In this appeal, a landlord challenges a judgment entered after trial to a jury in the Housing Court Department of the Trial Court, awarding damages and attorneys’ fees to a tenant for injuries caused by unsanitary conditions in her apartment.
Gem Realty Company (Gem) 1 managed a large number of apartment buildings in Boston. It rented many of its *93 apartments to low income tenants under a Federal rent supplement program. From December, 1973, to November, 1977, Celeste Solomon and her two young sons lived in the basement apartment of a building managed by Gem. In December, 1976, Gem began summary process proceedings to evict Solomon for nonpayment of rent. Solomon, citing floods, trash, rats, roaches, and more, denied that she owed rent. She also filed a counterclaim in four counts, claiming that Gem had (1) broken its implied warranty of habitability; (2) violated its implied covenant of quiet enjoyment; (3) caused Solomon emotional distress through its negligent failure to maintain her apartment; and (4) intentionally inflicted emotional distress.
Solomon’s counterclaims are based primarily on her allegations of flooding in her apartment. She testified at trial that water and sewage, flowing from an adjoining basement area, flooded her apartment approximately thirty times during her tenancy. Solomon could not recall the date of any of the floods, but was able to name the months in which floods had occurred. She testified that each flood had occurred between twelve and two o’clock in the morning; she described stepping from bed into ankle deep water and slime. Each time this happened, Solomon would spend the night in her kitchen, drinking coffee, and waiting for the morning to call Gem. According to Solomon, a Gem cleanup crew would arrive several hours after her call to pump the water from her apartment. Solomon’s testimony concerning the flooding was corroborated by photographs showing water damage, and by witnesses who had seen water or evidence of water in Solomon’s apartment.
Solomon did not suffer bodily injury as a result of the flooding. She testified, however, that the floods caused her great emotional anguish. The recurrent water and sewage left her “withdrawn,” “depressed,” and “ashamed,” unable to work or to care for her children. She began to spend much *94 of her time in a darkened bedroom, crying, and on two occasions she sent her children to stay with relatives, so that they might escape the conditions in her apartment. Two psychiatric experts testified that Solomon had suffered serious emotional injury as a result of her living conditions, and was in need of substantial psychiatric treatment.
Gem admits that water entered Solomon’s apartment on several occasions, but denies that thirty “floods” occurred. At trial, Gem’s employees described in detail Gem’s maintenance procedures and its answering service for tenants’ complaints, and testified that they had no memory or record of repeated reports of flooding in Solomon’s apartment. Gem also gave evidence concerning the structure of Solomon’s building and the possible cause of flooding, and argued that third persons were responsible for any floods that occurred.
The judge granted summary judgment for Gem on Solomon’s count for negligent maintenance, reasoning that a claim of negligence could not support recovery for purely emotional harm unaccompanied by physical injuries. The judge submitted the remaining three counts to the jury. 2 The jury returned verdicts for Solomon on each count, awarding her $35,000 for recklessly inflicted emotional distress, $10,000 for breach of the covenant of quiet enjoyment, and $1,000 for breach of the warranty of habitability. The judge subsequently awarded Solomon counsel fees, as permitted by the “quiet enjoyment” statute, G. L. c. 186, § 14, in an amount of slightly more than $40,000. Gem has appealed the judgments entered on the verdicts and fee award. Solomon asserts that she is entitled to recover the total of the three verdicts, and the counsel fees, and has ap *95 pealed the summary judgment for Gem on her count for negligently-caused emotional distress.
We affirm the judgments entered for Solomon on her claims for breach of the warranty of habitability, reckless infliction of emotional distress, and attorneys’ fees. We also affirm the judgment entered for Gem on Solomon’s claim of negligence. We vacate the $10,000 award for interference with quiet enjoyment.
1.
Reckless infliction of emotional distress.
Our decisions in recent years have firmly established that a plaintiff may recover for emotional distress inflicted recklessly or intentionally.
Agis
v.
