse the
General Partner for offering costs incurred. Approximately $4 million of the
remaining funds were used to acquire sites and build six restaurants.

The six restaurants leased to Del Taco make up almost all of the income
producing assets of the partnership. Therefore, the business of the partnership
is almost entirely dependent on the success of the Del Taco trade name
restaurants that lease the properties. The success of the restaurants is
dependent on a large variety of factors, including, but not limited to, consumer
demand and preference for fast food, in general, and for Mexican-American food
in particular.

The partnership receives rental revenues equal to 12 percent of gross sales from
the restaurants. The partnership earned rental revenue of $531,608 during the
year ended December 31, 1998, which represents an increase of $44,328 from 1997.
The increase in rental revenue was caused by an increase in sales at the
restaurants under lease.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS - CONTINUED

General and administrative costs increased from 1997 to 1998 due to increased
costs for printing and distribution of documents. Depreciation expense was the
same in both 1997 and 1998.

Net income increased by $42,504 from 1997 to 1998 due to the increase in
revenues of $44,143 offset by the $1,639 increase in general and administrative
expenses.

The General Partner does not believe the operations of the partnership will be
significantly impacted by the year 2000 software issue and does not believe the
year 2000 software issue will materially effect the partnerships operations,
financial position or cash flows.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards required that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
from material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. An 
audit also includes assessing the accounting principles used and significant 
estimates made by management, as well as evaluating the overall financial 
statement presentation. We believe that our audits provide a reasonable basis 
for our opinion.

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of Del Taco Restaurant Properties 
I as of December 31, 1998 and 1997, and the results of its operations and its 
cash flows for each of the three years in the period ended December 31, 1998, 
in conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic 
financial statements taken as a whole. The schedule in the index of the 
financial statements is presented for purposes of complying with the Securities 
and Exchange Commission's rules and is not part of the basic financial 
statements. This schedule has been subjected to the auditing procedures applied 
in our audits of the basic financial statements and, in our opinion, fairly 
states in all material respects, the financial data required to be set forth 
therein in relation to the basic financial statements taken as a whole.

                                DECEMBER 31, 1998


NOTE 1 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE PARTNERSHIP: Del Taco Restaurant Properties I (a California limited
partnership) was formed on November 30, 1982, for the purpose of acquiring real
property in California for construction of six Mexican-American restaurants to
be leased under long-term agreements to Del Taco, Inc. (General Partner for
operation under the Del Taco trade name).

BASIS OF ACCOUNTING: The partnership utilizes the accrual method of accounting
for transactions relating to the business of the partnership. Distributions are
made to the general and limited partners in accordance with the provisions of
the partnership agreement (see Note 2).

PROPERTY AND EQUIPMENT: Property and equipment is stated at cost. Depreciation
is computed using the straight-line method over estimated useful lives which are
20 years for land improvements, 35 years for buildings and improvements, and 10
years for machinery and equipment.

In fiscal 1996, the partnership adopted Statement of Financial Accounting
Standards (SFAS) No. 121, "Accounting for the Impairment of Long Lived Assets
and for Long Lived Assets to be Disposed of." SFAS 121 requires that long-lived
assets be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying value of the asset may not be recoverable. In
evaluating long-lived assets held for use, an impairment loss is recognized if
the sum of the expected future cash flows (undiscounted and without interest
charges) is less than the carrying value of the asset. Once a determination has
been made that an impairment loss should be recognized for long-lived assets,
various assumptions and estimates are used to determine fair value including,
among others, estimated costs of construction and development, recent sales of
comparable properties and the opinions of fair value prepared by independent
real estate appraisers. Long-lived assets to be disposed of are reported at the
lower of carrying amount or fair value less cost to sell.

The adoption of SFAS No. 121 did not have a material effect on the partnership's
financial statements.

INCOME TAXES: No provision has been made for federal or state income taxes on
partnership net income, since the partnership is not subject to income tax.
Partnership income is includable in the taxable income of the individual
partners as required under applicable income tax laws. Certain items, primarily
related to depreciation methods, are accounted for differently for income tax
reporting purposes (see Note 5).

NET INCOME PER LIMITED PARTNERSHIP UNIT: Net income per limited partnership unit
is based upon the weighted average number of units outstanding during the period
which amounted to 8,751 for all years presented.

USE OF ESTIMATES: The preparation of the financial statements in conformity with
generally accepted accounting principles requires management to make certain
estimates and assumptions that affect the reported amounts of assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

NOTE 2 - PARTNERS' EQUITY

Pursuant to the partnership agreement, annual partnership net income is
allocated one percent to the General Partner and 99 percent to the limited
partners. A partnership net loss in any year will be allocated 24 percent to the
General Partner and 76 percent to the limited partners until the losses so
allocated equal income previously allocated. Any additional losses will be
allocated one percent to the General Partner and 99 percent to the limited
partners.

Partnership gains from any sale or refinancing will be allocated one percent to
the General Partner and 99 percent to the limited partners until allocated gains
and profits equal losses. Additional gains will be allocated 24 percent to the
General Partner and 76 percent to the limited partners.

In 1986, the General Partner contributed additional capital of $280,000 to the
partnership in order to provide funds necessary to complete the sixth and final
restaurant.