Howard Johnson Co.,
Gem does not seriously challenge the finding of the jury that Solomon suffered severe emotional distress as a result of the floods in her apartment. Instead, Gem stresses that Solomon did not identify a specific “defect” in the apartment building that Gem, as landlord, should have repaired. On this basis Gem argues that it did not act recklessly, did not engage in outrageous conduct, and did not cause Solomon’s floods.
The central thrust of Gem’s contentions appears to be that its conduct was not the proximate cause of Solomon’s injuries — that it was not legally responsible for her misfortune. As Gem points out, the source of the floods was not clear. The water appears to have entered Solomon’s apart *96 ment primarily from an adjoining basement area. Two waste stacks, admittedly very old, extended from roof to basement collecting waste from the bathrooms, and on occasion may have backed up through a drain in the basement. Gem’s plumber, however, testified that the plumbing system and stacks were in good repair and complied with State plumbing regulations. He also stated that backups in the waste stacks were probably caused by objects that other tenants had introduced through the toilets or roof vents. On the basis of this uncontroverted testimony, Gem argues that it acted reasonably in its plumbing maintenance and therefore was not responsible for the flooding.
Gem’s legal responsibility, however, depends on the duties it owed to Solomon, and Gem’s arguments concerning plumbing misstate the scope of a landlord’s duty to its tenants. We have held that every landlord that rents residential property warrants to its tenants that the premises will be delivered and maintained in a habitable condition.

Crowell
v.
McCaffrey,
There was evidence at trial that the wall between Solomon’s apartment and the adjoining basement area was extremely porous. There was also testimony suggesting that Gem may have considered cementing the wall to prevent floods, but never carried out this plan. The jury could reasonably conclude that Gem’s failure to do so caused Solo-
*97
man’s injuries — that but for Gem’s inaction, no floods would have occurred.

See
Williams
v.
Fontes,
Having recognized that an inference was warranted that Gem failed in its duty to prevent the flooding, we find ample evidence in the record from which the jury could conclude that the remaining elements of an action for reckless infliction of emotional distress — recklessness, outrageous conduct, and severe emotional distress
4
— were present. See
Agis v. Howard Johnson Co.,
*98 In sum, it could be found that Gem violated its duty to Solomon recklessly, by outrageous omission to act, and thereby caused Solomon severe emotional harm. Therefore, the jury were warranted in holding Gem liable for reckless infliction of emotional distress.
2.
Negligence and strict liability.
Solomon has appealed the summary judgment against her on her count for negligent maintenance. As the trial judge noted in his order, we have not recognized a cause of action for negligently inflicted emotional distress unaccompanied by physical injury.
Dziokonski
v.
Babineau,
We need not decide whether a tenant could recover for purely emotional harm on a theory of negligence or strict liability, or whether the Legislature intended to authorize such recovery as “consequential” damages under G. L. c. 186, § 14. We have affirmed Solomon’s sizeable recovery for reckless infliction of emotional distress, and she has not demonstrated that she would be entitled to additional compensation if permitted to recover under a lesser standard
*99
of fault. It is perhaps conceivable that the verdict for recklessly inflicted emotional distress did not cover all of Solomon’s suffering. If the jury based their findings of recklessness and outrageous conduct on the repetitious nature of Gem’s conduct,

Liability under G. L. c. 186,
§
14.
The judge’s award of attorneys’ fees, and parts of his instructions on damages, were based on G. L. c. 186, § 14, which imposes civil and criminal liability on a landlord that “willfully or intentionally” fails to provide essential services that it is obligated to furnish, or “directly or indirectly interferes with the quiet enjoyment of any residential premises by the occupant.”
5
A
*100
landlord that violates § 14 is subject to a fine or imprisonment, and is liable to its tenants for “actual and consequential damages or three months’ rent, whichever is greater,” plus costs and attorneys’ fees. See
Darmetko
v.
Boston Hous. Auth.,
First, Gem argues that § 14 does not create an independent civil action — that it cannot be the basis of a civil recovery until the landlord has been convicted under its criminal provisions. We reject Gem’s interpretation. The statute states that one who “commits” any of the proscribed acts is civilly liable; it does not require “conviction.” Moreover, a requirement of prior criminal conviction would defeat the efficiency of the civil remedy as a means by which tenants can enforce the statute and obtain compensation. This is particularly true in the context of summary eviction proceedings. By the express terms of the statute a tenant may apply its claims under § 14 against a claim for rent by the landlord. If a prior criminal conviction were required, however, tenants would rarely be able to raise such counterclaims in summary eviction proceedings based on nonpayment of rent. A statute should not be read in a manner that defeats its intended utility. See, e.g.,
Commonwealth
v.
Lamb,
Second, Gem contends that § 14 prohibits only intentional conduct by a landlord. As we noted earlier, the jury did not find that Gem intended to harm Solomon. It did find, however, that Gem acted recklessly. With this finding in mind, we consider the purposes, language, and context of § 14.
Section 14 belongs to a body of statutes establishing tenants’ remedies against landlords who fail to provide safe and sanitary housing. See, e.g., G. L. c. 111, §§ 127A-127L, c. 186, §§ 14, 15E, 15F, 18, 19; c. 239, § 8A. These stat
*101
utes are designed to facilitate enforcement of State housing regulations and to provide relief for tenants deprived of decent homes. See
Boston Hous. Auth.
v.
Hemingway,
Of course, general statutory objectives do not necessarily justify the broadest reading possible. See
Morissette
v.
United States,
When § 14 was first enacted, both categories of prohibited conduct — failure to provide services and interference with quiet enjoyment — were modified by the words “willfully or intentionally.” St. 1927, c. 339, § 1. In 1973, the statute was rewritten. St. 1973, c. 778, § 2. The requirement of intentional conduct was retained for failure to provide essential services, but deleted from the quiet enjoyment clause; landlords were now liable for “directly or indirectly” interfering with tenants’ quiet enjoyment of leased premises. One natural inference from this amendment is that the Leg *102 islature meant to abrogate the requirement of specific intent to disturb quiet enjoyment.
The common law background of
§
14 also suggests that malicious intent is not a condition of liability. The phrase “quiet enjoyment” is a familiar term in landlord-tenant law, signifying the tenant’s right to freedom from serious interferences with his tenancy — acts or omissions that “impair the character and value of the leased premises.”
Winchester
v.
O’Brien,
Gem argues that because criminal penalties are possible under § 14, we should read a requirement of intent into the statute despite the contrary suggestions of its language and background. We disagree. Although we have often stated that penal statutes should be strictly construed,
Commonwealth
v.
Clinton,
As its third objection to Solomon’s recovery on her count for interference with quiet enjoyment, Gem asserts that it was wrongly held responsible for the actions of third parties beyond its control. Pointing to its plumber’s testimony that waste backups were caused by tenants’ using unauthorized washing machines or introducing objects into the waste stacks, and to its unsuccessful attempts to evict tenants for using washing machines in their apartments, Gem argues that it was unable to control the source of the flooding. Cf.
Blackett
v.
Olanoff,
*104 In sum, we hold that a tenant need not seek a criminal conviction before claiming damages under G. L. c. 186, § 14. Nor must the tenant prove that the landlord intended to interfere with the tenant’s rights, at least as long as the landlord’s conduct was reckless. Finally, Gem is liable to Solomon under § 14 because it violated its underlying duty to maintain sanitary conditions in her apartment, and thereby permitted repeated flooding to occur that interfered with her quiet enjoyment of her apartment.
4. Evidentiary rulings. Gem challenges the admission of two items of evidence. First, Gem asserts that the judge improperly allowed an expert witness to give an opinion on Solomon’s truthfulness. The witness in question was a psychiatrist who testified, on the basis of an interview with Solomon, that she had suffered serious emotional disturbance as a result of the conditions in her apartment. The judge refused to allow this witness to state directly his opinion on Solomon’s truthfulness during the psychiatric interview, but did permit the witness to testify that he ordinarily assessed patients’ truthfulness. The judge also permitted Solomon’s counsel to ask the witness what factors he had relied on in reaching his conclusion that the floods in Solomon’s apartment were the cause of her distress. Immediately after this question, the judge instructed the jury that they alone were responsible for determining the truth of the parties’ allegations, and that they should consider the witness’s comments on truthfulness only as evidence of the process by which he had formed his opinion and the facts on which he had relied. 8 The witness then answered that he had relied in *105 part on statements by Solomon concerning conditions in her apartment, and on the fact that she “appeared sincere and honest.”
The role of an expert witness is to help the jury understand issues of fact beyond their common experience. Under modern standards, expert testimony on matters within the witness’s field of expertise is admissible whenever it will aid the jury in reaching a decision, even if the expert’s opinion touches on the ultimate issues that the jury must decide.
Commonwealth
v.
LaCorte,
Nevertheless, the psychiatric witness’s testimony was admissible as an explanation of the basis of his opinion. An expert witness may state the grounds on which he has relied in forming his opinion, as part of the foundation for his testimony.
Commonwealth
v.
Massachusetts Turnpike Auth.,
Gem’s second argument respecting evidence is that the judge should not have admitted two tenant complaint slips taken from Gem’s telephone records. The slips were dated January 26, 1978 — several months after Solomon had moved out of her apartment. They showed that the new tenant had called Gem to complain that the ceilings were leaking and the “bedroom, living room and hall” were “flooded.” The judge admitted these complaint slips for the limited purpose of showing that Gem’s maintenance supervisor had notice of a “flood,” and thereby impeaching his testimony on cross-examination that the only subsequent tenant complaint had involved “seepage through the bedroom window.” 10
*107
Gem argues that Solomon could not properly introduce extrinsic evidence to impeach testimony on “collateral” matters. The trial judge, however, might reasonably have determined that Gem’s knowledge of complaints received from the tenant who succeeded Solomon, and the maintenance supervisor’s truthfulness concerning tenant complaints, were not collateral to the issues at trial. See 3A J. Wigmore, Evidence §§ 1003-1004 (Chadbourn rev. 1970). In any event, a judge, in his discretion, may permit impeachment by extrinsic evidence even on collateral points.
Commonwealth

Damages.
Gem objects to the judge’s extensive instructions on damages, arguing that the judge misstated the damages authorized by G. L. c. 186, § 14, and incorrectly permitted the jury to assess redundant damages. Gem did not press these objections after the charge was delivered and before the jury retired, and therefore cannot claim appellate relief on the basis of defects in the instructions. Mass. R. Civ. P. 51 (b),
We observe at the outset that much of the confusion that has arisen on the question of damages is attributable to the form in which the case was submitted to the jury. The jury were asked to return separate verdicts on the three counts of Solomon’s claim, and responded by awarding $1,000 for breach of warranty, $10,000 for interference with quiet enjoyment, and $35,000 for infliction of emotional distress. Despite their tripartite form, however, these verdicts represent an assessment of the monetary consequences of a single problem — the flooding in Solomon’s apartment. 11 In our analysis, therefore, we shall take an overview of the claims and corresponding damages, and avoid the misleading influence of the division of verdicts.
In his instructions to the jury, the judge outlined the damages available under each of the three theories of recovery advanced by Solomon. For interference with quiet enjoyment, he instructed the jury to award the statutory measure *109 of damages under G. L. c. 186, § 14: actual and consequential damages, or three months’ rent, whichever is greater. Actual and consequential damages, he explained, included rent paid in excess of the apartment’s value, income lost as a result of injury, and “any damage resulting from emotional distress.” For breach of the warranty of habitability, the judge instructed the jury to calculate the difference between rent paid and the value of the apartment in its defective condition. Finally, he described the elements of damage for reckless infliction of emotional distress as lost income, medical and psychiatric expense, and past, present and future pain and suffering.
In light of these instructions, the verdict for interference with quiet enjoyment, if based on Solomon’s actual damages, necessarily duplicated both the lost rental value awarded for breach of warranty, and the items of damage awarded for infliction of emotional distress.
12
Nor can the verdict be justified on the basis of the alternative measure of damages under § 14 — three months’ rent. Triple rent damages, as the judge correctly instructed the jury, are appropriate only when they exceed actual and consequential damages. G. L. c. 186, § 14.
Darmetko
v.
Boston Hous. Auth.,
Solomon suggests that the jury might have arrived at the $10,000 verdict for interference with quiet enjoyment by
*110
assessing three months’ rent for each of a number of separate conditions — such as rodents, overflowing toilets, and a collapsed ceiling — that were present in months when no flooding occurred. She explains that three times her monthly rent of $313, assessed for ten violations, would yield a figure of approximately $10,000.
13
Such an award, however, would be inconsistent with the judge’s instructions that all of Solomon’s claims were based on the flooding, see note 11,
supra,
and we assume, of course, that the jury complied with those instructions. See
Stricker
v.
Scott,
The limitation does not, Solomon suggests, immunize a once recalcitrant landlord from liability for future violations. If new violations arise after the initial suit is filed, the tenant may recover triple rent in a new proceeding. Further, if the landlord persists in or repeats the original violation after a final judgment in the tenant’s favor, the tenant may repeat his suit and recover a second time.
In sum, taking into account the relationships among the three counts of Solomon’s claim, and the instructions that accompanied their submission to the jury, we find no acceptable basis for the verdict awarding $10,000 to Solomon for interference with quiet enjoyment. The jury could only have reached this verdict by duplicating items of damage subsumed in Solomon’s recoveries for breach of warranty and emotional injury, or by making unwarranted use of the triple rent clause of § 14. Accordingly, we vacate it.
When the improper $10,000 verdict is removed, no overlap remains in Solomon’s damages. The verdict for breach of warranty reflects only lost rental, value, while the verdict for infliction of emotional distress represents only damages for personal injury. Therefore, we affirm the $35,000 and $1,000 verdicts in Solomon’s favor.
6. Attorneys’ fees. After trial, the judge assessed attorneys’ fees of slightly more than $40,000 for Solomon, based-on the fee provision of G. L. c. 186, § 14. Gem’s primary objection to this award is that the judge improperly considered legal services related to Solomon’s claim for emotional distress.
A statutory fee award should not cover effort expended on independent claims that happen to be joined with statutory claims in a single proceeding. See
Hanner
v.
Classic Auto Body, Inc.,
Section 14 provides that tenants may recover “actual and consequential” damages from landlords who have interfered with their quiet enjoyment of leased premises. We have noted that this provision was intended to expand the damages recoverable for breach of the covenant of quiet enjoyment.
Darmetko
v.
Boston Hous.
Auth.,
We also reject Gem’s contention that the fee award was excessive and unreasonable. The judge made detailed findings as to the fee award, following the guidelines we set out in
Linthicum
v.
Archambault,
In sum, we affirm the judgments for Solomon for reckless infliction of emotional distress, breach of the warranty of habitability, and attorneys’ fees. We also affirm the judgment for Gem on Solomon’s claim of negligence and strict liability. Finally, we vacate the $10,000 judgment for Solomon for interference with quiet enjoyment, and direct that judgment should be entered for Gem on that aspect of the case.
So ordered.
Notes
The company was controlled by Maurice Simon, since deceased, who was the original plaintiff in this action. For purposes of brevity, we refer *93 to the owner-landlord as Gem. No question is raised as to Gem’s control of the premises.
The jury were asked to return a separate verdict on each count, and to answer ten specific questions. In the answers to these questions, the jury found that Gem had broken its implied warranty of habitability and its implied covenant of quiet enjoyment. They also found that Gem had not intended to cause Solomon emotional distress, but had engaged in outrageous conduct, and had known, or should have known, that this conduct would cause emotional distress. Finally, they found that Gem’s conduct caused Solomon’s distress, and that her distress was severe.
Gem’s arguments focus on the causal connection between its conduct and the flooding, rather than that between the flooding and Solomon’s injuries.
The severity of Solomon’s injury is not an issue on this appeal.
In relevant part, G. L. c. 186, § 14, as amended through St. 1974, c. 192, § 1, provides that:
“Any lessor or landlord of any building or part thereof occupied for dwelling purposes, other than, a room or rooms in a hotel, but including a mobile home or land therefor, who is required by law or by the express or implied terms of any contract or lease or tenancy at will to furnish water, hot water, heat, light, power, gas, elevator service, telephone service, janitor service or refrigeration service to any occupant of such building or part thereof, who willfully or intentionally fails to furnish such water, hot water, heat, light, power, gas, elevator service, telephone service, janitor service or refrigeration service at any time when the same is necessary to the proper or customary use of such building or part thereof, or any lessor or landlord who directly or indirectly interferes with the furnishing by another of such utilities or services, or who transfers the responsibility for payment for any utility services to the occupant without his knowledge or consent, or any lessor or landlord who directly or indirectly interferes with the quiet enjoyment of any residential premises by the occupant, or who attempts to regain possession of such premises by force without benefit of judicial process, shall be punished by a fine of not less than twenty-five dollars nor more than three hundred dollars, or by imprisonment for not more than six months. Any person who commits any act in violation of this section shall also be liable for actual and consequential damages or three months’ rent, whichever is greater, and the costs of the action, including a reasonable attorney’s fee, all of which may be applied in setoff to or in recoupment against any claim for rent owed or owing.”
section 14 itself permits landlords to provide in lease contracts that they are not liable for conditions resulting from natural causes beyond their control. This provision suggests that liability was not intended to be absolute.
In Blackett, a case decided after the enactment of § 14 in its present form, we held that “the landlord’s conduct, and not his intentions” determine whether he has violated the implied covenant of quiet enjoyment. 371 Mass, at 714, 716 (1977).
After Solomon’s counsel asked the witness to describe the factors on which he had relied for his conclusions, the trial judge stated that “any statements that the witness testified that he relied upon [are] only being admitted for the purpose of showing the basis of his opinion. ... In other words, it’s simply being admitted to show the information that he had when he formed his opinion. I’m not allowing it to be introduced to show the truth of those facts. The jury will have to make its decision with regard to what facts in the case are true.” In his final instructions to the jury, the judge again emphasized that “ [t]he jury is the sole judge of the credibility of the witnesses.”
Gem also objects that the witness should not have referred to flooding and other conditions in Solomon’s apartment except in response to hypothetical questions referring to specific evidence admitted in court. See
Commonwealth
v.
Russ,
The judge instructed the jury that the evidence was “not being admitted for the truth of what is on those two telephone records but simply to establish that Gem Realty had notice of the complaints, and it’s being of *107 fered ... for whatever value it has to discredit the testimony of Mr. Patterson who testified concerning his recollection of complaints received.” The slips were recorded after this suit commenced, and therefore were not admissible for their truth under the “business records” exception to the hearsay rule. G. L. c. 233, § 78.
Solomon testified to other conditions, unrelated to the flooding, that might have supported a warranty claim or a quiet enjoyment claim. It is clear, however, that each of Solomon’s counts was based primarily on the flooding; the other possible violations played no part in her closing argument, and the trial judge stated in his instructions that all three claims arose from Solomon’s allegations of floods. In any event, as the following discussion will show, we have taken into account the evidence of secondary violations in our analysis of the damages Solomon received.
Solomon’s counterclaim also alleged that the floods had caused property damage — an item not covered by her recoveries for breach of warranty and infliction of emotional injury. The amount claimed, however, was far less than $10,000, and so it could not have been the basis of the verdict for interference with quiet enjoyment. As a result of our disposition of the case, Solomon’s property damage may go uncompensated. Nevertheless, we do not feel that a remand for calculation of this damage is warranted; Solomon, like Gem, failed to point out the problems in the judge’s instructions, and must now bear the consequences of the confusion in the damage awards.
Solomon’s rent was paid in part by the Federal government, through a rent subsidy program. Gem asserts that the relevant figure for calculating three months’ rent is not the contract rent of $313, but the amount that Solomon paid personally: $73. We disagree. The triple rent clause is not a compensatory provision; it is an alternative to actual damages, designed to deter violations and to encourage tenants to seek relief under § 14. See
